COMPRESSED-AIR PUMP.

SPECIFICATION forming part of Letters Patent No. 631,732, dated August 22, 1899.

Application filed October 5 1898. Serial No. 692,700. (No model.)

lTo all whom. it 1v1/ty concern,.-

Be it known that I, THOMAS C. WRIsTEN, a citizen of the United States, residing at Dighton, in the county of Lane and State of Kansas, have invented certain new and useful Improvements in CompressedAir Pumps;

and I do declare the following to be a full,

. der side, made of cork or other light material,

. and faced with-rubber or leather. casing 13 is similar to the casing 11 and is joined to the top of the reservoir 18 in like ,mannen 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.

My invention relates to an improved form of forcing-pump for raising water by the action of compressed air; and the object of the invention is to provide a simple, effective, and reliable device for this purpose.

To this end the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully explained, and particularly pointed outin the claim.

In the accompanying drawings, Figure 1 is a vertical section of my improved pump. Fig. 2 is a detail View of' the rod 14 with its connections.

The same figures and letters refer to the same parts throughout the views.

1 denotes the well, and 2 the cover or platform, on which the air= pump barrel 3 is mounted.

18 represents a reservoir, which consists of a closed chamber, cylindrical or polygonal in form, located below the water-line in the well and provided with a removable top c, a waterinlet valve 17, (any number of which may be used,) an escape-pipe 22, and a discharge-pipe 20, which latter extends from near the bottom of the reservoir 18 upward through the platform 2 and terminates in the usual gooseneck 21 and is connected bya pipe 6 with the lower end of the pump-barrel 3.

An air-chamber may be used in connection with the reservoir 18 and may be placed either within or without the reservoir; but it is not essential to the successful working of the pump, and it forms no part of my present invention.

A downwardlyopening foot-valve 5 is mounted in the upper end of the pipe 6, and the lower end of the pipe 6 is closed by the spring-valve 7. The valve-casing 11 may be of any convenient form, open for the free passage of air and water. It is reduced at the upper end, as shown in the drawings, thread ed, and screws into a threaded orifice in the top of the reservoir 18. Through its lower end passes the set-screw 10, which, operating against the disk 9, adjusts the tension of the spring 8.

12 is an air-outlet valve, conical on the un- The valve- 15 is a metallic disk, to which is attached a cork e or other light substance having a cavity in its lower face,'as shown in Fig.y 2, and it has a vertical movement in the cylindrical casing 16, which is open for the passage of air and water and is iixed to the bottom of' the reservoir 1S in any suitable manner. The disk 15 is buoyant and always remains at the top of the casing 16, except when the surface of the water in the reservoir 18 falls below that point.

14 is a rod threaded at each end. Its lower end screws into a threaded orifice in the disk 15, while its upper end passes up through an orice in the valve 12 and is then reduced, as shown, at the point a, Fig. 2. A Washer Z), Fig. 2, which prevents the escape of air along the rod 14 through the valve 12, fits over this reduced part, and a nut d, Fig. 2, screws down to hold the washer b and the valve 12 in place. The washer ZJ and the nut d are secured in place after the top of the reservoir 18 has been placed in position and before the pipe 22 has been attached. The valve 12 is free to move upon the rod 14 the full length of the casing 13, and the rod 14 is of just such a length as will permit the valve 12 to close only when the disk 15 is pressed against the top of the casing 16, the valve 12 pressing alike against the top of the casing 13 and the washer b, Fig. 2.

19 is a check-valve in the discharge-pipe 20, and 22 is a pipe through which air escapes from the reservoir 18. It is connected with the reservoir 18 and terminates at some point above the water-line 23 in the well.

As the piston 4, which may be operated by hand or power, descends a charge of air is forced into the air-pipe 6. The valve 5 prevents its return. When the air in the pipe 6 IOO is sufciently compressed to open the springvalve 7, which is adjusted to open only when the pressure is sufficient to force water out through pipe 20 and gooseneek 21, it passes into the reservoir 18. As the Water enters the reservoir through the valve 17 it rises and closes the valve 12. Each additional stroke of the piston 4 forces a corresponding quantity of water from the reservoir 18 until the water receding from the iioat e, to which the disk 15 is attached, the disk and valve 12 then fall of their own Weight. opens, allowing the Water to ow infroin the Well. The disk 15 rises with the Water to the top of the casing 16. The Water continues to rise in the reservoir 1S and on reaching the valve 12, the same being buoyant, carries -it up t0 the pipe 22, thus closing it against the further escape of air. The pressure of the compressed air coming through valve 7 keeps it opened until the reservoir 1S is again emptied to be refilled as before.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, l do not.

desire to be confined to the saine, as such `changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention,

The valve 17 said disk'and spring to close said valve 7, thev easing 16, the disk 15, and the float e mounted therein, the casing 13, the valve 12i1nounlted therein, the rod 14 connecting said valve 12 and disk 15, and ythe.airpipe 22 extend-ing from a point above the Water-level, terminating in the reservoir, .and inthe path of the valve v12, substantially as shown 'and described.

In testimony whereof I have `.hereunto sct my hand in presence of two subscribing witnesses.

. THOMAS C. VRISTEN.
