Fans E Il Established 1855 RON AGE New York, July 10, 1913 Vol. 92: No. 2 A Complete Elevator Manufacturing Plant Combination of the Roof with Sawtooth lated An unusually complete manufacturing plant has just wen completed at Honesdale, Pa., for the Gurney Electri: Elevator Company. This company was formed in 1905, when H. F, Gurney, the president, purchased the business and plant of the National Elevator Company, which had been manufacturing electric elevators since 1895. Since this reorganization, the business of the company has steadily grown so that increased manufacturing facilities became necessary, resulting in the erection of an entirely new plant. The general type of construction is steel frame, brick curtain walls, monitor and sawtooth roofs, with steel sash throughout. As the site is situated adjacent to the right-of-way of the Delaware & Hudson Railroad, sidings enter the property and give direct connection with not only the Delaware & Hudson, but also with the Erie Railroad, which operates over the Delaware & Hudson tracks at this point. The product of the company consists of electric elevators for both passenger and freight service. As it manufactures practically every part of the elevator equip- ments, it was necessary to provide for the following departments :—Gray-iron and brass foundries, pattern shop and pattern storage, light and heavy machine shops, woodworking shop and dry kiln, forge shop, structural shop, electrical department, assembling and shipping dé partments. These diversified classes of manufacture make the plant unusually complete and of more than ordinary interest. In order to appreciate the layout shown in Fig. 1, from the standpoint of plant efficiency, it is necessary to under- stand the routing of material in a general way. Raw materials for the foundry are received on the siding located to the west of the plant, and stored either in bins or piles in the yard between this siding and the foundry, where there is a jib crane installed to facilitate handling. Standard Monitor Construction—Iso- Fireproof Pattern Storage Vaults Chis jib crane is also used in handling heavy flasks, which are stored in the yard to the south of the foundry and andled on industrial cars. From the foundry, the castings go to the cleaning and storage department which occupies the north end of the foundry building lhe heavy castings travel in an uninterrupted straight hne from the foundry to the ing platform, all the ipp! erations being performed on them in high bays served These « 1 by 10-ton traveling cranes the central bay of the foundry and end of the same bay. From the casting cleaning depart- ment they go to the heavy machine bay which is practically a continuation of the high bay ot the foundry and houses the assembly and shipping departments. The light machine shop located in the sawtooth section to the east of the high bay receives castings from the storage department and delivers to either the storcroom or the assembling department sawtooth roof, draws from the storeroom and delivers to either the assembling department or astings are poured in leaned in the nortl The electrical department, also under the the storage and shipping departments.

Lumber is stored between the siding and the building, from which point it is taken either directly to the woodworking shop or to the dry kiln located south of this department and adjacent to the boiler room. Worked material from the woodworking shop is delivered to the assembling department. In the same way the forge and structural shops which occupy the remainder of this bay receive raw material on the same siding and store it in the yard between this siding and the building.

From the above description, it will be seen general course of travel is for the heavier castin: 1 I gress in a straight line in high bays served by 1 through the foundry, machine and assembling shops to the shipping department. The other departments located both sides of this high bay feed the finished parts into it all coming together at the assembling floor. This layout was determined after a very careful study of the ments of each department had been made with a view to handling minimizing the length of travel and labor of Skewe ves - July 10, 1913 f materials during the process of manufacture. Through- out the work the probable future requirements were taken into account fully [he foundry building is of regular monitor roof con- struction with one central bay served by Io-ton traveling cranes and sidebays on both sides. It will be seen by referring to the layout, that this building also houses the brass foundry, the core making, the casting cleaning and the foundry service departments. Fig. 2 is an interior view of the foundry looking south. In the right corner can be seen the cupola and charging platform. The spout of the cupola extends well out into the main bay, so that it dis charges directly into a large ladle that is located under the main crane. Just north of the cupola in the same side bay is located the core making department, the core ovens being built into the sidebay and fired from the outside Above this core making room there is a gallery which is utilized for the storage of finished cores. The blank wall at the right-hand side of the picture separates the pattern storage vaults from the foundry. The vaults are divided into five separate fireproof chambers, which open only on the outside as shown in Fig. 3. By distributing these patterns in five separate vaults, the fire hazard is, of course, lessened and the inconvenience is increased only ery slightly as those patterns which are in most constant use are stored in the vaults nearest to the door leading into the foundry. \n interior view of the foundry looking north is given in Fig. 4. The north end of this building is used for the cleaning and storage of castings, access to the high bay of the machine shop being gained through the fire door shown in the background. The sidebay, shown at the right-hand side.of the picture in the foreground, is the brass foundry, and the melting pots and chimney can be seen at the north end of this department next to the par- tition which divides the foundry service department from he balance of the building. \ portion of the interior of the foundry service room shown in Fig. 5.

There is another service room for the balance if the shop of the same general character but which does not contain any shower baths. The service rooms are kept locked during working hours and are entirely independent of the toilets which are located at convenient points throughout the plant The main shop consists of one bay 50 ft. wide and 23 ft. high under the truss.

This Portion of the Plant Has a Sawtooth Roof Re s* a a iad rm oe , at ms 7 uly 10, 1913 A Recent Automatic Rotary Engine \ new type of automatic rotary engine, for which the ‘ial features of compactness, absence of vibration and y maintenance cost are claimed, has been developed the Augustine Automatic Rotary Engine Company, 1862 mwood avenue, Buffalo, N. Y. These engines are built a number of different sizes from 5 up to 150 hp., and, if esired, larger sizes can be built to order. They are de- ened for direct connection to electric generators, cen- fugal pumps, fans and blowers, etc., as well as for work machine shops and manufacturing plants. Some of the er units are installed on separate foundations, the con- n being made through a flexible coupling. Fig. 1 is in exterior view of the engine, while a view of the rotor, howing the sliding piston blades which are the special feature of the engine, is given in Fig. 2. [he rotating portion of the engine is made up of a ylindrical piston, A, Fig. 2, which carries the sliding lades B that move in and out on roller bearings in slots n the flanges. These blades are guided by arms, which ear in bronze bushings in the compensating balance rings. The flanges in which the sliding blades move are bolted fast to the pistons and have the telescopic disks C bolted them. These disks set over the abutment, which is placed inside of the cylinder and in which the rotor moves. lhe piston, which is mounted in the abutment eccentrically with reference to the abutment bore, provides the means for the expansive working of the steam which is admitted through the pipe shown in the lower portion of Fig. 1. A Corliss type valve operated by a rocker arm and eccen- tric controls the admission of the steam, the position of the eccentric being regulated by an inertia shaft governor. [he piston makes contact with the abutment on the prim- ng pockets and is held there by the ring bearings, in which the shaft runs. As the blade passes the admission ports, which are located on one side of the central line of the bottom of the abutment, the admission valve is opened wide and steam is admitted behind the blade, forcing the piston forward until cut-off occurs, the exact point being controlled by the governor according to the load that is being carried. The steam then expands behind the blade, forcing the pistons forward until it reaches the exhaust port on the opposite side of the abutment when release occurs. The entire rotating member is carried on a shaft which runs in ring bearings located centrally with refer- ence to the outer casing. The compensating balance rings re so arranged as to balance the centrifugal force of the lades, thus keeping the rotor steady at all times and mov- ng the blades in and out of the grooves of the flanges so that they are kept bearing against the cylinder walls at all times with a packing strip along the edge to make a steam-tight joint. Pressure is equalized between the cylinder and the in- ide of the telescopic disks C, through a series of small ports in the abutment and small check valves. The pock- ets on the outer periphery of the abutment are thus filled all times with steam of the same pressure as that in the cylinder and this bearing against the inside of the telescopic disks gives a floating bearing. In the automatic lubricating system which is used, oil forced out through the pressure equalizing ports by entrifugal force and lubricates the running joint between e telescopic disks and the ribs on the abutment. The ends of these disks make a tongue and groove joint with he central rib running around the abutment, thus pre- g. 1—Exterior View of the Augustine Automatic Rotary Engine THE IRON AGE 7i Fig. 2—View of the Rotor Showing the Sliding Piston Blades venting leakage The flanges bear against the ends of the abutment, making a running joint with packing rings he piston, therefore, rotates inside the abutment, the flanges rotate against the ends of the abutment and the telescopic disks rotate in the space at the end of the abut ment. The endwise pressure is taken by the flanges which bear against the telescopic disks so that no pressure comes against the heads. As the steam is swept from the admis sion port around to the exhaust port without reversal, the result is a uniflow effect and the exhaust steam is not carried backward over the cylinder surfaces In a recent test made of one of these engines which was rated at 41 b.hp., with steam at 100-lb. boiler pres sure, 36% Il yf steam per brake horsepower hour was 1 i ver-all dimensions of this engine were length, 48 in.; diameter of casing, 17 in.. and hight, 20 in onsumed. The The Keokuk Power Plant in Operation Immediately following an automobile tour of a consid erable number of officials of Stone & Webster, along th route of the high power line from Keokuk, Iowa, to St Louis, the power developed by the new hydroelectric plant at Keokuk was turned on at midnight on Monday, June 30 ind 20,000 hp. of electricity began to be delivered to the St Louis customers of the Mississippi River Power Company Following tests with this power, gradual increase began to ward the delivery of 70,000 hp. per day with a to per cent additional load available for the peak periods of the day The inspection of the transmission line was participated in, among others, by Charles E. Webster and Harry S. Sawyer The power was turned on by Chief Engineer Hugh L Cooper, who has been in charge of the construction work. The St. Louis customers are the Union Electric Light & Power Company and the United Railways Company, the former taking a little more than half the total. The in- auguration of the service was without ceremony, this being reserved until the time when the full amount of the con- tracted St. Louis power shall be in service. St. Louis thus becomes the largest city in the country to be served by hydroelectric power, which is received at 1 sub-station on the western border of the city hav ing a capacity for handling 100,000 hp. An interesting feature of the occurrence is that the completion of the work, ready to fulfil the contracts with the St. Louis con- sumers, was on schedule time. The Keokuk plant has an ultimate capacity of more than 300,000 hp. The beginning of the new service was accomplished without a hitch of any sort, and during a very severe electrical storm July 2, there was not the slightest interference. The Alleghany Ore & Iron Company, Iron Gate, Va., blew out its Iron Gate furnace June 30 for relining and general repairs. While this work was not imperative, ad- vantage is taken of the present lull in the iron market with the view of having the stack in first-class shape for better market conditions. a 1 “e” eee a > ge te eve i i a ee el er - <a se - ee Speers Prete ote igs --e) ein? es Ve oo ne ee et ie -angrr — Teed on we ht ~~ rine eee rT Fe on The Mechanical Engineers in Germany Features of the Sessions for Papers at Leipzig, the Ocean Voyage and the Land Excursions Scientific (Staff Correspondence) Leiezic, GERMANY, June 23, 1913.—The members cf the American Society of Mechanical Engineers who are par- ticipating in the journey through industrial Germany have found very busy times since landing at Cuxhaven, at the mouth of the Elbe, in the evening of Thursday, June 10. Today were held the opening exercises of the joint meeting with the Society of German Engineers in the presence of King Frederich August of Saxony, and among the guests of honor was Count Zeppelin, two of whose air- ships moved majestically over the special train of the \mericans yesterday, Sunday, as Leipzig was approached. In fact, things which would ordinarily be regarded as unusual are becoming commonplaces. For example, as members of the American party were being guided to their hotel quarters yesterday about 5 o'clock in the afternoon, the Zeppelins continued their steady, easy flights over the city, and to add further to the interest a bird-like mono plane passed overhead high in the sky. The American party first saw a Zeppelin, however, in Hamburg, on Sat urday. The Humanizing of Labor Advocated in the Keynote Address The general meeting of the Verein Deutscher In genieure, the 54th, is largely attended. There are easily 600 of the membership present, many attended by members of their families; and 1000 is a low estimate of all interested, including those from the United States. The main paper so far presented is one by Geheimer Hofrat Prof. Lamprecht, Leipzig, on “Technics and Culture of the Present Day.” In this connection it may be mentioned as an example of the forethought shown everywhere fot the convenience of the visitors that printed copies of this address in English were distributed, while for the Ger- man-speaking participants, a companion paper, which had been arranged for, submitted by Dr. W. F. M rector of the school of engineering of the University of Illinois, was printed in German. Dr. Lamprecht’s dress was pitched on a high plane. He showed that “technics.” as the translator brought over into English the term which the speaker linked up with “culture,” has now developed from its first phase, “the mere naturalistic motive,” and has reached the second phase, that of “ideal- istic achievement.” He quoted from the preface to the latest book of the Crown Prince of Germany the statement that “since the last great war Germany has passed through a period of economic growth which has something almost alarming in it. The welfare of the people in all classes has improved to such an extent that the demand for social position and luxury has enormously increased. That much good is derived from such a high standard of economic progress should certainly not be ungratefully disregarded. Nevertheless the more somber side of this rapid develop- ment is often painfully and threateningly obvious. ie Everything is sacrificed in the eager struggle for money Old ideals and even the prestige and honor of the nation may be involved.” In the same connection Dr. Lamprecht quoted President Wilson’s inaugural address the references to American industrial achievements and the failure of the American people “to count the human cost, the cost of lives snuffed out, of energies overtaxed and broken, the fearful physical and spiritual cost to the men and women and children upon whom the dead weight and burden of it all has fallen piteously the years through.” In conclusion Dr Lamprecht said: “From a mere consciousness of the inefficiency of our economic and social conditions, we must arrive at a more exact definition of the present evils, and proceed to active measures for their removal; and here is the point at which today technics will assert itself; the ideal technics of the future. It is in the development of technics and modern industry themselves that we must look for an expedient for removing the moral and social evils which have been Goss. di ad- trom Management a Leading Topic called forth through a brilliant material progress. N: superficial suppression of these evils, no administration o charity, no theories, no political revolution, can have any lasting effect in attaining this end, but only the moral self purification of industrial development in itself, and that change to idealism, which must be accomplished in an from the further development particularly of technics. “This, then, being the state of affairs, and our positior in relation to the oppressive social evils of our time nor being hopeless, it is upon you, gentlemen, that an extremely important task of the present, and one which will certainly continue into the fairly remote future, will devolve. The nature of this task may be expressed in a few words—th: humanizing of modern labor, that quantitative productiotr may be transformed into qualitative production. An in creasing improvement in the moral relations of the tw: great classes necessary to enterprise, the employers who di rect, and the reconciliation and humanizing of the advancing social classes generally; the evolution o! a nobler society and a nobler state, would then, were they not alone consequent upon, be, nevertheless, a principal result arising out of a movement whose accomplishment rests in your hands.” Dr. Goss’s paper was read by Past-President Jesse M Smith, the author finding it necessary to remain in IIlinois [It was given nearly in full in The Jron Age of June 26.— Eprror. | workers; a Features of the Opening Session Early in the opening exercises, which were held in the Central Theater, the American Society was presented with a framed bronze tablet George Westinghouse medal, the highest Deutscher from the German Society, and was presented with the Grashof honor in the gift of the Verein Dr. Oscar von Miller, Munich, president, opened the first session, and the thoroughly filled theater presented a striking appearance. On the stage was the presiding officer’s table with the more notable seated at it on each side of Dr. von Miller, including Count Zeppelin, Dr. Rudolph Diesel and those about to make the opening addresses. Behind them were among others Past President Col. E. D. Meier, Vice-President James Hart- ness and Secretary Calvin W. Rice of the American So- ciety. True to Continental custom the participants, filling the orchestra and the second balcony, were dressed in frock coats, while the entire first balcony was given over to the ladies save for a space in the center where the King and his suite were seated amid regal decorations. The opening speeches were made by Vitzthum von Eckstadt, minister from Saxony; by Prof. Max Foerster director of the technical high school of Dresden; by Dr. Dittrich, mayor of Leipzig; by Dr. H. Bruns, director of the University of Leipzig; and by James Hartness, president of the Jones & Lamson Company, Springfield, Vt. Mr. Hartness, to whom later the bronze tablet was entrusted as vice-president of the American Society, remarked that com- bats of warfare had now given place to combats in in- dustry, and he emphasized the thought that America honors Germany, for its successes and finds the pace urging still forward. He paid a graceful tribute to Count Zeppelin, who also made a brief speech. The session came to a close with the reading in full of the two set papers, by Dr. Lamprecht and by Dr. Goss as mentioned. Ingenieure. The Atlantic Voyage A few words may be of interest regarding the nine days spent by the so-called official party of the American Society of Mechanical Engineers which left New York on June 10 on the Victoria Luise. A programme of en- tertainment, which made life on shipboard strenuous, had been arranged and in this Prof. Arthur M. Greene, Jr.. Rensselaer Polytechnic Institute, Troy, took a large part It will included a and earned well-merited praise for his endeavors. suffice to touch on the high spots, which n and other dancing, card parties, tournaments in sports and a cabaret performance in which Miss Kate ason, Gleason Tool Works, Rochester, N. Y.; Philip Fosdick, Cincinnati, and W. T. Price, general sales engi- oil engine department, De La Vergne Machine Com- nv, New York, achieved distinction. On different nights lectures were given as follows: man history, by Henry Hess, Philadelphia; German y Prof. H. E. Clifford, electrical engineering depart- nt, Harvard University; German cities, by W. R. War- r, Warner & Swasey, Cleveland, and the German educa- nal system, by Prof. C. R. Richards, director Cooper ion, New York. These were illustrated in some cases means of lantern photographs. Frank B. Gilbreth was rominent from the outset in matters other than scientific inagement, and though chief of the ship’s police, was for few hours the defendant in a mock trial. He was ably fended by Advocate Doctor Professor L. P. Brecken- e, Yale University, against a miscellaneous assortment mflicting charges and quickly exonerated by Foreman f the Jury Walter Wood, R. D. Wood & Co., Phila- elphia, who did not seem to consider it necessary to poll jury, composed partly of alleged suffragettes. Mr. Wood, incidentally, was one of three judges to award p es in a baby contest. The Beginning of the German Tour \ few words should be said of the careful planning ich had been made in Germany for the comfort and pedition of the American visitors. When the ship stopped early on Wednesday morning, June 18, for Plymouth passengers, she was boarded by Prof. George Frasch, in charge of city technical instruction in Hamburg; Jan Molsen, director Hafen Dampfschiffahrt A.-G., Ham- ire: R. Kroebel, engineer, Hamburg, and Dr. Conrad Matschoss, who is representing the Society of German Engineers in directing the tour. An elaborate programme of entertainment and plant visits had been arranged, but much mained in respect to hotel assignments and baggage transportation and distribution, and the boarding party was accompanied by representatives of the Hamburg-American Line, which has direct dletail charge. Each participant in the tour was provided with a book of coupons for trans- portation and eating on a special corridor train put at the sal of the party, and also with triangular paper pasters ittachnent to baggage. The pasters are of about six ferent colors and are also numbered, and the handling gage and the assignment to hotels is based on this e of identification. So far it would appear that local grammes are to be furnished for guiding the visitor the city and to supply him with coupons for the tainments and these are furnished while en route in special train, together with a card giving the name of ne’s hotel where he is likely to find his trunks on arrival within an hour. It was late Thursday, June 19, when the steamer train m Cuxhaven reached Hamburg, but early next morning party had entered on its busy land tour. There was the full or real German breakfast and then a boat p around and into the numerous slips constituting the 1 of Hamburg. In the evening there was an elab- dinner given by the Hamburg section of the Society German Engineers, following a formal reception and nspection of the Rathaus, a municipal building of great lendor. On Saturday there were an inspection of the Ibe tunnel; a visit to the shops and shipyards of Blohm Voss, where a luncheon not soon to be forgotten was rved; an excursion on the Hamburg elevated railroad ystem, and a visit to the power station of the railroad, here there were further refreshments; and finally the was given the freedom of Karl Hagenbeck’s world s zoological park. Blohm & Voss report themselves ry busy and are now employing 11,000 men against 9000 year. On Sunday the party came to Leipzig, a seven- ur ride, and attended a German Sunday evening festival, given by the German Society. \ Scientific Management Discussed Letpzic, GERMANY, June 25. 1913.—The second and last ssion of the joint meeting of the Verein deutscher In- enieure and the American Society of Mechanical Engi- neers was important chiefly for the presentation of two papers on works management. One was by James M. Dodge, past president of the American Society [published THE IRON AGE 73 in The lron Age of June 26.—Epitor}] and the other by Prof. Dr. Ing. G. Schlesinger, of the Royal Technical High Schi ol of Charlottenburg. The meeting was held in one of the buildings of the Leipzig International Exhibition for architecture, hygiene, etc., on Tuesday morfiing, June 24 The papers were actively discussed by the Germans, who are thoroughly alive to the possibilities of formulated methods of industrial management, and H. L. Gantt was the principal American participant in the discussion. The general atmosphere of military discipline is counted on as a help in the case of German industrial establishments, while the absence of military rigor has been regarded usually in America as the result to a properly established management system. Entertainment Features The rest of the session was given up largely to business matters of the German Society, but in concluding this reference to the Leipzig meeting mention should be made of the entertainment features, which clearly proved how captivating is the German as a host. On the arrival of the Americans’ special train in Leipzig, there was a large receiving delegation of ladies and gentlemen, the ladies laden with beautiful bouquets for presentation individ- ually to the American ladies. This was on Sunday after- noon, June 22, and later there was a German evening of eating, mass singing, speeches and vaudeville perform- ances, not to mention a valuable souvenir given to each participant. Monday morning’s session with its formalities, partly owing to the presence of Saxon royalty, has already been mentioned. In the afternoon there was a concert in the Gewandhaus by the symphony orchestra of the famous \rthur Nikisch and in the evening a banquet in the Central Cheater, followed by a ball Tuesday afternoon was given over to simultaneous visits to industrial plants and to an inspection of the Leipzig Exhibition. On Tuesday en- ing there was a festival in the Palmengarten “ ae ; ks ; Government Investigation of Defective Wheels and Axles WAS NGTON 1). a July S Oi 3.

More details as to the S( ope of the investigation will be given out by the | reau the com- ing week. In announcing the proposed investigation Sec- retary Redfield said in part “Certain data taken from the annual report of the In- terstate Commerce Commission for the year ended June 30, 1912, giving the derailments due to defective equipment and roadway for the II years, 1902-1912, inclusive, were called to my attention and this investigation is to be the outcome. From these data it appears that the wrecks caused by broken carwheels are substantially four times as numerous as those caused by broken rails, and the wrecks arising from broken axles are one-half greater in number than those from broken rails. It would appear, therefore, that the total accidents arising from -broken wheels and axles taken together are almost six times as numerous as those arising from broken rails within the period named, and that the tendency is toward a continu- ance of this condition, especially as regards wheels.” wy. a & The Wellman-Seaver-Morgan Company, Cleveland, Ohio, was low bidder on coal-handling plants to be erected at Panama by the United States Government The con- tract, which will shortly be placed, will provide for a coal- handling plant at Cristobol on the Atlantic side, with a loading capacity of 2000 tons per hour, an unloading capa- city of 1000 tons per hour and a storage capacity of 250,000 tons. and another at Balboa on the Pacific side, which will have half the handling capacity and half the storage ca- pacity of the Cristobol plant 1 eee he ak eae % 74 THE + New Screw Making Machines Elimination of Waste Material a Feature of the Latest International Development The International Machine & Screw Company, Spring- ield, Mass., has deve'oped a group of machines for the manufacture of screws, which is the invention of George T. — es ee safle th Sagem ne ipl ety o a ee *. : i ! : ‘, } } ; i j big I cre I ing M : 4 \Varwick, its vice-president and general manager.

The five sets of dies operate in frames mounted on the housings, as shown in Fig. 2, and spaced to correspond to the positions of the chuck spindles of the turret. Their motion is imparted by toggle gears which receive their power through a lever, the other end of which is hinged to a spider, Fig. 3, and this is connected by a knuckle joint to the cam lever. The cam is so timed as to open and close the dies to conform with the movement of the turret to Fig He e M the h sing Phe es art n { cs \ ( I Il ne mn the tiie he wear is practical 1 neglig anti ( ntet lant Lite t \ el \ me I g cks arried by the next tation the limit gauge which determines its position in the di® a it is accomplished with much accuracy, beca necessary to keep the length of metal reserved thin very narrow limits.

Among re- cent shipments of its Economy turbines are four 8o0o-hp. for driving 25,000,000 gal. pumps, Chicago Water Works; an 8so hp. for similar service at Nashville, Tenn.; two turbo-pump units for the Pittsburgh Crucible Steel Com- pany; two for the Carnegie Steel Company. One of the largest pump builders in the country has ordered 16 tur- bines. Recent orders have also been received from Eng- land, Sandwich Islands and India. The company has just developed its first 500-kw. alternating-current unit and is now better prepared than ever to serve its customers with larger electrical units. 100,000 hp. of com- pany’s product is now in daily service. Over this July 10, 191: A Double-Spindle Milling Machine time by enabling both the roughing and fin ishing cuts to be taken at the one clamping of the work the Garvin Machine Company, Spring and Varick streets New York City, has equipped its No. 13 plain milling; machine with an extra spindle. The roughing spindl which has a I-in. vertical adjustment and is driven fron a separate countershaft, takes a cut before the regula finishing cut is taken with the regular spindle. The machine has the builder’s standard solid top ex tended knee with a square lock and taper gib, which doe away with any possibility of weakness of the saddle fit t the knee when heavy cuts are being taken. The saddle guide is located centrally over the in-and-out-screw, an the slide fit in the saddle is increased about 30 per cent Two taper gibs used for the slide fit, which, it is pointed out, is a marked advantage over a single one. The diameter of the table been increased and th feed screw fixed and one adjustable nut and has at the shoulder in the slide. An adjust able micrometer dial provides facilities for every kind of spacing work, locating holes, jig boring, etc. The feed-change box provides 12 positive gear changes, from the end of the spindle by a nickel-steel sprocket chain. The gears used are hardened steel and run on 12 hardened studs equally spaced around the cylinder. The feed changes are secured by turning a crank, a turn to the right increasing the rate, while mo- tion in the opposite direction decreases it in approximately progression, the range extending from 0.002 To Save are screw has has one an adjustable nut ‘utting, Tack the feed being transmitted Milling Mac! ne Equipped with an Extra Spindle Before the Cut with the Reg- for Taking a R« i] Spind'e is Taken ughing Cut r Machine to 0.08 in. per revolution of the spindle.

Alexander 10, 1913 -egrinding and Equalizing Boiler Check Valve [he application in new forms of four mechanical princi- is the special advantage claimed for the Osman regrind and pressure equalizing boiler check valve, which is manufactured by the Swenson Valve Company, rah, lowa. The various features characterizing the Sectional View Showing the Arrangement of the Principal Parts of the Osman Regrinding and Pressure Equalizing Boiler Check Valve alve are the instantaneous release, easy regrinding of the seat, the use of a combination nipple and seat, a bridge construction at the port entrance for equalizing the steam pressure and a combination union nut and ball joint at he bonnet. Che instantaneous release of the valve which sometimes mes stuck in the valve chamber by sediment or foreign matter is secured by the operation of a loosely operating divided clutch, a, which drops automatically over the valve when the stem is screwed in. This clutch acts as a solid part of the stem, and the automatic action, whether the check is shut off or is operating under full steam pressure, loes away with sticking of the valve. The seat is reground by bringing the clutch into action on the valve wings c, and screwing the stem in until the valve disk and the seat are in contact and applying the usual amount of emery or ground glass to the seat. It is pointed out that this operation can be accomplished quickly without removing the check valve or any part of it, except to loosen the combination nipple and the seat to apply the emery or the ground glass. The clutch arrangement re- quires only the use of the hand to produce a reground seat in a few minutes, and the simple act of grinding the disks and the seat together instantly removes sediment or other foreign matter. The use of a combination nipple and seat which is crewed to the check body is a new idea. In this way it is pointed out that the seat can be removed for repairs or examination without removing the body from the boiler, and as the seat is removable it can be placed in a machine and reground more accurately than if the rdinary hand method were employed. For equalizing the distribution of the steam pressure inder the disk and preventing its oscillation, a bridge, d, is located at the port entrance of the stem to the valve hamber. It is pointed out that in this way the excessive wear which occurs on the side of the disk nearest to the rt entrance of the stem to the valve chamber is elimi- nated. The application of a union nut to the bonnet end and a ball joint arrangement, e, which can be readily re- round by loosening the nut and turning the stem, is ‘nother feature of the valve. It is pointed out that this action on the ball joint will keep the union nut and thread THE IRON AGE clean and free from sediment accumulation of foreign matter, as contrasted with other types of boiler check valves in which the opening f is covered with a cap or plug, and it is not possible to overcome leaks or abrasions without dismantling the check entirely A New Type of Power Hack Sawing Machine To meet all the requirements of a metal power saw, a new hack sawing machine has been brought out by W. D Pratt, Canton, Ohi The important features of this ma chine are a quick return stroke and adjustments for chang- ing the length of the stroke and the position of the swivel vise so that either end of the blade can be used Che length of the stroke is varied from 0 to II in. by sliding the block that holds the driving arm toward or away from the center of the driving gear, as is shown in the accompanying engraving. In this way, the full length »f the 17-1n. blade can be used, the saw cutting on the outward stroke \n adjustment for the vise is provided in the sliding head so that either end of the blade can be used and emphasis is laid upon the fact that this feature will result in a great saving in blades The saw will handle work measuring 8 x Io in The saw frame is supported in a rack and is raised by hand, a catch being employed to keep it in the elevated position. When the work is measured, the catch is re leased and the saw descends by gravity feed. The wearing parts are split bushings. The ratio of the driving gears, which are cut, is 3 to I and the saw makes 50 strokes pet A Power Hack Sawing Machine with a Special Type of Quick Return ind Stroke Adjustment min. The driving pulley, which is 12 in. in diameter with a 2-in. face, operates at 150 r.p.m. The base occupies a floor space of 12.x 27 in. The weight of the machine is 180 Ib. The Titan Copper Products Company, recently incor- porated, will operate a plant in Buffalo, N. Y., for the manufacture of brass, bronze and aluminum castings. Charles V. Slocum, who will be president of the company, states that in placing on the market in the past six years a well-known deoxidizer he became much impressed with the apparent need in the non-ferrous metal trade of well deoxidized castings. Applications for patents have been made covering certain new ideas and processes. Frank P. Lund, who is among the best-known makers of high- grade castings, will be general superintendent; A. N. Slocum will be vice-president, and W. W. Slocum, treasurer. The Massillon Rolling Mill Company, Massillon, Ohio, maker of special sheets, is considering the erection of a large e
