It occupies a plot of ground 100 feet square fronting on Cecil alley, between Penn avenue and Duquesne way, and lies in a fairly central position with regard to the properties it is to serve. The advantages of such a cen- tral plant will be appreciated; conspicuous among them being that the basements of all other buildings are left power 1904. throughout the rest of the building the steel is covered with hollow fire proofing tile, around the columns and arched between the floor beams. These floors are then surfaced with concrete over the fire proofing. In a sim- ilar manner, the roof beams are covered with fire proofing tile and concrete, then with heavy tar paper, and surfaced with Welsh tile. The tile are of hard burned clay, such as is used for vitrified sewer pipe, and are laid upon the tar paper with flush joints filled with water proof mate- rial. The slope of the roof is about 44 inch per foot, to shed water. The first three stories are 24 feet from floor to floor. and are occupied entirely by boilers and machinery; the remainder are 13 feet in hight, and are suitable for light manufacturing, an ample supply of power in various View in Engine Room on First Floor, Showing 1000-Kw. Engine Generator Units. free for other purposes; and the concentration of power under one management results in the installation of more efficient machinery, and a marked reduction in the num- ber of high priced attendants. The Bessemer Building, a new office structure, now being supplied with light, heat and power from this center, is the forerunner of others which are soon to follow. Building. The building in which the power generating ma- chinery is housed is ten stories high, of heavy steel frame with brick curtain walls and Indiana limestone trim- mings. It rests upon a massive concrete foundation, which is carried down to a bed of gravel. Space is left on the four sides to give light and air, and there are large windows on all sides, which are protected by roll- ing steel shutters. The machinery and boiler floors are of concrete, between the steel beams and over them, while * Abstract of a paper read before the Engineers’ Society of Western Pennsylvania, September, 1904, by Gerald B. Flanagan. forms being available. There are two passenger eleva- tors, each of a capacity of 3000 pounds live load, and one large freight elevator of 10,000 pounds live load capac- ity. The stairway is entirely of iron and steel. The first, or engine room, floor is nearly 6 feet above the sidewalk, safely above the highest recorded flood stage, making it about 33 feet 6 inches above pool stage of the Allegheny River. Even at the highest level no water can flow into the basement, and as an additional safeguard. the gen- erator foundations are so constructed that if the base- ment was filled with water none could reach these ma- chines. The basement floor is 20 feet 6 inches below the engine room floor, and is formed of 4 feet of concrete over the entire surface placed directly upon the gravel. From this base rise the outer walls carrying the exterior col- umns, and in the center a mass of concrete, forming foun- dations for the large engines and heavy interior columns supporting the coal bin and the boiler and manufacturing floors.

The center space is thus left open to the bottom of the coal bin, which occupies the center of the fourth and fifth floors. Arrangement of Wachinery. The arrangement of the machinery will be understood by reference to the illustrations. On the first floor, in the center, are the two large engines direct connected to al- ternating current generators, with room for a third unit. To the left of these are two elevator pressure pumps, also with a place for a third. On the right are located two small engines direct connected to direct current gen- erators which excite the large alternators. In this room is also located the switchboard. At the rear of this room are the vertical steam pumps, which draw the general water supply from the river, the base of these pumps being 6 feet 6 inches below [IRON AGE. 3 bearings are water cooled. The fly wheels are 19 feet in diameter, and weigh about 200,000 pounds each. These engines are direct connected to 1000-kw. three-phase, ro- tary field, Westinghouse generators. They are 80-pole machines, running at 90 revolutions, giving 7200 alterna- tions per minute. Over the engines and generators is a 25-ton electric traveling crane, built by Pawling & Har- nishfeger of Milwaukee, Wis., and there is a sunken way in the engine room floor which permits the entry of wagons at the street level to a point commanded by the crane, thus facilitating the delivery or removal of ma- chinery, &c. When not in use this space is covered by a movable floor. Two 12 x 12 inch Harrisburg engines are direct connected to 60-kw. Westinghouse direct cur- rent generators. These are used for exciting the fields of the large alternators, and for other purposes for which direct current may be required. The switchboard, 7 feet View of One Side of the Lower Tier of Babcock & Wilcox Boilers and Stokers on the Second Floor. the basement floor; and beneath this level is a small sump into which all leakage in the basement collects and is pumped into the river. The remainder of the basement is occupied by the two boiler feed pumps, with room for a third; feed water heater, with space for a second one; softening apparatus for feed water, exhaust muffler and grease separator, return water tank and small receivers and pumps for various drains. In the basement on the other side of the building are located the accumulators, a large air tank for cushioning the return line to the ele- vator pumps, and a pump at the artesian well which sup- plies the drinking water. In a small intermediate base- ment in front of the engine foundations are located the filters for the boiler feed purifying system. On the second floor of the building are located the boilers, and the third floor is arranged so as to be finally used for the same purpose, thus doubling the present capacity. Above the level of the third floor boilers is the coal bin. Description of Machinery. The engines are of Westinghouse-Corliss vertical cross compound type with reheating receiver ; the cylinders are 28 and 46 x 48 inches. Both the guides and the main 6 inches high and 30 feet 4 inches long, has one panel for direct current, three for the alternating generators and six distributing panels. It is of blue Vermont marble mounted upon an iron frame, and is equipped with im- proved forms of all instruments necessary for the control of large currents. The lead covered cables from the gen- erators to the switchboard are taken in conduits under the floor. For elevator service there are two Laidlaw-Dunn-Gor- don special elevator pumping engines of the three-cylinder compound horizontal pattern, 21%-inch high pressure cylinder and two 28-inch low pressure cylinders, with reheating receivers ; the plungers being 644 inches in diam- eter and the stroke 24 inches long. These machines de- liver water against a pressure of 850 pounds, the capacity being 700 gaHons per minute. The elevators, both freight and passenger, were built by the Otis Elevator Company, and are high pressure machines, operating with S850 pounds hydraulic pressure. They are supplied witb all up to date devices for operating and for safety. The accumulators were also supplied by the Otis Company. They have plungers 12 inches in diameter by 12 feet stroke, and are weighted with cast iron rings, one being aocnennencinpaiergiamesit ce: e bi ’= 2 4 THE IRON AGE. weighted slightly in excess of its mate, which is con- nected to a chronometer valve on the pressure pump by means of wire rope, so that the motion of the accumulator plunger starts and stops the pump. The second accumu- lator, being more lightly loaded, will be the first to rise and the last to fall. They are arranged so that if one of them be put out of commission the other may be quickly connected to either of the pumps. These machines have automatic stop valves which throttle the water, and so bring the moving mass of iron quietly to rest at each end of its travel. Water for all purposes except drinking, including fire service, is supplied by two vertical tandem compound duplex Wilson-Snyder pumps with cylinders 18 and 30 September 15, 1904 In addition to the apparatus above mentioned there are a number of small pumps, one for discharging the water from the basement sump; another for taking the water from an open tank in which the returns from various lines are. collected; a receiver and pump which takes all drips from steam separators and high pressure lines; and a small receiver and pump which takes the greasy drips from the feed water heater and the grease separator. There is also an air compressor for supplying air to the cushions on the hydraulic system ; and oil filters and pumps for the lubricating system. Coal is delivered at the two large receiving doors on Cecil alley, and falls through heavy cast iron gratings into hoppers beneath. From there it is raised by two ele- [ff LULL se i I as i | | atthe AS eh Lo | < if — q i} | HO) |, i My Joe o Lael | RS ue oF 6220) OZ2ZO B | en fe) ee Fee OFFO) |OFFO)!| [7 Ybor ia pay =F | @ es a. fe a "Y a7 Lela) bl aad | oc 0 - - y "7 | a Y f, Bane m4. pede |g | cals Ne ee > “TY on: eter pS ar PU ELEVATOR RETURN 14’ PIPE — $—__, 11 Scal ! | P FE “i a7) LD) B | i] Oo ——— : 5 r BS A, | ; = “.

The boiler feed is furnished by two Wilson-Snyder compond duplex pumps with 8 and 14 inch steam cyl- inders and 7-inch water cylinders by 18-inch stroke. The Scaife system of treating tanks and filters is used for purifying the water before it enters the boilers. This Apparatus consists of two solution tanks provided with small pumps for forcing the solutions into the two pre- cipitating tanks. The latter are closed, being required to withstand a pressure of 200 pounds. Thfough these tanks the water travels very slowly, while the bulk of the impurities settles to the bottom. From here the water goes to the filters, of which there are four, also of the closed tank pattern. The feed water heater is of the closed rectangular pattern, made by the Pittsburgh Heat- er Company. ‘ vators, designed by Heyl & Patterson, Pittsburgh, Pa., to belt conveyors which traverse the entire length of the coal bin. Moving trippers travel the full length of the conveyors and distribute the coal evenly along on both sides. The coal bin is of heavy steel plate stiffened with I-beams, and is lined with cement plaster upon wire net- ting, the bottom being built into hopper forms for each pipe opening. Pipes, 12 inches in diameter, lead directly to the stokers at the boilers. The present installation includes 12 Babcock & Wil- cox water tube boilers, aggregating 3600 horse-power. Each boiler contains 140 4inch by 18-foot water tubes and two 36-inch by 18-foot drums. They are built two in a battery, and are furnished with Babcock & Wilcox chain grate stokers, this construction giving free access to one side of each stoker. The furnace gases discharge di- rectly in the rear of the boilers; those from each boiler into a separate vertical flue provided with q damper September 15, 1904 which swings open of its own weight, and is held in the desired position to check the flow of gases by a chain. The vertical flues are 15 inches by 10 feet, and rise di- rectly to a 4-foot by 10-foot horizontal flue. They have expansion joints about the center of their length. The horizontal flues each have two expansion joints, and are suspended from the girders above in such a manner as to admit of the requisite motion in the direction of their length. They are provided with numerous cleaning doors. There are two stacks, one for the boilers on each side of the building. The stacks rest upon heavy girders, and are connected with the horizontal flues by short sections containing expansion joints. Each stack is 11 feet in diameter inside, and rises to.a hight of 200 feet above the grate bars. It is built of %-inch steel plates, except the bottom ring and the rings where it is stayed to the build- THE IRON AGE. . the screens is a grating made of round wrought iron bars 2\, inches in diameter; these are dropped into sockets in massive cast iron beams and may be removed singly. At the supply pumps the system of valves is such that each of the pumps may draw from either, or both, of the intake pipes, and also that the pumps may discharge into either of the intake pipes while drawing water through the other one, for the purpose of blowing out any sedi- ment which may collect in them. From the discharge side of the pumps a 16-inch main leads to the various prop- erties, a 6-inch branch being taken off to supply the gen- eral needs of the power building, while a 10-inch line leads to the boiler feed pumps. From the feed pumps an 8-inch line leads to the feed water heater, and from there a 6-inch line takes the hot water to the purifying system, and then reaches the boilers through various smaller f — i be & i , 10 PIPE ; “ z | & - + z e ° = es C-ENGINE} a8 ~~ -$ +} s \ i yh | y t || a 10 Pipe | "%y | ‘ 2 2 3s oy | w z = ae : : a # = oo gH - ee vey 7 | = x - f 3 2 | gt ae a $ i « 7) t t . x = } 6 5 st : 2 é | oO €-ENGINE 2 a o i Eh ies =—_ | S f FS Ww > | | j ‘ = KM Wa torr + Pe pe — cece el —- | oY 4) YW —-+- PWE mn noe lente a — DIRECT SEPARATOR % r} ae — = not | | | al | : E et } a y — - — -——__— Sf - - ++ —e en a — 5 r it 8 Rierennas F| | . i te oe 4 - rt i | x ) = | J¥; | “+ — eo Yoo. ne | 4 - -SENGING- 3 - —— —- } a >. eer —75) 0 < — are : ' \ = | 4 | UW oie £ | } ad \ ntanlion + 7 - prem fntinss 3, k -} - 4 sot Tt + >< abe " } At ong - hea hed atl = tn 2 oF _} . => nay es i ie —opa | (0-H ; ] | ‘yl i->, ae ’ ‘ eur — um + apie. } Te Se * ‘ = eee Tl 7 | G Ved = i a | + : , - ' a 4 r | | ! | be 645 +e — 40-6" - — pe - - 4000” — - he -0h C- ae a | s le , | a ip come - j ~ + 64 oe — + ——s-s0)o" + — _ e+ +- Nuceasaep <xsp'letnapnehinglt Will seeiiilltaaii? stan ininae } i ~~ oe | } on roe we a eS ae T BH ae. hl aes at: se % r THE IRON AGE) 4 a ' - -_— — — —- — aeje- - aan i i w+ -—-————--- se- —--- > Plan of the Boiler Room Floors and the Live Steam Mains. ing at the roof, which are % inch. There are four sub- stantial brackets at the base which rest upon the steel work of the building, and the top is stiffened by a ring made of two 6 x 6 x % inch angles, and below this a Z- bar ring for carrying slings for painting. A ladder ex- tends from the roof to the top of the stack. The stacks are not lined. Around the 11-foot stacks are tile wall in- closures 13 feet square, permitting the intervening spaces to serve as ventilating shafts for the engine and boiler floors. The Piping System. The piping system is never the least important part of a power plant, and in this instance it really constitutes itself a leading feature. Water Supply and Boiler Feed.—On the bank of the Allegheny River is a massive concrete block which forms the intake for the water supply, and from this point two 16-inch cast iron bell and spigot pipes lead to the supply pumps in the power building. The screens are formed of angle bar frames with bronze wire netting, and are dropped into slots formed in the concrete. In front of branches. Valves are arranged so as to by-pass the heat- er, treating tanks and any one or all of the filters, so that the plant is operative with these devices entirely out of commission. The feed water mains are of wrought iron, and the smaller branches at the boilers are of brass. Near the feed water heater is a nickel seated water re- lief valve set at 220 pounds. Steam Pipes.—Steam from the boilers is collected in 14-inch headers on either side of the building, and these are connected at one end. From both headers 10-inch lines lead to the separators at each of the large engines, so that each engine may draw steam from any or all of the boilers. Erhaust Steam Pipes.—Exhaust steam leaves these engines through 18-inch pipes, which are collected into a 24-inch line and finally into a 30-inch main and riser, which terminates in a Jarge exhaust head above the roof. Since exhaust steam is to be used for heating a 30-inch back pressure valve is located in the horizontal main; and behind this valve are collected branch lines from all the steam using machinery, but arranged in such qa way 6 THE IRON AGE.

View Showing Switchboard, an Exciter Set and the Wilson-Snyder Vertical Duplex Pumps for the General Water Supply. haust from these engines may also be forced into the Boiler Blow Offs.—From the boilers on each side of steam heating mains. the building the blow offs collect into short 4-inch mains, Waste Steam.—The steam wasted through the safety and these, in turn, join and form two 5-inch lines which valves is collected into two 8-inch mains, which, in turn, discharge into a private sewer. Perearat penalise ode September 15, 1904 THE Hydraulic Lines.—The elevator pressure pumps dis- charge into 8-inch pipes, and these lead into a 10-inch main from which branches are taken to the pressure side of the machines. A 6-inch branch is also taken to the accumulators, and on this branch is located a large air chamber fitted with a valve to prevent the air from es- caping should the pressure in the line fall. The return water from the elevator cylinders comes back to the power building through a 14-inch bell and spigot pipe and goes directly to the suction side of the pumps, the por- tion of the line within the building being of galvanized steel pipe. There is a large air tank on this line to cushion the shock of the moving body of water. A 6-inch branch leads to a wooden tank above the roof of the pow- er building, which acts as a reservoir. Its altitude is sufficient to maintain a pressure of about 75 pounds against which the machines must discharge, the object being to guard against the possibility of the cylinders emptying themselves, as they are placed vertically and contain a column of water of greater hight than the atmosphere would support. ‘The large operating valves of the elevators are moved by cylinders operated by small pilot valves, and these small valves take water from the 75-pound line and discharge it at atmospheric pressure. This water returns to the open tank and is saved, as it has been previously treated and filtered. Return Water Lines.—A small amount of live steam is used in the office buildings for heating water, and the condensation from this is returned to the open tank, as is also that of the exhaust steam from the heating system and the discharge from the elevator pilot valves. The water from this tank is pumped through a 4-inch pipe to the tank above the roof, replacing the loss in the hy- draulic system.: When the roof tank is full a float op- erated stop valve closes, and the pressure rises sufficient- ly to open a check valve in a branch line leading to the feed water system, entering it behind the heating and purifying apparatus. The clean drips from steam sep- arators, &c., are pumped directly into the feed pump dis- charge, and the oily drips from the grease separator and condensation in the feed water heater are pumped into the elevator pump suction line. Piping Details.—All valves and pipe fittings of a given size in this building are interchangeable, from the small- est size up to 14 inches, this being the largest size used for any purpose other than exhaust steam, with the ex- ception of the high pressure hydraulic lines and a few fittings directly connected to the main supply pumps. Aside from the hydraulic lines, all valves and fittings are plain faced, the flanges above 6 inches being rolled steel, the fittings cast iron. All flanges and fittings have ma- chined surfaces for bolt heads and nuts, and the under sides of bolt heads and nuts are faced. The bolts are made from refined wrought iron. All bolt holes are drilled, the number of holes being four in the small sizes and some multiple of four for the larger ones. The cast iron flanges are threaded in the usual way, and the rolled steel ones have grooves into which the pipe is peened. The pipe hangers are entirely of forged steel, and are provided with turn buckles for adjusting the length. The flanges and fittings on the hydraulic lines are of a type especially designed for this plant. The flanges are screwed to the pipe, and are then turned in the lathe so as to leave the pipe and a portion of the flange immediately surrounding it projecting a considerable distance from the face. This projecting portion is slightly curved on its face, the highest part occurring on the pipe itself, and between these pipe ends the heavy copper gasket is com- pressed. It will be seen that there are no male and female joints in this system; all flanges of a given size are alike, a corresponding projection being formed upon the fitting. Alli the fittings are steel castings, the flanges being of forged steel. The elbows are of long sweep pat- tern, and the tees are strengthened with heavy ribs. In order that the gasket may center itself readily, its outside diameter is made equal to the inside diameter of the bolt circle. A few of the bolts are put in place and the gasket slipped in between the flanges; the remainder of the bolts are then inserted and the joint tightened. The power building being supplied with coal returns power in various forms, such as electric current, alternat- IRON AGE. 7 ing and direct; steam at 150 pounds, or any lower pres- sure; water at 150 pounds, or ac o50, and compressed air. At present these lines are taken through an underground conduit to the Bessemer Building. In the future, the ground through which this conduit runs will be covered with tall buildings, and the pipes will then appear in the basement of one or more of them, being already provided with branches from which lines may be taken to supply the buildings through which they pass. The engineering and architectural designing of the Phipps Power Building, as well as the superintendence of construction throughout, was in charge of Julian Ken- nedy, engineer, Pittsburgh, Pa. ~ e < Philadelphia Foundrymen’s Association. The regular one hundred and thirty-seventh meeting of the Philadelphia Foundrymen’s Association was held at the Manufacturers’ Club, in that city, Wednesday evening, September 7. It was the first held since the summer vacation and was quite largely attended. In the absence of the presiding officers, Dr. Elmer E. Brown called the meeting to order, J. S. Hibbs acting as secre- tary pro tem. The various standing committees not hav- ing been in session during the summer, had no report to make. The treasurer reported a balance in the treas- ury of $1836.59, with all indebtedness paid. After routine business had been transacted Charles H. Thomas, presi- dent, and F. C. Everett, secretary, of the Associated Foun- dry Foremen, a branch of the American Foundrymen’s Association, were introduced, and explained to those present the aims, endeavors and benefits of the member- - ship to foundry foremen in the organization. It was proposed to organize a local branch, and to aid in this movement a motion was passed directing the chair to ap- point a committee of three to aid in this work. The fol- lowing committee was appointed: G. Williams, Adam Pugh and G. M. Beckert. A later motion instructed the secretary of the association to make the call for the first meeting, and that the various foundrymen be particularly requested to have their foremen attend this meeting. The paper before the association at this meeting was entitled “ Mechanically Made Cores,” by Geo. H. Wads- worth, Cuyahoga Falls, Ohio. After the reading of the paper a practical demonstration of the 6-inch core ma- chine, electrically driven, was made, and the method of operation, shape, condition, &c., of the core were shown. as was also all the various parts of the machine for mak- ing cores of all sizes, round, square or of prismatic shapes. ee Pittsburgh Reduction Company.—The Pittsburgh Re duction Company of Pittsburgh, with works at Niagara Falls, N. Y., and New Kensington, Pa., and manufacturer of pure aluminum, intends to install mills at the New Ken- sington works for the rolling of aluminum sheets. A contract has been placed with the A. Garrison Foundry Company of Pittsburgh for the building of three 28-inch plate mills. pennants The average cost of moving freight in various coun- tries has recently been stated to be: Great Britain, $2.30 per 100 ton-miles; Austria, $2.05; France, $2; Germany, $1.88; Russia, $1.75; the United States, 72 cents. These figures place the American railroads so far in advance of their European counterparts that “ there is no second.” The London & Northwestern is one of the best operated of the English roads, and here the cost is placed at $1.49, the average trainload being 72 tons. With an average trainload of 387 tons, the New York Central exhibits a cost of 41.5 cents, while the Pennsylvania, with 518 tons, operates at a cost of 40 cents. ——— ——- ~>-——— The High Speed Steel Test.—The high speed steel test which was to have taken place September 10 at the World’s Fair has been postponed for a short time, owing to the fact that some of the foreign manufacturers could not get their steel to America in time. Assurances are given, however, that the test will be made at an early date. 8 THE The New Two-Foot Arm National Radial Drill. A new radial drill has been brought out by the Fosdick Machine Tool Company, Cincinnati, Ohio. The accom- panying half-tone shows it equipped with a tapping at- tachment. These machines have been designed to cover a field of work between that requiring a large radial drill and that requiring an ordinary upright drill. The aim was to combine in one machine the advantages of both types. The back gears and tapping attachment are located on the head, the latter being operated by a lever within convenient reach of the operator, which may also be used for starting and stopping or reversing the ma- chine. The arm swings on ball bearings and is raised or lowered by power. The head is moved along the arm by screw and nut and is provided with a clamping device. The machines are provided with eight changes of speed THE FOSDICK NEW TWO-FOOT and three changes of feed in geometrical progression and are furnished with or without tapping attachments, as desired. The machine will drill to the center of a 48-inch cir- cle. It is capable of drilling a 24-inch hole through solid cast iron, a 2-inch hole through solid steel and will force a 2-inch tap through cast iron. The spindle is bored to fit a No. 4 Morse taper and has a traverse of 12 inches. The minimum distance between the column and spindle is 10% inches and the maximum distance between the spindle and base plate is 48% inches. The traverse on the saddle of the column is 30 inches and the traverse on the head of the arm is 14% inches. The total hight of the machine is 90 inches, and with the spindle in its highest position 97% inches. The driving pulleys are in- tended to run at a speed of 250 revolutions per minute. The floor space occupied is 6 feet 6 inches by 6 feet 8 inches, and the total weight 2400 pounds. ———>--e—__—_ One of the two large traveling cranes at the Govern- ment coaling station at East Lamoine, Maine, was blown down in a recent gale.

Within the last few years there has been a growing tendency on the part of manufacturing companies to en- list the efforts of their employees in bringing out new ideas as to better methods of manufacture, new uses for products made and any other suggestions that would be beneficial to the employees. Recently the Nernst Lamp Company of Pittsburgh made practical use of a number of suggestions submitted by employees, for which re- muneration was made. The American Sheet & Tin Plate RADIAL DRILL. Company has actively taken up this matter of securing co-operation of employees for mutual advantage, and re- cently posted notices at the Laughlin tin plate works, at Martin’s Ferry, and the Aetna-Standard sheet mills, also at Martin’s Ferry, Ohio, as follows: “For the purpose of stimulating the use of our vari- ous products of both the sheet and tin mills by develop- ing new purposes to which they may be advantageously put, we desire the co-operation and assistance of yourself and all subordinates, including the workmen in your mills. We feel that with the assistance of this vast amount of intelligence we may reasonably expect results that will largely increase our tonnage. “ We would like to have it understood that any one of- fering suggestions which are developed so as to increase the consumption of our products will be properly com- pensated after such development shall have taken place. It will also be an opportune time to have our workmen understand that we stand by willing and ready to prop- erly compensate them for any method or device they may suggest or design that will reduce our cost of manu- facture.” September 15, 1904 THE The Dake [lotor for Foundry Service. The Dake square piston engine, built by the Holland Company of Chicago, I1l., is a compact motor, which may be operated by compressed air or steam. It is built in sizes of from 1 to 20 horse-power in a form that is pe- culiarly adapted to the direct driving of blowers, pumps, hoists and machinery of almost any class, and for this reason is useful for many purposes in foundries. The accompanying illustration shows the motor applied to a drum friction hoist, a shape in which it may be used for raising a large weight for casting smashing and for raising charging lifts or other hoisting machinery. It runs equally well upside down or in a vertical position. Other special services to which the motor may be put in the foundry are the operation of jib or traveling cranes for the handling of flasks and castings, or the raising, lowering and pouring of ladles. It is easily capable of running a crane that requires several men to operate it by hand power and will raise the load in about one-fifth of the time. One of these motors may be applied to any ordinary hand crane simply by removing the cranks and Being com- without changing the gearing in any way. IRON AGE. 9 lished in 1854 by R. D. Cole, a carpenter and cabinet maker, who with his brother, Matthew Cole, is still at the head of the business. a Electric Cranes in a Basic Bessemer Plant. In a new basic Bessemer works recently erected by the Chatillon-Commentry Company at Neuves Maisons, France, the entire manipulation of the ladle, both for charging and casting, is effected by overhead traversing cranes worked by electric motors. The shop is planned to contain four 18-ton converters and two gas heated mixers, each of 220 tons capacity, but only three of the former and one of the latter are at present in use. They are all placed with their axes in one line, about 70 m. long, with the mixer at one end. The crane which runs parallel to this line, upon overhead rails, carried upon pillars about 40 feet high, has a span of 15 m., with a maximum lifting power of 35 tons, which can be lifted 6 m., moved sideways 10 m., and longitudinally through the entire length of the shop; the working speeds under the maximum load being 3, 20 and 80 m. for the different movements, respectively. The ladle is suspended by trun- nions resting in open hooks at the ends of a pair of A DAKE SQUARE PISTON ENGINE DIRECT CONNECTED TO A FRICTION DRUM HOIST. pletely inclosed in an air tight case, it is well protected from the fine dust and dirt that invariably prevails in foundries. In the outfit illustrated a friction lever and foot brake are provided. The lever is shown in the posi- tion for lowering the load. In the opposite position, 45 degrees over, it starts the drum for hoisting and in the central, or neutral, position the drum is fixed and the load held stationary. A similar equipment is made with a tight drum instead of a friction drum and a reversible engine is used, so that power is used for both hoisting and lowering. e ——_o+@e —- The coal consumption of the Moulineaux power sta- tion in Paris has been made the subject of recent tests, the result of which shows a total consumption for all pur- poses, including all auxiliary apparatus, of 2.2 pounds per kilowatt hour. There are nine units, each of a capacity of 800 kilowatts, of which six are operated by triple expansion four cylinder engines, and the remaining three by cross-compound engines. The boiler plant contains nine batteries of Meunier boilers, each battery comprising three units. The R. D. Cole Mfg. Company, Newnan, Ga., is cele- brating its semicentennial this year. The company makes engines, boilers and structural steel work. and has the largest plant of the kind in the South. It was estab- screwed rods, which can be raised or lowered by a re- versible motor with worm wheel gearing on the travers- ing platform. The tipping is done by two similar rods, which bear against stops on the outside of the ladle. The metal from the blast furnace, brought by a steam locomotive upon an elevated railway, about half the hight of the shop, is lifted by the crane to the receiving mouth of the mixer and poured in; the same ladle also takes the charge for the converters. The finished steel is taken by another ladle to the ingot molds, which are mounted on cars on a transverse line at the opposite end of the building, the same crane being used. This, how- ever, is only a temporary arrangement, as a second crane, in course of erection, is to be provided for handling the finished steel, the first being reserved entirely for the mixer and charging the converters. The crane driv- ing station is upon a platform suspended from one of the main girders which carries the starting and revers- ing gear for the four different movements, as well as the switch board. Direct current at 500 volts is used with series motors capable of bearing a considerable overload ; the transmission is partly by leathered gearing with raw hide pinions, and partly by leather belts with elastic couplings, in order to insulate the electric from the other working parts. The girder work of the crane has been built by Bietrix, Laflawe & Co. of St. Etienne, and the electrical parts by the Westinghouse Company. Ca . erent nore soe. Te ae — ones z ~ - — 10 THE IRON AGE. The American Bridge Company’s Am- bridge Works. The Eye Bar Shop. In The Iron Age for August 4 we published a descrip- tion of the great bridge plant of the American Bridge Company at Ambridge, Pa., particular attention being given to the design and equipment of the main bridge shop. We now take pleasure in laying before our read- ers a description of the eye bar shop, in which hydraulic machinery is employed in the production of eye bars up to any size required. The Bullding. The eye bar shop is a steel building 220 x 225 feet, with concrete curtain walls; and has a floor space of about 50,000 square feet. It is especially designed for the handling of the long bars necessary in eye bar work, and is divided into three bays, the middle bay and two side bays. The middle bay is 60 feet wide and is served by a 20-ton electric traveling crane, with 35 feet head room under it. Each of the side bays is 80 feet wide and September 15, 1904 necessary roller tables and skids, but otherwise left clear for the passage of eye bars from one operation to the next. Electricity for the motors and water at a pressure of 800 pounds per square inch are supplied from the power house nearby. Heating and U psetting. The stock is run into the shop on a narrow gauge track, from which it is taken and charged into the fur- nace by a specially designed charging crane, which runs along the side bay in front of the furnaces and the machines. It consists essentially of an electric traveling crane of 27%-foot span. It is fitted with a lifting beam which is a box girder 41 feet long. This lifting beam forms a runway for three four-wheel trolleys, which carry electro magnets of 2500 pounds lifting power each. The traverse of these trolleys is accomplished by an independ- ent motor connected with the trolleys by an endless rope. Telescopic guides, strongly braced to the bridge, serve to prevent any swaying of the lifting beam due to the traversing of the trolleys. This crane carries stock to and from the furnaces, inserting the ends or withdrawing them by simply traversing the trolleys. Vig. 1—The 30 x 44 Inch Upsetter in Bye Bar Shop. THE AMERICAN BRIDGR COMPANY’S AMBRIDGE WORKS. 20° feet 6 inches in the clear between the floor and the bottom part of the roof trusses. Each of the side bays is served by parallel sets of electric traveling cranes, with 27\%-foot span. The building itself is a steel frame with heavy roof trusses, firmly braced to carry the numerous overhead cranes, and is supported by columns in the side walls and by two columns which are centrally located, one on each side of the middle bay. The walls are of concrete, laid in panels 8 feet high, with numerous sliding doors on all sides. Apove the concrete is a continuous belt of slid- ing windows 10 feet high. The roof of the middle bay is raised 8 feet above the roofs over the side bays, this space being inclosed with sliding windows. Dormers in the roofs over the side bays and skylights in the roof over the middle bay shed additional light. The balance of the siding is corrugated steel. Half of the building is equipped with especially de- signed uydraulic machines for forging heavy eye bars (i. e., those above 8 inches wide), while the other half is reserved for a set of lighter machinery, with which eye bars up to 8 inches wide may be forged and handled more speedily. The furnaces and machines are placed in a row along the middle bay in the order in which they are used, so that tne process is a progressive one from start to unish. The side bay in use is equipped with the , After heating, the bars are delivered by the charging crane to the hydraulic upsetter, Fig. 1. The process performed by this machine is the upsetting and forming of the heads, which is accomplished by dies, moved by hydraulic rams. There are three rams, as follows: The upsetting ram, the die closing ram and the hydraulic grip. These rams may be operated at pressures varying from 800 to 7000 pounds per square inch. The higher pressures are obtained by means of intensifiers. The rams are controlled by hand pilot valves, conveniently arranged for the operator. The upsetting cylinder is horizontal, while the die closing and grip cylinders are vertical, being carried by massive housings. The func- tions of the rams may be inferred from their names; the upsetter moves the dies, thereby forming the head; the die closer prevents the dies and bar from buckling, and the grip prevents the bar from backing out of the ma- chine. The dies are readily changed to accommodate the machine to the varying sizes of eye bars. As men- tioned before, this machine is served by power driven roller tables, with reversible rolls, which reduces the handling of the bars to a minimum. Punching. After upsetting, the bars are taken by an electric crane to a hydraulic punch, Fig. 2, which punches the September 15, 1904 THE pin hole to a less diameter than the finished hole. This punch is cnerat.d under a pressure of 6000 pounds per square inch. Four vertical bolts take all the punching strain. | } iat aed ee eee Fee EK -_ aniiiiaaemes a a Been a Fig. 2.— IRON AGE. 11 mounted one above the other, the upper one being ad- justed by heavy screws, which are operated by an in- aependent motor.

The shear is quite similar to the punch and E Sect BER barren bee ae hast a ee Seen inant gn li hag ESR a Deon ee eae) “s See a 12 THE IRON AGE. consists of a top and bottom steel casting, the castings being held together by four tension bolts. The top cast- ing carries the hydraulic cylinder and ram which operate the knife. After shearing, the bars are turned end for end and heads are formed on the other end in the same manner, as just described. With heads forged on each end, the bars are ready to be straightened.
