L IFTING AND FORCE PUMP.

.- SPEOIFICAIION forming part of Letters Patent No. 224,509, dated February 17, 1880.

' Application filed November 3, 1879. A I

tain new and useful improvements in that class of Water-elevators knowp as lifting and force pumps, wherein great economy, durability, and efficiency are required.

The invention consists in the peculiar construction, combination, and arrangement of parts, as more fully hereinafter set forth.

In the drawings, Figure 1 is a vertical cen tral section. Fig. 2 is a detached and perspective view of the barrel. Fig. 3 is a detached and perspective view of the section above the barrel, forming a water and valve chamber with offset discharge-neck and attachments. Fig. 4 is a like view of the upper piston-chamber.

Like letters refer to like parts in each figure.

In the accompanying drawings, which form a part of this specification, A represents a pump barrel or cylinder with an open or perforated bottom, and with a flange top, a, provided with a central opening, b, which forms a seat for the double valve B, which is sleeved on thepiston-rod 0. Within this barrel the hollow piston D reciprocates, and is provided with annular channels 0 to form water-pack ing. Seated upon the top of this hollow piston and sleeved upon the piston-rod C is the valve F, the throw or play of which is controlled by the stop don the piston-rod. This valveB is a double fone-that is to say, it is composed of an upper and lower'valve connected by a hollow neck,the lower valve having its seat in the fiangetop a of the barrel. G is a short cylinder fitting by a ground joint upon this flange top, and is provided with an outlet-pipe, H, the outer end of which terminates in an enlarged recess, 0, the vertical walls of which are threaded to engage with thebottom of the externally-threaded shell I.

A valve-seat, f, is formed within this recess to receive the valve J. The spider K is placed over this valve, its foot-ring gresting upon the bottom of the recess being ground to place, andthe shell I being screwed to place secures the spider. a

L is a cylinder" fitting with a ground joint upon the top of the cylinder G. This cylinder isprovided with an internally and externally projecting flange, h, and'by means of bolts is secured to the flange top of the barrel. The internally projecting portion of the flange leaves a contracted opening into the bottom of the cylinder, in which there is a seat for the upper valve of the double valveB, heretofore described.

Below the hollow piston N, which reciprocates within the cylinder L, which is open at 7 top, the valve M' is sleeved upon the pistonrod, and has its seat on the under side of the piston, its throw being confined by the stop 6.

The upper end of this piston-rod is threaded sisting of the barrel A, double valve 13, pistonrod-C, hollow piston D, valve F, cylinder G, outlet-pipe H,-shell I, valve J, spider K, cylinder -L, valve M, hollow piston N, and pitman-connection 0, when the parts are constructed and combined to operate substantially as shown and described.
