To all whom it may concern:

Be it known that we, EDWIN CHAMBERLIN and ANDREW M. GARDNER, citizens of the United States, residing at Avella, in the county of Washington and State of Pennsylvania, have invented certain new and useful improvements in Liquid-Elevating Apparatus, of which the following is a specilication.

rlihe prime object of our invention is to provide a simple, efficient, and automatically operable elevating apparatus.

ln the accompanying drawings, which illustrate an application of my invention,

.Figure -1 is a central vertical sectional view of an apparatus constructed in accordance with our invention; F ig. 2 is a detail central vertical sectional view of the air intake valve mechanism and a portion of the actuating means therefor; Fig. 3 is a horizontal sectional view taken on line lll- 111 of F ig. 2 looking in the direction of the arrows; Fig. 4C is a detailed elevational view of a portion of the inlet valve actuating mechanism and adjusting means for controlling the movement of the valve actuating mechanism; Fig. 5 is a central vertical sectional view of the air exhaust valve mechanism employed; and Fig. 6 is a part sectional view of the air exhaust valve mechanism, the section being taken on line ifi-V1- of Fig. 5.

Referring to the drawings, 1 designates a tank adapted to be submerged or partly submerged in the water to be elevated7 and, as illustrated and as preferred, is provided with

water inlet valves

2 and 3.

l designates a water discharge pipe leading from the bottom of the tank and 5 a spring controlled valve controlling the flow of water through pipe 4.

@ur apparatus is particularly designed for raising or removing water from mines., .although it may, of course, be used for raising water or other liquids wherever desired.

|The apparatus is designed for use in connection with compressed air, and 6 designates a pipe leading from an air compressor, located at any suitable point, to an air inlet valve mechanism comprising, as illustrated and as preferred, a casing 7 having an interior seat 8 adapted to receive a ball valve 9.

`Casing 7 is formed with ak central bore or opening 10 designed to receive a stem 11. rIhis valve stem 11 passes through a plug cap 12, the latter closing the lower end of the casing.

13 designates a guide for the stem 11, and located between the lower end of the said guide 13 and the upper end of the plugI 12, we provide a compression spring lil, the function of spring 14 being to maintain the stem 11 up into engagement with the ball 9 after it has been moved upwardly by the air inlet valve actuating mechanism, hereinafter described. Located on the opposite side of the tank from the inlet valve mechanism, we provide an air exhaust mechanism, said latter' mechanism being connected by a pipe 15 to the inlet valve to enable the compressed air to be passed from the inlet to the exhaust valve mechanism.

The exhaust valve mechanism, as illustrated, comprises a casing 16 having a horizontally disposed outlet chamber 17 and a nozzle 18, the latter being adapted to be extended through a side of the tank and be connected with an exhaust air outlet pipe 19. The lower end of the casing 16 is closed by a cap 20, the latter having a contracted nozzle 21 adapted to be connected with a coupling member 22, said coupling member 22 in turn being connected with the pipe 15. Coupling member 22 is provided with a reducing nozzle 23 through which the compressed air is discharged into the interior of the tank.

Located within the interior of the casing 16, we provide a spring controlled plunger 24, said plunger 24 being provided with a stem 25 adapted, as the plunger 24 is raised, to pass through a guide 26, and, interposed between said guide 26 and the plunger, we provide a spring 27. The casing 16 is provided with a series of ports 28 designed, when the plunger er piston 24E is in its lowered position, to permit the passage of air from the interior of the tank to the air outlet nozzle 18. l/Vhen the plunger is raised by the compressed air, said air ports 28 are. closed, thereby cutting off the escape of air from the interior of the tank.

The air inlet valve mechanism is actuated by means of a float controlled mechanism comprising a float 29, a pivoted rod 30 having its inner end pivotally secured to a block 31, said block 31 being provided with a threaded stem 32 adapted to project through a wall of the tank and be secured thereto by means of anut 33. The rod 30 is connected with the valvestem 11 by adjustable mechanism comprising member 34, the latter having bifurcated

end portions

35 and 36, the ends 35 being formed with openings to receive a pin 37 passed through the rod 30 and the said arms 35. Interposed between the upper spaced ends 36 of member 34 and the stem 11, we provide a block or link 38.

This block or link 38 is connected with the arms 36 by a pin `39, the latter being adapted to rest upon an adjusting screw 40 disposed in the lower end of the block 38, and adapted to coperate with a threaded opening 41 of the'block and into which the screw 40 is entered. The upper end of the block or link '38 is provided with a threaded opening adapted to receive the threaded lower end 42of'the valve stem 1l.

,43 designates an adjusting nut arranged to'coper'ate with the threaded portion 42 of valve stem 11. and bear upon the upper face of 1 the block 38. By means of the adjusting mechanism connecting the valve stem 11 and the rod 30, we are enabled to cut oif the Vsupply of air at any desired position of the' float, and thus regulate to a` nicety the quantity of compressed air necessary to effectively operate the apparatus.

Assuming that the water or other liquid has entered the tank to a predetermined level, the air inlet valve 9 is raised from its seat by the valve actuating mechanism, thus permitting compressed air to be passed from the air inlet valve casing 7 to the pipe 15 and from pipe 15to the exhaust valve mech- Thecompressed air raises the plunger' 24,v thereby closing the ports 28 and preventing the escape of air from the interior of the tank. Simultaneously with the moving of plunger 24, the compressed air discharges through the contracted nozzle 23 expanding and forcing the liquid contents oftheV tank out through the discharge pipe. Thel descent of the ball float draws the valve operating stemv 11 downwardly out of contact' with the ball valve 9, thereby permitting said valve 9 to drop upon its seat and cut off the supply of air to the tank.

After the air has been cut olf, as above described, the expansion' of the air within the tank will force all the liquid in the tank out through the discharge pipe. After the liquid .has been discharged, the pressure within the tank is reduced sufficiently to enable the spring 27 to move the plunger 24 downwardly past the ports 28, thereby enabling the contained air to pass from the interiorof the tank outwardly to the atmosphere through Vthe outlet nozzle 18. By this arrangement, it will be noted that we are enabled to "save a considerable quantity of air,"for it will be noted that the air introduced prior to cutting olf the supply of air will expand and operate as above described.

What we claim is:

1. In a liquid elevating apparatus, the combination with a tank, of automatically operable air inlet and exhaust valve mechanisms, a pipe for air leading from the inlet to the exhaust valve mechanism, said exhaust valve mechanism including a plunger adapted to be operated by the air from the inlet valve mechanism, means for actuating the inlet valve mechanism including a float and adjustable means intermediate the float andthe inlet valve mechanism, a liquid intake valve within the tank, and a liquid discharge pipe.
