- The present invention relates to hoists adapted particularly for use on motor vehicles to elevate and support the transmissions thereof when work is to be done on the transmission, the clutch of I! the vehicle, or other parts adjacent thereto.

'An object of the present invention is to provide a hoist of this character which is made of several considerable parts so that the hoist may be quickly and easily handled, may beintroduced into small narrow spaces and set up in position, and which is so constructed that the several parts when assembled and correctly positioned will be relatively strong and rigid and capable of supporting considerable weight.

- Another object of the present invention is to provide a hoist of this character which may be fitted between the dash board and the front seat of an automobile, and is provided with adjustably connected parts for interbracing the side portions of the hoist and at the same time clearing the fiy wheel or clutch casing, and also clearing the front edge portion of the seat and other parts of the vehicle ordinarily in the way of hoist frames of conventional type.

The invention also aims at the provision of a hoist embodying the above characteristics and which at the same time has a Windlass support capable of adjustment so as to dispose the windv lass in direct line with the center of gravity of the 0 transmission case so that the hoist may be adjusted and then operated to lift the transmission case without undue tilting or displacement thereof out of its general vertical position with respect to the drive line of the vehicle.

36 With the foregoing and other objects in view,

the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

.iFigure 1 is a perspective view of a transmission hoist constructed according to the present invention and set up in position on the side bars of a 5 motor vehicle or the like, the dotted lines showing optional positions of the cross braces between the side frames for clearing parts of the vehicle ordinarily in the way. Figure 2 is a fragmentary vertical longitudinal section taken through the intermediate portion of a motor vehicle, showing the improved hoist applied thereto and connected to a transmission, the dotted lines showing a second position of the hoist,

Figure 3 is a fragmentary transverse section taken through the intermediate portion of the vehicle frame substantially on the line 33 of Figure 2.

Figure 41s a detail enlarged view, partly in section of the Windlass and its adjacent supporting parts, and v Figure 5 is an end view of the latter.

Referring now to the drawings, the improved hoist comprises a pair of side frames 10. Each frame 10 is made of heavy metallic bar stock bent substantially U-shape, the free ends of the frame providing legs adapted to rest upon the upper edges of the side bars 11 of a motor vehicle or the like, as'shown in Figure 1. The frames 10 are made of suitable thickness to impart the necessary strength thereto for supporting the weight on the hoist by supporting the transmission or other heavy devices adapted to be raised and. manipulated through the hoist. The frames 10 are of suitable length to conveniently fit between the dash board 12 of the vehicle and the front seat 13 thereof, as shown in Figure 2, and the side frames 10 are provided with pairs of lower and upper sockets 14 adapted to receive the opposite ends of cross braces 15 which may be so selectively disposed in either the upper or lower sockets according to the conditions met with in setting up the hoist.

, Each socket 14 comprises a sleeve or tube open at its upper end and which may be welded or as otherwise suitably secured to the inner side of the adjacent frame 10. Each cross brace 15 comprises a pair of overlapping rods having their opposite outer ends downturned for engagement in the selected sockets 14. A sleeve 16 is fixed to one of the rods 15 and the opposite rod is slidably disposed through the sleeve and secured therein when adjusted by means of a set screw 1'7. Any othersuitable adjustable connection may be provided between the rods of the brace 15. Thus, the frames 10 may be seated upon the side bars 11 of the vehicle frame and the rods 15 then adjusted as to length so as to extend between the frames 10. The hoist is thus adapted to vehicle frames which may vary in width. Any number of the cross braces 15 may be used for stabilizing the side frames 10 and preferably at least one cross brace 15 is disposed between the upper portions of'the frames 10, as shownin dotted lines in Figure 1, to interbrace the upper portions of the frames.

The free ends or legs of the side frames 10 are preferably reinforced by means of bottom braces 18 which may be in the form of rods welded or otherwise suitably secured at their opposite ends to the lower free end portions of the side frames.

Each side frame-10 is provided with a hanger 19 having a grooved wheel 20 in its upper end adapted to ride upon the upperbar of the side frame so that the hanger 19 may be easily shifted forwardly and rearwardly on the side frame. The hanger 19 is provided with a suspension strap 21 at its lower end which may be in the form of a sleeve which is swiveled upon the lower end of the hanger, so that the sleeve 21 may turn on the hanger when the latter is shifted to prevent binding of the grooved roller 20 on the upper bar of the frame. The hangers'19 are adapted to be brought into substantial register, as shown in Figure 1, and a cross bar or tube 22 is mounted through the straps 21, and the bar 22 may be secured against shifting through the straps 21 by set screws 23 or the like so that the bar 22 provides a transverse support between the tops of the side frames.

The bar 22 is relatively strong and heavy and is adapted to support a Windlass bracket 24 in the form of a sleeve slidable along the bar 22 and held in adjusted position by a set screw 25. The bracket has outstanding and downturned arms carried by the sleeve, the lower endsof the arms providing spaced apart bearings for a shaft 26 upon which is secured and wounda chain 27 or the like adapted to engage about the transmission or other article to be raised, and which may have a coupling hook 28 on its lower end.

The shaft 26 extends through one end of the Windlass bracket and carries a handle 29 in the form of a crank adapted for use in manipulating turning the shaft 26 to wind the chain 27 thereon. A ratchet wheel 30 is secured to the outer portion of the shaft 26 and is engaged by means of a gravity actuated pawl or dog 31 pivotally mounted upon the adjacent arm of the bracket.

In use, the side frames 10 are independently set up on the side bars 11 of the vehicle between the dash board 12 and the seat 13. The side frames 10 are located opposite the transmission and in suitable position for receiving the cross braces 15 to interconnect the frames.

In positioning the side frames 10, as shown in Figure 2, where there is ample room to place the frames as shown in full lines the bottom forward brace 15 may befi-tted in the lower sockets 14 and the rear brace 15 may be placed in the upper sockets. Where the construction of the vehicle is such, and it is desired to position the side frames 10 closer to the dash board12, as shown in dotted lines in Figure 2, the inclinedfoot board and clutch housing interfere with the positioning of the lower brace 15, and this brace may then be fitted in the upper sockets 14, as shown in dotted lines in Figure 1.

The hangers 19 are moved along the top rails of the frame 10 so as to position the cross bar 22 substantially intermediate the ends of the transmission. The chain 29'is now released by raising the dog 31 and admitting of the rotation of the shaft 26. The chain 27 may be of any suitable type and if of the type as shown, the hook 28 is secured to an intermediate portion of the chain 27 to loop the same about the transmission. The sliding bracket or sleeve 24 maybe moved along the cross bar 22 so as to support the Windlass at the desired point over the transmission.

The handle 29 is now turned so as to rotate the shaft 26 and wind the chain 27 thereon to raise or support the transmission.

desired point 'over the transmission or othermechanism to be supported or raised.

It will be noted, particularly from Figure 5, that the shaft 26 has 'a non-circular shank or end portion upon which the handle 29 is mounted. The handle 29 is provided with a correspondingly shaped opening so as to detachably engage the shank of the shaft 26 for turning the latter. 0f

course the handle 29 may be fitted to either end of the shaft and the shaft may have any other suitable construction at either end to receive the handle, a wrench or other suitable tool for manipulating the shaft in close places.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
