` IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 59,364, dated November 6, 1866.

To all whom it may concern.'

Be it known that we, ALBERT GONANT and IsRAEL F. BROWN, of N ew London, State of Connecticut, have invented a new and useful Improvement in Pumps, and we do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to thc accompanying drawings, forming part of the specification, in which- Figure 1 shows a peripherical view of so much of the cylinder Or barrel of a pump and of its valve as it is necessary to show in order to explain my improvement. Figure 2 is an axial section.

This improvement ink pumps is intended to simplify the construction both Of the barrel or cylinder and its valve, at the same time improving the working of the valve, making it accessible and easy to be cleared from obstructions, and also rendering its removal easy of accomplishment without the use of tools, since `it needs only be lifted out of the cylinder, there being no fastenings to hold it ou its seat.

The letter A designates the lower part of the cylinder or barrel of a pump. The upper part (not here shown) is continued upward to the height which it is desired to give to the pump.

It has been common hitherto to form the lower part of a pump-cylinder- Of two or more separate and distinct parts or pieces, bolted together or otherwise secured, one or more of such pieces being required to form the valveseat of the induction-valve placed in the bottom of the pump.

Sometimes one or more of such separate parts or pieces have been formed into a valvebox, which is next secured in the lower lpart of the cylinder Or barrel.

One of the features of our invention is making the cylinder or barrel Of a pump in such a way that the bottom thereof,` including the valve-seat, shall be a solid component part thereof, being cast or made whole in one piece. Any desirable form may be given to the cylinder. In this example l have cast the bottom of the cylinder with a neck extending downward, said neck being of less diameter than the l ,cylinder, and forming, in conjunction with its sides, a shoulder, I, which serves as the seat of the pump-valve.

Upon the exterior of the cylinder, at its bottom, is cast with it a circular ange, H, on

which the pump is supported, and which serves to connect it to any structureor platform over a well or reservoir. Y

D is the valve. lt is placed loosely on its seat. Its form is that of an inverted cone, its base being made flaring so as to bring it near the val ve-seat, and its sides being tluted so as to furnish a large water-way around the valve between its sides and the edge of the valveseat. The tapering stem G Of the valve is extended downward below the bottom line or end of the neck F, being made of a length sufficient to prevent the valve from being lifted wholly above the valve-seat by a full the valve and allow the pump to be emptied of its contents when forced down low enough for that purpose.

It will be Observed that this pump is complete, so far as its bottom and valve-seat and supporting-flan ge are concerned, when it comes from the foundery, without requiring fitting and adjusting and fastening together as in ordinary pumps, and, furthermore, that the valve can be dropped to its place and removed without the use of tools, as in the case of those valves which are secured by screws or other fastenin gs.

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

l. The wings J of the single taper stem G in combination with the loose valve B, arranged and operating in the manner and for the purpose herein specified.

2. The tilting-arm E in combination with the cap G, of the loose valve B, arranged and Operating in the manner and'for the purpose herein specified.
