IMPROVEMENT IN PUMPS.

Speeiiication forming part of Letters Patent No. 216,877, dated June 24, 1879; application filed July 23, 1877.

To all whom it may concern:

Be it known that I, GEO. W. MCKENZIE, of Harrington, in the county of *Washington and State of Maine, have invented a new and Improved Pump for Cisterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a perspective view; Fig. 2, a vertical section; and Figs. 3, 4, and 5 are different forms of levers for operating said pump.

I make the pump case or cylinder, A, Fig. 1, preferably, in rectangular form, of plank or boards firmly bolted together. The bottom B and top O are held rmly in place by the screw rods a., which pass through the projecting cross-pieces b and the top O.

In Fig. 2, D is the cylinder; E, the piston; F, the induction-port, and Gr the dischargeport. The ports F and Gr each consist of two narrow openings, with valves c and d, the valve d being hinged vertically.

H is the discharge-chamber, with which the discharge-pipe N is connected.

In Fig. 3, L is the sink; M, the treadle or foot-lever, the inner end of which is lpivoted to the base-board beneath the sink, and the outer end projects several inches beyond the front of sink, and works-'up and down in a slot therein.

P is the piston-rod, which passes through the floor and is connected with the treadle M. S is a spring, which may be of any shape or material, secured beneath the floor, and one end of which is attached to the piston-rod.

When it is required to place the pump several feet away from the sink the lever l, Fig. 4, may be added, and connected to the treadle M by the link o, passing through the door.

"he pump may be placed any distance from the sink by the use ofthe pulleys J and J Fig. 5, connected by the wire K, which passes over the pulley J and under J", one end being attached to the link o, and the other to the piston-rod.

The operation of thepump, as thus described, is as follows: The foot is placed on the lever M and pressure applied, when the piston E descends, the pressure of Water closing the induction-port F and opening the dischargeport G, allowing the water to escape into the chamber H and up through the dischargepipe N. On relieving pressure of foot from lever, the piston is raised by the action of the spring S, port G closes and port F opens, allowing' a new supply to be drawn into the cylinder.

It is evident the above-described pump is .particularly adapted to cisterns; butI do not GEORGE W. MGKENZIE.-
