BENJAMIN S. CHURCH, OF NEW YORK, N. Y.

IMPROVEMENT IN PUMP-COCKS.

Specification forming part of Letters Patent No. 154,319, dated August 25, 1874; application filed May 29, 1874.

1 0 all whom it may concern:

Be it known that I, BENJAMIN S. CHURCH, of New York city, State of New York,'have invented a Pump-Cock, of which the following is a specification:

The object of my invention is to attach to the discharge or supply opening of a cook a pump, A B, as shown in Figure 1 of the accompanying drawing, to draw water into handbasins, bath-tubs, closets, &c., on stories above the height to which the water rises in the service-pipes, or where the flow of water may be intermitted.

The machine is illustrated more in detail in the accompanying drawing, in which Fig. 1 is a vertical longitudinal section, and Fig. 2 is a section and projection through T T of Fig. 1. Fig. 3 is a longitudinal section on line w m, Fig. 1.

The parts in both figures being lettered alike, the description is as follows;

A and B are cylinders; C and D, their pistons. F F F F are valve-boxes. E E E is a partition separating the inlet-water from the outlet-water in each valve-box. At the ends of this partition are the stuffing-boxes N N for the piston-rods. KK is a port connecting the inlet-water of the valve-boxes, and K (behind KK in Fig. 1) is a portconnecting the outletwater in the valve-boxes. Through these two ports two rods, L L L, pass, one end of each rod being screwed into the front of valve-box F F, and the other ends pass through the head of valve-box F F and into nuts 'on the outside, which being tightened, the rods bind all the parts of the pump together. 1 1 1 1 are the inlet-valves, and 2 2 2 2 the outlet-valves, of the cylinders.

The pistons moving in the direction of the arrows, the action is as follows: The water entering through G, opening valve 1, enters cylinder A, (Valve 1 closing.) It enters, also, through K K, into valve-box F F, and, opening valve 1, enters cylinder B. Simultaneously the water is forced out of cylinder A, through valve 2, into valve-box F F, and then out through H. The water is forced out of B, through valve 2, port K, (situated behind K K, Fig. 1,) into valve box F F, then out through H. On the return stroke of the pistons the action of the valves is reversed.

When there is sufficient pressure in the service-pipe to raise the water to this cook, it can flow through the valves and out of H unobstructed and without working the pump.

My invention may be attached to the supply-pipe by any of the ordinary methods of attaching a cook or faucet to such pipe.

I claim as my invention 1. The combination of a pump, faucet, and supply-pipe, substantially as and for the purpose described.

2. The combination of the valve-boxes F F F F and their valves, the partition E E E, the ports K K K, substantially as described.

3. The combination of the valve-boxes F F F F and their valves, the partition E E E,

the ports K K K with a supply-pipe, substantially as and for the purpose described.
