srncirrdndilon forming 15m of Letters Patent No. 657,976, dated september 1s, 1900. Applica-tained october 4, 189s. senin No. 692,660; dto meer.)
To LZZy whom t may concern.-
Beit known that I, CHARLES C. WORTH- NGToN, a citizen of the United States, residing at Irvington, county of Westchester, and State of New York, have invented certain new and useful Improvements in Pumps,fully described and represented in the following specification and the accompanying drawings, forming a part of the same. 1 This invention relates especially to duplex steam-pumps, the chief object of the invention being to provide an improved construction of this class which shall be of such compact form as to secure a high capacity with a pump of small size, and,further, to provide sucha pump which shall be simple, cheap, and durable in construction, convenient for forming the required pipe connections, and which shall present an improvedv appearance over such pumps now in use.
In attaining the objects above stated I have made certain improvements in the water end of the pump, and the invention includes certain features in the construction of duplexpump cylinders and their chambers and connections, all as fully described hereinafter and specifically pointed out in the claims.
For a full understanding of the invention a detailed description of a construction em,- bodying all the features of the invention in their preferred form as applied to a duplex direct-acting steam-pump of' a well-know class will now be given in connection with the accompanying drawings, in which- Figure l is a vertical longitudinal section of the pump,taken on the line l of Figs.` 2 and 5. Fig. 2 is a horizontalsection on the line 2 of Fig. l.
4 of Fig. 1. on the line 5 of Fig; l. longitudinal section on the line 6 of Fig. 5.
Referring to the drawings, A A are the steam-cylinderson opposite sidesoffthe engine, and B Bthe correspondingfwat'er-cylinders. The steam andwater cylinders are preferably connected,` as'. shown, byn the side frames C and central-fralne-piece D,`formed integral with the steam end and connectedato the water end by the usual flange connection, the central frame-piece D forming the cradle on which the valve-movement is mountedvand Figs.4 3 and t are vertical crosssections of the steam end on the lines ,StandI Fig. 5 is a vertical cross-section Fig.l 6 is a vertical A l l end, openingb'eyond the cylinder ends into cradle D are preferably formed integral, as.
shown, so that a single casting forms the steam end and'cradle, with the exception of l the valve-chest.v
The steam-cylinders are shown as having the usual pistonsa, connected by piston-rods b directly to the pump-plungers o on opposite sides of the engine, and the usual inductionports dd and exhaust-ports e e'4 for the respective cylinders A A', communicating, ref spectively, with the single steam-chest Eon top of the cylinders and with the exhaustcove f by exhaust-ports g g', all these portsv being shown as controlledfor admissionand exhaust by the D slide-valves h h' o n the respective cylinders, although it will be .understood that the'forrn and arrangement of these 'valves and ports may be varied as-desired.
It will be understood that the valves h h maybeactuated by any suitable moveme As shown, they are actuated by the usual crossover valve-movement H, mountedon the cradle D, as previously described, and connected to the valves h h by links l1 and valve- `rodsv 12, so that the valve 011 each side is op-4V erated from the other side of the-engine, as usual in duplex direct-actinglengines of the class shown; :The induction-pipe F may be and is .shown asconnected directly with the steam-chest E at the end of the pump, as
usual in such constructions.
The exhaust-cove f, which extends across both ports g g', as shownin Figs. 2 Vand. 3, connects centrally with an exhaust-'passage which preferably is made narrow horizon-v gtally, as shown, for compactness of construc- Qtion, and .extends downward between the steam-cylinders A. A and toward the pump ya"charnber,shown asv formed byan eXten- .sion of the cylinder-casting and enlargement of the cradle'D.- 'Withthis chamber I the eX- baust-pipe G connects .by port la'. The portl r lo preferably opens vertically from the chamber I, either upward or downward; but it will be understood that this may be varied. As shown, the pipe G is above the chamber and a second port k opens downward` from the chamber I, and this construction ispreferablyi used, so that the exhaust-pipe G may extend either upward or downward, as may be found more desirable in setting up the pump, the port 7s to which the exhaust-pipe G is not conneeted being then closed in any suitable manner, as by a cover 10, shown on the lower port 7c in the drawings.
Referring now to the water end of the pump, the water-cylinders B B on opposite sides are preferably cast integral with each other and with the pulsation-chambers and suction and force passages, as shown, a very com pact, cheap, and durable construction being thus provided which in itself forms a specific part of the invention; but it will be understood that the broader features of the invention are not limited to this integral construction.
The suction-passage L for both cylinders B B extends upward from below in a plane between the cylinders, so that its flange 13 for connection with the suction-main is at the end of the pump below and between the cylinder-heads 14, and this suction connection L expands horizontally above the cylinders into a broad suction-chamber Z, preferably of small depth, as shown, from which the suction passes through suction-valves m m for the respective cylinders, which valves may be of any common or suitable form, into the respective pulsation-chambers n n and n n for the opposite ends of the respective pump-cylinders and opening downward into the latter. These chambers are formed by the longitudinal and transverse partitions 1 2. Above the pulsation-chambers n n and formed, as shown, by a separate hood-casting bolted onto the top of the cylinder construction is the force-chamber K, into which the fluid is forced through force-valves o o' for the respective cylinders, which may be of any common or suitable form. These valves 0 o are mounted on the valve-plate 15, and the force-passage M opens through this valveplate centrally between the valves o o and extends down through the casting of the cylinder construction centrallybetween the pulsation-chambers n n and valves m m', its walls being formed by portions of the partitions 1 2. Below the pulsation-chambers it passes downward as a pipe through the suction-chamber Z and between the cylinders, where it is contracted sidewise and expanded vertically to secure the desired capacity with compactness in the arrangement of the cylinders and force-passage and then extends upward, resuming its circular form, and passes between the rear pulsation-chambers n n' and then outward to the end of the pump, with its connecting-flange 16 above and between ,the cylinder-heads lll and in line with the lian ge 13 of the suction-passage L, thus brin ging all the flanges for the cylinder-heads and suction and force connections into the most convenient position for rapid and accurate facing in manufacture.
As shown, four suction and force valves are used, one for each pulsation-chamber, and
the force-passage M is formed square where it passes between the valves, so as to secure the most compact arrangement of valves and force-passage. It will be understood, however, that the number of valves may be varied and that the force-passage may be of other form. The suction-passage, however, will preferably be made angular in cross-section vto correspond with the number of valves employed for compactness of construction.
It will be seen that my invention provides a very simple, convenient, and compact duplex-pump cylinder construction.
While the features forming the present invention are preferably used in a duplex direct-'acting steam-pump, as shown, one object of the present invention being to provide such a pump of very small size for its capacity, it will be understood that my improvements in the pump end may be used in any class of pump, with the pump-plungers operated di-` rectly by steam-pistons or in any other manner. fications in the construction shown may be made by those skilled in the art without departing from the invention and that I am not to be limited to the exact form or arrangement of parts shown in the drawings.
What I claim is- 1. A pump having two pump-cylinders arranged side by side with the force-chamber above the pulsation-chambers and the forcepassage extending downward centrally between the pulsation-chambers and suctionvalves to a plane below the suction-valves and then upward and outward to open at the end of the pump above and in a plane between the cylinders.
2. A pump having two pump-cylinders arranged side by side with the force-chamber above the pulsation-chambers, the suctionpassage entering at the end of the pump below and in a plane between the cylinders and passing upward between the cylinders to form a suction-chamber above and between the cylinders below the pulsation-chambers, and the force-passage extending downward centrally between the pulsation-chambers and suctionvalves to a plane below the suction -valves and then upward and outward to open at the end of the pump above and in a plane between the cylinders.
3. A pump having two pump-cylinders arranged side by side with the force-chamber above the`pulsation-chambers and the forcelpassage extending downward centrally between the pulsation-chambers and suctionvvalves into the suction-chamber and between the cylinders and then upward and outward to open at the end of the pump above and in a plane between the cylinders.
4. A pump having two pump-cylinders arranged side by side with the force-chamber at the top of the pump and the force-passage extending downward centrally between the suction-valves of the two cylinders to a plane `below the valves and then to the discharge.
