SAMUEL PARADIS, OF OTTUMWA, IOWA.

FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 233,012, dated. October 5, 1880.

Application filed January 29, 1880.

To all whom it may concern:

Be it known that I, SAMUEL PARADIS, of Otturnwa, in the county of Wa-pello and State of Iowa, have invented an Improved Double- Acting Force-Pu1np, the following being a full description thereof, reference being made to the accompanying drawings, making apart of this specification, in which- Figure 1 represents a side elevation of a device to which my improvements have been applied. Fig. 2 represents a central vertical section through the pump stock and pumpcylinder, showing the arrangement and operation of my device. Fig. 3 represents across section at center of cylinder, plunger, and plunger-valve.

Letters of like name and kind refer to like parts in each figure.

The design of myinvention is to get an even flow of water upon each upward and downward stroke, of the plunger-rod with the most simple construction possible and at the expenditure of the leastamount of power as to the result attained; and for these purposes my invention consists in a double plungervalve attached directly to the operating-rod, and imparting motion to aplunger-piston having openings at its center to admit water to its interior, and working within a cylinder provided with openings to admit water to its interior.

In Figs. 1 and 2, AA represent a cylinder opening at top and bottom into pump-stock B, the openings being fitted with selfacting valves 0 and D. In the center of cylinder A A are slots or openings E E, designed to admit the free flow of water into cylinder, as hereinafter described.

Within cylinder A A is fitted plunger F F, it being also a cylinder, into which is placed, in a socket, so as to allow an upward-anddownward play of from one-fourth to threefourths of an inch of the plunger-valve G, to which plunger-rod is attached at H. In the center of plunger are also slots or openings 6 0, through which water passes into main cylinder, as hereinafter shown.

Cylinder A A may be made of one piece and connected with pump-stock B by sections I I. Plunger F F is made in sections in order to introduce plunger-valve G, which valve is made solid in one piece, with pin running through center at H, connected with an operating'rod.

Figs. 1 and 2 represent pump submerged in water to point K. The plunger F starting upward, space L being filled with water, valve 1) will be opened by the pressure of water, and the water will pass into punip-stockB and be forced upward through it. While plunger F is moving upward, plungeuvalve G being raised into upper end of its socket, a space is opened at its bottom, as shown at M, through which water will pass through lower end of plunger F into cylinderA, filling space N. \Vhcn plunger F is forced downward plungeuvalve Gr will drop into lower end of socket, closing space M and opening a space at top of plunger-valve Gr, also closing valve 1), and the water in space N will be forced against valve (J, which will be opened, and the water will pass into and be forced upward through pump-stock B, while water passing through space at upper end of plunger-valve G will refill space L, and thus the single cylinder A A, with slots or openings at center, in to which is placed plunger F F, with slots or openings at center and fitted with plunges valve G, connected with pumpstock B, constructed and operated as shown, will cause water to be forced upward through pumpstock upon each upward and downward stroke of the plunger-rot Two pum ps constructed as above shown may be attached upon opposite sides of a single pump-stock and operated by one plunger-rod.

The entire pump may be made of wood or metal, or partially of each.

WVha-t I claim as new is 1. In a doubleactingforcepump, the reciprocating double plunger-valve G, attached directly to the operating-rod, in combination with plunger-piston F, and imparting motion to said plunger, substantially as set forth.

2. In a double-acting force-pump, the cylinder A, having slots E, and plunger-piston F,

provided with two val\-*e-seats, and having slots 0, in combination with the reciprocating double plunger-valve G, attached directly to the operating-rod by arms H, and imparting motion to plunger F, substantially as set forth. Witnesses: SAMUEL PARADIS.
