THE IRON AGE New York, Thursday, July 6, 1905. The Draper 18-Inch Geared Head Lathe. The economical use of machine tools requires that they be run always at the maximum allowable cutting speed. Before the introduction of high speed steel the variation in proper speeds for different diameters of work was less noticeable and four or five step cone pulleys with back gears gave a range that was ample. With high speed steel it has been found possible to increase all for- mer speeds and desirable to extend the range, a fact which has been recognized and acted upon by most build- ers, particularly of lathes, milling machines and drills. Other reasons why the old cone pulley and belt system of changing speeds is being abandoned are that a belt is usually incapable of pulling heavy cuts at slow speeds and cannot be shifted easily and quickly enough to en- courage the workman’s changing speeds as frequently as he should. In a heavy engine lathe, where power is required for rapid reduction or fast cutting speeds in finishing, some form of geared head is coming to be regarded as essen- tial. The accompanying illustrations show an 18-inch lathe, built by the Draper Machine Tool Company, Worcester, Mass., which is equipped with an interesting patent geared head, driven through a single wide face pulley by a 6-inch belt. One advantage of this lathe is that a motor drive may be easily applied without making any radical changes in the construction, and as the geared head provides several mechanical speed changes it is not necessary to use a variable speed motor. One of constant speed form, wound for either direct or alter- nating current, may be used. The lathe has ten possible spindle speeds obtained by sliding gears operated by levers, as shown in detail in the illustrations. Fig. 1 shows part of the lathe with the tail stock and carriage placed in close proximity to the head stock. A detail of the geared head is shown in Fig. 2, this being a view looking down on the mechanism when the cover of the case is removed. Fig. 3 shows three views of the geared head, indicating clear- ly the construction and the manner of its use. Fig. 1.—An 18-Inch Lathe with Patent Geared Head, Manufactured by the Draper Machine Tool Company, Worcester, Mass. Referring to Fig. 3, R is the driving shaft at the back of the lathe and carries two sliding gears, A and B, manipulated by the middle lever at the front of the head. Gears A and B may be alternately engaged with gears C and D on the sleeve BE, which runs loose on the main spindle T. The shaft S, with its four gears, J, K, L and M, takes the place of the usual back gear shaft in an ordinary lathe, and may be thrown out of action by turn- ing the eccentric handle F. The quill on which the gears C and D are mounted may be clutched to the spindle by the knob shown in Fig. 2. With this setting of the mechanism and the shaft R running at constant speed two spindle speeds are possible, the faster one with the gears A and C engaged and a slower one with gears B and D in mesh. By disconnecting the spindle gears C and D from the spindle and throwing the back gear shaft S into action eight additional spindle speeds are obtainable through the gears H, I, N and O on the spin- dle and the gears J, K, L and M on the back gear shaft. With gears A and C engaged either the gears I and K or H and J may be engaged. Gears C, B, H and I being con- nected together and loosely mounted on the spindle, the shaft S may be driven at two different speeds, one with H and J in mesh and the other with I and K engaged. By manipulating the handle at the left in front of the box the drive from the back gear shaft to the spindle may be transmitted either through L and N or M and O. Thus there are four speeds through the back gear shaft with A and C in mesh and similarly four with B and D in mesh. The gears N and O are of course fixed to the spindle. The pan shape of the lower half of the gear easing provides a reservoir in which the gears run im- mersed in oil. The belt driven machine is usually furnished with a two-speed countershaft, so that 20 working speeds are afforded. It is never necessary to run the lathe in the reverse direction, even for thread cutting. For this a dial thread indicator, shown at the right of the carriage in Fig. 1, is provided, which permits odd, even or frac- tional threads to be caught with a half nut after return- ing the carriage by hand when chasing the threads. When the lathe is to be motor driven a cover with projecting pads for the mounting of the motor is substi- tuted for the plain cover, and a train of gears or chain drive connects the armature shaft to the driving shaft at the back of the lathe on which the pulley is ordinarily mounted. Three changes of feed may be had with this lathe without changing gears. It is also made, however, with Fig. 2—The Draper Geared Head with Cover Removed.

These four boats are the largest vessels on the lakes, being 569 feet over all, 549 feet keel, 56 feet beam, 31 feet depth. They embody a number of new principles in marine engineer- ing, straight lines being substituted for arches for greater carrying capacity. i A Pacific Coast Shipping Problem. San Francisco, Car., June 24, 1905.—The important question now before the commercial public, especially the portion of it that imports goods from the East, is what arrangement, if any, will be made with the Pacific Mail Steamship Company for carrying goods from Pan- ama to San Francisco and back again. As the other end of the route and the Panama Railroad are in the possession of the United States Government the old order has passed entirely away, but the same necessity exists of making arrangements to ship goods on a through bill of lading from New York to San Francisco. One bill of lading cannot be given at New York and another at Panama. Necessarily the United States Government must give that through bill of lading, and it must either make arrangements with some responsible company such as the Pacific Mail undoubtedly is or put on steamers of its own between Panama and San Francisco. Of course this the Government cannot and will not do. Then, as the only two steam lines that are at present in the field happen to be foreign corporations, one British and the other German, there would be in the event of an arrangement being made with them the anomaly of the Government fostering foreign commerce in a matter en- tirely within its jurisdiction. Most of the merchants of this city are altogether in favor of having the vessels that take part in this trade not only reliable as far as regularity of arrival and departure are concerned, but also-ships that can fly the American flag. At present the Pacific Mail Company happens to be the only one that can comply with this desideratum. Hence it would seem that if American vessels are employed on this side those of the Mail Company would still hold the field. This is a matter which must soon be settled, as the arrangement between the Panama Railroad and the Pa- cific Mail terminates July 12.

The patent geared head is furnished for lathes of all sizes from 18 to 42 inch swing. oo The third of four great steel steamships being built for the Pittsburgh Steamship Company, a wing of the United States Steel Corporation, was launched at the South Chicago yards of the American Shipbuilding Com- pany June 24. This ship, which is to be the flagship of the fleet, is named the William E. Corey, after the president of the United States Steel Corporation. The sister ships are the Elbert H. Gary, launched at Chicago three months ago; the G. W. Perkins, launched at West pipe and other goods of the same character form the larger part of the goods that come from New York via -anama for San Francisco and the other coast cities; consequently our hardware merchants are more inter- ested in this than anybody else, as far as mere dollars and cents are concerned. The arrival here of the new steamship Dakota has been a matter of great interest. Her cargo consisted of 8760 tons of steel, of which 7000 go to Seattle, the rest being for San Francisco. She is one of the giant steam- ships of the Great Northern Steamship Company and has been visited by crowds of citizens. This is the dull season, as it is called, and no doubt business is quiet as compared with other portions of the July 6, 1905 year, but if so the Clearing House exchanges do not show it. The clearings have improved exceedingly over last year, indicating larger sales, the largest on the whole that San Francisco has ever seen. Notwithstand- ing this there are pessimists even among our bankers, from whom the big clearings come, some of whom pre- dict short crops. Everything, however, is going along at high pressure. Capital keeps pouring into the city, our banks have increased their resources and our merchants are increasing their facilities for doing business. Some have doubled the space they formerly occupied. It is the same with our manufacturing institutions, one of which is about to double its capital and will require a lot of new machinery. Outside of mining machinery and a few other odds and ends the Pacific Coast does very little to supply institutions of this kind, which neces- sarily have to obtain their equipment from the East, J. 0. L. —_——_s-o——————— Test of a Steam Turbine After Two Years’ Service. The following test is cf interest, as there has been little information available concerning the deterioration of steam turbines and its effect on their performance. The test was made by Professors Edward F. Miller and R. R. Lawrence of the Massachusetts Institute of Technology. The machine was a 150 horse-power turbine made by the De Laval Steam Turbine Company, Trenton, N. J., and had been in service continuously for the past two years at the New England Structural Company, East Everett, Mass., for furnishing power and light. Shortly before the test was made the turbine was taken apart and thor- oughly examined. It was found that there was no appre- ciable wear on the pinion or buckets, and many of the latter still had part of the original scale formed when they were drop forged. The machines were furnished under a guarantee not to consume over 18.7 pounds of steam per brake horse- power per hour at full load, or 19.7 pounds at half load, when supplied with steam at 150 pounds pressure and exhausting into a vacuum of 26 inches. Comparing these figures with those obtained in the test it will be seen that the turbines are well within their original guarantees, in- dicating that the deterioration, if any, has apparently not affected the steam consumption.

From the account of the test submitted by the engi- neers it is evident that all proper precautions were taken, and the methods employed were consistent with the ob- taining of accurate results. me Cost of High Speed and Self Hardening Steels. Among the topical discussions at the recent annual convention of the American Railway Master Mechanics’ Association at Manhattan Beach was one on high speed steels. The comparative economy of high speed and self hardening steels was discussed as follows by J. A. Car- hey of the Chicago, Burlington & Quincy Railroad: The almost prohibitive cost of high speed steel] makes one consider carefully whether or not it should be purchased for all classes of work, and especially for old machines which cannot tax the capacity of the cheaper self harden- ing steels. When one figures that a tire lathe tool costs from $8 to $10, it looks like a lot of money. On the other THE IRON AGE 3 hand, if we will take into consideration the slower speed, smaller output, time lost sharpening and dressing tools and the loss of material incident to dressing and sharpen- ing, it will be seen that the cheaper tempering and self hardening steels are too expensive to be considered. A case in question: A set of bolt cutter dies made of 10- cent tempering steel cost 21 cents for labor and 5 cents for material, total 26 cents, and cut 100 bolts before dress- ing. A set of similar cutters made of 75-cent high speed steel cost 37% cents for material and 40 cents for labor, total cost T7%, cents, and cut 1100 bolts before dressing. Enough tempering steel cutters to do the same work would have cost $2.86. This is what I mean when it is said we cannot afford to use low capacity steel. The use of tool holders and smaller sizes of steel will effect great economies in the investment of high speed steel, and in one instance the introduction of tool holders reduced the number of pounds of steel required for a wheel lathe over 80 per cent., and instead of a tool 1 x 2 inches, 18 inches long, costing $7.87, a 1 x 1 x 8 inch tool, costing $1.87, is used, and the tool holder does not wear out or break and costs 5 cents per pound, against 75 cents per pound for high speed steel. Rose bit reamers can be tipped with high speed steel and increase their effi- ciency from 750 to 1000 per cent.; in fact, a little in- genuity and thought will open up economies in the quan- tity of high speed steel that were never given a thought when 10-cent steel was used. Larger section tools of high speed steel which have become too short can be hammered out into tools of smaller section with excellent results. High speed steel has come to stay until some more efficient material is discovered, and while its price may make us question its economy, a second thought will con- vince us that we cannot afford to go back to the cheaper tool steels for heavy work, however good these may be in their class. ———_p-- oe ____—_- The United *States Cast Iron Pipe & Foundry Company.

The expenditures of the Government were $567,411,611 and the receipts were $543,423.859. The deficit for the preced- ing fiscal year was $41,053,422. 4 THE A New®Ridgway Horizontal Boring Machine. In the last issue there was given a description of a new 8-foot radial drill made by the Ridgway Machine Tool Company, Ridgway, Pa. Another tool made by the same company, a horizontal drilling, boring and tapping machine, is illustrated herewith. The views of two op- posite quarters of the machine are shown in the half- tone, the outboard support being omitted in the right-hand view. The column which supports the head with its spindle and operating mechanism is of large box section and earries at the top a pad on which the driving motor is mounted. A peculiar feature of the machine is the sup- port of the drill spindle, which is somewhat similar to that provided in the radial drill referred to above. The spindle is of high carbon steel accurately ground to size IRON AGE July 6, 1905 the power traverse the machine may be quickly run back clear of the work to allow for examination or changing boring bars or cutter heads. A stop on the base plate makes it possible to bring the tool back to the exact posi- tion previously occupied. The rack upon which the traverse is effected as well as the entire machine may be moved and set up in other locations on the base plate, both being secured by clamps in slots in the plate. The motor is one of variable speed type, having a range of 6 to 1, and provides power for rotating the spindle and all of the movements of the head and ma- chine. A belt is used for the drive, being passed succes- sively over the main driving pulley at the top of the column, which is geared to the motor, the spindle driving pulley, the head traversing and feeding pulley and a pulley at the base of the column, which ordinarily runs as an idler, but becomes active in the power traversing A New Horizontal Drilling, Boring and Tapping Machine, Built by the Ridgway Machine Tool Company, Ridgway, Pa. and works in a long sleeve, which is journaled in bronze lined bearings in the head. The object of this mounting. as in the other tool, is to relieve the drill spindle of strain due to the belt pull. The feed mechanism comprises a draw key and slip gears for varying the feed and throw- ing it out or in. The feeding is communicated to the spindle by a spur pinion which meshes in a rack behind the spindle. For raising or lowering the head on the column there is a stationary screw between the guides, upon which a rotating nut travels. The latter can be operated by hand to adjust the head for setting or by power to make a quick change over considerable distance. A _ simple clutch, which may be operated while the machine is running, makes the change from hand to power manipula- tion instantaneously. A weight behind the column coun- terbalances the head. A lateral movement of the column on the floor plate is obtained through a rack and pinion, which may also be operated by either hand or power, a simple clutch, as in the case of the head traverse, accomplishing the change. The lever for the hand manipulation may be seen in both views and is convenient for fine adjustments. Through of the column. It will be noticed that the arrangement is such that the belt length is constant regardless of the position the head may occupy on the column. The motor is reversible for tapping operations and is controlled in speed and direction of rotation by a small controller mounted upon the head, where it is always conveniently reached. By means of the boring bar support shown only in the left-hand view, the range of work which the machine is capable of is greatly increased. This part consists of a column similar to that carrying the drill head and sup- ports an adjustable saddle, which is arranged to receive bushings of various sizes, depending upon the boring bar in use. If the machine is to be used for drilling and tapping only it is furnished without the outboard support and in that shape constitutes an easily handled portable drill. Through the yoke at the top of the column it may be moved from point to point by an overhead crane and set up where required. ——-—_—___~ 0-~@ According to the Railway Age, the mileage of railroad track laid in the United States for the first six months of this year was smaller than for any similar period July 6, 1905 since 1898. Only 1284 miles were laid, although upward of 7000 miles are under construction. Work was greatly retarded by the inclement weather of the spring months. —~+-e—____- May Iron and Steel Exports and Imports. A sharp decrease in the exports of iron and steel for May is shown in the report of the Bureau of Statistics of the Department of Commerce and Labor. The total value of the month’s exports of iron, steel and manufactures thereof, but excluding iron ore, was $12,118,730, against $13,076,975 in April. Taking the commodities for which quantities are given the exports for May were 74,073 gross tons, as compared with 102,516 tons In April, 89,879 tons in March, 70,429 tons in February and 56,810 tons in January.

In submitting his report, covering the condition of the company for the year, President Eaton stated that the output of cars had amounted to 35,857, including all types and designs. This, he added, meant a decrease of fully 30 per cent. as compared with the preceding year. As for the other business of the company, which he stated would amount to about 20 per cent. of the total business, there is shown an increase which is entirely satisfactory to the stockholders. He pointed out that the future of the company was particularly bright and that there were on hand orders for 44,000 cars, which is the largest amount of orders for this time of the year in the history of the company. The officers are as follows: Chairman of the board, W. K. Bixby; President, F. H. Eaton; first vice-president and general manager, W. J. McBride; second vice-presi- dent, E. F.

An extremely simple and novel valve for pumps, com- pressors, blowing engines, &c., has been patented by Pro- fessor Gutermuth of Darmstadt, Germany. The valve is made from one piece of sheet metal, its dimensions and proportions varying somewhat according to the use to which it is to be applied. Fig. 1 shows the typical form of the valve and Fig. 2 the shape of the blank as cut from sheets of carefully selected material (steel, gun metal, &c.) of very high tensile strength and elasticity. The left hand edge of the blank is first bent at an angle, as shown in Fig. 3, and fits into the slot of a mandrel, Fig. 4. The mandrel is chucked in a machine of special design and turned about its axis, coiling the blank, as in- dicated in Fig. 1, only that part remaining flat which is to serve as the flap of the valve. For light pressures, such as occur in blowing engines, the coil and flap are of uniform thickness, as in Fig. 2, but for higher pressures, though the blanks are still in one piece, by a special process two thicknesses are pro- duced. The flat part is left thicker for strength and the coiled part lighter for elasticity, as shown in Figs. 1 and Fig. 1 THE IRON AGE July 6, 1905 in a hinged valve the hinge causes friction, hence is sub- ject to rapid wear, and the only way it may be closed is by weights of springs which increase the momentum and introduce new sources of friction. The Gutermuth valve can be opened to any required degree without straining the material, and the whole of the port is uncovered, as the valve lifts bodily from its seat. The valve is distinguished from all other flap valves in that it has a wiping motion when leaving or returning to its seat, and a very small force is sufficient to open it. The power to raise a valve 4 inches wide, 3 inches long and 1-32 inch thick, having four coils, to an angle of 30 degrees is only 2 pounds, which for the adequate section port area means a pressure of only 0.25 pound per square inch. Such a valve will resist a permanent working pressure of 150 pounds per square inch. Much lighter valves can be constructed for blow- ing engines, or by suitably strengthening the flaps the valves can be successfully used for hydraulic work, for air compressors for liquid air and even for pressures up to 3000 pounds per square inch, and in any case the elasticity of the coil is the same. Gutermuth valves are always so fitted that they cover Fig. 4. Fig, 2. Fig. 3 Details of the Gutermuth Spring Flap Valve. 3. By the proper proportioning of the ports the flap for the highest pressures and heaviest duties need be no thicker than 1-16 inch. To prevent the coils in the flaps from interfering with the clamp, sides of the casings or adjacent valves the blanks are cut a little wider at the end, which becomes the inside of the coil, so that this part is slightiy longer than the rest. The valves are fitted to spindles of similar section but of slightly larger diameter than the mandrels and are secured simply by slipping them on. The spindles are held in position in any suitable manner. by clamps, set screws or otherwise, care being taken that the margin of the flaps are the same on all sides of the ports. Pro- vision is made for turning and locking the spindle to reg- ulate the tension of the valve springs. It is only neces- sary to clamp the spindles at one end, as the pressure from the valves is extremely slight and the valves can be slipped on from the overhanging end, or the spindles may be clamped in the middle and the valves slipped on at both ends, no outside supports being needed. In a measure the action of the valve is similar to that of a hinged flap valve or an elastic blade valve, but it is claimed to have many points of superiority over either. The nature of the spring makes a long continued use of the Gutermuth valve possible; the wear is very slight and the elasticity practically everlasting ; whereas the port opening at an angle, as will be seen in Fig. 5. Advantages gained thereby are that the port is entirely uncovered at a relatively small deflection of the valve, that the resistance of the valve to be overcome by the flow of the water is very small and that the small and peculiar lift of the valve secures a prompt closing when the flow ceases. Another feature of the valve is that no guide is required to prevent it from opening more than sufficient to pass the whole jet. They can be fitted in any position—vertical, horizontal, oblique or in- verted. It will be appreciated that since the valve is of small mass no considerations of momentum enter in, and prac- tically any speed may be obtained by the pump without the slightest danger of failure of the valve to act promptly. Possible applications of the Gutermuth valve are al- most innumerable. Among those which have been put forward by the patentee of the valve as among the most usual are those to new and reconstructed pumps for va- rious duties—feed pumps, sewage pumps, air compres- sors, gas engine charging pumps and blowing engines. In many cases it is possible to save in the space occupied and to increase the speed by modifying the design of the machine so that this type of valve may be used. Fig. 6 shows the construction of a typical valve seat made in ac- July 6, 1905 cordance with the Gutermuth principles and used to re- place the mushroom valve in a vertical differential deep well pump. The usual speed of the pump before the con- version was 80 revolutions per minute and afterward the working speed was 180 revolutions per minute. Fig. 7 shows longitudinal and cross sections of a re- markable pump called the “ Spherical ” boiler feed pump, built by Rustin & Co., Prague, the design of which is said to have been only possible with the use of the Gut- Fig. (;—A ‘Typical Arrangement of Gutermuth Valves. 1 SKK MN A Ss SS Length Section.

The pump proper consists of one com- pact and solid casting, which forms the pump barrel, the seat for the valve cone containing all valves and seats, the suction chamber and the pressure chamber. The pump is single acting, has a plunger 2%, inches diam- eter x 4 inches stroke, and ordinarily operates about 250 revolutions per minute, although in special tests it has worked up to 450 revolutions per minute. Apart from the flanges the only parts that have to be machined are the seat for the valve cone and the plunger barrel. All the valves open straight in the direction of the flow of the water.

It is capable of feeding 1225 gallons at 250 revolutions and 1725 gallons at 350 revolutions against any boiler pres- sure. The two illustrations given of the application of the valve (Figs. 6 and 7) are sufficient to show the possibili- ties of the valve and its wide range of adaptability. x A\ \ ‘ ‘ \ \\ “ \N (pen. The valves themselves are the same in all cases, and in each application it is only necessary to design members to contain the valve seats so as to fulfill the two essen- tial conditions—i. e., that the valve may set diagonally across the port and means be provided for supporting the spindle. — oo Our foreign trade in manufactured products is grow- ing very satisfactorily.

The Board of Aldermen of Boston, Mass., has formally accepted the offer of Andrew Carnegie of an endowment fund of $400,000 to be used for the maintenance of a trade school to be established by the Benjamin Franklin fund, which is the accumulation of a bequest by that eminent American made a century ago. The condition of Mr. Carnegie’s gift is that the institution be patterned after the Cooper Union, New York. A New Buffalo Underwriter Fire Pump. A new model standard underwriter fire pump built in strict accordance with the 1904 specifications of the As- sociated Factory Mutuals is now built by the Buffalo Steam Pump Company, a firm owned and operated by the Buffalo Forge Company, Buffalo, N. Y. The pump repre- sents a development covering over 15 years and has re- ceived remarkable attention to detail in its design. In it it was aimed to make use of all devices aiding proper operations under working conditions; to provide means for detecting, locating and analyzing such troubles as are bound to occur in spite of precautions, and to make the duty of repairing, inspecting, cleaning, &c., easily and quickly executed by making all parts interchangeable and accessible. The pump is of the duplex type, is substantially built and embodies certain improvements suggested by the ex- A New Underwriter Fire Pump, Built by the perience of insurance inspectors. In 1891 specifications were first drawn up by the Associated Factory Mutual Fire Insurance Company for a fire pump which would be more reliable than the type then in use, providing protec- tion in time of emergency by avoiding all danger of stick- ing, bursting, nondelivery of rated capacity or inability to operate at the minimum steam pressure. Close atten- tion was paid to the behavior of such pumps and in 1895 more complete specifications were compiled. These were finally revised and more rigidly applied in 1904, and it is in accordance with these that the pump illustrated is built. The claims for this pump on which the builder lays the greatest stress are that its steam parts, water pas- sages and air chamber are much larger than in common trade pumps, so that a large volume of water can be delivered in an emergency without water hammer, and that it is rust proofed, hence will start instanly after disuse. This is accomplished by making its piston rods and valve rods of Tobin bronze instead of steel and its water pistons, stuffing boxes and rock shaft bearings of THE IRON AGE July 6, 1905 brass instead of cast iron. The valve levers are wrought iron forgings or steel castings. The pump is so designed as to be continuously primed whether wet or dry system is used, but as an additional safeguard a set of brass priming pipes are connected permanently to the water main and are provided with special checks and air cocks. Six large hand holes afford ready access to both sides of the water valves. The vacuum chamber seen at the right of the pump is another feature peculiar to this style of pump and has been found neces- sary for smooth operation when running at high capacity. It will be noticed that there are two suction inlets, per- mitting the most convenient connection with a supply pipe, a blank flange being furnished for the unused inlet. A relief valve of approved make is attached to the delivery pipe immediately under the air chamber and prevents any possibility of wrecking the pump or pipe line through excessive pressure. A pressure gauge on the THEIRON AGE Buffalo Steam T’nump Company, Buffalo, N. Y. delivery pipe and a steam gauge on the valve chest indi- cate at a glance the conditions under which the pump is working. The customary cushioning valves are found on the steam cylinder together with a sight feed lubricator and lever handle pet cocks. All the necessary fittings are furnished with the pump, including a set of two to six hose valves, an over- flow pipe with valve and cast iron relief valve discharge cone, four \%-inch air cocks and checks, a stroke gauge and a capacity plate. These pumps are made in five sizes and are thoroughly tested before leaving the works, the water cylinder being subjected to a pressure of 300 pounds per square inch before approval. ——_— +e —_ The Bureau of Navigation of the Department of Com- merce and Labor has made public its annual shipbuild- ing returns for the year ending June 30, 1905.
