1" 0 all whom it may concern:

1 Be it known that I, CrrAnLns 0. Bosses, a

citizen of. the United States, residing at herein. The frame of such a pump com- Atlantic, county of Norfolk, State of Massachusetts, have invented an Improvement in Power Pumping Units, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing'like parts. This invention relates to a power pumping unit or a self contained structure comprising a pump. and a motor for operating the pump. Such a unit renders the pump capable of beingset up in any desired locality and to be readily operated under power to pump a large volume ofwater.

=The object of the invention is to present a unit of this character which shall be compact, and in which the elements shallbe so arranged as to present a well balanced structure having a low center of gravity.

The object of the invention is further to provide a construction in which a standard form of hand pump may be utilized in the "unit, and in which the construction addedto the pump results in a complete structure of power pumping unit which is well balanced and has a low center of gravity. 1 These and other features of the invention will appear more fully from the accompany- .ing description and drawings, and will be particularly pointed out in the claims.

In the drawings:

Fig. 2 is a right hand end elevation of the construction shown in Fig. 11..

Fig. 3 is a top plan view of the supporting frame forming a part ofthe unit.

The pump employed in this unit may be of any standard construction and its mechanism forms no part of the present invention. A standard form of hand pump is illustrated I monly includes a casing comprising a base. 1

and a top section 2, secured together by bolts 3 passing throughlugs i formed on the two parts of the casing; The pumpingmember may he of any type and is herein shown as of the diaphragm type. The flexible dia phragm 5 is clamped at its periphery between the casing parts 1 and 2. The central portion of the diaphragm is clamped between metal rings 6 and 7 in which is mounted the discharge valve 8. The clamping bolts 9 for these rings extend upward and support a cross head 10. The inlet ofthe pump 11 is provided with a suction valve 12 and the discharge outlet is through a spout 13 atone side of the top casing 2. Such a hand pump is usually operated by a handle engaging the cross head so that when the handle is rocked, water is drawn in from the inlet 11 and pumped up through the diaphragm Valve 8 andout over the spout 13.

In the present invention there is provided a supporting frame 14 shown separately in Fig. 3. This frame is secured in superimposed vertical relation to the pump casing and provides the support for the motor and connections necessary to complete the power pumping unit.

. This supporting frame comprises a bed. plate 15 and preferably a depending hollow base 16. The hollow base enables the frame to fit well down over the pump casing and be secured to the pump casing intermediate its ends as upon the lugs 4-. In the construction illustrated the supporting frame is of generally rectangular shape and the hollow depending base 16 is provided with a bottom flange 17 cut away to fit closely against the exterior surface of the top casing 2 of the pump. This flange rests upon the lugs 4 and may be secured in position by the bolts 3, suitable apertured bosses 18 being provided in the bottom flange for that purpose. In the construction illustrated there are four sets of lugs 4 arranged in substantially diametrically disposed pairs but the supporting frame is connected to but three of these pairs because at the fourth position the frame is cut away as shown at 19 to provide for the with the crank shaft uppermost, thus bringing the center of gravity of the motor as low as possible.

The motor is balanced with respect to the pumping member by a crank shaft 24: and connecting parts. This crank shaft 2% extends transversely of the supporting frame and is mounted in bearing blocks 25 bolted at 26 to the frame.

The motor usually runs at a speed much greater than that at which the pump may be eff ciently operated. Consequently reduction driving connections are provided between the motor and crank shaft 24: and such driving connections are herein shown as a system of gears. These gears are also arranged in balanced relation with respect to the pumping member. In the construction illustrated the shaft 22 of the motor is provided at the rear with a pinion 27 meshing with a gear 28 on an auxiliary shaft 29. A pinion 30 on the shaft 29 in turn meshes with a large gear 31 on a shaft 32 extending transversely of the frame intermediate and parallel to the shaft 22 of the motor and the crank shaft 24 At the front the shaft 32 carries a pinion 33 meshing with a large gear .84 on the front end of the crank shaft 2a. This system of gearing is so arranged that the pinions and gears in the rear sub-- stantially balance the pinion and gear at the front with relation to the vertical axis of the pumping unit.

In order to provide a connection from the pumping unit to the crank shaft 24: and maintain a low center of gravity, this invention makes use of a walking beam construction. Thus'the connecting parts which are comparatively light, enable the motor to be set as low as possible. In such a construction a vertical post 35 is supported in a boss 36 formed at the side of the supporting frame. T o the top of this post is pivoted at 37 a walking beam 38 which extends centrally above the pumping member or axis of the pumping unit to a point above the crank shaft 24;. This walking beam is linked to the crank of the crank shaft 24 by a link I") pivoted atel-O to the walking, beam. The walking beam is also linked to the cross head '10 of the pumping member by a link ll pivoted at .2 to the cross head and at 43 to the walking beam.

It will thusbe seen. that the invention presents a self contained structure which may be readily transported from. place to place and set up at any desired. location and at onceput inoperation upon. the operationof the motor. It will be seen thattheconstructicn is such as to. have a. very low center of; gravity, andthat the various elementsane ,et e

so disposed with respect to the central vertical axis, as to be in substantial balance. Thus the pump will function without the necessity of being held down or secured in place and without danger of being tipped over. The supporting frame while disposed well down on the pump casing, is nevertheless so arranged as to permit the discharge from the usual spout 13 arranged at the top of the pump casing. The entire structure is rigid and compact and of simple and durable construction.

If, for any reason, it is desired to use the pump as a. hand pump the link ll may readily be disconnected from the cross head 10 and the supporting frame disconnected from the lugs -l-.

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

1. A power pumping unit comprising a pump casing, a movable pumping member therein, a supporting frame in superimposed vertical relation to the pump casing, a motor mounted on the frame at one side of the pumping member, a crank shaft mounted on the frame at the opposite side of the pumping member, reduction driving connections from the motor to the crank shaft, a walking beam extending above the motor, centrally above the pumping member and above the crank shaft, pivoted to the frame, linked to the crank shaft and linked to the pumping member whereby the frame and parts supported thereby have a relatively low center of gravity and are substantially balanced with respect to the vertical axis of the pump casing.

2. A power pumping unit comprising the construction defined in claim 1 in which the supporting frame is dctachably secured to the pump casing and the link connection on the walking beam is detachably scoured to the movable pumping member whereby the supporting frame and the parts supported thereby may be attached to and removed from a standard pump.

4. A power pumping unit comprising the construct-ion defined in claim 11 in which the motor is an inverted internal combustion engine whereby the center of gravity of the. motor isbrought close to the supporting frame.-

5. A. power pumping unit comprising the construction defined in claim 3 in which the. depending basev is cut away at one side so as notv to interfere with a high discharge opening in. the pump casing.

6 A power pumping unit comprising the construction defined in claim 1 in which the reduction driving connections comprise a shaft intermediate the motor and crank shaft and parrallel with the latter, a large gear at one end of said shaft driven from the niotor a pinion at the opposite end of CHARLES o. noenne.
