INTRODUCTION 
 
 THE Works of the South wark Foundry and Machine 
 Company were founded in 1836, and occupy the entire 
 block bounded by Washington Avenue, Federal Street, 
 Fourth and Fifth Streets, covering about five acres of ground, 
 in the southern section of Philadelphia, known in the early 
 history of the city as the District of " South wark," from 
 which our name is derived. 
 
 The Works consist of Machine and Erecting Shops, 
 Boiler Shop, Smith Shop, Iron and Brass Foundries, Pattern 
 Shop and Pattern Store Houses. 
 
 The Machine Shops have an aggregate floor space of 
 65,500 square feet, and contain a complete equipment of 
 modern tools and special appliances for finishing the largest 
 castings and forgiugs used in engineering construction. 
 
 The Main Erecting Shop, which is 76 feet wide by 
 
 3 
 
Introduction 
 
 253 feet long, is equipped with two electric traveling cranes, 
 each capable of handling fifty tons. 
 
 The Iron Foundries cover an area of 40,250 square feet, 
 and are equipped with three traveling cranes of fifteen, thirty 
 and fifty tons capacity respectively. Our facilities for making 
 castings of all kinds are unexcelled. Modern melting fur- 
 naces, core ovens and core sheds, together with the crane 
 facilities before mentioned, and improved methods of hand- 
 ling the raw materials, enable us to produce iron castings at 
 the cheapest possible cost and of the largest sizes practicable. 
 
 In our Brass Foundry we have facilities for the produc- 
 tion of bronze and composition Castings of any description. 
 
 The Boiler Shop, 107 feet wide by 190 feet long, is 
 fitted out with hydraulic riveting machinery and all modern 
 appliances for building boilers of large size. We make a spe- 
 cialty of Horizontal Tubular Boilers, Marine Boilers for high 
 pressures, Tanks, Stacks, and Miscellaneous sheet iron work. 
 
 The Pattern and Smith Shops are fitted with modern 
 appliances for rapidly turning out work in their line. 
 
 Hence it will be seen that we control practically all

Introduction 
 
 branches of the business pertaining to the manufacture of 
 the various classes of machinery we build. 
 
 The tracks of the Pennsylvania Railroad Company are 
 located on Washington Avenue, and three sidings enter the 
 Works, which enables us to receive all supplies by carload and 
 ship our products in the same manner. This railroad con- 
 nects with all the Trunk lines of the country, facilitating 
 transportation to any point at lowest rates. 
 
PORTER-ALLEN ENGINES 
 
 ONE of our leading specialties is the manufacture of the 
 Porter-Allen Automatic Engine, in sizes of 45 H. P. 
 and upwards. The smaller engines up to 150 H. P. 
 are built exclusively of the simple high pressure type ; above 
 150 H. P. we build them both Simple, Compound and Triple 
 Expansion, to meet the requirements of the purchaser. 
 
 We publish a treatise of this engine which gives an 
 exhaustive description of the design and construction, and 
 are pleased at all times to furnish interested parties with a 
 copy of the same. 
 
 In general, the advantages of this engine are its high 
 economy in the use of steam ; close regulation under widely 
 
 6 
 
Porter- Allen Engines 
 
 fluctuating loads ; convenience and economy of installation 
 and adaptability of service. 
 
 In connection with the foregoing notice of special ad- 
 vantages, and which we might largely extend, we will but 
 briefly invite attention to the general character of the work 
 put upon these engines. 
 
 This is intended to be such as to render them free from 
 the ordinary troubles which are met with in the care of 
 steam engines, and to give them a durability that shall leave 
 nothing to be desired. To accomplish this, no pains have 
 been or will be spared. 
 
 In addition to a self-contained and substantial construc- 
 tion, which maintains truth of alignment and prevents all 
 yielding or vibration, or distortion of either large or small 
 parts, and to the severe mechanical correctness of all move- 
 ments, and the employment of the very best materials, we 
 attain in all the working parts, practically, entire truth of 
 form, true plane, and true cylindrical surfaces, and we make 
 these, wherever it is desirable, of an indestructible character ; 
 everywhere when wear or thrust has to be resisted, we provide 
 large and well-fitted surfaces. 
 
Porter-Allen Engines 
 
 All excellences of mechanical construction will be found 
 in these engines. 
 
 We do not compete with engines in which anything 
 whatever is sacrificed to cheapness of construction. Our con- 
 fidence that the class of work done by us is worth doing well 
 and will be appreciated, has been amply verified, and we pro- 
 pose to maintain a uniformity of excellence which we have 
 been at the utmost pains and large expense to insure. 
 
 The valve gear is designed to give the best possible dis- 
 tribution of steam, and the valves are small ; have short 
 movements, and are operated without loss of efficiency. They 
 are four in number, one for admission and one for release at 
 each end of the cylinder. 
 
 These valves stand in the vertical position, the admission 
 on one side of the cylinder, and the exhaust on the other ; the 
 latter are so placed as to completely drain the cylinder. 
 
 These valves are perfectly balanced, and produce practi- 
 cally no wear on the seats. Each valve opens simultaneously 
 four passages, two on each face for the admission or release of 
 the steam. 
 

Porter- Allen Engines 
 
 Their draft is central, which causes both the valves and 
 their seats to maintain truly plane surfaces. 
 
 The exhaust valves are in contact with only a small 
 portion of the cylinder; the exhaust, therefore, abstracts 
 externally but little heat from the cylinder, and none from 
 the entering steam. 
 
 The governor is of the well-known Porter type, and 
 stands unexcelled as adapted to stationary engines requiring 
 close regulation. The active parts are very light, the power 
 being derived from a high rotative speed, causing a sensitive- 
 ness in its movements that will arrest fluctuations and 
 produce uniformity in the running of the engine. 
 
 The speed of this governor being constant makes it equally 
 efficient upon an engine running at either a high or low num- 
 ber of revolutions. We manufacture and sell these governors 
 separate from our engines. 
 
 The main bed-plate is a single heavy casting, and forms 
 the main stay and backbone of the engine. It has a very 
 broad base, resting with large surface contact on the 
 masonry, continuously from one end to the other. 
 
Porter- Allen Engines 
 
 It carries trie cross-head guides, and all the brackets 
 forming part of and carrying the main valve-gear, including 
 the governor, thus rigidly securing all the vital parts into 
 one main body. 
 
 At one end of this bed-plate is provided a circular hood 
 of substantial character, to which the cylinder is attached; 
 the other end of this casting contains the main bearing which 
 is fitted with heavy quarter boxes and binding cap, the whole 
 being lined with our best Babbitt's metal, hammered in place, 
 bored and scraped to a perfect fit on the shaft. 
 
 The adjustment of the quarter boxes in the main bearing 
 is made from the top by means of bolts holding wedge slabs 
 of equal length to the journal, thereby insuring a most 
 substantial support to the shaft. 
 
 The crosshead has large bearing surfaces and is fitted 
 with a forged steel pin placed in the middle of its length. 
 Being incapable of deflection, it is equally in contact with the 
 guides at every point. 
 
 The connecting rod has a solid crank end and strapped 
 crosshead end, both ends having boxes, lined with our best 
 
 10 
 
s o 
 

 xl 
 
Porter- Allen Engines 
 
 Babbitt's metal, soldered or fused in place, bored in their 
 respective journals, and adjustable to maintain a constant 
 length of the rod. 
 
 The crank is of disc form, cast in a single piece, with 
 turned and polished rim, the turning being done after it is 
 applied to the shaft, and is suitably counterbalanced. The 
 overhang of the crank is reduced to the least amount 
 consistent with proper strength. 
 
 The crank pin is made of special steel. The hole for 
 the crank pin in the disc is bored after the disc is fitted to 
 the shaft, by means of special machinery, insuring an 
 absolutely true alignment with the shaft. 
 
 These engines are adapted to all classes of service, being 
 used extensively upon Electric Street Railways, Electric 
 Light Stations, Rolling Mills, Paper Mills, Silk Mills, and 
 other miscellaneous industries. 
 
 Opposite page 10 is illustrated a tandem compound con- 
 densing Porter-Allen Engine, having high pressure cylinder 
 40 inches diameter, low pressure cylinder 75 inches diameter, 
 both 66 inches stroke of piston. 
 
 1 1 
 
Porter- Allen Engines 
 
 The low pressure cylinder is supported upon an 
 independent base plate, and is attached by means of heavy 
 tie rods to the hood of the main bed. The high pressure 
 cylinder is bolted to the hood in the usual manner. 
 
 The fly-wheel of this engine is 25 feet in diameter and 
 weighs 180,000 pounds. 
 
 The engine is especially designed for rolling mill service, 
 and couples direct to the roll train. 
 
 The design contemplates a speed of 90 revolutions per 
 minute, and a steam pressure of 150 pounds per square inch 
 at the throttle valve. 
 
 Our standard type of horizontal crank and fly-wheel Air 
 Pump and Jet Condenser is used in connection with this engine. 
 
 We can refer to many examples of these large engines 
 in the Steel Works throughout our Country. 
 
 Opposite we illustrate our Compound Porter-Allen En- 
 gine, adapted to driving electric generators direct connected 
 to main shaft, v/hich practice is now extensively followed 
 in Street Railway and other service.

Porter- Allen Engines 
 
 This class of work is similar to rolling mill require- 
 ments, in that the engine is subjected to sudden and extreme 
 changes of load, and our type is peculiarly fitted to withstand 
 this successfully owing to its massive construction, and the 
 sensitive governor employed, which promptly arrests any 
 fluctuations in speed due to such changes. 
 
 At the same time we give the most refined economy, 
 by reason of our excellent system of steam distribution and 
 method of controlling the same, which is described in the 
 foregoing pages. 
 
 The Delaware Avenue Station of the Electric Traction 
 Company of Philadelphia, of which the cut herewith is a 
 reproduction, is fitted up exclusively with Porter-Allen 
 Imgines, Compound Condensing, there being five in all. 
 
 Four of these engines have a nominal capacity of 1050 
 horse power each, with high pressure cylinder 24 inches 
 diameter, low pressure cylinder 46 inches diameter, by 42 
 inches stroke of piston. The fifth engine is of 350 horse 
 power, with high pressure cylinder 14^ inches diameter, 
 low pressure cylinder 26 inches diameter, by 24 inches 
 stroke of piston. 
 
Porter- Allen Engines 
 
 The large units are designed for a speed of 120 revolu- 
 tions per minute and the small engine 200 revolutions. The 
 generators are of 800 and 250 K. W. capacity respectively. 
 
 The main shaft of the large engines is carried in three 
 bearings, the generator being located between the middle 
 and outer bearings, which latter can be readily taken away 
 to facilitate removal of armature if necessary. 
 
 In the case of the small engine, the shaft runs in two 
 bearings, the generator being attached to the end of the 
 shaft, which is prolonged through the outer bearing for that 
 purpose. 
 
 These engines are liberally proportioned in all their 
 parts, the fly-wheels being very heavy, while the main 
 shafts, bearings, crank pins, etc., are unusually large. In 
 addition to this the whole design is exceedingly compact 
 and occupies a minimum space. 
 
 This plant is only one of many examples we can refer to, 
 having supplied our engines of the Porter-Allen type, both 
 high pressure and compound, direct connected and belted, 
 of various sizes, to some of the largest street railway and 
 power stations. 
 
 U 
 
Porter- Allen Engines 
 
 Our Horizontal Triple Expansion Porter-Allen Engine is 
 shown opposite page 14. The high and low pressure cylin- 
 ders are placed on one side tandem, while the intermediate 
 cylinder acts upon a crank at the other end of the main shaft, 
 which is set at right angles to the high pressure crank. 
 
 The valves in both the intermediate and low pressure 
 cylinders of this engine are arranged and driven the same as 
 those in the high pressure cylinder, excepting they are not 
 controlled by the governor. 
 
 All of the general features of excellence before de- 
 scribed, are introduced in these engines, and special care 
 is taken to make them readily accessible for inspection or 
 repairs. 
 
 The arrangement of cylinders is subject to modification 
 to suit special requirements. 
 
 Our Quadruple Engines are built in the same general 
 style as the last named engine, acting on four cranks, each 
 cylinder single, or on two cranks with two pairs of cylinders, 
 set tandem. 
 
VERTICAL ENGINES 
 
 WE Here illustrate a Vertical Triple Expansion Engine, 
 which can be built to suit any purpose desired. 
 As arranged in the pictures, it is adapted to drive, 
 direct connected to the main shaft, two electric generators, 
 one on each end. 
 
 This type of engine not only possesses the important 
 features of high economy and close regulation, but in com- 
 pactness and accessibility is, we believe, in the lead of all 
 other engines of similar class offered at this time. 
 
 A special patented valve gear is adopted on these engines 
 by which the admission of steam can be regulated from zero 
 to 75 per cent. 
 
 The main bed is a single casting, without external ribs 
 but heavily ribbed internally, provided with ample bearing

 surface for resting on the foundation, and of sufficient rigid- 
 ity to insure perfect alignment of all bearings. 
 
 The bearings, four in number, are solidly bedded in 
 the main bed plate, covered and held by strong cast iron 
 caps. They are so designed that the bottom box can 
 be removed and replaced without lifting the shaft more 
 than the usual clearance between the armature and the 
 field magnets in the dynamos. The boxes are lined with 
 our best Babbitt's metal. 
 
 The shaft is of forged steel, the cranks on the same being 
 formed by cast steel discs, shrunk on and keyed. 
 
 The two outer discs, connecting with the low and inter- 
 mediate cylinders respectively, are united by means of heavy 
 crank pins, forced into the discs and riveted on the back of 
 same. The middle crank pin, connecting with the high 
 pressure cylinder, is inserted and keyed in tapered holes and 
 secured by nuts on the back of the discs. 
 
 The front columns are of hammered iron, turned and 
 polished. To these columns are attached brackets for the 
 valve gear, as well as the front platform. The rear columns 
 are of cast iron, of box section. 
 
 17 
 
Vertical Engines 
 
 The base oi the rear columns is of liberal size where 
 fastened to the bed, and the top extends forward and rests on 
 the front wrought iron columns, thus forming an entabla- 
 ture, to the top of which the cylinders are firmly bolted. 
 
 The back columns carry the guides, which are of ribbed 
 plate pattern. These guide plates also serve as ties between 
 the columns, making a most rigid connection between the 
 same in a direction parallel to the shaft. 
 
 The cylinders are placed, as already implied, with the 
 high pressure cylinder in the center, and intermediate and 
 low pressure on opposite sides of the same. These cylinders 
 are firmly bolted together at the lower end, one flange 
 being recessed, or checked into the other. The upper ends 
 are united by means of loose fitting bolts, thus enabling 
 the cylinders to expand longitudinally at a rate corres- 
 ponding to the temperature oi each one, without disturbing 
 the alignment. 
 
 Each cylinder is provided with four valves, two for 
 admission and two for exhaust. These valves are covered by 
 inflexible covering plates, entirely relieving the valves of any 
 pressure and making them as nearly balanced as is practicable.

Vertical Engines 
 
 The motion for the steam valves of each cylinder is taken 
 from, the connecting rod, the valve gear being of our pat- 
 ented radial type. It consists of a system of rods and levers, 
 joined by means of case hardened and ground steel pins, 
 running in case hardened and ground steel ferrules, thereby 
 reducing the friction to a minimum. 
 
 The admission valve gear for the high pressure cylinder 
 is automatically controlled by a Porter governor, driven by 
 gearing from the main shaft. The admission valves for the 
 intermediate and low pressure cylinders, as well as the exhaust 
 valves for all the cylinders, are adjustable by hand to any 
 desirable degree. 
 
 In the year 1894 we installed in the Harrison Street 
 Station of the Chicago Edison Company, eight of these 
 engines, aggregating a nominal horse power of 7200. Care- 
 ful tests made by disinterested engineers showed an actual 
 water consumption of 13.35 pounds per horse power per 
 hour, and a regulation within i^J per cent, of the normal 
 speed. 
 
 We also build vertical engines simple and compound 
 of this type. 
 
O 
 
 BLOWING ENGINES 
 
 UR Standard Vertical Blowing Engine is illustrated on 
 opposite page. 
 
 We build these engines for Blast Furnace and Bessemer 
 Steel Works' requirements, either simple or compound. 
 
 The engine here shown has a single steam cylinder, fitted 
 with four independent balanced valves of the Porter- Allen type, 
 two controlling the admission and two the release of the steam. 
 
 The admission valves may be controlled either by hand 
 or by our Porter Governor automatically. In the latter case 
 the governor is so arranged as to give a wide range of speeds 
 and thereby meet any conditions that might arise requiring 
 a greater or less number of revolutions. This governing gear 
 is readily adjusted while the engine is running. 
 
SOUTHWARK BLOWING KNGINE 
 

Blowing Engines 
 
 As will be seen, the steam cylinder is placed between 
 the housings, which are strongly ribbed castings, extending 
 from the bed-plate, upon which they rest, up to the lower 
 head of the air cylinder, and containing the cross-head 
 guides. 
 
 The bed-plate is a single heavy casting in which the main 
 bearings are formed. The main shaft which is carried in 
 these bearings, has a fly-wheel fitted on each end. These 
 wheels also act as cranks which are coupled by means of 
 connecting rods to the cross-head. 
 
 The piston-rods, both air and steam, are attached to the 
 cross-head by means of a swivel block, which permits the 
 cross-head to adjust itself to the varying lengths of the 
 connecting rods. 
 
 The bottom air-head rests upon and is attached to the 
 housings as before explained. The air cylinder is placed 
 upon this head, and in turn carries the top head. 
 
 The valves in the top and bottom air-heads are of our 
 patented gridiron type. They give an unrestricted port open- 
 ing of ample area, which permits the air to enter and leave 
 
 21 
 
Blowing Engines 
 
 the cylinder with the least possible friction, thus insuring a 
 maximum discharge per piston displacement. 
 
 These valves have short stroke and move when in equi- 
 librium, thereby reducing wear to a minimum. Those for the 
 inlet of air are operated positively by means of a cam, actuated 
 through the medium of rods and levers by an eccentric on 
 the main shaft, while those for the outlet of air receive their 
 movement from a piston on the stem of the valve, upon which 
 the pressure in the air cylinder, and in the receiver, acts 
 alternately to open and close, and are entirely automatic 
 at any pressure. 
 
 By this system the engine can be run at any speed 
 desired, and further a full movement of all the valves is 
 assured. 
 
 The engine opposite is shown in partly finished state, 
 and embodies all the features heretofore mentioned, but the 
 steam end is made compound, both cylinders acting upon a 
 single crosshead. One of these engines, 32 and 60 inches 
 diameter of steam cylinders, with air cylinder 80 inches diam- 
 eter by 48 inches stroke, is running at the Joliet Works of the 
 Illinois Steel Company. 
 
 22 
 
SOUTHWARK BLOWING ENGINE, COMPOUND CONDENSING 
 

Blowing Engines 
 
 The cut in outline, opposite page 24, represents our Dis- 
 connected Compound Vertical Blowing Engine. As shown 
 it consists of a high pressure engine, having steam cylinder 
 40 inches diameter, air cylinder 72 inches diameter, and a 
 stroke of 60 inches ; a low pressure engine, having steam 
 cylinder 75 inches diameter, air cylinder 72 inches diameter, 
 and 60 inches stroke. These engines are designed to run 
 50 revolutions per minute in regular service, but are built 
 strong enough for a speed of 60 revolutions per minute 
 should the exigencies of the service require it. 
 
 The unique feature of these engines is, that the low 
 
 pressure side is entirely separate and independent of the 
 
 high pressure side, the only connection between the two 
 being the receiver for reheating the steam. 
 
 A Porter governor and link motion controls, automatic- 
 ally, the supply of steam to the high pressure cylinder, and it 
 has been found in practice that the low pressure engine 
 requires no governing device, nor live steam connection, as 
 the supply from the high pressure cylinder is adequate under 
 all conditions of work to cause the engines to run at precisely 
 equal speed. 
 
Blowing Engines 
 
 A system of gate valves is provided so that either 
 engine of the pair can be run separately, condensing or non- 
 coiidensing, as the occasion may demand, which affords 
 every possible convenience in the event of repair. 
 
 The heads of the air cylinders are equipped with our 
 patented gridiron valves as already described. 
 
 The facility with which these engines can be run 
 independent of each other with or without the condenser, 
 by the simple manipulation of the gate valves before men- 
 tioned, coupled with the economy due to compounding, 
 when run as a pair, has made this dis-connected type very 
 popular ; one Steel Works alone having purchased six pairs 
 of these engines in the last two years. 
 
 A Southwark Horizontal Independent Crank and Fly- 
 wheel Air Pump and Jet Condenser is used in connection 
 with this engine. 
 
 Opposite page 26 is illustrated a battery of Vertical 
 Blowing Engines consisting of ten engines, each having a 
 steam cylinder 42 inches diameter, air cylinder 84 inches 
 diameter, both 60 inches stroke of piston. 
 
Blowing Engines 
 
 They are located in the engine room of Furnaces 5, 6, 7 
 and 8 of the South Chicago Works of the Illinois Steel 
 Company, where they have been in operation for the past 
 six years. 
 
 These engines were all built by our Company. 
 
 The two pictures following page 28 are from photo- 
 graphs taken in the Works of the Cleveland Rolling Mill 
 Co., Cleveland, Ohio, and represent our Improved Horizontal 
 Automatic Twin Bessemer Blowing Engine, with steam 
 cylinders working on cranks set at right angles on the 
 shaft, and a fly-wheel applied in the middle of the shaft; 
 each steam cylinder having its own air cylinder placed 
 in a straight line behind it. 
 
 The steam cylinders in this case are 44 inches diameter 
 and the air cylinders 60 inches diameter, by 60 inches 
 stroke of piston. 
 
 The steam cylinders are of the Porter -Allen type, 
 having four balanced valves, those for admission in each 
 cylinder being controlled automatically by a Porter Governor 
 and link motion. 
 
Blowing Rngines 
 
 The air heads are fitted with our patented oscillating 
 gridiron valves. Those for inlet of air are operated posi- 
 tively by a cam motion, while the outlet valves are operated 
 by special cylinders and valve motion for same, which cause 
 them to open and close automatically according to the air 
 pressure it is desired to blow into the converters. 
 
 An important feature of these valves is the fact that 
 when they are in motion they do not touch their seats thus 
 preventing all wear. One set has been in constant use at 
 the works of the Cambria Iron Co., Johnstown, Pa., for a 
 period of six years, and are as good as when first applied. 
 
 The bed plates of these engines are of massive pro- 
 portions, extending from and including the main bearing 
 to the steam cylinder. 
 
 Heavy tie rods connect the air cylinders to the beds, in 
 addition to which a further support is given these cylinders 
 by substantial sole plates, extending under and attaching to 
 the steam cylinder. 
 
 We also build these engines with compound steam 
 cylinders, adapted either to Blast Furnace or Bessemer work.

 COMPRESSORS FOR NATURAL GAS 
 
 NK of the uses to which our improved gridiron valve 
 has been successfully applied, is the pumping of nat- 
 ural gas. 
 
 Its great durability and positive action makes it pecu- 
 liarly fitted for this class of work. We illustrate opposite 
 page 30 one of these Compressors, having compound steam 
 and gas cylinders, arranged with a system of valves so as 
 to run both gas cylinders high pressure as well as com- 
 pound, or either side as a single engine. 
 
 To show the efficiency of this air gear we would state 
 that these engines run night and day at 60 revolutions per 
 minute, and work equally well from 3 pounds to 100 pounds 
 gas pressure. 
 
 29 
 
Compressors for Natural Gas 
 
 The gas cylinders are effectively water jacketed, and when 
 running compound, in passing from the low pressure to the 
 high pressure cylinder, the temperature of the gas is reduced 
 by the use of an efficient cooler. 
 
 The general design of these compressors is the same as 
 our horizontal blowing engines, and we shall be pleased to 
 furnish prospective purchasers with full information and 
 prices.

 REVERSING ENGINES 
 
 UR type of Reversing Engine for Blooming Mills, 
 shown in outline drawing, has been used in the Steel 
 Works for a long time. 
 
 We can refer to examples at the Works of the Cam- 
 bria Iron Co., Johnstown, Pa. ; Carnegie Steel Co., Pittsburgh, 
 Pa. ; Otis Steel Co., Cleveland, Ohio; Pennsylvania Steel Co., 
 Steel ton, Pa. ; Potts town Iron Co., Potts town, Pa. ; Spring- 
 field Iron Co., Springfield, 111., and Wheeling Steel Works, 
 Wheeling, W. Va. All of these engines are of large size, 
 ranging from 28" x 48" to 44" x 60" cylinders. 
 
 The design is massive and intended to withstand the 
 heaviest shocks common to this service. The steam cylinders 
 are rigidly attached to the beds, and are fitted with a single 
 double-ported balanced slide valve, driven by eccentrics on 
 the main shaft. 
 
Reversing Engines 
 
 The reversing links are operated by an hydraulic engine 
 placed between the bed-plates, and controlled from the work- 
 ing platform, which is placed in a convenient location. 
 
 The throttle valves are also operated from this platform. 
 
 The bed-plates are an adaptation of the design used 
 in our Porter-Allen Engine, which we believe is the best 
 form yet devised for engines subjected to severe and contin- 
 uous strains. 
 
 The gearing is of steel, the pinion being cast solid, while 
 the rim of the spur wheel is fitted to a cast-iron spider to 
 facilitate renewal. 
 

CENTRIFUGAL PUMPS 
 
 WE make a specialty of Centrifugal Pumps for Dry 
 Dock, Drainage, Irrigation, Sewerage and other 
 purposes, where a large quantity of water is required 
 to be quickly handled. 
 
 We claim the distinction of being the first concern in the 
 United States to build this class of pump in the large sizes, 
 and are pleased to refer to the following Government Dry 
 Docks which we have equipped with our machinery: 
 
 UNITED STATES NAVY YARD, Mare Island, Cal. 
 
 " " " Portsmouth, Va. 
 
 League Island, Pa. 
 
 Brooklyn, N. Y. 
 
 Boston, Mass. 
 UNITED STATES NAVAL STATION, Port Royal, S. C.

Centrifugal P^wnps 
 
 In addition we have equipped the following private docks : 
 
 NEWPORT NEWS SHIP BUILDING & DRY DOCK COMPANY, 
 Newport News, Va. 
 
 CLEVELAND DRY DOCK COMPANY, 
 Cleveland, Ohio. 
 
 CHICAGO SHIP BUILDING COMPANY, 
 Chicago, 111. 
 
 Where the lift is not excessive, this type of Pump is 
 admirably adapted for pumping sewage and drainage water, 
 and we have built a large number for that purpose. Promi- 
 nent among the places where our plants can be seen in 
 operation in this service are City of Philadelphia, Pa. ; 
 City of Chicago, 111.; City of Stamford, Conn. 
 
 Besides which, we have built a great many of various 
 sizes for private parties. 
 
 We illustrate opposite two of these pumps having dis- 
 charge openings 42 inches diameter, each pump being driven 
 direct by a vertical engine, 28 inches diameter 01 cylinder 
 and 24 inches stroke of piston. 
 
 A portion of the piping and gate valves is also shown, 
 applicable to dry dock service. 
 
 34 
 
Centrifugal Pumps 
 
 This size of pump has a nominal capacity ot 40,000 
 gallons of water per minute, but has shown on repeated 
 tests an actual discharge of over 50,000 gallons per minute. 
 
 We quote from the official report of the test made 01 
 the first pair of these pumps built by us for the United States 
 Government. These pumps were installed at the Dry Dock, 
 U. S. Navy Yard, Mare Island, Cal., in 1885 : 
 
 Extracts from the Report. 
 
 "Contract requirement, a mean discharge of 80,000 gal- 
 lons per minute from both pumps." 
 
 "Actual mean discharge from both pumps 112,922 
 gallons per minute." 
 
 "Greatest discharge, 137,797 gallons per minute." 
 
 In transmitting a copy of the report to us, the Bureau ol 
 Yards and Docks wrote as follows : 
 
 " The Bureau in forwarding a copy of the report, desire 
 also to congratulate you upon the successful and unprece- 
 dented performance of the pumps." 
 
 35 
 
Centrifugal Pumps 
 
 The official tests made of our machinery at the other 
 Government Dry Docks, subsequent to the above, have shown 
 results equally satisfactory. 
 
 A convenient and compact arrangement of pump and 
 engine is shown opposite. 
 
 This design contemplates a single bed- pi ate, common to 
 pump and engine, the fly-wheel acting as a coupling between 
 the crank and runner-shafts. 
 
 We have suppled them in this form for drainage service 
 at the various dry-docks, and for other purposes where a self- 
 contained pump was preferred. 
 
 Where an electrical current is available, an economical 
 method of driving Centrifugal Pumps, especially of the smaller 
 sizes, is by means of a motor coupled direct to the runner-shaft, 
 and we have designed and built them in this manner, combin- 
 ing the pump and motor on a bed-plate common to both, as 
 per second illustration following. 
 
 This arrangement is particularly applicable where the 
 pump is located at a distance from the boiler plant, as it avoids 
 the running of long steam pipes, and the consequent condensa-

 tion, or the necessity for additional boilers with increased 
 attendance, and provision for handling coal and ashes at the 
 site of the pump. The simple running of the wires being all 
 that is required in the case of the electrically driven pump. 
 
 Where steam is used to drive these pumps, it has been 
 found desirable to furnish a plain high pressure engine, if 
 the service is intermittent, like in dry docks, as the saving 
 in first cost is more to be considered than a refined economy 
 in steam consumption. 
 
 This condition only applies, however, to cases where the 
 machinery is operated but a short time at long intervals. 
 
 If the pumping is constant, or nearly so, we recommend 
 a refined economical steam engine for the work, and have 
 usually supplied compound or triple expansion engines. 
 
 A plant for constant service is shown opposite page 38. 
 It consists of three pumps, having discharge openings 24 
 inches diameter, each direct driven by a Compound Condens- 
 ing Porter- Allen Engine, with cylinders 12 inches and 22 
 inches diameter by 24 inches stroke of piston. 
 
 The combined capacity of these pumps is 72,000,000 
 gallons every 24 hours. 
 
 37 
 
Centrifugal Pumps 
 
 This plant was installed by our Company in the South 
 Chicago Works of the Illinois Steel Company, and supplies 
 water for their Blast Furnaces and other purposes. 
 
 It has been in operation over five years, and careful tests 
 have shown a high degree of efficiency. 
 
 We can also refer to similar plants at the Works of the 
 Cambria Iron Company, Johnstown, Pa., Pottstown Iron Com- 
 pany, Pottstown, Pa., and the Johnson Company, L/orain, Ohio. 
 
 Careful attention has been observed by us in designing 
 these pumps to maintain uniform water ways throughout. 
 The runner is of the double enclosed type, the suction entering 
 by easy turns at each side, thus effectively balancing it and 
 avoiding all lateral thrust on the shaft. 
 
 The runner-shaft is liberally proportioned to insure perfect 
 rigidity in working, and is carried in bronze bearings, which 
 are lubricated automatically while the pump is in operation, by 
 the water being pumped. 
 
 The casing is constructed so as to provide for the ready 
 removal of the runner, without disturbing the joints in the 
 suction or discharge pipes. 
 
Centrifugal Pumps 
 
 The design of our casing also permits of the suction 
 entering and the discharge leaving the pump in any direction 
 desired. 
 
 It is very essential in this type of pump to pay careful 
 attention to the interior construction. We not only design 
 all parts liberally, which makes our pumps larger, size for 
 size, than any others in the market, but also machine the 
 runner all over, thereby completely balancing it, and thor- 
 oughly clean all the passages, coating the same with iion-cor- 
 rosive paint. 
 
 The pumps already described are what is known as the 
 horizontal pattern, the shaft being in a horizontal plane. 
 
 We also make Centrifugal Pumps of the submerged type, 
 having the shaft in a vertical position. 
 
 An illustration of one of these pumps is given opposite 
 page 40. 
 
 While this style of pump is not so accessible for examina- 
 tion as the other style, yet there are certain situations where 
 they can be used to greater advantage. 
 
 The principal points in its favor are the absence of all 
 
 39 
 
Centrifugal Pumps 
 
 suction pipes and the fact of its being constantly primed ready 
 for operation. 
 
 We have lately completed for the United States Govern- 
 ment a plant consisting of three submerged pumps, with 
 discharge openings 30 inches diameter, and one 10 inches 
 diameter. 
 
 These pumps are located in the new Soofoot Lock at 
 St. Marys Falls, Mich. 
 
 We build our Centrifugal Pumps in sizes from 8 inches 
 to 42 inches diameter, and are prepared to undertake the 
 engineering and complete installation of plants for all classes 
 of service.

O 
 
 WATER WORKS PUMPING ENGINES 
 
 NE of the important branches of our business, is the 
 designing and building of High Duty Pumping 
 Engines for Water Works. 
 
 Our experience in this field, coupled with the excellent 
 facilities we possess for handling heavy work, enables us to 
 construct these engines of the largest sizes. 
 
 The illustration opposite page 42 is of a Vertical Com- 
 pound Condensing Crank and Fly-wheel Pumping Engine, 
 having a capacity of 15,000,000 gallons every 24 hours. 
 
 This type of pump is very convenient and accessible for 
 operating, and occupies comparatively small floor space. 
 
Water IVorks Pumping Engines 
 
 The dimensions are as follows : 
 
 High Pressure Steam Cylinder, 44 inches diameter. 
 Low Pressure Steam Cylinder, 88 inches diameter. 
 Two Water Plungers, 28 inches diameter. 
 All 42 inches stroke. 
 
 In many cases it is necessary to design a pump to occupy 
 a limited space, a condition which frequently occurs in re- 
 modeling or enlarging old Water Works. 
 
 We have repeatedly been called upon to meet cases ot 
 this kind, and the second plate following is an example of a 
 special pump of this character, two of which we have built. 
 
 This cut shows a High Duty Twin Compound Condens- 
 ing Crank and Fly-wheel Pumping Engine, in which the 
 steam cylinders are placed vertically, while the water cylinders 
 are horizontal. 
 
 The design of this pump was made necessary by reason 
 of the available space being too small for a horizontal engine, 
 and the situation not permitting of a pit for a vertical engine. 
 
 As will be seen in the cut, the motion of the steam pistons 
 is transmitted to the water plungers through rocking beams.

 HIGH DUTY PUMPING KNGINK 
 
IVater Works Pumping Engines 
 
 The design is massive, and has proven to be a very efficient 
 one. Its capacity is 20,000,000 gallons every 24 hours. 
 
 The increasing demand for higher duty in Water Works 
 Pumping Engines has compelled the adoption in many in- 
 stances of the Triple Expansion type, and we present an 
 outline sectional elevation of one of four 2O,ooo,ooo-gallon 
 pumps designed and built by us on these lines. 
 
 A reference to the cut will show many unique features, 
 prominent among which is the absence of the usual masonry 
 foundation ; in its place is a plate steel substructure which 
 while of ample stiffness, affords unusual access to all parts of 
 the water end. 
 
 The dimensions of the Triple Expansion Pumping 
 Engine referred to, are as follows : 
 
 H. P. Cylinder, 37 inches diameter. 
 
 I . P. Cylinder, 62 inches diameter. 
 
 L. P. Cylinder, 96 inches diameter. 
 
 Water Plungers (three), 34^2 inches diameter. 
 
 All 54 inches stroke.

Heater Works Pumping Engines 
 
 We are prepared to submit designs of Pumping Engines 
 for Water Works to meet any requirement, and shall be 
 pleased to consult with Cities or private parties, when con- 
 templating the purchase of such machinery.

GENERAL 
 
 IN addition to the specialties already treated upon, we 
 would explain that we have built Hydraulic Bloom 
 Shears, Intensifiers, Ingot Extractors, Charging Machines, 
 Hydraulic Pressure Pumps, Hydraulic Presses and other 
 miscellaneous work of heavy and special character. 
 
 We solicit inquiries in this line ; also for castings of any 
 size and weight up to 100,000 pounds. 
 
 We illustrate, as an example of heavy boiler work, a 
 battery of four Marine Boilers, each u feet 9 inches diameter 
 by 10 feet 10 inches long, built by us for the City of 
 Philadelphia. We have furnished twenty-three of these large 
 boilers to this city alone, besides having supplied them 
 equally large with our Dry Dock Pumping Plants. 
 
 45 
 
General 
 
 We also illustrate as an example of heavy machine work, 
 a Disappearing Gun Carriage, two of which we built for 
 the Ordnance Office of the U. S. Army. These carriages, the 
 first of their kind, were ordered by the Government as an 
 experiment. When completed by us and delivered to the 
 U. S. Proving Ground, Sandy Hook, N. J., they were 
 subjected to the most severe tests and withstood the same 
 successfully. The material of these carriages, was the best 
 open hearth steel throughout, and the specifications called 
 for a most refined and accurate finish. Every detail was 
 examined critically by the Government Inspectors, and 
 passed upon as a perfect piece of work. 
 
 We can point to many other examples of our facilities 
 for handling varied work of large character, and of a nature 
 requiring accurate workmanship and best materials.
