ANDREW P. DROIT, OF

FRESNO, CALIFORNIA.
ROTARY PUMP.
Application filed May 31,
To allwhom it may concern:
Be it known that I, ANDREW P. DRoN citizen of the United States, and resident of Fresno, in'the county of Fresno and the State of California, have invented a new and useful Improvement in Rotary Pumps, of which the following is a specification.
My invention relates to pumps for raising liquids and which are especially useful in wells having a long lift, one of the objects being to have the pump near or below the water level. In pumping water from wells it is desirable to have the power, whether a motor or engine, adjacent to the pump, which under the present state of the-art requires pits, expensive to construct and areusually unsafe. One object of my invention is to have the motive power used to raise the water adjacent to the pumps without the need of a pit or long shaft. will be hereinafter referred to.
' In the drawing accompanying this specification, Figure 1 is a longitudinal sectional view of the pump whenassembled. Fig. 2 is a cross sectional view along line U-$ in Fig.1. Fig. 3 is a cross sectional View along line g in Fig. 1. Fig. 4 is a cross sectional view along line 22 in Fig. 1. Fig. 5 is a view of the part of the pump which revolves. Fig. 6 is a longitudinal sectional view of the pump showing an air inlet and cup seal, and a discharge opening into the casing. Fig. 7 is a longitudinal sectional View of the pump showing an outlet valve at the bottom. Fig. 8 is an enlarged view of cut seal.
' In said drawings D represents the well which is surrounded by a casing D K is a suction pipe which should extend some distance into the water below the pump, its purpose being to at all times reach below the water level. is the housing for the pumps hereinafter referred to. G is a hollow shaft, hereinafter more definitely referred to. G is a hollow extension of shaft G, the lower end of which rests in a thrust hearing or support 23. Support 23 is braced to housing F by means of braces 22 and 22". II is a combination pump which consists of two centripetal pumps H and H and a centrifugal pump H These pumps have the same outside diameter,.are formed integral, and are attached to hollow shaft G at one end and to extension G at the other. The centrifugal pump is between the centripetal pumps and they are constructed so that the pressure of the liquid discharged by each Other objects lubricating the bearings.

of the pumps is upward. Thus when the shaft Gr 1s being rotated in the direction of the hands of a clock, the arrows 6 indicate that the water from pipe K will be drawn lnto pipe G by centripetal pump H which d1scharges the liquid into the intake opening of centrifugal pump H which will then throw the water from hollow shaft G to a space within the housing F, which feeds the intake of centripetal pump H which then drives the water back into the hollow shaft G from which it empties into a discharge pipe C. 17 replresents the intake for centrlpetal pump and 20 the vanes. 16 is the intake for the centrifugal pump H and 19 the vanes, and 15 is the intake for the centr petal pump H and 18 the vanes. Each of said pumps has a plurality of vanes, but relatlvely the number of vanes in each of said pumps increase from the bottom upward, the object being to have'each of the pumps perform the function of forcing the water at a more rapid flow. In order to do the more effectively the discharge openings of'the three pumps decrease in slze in their order, the smallest of said openings being the discharge into the shaft G.
B is a motor, which is inclosed by a water tight housing E. -Motor B is constructed with the field magnet 3 attached to housing E, and rotor 4.- attached to hollow shaft G. 5 is a conduit for electric Wires 6, 7 and 8 attached to the field magnet 3. 11 and 11 are eye supports attached to the housing E to which rods or cableslO and 12 are attached for the purpose of suspending the combmation pump and motor in a well; 14 is an oil pipe extending from the top of the well to the motor for the purpose of 13 and 13 are non-leaking bearings. 24 is a thrust hearing adapted to hold the weight of the re- VOlVil'lL' parts of the motor and the pump.
In Fig. 7 I have shown a similar device with the difference that the discharge pipe G empties the water into the well above the motor and the housing E is hermetically sealed by means of a pliable cup ring 27 which is attached to the housing on the inside periphery while the outside periphery bears against the inside wall of the well. 27 a is a bracket on the housing for the purpose of supporting the cup ring 27. 28 is an outlet valve which permits air from within the housing E to enter the portion of the well under the motor. In Fig. 6 the valve 28 is substituted by a pipe 29 which conducts air to the well under the cup seal 27. The pipe 29 extends out of the top of the well. 30 is a sloping hood constructed over the motor and within the housing, the object being to turn water which might drip through the housing to the outside edge of the housing where it drips to the bottom and form whence it will be removed through the valve 28 by suction from the well.
I claim as new and ask for Letters Patent:

2. In combination a motor and a rotary pump having a common hollow shaft, :1 discharge opening from the pump into the hollow shaft, and a water tight housing inclosing the motor, substantially as described.
3. In combination, a motor and a centripetal pump having a common hollow shaft, said centripetal pump having its discharge opening into the hollow shaft, a water tight housing inclosing the motor, and means for suspending the motor and pump attached into a well, substantially as described.

6. In a device of the character described the combination of a motor and a rotary pump having a common hollow shaft, the rotary pump having a discharge opening into said hollow shaft, and the hollow shaft being adapted to empty into a discharge pipe, a water tight housing for the motor. and a water tight conduit for electric wires leading to the motor, and. leads for oil leading to the motor, and means for hanging said combination in a well, substantially as described.
