This invention relates to improvements in power attachments for motor vehicles.

My improved power attachment as lllllS- trated is a pump ng attachment and I have illustrated my improvements as particularly designed for-such purpose, although I desire to point out at this fame that my improvements are readily adapted for drlving other devices. 1o The main objects of my invention are:

First, to provide an improved pump attachment for motor. vehicles which may be readil mounted upon the vehicle and is supported so that the strains upon the parts of the vehicle are minimized.

Second, to provide an improved pump attachment for motor vehicles which is ver conveniently manipulated and is highly e ficient.

Third, to provide an improvedpower attachment for motor vehicles in which the parts are so arranged as to secure a direct drive from the motor shaft.

Fourth, to provide an improved power at- Y tachment for motor vehicles which may be readily adjusted to compensate for variations in vehicle structures.

Fifth, to provide an improved power attachment for motor vehicles in which the thrust on the driven shaft is effectively sus-' tained. I

Sixth,- to provide an improved power attachment for motor vehicles in which the parts are so formed and arranged that they may be readily set up or disassembled for convenience in transportation and handling.

Further objects, and objects relatin to structural details, will definitely appear rom the detailed description to follow.

I accomplish the objects of my inventlon by the devices and means described in the following specification. .The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention .is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a ront perspective view of my improvements as embodied for a pumping apparatus mounted upon-the vehicle.

Fig. II is a fragmentary front elevation of .their driv ng clutches 1Il engagement.

Fig. IV is a fragmentary sectional View corresponding to that of Fig. III with the clutch members disengaged.

' Fig. V is a detail section on a line respondin to line 55, of Fig. III.

Fi VI is a detail section on a line correspon ing to line 66 of Fig. III, showing further details of the driving connections. Fi VII is a detail section of the supportmg 77 of Fi VI, the clutch control lever being indicated dotted lines.

Fig. VII is a side elevation of the clutch control lever shown b corresponding to Fig. and by dotted lines in position corresponding to Fig. IV.

In the drawing similar reference characcor- 'ters refer to similar parts throughout the sev- 'eral views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the front cross member of the chassis frame of a motorvehicle and 2 the front spring thereof. The engine body is re resented at 3 and 4 is the driving or crank 5'1 I remove the fan belt pulley with which the machine is normallymequip ed and sublt pull stitute therefore the fan ey 5 which is provided with a forwardly projecting sleevellke hub 6 terminating in a jaw clutch member 7. I also substitute a supporting bracket 8 for the bracket usually provided to support the forward engine hanger 3' and the end of the cranking spindle, the cranking spindle being also removed.

I detachably secure a supporting frame 9 to the bracket 8, the bracket being provided ame on a line corresponding to linefull lines in position aft. In practice with suitable holes to receive attaching screws 10. This frame is provided with a stirruplike extension 12 which receives a foot of the supporting bracket 13.0f the pump 14, the pump illustrated being a centrifugal pump. The structural details of the pump are not shown as they form no part of this invention.

The driven-member or pumpshaft 15 is arranged through a cross-piece 16 on the frame, the cross-piece being provided with a bearing 17. At the inner side of this hearing the shaft 15 is provided with a thrust collar 18 so that the thrust on the shaft is sustained by .the supporting frame, and this is of particular advantage in a centrifugal pump where there is usually considerable end thrust on the impeller shaft. By this arrangement of parts I avoid the necessity of providing means for sustaining the end thrust within the pump itself.

It is intended that the bracket'S shall remain upon the vehicle, the supporting frame 9 being removed as desired, although I have found that it is entirely practical to leave the pump mounted in operative position for transportation. This is especially desirable where the pump is used in construction work or for fire purposes and many other uses.

The bracket 8 is attached by means of U- bolts 19 embracing the frame cross-pieces 1.

To reduce the twisting strain'upon this crosspiece and the U-bolts I provide the plate 8 with a thrust screw 20see Figs. III and IV, the screw being positioned on the plate to engage the side of the cross piece, a lock nut being provided for securing the screw in adjusted position. This I find in practice to be a feature of substantial merit.

The driven member or shaft 15 is aligned with the crank shaft 4 as is also the coupling shaft 21 interposed between the crank shaft and the driven shaft. The rear end of the coupling shaft 21 projects into the extended hub 6 and is provided with a jaw clutch member 24 coacting with the clutch 7, the shaft 21 being axially adjusted to engage anddisengage these clutch members. The coiled spring 25 arranged within the hub 6 urges the coupling shaft to clutch disengaging position. .The shaft 21 is provided with a coupling member 26 which is threaded for adjustment upon the shaft 21 and secured in its adjusted position by the key 27 The coupling shaft when in driving engagement becomes a floating shaft, that is, it is supported only by the driving and driven parts with which it is engaged. This coupling member engages and is supported by the bushing 28 arranged in an opening 29 in the bracket 8 .when the shaft 21 is in position to disengage the clutch members 7 and 24. The purpose of this attachment is to accommodate the structure for variations which are found to exist in motor vehicles as they are in use, that is, variations in the same model or type of vehicle.

Splined to the shaft 15 is a sleeve 30 coacting with the coupling member 26, this cou- 8 and provides for disconnecting these shafts when the frame is removed.

The clutch members 7 and 24 are engaged by means of the lever 31 rotatably mounted upon the driven shaft 15 at the rear of the thrust collar 18 and has cams 32 coacting with the projections 33 on the frame cross member 16.

When the lever is shifted to the position shown by full lines in Fig. VIII and by dotted lines in Fig. VII the coupling shaft 21 is shlfted longitudinaly and its clutch member 24-. engaged with the clutch member 7. When the clutch control lever 31 is shifted to the position shown by dotted lines in Fig. VIII the shaft 21 is free to move forward under the action of the spring 25, thereby disengaging the clutch.

An oil cup 34 is provided for the bearing for the driven shaft 15 andthis also supplies suflicient lubricant to the clutch lever for the coupling sleeve. j

I provide a crank 36 with a spindle 35 adapted to be engaged with the driven shaft, suitable ratchet or throw-out connection not being illustrated.

When it is desired to crank the motor it is first necessary to engage the clutch member by means of the lever 31.

My improved pump attachment is highly BffiC18Ilt,-li3 being found that a motor such as in Ford automobiles is capable of handling a large volume of water without undue strain upon the motor. As stated, the parts are arranged so that they may be readily mounted or dismounted and the pump may be transported while mounted without undue strain on the vehicle.

While I have illustrated my improvements in detail as I have embodied .them in a pumping mechanism, devices other than pumps may be driven from the shaft 15.

I have not attempted to illustrate or describe various adaptations or modifications which I contemplate -as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.
