Application filed January 25, 1917.

To all whom it may, concern:

Be it known that l, EDWIN E, THOMAS, a

citizen of the United titates, residing in the "ty of Portland, county of Multnoinah, and smite of @i'egon, have invented certain new and useful Improvements in Pneumatic veer-Lifting Devices, of which the following is a specification.

My invention relates to pneumatic water lifting; devices of that class adapted to be placed in well, or submerged in a body of wate and adapted to be operated by means of pressed air, controlled by a float, for the purpose of forcing water from said well. or body of water to a higher elevation.

oi? the principal objects of my invention is to provide simple, practical and omatic pllllllllllC water lifting device such consti tion that it can be used to Lift vater from any body of water which is H sullicient depth to receive the device, thus it capable of adaptation to any locat n and for any capacity.

(Ether ts and advantages ill be apparent n the following description of one practical embodimentof the invention,

to. on in connection with the accompanying sheet of drawings illustrating the same, and in which,-

Figure 1 is a side elevation of a complete device with the outside shown in ver-' tical section;

2 is an enlarged, sectional view of the upper end of the device;

3 is a side elevation looking at the hand side oi the device, as shown in Jig. 1.; and

Fig. at is a reduced, horizontal, view taken on line M of Fig. 2.

My invention, as here illustrated is particularly adapted for use in wells, and comprises an outer casino 1, adapted to be let down into a well, and provided at its lower end with an inlet check valve 2, for admitting: water to the lower end of said casing and for preventing its escape therefrom. Said casing is provided at its upper end with a top cap 3, upon and through which is mounted the controlling mechanism of device. Mounted through said top cap 3, is a water pipe 4;, provided at its upper end with a check valve 5, the lower end of said wipe terminating a short distance above the inlet check valve 2, in said casing 1. Slidably mounted around said pipe 4, within sectional Specification of Letters Eatent.

Serial No. 144,439.

vided in side with a longitudinally e2;- iendinp; groove, or socket 8, as clearly shown in Fig. Said valve-operating rod 7, is pr vided at its lower end with a knob 9, at its upoer end, within said casing, a cor? ending knob 10, said knobs ptel to be engaged by said float be; e. fl. id operating rod 7, operates through a suitable packing 11, in said top j 3, and is provided at its upper end with nuts 12 and 13, and with two coiled springs l and 15, hearing at their extreme r iposite ends against the nuts 12 and 13,

adjacent ends against washerl6 and 17, between which a ver 18, is connected to '7, as clearly indicated in lever 18, is connected 1 3361 19, turning; within the is, which is supported on the said valve casing being 3, pipe 22, through c 1, and also havan air pipe 23, pressure can be valve casing and the end of the main cascasing also has an eX- .pted to be connected with W when the valve lever 18, is l d downwardly at its outer end, in a n 431 and for a purposeshereinafter again referred to.

The operation of my invention may be briefly described as follows: With the parts in the positions as shown in Figs. 1 and 2, the casing 1, is supposed to be filled with water which has entered said casing through the inlet check valve 52, carrying the float 6, to the top of the casing 1, where it is about to engage the knob 10, on the operating rod 7, in such manner that it will raise said operating rod 7, and thus raise the valve lever 13, and turn the valve member 19, so as to open communication between the air supply pipe and the pipe 22, leading into the top Of the casing 1, above the float 6. This air pressure within said casing above the water will force the Water into. the lower a manner as to move it downwardly, thus moving the valve lever 18 downwardly, and turning the valve member 19, so as to open communication between the pipe 22, and the exhaust outlet 24:, in said valve casing 20, at the, same time cutting oil the air supply through the pipe 23. With the exhaust 24 open, the air in the casing 1, passes out freely as another supply of water runs in through the inlet check valve 2, again raising the valve '6, to the top of the casing 1, where its operation is as before described.

Attention is called to the fact that with the coiled springs 14 and 15, on the valve operating rod 17 above and below the end of the valve lever 18, said valve lever is given a quick movement in either direction, for the springs will be partially compressed by the movement of the float 6, against the knobs 9 and 10, on the operating rod 7, before said valve lever 18 is started. As soon as the tension of either of the springs 14 or 15, as the case may he, becomes sufficient to overcome the friction of the valve lever 18, it will be moved quickly, and thus quickly open full communication between the pipes and 22, or between the pipe 22 and the outlet port 24:.

It will thus be seen that with a supply or air under pressure connected to the pipe 23, my device will operate continuously and automatically to lift the water from the well through the pipe l and the check valve 5, and thence to its place or" delivery. The broken lines in Figs. 2 and 4 indicate a well casing.

I am aware that changes can be made in the details of my invention, here shown for purposes 01'": illustration, without departing from the spirit thereof, and I do not, therefore, limit the invention to these details, except as I may be limited by the hereto appended claims.

1 claim:

1. A pneumatic water lifting device of the character referred to, comprising in combination with a well, a casing having a valve-controlled inlet at its lower end to permit inflow and prevent outflow, a water supply pipe extended down into said casing and opened at its lower end, a float around said pipe within said casing, said float substantially filling the space around said pipe within said casing for the length of said float, a valve-operating rod in said casing and through said float adapted to be moved in opposite directions as said float reaches the opposite limits of its movement within said casing, means for connecting a source of air under pressure with said casing outside of said pipe, a valve with valve lever interposed in said connections for cutting 0E said air supply, said valve having an exhaust port adapted to be put into communication with said casing when the air supply is cut off therefrom, said valve-operating rod operating through said valve lever, and yieldable connections between said valveoperating rod and said valve lever, whereby said valve lever is yieldingly moved in opposite directions by said valve rod and said float, substantially as described.

2. In a water lifting device, in combination, a tubular casing having a valve-rentrolled inlet at its lower end, a discharge pipe extended down into said casing, and open at its lower end, a float moving up and down around said discharge pipe within said tubular casing, a three-way valve controlling the inlet and exhaust from said tubular casing, said valve having an operating lever, an operating rod extending down into said tubular casing and having means at its opposite ends for movement by said float as said float rises and falls in said tubular casing, said rod operating through the EDWVIN E.
