WILLIAM IVI. lI-IAYNIE, OF NEWIN'AN, GEORGIA.

VEHICLE-J ACK.

To all whom t may concern.'

Be it known that I, WILLIAM M. I'IA'YNIE, a citizen of the United States, residing at Newnan, in the county of Coweta and State of Georgia, have invented certain new and useful Improvements in Vehicle-Jacks, of which the following is aspeciication, ref erence being had therein to the accompanying drawings.

The invention relates to an improved vehicle jack and more particularly to a device of this nature especially adapted and useful in elevating and supporting automobiles to remove the weight from the tires when the automobiles are stored and for other pui'- poses.

An object of the invention is to provide an improved device of this nature of very simple and inexpensive construction that will be strong and eiiicient in use.

The invention broadly comprehends a vehicle supporting frame with pairs .of elevating and supporting levers connected to the frame and adapted to be swung or rocked to vertically adjust the vehicle supporting frame, and a further object of the invention is to provide improved manually operable mechanism to rock the levers for raising and lowering the vehicle supporting frame, and for maintaining the vehicle frame in 4its elevated position.

A further object of the invention is the provision of improved manually operable mechanism providing for the rocking of the elevating and supporting levers to effect a gradual lifting of the frame and tlie'easy manual operation of the device in handling heavy weights, and also providing for the quick adjustment orraising and lowering of the vehicle supporting* frame in dealing with the lighter weight vehicles.

The invention, with other objects and advantages thereof and the particular construction, combinations and arrangement of parts comprising the same, will be understood from the hereinafter contained detail description, when considered in connection with the accompanying.drawings, forming part hereof, and illustrating a preferred embodiment of the invention.

In the drawings: f .j i v Figure 1 is a side elevation of a vehicle jack constructed in accordance with the present invention, the vehicle elevating and supporting frame beingV shown in elevated position in full lines, and the lowered po- Specification of Letters Patent. Patented July I7, 1917.

sition of the frame and the elevating and supporting levers being indicated in dotted lines.

Fig. 2 is a top plan view of the forward portion of the device.

Fig. 3 is a section taken on the line 3--3 of Fig. 1,

Fig. 4; is a section taken on the line 4.-4; of Fig. 2.

Fig. 5 is a detail view of part of the vehicle supporting frame.

In the drawings, I have illustrated, by way of example, a particular embodiment of the invention but it will be understood that variations and minor changes of the particular construction shown, as will appeal to those skilled in the art, may be made without departing from the broad principles of the invention.

rI`he particular construction illustratedrin the drawings comprises a base or supporting bed composed of two longitudinal sills or members each of which is made up of two beams 1 1 of angle iron arranged side by side with their ianges 2 2 vertically dis posed adjacent each other, and their flanges 3-3 extending horizontally providing bearing surfaces. The beams 1 1 of each of the longitudinal sills or members are spaced a slight distance apart by blocks 4, and the parts are rigidly fastened together by front and rear transverse tie rods 5 and nuts 6, the ends of the tie rods extending through openings in the vertical iianges 2-2 of the beam 1-1. 7 designates an additional transverse brace member' of angle iron suitablyr secured to the longitudinal members near the front end of the base.

' The vehicle supporting frame consists of two longitudinal members each made up of a pair of metal beams 8--8 and having aXle engaging seat ymembers 8a at their outer ends. 9 designates spacing blocks between the beams 8-8 of each longitudinal member,

and the longitudinal members are rigidly secured together by front and rear transverse tie rods-lO-IO'and nuts 11, the ends of the tie rods extending through suitable openings in the beams. The tie rods 10 inter mediate their endsv are preferably bowed or curved downwardly, and the beams 8-8 are also depressed intermediate their ends, as shown, to provide clearance for the underframing and the connected mechanism of automobiles so that the Vmembers 8a on the straight end portions of the beams @3e-8 can vated position.

be freely engaged with the front and rear saxles of the automobile. Y

1-2 designates levers for elevating and' supporting n the vehicle frame. `The levers. 12 are arranged in pairs and pivotally connectedat opposite ends with the base and ver members'of the base and vehicle supporting frame, the tie rods serving as pivots for the levers. Guide frames are providedl for lthe "pair of levers at the front end of the sup# Each guide frame consists porting frame. of a pair of curved bars13 rigidly secured at'their end portions to one ofthe longitudinal members of the base opposite to each other and in spaced relation to permit the levers to operate therebetween. An advantageous connection of the curved guide bars with theibase is obtained by offsetting the end' portions of the bars 13 inwardly and securing the same `together by rivets or the like tothe angle beams l in the spaces thcrebetween.

I fThe-levers 12 are adapted,r to be rocked fromlthe position indicated in dotted lines in Fig'. l of the drawings to elevate and support the vehicle frame" in the position indicated'in full lines in Fig. 1 to lift an automobile from the grou-ndr and support the same to remove the weightl of the vehicle from the tires thereof for storing purposes or in the case of overhauling or repair work, the motor vehicle being adapted to be positioned above the vehicle frame so that the straight end portions ofthe vehicle supporting frame will engage the axles of the vehicle and elevate and support the vehicle when the vehicle Vframe is raised to its ele- @n the guide frames Vvare stopsI 14 ari ranged to be engaged by the forward pair of so 'provided Vfor rocking the levers 12 to raise f levers when they are swung to an up-right gposition. VStops 15 are also provided to limitthe downward movement of the levers.

The stops 14: and 15 are each formed by av block 1G secured between the curvedy bars 13 Vof'the guide frames, said curvedbars being provided `with oppositely disposed outwardlyoffset portions forming pockets in whichl the stop blocks are' secured byV rivets orthe like."` f

'i A particular'important novel feature of the invention reside's'in lthe'special Vmeans and lower' the vehicle supporting frame.-

' The improved mechanism Vfor this purpose comprises a shaft'l? mounted for-rotation at the front of thebase, said shaft extending transversely of the base, the ends of the shafts engaging suitable bearings provided on the longitudinal members 1 of the base. On the shaft 17 are two crank arms 19 located near opposite sides of the base, the cranks being disposed parallel to each other. Pivotal link connections 20 are provided between the outer ends of the crank arms 19 and the ends of the longitudinal members of the vehicle supporting frame. The cranks and levers are so proportioned that when the elevating and supporting levers 12 occupy an up-right posi-tion the cranks extend in longitudinal alinement with the links 20, the construction providing in this particular, locking means for maintaining the vehicle support-ing frame in its elevated position. Keyed to the shaft is a ratchet wheel 21, and 22 is a lever rotatably engaging the shaft at one end and held in position adjacent the ratchet wheel in any suitable manner for instance, by a collar 23. Pivotally mounted on the lever a pawl Z-t adapted when the lever is oseillatod in a forward direction to coperate with the 'atchet wheel 21, to rotate the shaft. 25 designates a gravity pawl for the ratchet wheel, said pawl being pivotally mounted on the forward transverse angle member 7. The ends of the shaft project a short distance from opposite sides of the base and iixedly secured thereto are operating levers Q6.

It will be observed that this construction provides for a gradual lifting of the frame and the easy manual operation of the device in handling heavy weights, this being effected through the pawl and ratchet located centrally of the shaft, and also that provision vis made for the quick adjustment or raising and lowering of the frame through the operating levers 2G that are ixedly secured tothe ends of the shaft.

It will also be noted that the special construction of the base or supporting bed, the vehicle supporting frame and the particular location and connection of the elevating and supporting levers provide a very simple and strong construction which can be manufactured at little expense.
