' UNITED STATES PATENT OFFICEO m ISO J. SEHORNE, OF SMITHLAND, TENNESSEE, ASSIGNOR OF ONE-HALF TO JERRED R. TAYLOR, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 375,202, dated December 20, 1887- Application filed April 2, 1887.

To all whom it may concern.-

Be it known that I, Isorr J. SEHORNE, a citizen of the United States, residing at Smithland, in the county of Lincoln and State of Tennessee, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to a double-acting pump constructed in such a manner that, no matter in which direct-ion the handle is moved, the pump will act with equal efticiency, as will be hereinafter described. To this end I employ a suitable chamber or casing,within which is centrally situated a disk suitably pivoted to the side walls of the casing, the periphery of said disk being sufficiently distant from the inner surface of the chamber or casing to form channels or ways of suitable size for the passage of the fluid. Communicating with openings in the bottom of this chamber are two pipes or conduits, which may be of any desired length, and situated within these pipes are pistons or buckets, each connected by means of a rod to an arm projecting from the periphery of the aforesaid disk. The openings in the bottom of the casing are provided with suitable valves so constructed as to prevent the escape of water through said openings, and at the same time permit the passage of the rods which connect the respective pistons, with slotted arms projecting from diametriccally-opposite sides of the disk aforesaid, to which latter the required oscillatory motion may be imparted by a handle of ordinary construction operating through the medium of a connecting-rod.

The invention consists in certain features of novelty, which are hereinafter particularly pointed out in the claim, being first fully described with reference to the accompanying drawing, which represents my improved apparatus in vertical section, and in which- A represents a chamber or case, within which is situated a disk, B centrally pivoted at 1?, the said disk being provided with slotted arms R, projecting from its periphery at diametrically opposite points. Iivoted to these arms are the piston-rods L, which extend downward through openings in the bottom of the casing and into the pipes or con- .Serial No. 236,444. (No model.)

duits G, where they have secured to their lower extremities pistons or plunger-buckets T, of suitable construction to operate under the conditions shown.

In order that the valves V, which cover the openings in the bottom of the tank, may work properly, it is necessary that the rods should maintain at all times astrictly vertical position, and for this reason the arms R are slotted, and the rods are provided with suitable means for engagement, whereby they may move toward and from the periphery of the disk as they rise and fall. Each of the valves is formed in two parts, hinged at opposite sides of the opening which it is employed to control, and meeting over the center of said opening, their meeting edges being cut away forthe accommodation of the piston rod.

An operating-handle is shown at H, which is pivoted to the pump-barrel in the usual manner and jointed at its inner end to the downward'extending rod W, said rod being attached to one of the arms R or connected in any other suitable manner to the disk. It is shown in the drawing as formed in continuation of the piston-rod L.

It will be seen that channel-ways N exist between the periphery of the disk and the inner faces of the chamber to allow the passage of water.

S is the punipbarrel, which communicates with an opening in the top of the casing.

As the rod \V, which extends through the barrel S, moves up or down, the operation will impart to the disk a reciprocating or oscillatory motion upon its pivots, which, aet ing through the medium of the arms R, will cause a vertical reciprocation of the pistonrods L.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the shell or casing having openings for the ingress, and egress of fluid, a pair ofpipes, each communicating with one of the pair of ingress-openings"and extending downward, a disk pivoted within said casing and having slotted arms projecting from its periphery at diametrically-opposite IOO points, a piston in each of said pipes, pistonthe center of said opening, said meetingedges rods, each connected at one end to one of said being cut away for the passage of the piston- IO pistons and engaging the slot in one of the rods, substantially as set forth.

arms of the disk, and atwo-part valve for preventing the escape of water through each of ISOM SEHORNE' said pipes, one part of each of said two-part Vitncsses:

valves being hinged at each side of the in- J. RUFUS HANoooK,
