Patented Jan. a, tea 2.

Application filed May 12, 1911. Serial No. 626,686.

To all whom it may concern:

Be it known that I, ARTHUR B. JENNINGS,

a citizen of the United States, residing at Hazleton, county of Luzerne, and State of Pennsylvania, have invented certain new.

and useful Improvements in Pumps, fully described and represented in the following specification and the accompanying. draw- 1ngs,'form1ng a part of the-same -The object of the present invention is to provide an improved pump construction of that class in which the pump capacity is divided between a number of inlet and outlet valve pipes and connections, which shall avoid the use of complicated patterns and otherwise be simple of manufacture and more convenient in usethan previous con structions of this class. 3 y

The construction is especially adapted for high pressure pumps made entirely of steel castings, in which'the difficulty of casting soundly from complicated patterns has been a source of great trouble and expense in making from steel castings the complicated valve pots and other parts heretofore used in such pumps. The invention may be applied, however, to other pumps than those made of steel castings.

. For a full understandingof the invention,

a detailed description of a duplex pumping engine embodying the invention in the preferred, form will now be given-in connection with the accompanying drawing form-v I ing a part of this specificat on and the fea- 'tures forming the invention then specifically fpointed out in the claims.

In the drawings Figure 1 is a side elevation of the pump, and Fig. 2 is a 'transverse sectional elevation, the section being taken through the suction and force valve chambers on one side. 7 1

In the drawing, which shows a pump of the well known outside packed plunger type,

A are the plunger-chambers or pump cylinders, in which work the end plungers B.

These plunger chambers carrya number of flanged connections 10 on which are 'mount- I ed Ts C to which are connected elbows D and E forming respectively the suction and force valv chambers. The suction valve chambers D connect through elbows F and connections 12 with suction manifold G, and force valve chambers E connect with force manifolds H through connections 13.

which aids materially in securing the de' sired simplicity and convenience of manu- .f I

facture and removal of parts, and this is the preferred construct on.

-Within the elbow valve chambers D, E, are mounted respectively the suction valves- (4 and discharge valves 6 on their seats 0, the valves being provided with flanges 1 held between the flanges on the-elbows and parts to which they are connected, the flanges 1 being seated in notches in the opposing parts. The elbows D, E are preferably provided withshoulders 2 fitted Within corresponding shoulders-3 on the parts to which they are connected at their outlet ends, so that the elbows are held firmly in proper position when the fiangesjare bolted together, and for the purposev of allowing 't he elbow's to be withdrawn to release these shoulders and allow thev elbows-to be lifted. from the arts C, F a' small amount of sidewise play is allowed, between thecva'lve flanges land the elbows or connectingparts,

so that the valve chambersmay be movedsidewise to withdraw the shoulders 2, 3 from engagement. after which withdrawal the elbows may be lifted oil with the valves.

'- It will be seen that the invention provides a pump construction much more'iubdivided than has heretofore been attempted, secur- I ing a very simple and convenient construction and avoiding all complicated patterns.

What I clalm 1s:

1-. A pump having a number of Rs mounted on the pump chamber, elbow suction and force valve chambers connected to the Ts, and suction and discharge manifolds connected: to the valve chambers, said elbow valve chambers being made removable for access to the valves. I p

2. 1A pump having a number of Ts" mounted on the pump chamber, elbow suction and I force valve chambers connected to the Ts,

and suction and discharge manifolds connected to the valve chambers," said elbow valve chambers being made removable for access to the valve and the suction and force valve chambers being interchangeable.

{3. Apump haying a number of'Ts mountforce valve chambers connected to the valve ed on the pump chamber, elbow-suction and force valve chambers connected to the Ts, suction and discharge manifolds connected to the valve'chambers, and a valve in each chamber having a flange held in position between the valve chamber and connecting part, said elbow-valve chambers being made removable for access to the valves.

4. Apump havinganumber of Ts mounted on the pump chamber, elbow suction and I rchambers, suction and discharge manifolds shoulders on the opposite ends of the valve.

chambers and parts with which they connect released by the sliding movement of the valve chambers to permit the removal of the valve chambers. g

. 5', A pump having the plunger chamber A a with connections 10, Ts C on said connections, elbow suction and force valve chambers D, E, valves a, b in said chambers, suctlon and force manifolds G, H, and -connections between said valve chambers and manifolds. w i

In testimony whereof, I have hereunto set my hand, in the'presence of two subscribing witnesses.
