PUM P-VALVE.

SPECIFICATION forming part of Letters Patent No. 231,522, dated August 24, 1880.

Application filed March 12, 1880. (No model.)

To all whom fit may concern:

Be it known that I, HENRY R. BARBER, a citizen of the United States, residing at Lambertville, in the count-y of Union and State of New Jersey, have invented new and useful Improvements in Pump-Valves, of which the following is a specification.

This invention relates to valves for the barrels of ordinary lift-pumps, and has for its obi o ject to simplify the construction of such valves, to render them more effective in operation, and to impart to them durable qualities not possessed by such valves as heretofore constructed.

The invention consists, essentially, in a pum-p-valve made wholly of rubber and in a single piece, composed of a ring and a valve arranged within and disconnected from the same, except at a single point, which serves as 2o a connecting-joint by which the valve can vibrate, the upper surface of said valve being formed with an enlargement or prot-uberance serving as a weight to close the valve when raised by the action of the pump-piston.

The invention further consists in a pumpvalve made wholly o1' rubber and in a single piece, composed of a ring, a valve arranged within and disconnected from the same, except at a single point, which serves as a con- 3o meeting-joint by which the valve can vibrate,

an enlargement or protuberance on the upper side of the valve, serving as a weight to close the valve when raised, and an arm or lever projecting in an upwardly-inclined direction from the protuberance or enlargement, which serves as a means to temporarily retain the valve raised from its seat, the several parts before mentioned being molded or shaped integral of rubber, whereby a cheap, durable,

4o and efficient pump-valve is provided, and one in which the weighted protuberance and its arm or lever cannotbecome detached from the valve proper, which is very liable to occur where such weight is made of metal and connected to the valve by' a screw.

In the accompanying drawings, Figure l represents .a view of my improved valve applied to an ordinary pump, Fig. 2, a perspective view of my improved valve.

5o Referring to the drawings illustrating one mode of using my valve, the letter A indicates an ordinary pump-barrel provided with the usual valve-seat a, and B indicates a pumppiston, all of which may be of any known construction. y

The improved valve is composed wholly of rubber and in a single piece, and is preferably molded into shape, but it may be otherwise brought into the required form.

It consists of an annulus or ring, O. and a 6o disk-valve, D, arranged within the ring, and disconnected therefrom by an intervening annular space, b, except at a single point, where said valve is joined to the inner portion of the ring by a connecting-piece or narrow strip, c, which serves as ajoint by which the valve can freely vibrate.

The Lipper side or face of the disk-valve is fashioned or formed into asemi-cylindrical protuberance or enlargement, E, from which ema- 7o nates a teat, arm, or lever, F, which is located at one side of the vertical axis of the semicylindrical enlargement, and which extends in an upwardly and outwardly inclined position, so that it may be struck by the piston when desired, for a purpose hereinafter explained. The" valve thus formed is arranged over the end of the pump-barrel, the ring O resting on the ledge c and the disk-valve D resting on the valve-scat a of the pump-barrel. The ring 8o O is confined in place on the ledge of the barrel by a metallic annulus, d, suitably confined m place, all in such manner that no water can escape between the outer edge of the rin g and the pump-cylinder.

Although I have illustrated this manner of applying my valve to a pump-barrel, it is manifest that other means can be employed, as such lform no essential feature of the invention.

The pump-piston is of any of the usual con- 9o structions, being provided with a suitable ball or other form of valve which will open on the descent of the piston and close on the ascen tof the same, the movement of the disk-valve D being of course the reverse of such movement 95 of the piston-valve.

In case it is desirable to permit any water in the pump-cylinder above the disk-valve to repass into the pump-barrel below such diskvalve, in order to avoid freezing of the water 10Q in the pump-cylimler, it is only' necessary to force the piston down to cause it to come into contact with the arm or lever F, which has I the ci'ect of tilting` or lifting the disk-valve l and temporarily retaining '1t in such position until the water in the pump cylinder repasses I into the pump-barrel below the valve, a-tter. which thc pistou is slightly raised to release I the valve, when thc latter will by gravityclose onto its seat. f

The essential and important feature of' my l invention consists in constructing the disk valve, the ring and its connecting-joint, and i the protuberancc or enlargement on the side of the valve, which acts as a weight to alitomatically close the valve, Iall oi' rubber and in a single piece, the whole being fashioned, 1nolded,or otherwise brought into such shape from a. single piece of rubber or from a plastic composition of rubber.

Heretot'ore a pump-valve has been composed of a ring and an interior disk-valve disconl nected from the ring, exceptat a single point, which forms the joint on which the valve vibrates; but in such the weight for closing the valve or the arm for raising the valve by the action ot' the piston has been made of a separate piece, which is connected to the i'ace of the interior disk of the valve by means ot' a Screw passing up through the latter. Such is objectionable, because the screw will tear out it' the parts are made of leather or rubber; but aside from this I am not aware that the intci rior disk-valve has been formed with a molded upwardly-prQiectiug enlargement acting as a l weight to close the valve and formed with a teat, arm, or lever, as in myinvention, whereby I am enabled to produce a pump-valve of this class in a much cheaper manner than those above mentioned, and the parts cannot bedetached.

Having fully described my invention, what I claim is- 1. As an improved article otl manufacture, a pump-valve formed oi' a ring and an interior disk-valvejoincd to the ring atasingle point, and having formedintegral with the disk-valve a molded upwardly-projecting enlargement, serving as a weight to automatically close the disk-valve, said parts being formed from indiarubber, all in a single piece, substantially as set i'orth.

2. A plunpvalve consisting of a ring and a disk-valve arranged within and disconnected from the same, except at a single point, which serves as ajoint, said valve heilig' formed with a protuberance or enlargement on its side,

serving as a weight, from which cmanatcs all upwardly and outwardlyinclined arm or lever, the said parts being formed wholly otl rubber and in a single piece, substantially as shown and described.

In testimony whereot'I have hereunto set my hand in the presence of' two subscribing witnesses.

H. R. BARBER.
