Letters Patent No. 89,023, dateel April 20, 1869.

IMPROVEMENT IN PUMP-VALVES.

The Schedule referred to in these Letters Patent and making part of the sama.

To all whom 'it may concern Be it known that we, HENRY O. BULKLEY and AMos SHEPARD, of New Britain, in the county of Hartford,

and State of Connecticut, have invented a new and useful Improvement in Pumps; aud we do hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being hadto the accompanying drawings, making a part of this specification, in which Figures 1, 2, 3, and 4, are transverse vertical sections ofdiferent styles of our invention, all of which are substantially the same.

Figure 5 is a plan or top view of the base of a pump, as tted, ready for the application of our invention.

Figure 6 is a plan. or top View of the valve-seat.

Figure 7 is a plan or top view of the valve.

Figure 8 is a plan view of one end of the cylinder.A

Similar letters of reference indicate like parts.

Our invention consists in arranging the cylindervalveseat and valve in such manner that one portion of the end of the cylinder shall come indirect contact with the valve-seat, and another portion with the valve, thus forming both an elastic and a solid metallic joint.

Our invention lis intended particularly to be applied to pumps which are fastened by screwing the cylinder into the base, and the drawings of cylinder and base,

figs. 5 and 8, represent Asher Burrs improved pump.

connection, patented May'l, 1866, to which it is applicable, but it can be applied to most of the suction-pumps now in use.

On the end of the cylinder B we make an annular rccess, a, the inside diameter of which is equal, or more, than the diameter of the valve C.

The depth of the recess c, or the distance from the valve-seat D to the nearest point inthe bottom of the recess c, should be a little less than the thickness of the valve .0.

A pump made, with our improvement' applied to it, is put together in the following manner:

The valve C is placed in ithe recess a, when the cylinder B is secured to the base A`. As the cylinder B is brought to its place, it first engages the valve C, penetrating or compressing it until it is stopped by contact with the valve-seat D. The cylinder' B will penetrate or compress the valve C, according to-its thickness.

Figs. 1, 2, 3, and 4, show different forms of our invention, but allare-for the same object, and accomplish the same result in a similar manner.

If the valve-seat D is of the proper thickness, the end of the cylinder B, asit is screwed orturned iuto'the base A, will come in contact with it, and effectually prevent the cylinder from being turned further than is required, thu's leaving the cylinder and base in their relative positions, the spout and brake lon the cylinder being in their proper positions. n

In the ordinary pumps, the end of the cylinder rests on the valve() alone. As the cylinder is screwed or turned down, the valve C is' compressed between the valveseat D and end of cylinder. If the valves are of different thicknesses, the relative position of cylinder and base will vary accordingly.

By use, the valves are worn, and the action of the water softens them, consequently the cylinder becomes loose, and it is found necessary to screw or turn down the cylinder to. tighten it. In this manner the relative positions of cylinder and base are changed,.and the spout and brake thrown from their proper positions.

By our invention, we produce a pump in which the cylinder B and base A will always bear the Same relative position, whatever may be the thickness of the valve O, thus compensating and accommodating it to valves of'diti'ereut thicknesses.

When one valve is worn out, it can be replaced by another, without changing the position of handle and spout.

We also produce a superior joint between the valveseat and cylinder.

What we claim as new, and' desire to secure by Letters Patent, is

A pump-valve, C, and valve-seat D, secured in their places, by means ofthe end of the cylinderB, resting on and in direct contact with both the valve C and valve-seat D, all as and for the purpose substantially as required.
