PUMP.

SPECIFICATION forming part of Letters Patent No. 255,966, dated April 4, 1882,

Application filed November 19, 1881.

To all whom it may concern.-

Beitknown thatI, MOSES G-AYMAN, ot Canal Winchester, in the county of Franklin and State of Ohio, have invented a new and useful Improvement in Pumps, ot which the following is a i'ull, clear, `and exact description.

Reference is to be had to the accompanying drawings, forminga part ot' this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my improved pump. Fig. 2 is a side elevation of the plunger or bucket, and Fig. 3 is a plan view ofthe same.

The invention consists in certain combinations which will be described in connection with the drawings, and then pointed out in the claims.

This pump is adapted to be used in either open wells, driven wells, or cisterns, or at any place where a pump is wanted, and to be used for extinguishing tires, sprinkling streets, 85e., and it is not to be hung upon the curb or platform of the well, as is the case with ordinary force and lift pumps, but is adapted to be snpported at or from the bottom ot' the well.

The water-chamber A may be made of iron or of wood. Ifmade of wood, the side openings, d d', will be faced with the iianged and internally-threaded metal thimbles c o', and the central opening,f, will be faced with the eX- ternally-threaded annular metal cup or collar g, which is provided with the annular screwcap h, which, together with the cup g, forms the stuffing-box e, which surrounds and makes a tight joint with the valve-rod D, or with the sleeve E, as the case may be.

In the thimble a is screwed the air-chamber B, and in the thimble a is screwed the discharge-tube F. In case the chamberA is made of iron, of course the side openings will be in. tcrnallythreaded to receive and hold the airchamber and the eduction or discharge pipe, and the thimbles a and a will be dispensed with.

In the opening j in the under side of the chamber A, which registers with the opening j', is secured, preferably by means of the braces (No model.)

c c, the large induction-pipe L, in which the valve or bucket J, secured upon the lower end ofthe rod D, moves. To the lower end ofthe pipe or cylinder L is secured the bottom pipe, G, which may be wood or iron. When it is wood it carries at its upper end the tlapvalve K, and when it is iron the ap-valveis secured in the bottom ot' the cylinder L. The lower end ot' the pipcG rests on the bottom of the well at i t' and 'supports the whole pump. The valve or bucket J has secured upon its upper end the leather sleeve a, which projects above the solid portion ofthe valve or bucket, as shown in Fig. 1.

VVthin the space surrounded by the leather sleeve, above the solid portion of the valve or bucket, is placed upon the rod D the circular leather flap or disk p, which is held upon the upper end ofthe solid portion of the bucket by the nut s, and serves to close in the ordinary way the passages t t through the solid portion of the bucket. By this means the flap is protected from contact with the walls of the pipe L, and the edge ot' it coming against the inner wall of the leather sleeve when closed makes a tightjoint therewith and prevents all backward ow of water.

In case the pump is to be made double-acting, I place upon the rod D the inverted elongated cup or sleeve E, which moves with the said rod and serves to diminish the space in the water-chamber and cylinder upon the downstroke of the rod, and thus forces the water therefrom through the discharge or eduction pipe. This inverted cup or sleeve is adjustable vertically upon the rod by means of the screw-thread of the rod,as will be clearly understood from the drawings.

The spout H is made reversible, or so that it can be turned to either side ot' the pipe F to suit the position of the pump-handle I. This is accomplished by means ot' the threeway joint K, which is internally screwthreaded at all ofits openings, as shown, and receives the upperend of the pipe F, 'the horizontal spout H, and the fulcrum-post N ofthe lever. Thisjoint may be turned so as to hold the spout in any direction from the pipe F desired.

The pipe F is provided with the perforation or winter-leak 7c. Below the perforation or leak is riveted the spring l, which closes over the perforation while water is being forced through the pipe F, but which automatically springs back to the position shown in the dra-wings when pumping ceases, and thus opens the leak and permits the water in the pipe to escape.

In case the pump is not to be made doubleacting, the inverted cup or sleeve E will not be used, and, as above intimated,the stufling-box e will be made to tit the rod D, or the rod may be made to tit so closely in the openingf that a stufng-box will not be needed.

The induction-pipe L, instead ot' being held by the rods or braces c c, may be screwed into the water-chamber.

The water chamber A and induction pipe or cylinder L may be made as one casting or frame,

with an opening or passage upward through the water-cham ber sufficiently large to admit the valve or bucket J, and thispassage to have openings at eilhrr side to admit the water to the openings d df, and the top of this passage to be closed by means ofa metal plate having in it the stuffing-box e.

I am aware that it is not new to use an airchamber screwed in the upper end of stock or cannected rigidly with the plunger, or to make van air-chamber in the form of an inverted cup on the end of piston-rod; but

What I claim as new is- 1. The combination, with the externally endthreaded pipes F Hand fulcrum-post N,of the three-way joint K, internally screw-threaded at each of its openings, as and for the purpose specified.

2. The combination, with the dischargepipe F, having waste-hole 7e', of the platespring fastened at bottom, arranged to cover thehole when the pump is in operation and to spring away from the hole as soon as thepump ceases to work, as shown and described.
