IRON AGE The Munton Process of Manu- facturing Steel Tires, | With Supplementary Sheet of Engravings. | The Chicago Tire and Spring Company, whose works are at Melrose, near Chicago, Ill., have built and had in successful oper- ation for some time a plant for the manu- facture of locomotive and car wheel tires and circular forgings which, in its method of treating steel, is a marked departure. James Munton, the superintendent, is the inventor of the new process and of the machinery for operating it. Throughout the whole process Mr. Munton has avoided, of the hammer is detrimental to the steel for these purposes. Much more detrimen- tal must hammering be to a tire ingot which is beaten upon its end and the diameter thereof increased some ten or fif- teen inches, for which work manufacturers are now using upto twenty ton hammers, in order to do the work with the greatest rapidity. The tread of the tire must con- sequently be damaged, while the steel is densified or benefited on the inner portion of the tire where there is no wear. In Mr. Munton’s process he avoids the use of the hammer altogether, and in elongating the ingot, or bloom, into a tire he densifies the metal on the tread and increases the wear resisting properties of the steel. By way of preface to a detailed de- as far as possible, everything in the treat-| scription of the new process it may be well at the top. The subjoined illustration, Fig. 5, shows a cross section of an ingot as first cast, before slitting. The casting of this ingot is a simple process, requiring no skilled labor. The ingot being thin radially, the interior cools much sooner than if it were solid, and the steel is therefore more dense, be- cause the annular ingot cools from the in- side as well as the outside, thus causing it to be more uniform‘and preventing liqua- tion. The illustration, Fig. 6, shows a two-tire ingot partially slit, and also in- dicates the method by which the slitting is done. At present the ingot is slit in the same mill which is used for finishing the tires. In slitting, two upright rolls are used. One roll operates upon the inside of the THE MUNTON PROCESS OF MANUFACTURING ment of the steel which would tend to in-}to give a brief summary of the several jure either its character or the quality of the finished tire. The ordinary method of manufacturing tires is to cast a solid ingot of cylindrical shape, which is then heated and upset under a steam hammer until its hight is reduced and its diameterenlarged. After a hole has been punched in its center the ingot is then placed on a beak or pike horn and hammered by blows struck on the periphery. It is then again heated and placed in a rolling mill and rolled into a tire of the required diameter. In his determination to improve upon old methods, Mr. Munton began at the root. He reasoned that to hammer a steel ingot down from say 18 inches in hight to 6 inches, and thus increase its diameter, was essentially wrong in principle, as the metal so tortured must stretch at the out- side or periphery, thus tearing it apart more or less and producing cracks and strains. The Iron and Steel Institute of Great Britain has discussed thoroughly the effect of hammering steel for plates and shafts with the verdict-that the violence steps taken, which are as follows: 1. The ingot is cast with a hole cored out large enough to admit a small roll. 2. The ingot is heated and taken to the ‘rolling mill, where its top, with its im- | perfections, is sheared off and the bloom left of a given weight. At the same heat }and by the same operation the bloom is also roughed out by the roughing rolls of |the mill and edged down by horizontal | rolls. 3. The bloom is reheated and placed in the tire rolling mill, where it is rolled and finished to the exact inside and outside diameter required. Proceeding to details, the ingot will be first considered. Mr. Munton’s present | practice is to cast an ingot large enough for two or more tire blooms. He uses a collapsible steel core which he has in- vented.. The steel is produced in an open hearth furnace and poured from a ladle into the molds over a spreader of circular form which covers the core and causes the steel to flow down on all sides, keeping any dirt in it flowing and thus collecting 149042 STEEL TIRES. ingot, as shown above, while the other roll operates on the outside. The outside roll is driven. It has a sharply beveled edge as a top cutter, a projecting flange as a central cutter, and a bottom flange to support the base of the ingot. Grooves are formed in this roll at suitable places to partly shape the tread of the tires. The flanges all extend the same distance out- ward from the roll. The inside roll has projecting flanges to correspond with those on the outside roll, but shorter. An illus- tration is givenin Fig.7 of an ingot after the top has been sheared off and the remainder cut into tire blooms ready for finishing. It will be seen that by this process blooms for tires or rings are manufactured very rapidly and therefore cheaply. The roughing done during the slitting process greatly assists the subsequent finishing. Mr. Munton has, however, patented im- provements on this process by which two or more tires can be slit, roughed and finished at the same heat by using a separate finishing mill in conjunction with the slitting and roughing mill, or four tires could be finished at a single heat by -522 THE IRON AGE, October 2, 1890 using two finishing mills in conjunction] used for rolling tires or rin with one slitting and roughing mill. Tires made in this manner would be in absolute pairs, which is of prime impor- tance. This advance in the art makes the process a continuous one analogous to the continuous process of making rails, the original melting heat of the ingot ‘being utilized throughout the entire oper- ation. The removal of the top sedimentary portion of the ingot, as above described, will be recognized by all steel workers as a very valuable point. One of the most important features of ‘this process is the slitting of the ingots, ‘which operation is so economical, bene- ficial and original in its conception that Mr. Munton was granted a process patent on this alone. As an illustration of what can be done, Mr. Munton states: ‘‘ We have slit fourteen ingots into 42 blooms in one hour on our present mill which was not originally designed for slitting.” These blooms were for small tires with in- ternal flanges for electric motors. ; of any sec- tion and diameter up to eight feet and rings up to 16 inches wide. The vertical exterior pressure or slitting roll and the lower edging roll are driven by steam power. The engine has no fly- wheels, being built on the reversing prin- ciple so as to start or stop quickly. The ° ui iy Ct 71 \a Pe al GE ll , rf i Ey tL i Wl ear 4 TSS a m — XS Fig. 4.—Side Elevation, Showing Mill Engaged in Rolling a A perspective view of the present mill is given on our front page. It consists of an exterior fixed vertical pressure roll (which also operates as the slitter); a vertical inner pressure roll, with horizontal movement; two vertical guide rolls with horizontal movement ; two vertical exterior pressure rolls with horizontal movement; and two horizontal or edging rolls, one above and the other below the bloom operated upon. The upper edging roll is moved vertically by the edging cylinder. - This mill is a universal mill which can be THE MUNTON TIRE MILL. movable rolls are operated by hydraulic power, controlled by valves shown in the foreground of the perspective view. Thus the edging, interior or exterior rolls may either or all be brought into play upon the tire whenever desired, either simultane- ously or one set at a time, so that the sec- tion of the tire, its size and diameter, are always under the complete control of the operator and can be instantly changed as desired. Ifthe tire, through any accident, happens to be rolled of too large a diam- eter, it can be quickly rolled back to the t rf az I id D | MU a SS liibiiabek: mn aR ETAT titi proper size. Further, if the bloom, after shearing and roughing, contains defects which require to be cut out, producing notches, the bloom can he rolled back to a smaller diameter and the defects caused to disappear, after which the tire can be rolled out to the proper diameter again. In rolling back to asmaller diameter, only the exterior and edging rolls are used, no in- ternal pressure being applied, as that would defeat the purpose in view. The rolls are so arranged that all four sides of the tire in rolling out are covered, so that the metal cannot burst under the operation, as is possible with a hammered tire where only two opposite sides can be covered or operated upon at once. When the tire is being rolled back by the exterior pressure rolls and simultaneously operated upon by the edging rolls, it is reduced in diameter and the metal is crowded together and densified on the tread which is upset in the proper direction to promote its wear- ing qualities. Any desired amount of den- sification or work can be put upon the tire by rolling the tire outwards against the i i ncelineemenel | 1 LLNS WW Oy SAWN Sia \ Pair of Tires. pressure of the exterior rolls, which press- ure is varied as required. Thus it will be seen that the tire is given very great den- sity, and that the steel can be forced into any required section, both on the tread and on the interior of the tire, even to the ex- tent of forming a wide internal flange. The method of operating and govern- ing the various rolls employed will be better understood by the help of the de- tailed drawings herewith reproduced from plans prepared by Charles Quast, me- chanical engineer of the company, for the October 2, 1890 THE IRON AGE. 523 new mill now in process of construction. The first, Fig. 2, is a side elevation of the mill, showingits full length, The top ofthe bed plate is on the ground level and the machinery below it is therefore all under ground. The mill, as shown here, is en- gaged in slitting an ingot large enough to make fourtires or two pairs. The next view, Fig. 4, shows the same mill engaged in en a pair of tires. The high massive framework extending above the general level of the mill isa slide operated by hydraulic power, which moves it back and forth on the bed plate. This slide carries the top and bottom edging roll and two vertical pressure rolls. A sep- arate hydraulic cylinder is placed in the upper end of the slide to operate the movements of the edging roll. So com- pletely has this roll been supplied with actuating machinery that it is capable of Fig. 5.—Cross Section of Ingot as First Cast. being placed in almost any position. It will operate as a piston and advance or recede; it can be elevated or depressed ; it can roll on a perfect level or at any bevel. The two vertical pressure rolls change their position and move to or from each other as may be required in rolling a tire. Connected with the slide by means of cams, levers and pivoted links are the vertical guide rolls on each side of the main exterior driven roll. These guide rolls thus automatically change their posi- tion in harmony with the two vertical pressure rolls attached to the slide, ad- vancing and receding as the tire is rolled larger or smaller, but always moving in such perfect accord with the other rolls that the tire preserves a true cir- cular form. The connection of these rolls with the slide is best shown in the plan view of the mill, Fig. 8. An ingenious device operated in connection with the slide is an index which describes an arc of a circle and points to the diameter attained by the tire then being rolled. This is a valuable aid to securing accuracy. The inside pressure roll is adjusted by a hydraulic cylinder which extends under the bed- plate back of the main exterior roll. When two or more rings or tires are being rolled the inside pressure roll would not be suf- ficiently rigid to endure the strain with- out a top support. The slide which carries this roll is therefore provided with a swinging hanger furnished with a box or bearing for the upper end of the roll. This hanger will raise and turn back out of the way automatically when the blooms or rings are being placed in or taken out of the machine. It will be seen from the above descrip- tion of this mill that it is so largely auto- matic that very few men are required to operate it. This has been the case from the beginning, but even fewer men are now needed than then, by reason of im- provements which suggested themselves as the mill became susceptible of closer study in practical operation. The saving in time and labor by this process employed by the Chicago Tire and Spring Company, is estimated at 30 per cent., as compared with the old method. As the tires are claimed to be much better, because the steel has not been tortured by hammering, the Munton Mill certainly appears to have great @) vantages over the old system. Mr. Munton has taken out patents on his mill and process in Great Britain, Ger- many, Italy, France, Austria, Belgium, Russia, Norway and Sweden. The magnitude of the new mill will be readily seen from the following dimen- sions: Its entire length will be 80 feet; its hight, 44 feet—20 feet below and 24 feet above the level of the ground; its width, 21 feet; its calculated weight 891 tons. The bed plate will be built in six sect’ons, with a whole length of 54 feet 10 inches and weight of 126 tons. The inside pres- sure cylinder will be 20 inches in diameter ; its weight 12 tons. The edging cylinder will be 20 inches in diameter; its weight 8 tons. All the cylinders will be con- structed to carry 5000 pounds hydraulic pressure per square inch. The power required for the operation of the mill will be furnished by a pair of compound condensing engines developing 2000 horse-power at 80 revolutions per minute with an initial pressure of 100 pounds ; the diameter of the high pressure cylinder is 28 inches and of the low pressure cylinders 47 inches by 48 inches stroke. The engine. shaft will be connected with the 17-inch main driving shaft, which carries a helical spur wheel of 71 inches diameter and 20 inches face, which matches on the top with a 63-inch helical spur wheel to drive the 12-inch bottom edging shaft at 90 revolutions a minute. The 71-inch spur wheel also matches into a 98-inch wheel below it to drive the 134 inch bottom driving shaft, at 60 revolu- tions a minute and this shaft, through a pair of miter gear wheels of 60-inches dia- meter, drives the vertical exterior pressure shaft of 164-inches diameter. This millis designed to slib and bloom ingots for four tires simultaneously and to roll tires or rings of any section and di- ameter up to 12 feet or for rolling plain steel bands for any purpose required, such as boiler shells, gun rings, &c., ranging from JM: “KI NAGATA) fil Yy, — on > yy Va A Ti WY Uy 2 B te ; a) machinery, $1,636,000. The Tiehouart, Bouvines, Jemmapes and Valmy are the names of four others of the new cruisers, The first-named is being built by the Gov- ernment at an estimated cost of $2,780,000, and the others are being constructed at private contract. As regards the hull the four vessels are identical, and each will have a displacement of 7000 tons. The Trehouart will be supplied with the Belle- ville tubulous boilers, and the others will a i y acai Yl Fig. 7.—Ingot After Top Has Been Sheared Offand Remainder Cut Into Tire Blooms, Ml be furnished with multitubular boilers with the return flame system. The ex- pected speed of each of these vessels, at natural draft, is 16 knots, with the en- gines making 100 revolutions a minute. The water line is to be armor clad from one end to the other. Their hulls are to be of the Martin-Siemens steel, and the: stem and stern are to be of cast steel. Each will be armed with two 13-inch 'guns, four 4-inch quick firing guns, four | guns of 47 mm. (a little less than 2 inches |in diameter), ten Hotchkiss guns of 37 mm. and two torpedo throwers. | There was launched from Cramp’s yard, ‘in Philadelphia, on Saturday, the freight |steamship El Sol, the largest of her class | in the coastwise trade.

They are expected to make a 17-knot speed with about 6600 horse-power under natural draft, and 19 knots under forced draft and 8200 horse- power. The coal supply at normal dis- placement will give a radius of action, at 10 knots s , of 4000 knots, or just about the same as the capacity of the cruiser Baltimore, of the United States Navy. The estimated cost of the first two named, inclusive of hull and machin- ery, which are being built by the French Government, at Rochefort, is $1,778,000. The contract price for the other two, being constructed by private firms, is, including will trade between New York and New Orleans. The ship is 400 feet long, 48 feet beam and 33} feet deep, and has a capacity of 4300 tons. She is schooner rigged, with four steel masts. Her power is furmshed by triple expansion surface condensing engines, with high pressure cylinders 32 inches in diameter, inter- mediate 54 inches and low pressure 84 inches, with 84-inch stroke, with a work- ing pressure of 160 pounds. She has three double-ended cylindrical steel tubular boilers, each 13 feet 10 inches in diameter and 20 feet 6 inches long, each weighing about 58 tons. Her machinery will develop 3500 horse power, and she will have a speed of 144 knots per hour. The Governor-General of Canada made an inspection of the great St. Clair tunnel and highly complimented engineer Hobson. for the skill exhibited in its construction. THE IRON AGE. October 2, 1890 The Coke Trade. The shortage of cars in the Connells- ville coke region which has existed for some time has been partially removed, and operators and furnace men are correspond- ingly happy. During the spring and sum- mer, when the coke trade was rather dull, two or three firms accumulated an im- mense stock of coke in order to be pre- for any strike or shortage that should occur. The wisdom of this plan has been fully demonstrated during the t two months. These firms had on d plenty of coke to meet the most urgent demands, while other firms were at their wits’ end to obtain sufficient coke to keep their furnaces in operation. Dur- ing last week some of the furnace operators in the Mahoning valley were almost en- tirely out of coke, and to meet their wants two special trains of 80 cars each were sent out of the Connelsville region. Had this not been done it is probable that a number of blast furnaces would have been compelled to bank down for a few days until a supply could have been obtained. The demand continues heavy and shows no signs of abatement. The shipments for the. week ending on September 20, amounted to 6619 cars, divided as follows: To Pittsburgh and river points, 1560; to points west of Pittsburgh, 3900; to points east of Connellsville, 1159. The record of the previous week was: Pittsburgh, 1620; West. 3645; East, 1090; total, 6355. The total number of active ovens in the region for the same period was 13,569 and 1905 idle ovens. The completion of 250 ovens at Leisenring No. 3, completing the 500-oven plant there, has swelled the total number of ovens owned by the H. C. Frick Coke Company to 9054 out of a total of 15,474 in the entire Connellsville region. There are no — to note in prices, which continue as follows: Fur- nace coke, $2.15; foundry coke, $2.45; crushed coke, $2.65; all per ton of 2000 pounds, f.o.b. cars.

TT — Large Refrigerating Plant. The Fred. W. Wolf Company, engineers and architects, of No. 560 North Halsted street, Chicago, and sole owners for the United States of the Linde ice machine patents, have just completed for the George F. Swift Company, at the Stock Yards, what is claimed to be the largest refrigerating plant constructtd in the world. It has a refrigerating capacity equal to the melting of 800 tons of ice daily, and to operate the machinery re- quires two 500 horse-power Corliss en- gines. It keeps their immense storage rooms at an equitable and even though ex- ceedingly chilly temperature, and is a model of engineering skill. Since Mr Wolf first introduced the Linde ice machine, in 1883, to the brew- ing, packing and other interests requirin the use of large quantities of ice or col air, they have been in all cases universally successful, but never before has been erected a machine of the size or capacity of this, which is, nevertheless, as suc- cessful in its operation as the smallest ma- chine made by them. The Linde is the only machine that can be run by belt mo- tion even in the largest sizes, and in the Swift plant there are several — four 50-ton machines run by one belt The daily capacity of the Linde ma- chines now in use represents about 35,000 tons of melting ice; those built by the Wolf Company, and now in use in the United States, representing 7500 tons. This last production is well worthy a visit from engineers and persons interested in ice and refrigerating machinery, who will find it an exceedingly interesting study. EE Wellman Iron and Steel Company. The works of this company are situated at Thurlow Station, on the ome Wilmington and Baltimore Railroad, 16 miles trom Philadelphia, Pa. The works also have the tracks of the Philadelphia and Reading Railroad running into the yard, and through this line a connection with the Baltimore and Ohio system. The property covers about 40 acres of ground, the Delaware River being on one side and the railroads on the other. Steamers of the largest size can unload at the wharf. There is one blast furnace of 17 feet bosh, 72 feet high, using foreign ores, making an iron of the best quality for the manu- facture of steel. The open hearth plant consists of two 15-ton furnaces, well equipped with hydraulic cranes, &c. The Bessemer plant consists of twe 3-ton converters, with the necessary cupolas, blowing engines, hydraulic plant, &c. The blooming mill is in connection with the Bessemer plant and is a reversing mill with 30-inch rolls. In it can be rolled 164-inch square or smaller open hearth and Bessemer ingots into blooms as small as 4-inch x 4-inch or slabs up to 16 inches wide and down to 14 inches thick. The plate mills consist of a two high train with 80-inch rolls, 80inches and 100 inches long; a 25-inch three high mill with 72- inch rolls. A larger three high mill will be added immediately. The company have also 11 double puddling furnaces for the production of puddied bar for iron plates. The officers of the new company will be as follows: 8S. T. Wellman, president; Wm. G. Neilson, vice-president; John P. Crozer, treasurer; Richard Peters, Jr., secretary. The general office of the company will be at Thurlow, Pa., with a branch office at No. 335 Walnut street, Philadelphia, Pa., a private wire connecting the two. NEW ENGLAND NOTES. The electric light and power plant at Veazie, Maine, is almost completed. Six of the im- mense water wheels have been placed in posi- tion and the pits for nine more are being con- structed. The engine in the new Auburn Stove Fac- tory, at Auburn, Maine, has just been started up for the first time and the shafting set in motion. The works will be started up in full in a few days. In Hartford, Conn., a number of citizens bave organized what they will call the Board of Trade Room and Power Company. They propose to erect a building suitable for the accommodation of a number of small manu- facturing enterprises. The building will be first class, equipped with a power plant and tools, and will be divided into as many rooms as may seem advisable. The idea is to rent these rooms to inventors or mechanics who may have undeveloped ideas relating to machinery at low rates, and to give them such otber assistance as may seem advisable, in a mechanical way. Such ideas as seem to be — will then be considered by the Board of rade, and such action taken as may be deemed advisable to place the enterprise on a proper financial footing. The Connecticut Motor Company of Plants- ville, Conn., have issued a very neat catalogue of electric motors. The catalogue sets forth the advantages of electric motors, the illustra- tions being excellent. The an of electric welding invented by Prof. Elihu Thomson, which has been so widely used in its application to numerous manufact- ures pertaining to the arts of peace, has now _ | been applied to the production of certain mu- nitions of war in a very remarkable manner.

This application of the electric welding process to e production of shells has reached very satis- factory results—entirely beyond those achieved by methods of manufacture hitherto carried on, The armor piercing point of the shell is made of hard steel shaped in a conical form suited for such a purpose ; to this is attached a tube of mild steel forming the chamber.

Th new application of the electric weld roc- ess was invented by Lieut. H. M. ood, United States Navy, who has received a year’s leave of absence from the Government and is in the meantime associated with the Thomson Electric Welding Company, of ram Mass. It is stated that the United States Government is ready to contract for a very large supply of these electric shells as soon as the machinery can be made for their manufacture. e ) October 2, 1890 THE IRON AGE. 525 Electric Power Hammer. This electrically actuated power hammer is of the reciprocating type, the part de- livering the blow being connected directly with the reciprocating piston by which the power is imparted. The piston is of magnetic material and moves within a ver- tically arranged series of coils connected in series and each being provided with a separate insulated contact. The actuating mechanism is mounted vertically in a falling in accordance with the rise and fall of the current above and below it. By mov- ing the shifting field of force to any de- sired part of the coils the position in which the piston will reciprocate can be changed at will and a blow delivered wherever de- sired—that is, the hammer can be made to strike directly on the anvil or any distance therefrom within the limit of construction. Provision is made for regulating the cur- rent passing through the coils from the points of maximum and zero electromotive FE ik iid Miikka hatadadadhtahadhgidah Aadalddaiaisd SS ELECTRIC POWER HAMMER, frame resembling that of the ordinary steam hammer. Between the lugs of the frame is placed an anvil, B, toreceivethe work. Between the guidways CC’ moves a cross-head car- rying the hammer E, and provided with a piston rod, F, which is secured to the mag- netic piston G. This piston moves verti- cally within a series of coils, H, arranged one above the other in the magnetic envel- ope A, which is a cylinder standing on to of the frame. The coils are all connect in series and each one is provided with a separate insulated contact, these being ar- ranged in the form of aflat commutator, [. During the operation of the machine the piston sy ie continually in a con- stant but changing field of force, within which it may be said to float, rising and force. Provision is also made for govern- ing the rate of reciprocation of the piston. The stroke of the piston is varied by ad- justing the brush carrier L up or down upon the commutator I, by means of the lever N, which is connected to the brush carrier by the rod n. The vertical series of coils may be made of any desired hight, in order to give the required range of action, and the brushes & spaced to in- clude two or more coils, and so to deter- mine the length of stroke of the piston.

Company was re- cently begun, and is now well under way; when in operation this concern will manufact- ure mill machinery and sawmill equipments. I A Powerful Corliss Engine. The Philadelphia Traction Company are just now making alterations in their engine stations. The alterations consist in the erection of two new Corliss engines in the Sansom street and the Twenty-third and Market street stations. The old engines, two of which are in each station, will be kept in position, so that if anything breaks about the new ones the cable can still be kept in motion. The machinery is to be so arranged that the old engines can be attachtd to the new drums. Workmen have been toiling in the Sansom street station for weeks, and it is expected that by November 1 the big engine with all its appendages will be in running order. An exact duplicate will then be put in the Twenty-third and Mar- ket streets stations. The new engine, which, like the old one, is from the shops of Robert Wetherill & Co., of Chester, is the largest one in Philadelphia. It is of 1000 horse-power, and fed by eight boilers. It isa vertical Corliss engine, 28 feet high, and the cylinder is mounted on an A frame, which is supported on the main bed casting, in which is movnted the en- ine shaft. The cylinder is 40 inches in Siesuter and the stroke is 48 inches. A winding stairway with upward of 30 steps leads from the bed casting to the top of the engine. The length of the bed casting upon which the engine stands is 18 feet long by 11 feet in width. A shaft 62 feet long and 18 inches in diameter and weighing 35 tons is set in six journals and conveys the power from the engine to the cable drums and idlers. The shaft was cast in four pieces, each 15} feet long, so as to render the handling of it easier. The journals each weigh 4} tons. The shaft extends from the engine, which is in the northwestern corner of the building, to the other end of the room, where is sta- tioned a new upright drum and append- ages. On the left side of the engine is suspended the balance wheel, 24 feet in diameter, with a square rim 15 inches wide and weighing 40 tons. The wheel was cast in ten segments. To the left of the balance wheel and in front is the spur gear wheel, to which the main shafting is attached. The gear wheel is 22 feet in diumeter and the cogs are 6} inches apart from center to center, the whole thing tip- ping the beam at 22 tons. The engine and the other machinery are built upon a foundation from 18 to 20 feet deep and made of brick grouted in the best Portland cement. Over 300,000 bricks were used in making this substantial and unyielding bed. I Hydraulic Presses and Shears Driven by Steam Intensifiers. A system of driving hydraulic shears and other presses by steam intensifiers has been developed on a large scale in Ger- many by R. M. Daclen, of Duesseldorf, the firm of L. W. Breuer, Schumacher, Ralk, near Cologne, being the manufact- urers. It is claimed that it has proved the simplest and most economical in the use of steam and the cost of installation Fig. 1.—The Daelen Shear, with Intensifier. The engine, including the bed casting, gear wheel and clutch coupling, weighs 125 tons. The other part of the new ma- chinery, including cable drums, idlers, shafting and pedestals, came from the Pennsylvania Iron Works, and, altogether, weighs 175 tons, making a total of 300 tons of machinery. The vew cable drums and idlers are different from the old, and will be in a vertical position, the idler standing above the drum. Two of these are already in place, one near the center of the room and the other at the east end. Two more of the same kind will be located on the Sansom street side. The drums and idlers are 12 feet in diameter, mounted on a heavy frame work of cast iron, and weigh 12 tons apiece, the four sets making a total of 96 tons. These wheels were put in a vertical position, as was the engine, to save ground space. The amount of room is limited, and repairs. When hydraulic power is used for ingot shears, forging and stamp- ing presses, the water pressure must be very high—up to 7000 pounds per square inch—in order to obtain cylinders of small diameter. It is difficult to maintain sueh a distribu
