PUMP.

Application filed May 5, 1916.

To all whom t may concern:

Be it known that I, DAVID G. WHIiRRY, a citizen of the United States, residing in Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in P umps, of which the following is a specification. i

This invention has reference to an organr zation of movable elements which are capa ble, under the pressure of a fluid medium, of furnishing power, and which are capable, onthe application of power thereto, of moving or lifting a fluid medium, as in the pumping of water, or of pumping air for the purpose of compression or for the various uses for which the compressed air-,may be employed. The objects of the invention are, to ac complish the movement of a fluid medium of largest possible volume, combined .with continuity of impulse and least expenditure of mechanical energy, and to provide mechanism with movable elements that'may be driven in either direction for pumping purs poses.

Other objects and advantages may appear from the subjoined detail description.

In the drawings-Figure 1 is an elevational section with receding parts in perspective, of a pump incorporating the principles of this invention. F1g..2 is a side elevation of the pump. Fig. 3 is a perspective detail of a rotary abutment. Fig. 4 is a side elevation of the primary rotor. Fig. 5 is an elevation of the inner side of the casing, and shows one of the slide `valves which controls the admission ofwater to the piston chamber. Fig. 6 is a side elevation of the fluid medium distributing plate, showing the four slide valves, the rotor being shown back of the plate in dotted lines. Fig. 7 is a plan section on the line X7 of Fig. 2. i

Referring to the drawing, the rotative and 'operative elements referred to are mounted in a suitable casing 1, having the outer end walls 2, 3, which are provided with intake and exhaust ports or openings 4L, 5, respectively, connecting with intake and exhaust chests, 10, 11, respectively. The shaft 6 is journaled in the end walls 2, 3, and has mounted thereon the rotor 7 and the pulley 8. When used as a pump, the pulley 8 is the driving member, and the rotor 7, the driven member. The rotor 7 1s Specification of Letters Patent.

provided with a series of radial vanes 9 which serve as force and suction elements. Slide valves 13, 14, 15, 16, are provided with studs 17, projecting into groove 12, in end wall 27, of the rotor; said studs being' provided with rollers 18, working in slots 20, in plate 19, and actuating the valves to open and close ports 2l, 22, 28, 2st.

A series of intermittently rotating abutmeiits 25, are provided and divide the space between the outer wall 26, of the rotor and the wall of the casing l, into `a sei-ies of contiguously-arranged chambers, each of said chambers having theintake port at one corner, and the exhaust port at the diagonally opposite corner.

Assuming the device to be used as a pump, the water enters the intake chest l0,

and from thence is drawn through the ports 21, 22, 23, 24t, through the suction created by the vacuum made by the vanes 9 as they pass the intake ports and recede from the abutments 25. The water thus drawn in by one of said vanes is forced out and into the exhaust chest l1, by the next successive vane. The water thus has a practically continuous movement through the device. Three vanes are shown but any number of vanes may be used, and the force or velocity of water projected by one vane will be blended with the impulse that is created by the next successive vane. In installing the device for use, the exhaust pipe (not shown) may be provided with a check valve (not shown) to prevent any back pressure of the water.

Abutments 25, which divide the annular space within the casinginto a series of compartments, have an intermittent rotary motion to allow the vanes 9 to travel from one compartment to another. Each slide valve is in closed position while the vane is passing the corresponding intermittent rotary abutment.

From the foregoing it may be seen that theinvention comprehends an organization of movable elements, operable through independent paths, but each element interde pendent upon the other for its movement, and the combination of which is capable of pumping water or air, or producing power. Certain of the elements are interdependent upon the others for the regulation of the power of the medium by which the others are operated. The intermittent rotary elements are supported'by the `pressure of the power producing medium thereupon, whereby the resistance upon the rotor is reduced to a minimum. The impact sustaining elements upon the rotor vary in number with the impact chambers, whereby the initial force from one chamber will be counterbalanced by the failing force in the others.

The primary object oi the invention is to provide a simple and efficient mechanism for pumping purposes, capable of moving or handling a large volume of water, or compressing or driving a maximum quantity or air, with a minimum expenditure of mechanical power, and capable, as a motor, of

translating fluid medium pressure into me chanical energy.

lVhile the elements shownand described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to vthe precise construction shown, but minor changes `and modiiications which may fall within the scope of the appended claims, may be made.

What is claimed is:

1. A pump casing having an intake chest, an exhaust chest, an intermediate piston chamber, a rotary piston in the intermediate chamber, spaced apart from the casing wall, intermittently lactuated rotary abutments dividing the inclosed space into compartments, andoscillating slide-valves actuated by thepiston-to open andclose communication between the piston chamber and intakel and exhaust chests.

2. lA `pump comprising acasing, a rotor within the casing, the rotor being spaced apart from the wall of the casing, rotary abutments dividing the space between the periphery of the rotor and the wall of the casing intoa series of contiguous compartn ments, intake and exhaust chestsadjoiningV the rotor chamber, ports of communication between said intake and exhaust chests and said compartments, whereby the transition of water is effected, and valve means V`for opening and closing said ports.

3. In a pump, the combination with a casing having chambers and ports leading from one to another of said chambers, of a rotor in one chambenoscillating members in another of said chambers toopen and close Said ports, and means to actuate the oscillating members to open and closed positions.

4. In a` pump, the, combination with a rotorhaving a grooved end wall, of a casing for the rotor, slide valve members in continual contact with the grooved end wall, vanes on the rotor, and intermittent `rotary abutments forming compartments within the casing and adjacent to the rotor, said slide valve members having an intermittent oscillating' `motion to admit fluid or air medium within the compartments.V

5. In a pump, the combination with a series of ixed fulcrum angularly movable valve members, of a rotary piston for effecting the movement of said valve members.

6. In a pump, the combination with a rotary piston and a casing having ports therein, of aseries of pivoted slide valves having an angularA movementl in unison with the movement or' the piston toy control said ports. y 4' 7. In a pump,the.combination'with acasing, of a rotary piston withinpthe casing, the

periphery or the piston' being spaced apart from the wall of the casing to AJform an fannular chamber, suction and force vanes extending radially rom the kperiphery ofthe piston, intermittently,'actuated `rotary abutments dividing the lannular chamber into' a series of contiguous compartments, varying in number from the piston varies, said compartments having inlet and discharge ports, and means actuated bythemovement ofthe piston to open and close said ports..v
