UNITED STATES PATENT OFFICE.
FORCE-PUMP.
SPECIFICATION forming part of Letters Patent No. 362,263, dated May 3, 1887. Application filed Auigilst y16, 1886. Serial No. 211,092. (No model.)
Ton/,ZZ whom# may concern.'
E@ it known thai, THOMAS o. niwonrr, a
citizen ot the United States, residing at St. Clairsville, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Force-Pumps; and I do declare the following to be a full, clear, and exact description of the invention,'such as will enable otliersskilled in the art to which it apvpertains to make and use the same, reference being had to the accompanying drawings, and to .the letters and figures ot' reference marked thereon, which form a tion.
This invention relates to pumps; and it consists in the novel features, more fully hereinafter set forth and claimed.
In the drawings, Figure 1 is a side elevation, and Fig. 21 is a vertical central longitudinal section.
The device comprises the tubular parts A and C. The part Gis smaller in diameter than the part A and telescopes therein. The upper end is provided with `a packing confined between two annular shoulders or rings, formin a piston-head, D, which-is adapted to fit within the part A. The lower end has a series of perforations through its sides, through which the uid passes when the end is resting upon the bottom of the Vessel. A valve, I, of ordinary construction, is located within the part C, preferably near the lower end; but this is immaterial. By having it near the lower end repairing is facilitated, as it can be readily reached. A stop, G, consisting of an annular shoulder, is located at a distance from the head D, and is designed to strike against a stop or shoulder, b, within the part A, preferably formed by bending the lower edge inward. By having the stop G thus arranged at a distance from the head and snugly fitting the inits movements without any binding. It is further guided by the shoulder or stop Z, which fits close against it, as shown.
The part A may be of any desired length and composed of one or more sections, two being preferred, united bya coupler or sleeve, b. The sections A and B are preferably of the same diameter. The upper section, A, is provided with a valve,E, near its lower end,
part of this specica,
anda coilspring, F, interposed between the valve-seat and the head of the plunger C, n or mally holds the same at its lowest position relative to the part A, which is when the stop G rests upon the stop b. The upper end ofthe section A is closed by a knob, H, which forms an air-chamber, lc, between it and the valve. A tube or pipe, J located within this lchamber, has its lower end terminate a short d1s tance from the valve and its upper end extended through the side of thesection, ]ust below the end of the knob H, to receive the end of the hose K.
By having the part A made in two sections,
'and the valve E located near the end of the upper section and the spring F seated within the upper end of the lower section, access may be readily had to each for repairing .or cleaning.
In practice, after the device is primed, which may be accomplished by filling it with water from either end, or holding the lower end in the water and alternately pressing upon and removing the pressure from oft' the knob, a continuous stream can be thrown by continuing the operation just described. When the knob is pressed upon, the lower valve, I, 1s closed, the upper valve opened, and the part A moved over the lower part, C. During this operation the capacity between the two valves is reduced and the excess of fluid forced above the valve E into the chamber lc, compressing the air therein, which reacting forces the iiuld through the pipe J. As the part A is pressed down the spring F is compressed, and when the pressure is removed the part A rises by reason of the reaction of the spring. At and during this movement the upper valve closes and the lower valve opens and a fresh supply is taken in. The air is sufficiently compressed in the chamber la by the previous downstroke that during the upward movement of the part A a continuous discharge takes place.
The pump may be used simply for lifting, if so desired, without departing from the nature of my invention.
Having thus described my invention, what I claim, and desire to secure, is-
The herein shown and described force-pump, consisting ofthe following elements: the upper and lower telescoping parts, the upper part comprising two sections, A and A', the coupler b', uniting them, the valve E, located near IOO the inner end of the section A', the plug` lil, the valve E andthe end oi' the lower part, the
closing its outer end, the tube J, located within annular stop G, to limit the outward movenlent the space between the plug and valve and of the part C, and the valve I, located within having its lower end extended close to the the lower end of the lower part.
