PHOSPHOR-BRONZE GERMAN SILVER THE RIVERSIDE METAL CO, RIVERSIDE, N. J. Cod THE IRON AGE New York, Thursday, July 2, 1908. The Besly No. 18 Piston Ring Grinder. For grinding the sides of piston rings rapidly and accurately to size, Charles H. Besly & Co., 15-21 South Clinton street, Chicago, Ill, have designed a new type of grinding machine shown in the illustration herewith. The novel feature of this machine is that the grinding is done on a steel disk wheel, which has its sides cov- ered with Helmet spiral abrasive disks, which are manu- factured exclusively by the builders. This machine will grind rings from the smallest diameter up to 10 in. diam- eter very rapidly and accurately. The machine as shown carries 18-in. disk wheels. The spindle is 134 in. diameter by 25 9-16 in. long, and is made of crucible machinery steel. The bearing bushings are 8 through a crank and lever, the crank being attached to a lower shaft, which is in turn driven by a spur gear mesh- ing a gear on a worm gear shaft. They latter shaft is driven by a worm on a shaft, which is plafed in the lower part of the base at right angles to the spindle, and pro- jects at the rear, where it carries a pulley driven direct from the countershaft by a quarter-turn belt. On the worm gear shaft is mounted a clutcn which when en- gaged causes this shaft to make four revolutions and then releases automatically. The four revolutions are sufficient to produce a forward and return movement of the platen head. On the platen is mounted a compound slide which also has a reciprocating motion, but perpendicular to the face of the disk wheel. This slide receives its motion The No. 18 Piston Ring Grinder Built by Charles H. Besly & Co., Chicago, II. in. long and are fitted in bored holes in the base casting, thus insuring perfect alignment, as well as making it easy to replace them when worn out. The bushings are split and the base has removable caps over the bushings, facil- itating removing the spindle when necessary. End ad- justment of the spindle is accomplished by means of a threaded collar, which is mounted on the spindle just under the flange of the spindle pulley. The end thrust is taken on hardened and gréund steel thrust collars of large area. The bearings are well protected from dirt and grit, and particular attention has been given the lubricating of all bearing parts. The spindle pulley is 7 in. diameter and is driven by a 6-in. belt. One the right side of the machine and secured to the bed is a dove-tailed bed plate, on which is mounted a platen or carriage. Tyus platen has a reciprocating motion parallel to the face of the disk wheel, effected through a gear and rack underneath the bed. This gear is driven from a cam, which is secured to the outer edge of the bed plate. On the slide is mounted the head or bearings of a spindle which carries a chuck for holding the work to be ground. This head can be moved back and forth through a screw and hand wheel. The screw has‘a mi- crometer dial graduated to thousandths of an inch and governs the distance of the chuck from the face of the disk wheel. The chuck is a magnetic rotating one, driven through bevel and spur gears from a shaft in the base of the machine. Through a sliding gear in the base a rapid or slow motion can be obtained across the face of the disk wheel. The operation of the machine is as follows: The work is placed in the chuck and the lever is tripped, causing the platen to move forward; the chuck carrying the work moves toward the face of the grinding disk and the rotating work comes in contact with the grinding disk, and instead of grinding in one place only, the whole 2 THE IRON AGE face of the work is ground at once. As soon as the platen makes its full forward stroke it recedes, and near the end of the latter stroke the chuck carrying the work also re- cedes from the face of the grinding disk. As soon as the full backward stroke is made the platen and chuck stop automatically . The working parts are thoroughly en- cased and protected from dust and grit, as can be seen in the engraving. The hight of the machine from the floor to the center of the spindle is 42 in., the floor space occupied 30 x 48 in. and the complete weight 3000 Ib. —_——_——--o-+e Baush Special Multiple Drills. The multiple spindle drilling machines shown in the illustrations are two special types installed at the plant of the Bethlehem Steel Company, South Bethlehem, Pa., and constituting a part of the equipment of the mill for manufacturing the new Bethlehem structural steel sec- tions under the Grey process. The group consists of eight double head horizontal and four single head ver- tical drilling machines arranged in a line, with every other machine on a sliding base, to accommodate the drilling of any required length of steel. The double head horizontal machines are for drilling flanges, each heail sustaining the drilling pressure of its opposite. The ver- tical machines are for drilling the web. This arrange- ment permits of the necessary-drilling with the minimum handling of the work. These machines were designed and built for this special purpose by the Baush Machine Tool Company, Springfield, Mass., and embody the stand- ard features of the company’s line of this class of tools. The double head horizontal machines are in two sizes, one carrying 12 x 48 in. heads and the adjustable spindles covering any layout within that rectangle. Each head has 18 drill spindles. The other size carries 12 x 24 in. heads. with 10 spindles to each head. The heads can be operated independently or together as desired. The ver- tical machines are also in two sizes, one carrying 16 drill spindles on its single head in a working rectangle of 12 x 36 in., and the other 10 spindles in a rectangle of 12 x 24 1h. All spindles in the entire group of machines have No. 3 Morse taper sockets, and are designed for drilling 1-in. holes in soft steel at a speed of 55 ft. per minute at the periphery of the drill, with ranges of feed up to 0.01 in. per revolution of the spindle. Each head is equipped with a two-speed quick return of the drill heads. In both types of machine each head is independently driven by a variable speed motor, and each movable ma- chine has an extra motor for adjusting its position. The 18-spindle heads are driven by 25-hp. motors, the 16- spindle heads by. 20-hp. motors and the 10-spindle heads by 15-hp. motors. The vertical machines weigh about Double-Head Horizontal Multiple Spindle Drilling Machine July 2, 1908 A Vertical Single-Head Baush Multiple Drill, Also Built for the Bethlehem Steel Company. 11,000 Ib. and the horizontal machines about 25,000 Ib., exclusive of the motors. Each head has an oil pump, pan reservoir and connections to spindles to allow of lubri- eating each drill. lp ete a Arrangements have been perfected by the Droeges, owners of the Licking Rolling Mill Company, Covington, Ky., which has been in a state of litigation for some time, to resume within 30 days. Bids are now being taken on the repairs necessary and for some minor de- tails of construction. The mill has been idle since Feb- ruary 6, when fire destroyed the central portion of the structure. Fred Droege will be the president of the re- organized company.

Accurate and noiseless running gearing is much sought and special machines and accessories for produc- ing them are being continually developed and perfected. In machines using the rotary milling or disk cutter it is considered by some advisable to first rough out the teeth with a roughing-out or stocking cutter before finishing. Some five or six years ago, Gould & Eberhardt, New- ark, N. J., brought out what they term their stepped style of stocking cutter for roughing out the teeth of coarse pitch gearing, preparatory to finishing with a standard finishing cutter. The advantages claimed over the or- dinary square saw or slotting cutter which had previous- ly been used most generally in this country, was that by having the steps in the cutter the chips were broken up, and consequently less power was consumed and the strain on the machine and parts was not so great as with the old style of cutter, the principle of which produces a long shearing cut, with its incidental disadvantages. Again, the lower step of the cutter takes away the wide flank of the gear tooth space, which the square stocking or slotting cutter did not do, and in this way it left a more nearly uniform amount of metal all around for the finishing cutter to take out. While the idea was not new at the time this cutter was put on the market, this firm claims the credit for first exploiting and marketing it in this country. Since then the cutter has been still further improved, and re- cently the new stepped style of stocking cutter, shown in Fig. 1, was patented. The essential difference between this and the older stepped cutter is the recessing of the tops of the cutting teeth, so that each tooth practically takes out about half as much as before, as shown in Fig. 2. The new stocking cutter also finishes the bottom of the tooth space, thereby relieving the finishing cutter of this work, and saving it where it usually wears out first. Finishing cutters with these new features can also be furnished. The principal claims for the new cutter are that a maximum amount of stock is removed with a minimum amount of power consumption; that the cutting edges be- ing staggered are more thoroughly lubricated while cut- ting; that they save the finishing cutters by removing the stock where the ordinary saw cutter leaves large cor- ners at the points of the gear teeth, and that they are considerably wider through the hubs than a saw or slot- ting cutter, lessening the liability for keys to shear off, Fig. 1.—The New Stocking Cutter for Cutting Gears, Made by Gould & Eberhardt, Newark, N. J. THE IRON AGE 3 Fig. 2.—-Detail Illustrating the Action of the New Gould & Eberhardt Stocking Cutter. and in consequence of all of the above permit of faster feeds and speeds being used, and at the same time lessen considerably the strains on the machine itself. Cn a ee Business Men to Be Columbia Teachers. Some leading men in the manufacturing world will appear at Columbia University, New York, as lecturers in the engineering schools at the next session. For some time there have been occasional lectures by such men on special subjects, bit their design has been rather to stimulate the students than to give them systematic in- struction. The new scheme aims at an addition to the course by a regular series of lectures given by men active- ly engaged in business, with the definite idea of bringing the university into touch with the requirements of every- day life, and to teach students how not only a result may be obtained theoretically, but how it may be reached with the utmost economy. : In pursuance of the general plan arrangements have been made by Dean Frederick A. Goeze and Prof. Charles E. Lucke, head of the Department of Mechanical Engi- neering, assisted by Charles B. Going, editor of the Engineering Magazine, to secure men of the highest repu- tations as practical engineers to deliver courses at Colum- bia next fall on engineering. Among the men who will become for the nonce university lecturers are James M. Dodge, president of the Link-Belt Company, who will describe the different kinds of conveying machinery; Charles U. Carpenter, president of the Herring-Hall- Marvin Company, who, as well as Mr. Going, will give his experience of the management of works; James Newton Gunne, who is one of the foremost authorities on shop costs and processes; Richard T. Lingley, who will unravel to the students the mysteries of the accounts of works, and Harrington Emerson, who is down for a course on shop efficiency. Special types of machines will be explained by leading authorities, such as William P. White, who has designed the largest water turbines in this country; Frederick W. O’Neil of the Nordberg Mfg. Company, who will discuss air machinery, and Frederick Ophuls, manager of the De La Vergne Machinery Company, refrigerating ma- chinery. ides cached iliac The puddling mill to be erected by A. M. Byers & Co., Inc., at Girard, Ohio, will require considerable new equip- ment. The plant will contain 40 puddling furnaces and two finishing mills. The building for the latter is to be 103 x 300 ft, and the building to contain the puddling furnaces will be 80 x 408 ft., both of steel construction, with corrugated steel siding. Increased power will be needed for the new plant, and the firm is in the market for ten 125 hp. boilers and a 750 hp. engine. A 16-in. three-high roughing mill and a 12-in. three-high finishing mill, squeezers, &c., will also be required. The Rockdale Iron Company’s furnace at Rockdale, Tenn., which has been on foundry iron, was changed to ferrophosphorus on July 1. It is reported that some good business has been booked for the latter product. 4 THE IRON AGE The Farwell Aeronautic Motor. What is claimed to be the lightest motor of its power ever constructed, is that designed by F. O. Farwell and built by the Adams Company, Dubuque, Iowa, particu- lurly for propeiling airships. The illustration shows two of these motors, one running and the other stationary. to demonstrate the lightness and steadiness, they were held by two men while the photograph was taken. The weight, including timer, float feed carburetor, automatic force feed oil pump and oi] tank, is only 9714 1b. for 86 hp., or 2.7 lb. per horsepower. The single throw crank- shaft, weighing only 4}. ib., is stationary, and the five 414 x 314 in, cylinders set 7 it and up to 1800 rev. per min., producing a gyroscopic action which is of value in an airshiy to steady iis flight. Other novel feaiures are that the motor has no flywheel, no reciprocating parts, no mufiler and no cooling device, that the valves, 10 in number, are actuated by a single 2 degrees apart revolve around July 2, 1908 central crank case, is cast in one piece of steel of high tensile strength, and weighs only 7% lb. Five of these cylinders are bolted together and bolted to a top alumi- num flange (which also forms the gas manifold) weigh- ing 3 lb., and to a bottom steel flange which also sup- ports the valve cam and transmission gear. These flanges have long bronze bushes and form. bearings around the vertical stationary crank shaft. In each cylinder is a cast iron piston weighing 2% lb. All the pistous are connected to the single crank pin by bronze connecting rods which interlock each other around a bronze lined steel bush around the crank pin. The cooling is one of the most important features. The cylinders move rapidly through the air like the arms of a centrifugal blower. Centrifugal force removes the air in contact with the cylinders and atmospheric pres- sure supplies fresh air. The circulation of air is equally rapid on all sides of all cylinders, and as the cylinders are of equal thickness on all sides the expansion is equal and the eylinders may be made light without distortion. Two of the Farwell Air Ship Motors Made by the Adams Company, Dubuque, Iowa, Showing One Running to Illustrate the Absence of Vibration. cam and are closed by centrifugal force instead of by springs, and that centrifugal force also introduces the gas into the cylinders under pressure. The motor is con- trolled like a Corliss steam engine, and the ignition sys- tem is the same as used on ordinary single cylinder motors. The motor is similar to the revolving cylinder motor used in the Adams-Farwell motor car, and described in The Iron Age November 3, 1904, but of much lighter weight. With the spider shown in the photograph, which, in this case, secures the motor to four tubes, the motor and base and all weighed 104 lb. The light weight of this motor, which is air cooled, is brought about more by the simplicity of its construction and the high grade o7 the material used than by reduction of strength to the minimum. The motor is not what is usually termed a rotary engine. The cylinders revolve around a common center—the vertical stationary crank shaft and the pis- tons and connecting rods revolve around another com- mon center—the single crank pin. At one point the pis- tons reach the head of the cylinder; at another point the pistons approach the base of the cylinder, but no mov- ing part éver comes to a stop while the engine is running. It is a continuous circular motion and there is no shock, vibration or loss of power in overcoming the inertia of reciprocating parts as in other motors. Each cylinder, complete with head and part of the The result is entirely different from blowing air upon one side of a cylinder or row of cylinders. The revolving element that acts as the balance wheel is over SO per cent. of the entire weight of the motor. This heavy flywheel revolving rapidly around a vertical axis exerts an enormous force to keep the motor and that to which it is attached in a horizontal plane. The motor, like a top, has a tendency to resist being tipped over while spinning and to quickly right itself if forcibly thrown out of its proper running plane. This force can be utilized to maintain equilibrium in a flying machine. The heavy flywheel is also conducive to steady running and transmits a constant torque to the propeller. A gaso- line motor, particularly one using high compression, transmits its power by a series of explosions or blows, and even though several cylinders may be used to divide up the impulses, the arms of the propeller or fan used to propel a flying machine are subjected to destructive strains unless a flywheel of sufficient weight is interposed between the motor and propeller. The heavy flywheel permits using high compression which is more econom- ical and produces more power from the same size cylin- der than the low compression usually used in automo- bile and aeronautic motors. This heavy flywheel, to- gether with the variable compression system used for controlling the motor speed and power, permits of a very wide range of speeds. Lf RR NE NN Ae gE on ~ eRe ERATE DTN So —————— 1 July 2, 1908 The variable compression system referred to has been used for several years on the automobile engines and con- sists in mechanically holding the inlet valve open for a part of the compression stroke and closing it after a part of the gas has been blown back and taken in by another cylinder which is at the time on the suction stroke. The compression is relieved and the motor is easily turned when it starts and runs slowly. The compression may be gradually increased until maximum speed and power is obtained and it may be as gradually reduced when stop- ping the motor. There is not that abruptness in start- ing or stopping which characterizes the ordinary gaso- line motor and the propelling arms are thus relieved of much strain. After the motor is started the spark lever is set and requires no further attention. All speeds are obtained by the variable compression lever. The proper firing is cared for automatically. The valves, being in the head of the cylinders, and closing outwardly, are closed by centrifugal force. The higher the speed of the motor the greater the force and the greater the necessity for a stiff force to close the valves quickly. The two motors illustrated are now being used by a well known inventor who is making secret tests of a new type of aeroplane. If these tests result as favorably as might be expected in consideration of the advantages possessed by the motors a practical ‘“ heavier-than-air ™ flying machine may become a reality this summer. ————__3--e—_—_- A Walsh Turret Bench Press. The machine illustrated has a tu*ret carrying four sizes of punches or tools for doing various work, such as bending, shearing, wire cutting, riveting, embossing, &e., and is built by the H. C. H.

Each separate slide in the turret is independently adjusted, so that in the grinding of punches or dies the wear can be taken up. There are no springs or delicate mechanism in this machine to pre- vent its standing the hardest usage. Any nuinber of turrets can be had with this machine, so that tools need not be changed for various operations. The turret is easily removed from the machine, as there are no screws to loosen; it is simply necessary to draw the front locking bolt and lift the turret out, replacing it with one to be used. There is an adjustable gauge on the side which can be set at a given distance, allowing any number of strips to be punched with any sized hole at this given distance with no change, The capacity of the machine for punching is a 5-16-in. hole through 4-in. stock, and it will punch a hole in a strip 144 in. from the edge. The benca machine with one turret weighs 170 lb. and when fitted on an iron table and legs 310 lb. These machines will be built in various sizes to suit the requirements of the trade, and will be fitted to be worked either by hand or power. ————@~—-e—_—__ Metillure.—At a recent meeting of the French Soci- ety of Civil Engineers Ad. Jouve reported on the op- portunities for utilizing ferrosilicon alloys in the chemi- eal industries. Ferrosilicon, or “ metillure,” as he has called it, has the property of showing extraordinary resistance to acids, and this has led to the suggestion that vessels for the chemical industry be made of it. It may be that platinum may be replaced in the manu- facture of sulphuric acid. A new outlet would be found for ferrosilicon which is now exclusively used in steel manufacture. 6 THE IRON AGE The Milwaukee 16-in. Engine Lathe. The new lathe shown in the accompanying engravings is an improved 16-in. plain engine lathe, built by the Mil- waukee Machine Tool Company, Milwaukee, Wis. This machine is a tool designed principally for manufacturers desiring durable powerful machines capable of high cut- ting speed. The lathe is of an extra heavy design and differs from the ordinary plain lathe in having quick change attachment for all feeds. It has four changes of belt driven feeds and one feed taken from the lead screw when a coarser range of positive feeds is required. The feeds are driven by a wide belt mounted on two single faced pulleys, provided with a conveniently located belt tightener. For thread cutting the different pitches are obtained by change gears, which are furnished to cover a range of from 3 to 36 threads per inch; this also pro- duces a range of positive feeds when engaged with the lead screw of from 10 to 108 per inch. The belt feeds have a range of from 30 to 80 per inch. The apron is fitted with a clutch for the longitudinal traverse, and a sliding gear for the cross feed. The ma- chine has reverse in the apron and a sliding lock for the half nut. Special care has been taken in the design and placing of all handles so as to be most convenient for the operator. The bed is of heavy pattern, having unusual depth, and is strongly reinforced with heavy cross ties. The head and tailstock are massive in construction, and are fitted to a large V bearing in the rear and a flat bearing on the front. The headstock is designed with two large oil reservoirs located directly under the spindle, from which oil is supplied to the bearings by wicks. The tail- stock is so formed as to leave clearance for the compound rest when used for angular feeds. The carriage is fitted to the bed by a large V bearing in the rear and front. It has a wide cross slide and a compound rest of large proportions. The main spindle bearings are of phosphor bronze scraped to a bearing surface; the main bearing is 3 3-16 x 5 in. long. The spindle has a 1 9-16 in. hole running its length, is made of high carbon crucible steel cut from the solid and is ground. The centers are of tool steel with No. 4 Morse taper shanks. The cone pulley is un- usually large, taking a 214-in. belt, and having a diameter of 11 in. on the largest step. All pinions and gears of importance are of steel cut from the solid. All studs throughout the machine are of steel hardened and ground. The Milwaukee lathe is at present built only in the July 2, 1908 View of the Head End of the New Milwaukee Lathe. 16 in. size, which can be furnished with any length of bed from 6 to 16 ft. The net weight of the machine with an 8-ft. bed is approximately 2500 Ib. complete, the ma- chine is well proportioned throughout, the weight being evenly distributed. A double friction countershaft, com- pound rest, steady rest, follower rest, large and small face plates, together with all necessary change gears and wrenches, are furnished with each machine. The Niles Car Mfg. Company, Niles, Ohio, recently built, in three weeks, two passenger cars for the Mil- waukee Northern Railroad. The cars are of the com- bination smoking and passenger type, with a seating ca- pacity of 52 persons. Each is 50 ft. 4 in. long, over all, and 40 ft. 2 in. long over the body. The passenger compartment is 28 ft. 1 in. long, and the smoking com- partment 8 ft. 2 in. A special baggage vestibule, 8 ft. 3 in. is also provided. The New 16-In, Engine Lathe Built by the Milwaukee Machine Tool Company, Mi!waukee. Wis. July 2, 1908 THE IRON AGE 7 The Schellenbach-Hunt Protractor. A new mechanical device for laying out angles and di- viding circles is shown in the accompanying illustration. It is made by the Schellenbach-Hunt 'Tool Company, Cin- cinnati, Ohio, and can be used on a drafting board, as shown, or attached to a metal plate. It is useful in the tool-room, drafting department or pattern shop. The center gear around which the arm swings has 144 teeth, and can be placed in any position and held stationary. The arm swings around this gear from its central stud and carries a pinion of 18 teeth meshing the stationary gear. Attached to this pinion is a revolving gear of-135 teeth, shown at the right, which meshes an- other pinion of 18 teeth carrying a pointer. One turn of the arm revolves the pointer or hand 60 times. The dial under the hand is graduated and reads to degrees and minutes. The engraving shows the device in two posi- tions, one attached to the base piece and held on the edge of the drafting board as a bevel protractor. In this posi- tion the blade will move through a half circle. In the other position the base piece is removed and the large The blade of the instrument is 12 in. long. The gears are made of German silver, and the spindles and bearings of steel, hardened, ground and lapped. The weight com- plete is 20 oz. ———qx@mr- oe _-____— The Western Electric Company’s Improvements. Plans embracing a project that in extent and indus- trial importance outranks any similar work of the pres- ent year in that vicinity are announced by the Western Electric Company, Chicago. These include the erection of three buildings which will be added to the group com- prising the company’s new plant at Forty-eighth avenue and West Thirty-second street, known as the Hawthorne Works. Some idea of the extent of these additions is conveyed by the fact that between $500,000 and $600,000 will be expended in their construction. It is interesting to note that the plans outlined are not merely tentative, but that the new buildings will be started at once. That expansion of such magnitude should be planned for exe- cution at this time, when the present capacity is only Two Ways of Using the Mechanical Device for Laying Out Angles and Dividing Circles, Made by the Schellenbach-Hunt Tool Company, Cincinnati, Ohio. gear held in the center of the board by thumb tacks passed through holes in the web of the gear. In this position the blade is free to move through the full circle. One edge of the blade is radial with the center of the station- ary gear. A sliding block for a scriber or pencil is shown attached to the blade. The indicating hand can be set to any desired position in relation to the dial and clamped by knurled thumbscrews. In using the device to divide a circle into 144 spaces, for example, the radial face of the blade is set in the desired position, and the hand moved to zero on the dial and clamped to the spindle. The blade is then moved until the hand coincides with 150 min. on the dial; the line is marked, and the blade next moved to indicate 300 min., etc. For dividing uneven numbers, as 47, for instance, a vernier hand reading to 5 min. can be fur- nished. As 47 will not divide in even minutes the frac- tional parts of the minutes will have to be estimated on the dial—a full circle, 21,600 min., divided by 47, equals 7 deg. 39 27-47 min. The hand is set at zero on the dial, and the blade moved to the right until the hand makes one revolution and 9914 min. on the dial; for the second division the hand is turned one revolution and to 199 min., and so on, partially occupied, is particularly significant of confi- dence in the future development of business; it likewise emphasizes an appreciation of the opportunities offered under present conditions for the economical prosecution of such work. - Since the establishment of the Hawthorne plant, man- ufacturing formerly done in the Clinton street plant, lo- cated in the block bounded by Van Buren, Harrison, Clin- ton and Jefferson streets, has been gradually transferred to the new location, and when the additions are com- pleted all manufacturing operations will be concentrated at that point. It is also the purpose of the company to trans- fer to the Hawthorne plant a large portion of the work now done in New York. One of the objects in view in ex- tending plant facilities at Hawthorne is to provide ade- quate facilities for the manufacture of large dynamos and the building of steam turbines, which constitute a recent line of development in the company’s undertak- ings and will be largely extended. The location at Haw- thorne affords exceptional facilities for economical pro- duction. The plant is provided with adequate shipping facilities through a well arranged system of tracks, and the site is large enough to admit of a convenient plant layout. Ses eee | i 1 | ve) The New Walcott & Wood Shaper. Although in general following the usual design, the shaper recently produced by the Walcott & Wood Machine Tool Company, Jackson, Mich., has a number of important details intended to correct what are com- monly weak points. Figs. 1 and 2 show front and side views of a 20-in. high speed crank shaper of the new design, and it will also be built in 16 and 24 in. and prob- ably larger sizes in the future. Among the parts that the builder considered could be improved were the ram bearings. After an experience of years in the designing, building and operating of shapers, the company concluded that the ordinary square form of ram bearings with caps screwed on to hold the ram to its work, even if suitable for general work, do not stay true long enough to be satisfactory where very accurate work is required; and besides they are likely to give under heavy cuts, producing a fan-tail cut. To over- THE IRON AGE July 2, 1908 upward bearing of the ram substantially flat, this wedg- ing tendency is avoided. The design of the ram has been improved also by dis- pensing with the long slot usually necessary for the Clamping stud. This is accomplished by placing the clamping device for binding the ram to the rocker arm entirely within the shell of the ram, so that a box form of ram is allowed with an unbroken outer surface and crossribs from side to side at short intervals its entire length, thus making what is claimed to be the strongest ram ever put on a crank shaper. The binding device is operated from a wrench hold @ projecting through the top of the ram. The construction of this clamping ar- rangement is shown in Fig. 8. AS may be seen, the inner surface of the ram has two lateral longitudinal ribs which engage the positioning nut b. The lower rear end of this positioning nut is cut away, admitting the clamp- ing plate c, which is caused to bind upon the ribs and the positioning screw d at the same time. The clamping is done by means of eye-bolts and an eccentric lever, which is operated by a rack, e, through a pinion on the lower end of the stem of the wrench hold a. The tool head is of a familiar design, but strongly constructed throughout. It is graduated, and swivels to any angie through an are of 90 degrees, and has an ad- Fig. 1.—The New Shaper Built by the Walcot. & come these defects the ram bearings of this new shaper are constructed as shown in the halftone Fig. 1 and in the drawings Fig. 3. The ram has flat bearings under- neath, a very wide side bearing tapering slightly out- ward and upward and a wide top bearing tapering slightly upward and inward. The column is cast with recessed ways to receive the ram bearings, and taper wedge gibs are provided to take up wear. To maintain the sidewise alignment of the ram the side bearing is more than 60 per cent. greater than customary. The lower is proportioned to the side bearing surface so that the ram will wear downward in its bearing, and the side bearings, being tapered outward and upward, auto- matically compensate the lateral wear. The bearing surfaces on the ram are virtually surrounded on three sides by the solid metal of the colmmn, which is appar- ently the strongest possible construction. When screwed on caps are used, fitting the ram bearing surfaces at an angle of 45 degrees, there is a tendency for the ram to wedge under the upward pressure of a heavy cut, pro- ducing uneven work and chatter marks. By making the Wood Maciine Tool Company, Jackson, Mich. “ustable graduated collar reading to 0.001 in. on the down feed screw. The tool head slide has a graduated scale and pointer to indicate the depth of cut; the pointer is adjustable so that it can be set to an even division of the scale. The clapper box is strengthened by a tie rib f connecting both sides at the bottom, which greatly in- creases its rigidity. The tool head has a strap tool post and power down feed, as shown in Fig. 3. The down feed mechanism consisis of the rail g mounted on top of the column and a dog adustable along the rail and having a projecting pin which engages with the slotted lever h. The motion of the lever is positive in both directions, re- quiring no spring to return it. It is connected with the down feed screw, as shown, by gearing and a ratchet which can be thrown in and out at will. The driving gexrs are unusually strong and the back gear ratio very large. The main Crive is from a four- step cone driving pulley which runs on the outside of a stem cast on the column, through a double sliding gear i on the cone shaft and back gears on an intermediate shaft, which conrect with the bull gear j. On the other 7 | | : ee July 2, 1908 THE Fig. 2.—Front View of the New Walcott & Wood Shaper. end of the bull gear shaft is an elliptical gear, k, which meshes a second elliptical gear attached to the main driving crank Il. The elliptical gears give a suitable quick return of the ram and a greater power during the cut without necessitating excessive speed of the shafts and gears. The elliptical gear arrangement is considered preferable in construction to the Whitworth quick return and gives a smooth, positive drive, besides eliminating the wear that attends the Whitworth quick return, The drive gives eight cutting speeds for each length of stroke é b. om A =P SECTION THROUGH RAM CLAMP d. oe eS AND STROKE LENGTH > INDEX DRIVE SECTION THROUGH ORIVE CF DOWN FEED eae aa aS CE RPEy 4 aa re hak 7 ? eS rT <> f > N _ “ 4 “4 H rs AN Bi-w- Nu oot IL ter a fi ts} Fars rao 4 4 SSI = END SECTIONAL ELEVATION Fig. 3. IRON SIDE ELEVATION PARTLY IN SECTION AGE 9 and is smooth and powerful. back gears is 32 to 1. The driving crank 7 is made very strong and rigid, the bearing for the crank being large and long, as shown in Fig. 8, and integral with the column. The length of stroke is adjusted by means of a shaft passing through the center of the crank, which, through gears, turns the screw m and alters the position of the adjusting nut and crank pin so as to increase or decrease the throw of the crank. The nut n slides iff ways on the face of the crank / and is provided with a long bearing and a taper gib to take up wear. The ratio of gearing with The rocker arm is a very important part of a shaper and its design has been given especial attention. It is unusually long and, when the ram is at either extreme of its stroke, is less than 15 degrees from perpendicular. Unnecessary friction and wear on the ram bearings due to excessive angle of the rocker arm are thereby avoided. The recess for the crank block is of box form, as shown in Fig. 3, and contains a taper gib to take up wear. The fork in the top of the rocker arm allows shafting to be passed through under the ram for cutting keyways. The pivot pin at the top of the rocker arm connecting it to the positioning nut has a very large bronze-bushed bear- ing and is tapered to take up wear. The cross rail is of box form and is designed to with- stand the strain due to taking heavy cuts. Its bearings o on the front of the column are slightly bevelled on the outside to adjust for wear without having to rely upon the pressure of a few gib screws to maintain the align- ment. The cross rail is long and deep and has ample bearing surfaces for the apron. The apron is provided with a taper gib to take up wear. The table is of box form and can be detached readily to allow work to be clamped to the face of the apron. The table is locked to the apron in a simple and effective way, as shown in the halftone Fig. 2, and also has a convenient detachable outer support. The table cross feed mechanism is quite out of the ordinary, doing away with necessity for adjusting the feed to correspond with the hight of the cross rail. As shown in Fig. 3, it consists of the miter gears p and q connected by a splined shaft to transmit motion from the bull gear shaft to the small crank r, which, through a connecting rod, actuates the rocker s. This rocker has an adjusting screw and trunnion nut which is connected by a rod to the ratcht lever ¢ mounted on a stud in the RZ = > > |e | TERRA ie of ys Pee ; PARTIAL SIDE ELEVATION ~Constructional Details of the New Walcott & Wood Shaper. 10 THE IRON AGE cross rail. The ratchet operates a gear which meshes a pinion uw loosely mounted upon the cross rail, but con- nected to the cross feed screw through a spring clutch y capable of sliding on the screw. This spring clutch intro- duces a yielding link in the transmission so that if the table accidentally runs to the extreme of its travel the pressure on the clutch teeth forces the clutch out of mesh and prevents breaking any parts. For convenience in adjusting the length of stroke an index is provided to show it. This index, v Fig. 3, is a dial on the side of the machine just above the stroke ad- justing shaft with a pointer oscillating over its face. This pointer is driven through gears by the rack w which is connected by the screw z to a lug on the ram position- ing nut. All bearings are bushed with bronze bushings and all rapid running bearings have ring oilers, the construction of which is shown in Fig. 3. The driving cone has two half bushings with oil chambers between them; a splasher attached to the pulley throws the oil up over the stem and keeps the bearings thoroughly lubricated. Convenient oiling facilities are provided for all running or sliding bearings. All shafting is of steel ground to size, and all gears are cut from the solid, are coarse pitch and wide face, and all pinions are of steel. The vice, as shown on the halftones Figs. 1 and 2, is designed to rest flat upon the top of the table, this form- ing the most rigid possible construction. It has a swivel base and is graduated. The maximum stroke of the machine is 20 in.; the length of ram bearing in the column 36 in.; the keyseat- ing capacity 3% in.; the horizontal travel of the table 27 in., and the feed to the head 7 in. A 3-in. driving belt is used, which runs from a countershaft having 44x 14 in. tight and loose pulleys. The countershaft is intended to run at 350 rev. per min. The net weight of machine and countershaft is 4100 Ib. a ee Customs Decisions, Steel Channels for Automobile Frames, It has been decided by the Board of United States General Appraisers that side frames and cross pieces used in the construction of chassis for automobiles are dutiable at the rate of 5-10 cent per pound under para- graph 125, providing for channels or car truck channels. The articles were imported by the Napier Motor Com- pany of America, and were assessed for duty by the col- lector of customs at 4 7-10 cents per pound under the paragraph in the tariff for “ steel in all forms and shapes not specially provided for.” The decision of the board says in part: “From the testimony and the exhibits in the case, we are inclined to regard the contention of the importers in this case as well founded. Not only does the testimony offered in behalf of the importers show that the steel articles in question are channels, but it further appears that even the witnesses for the Govern- ment admit that in shape the articles are channels, and that they are not complete manufactured articles. Thus the articles appear to be ordinary steel channels for car trucks, and require to be further manipulated before they are ready to be used as finished frames for automobiles. The protest is sustained.” Steel Wool. The Treasury Department announces that inasmuch as the Supreme Court has refused to grant a writ of certiorari in the litigation over the tariff classification of steel wool, the decision of the Circuit Court of Appeals favorable to the contention of the Buehne Steel Company, the importer, will stand. The Government, backed by domestic manufacturers, has brought several test cases since 1902 to determine the rate of duty applicable to the product. The Board of General Appraisers and courts have almost unanimously upheld the contention of the im- porters for the lower duty. The Treasury Department asked for a 45 per cent. duty, while the importers alleged that the rate should be according to the gauge and value of the wire from which the wool is made. em With the July copy, the Du Bois Iron Works, Du Bois, Pa., has begun the distribution of a series of 12 monthly July 2, 1908 calendars, each bearing a reproduction in colors of one of May A. Post’s paintings of “ Child Life in Holland.” A leaflet accompanies the July calendar, containing a brief description by the artist of each picture. The reverse sides of the cards will contain short talks on the company and its products, engines and pumping machinery. —_—_—_——- eo Oe A New Variab'e Speed Planer Mechanism. The variable speed mechanism shown in the illustra- tion is designed to give two cutting speeds and one con- stant return speed to the planer table of planers smaller than 36 x 86 in. On that size and larger planers four cutting speeds may be had, if desired, by introducing a second clutch. The builder, the Woodward. & Powell Planer Company, Worcester, Mass., has made the posi- tive clutch and the gears of massive construction; there The Variable Speed Planer Drive Used by the Woodward & Powell Planer Company, Worcester, Mass., as Seen from Beneath. is no danger of the clutch slipping out of engagement unless forced out by its lever. The clutch, mounted on an auxiliary shaft, is operated by a lever on the front side of the bed. The pulley A which drives the table on the return is keyed to the main driving shaft. The pulley B which drives the table for the cut has a long hub upon which the loose pulley re- volves, and on the end of the hub is keyed the gear C, which also revolves loose on the main driving shaft. This gear meshes the rawhide gear D, which is keyed to the auxiliary shaft, as is also the sliding clutch. The two self-oiling, cast iron clutch gears on the auxiliary shaft are loose, and mesh rawhide gears keyed to the main
