A tool designed especially for the heavier class of mijiing in machine, engine and railroad shops is the new No. 4-B heavy plain milling machine of the Brown & Sharpe Mfg. Company, Providence, R. I. It has been entirely redesigned to meet the unusually severe require ments created by the use of high speed steel cutters, and is much heavier than earlier machines of equal size and capacity. The machine, Fig. 1, is of the constant driving speed type, similar in this respect to other recent milling for milling equal to that of the main spindle itself, or in other words, capable of carrying any cut within the pull the main driving belt. The drive, from an 18-in. pulley with 6-in. belt, is of a ing capacity of standard Brown & Sharpe type, which was described in The lron Age January 14. 1904. are obtained through hardened gears, the ratios of which 21.3 to 1.

Company, Providence, R. I. machines of the company, and is operated either by belt to a single pulley of large diameter, or by electric motor through silent chain and sprockets. A special feature is the friction clutch pulley with brake, used with electric drive, and, if desired, with belt drive, which does away with the necessity of a countershaft. The table and spin- dle speeds are independent. The variable feeding mechan- ism is new and contains interesting and advanced fea- tures, which are shown in the detail drawings. All hand wheels controlling the movements of the table are pro- vided with clutches, each operated by a knob in the cen- ter of the wheel. The table has quick return and slow hand feed, operated by a single hand wheel at the front of the saddle. A screw feed is employed. A massive vertical milling attachment is furnished, with a capacity slow speeds adapted to cutters of large diameter. The 16 changes of speed obtainable from 15 to 350 min. in progression and are effected by manipulating the index slide and the levers on the side of the column. The back gears are thrown in and out by a lever in the usual way, and the locking pins engaging the spindle sleeve which replaces the cone pul- ley are.operated automatically by the movement of this lever. In the driving mechanism, as well as in other parts of the machine, no chains or gears are exposed, all mechanism of this character being inclosed in the frame or attached boxes. The variable feeding mechanism is new in design and gives a wide range of feeds, varying in geometrical pro- gression, that fully covers all regular requirements. For range rey. per geometrical 1632 small mills feeds of from 0.0018 to 0.057 in. per revolution of the spindle are gerferally used, and for large mills, 0.041 to 1.23 in. The 16 possible changes of feed, other- wise expressed, run from %& in. to 20 in. per minute. The gears are all of spur form. The drive is direct from the main pulley shaft by chain and sprocket wheels, inside the frame. The table is driven through universal joints and a train of gears in the reverse box on the side of the knee, to the shaft a, Fig. 2. On this shaft is splined the g oer Fig. 2. Fig. 3.—Vertical Section through the Table bevel gear b, Fig. 3, driving the vertical shaft c, which meshes two bevel gears. The latter are mounted loosely upon the table feed shaft. These gears have clutch faces and either one or the other is engaged with the clutch mounted on the shaft, for reversing the feed, which is in addition to the reverse on the side of the knee that af- fects all the feeds. ‘ The table has quick return and slow hand feed, oper- ated by one hand wheel, h, Fig. 2, at the right and front of the saddle.

With the knob pushed in the clutch is engaged with gear m and a slow feed is obtained, the motion be- ing transmitted through the reducing gears 1, n, n and m. The bevel gear o, through the pinion p and gears r and s, drives the feed shaft. To disengage the hand wheel when using power feed the clutch k is brought to its central position. A spring detent holds the clutch in its different positions. The usual means are also provided for ad- SS N AGE Vertical Section through the Table and Knee, with Details of the Table Adjusting Mechanism. weve Z THE iBON AGE and Knee at Right Angles to That in Fig. 2. justing the table in either direction by a crank handle applied to the squared end of the screw at the left end of the table, as shown in Fig. 2. The automatic trip is actuated by the adjustable dogs f, Fig. 3, on the edge of the table, which depress the plunger g, rocking the shaft / and sliding the clutch shoe i. There are two plungers for the two directions of en- gaging the clutch for feeding to the left or right. It will be noticed that the hand wheels for the longitudinal, transverse and vertical feed shafts are all at the front of the machine, and are convenient when feeding by hand, May 30, 1907 as the operator can manipulate them without taking his eyes from the work. As the vertical and longitudinal feed shafts are placed at an angle on the left and right sides of the knee, respectively, the operator has complete control of the various movements of the machine without Fig. 4.—The Vertical Spindle Attachment and Manner of Sup porting It. Fig. 5. changing his position or removing any handles, and the feeds can be operated simultaneously without interfer- ing with one another. The machine has a longitudinal feed of 42 in., transverse feed of 12 in. and vertical feed of 20 in. An important new feature of the machine, which is embodied if desired, is a friction pulley, details of which are not shown. This can be substituted for the regular driving pulley, thus adapting the machine to be driven direct from a line shaft and doing away with a counter- shaft, a practice which is being adopted by some as more THE IRON ~Vertical Longitudinal Section of the Vertical Spindle AGE 1633 economical. The friction clutch operating the pulley is controlled by levers on each side of the machine near the front. On the left side is a long lever, placed for con- venience in stopping and starting from in front of the machine. On the right hand side is a shorter lever, an- swering the same purpose, but intended only for conven- ience when changing spindle speeds. The clutch is simple in construction, has few parts and is self-adjusting for wear. It operates easily and will drive any cut that the main belt will carry without excessive pressure being ap- plied to the operating lever. The expanding ring is wide and of large diameter, giving ample friction surface. A simple brake is provided which upon the release of the clutch instantly stops the spindle of the machine and acts as an effective lock when removing chucks or cutters from the threaded end of the spindle. A friction pulley of this type is furnished with all motor driven milling machines unless otherwise specified. The machine is particularly well adapted to the ap- plication of motor drive, with either a constant speed or variable speed motor. The single driving shaft feature simplifies the installation of the motor and allows direct drive, by chain and sprockets, from the motor to the ma- chine driving shaft, without need of intermediate gears. A suitable pad is cast on the rear of the machine base to support the motor bracket and allows a motor to be ap- plied at any time, without extensive refitting of the ma- chine. When the constant speed motor is employed the same number of spindle speed changes can be obtained as for the regular belt drive. With a variable speed motor the spindle gearing is somewhat simpler. The sliding gear on the spindle is retained, and with the back gears gives four series of speeds controlled by levers. With a 74-hp. motor (the a \ PP R V7 _ 4) vad a | 2 ie | i —E Attachment size required for the No. 4-B machine) with speed varia tion of 3 to 1, the following series of speeds are ob- tained: 9% to 28% revolutions per minute; 22 to 66; 51 to 153; and 117 to 351 revolutions per minute. Each of these series will have as many intermediate speeds as there are running points on the controller. With a drive from this type of motor there are obtainable 16 changes of feed for each series of spindle speeds, as follows: 0.033 to 1.04 in. per revolution of spindle; 0.014 to 0.453 in.; 0.006 to 0.194 in. ; and 0.0026 to 0.084 in. per revolution of the spindle. THE 1634 The vertical milling attachment shown in perspective in Fig. 4 and in section in Fig. 5 is proportioned to carry any cut within the milling capacity of the main driving belt. The drive is from the main spindle of the machine, in which a clutch arbor carrying a bevel gear is inserted. The latter, through an intermediate bevel gear mounted upon an auxiliary shaft and spur gears drives the spindle of the’ attachment as shown. This arrangement allows of a bearing for the attachment spindle almost as large as that of the main spindle. The end of the spindle has the same size taper hole and a thread of same diameter as the machine spindle, allowing the use of the same collets, chucks, face mills, &¢c., on either the machine or attach- ment spindles. All bearings are bushed with bronze, all geurs are of hardened steel, proportioned to transmit full power of the machine driving belt. The frame of the at- tachment is clamped direct to the face of the knee slide and has an outer support to insure additional rigidity. The weight of the attachment is 500 Ib. A word should be said about the general design of the No. 4-B plain milling machine. It is heavy through out, a proper distribution of metal insuring strength, and those parts most subject to strain being amply propor- tioned to withstand severe service. The spindle has a very rigid support. The knee slide extends to the top of the frame, thus adding to the strength of the spindle bearings and reducing the possibility of any spring in the bearings. ‘The extended knee slide makes it possible to clamp any of the regular attachments to the face of the column so that they become practically a part of the machine. The flat bearings are scraped to surface plates, as a mechanical necessity to insure correct alignments. The box section frame is rigidly braced internally. Bronze bearings are used wherever necessary to insure long wearing qualities of running parts. The weight of the machine is 8200 lb. net. a Production and Consumption of Denatured Alcohol. WASHINGTON, D. C., May 28, 1907.—The reports of the Internal Revenue Bureau upon the production of de- natured alcohol show a small increase for the month of April as compared with March, but the figures, on the whole, are disappointing to those who have anticipated a rapid gain in both production and consumption. The restricted output is attributed, however, to the compli- cated and somewhat drastic internal revenue regulations, and it will be gratifying to all consumers, present and prospective, to learn that the bureau is now engaged in revising the code along very liberal lines. Production to May 1. The output of denatured alcohol in April was 270,- 206.80 gal., of which 240,787.94 gal. were produced in Illinois and 29,418.86 in Indiana. The production in March was but 240,778.32 gal., but in January it was 074,449.36 gal. The internal revenue reports make the following exhibit for the first four months under the free alcohol] law: C~ -— -Gallons.——— Illinois. Indiana.

Regulations to Be Liberalized, The revised regulations will completely revolutionize the present method of distributing denatured alcohol, as they will provide for the enforcement of the supplemental legislation enacted at the last session of Congress. Re- IRON AGE May 30, 1907 tailers of completely denatured alcohol will be relieved of the present requirement regarding the keeping of books and the making of periodical returns to the Internal Revenue Bureau. Tank wagons for the local transporta- tion and distribution of alcohol, similar to those now used for petroleum products, will be authorized; and the cost of the container, which now constitutes a heavy ad valorem tax on the product, amounting to several cents per gallon, will be completely eliminated. The present regulations limit the retailer to sales of 5 gal. to any one individual, but under the revised code this limit will be raised to 10 gal. The dealer using a tank wagon will be rated as a wholesaler and will be permitted to distribute alcohol in any quantity to any one desiring to purchase. These changes cannot fail to stimulate the sale of denatured alcohol, as the requirements thus abolished have prevented thousands of applicants for per- mits to handle denatured spirits from taking advantage thereof, and for some time past more permits have heen currently canceled than have been issued. Movement by Hardware Manufacturers, Manufacturers of hardware using enamels, lacquers, bronzes, varnishes, &¢c., are much interested in the move- ment now on foot to secure a modification in the regula- tions regarding the use of specially denatured alcohol. Soon after the new law went into force the manufactur- ers discovered that the use of benzine or pyridine bases as a constituent of completely denatured alcohol retarded the drying quality of enamels, lacquers, varnishes, Xc., made therewith, and were reluctantly obliged to abandon the use of this grade of spirits. The Internal Revenue Bureau at once authorized a special denaturant consist- ing of approximately 5 per cent. of wood alcohol, but applied to all applicants taking advantage of this formula the exceedingly vexatious restrictions placed on all con- sumers of specially denatured spirits. Manufacturers in the lines referred to have since made a number of elaborate tests and have reached the conclusion that grain spirits denatured with 20 or 25 per cent. of wood alcohol would be available for use if the Internal Reve- nue Bureau would consent to regard the product as com- pletely denatured and therefore subject to no embar- rassing restrictions. Application has therefore been made to the bureau to authorize the proposed formula as a third general denaturant. It is expected that this request will be granted, in which event a very large in- crease in the consumption of denatured spirits will im- mediately result. w.L. Cc. ——- +—~9 +e The Foundry Specialty Company, Cincinnati, Ohio, has sent out two booklets, one devoted to partine and the other to fluxine. Partine is employed both for parting and for facing. Its use, it is said, permits of reproducing the finest tracing on the surface of the pattern, and saves considerable time in polishing because of the smooth- ness of the surface of the casting as it comes from the mold. It is employed on large green sand work as well as on smaller patterns, the powder being dusted over the mold. The booklet dealing with fluxine suggests its use for the removal of oxides, silicates and other undesirable elements in the metal. It is employed also in the elimina- tion of gases, preventing the formation of blowholes. Without attacking the crucible or the furnace lining fluxine is designed to clean the metal and make it homo- geneous and fluid. A careful compilation made by the New York E£ven- ing Post shows that during the last five months—less than half of 1907—the railroads and industrial corpora- tions have issued $912,849,400 in notes, stock and bonds. Of this total the railroads have borrowed $792,440,000, stock issues representing $326,567,400, short-term notes $285,173,000, and bonds $180,700,000. The industrial com- panies have secured $120,409,000, offering $63,750,000 in new bonds, $42,000,000 in notes, and $14,659,000 in stock. This shows that the railroads have already asked for two- thirds of the $1,100,000,000 that James J. Hill last No- vember said they would require annually for five years to come if needed improvements and extensions were to be provided. ; A ASE AD ist NAc POE ti a 80 A AON ATELIER PBL oe viiliomen eine Dine cit DEP Ra FL, «0. ~ ; t : % 4 i ¥ Ane Paik wel ai May 30, 1907 A New Shaking Device for the Chemical Laboratory.* BY J. M. CAMP, DUQUESNE STEEL WORKS, PITTSBURGH, PA. Among the various pieces of apparatus going to make up the equipment of the modern laboratory, it is the purpose of this article to describe the latest appliance in the shape of a shaking device. It was designed and is particularly adapted for the purpose of hastening the precipitation of phosphorous by the well-known and al- most exclusively used molybdic acid method, and in the solution of steels or pig irons for the carbon combustion method, but it is equally useful wherever it is desired to agitate a flask for either dissolving or precipitating. As can be seen from the illustration, it consists of a frame supporting a vertical shaft, which is revolved by a 6-in. grooved pulley. The upper part of the shaft is bent slightly from the perpendicular. Encircling this part is a hub, which in turn supports a flat disk on which the flasks to be shaken are attached. The hub and disk are The Camp Chemical Agitator. prevented from turning when the shaft is revolved by teeth on the under side of the hub meshing in correspond- ing teeth on the top of the supporting frame. On revolving the shaft the motion of the disk is ideal for the purpose intended and can be best likened to the simultaneous pitching and tossing of the deck of a ship in a tumultuous sea. With each revolution of the shaft a wave travels around the flasks exactly as in hand shak- ing, and by varying the speed the number and intensity of the wave movements is controlled. To obtain the maximum agitation and still retain the solutions in the flasks, without corking, from 100 to 140 rev. per min. has been found a very satisfactory speed. The disk is made to hold six flasks, any one of which can be placed in or removed from the machine in a fraction of a second. The gripping device is movable, up or down, enabling it to be quickly adjusted to hold any size flask, from a 6-oz. to a 24-0z. florence or erlenmeyer. The electrical power required co operate it is 0.12 ampere on 250 volts, or about the equivalent of 1-25 hp., less than the average desk fan motor consumes. With a countersbaft to give the ., .

Heat can be applied to the apparatus if desired by means of a circular burner, but it has been found that by adding the liquid hot to the flask, or heating the con- tents before placing the flask in the machine, the same end is obtained. The advantages of the machine over hand shaking are obvious. Not only is the operator relieved of the physi- cal effort, but during the time of shaking he can be doing other work, with the assurance that the machine is not shirking, which might result in false analySis. Then, in phosphorous precipita- tion, for instance, the action of the machine being con- stant, a precipitate of like crystallization is always ob- tained, aiding materially its estimation by judging its bulk, as is the practice in most busy open hearth steel works laboratories. The machine is simple, easy to operate, quiet, and the flasks can be readily placed in and removed from the ap- paratus. The fact that the flasks do not need to be corked is also an advantage. Application has been made and the claims granted for a patent covering the ideas embodied in this machine, and it is the purpose to put it on the market as soon as suitable arrangements can be made. seating dia . A New Power Station at Niagara. The Niagara Falls Hydraulic Power & Mfg. Company is now completing what may be the last great power sta- tion erected on the New York side of the river at Niagara in some years. This station is known as No. 3 and is located at the water’s edge in the gorge. The unit of development will be 10,000 hp. Two of the units are now in place and two others are well along in construc- tion. The first section of the station will have five units and the ultimate capacity of the installation is to be about 100,000 hp. It is from this station that the com- pany contemplates supplying the Aluminum Company of America with electric power for the operation of its mammoth new works, now approaching completion. This new aluminum works, the largest in America, if not in the world, is located on top of the high bank north of the flour mill section on the lands of the Niagara Falls Hydraulic Power & Mfg. Company. It is being built of steel and concrete and is one of the most substantial structures erected in Niagara Falls for manufacturing purposes. Located, as it is, along the edge of the high bank, with the tracks of the New York Central Railroad on the east, the rail facilities for the receipt of raw mate- rial and the shipment of the finished product will be quite ideal. The power company is prepared to supply power as soon as the aluminum company is ready to receive it. The Aluminum Company of America will re- ceive 37,000 hp. from the station. Secretary Taft has approved of the water diversion, as the amount that will be used by the company comes well within the limit established by the Burton Dill. It is noticeable that the power company is doing its utmost to have all features of its construction work, both above and below the bank, come well within the effort to beautify Niagara and this power section. Thousands of dollars of expense are being incurred by the Niagara Falls Hydraulic Power & Mfg. Company in order that it may conform to the efforts to keep the industrial de- velopment in harmony with the scenic features. ———— The Morgan Spring Company’s works at Struthers, Ohio, has made a new high record on its Morgan contin- uous wire rod rolling mill. On May 20 the mill in a sin- gle turn of 12 hr. rolled 101.6 gross tons of No. 5 stand- ard gauge soft Bessemer wire rods in coils. In these days, when there is so much interest among rollers to beat their past records, this achievement in the com- pany’s single strand mill for a single turn is, of course, a source of much gratification to all the interested par- ties. 1636 THE IRON AGE THE FOUNDRYIMEN’S CONVENTION. An Association Formed by Brass Interests.—A Record Attendance. The convention of the American Foundrymen’s Asso- ciation, at Philadelphia, May 21, 22 and 23, of which the first day’s session was reported in the last issue of The Iron Age, broke all records in attendance. At noon of Thursday, the last day of the convention, 1391 persons had registered. This compares with 800 at the Cleveland convention and with registrations of from 200 to 500 at conventions in years preceding 1906. Apart from the unprecedented attendance and the remarkable exhibition of foundry machinery and appliances, the convention was made noteworthy by the organization of the American Brass Founders’ Association. The interest taken by the brass trade in the new organization indicates that in this important field the possibilities of such advance in econ- omies of operation as has resulted from the work of the iron founders‘ association is well appreciated. The absorbing attractions of the exhibition carried on at the Second Regiment Armory under the auspices of the Foundry Supply Association may have lessened the at- tendance at the sessions for the discussion of papers. But there was a great compensating value in the exhibits, since these gave opportunity for seeing practically every form of foundry device in actual operation. Moreover, it is to be questioned if the foundrymen are less remiss in attending the sessions at which papers are discussed than are the members of the average society of engineers. TUESDAY AFTERNOON. Brief mention was made in our report of last week of the papers read at the Tuesday afternoon session of the convention. The paper of E. B. Gilmour, Elizabethtown, Pa., on “ The Evolution of the Foundry Business,” paid particular attention to the gravity molding machine of the Mitchell-Parks Mfg. Company, St. Louis, which was described in The Iron Age of January 10, 1907, p. 180. The speaker said that the basis of the new method was the fact that the most intricate kind of ramming is done by riddling the sand and throwing it into the intricate parts of the mold. The gear wheel was cited as an ex- ample of a mold that can never be rammed successfully in the teeth with a rammer. The gravity principle has now been applied to every part of the mold by the grav- ity molding machine. Another feature of the machine is that a special flask can be adopted the full size of the machine and any number of sections can be put together to get a required depth. In brief, by the gravity mold flasks are rammed by a succession of pressed bodies of sand falling and wedging opposite each other until a layer is formed across the entire area of the flask. Addi- tional layers are then built up in the same manner until the entire mold is formed in a solid mass of sand of the same degree of firmness throughout. In the discussion of the paper of H. M. Lane on “Small Things Often Neglected in the Core Room,” the question of circulation of air in core ovens came up. The speaker made the point that the heat efficiency of core ovens could be greatly increased if the waste heat of the oven were used for partly drying the cores. This has been done in some foundries, the truck of cores being run into one oven where they are dried and then into another whre they are baked. Care is necessary in this connec- tion that no attempt be made to dry cores beyond the point where the hot air escaping from the oven is sat- urated with moisture. The air should be dried before it goes into the core oven if possible. The proper tempera- ture of the core oven depends on the binder used in mak- ing cores and varies from 350 to 550 degrees F. Henry B. Cutter, Seneca Falls, N. Y., told of some ex- periments with a condenser in the core oven. The con- denser consisted of a coil of pipe through which cold water was passed. Such a condenser was put on one side of a core oven aud it was found that the results in baking cores were not so good on the opposite side of the oven. Thereupon the circulation of air in the oven was in- creased. The fuel cost was cut from 25 to 40 per cent. This was done last fall, the tests being suspended when cold weather came on. The undetermined question was whether the better circulation or the action of the con- denser or both caused the reduction in the fuel bill. Mr. Cutter was asked to continue his experiments and bring in the results at the next convention. WEDNESDAY FORENOON. A meeting of brass foundry interests to consider the advisability of forming an association of their own was scheduled for Wednesday morning. It was presided over by Charles J. Caley, New Britain, Conn., who made a brief address on the purposes of the promoters of the new organization and in answering the question who are eli- gible to membership he mentioned brass foundrymen, rolling mill firms, platers, supply men, electric workers, and those identified with the automobile industry—in fact, any one directly or indirectly connected with the working of the nonferrous metals or their alloys. The speaker said that great things have been accomplished in the brass foundry in the past 20 years. The oil melting furnace has become a factor and is making rapid strides, though its field has been limited thus far to heavy cast- ings. It has been unable to replace the pit furnace for light castings, plain and ornamental, as used in builders’ hardware, saddlery, &c. The molding machine has not met with as much success in the brass foundry as it should, owing in part te the character of the work and the cost of making and maintaining patterns . The inven- tor has a problem here in designing a machine in which a standard frame may be used, the frame to be so ar- ranged that by a simple method any gated or loose pat- terns may be attached quickly and accurately. The speaker knew of a dozen firms with thousands of patterns in their vaults who would be only too glad to install molding machines in their brass foundries if they could obtain results without going to the expense of regating their patterns as is necessary with the present molding machines. Mr. Caley said further: “ Handling as I have been hundreds of tons of brass and bronze wrought metal, and knowing the difficulties I have, due to defects in metal, I believe that the rolling mills have their own troubles as well as the foundrymen, and I believe in many ways they can be benefited by membership in our association. The automobile interests claim more than passing notice, on account of the many intricate castings employed—cast- ings that must be accurate and so constructed that they will stand the tensional and tortional strain to which they are subjected. To accomplish the results desired, it is necessary that the foundryman making such cast- ings have in his employ men with a thorough knowledge of the foundry business and its requirements, men famil- iar with coremaking as well as the mixing and melting of metals required in automobile work. Plumbing and steam fitting interests certainly come in for their share of our attention, as they have made wonderful strides in the past 20 years, when we consider the old fashioned closed plumbing and the up-to-date open plumbing, the making of which has caused a revolution in the art of making light, durable castings, The same is true of steam fitting, as many of the valves of to-day are cored, where years ago they were bored. Steam pressure has been raised without showing any bad effect, which would go to prove that an advance had been made in the mix- ture of metals to the extent that the cored valve of to- day is lighter by one-third than the valve of years ago.” Mr. Caley was followed by Paul Kreuzpointner, Penn- sylvania Railroad, Altoona, Pa.; Hugh McPhee, Bridge- port, Conn.; Edro Richardson, Baltimore, Md.; W. H. Parry, Brooklyn, N. Y.; J. M. Gamble, Kewanee, Ill.; J. H. Sheeler, Philadelphia ; Charles Thomann, Crosby Steam Gauge & Valve Company, Boston, and Messrs. Thompson of Bridgeport, Conn., G. W. Wright of Reading, Pa., and Bellows. All were of the opinion that an association May 30, 1907 Bh peti Die lO i a a eee May 30, 1907 devoted to brass foundry and kindred interests would have an important field of endeavor and would result in great good to all connected with these industries. The study of brass mixtures, it was said, would prove an im- portant line of inquiry for the new association. The preparation of molds, particularly the gating of molds, and the pouring of the metal at proper temperatures are all matters which might be investigated and discussed with profit. The outcome of the discussion was the de- cision to proceed to the formation of a brass founders’ association, and committees on Constitution and By-Laws and on Nomination of Officers were announced as given in The Iron Age of May 23. Papers were read by An- drew M. Fairlie, Copper Hill, Tenn., on “ Science Applied to the Brass Industry,” and by Charles H. Proctor, Ar- lington, N. J., on “ Electro Deposition of Brass.” The papers of Walter B. Snow, Hyde Park, Mass., “A Plea for Healthful Conditions in the Brass Foundry”; of C. E. Johnson, Dorchester, Mass., “ Notes on Brass Cast- ings”; I. L. Antisell, Perth Amboy, N. J., “ Copper for the Brass Foundry,” and William H. Parry, Brooklyn, N. Y., “A Few Denatured Brass Foundry Notes,” were read by title. In his paper entitled “A Plea for Healthful Condi- tions in the Brass Foundry ” Walter B. Snow of the B. F. Sturtevant Company, Hyde Park, Mass., called attention to the constant irritation of mucous surfaces to which workers in brass industries were subjected, the dust of corundum and emery peculiarly irritating. He showed that mechanical means are absolutely necessary to maintain a rapid air change and insure the proper re- moval of dust. The fan blower has been employed to secure these resultsgits action being positive and of suf- ficient intensity to create an ample movement of air. When warranted by the size of the plant the fan may form part of a blower heating system by means of which warm air from a central heater is delivered under pres- sure through pipes to all parts of the building. The paper was accompanied by views showing the proper ar- rangement of hoods for upward exhaust in connection with emery wheels; an arrangement for the carrying of pipes beneath the floor;.also special hoods designed to give freedom to workmen in grinding departments, as well as a buffing lathe with special form of trap hoods. WEDNESDAY AFTERNOON. The Work of Foundry Trade Schools, W. W. McCarter, Marietta, Ga., was the first speaker at the afternoon session. Without reading his paper, entitled “Some Facts Concerning Trade Schools,” he told briefly of the foundry school he is operating on a commercial basis, the only school of the kind in this coun- try so far as he was informed. There are twenty stu- dents at present, divided into three classes. The seniors are producers; the juniors “ semi-producers,” performing the part of helpers and participating in ramming and drawing of patterns, while the freshmen line up ladles, charge the cupola and make cores, following up the two higher classes. Wages range from 40 cents to $2 a day and the pay increases according to the earning power, regardless of the time the student has served. The ages of the present students are from 12 to 31 years. The school has been in existence over a year, and, according to the speaker, is prospering. As indicating the work done the following items of a two days’ heat, March 11 and 12, 1907, were given: being Six wind boxes for the Tennessee Copper Company. Two screw frames for gang saws, movable worm Forty journal bearings for marble trucks. Nine 20-in. driving wheel centers for locomotives. Five 22-in. driving wheel centers for locomotives. One 40-in. driving wheel center for locomotives. Two sections, troughs, for rubbing bed. One large sand pump base. One friction flange for hoisting engine. Twelve driving boxes for 8 x 14 in. locomotives. Four steam chests. Four covers for rubbing bed troughs. Five valves for steam brake. One pedestal for sand pump. In addition to the items enumerated, two 8-in. x 14-in. locomotive cylinders were molded and placed in the core oven subsequently cored up and cast the following heat. THE IRON AGE 1037 The result of the heats referred to was as follows: Good castings, 8940 Ib.; bad casting, 60 lb.; remelt, 600 Ib. To- tal, 9600 lb. The total iron melted was 10,186 lb.; melt- ing loss, 586 Ib.: coke ratio, 1 to 8. The entire cost of labor for the two days was $47.10. T. R. Coggeshall, superintendent of the mechanical school of Girard College, Philadelphia, invited the mem- bers of the association to visit the foundry of that insti- tution. He referred also to the blacksmith shop, plumb- ing department and other industrial features of the training given at Girard College. Mr. Coggeshall was accompanied by a dozen of his students who were well received by the convention. Prof. William C. Stimpson made use of lantern slides in giving an account of the training in foundry work at Pratt Institute, Brooklyn, N. Y. The Pratt school is not a true trade school attempt to turn out journeymen mechanics. On the other hand it is quite removed from the engineering schools of college grade. The aim is to give instruction which will prepare men to rise to the positions of master mechanic, foreman or assistant superintendent after they have had sufficient practical experience. Pratt Institute is now carrying on work in 60 courses in which altogether there is an en- rollment of between 3600 and 8700 students drawn from nearly every State in the Union. The time devoted to foundry work is limited. The whole course in steam and machine design, as the mechanical course is known, re- quires two years. The speaker went into details as to the methods of foundry instruction and gave views of the foundry and the various operations therein, also of a group of small castings which had been turned out. In the school year of 1905-6 23 heats had been poured in the foundry. The total weight of iron charged was 27,800 lb, and the loss of metal 10 per cent. The total weight of good castings was 15,400 Ib. and of poor cast- ings 1500 Ib. In the school year 1906-7 up to April 1, 15 heats had been poured. The total weight of iron charged was 19,700 Ib. and the loss of metal was 8 per cent. of the iron charged. The total weight of good castings was 11,300 lb. and of poor castings 1000 Ib. Practically none of the labor saving machinery found in modern shops is used. The men are in the foundry school but a short time and the desire is to help them acquire as much skill in molding as possible and some insight into practical foundry conditions. The speaker believed that all the instruction given in pattern making, forging and ma- chine work, to say nothing of mechanical drafting, math- ematies, practical mechanies and power plant operation is of great value. He questioned if a single one of these subjects would be omitted if a foundry course were be ing planned. and does not was E. A. Johnson, who has charge of the foundry school of the Winona Technical School, Indianapolis, told of the work carried on there and illustrated his talk with lan- tern slide views of the foundry operations of various castings turned out. Starting last year with two boys the foundry school had now upward of 20 students en- rolled. H. F. J. Porter, New York, spoke briefly on “ Indus- trial Betterment,’ and presented a number of lantern slides illustrating progress made in the improvement of shop conditions in the various industries in all parts of the country. Mr. Porter’s paper on “ Cost Accounts,” also scheduled for the Wednesday afternoon session, was read by title. J. S. Sterling, Wilmington, Del., in the absence of H. D. Miles, Buffalo, presented a form of blank recom- mended by the Jobbing Founders’ Association and pre- pared by the Costs Committee of that association. The form submitted is for the proper keeping of the items of cost of work passing through the shop. It was presented originally at a meeting of the Pittsburgh Foundrymen’s Association, as already reported in these columns. A paper on by John H. Shaw, New Haven, Conn., was read by Van Buren Lamb, Key- stone Brake Shoe Company, New York. The company represented by the latter employs iron molds in the pro- A specimen mold was shown by ‘Sandless Castings,” duction of brake shoes. Mr. Lamb. The Universal Molding Machine, The concluding paper of the afternoon was that of E. Roneeray, Paris, France, on “The Universal System of Machine Molding.” The universal machine is so called because the same machine does both flat and intricate work. It is for the latter that the machine is particularly intended, and molds are made with or without the use of stripping plates. The saving on hand molding increases with the intricacy of the castings. The basic idea of the universal system is the making of pattern plates in the foundry without help from the machine shop. M. Ron- ceray’s paper will be presented in an early issue of The fron Age. The lantern slides given in connection with it and the cinematograph views were an exceedingly clever and interesting feature. They gave a particularly vivid idea of the rapidity with which work is done on the uni- versal machine, particularly with the swinging machine when equipped with an automatie sand distributer. One thing about the work illustrated was the extensive use of loose parts on stripping plates which is possible with the universal machine. The molding of intricate castings, as for example, aluminum work for automobiles, is one of the surprising achievements illustrated. In connection with one of his cinematograph views the speaker, after a particularly rapid piece of mold making had been fin- ished, introduced a moving picture of a molder, who, viewing the performance of the machine, threw away his tools and bowed himself out as thereafter a superfluous foundry factor. THURSDAY MORNING, Those interested in the proposed organization of the brass foundry interests occupied the assembly room at the Second Regiment Armory for the first session of Thursday morning. The committee appointed on Tues- day with Dr. Moldenke as chairman reported a constitu- tion and by-laws patterned very clesely after those of the American Foundrymen’s Association. It was decided to call the new organization the American Brass Founders’ Association. This met with some objection from the aluminum and other interests, but the difficulty of find- ing a name which would be all inclusive was appreciated, as well as the fact that the brass foundries had been the important factor in the promotion of the new association. It was explained that the intention was to bring into this association all industries whose products are made from the nonferrous metals. Those eligible to membership are not only proprietors, superintendents and foremen of brass foundries, but also all connected with aluminum, copper and other works employing sheet metal, wire or other forms of such metals apart from castings. Electro- plating interests are also included. Officers of the American Brass Founders? Association. The Committee on Nomination of Officers reported the following list of officers and the persons named were elected : President, Charles J. Caley, Russell & Erwin Mfg. Company, New Britain, Conn. Vice-Presidents: New England—W. R. Webster. Bridgeport Brass Company, Bridgeport, Conn., and W. S. Allen, Yale & Towne Mfg. Company, Stamford, Conn. New York and New Jersey—A. Bate, Nathan Mfg. Com- pany, New York. Pennsylvania, Maryland and Delaware —G. W. Wright, Reading Hardware Company, Reading, Pa. Central States—William M. Corse, Detroit Lubri- cator Company, Detroit.
