IMPROVEMENT IN PUMPS.
Specication forming part of Letters Patent No. 48,165, dated June 13, 1865.
description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a vertical section ot' my inven- .tion. Fig. 2 is a plan or top view of the lower half', 0of the skeleton piston head or plunger. Fig. 3 is a plan of the valve D detached. Fig. 4 shows another construction of valve D.
'Lilie letters represent like parts in all the ligures.
This invention relates to that class of 'wellpumps called submerged or hollow-piston 7 pumps; and it consists in apeculiarly-constructed plunger, and in pivoting the bridge ot' the two check-valves to ears projecting from the under side of the valve-plate, which avoids the objection heretofore existing in this class of pumps caused by the opening or communication from one chamber to the other made' for the valve-bridge.
To enable others to work my invention, I will describe its construction and operation.
I use the ordinary cylinder A,havinga side chamber, J, and having lugs (not shown in the drawings) projecting each way at E, by which it is bolted to the ordinary supporting timber or plank.
The plate F,on which the seats of thecheckvalveso and c are formed, has two ears, e, cast to the under side, between and to which the bent lever G is loosely pivoted. Thevalves 'v and o are rigidly attached to the said lever G, and consequently when either is open the other must be closed, and vice versa. I use a hollow piston, P, as shown in Fig. l.
The head or plunger is composed of two parts, B and C, each having a set of valve openings or ports, c and c. The upper half, B, is fitted into O, as seen in the drawings, so as to leave sufficient space between the valve seats ot' each to receive the valve D and afford it proper movement. The ports in B and C are made to register by notching the inner rim of B to receive the top of the guide t'. The wings w of the valve are also notched to lit the guides t' and i. B and C are clamped together by two bolts through the openings 7L. Fig. 2. The object ot such an adjustment of the parts is that the wings w., Fig. 3, of the valve-plate D shall always cover the seats of B and O alternately.
The valve D may be made as shownin Fig. 4, which is simply an annular disk-valve. In this case the exact registry of the ports is not essential, for the valve would cover the seats of the upper or lower portsjust as well. The clamping bolts fitting loosely through the holes b would be a suflicient guide.
It will be seen that when the piston P de scends the check-valve o is'closed and c opened, and the valve D forced up, so as to close the upper ports ot' the plunger. This drives the water from below the plunger in the cylinder A up through the piston, and at. the
same time the upper portion is being tilled.
When the piston ascends the check-valves are reversed and the valve D closes the lower ports of the plunger and opens the upper ones, so that the water from the upper portion of the cylinder is forced out through the piston, thus producing a perpetual discharge.
The valves and valve-seats in this plump are all metal, and there is no packing, except between the cylinder A and the plate It is a perfect anti-freezing pump, for the water mustalways settle to the level of the water in the well when the action of the pump ceases, because one or the other of the check-valves 'U and e is always open.
What I claim as my invention, and desire to secure by Letters Patent, is
The combination and relative arrangement ot' the valves o and n', when rigidly attached to the pivoted lever G, with the hollow piston P, having a head composed of the plates B and O, between which is arranged the diskvalve D, which is constructed and operates conjointly with the other parts, in the manner shown, and for the purposes described.
