11 Claims.

The present invention relates to pumps and more specifically to pump operating means.

One of the objects of the invention is to provide power driven pump operating means which is adapted to be applied to existing hand operated `lift pumps to enable the delivery oi the water under pressure.

Another object is to provide operating means including a pressure pump adapted to operate in series with the hand operated lift pump.

Another object is a pump mechanism which, while permanently installed adjacent the lift pump, may be quickly disconnected so that the lift pump may be hand operated, and may be just as easily and quickly connected again for power operation.

Other| objects and advantages will be apparent to those skilled in the art upon reference to the followingdescription and the accompanying drawings in which Fig. l is a side elevation of the power operated pump mechanism in operative relation to the Dump- Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary side elevation illustrating the pump mechanism arranged for hand operation.

In the drawings a conventional hand operated lift pump is shown at III, this being provided with the usual pump cylinder and water pipe extending down in the well and not shown.

The pump plunger is as usual operated by the rod Il extending down through the pump body and reciprocable by means of the handle I2, this being a lever fulcrumed at I3A on the link I3 and adaptedvtofbe connected to rod II, or an extension lla thereof, by the usual clevis and a removable pin insertable through a hole I4 therein and also through a hole in the extension Ila. I The rod II is as usual guided in a suitable upright I-2A.

Erected adjacent the pump I is a frame consisting of uprights 2li-20A, and an upper cross member 2l supported thereon; and, on the frame, preferably on the cross member 2| is supported an electric motor 22 carrying a small pulley 23, which through belt 24 is adapted to drive a large pulley 25.

The latter, pulley 25, is carried on one end of a short shaft, extending across frame member 2l in suitable bearings, on the other end of which is ilxed a small pinion 26 meshing with a large pinion 21 also mounted on member 2 I.

The pinion 21 is provided with a suitable ec- (c1. 10s-5v) centrically located pin 28 adapted to coact with a pitman 29 extending down to a suitable pivotal connection 29a with a lever 3D, which is pivoted to frame. upright 20A at 3 I the pivot means being a short-link so as to allow a small longitudinal movement of the lever in its reciprocaton by pitman 29. The other end of lever 30 will be pivoted, as by a pin.32,.to the extension lla of the pump plunger rod Il from which the handle l2 is preferably detached. The same hole or opening in extension IIa may be used for the pin 32 which connects either the handle I2 or the lever 3U.

Operation of the motor 22 will, of course, reciprocate the pump plunger and thereby lift water from the well in which the pump is installed. In order, however, to deliver such Water under sumcient pressure, a second pump 40 is used and the plunger 4I of this is also connected pivotally, as at 42, to the lever 30, so that the two pumps I0 and 40 are actuated simultaneously by themotor 22. Y

An easily detachable flexible conduit 43 extends from the delivery spout IDA of pump l0 to the intake valve 44 yof pump 40, and from the outlet valve 45 of the latter a suitable conduit leads to a pressure storage tank 46, fromwhich the water may, of course, be piped to the point or points of use. y v

The capacity of the pump 40 should be such as to accommodate the delivery from pump I0, and by arranging the two pump plungers as indicated, the weight `of the plunger in pump I0 assists the pumping action of pump 40.

If, for any reason, the motor 22 becomes inoperative, the pump 4Il) may be quickly put into use for manual operation merely by removing pin 32 to disconnect the lever 30 from extension Ila and connecting the pump handle I2 to extension Ila by means of pin 32 in the manner shown in Fig. 3. At the same time the conduit 43 is disconnected from the pump.

Further, itis obvious `that pump 40 may, if desired, be set in a suitable pit below the frost line and that the tank 46' may be located wherever is desirable and convenient.
