PUMP.

SPECIFICATION forming To all 'whom zt may concern: A

Be it known that I, JOHN HARRIS, a citizen `of the United States, residing at (lanisteo,in

the county of Steuben and State of New York,

have invented certain new and useful I mprove-` in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, and to the letters and guresof reference marked thereon, which form a part of this speciication Figure llbeing a side elevation of the pump; Fig. 2, a central vertical section of the body of the pump; Figs. 3, 4, and 5, views of partsV detached.

My invention consists in the combination of an elevating-pipe, formed of gas-pipe, an airchamber and leverstandard,also formed of gas-pipe, and in line with the elevating-pipe, and a spout formed'on the coupling between the said pipes; also, in a pump constructed with gas-pipe Ieverstandard and air-chamber and elevating-pipe, arranged in a straight line, anupper water-way connected centrally with the elevatingpipea lower water-way sepa-` rately formed and removable, valve-boxes secured in the lower water-way, pump-barrelssecured between the two waterways,`pistons, and piston-rods hung to the handlelever,which is mounted on the lever-standard, all substantially as hereinafter set forth.

Referring to the drawings, the main elevating-pipe A extends upward to a proper posi,- tion to attach the discharge-spout B, which is secured to a pipe-coupling, a, on the upper end of the pipe A. This spout `B may have a pipe, C, attached for forcing the water to a greaterheight than the spout. To the coupling a another piece of pipe, D, is4 secured in line with themain` pipe A, to form the airchamber and the supporting-standard for the pump lever or handle E,`which is pivoted to a suitable cap, b, screwed or otherwise fitted air-tight upon the upper end of the standard.

The above construction of the elevating pipe, standard, and air-chamber requires the piston-rod of the pump to be outside thereof;

part of Letters'latent No. 273,985, dated March 13, 1883. Appncatioii inea .my 14,1882. (No model.)

and I prefer to employ two pistonrods,G` G,

with pistons working in two pump-barrels, H`

H, to make a double-acting pump, as shown in the drawings, by which, with a little additional expense over a single-acting pump, a continuous stream of water is raised, and more water is raised with the same power and in the same vtime than with a single-acting pump.

The main elevating-pipe A is secured on, supported by, and connected with the interior water-passages from the two pump-barrels in the upper water way or cap, I, of the pumpbody. Each piston-rod Gr passes through a packing-box that is composed of the shell or box proper, L, screwed down into a hollow seat, c, on the cap I, and of a perforated nut, M, through which the piston-rod passes, Vscrewed down into the boxL to compress the packing. This method of constructing the packing-box is strong, compact, and does awayv with projecting iianges and bolts.

.The piston-valve N is formed as -a simple disk with two perfectly plane surfaces, so that either side maybe used to fit on the valve` seat, 'and-when one side fails to fit its seat tightly it can be turned the other side down.

It is held so as to play freely in its cage.

Each lower or check valve, P, ot' the pump is constructed with a plane face to tit the valve-seat, and a central stem on top to play in a guide. Its seat Q is a box cast separately, as shown in Figm, with a plane surface, d, to t tightly against the upper interior surface ot' the lower water-box, l, of the pump-body, and having ilanges ff, by which to bolt or screw it to its attaching part. A

guide-yoke, g, is secured to the seat'on the inside, in which the stem of the valve plays.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a pump, the combination of the elevating-pipe'A, formed of gas-pipe, the air-chamber and lever-standard D, also formed of gaspipe, and in line with the elevating-pipe, and

I ermee.;

vatting-pipe A, arranged in a straight line, the 1ever-standard,all substantially as and for the upper Water-Way, I, connected centrally with purpose herein specified. 1o the elevating-pipe, the lower Water-way, R, In testimony whereof I affix my signature in separately formed, and removable valve-boxes presence of two Witnesses.
