DOMI'NEK G. STANEK, OF EKALAKA, MONTANA.

PUMP.

Specification of Letters Patent. Patented Dec, 10, 1918,

Application filed January 27, 191?, Serial No. 144,876.

To all whom it may concern:

Be it known that 1'. DOMINEK G. STANEK, a citizen of the United States, residing at Ekalaka, in the county of Fallon and State of Montana, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pumps, and the primary object of the invention is to provide a pump structure, whereby water will be forced upwardly from the bottom of a well, by means of pressure generated by a falling weight or piston.

An object of this invention is to provide a pump structure as specified, which includes a casing inserted in the well within which a piston travels in a vertical manner and to attach a Windlass to the piston for ralslng or lowering the same and further to connect a water pipe to the bottom of the well, so that when the weight or piston is lowered in the well, the water will be forced upwardly out through said'pipe.

A further object of this invention is to provide means for permitting air to enter the well beneath the piston or cylinder.

\Vith the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters designate like and corresponding parts throughout the several views, and in Which:

Figure 1 is a vertical section through a well and pump constructed in accordance with this invention.

Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary section of a modiground beneath the bottom of the well as clearly shown at a in Fig. l of the drawings. The casing 3 is provided with an opening 5 formed therein at the bottom of the well, through which an elbow 6 extends. The pipe elbow 6 is connected to a vertical water outlet pipe 7 which extends upwardly through the platform 2, and has its delivery end 3 curved downwardly as clearly shown in the drawing in Fig. 1.

A piston 9 is slidably' mounted within the cylindrical casing 3.- The piston 9 is composed of a plurality of sections 9 and 9 which are mounted upon a pipe 11. The pipe 11 eXtends centrally through the sections 9' and 9 of the piston and it has its lower end screw threaded as shown at 9*, for connection with the lowermost of the sections 9 of the piston 9. A collar or nut 10 is threaded upon the pipe 11 and engages the upper surface of the uppermost sections 9' for clamping the various sections 9 and 9 of the piston upon the tank and in firm engagement with each other. The sections 9 of the piston are smaller in diameter than the sections 9 and they have leather washers 1.0 about their circumferences and extending across their upper surfaces, which washers are adapted for engagement with the inner wall of the shell or cylinder 3 for forming an air and fluid tight engagement between the piston and the inner surface of the well casing 3. The pipe 11 has anenlarged head 12 formed upon its upper ends, to which a chain or analogous flexible member 13 is connected. The chain 13 is in turn connected to the roller or drum 1% of a Windlass structure. The drum 1% is mounted upon a shaft 15 upon which a gear 16 is mounted. The gear 16 meshes with a gear 17 mounted upon a shaft 18. The shaft 18 has a crank handle 19 formed thereon for facilitating the manual'rotation thereof. Suitable standards 20 are provided for supporting the shafts 15 and 18.

A flap valve 21 is carried by the undersurface of the piston or weight 9, and it is provided for permitting air to pass downwardly through the pipe 11 into the space beneath the piston or weight, when the latter is being raised and for preventing the escape of air through the pipe when the piston or weight is being lowered.

When it is desired to pump water from the well 1, the roller 1 1 is rotated through the medium of the handle 19, shafts 15 and 18 and gears 16 and 17 for unwinding the chain or flexible member therefrom, which allows the weight or piston 9 to fall by its own weight. The falling or downward movement of the piston or weight 9 will force the air downwardly, compressing the same beneath the piston, which will exert a downward pressure on the water, causin the same to flow through the elbow 6, pipe and out through the outlet 8. The piston 9 is raised by the winding rotation of the drum 1%.

The cylindrical casing or shell 3 has the usual type drill shoe 3 removably connected to its lower end, as clearly shown in Fig. 1 of the drawings.

In F 3 of the drawings, a slight modification of the invention is shown, wherein the cylindrical shell or casing 3 is provided with a transversely extending opening 3 in which a collar or washer 3 is removably mounted. The collar or washer 3 has valve seat 3 formed therein and an ordinary check valve 3 positioned therein for allowing water to flow into the casing, but preventing it from flowing out of the casing. The modified form illustrated in Fig. 3 is provided for use in wells where a vein of water communicates with the side of the casing, and a check valve 3 is provided for preventing the weight or piston 9 from forcing the water out through the opening 3 upon its lowering into the well.

From the foregoing description taken in connection with the accompanying drawing, the advantages of construction and of the method of operation of the improved pump will be readily apparent to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction combination and arrangement of parts may be altered to suit practical conditions pro vided such alterations are comprehended within the scope of what is claimed.

What is claimed is:

1. A well pump comprising a cylindrical casing adapted to be arranged in a well; an outlet pipe in communication with the lower portion of the well and extending upwardly therefrom; a piston arranged within the cylindrical casing and adapted for vertical movement therein, said piston being composed of a plurality of superposed sections one of the sections thereof being smaller in diameter than the other section; leather washers encircling the smaller sections of the piston and forming a fluid pipe joint with the casing; means to raise and lower the piston; a pipe passing vertically through the pistonand extending upwardly therefrom; a collar arranged on the pipe for clamping the sections of the piston together; a check valve disposed at the lower end of the vertical pipe to control the passage of air and water therethrough.

2. A well pump comprising a cylindrical casing adapted to be arranged in a well; an outlet pipe in communication with the lower portion of the well and extending upwardly therefrom; a piston arranged within the cylindrical casing and adapted for vertical movement therein, leather washers arranged on the periphery of the piston and in c011- tact with the casing for forming a fluid tight joint, a pipe passing vertically through the piston and extending upwardly therefrom, means secured. to the upper end of the pipe to raise and lower the piston, a check valve disposed at the lower end of the vertical pipe to control the passage of air and water there through.

3. A well pump comprising a cylindrical casing adapted to be arranged in a well; an

outlet pipe in communication with the lower portion of the well and extending upwardly therefrom; a piston arranged within the cylindrical casing and adapted for vertical movement therein, said piston being composed of a plurality of superposed sections; leather washers encircling certain of the sections to form a fluid pipe joint with the casing; a pipe passing vertically through the piston and extending upwardly therefrom; a collar arranged on the pipe for clamping the sections of the piston together, means to raise and lower the piston; a check valve disposed at the lower end of the vertical pipe to control the passage of air and water therethrough.

In testimony whereof I afiix my signature in presence of two witnesses.
