It has been our aim in this book to present graphically a description of the several types of machinery we build, and we trust you will find it an especially valuable reference. That we may know each copy reaches safely those to whom it is sent, an acknowledgment will be ap- preciated Very truly yours, Southwark Foundry & Machine Co w g of MS * w i * g s g - rt j General Catalogue of the Southwark Foundry and Machine Co, Sole Makers of the Porter-Allen Automatic Engine Also Builders of Vertical Engines Blowing Engines Reversing Engines Centrifugal Pumps Water Works Pumping Engines Boilers and Tanks and Other Heavy and Special Machinery Office and Works Washington Avenue and Fifth Street Philadelphia 1896 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 4 W a PU o if > 2 r v: 2 1 O 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. 33 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- 36 SOUTHWARK CENTRIFUGAL PUMP AND ENGINE DIRECT COUPLED AND MOUNTED ON A COMMON BED-PLATE M O PC S " 2 n ^-; ^ jc > *> *? c 5 Q w > O s Centrifugal Pumps 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. 40 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. 42 SOUTHWARK COMPOUND CONDENSING CRANK AND FLY-WHKEL 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. 43 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.
