SPECIFICATION forming part of Letters Patent No. 601,920, dated April 5, 1898.

Application filed June l, 1897.' Serial No. 638,848. (No model.) I

To all whom it may concern.-

Be it known that I, MILO LUTHER GATES WHEELER, of North Yakima, in the county of Yakima and State of Washington, have invented certain new and useful Improve- :ments 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 improvements in lifting-pumps, and has reference to that class of pumps whereby a column of water is raised or directed to any desired point by the action of compressed air or steam-pressure.

The invention consists in the novel features of construction hereinafter more particularly set forth and claimed.

In the accompanying'drawings, forming a part of this specification, Figure 1 is an elevation. Fig. 2 is a top plan view. Fig. 3 is a vertical sectional view of Fig. 1. Fig. 4. is a sectional detail View of the barrel-casing of i the valve for controlling the admission of air to the tanks. Fig. 5 is detailview of the Valve. Fig. 6 is a sectional detail view of the valve-casing and valve controlling the admission of air to the cylinders. Fig. 7 is a detail view of the valve and operating-arm, and Fig. 8 is a detail View of the arm for operating said valve.

Referring to the drawings, A is a casing which is divided by a transverse partition into the two compartments or tanks A A said casing being supported upon suitable skids 1.

Each compartment or tank isprovided with a dome Q,having-the tops or covers g, through which extends a tube M, which terminates a short distance from the bottom of each tank,

said tube servingas a guide for the vertically-moving rods M, having on their lower ends the plates P. Freely movable upon each tubular guide M is a float L, whose movement is effected by the rise and fall of the Water within the tank.

I is a pipe leading from an air-compressor (not here shown) and united at its lower end to the five-way coupling J, which constitutes the valve-casing for the valve K, which is movable therein. Pipes I and I communicate with the respective tanks A and A at their lower ends and at their upper ends unite with the five-way coupling at the points d d. The two remaining openings of the five-way coupling e 6 receive the exhaustpipes f, which may be connected with a receiver upon the surface and to the air-compressor, the same not being here shown, so as to form a complete circuit, and thus the air exhausts under a full pressure and gradually decreases to the atmospheric pressure which will serve to assist the power driving the aircompressor, thus effecting a saving in said power.

S S indicate two cylinders which are connected together by the casting s, which constitutes one member of the clamp by which the cylinders are secured to pipe P, a yoke s encircling the pipe and being united to the casting by securing-bolts. Movable within these cylinders are the pistons T, which are connected together by the piston-rod T, so that they move in unison.

2 are vertical pipes which communicate at their lower ends with cylinders S S adjacent their outer ends and 'at their upper ends engage one of the openings of the three-way couplings t t, while horizontal pipes or; m are also united to the three-way couplings and at their upper ends communicate with pipe 1 Intermediately pivoted to the coupling which unites the pipes at as to the pipe 1 is the lever 0, having the rods N N pivoted at their upper ends to its opposite ends and at their lower ends secured to the coupling sleeves y, through which the upper ends of rods M extend, and are secured by set-screws M The three-way couplings t and 15 form valve-casings for valves V and V, which are concave, as illustrated, and which are provided with concave depressions which are adapted to register with pipes 2 and m or m or with pipes 2 and the exhaust-openings 3 in the three-way couplings. The stem of each valve projects through the coupling and has secured thereto the operating-arm W, carrying at its outer end the pin W, which is adapted to engage the slot 0 in the end of said lever. It will be noticed that these arms extend in opposite directions from each other and that as lever O is operated the valves V and V alternately open and-close communication between the pipes 2 and a; 0c.

Springs u are positioned upon the valve-stems on the opposite side of the couplings between the ad justin g-nuts and the outer walls of the couplings, so that the valves are held firmly at all times to their seats.

The main valve K is provided with a central passage a b and has its opposite sides provided with the concaved depressions c 0. Secured at one end to the valve K is the arm 9', which is slotted at its upper end to receive the pin 7", carried by the piston-rod T, so that the movement of the pistons will operate said valve to cause it to establish communication alternately between the pipes I and I and I and I and also with the respective exhausts c. This valve is also provided with the spring a for the purpose of holding it firmly to its seat.

H H are outlet-pipes which communicate with the respective tanks A A and have secured thereto the valve-casings G G, in which are located the valves F F. Secured at one end to the valve-casing G is the delivery-pipe E, while secured to the valve-casing Gis the delivery-pipe E, said pipe communicating with pipe E: I

O C are the water-inlet pipes, provided with the inclined valve-seats C C and the valves D D.

4 4 are vertical pipes which communicate at their lower ends with domes Q Q and at their upper ends with the horizontal pipe 5, which communicates with pipe E. The pipe 5 is provided with a stop-cock 6, while pipes 4 are provided with the valves 7.

As illustrated in Fig. 3, communication is closed between the compressed-air supply and pipe I,while communication is established between the same and pipe I, thus conveying the air to tank A. The pressure of the air upon the water forces the latter upward through the outlet-pipe and delivery-pipe E. As the water lowers in the tank, float L follows the same downward, and when the latter comes in engagement with the plate P its weight will move the rods M N downward, causing that end of the lever O to which they are secured to be depressed, raising its opposite end. This movement of the lever through the medium of the short arm W moves the valve V, so that it closes communication between the pipes 2 and w and permits the air in the cylinder S to exhaust through ports 3. At the same time valve V is moved to establish .communication between the pipes 2 and 0c and close the exhaust, so that air is admitted in the cylinderS and moves the piston T toward the opposite cylinder, which, through the medium of the connection between said piston T and the arm 7", moves valve K to close communication between the pipes I and I and establish it between the latter and pipe I, so that air is admitted to tank A which has filled with water during the emptying of tank A. It will be understood that the movement of the lever 0 also moves rods M and N and returns plate P to its normal position.

By having a connection between the domes of the tanksand pipe E a portion of the air may be admitted to the discharge-column of water, thereby lightening the water column proportionately to the volume of air admitted, and thus raising the water to a much greater height with a given air-pressure from the aircompressor than obtained by forcing a solid column of water in the pipe. This construction is especially desirable in discharging the water from deep mines, although for this character of work the pump may be operated in relays and greater lifting force may be obtained for each pump, and therefore requiring a small number of relay-pumps.

My pump may be operated by any power suitable to operate an air-compressor and is adapted for use as a deep-mining pump as well as for hydraulic mining, and it is adapted to receive water from any supply, conveying it directly to the desired point without the necessity of building expensive ditches or troughs, only to be abandoned when the claim is worked out. This pump is also adapted for irrigation and may be operated by a windmill power, as will be understood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
