IMPROVEMENT IN PUMPS.

The Schedule referred to-in these Letters Patent and making peri: of the same.

To all whom it mag/concern Be it known that I, JACOB SCOTT, of Earlville, county of Delaware, State of Iowa, have invented a new and improved Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l

y Figure 1 is a. central vertical section, partly in elevation, of my improved pump, showing the position of the parts.

Figure 2 is afront elevation, showing how the exterior poltions of the pump are held in position.

Corresponding letters refer to corresponding parts in each of the figures.

This invention relates to pumps for elevating water ont of wells, or other reservoirs, andjits 'object is to provide a pump less expensive in its construction, the parts of which are more simple, and easily constructed by persons not supplied with ull sets of tools for pump-making, than are the pumps now in use; and to this end,

The invention consists inthe construction and arrangement of the parts of which it is composed, as will be more fully described hereinafter.

A, in the drawings, is a closed box, of any required size, to be placed in or near the bottom of the well,

or other reservoir containing the water to be raised. This box is to be provided with a series of apertures upon its sides for the admission of water to the in'terior thereof.

B represents a short cylinder, which is to be firmly secured to the upper surface of box A. This cylinder may be of any desired shape upon its outer surface, it being intended to use wood generally in its construction. It may, however, be of metal, or of any other material, it being provided with an aperture through its centre, within which the piston is to work. This aperture is to be placed directly over a corresponding aperture in the top of box A, so that adirect communication may be' formed between the two.

C represents a valve, which is to be placed at the junction of the cylinder B with the box A, and so arranged that its seat shall be upon the box A, it opening upward into the aperture in cylinder B. l

1B represents another and a shorter cylinder or tube, which is arranged vertically by the side of cylinder B, with which it communicates'through an aperture formed in the side of the latter, at a point, say, three inches from its bottom or lower end.

Cf represents a valve, which is hinged to, and has its seat upon the cylinder B, it being so arranged as to cover the aperture in its side which. forms the communication. The office of this valve is to prevent the water, after it has been forced out ot cylinder B, bythe downward motion of the piston, from returning thereto, as said piston is raised to allow the' said cylinder to be reiilled withwater.

D represents the aperture above alluded to, which forms the communication between the cylinders B and B.

E represents a piston, which fits-the bore-of thel cylinder B, and may be of any length desired.

El represents a rod, which is to be secured to the piston lil, and extend upward above the top ofthe cylinder for a distance suiicient to enable it to be attached to the operating-handle.

E2 represents the handle by which the piston of the pump is operated, its outer end being attached to4 a bracket, or standard, G, which is secured to the upper end of the cylinder B, as shown in iig. l in the drawings, or it may be attached t-o a standard at the top of the well, said standard being constructed independently of the cylinder B. To this handle the rod E1 is attached, at a point directly over the aperture in cylinder B, so that as its outer or free end is moved up and down, water willvbe forced out of the said cylinder by the piston E, upon its downward stroke, the vacuum formed therein by its. upward stroke, whichwill permit the water to dow in through valve G, and refill the saine, so that the operation may be repeated.

F represents the discharge pipe of the pump, which is to be attached to the upper end of cylinder B', as shown in tig. 1, it leading from that point to the top of the well, and from thence to any point to which it may be desired to conduct the water.

At any point above the platform, covering the well or reservoir in which the water is contained, this discharge-pipe may be provided with a cap, having upon it the necessary screw for attaching a hose, which will cause the pump, when-operated briskly, to perform the function oi' a hre-engine or a tire-extinguisher,

and thus a safeguard against the destruction ot' buildi ings from that cause may always be at hand.

H H represent bolts, which are to be secured to the top of box A in any suitable manner, and extend up and through a cap of iron or other material, to be placed over the top of cylinder B.

Upon the outer upper ends of these bolts, nuts are to be placed, which wili bear upon .the cap I, and, as they are turned down, will press upon the cylinder B and box A, and thus unite the parts-together, and prevent any leakage at the joints, they havingbeen provided with suitable packing forthat purpose.

Some of the advantages due to this form of constructionI may be stated as follows:

First, it is more simple, consequently less expensive than any other pump with which I am acquainted.

Second, it is easily and quickly convertible into an El, lever Ez, :md fulcrum AGr, all as shown and deengine for extinguishing fires, which is regarded as scribed.

:L very important feature. Signed at Earlville,1owa, this 16th day of October,

Hzwing thus described my invention, A. D. 1869.

What I claim, and desire to secure by Letters Pat,- `JACOB SCOTT. y ent of the United States, is-

A pump, consisting of the perforated chamber A, Witnesses: the pump-stock B, eduction-pipe B', hinged valves C 'CUMMINGS SANBORN, and G', eduction-passage D, solid piston E, pisto1i=rod J oHN B. HEALY.
