ROTARY PUMP Filed Aug. 2, 1938 M m m mm IN R w T R n flTTORNEX Patented Feb. 6, 1940 UNITED STATES PATENT OFFICE ROTARY PUMP Arthur M. Briggs, Huntington Park, Calif.

Application M18118? 2, 1988, Serial No. 222,825

2 Claims.

This invention relates to a rotary pump, in which the rotor is provided with a plurality of flexible vanes or fingers, the outer edges of which engage the inner surface of the case of the pump as the rotor is rotated.

An object of my invention is to provide a novel rotary pump of the flexible vane type, in which an inclined or cam surface is provided to flex each of the vanes in succession as the rotor is rotated, thereby constructing a chamber to expel fluid through the outlet of the pump.

Another object is to provide a rotary pump of the character stated, which is simple in construction, inexpensive to manufacture, and effective in operation.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing Figure 1 is a transverse sectional view of the pump.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Referring more particularly to the drawing,

the numeral I indicates a pump case or housing, which is provided with an intake 2 and an outlet 3. An inclined or cam surface 4 extends between the intake and outlet of the pump, substantially as shown in Figure 1. The remainder of the inner surface of the case I is substantially cylindrical, and the purpose of the cam surface 4 will be further described.

A rotor 5 is positioned with the housing I, and

is fixedly attached to the upper end of a shaft 6. The shaft 6 is journaled in a sleeve I, which is integrally formed with the housing I of the pump. A packing gland 8 is mounted on the lower end of the sleeve 1, and surrounds the shaft 6 for the purpose of preventing leakage. The shaft 6 is driven from a suitable source of power through any suitable means, such as the pulley 9. The rotor 5 is preferably formed of rubber, or some other suitable yieldable substance, and is provided with a plurality of radial vanes Ill, which are integrally formed with the hub of the rotor. The rib II is formed on the outer end of each of the vanes, and extends longitudinally, the purpose of the rib being to provide a wearing surface of effective contour and 5 which will increase the useful life of the pump.

A cover plate I2 is attached to the top of the housing I and is suitably attached by means of screws or the like. The rotor 5 rotates in the direction of the arrows shown in Figure 1, and 10 as each vane strikes the cam surface 4, it will flex as shown in Figure 1, thus constructing one of the pumping chambers I 3, and thereby ejecting the fluid through the outlet 3. As soon as the vane passes the surface 4, it will straighten 15 to a radial position because of the flexible material of which the rotor is made.

The successive flexing of the various vanes will thus cause fluid to be drawn into the pump and ejected therefrom, as the rotor 5 rotates. 20

Having described my invention, 1 claim:

1. A rotary pump comprising a housing, said housing having spaced inlets and outlets, a cam surface on the inside of said housing, said cam surface extending from the inlet to the outlet, a 25 concentric rotor within the housing, said rotor having a plurality of flexible spaced vanes projecting from the body of the rotor, means to rotate said rotor, each of said vanes being successively flexed as they contact said cam surface 30 during rotation of the rotor, the body of the rotor being spaced from the cam surface.

2. A rotary pump comprising a housing, said housing having spaced inlets and outlets, a

straight cam surface on the inside of said hous- 35 sa'rmm as. names. 5
