UNITED STATES JAMES V. CULLEN, OF CHICAGO, ILLINOIS. I

VEHICLE LIFTING DEVICE.

Application filed April 18,1922. Serial No. 554,598.

To all whom it may concern:

. Be it known that LJAMEs V. CULLEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Vehicle Lifting Devices, of which the following is a specification.

This invention relates to hoists or lifting devices and more particularly toa structure designed for hoisting automobiles to a desired elevation to permit convenient working on the parts of the machine which are accessible only from beneath the machine.

Another object of the invention is to provide a hoisting device as specified which is comparatively simple in construction, is strong and durable and by means of which a motor vehicle may be raised, by one person and which lifting mechanism is also designed to permit the lifting of oneend of the vehicle at a higher elevation than the other end of desired.

Other objects of the inventionwill appear in the following detailed description taken in connection with the accompanying drawings wherein:

Fig. l is a side elevation of the improved lifting device.

Fig. 2 is an end elevation of the lifting device.

Fig. 3 is a fragmentary vertical section taken on the'line 33 of Fig. 2.

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

Referring more particularly to the drawings, the. improved vehicle lifting device comprises substantially frusto triangularly shaped end supports 1 and 2 which are arranged in pairs at the ends of the lifting device and which are connected at their base by longitudinally extending supporting bars 3 and at their tops by supporting bars 4. The supporting bars 3 and 4 are braced intermediate theirends by vertical bracing bars 5.

Each of the substantially frusto triangular supports 1 and 2 has a guide structure 6 extending vertically therethrough at their altitudes and these guide structures each comprises spaced angle irons 7 and 8 hav ing parallel facing surfaces between which the ends of the lifting bars 9 extend as clearly indicated in Figs. 2 and 4 of the drawings. The lifting bars 9 are connected by longitudinally extending vehicle supports 10.0ne of which is positioned at each side of the lifting device adjacent the guides 6.

Substantially U shaped clips 11 engage about the lifting bars 9 adjacent to the guides 6 and they have bolts or pins 12 carried thereby upon which connecting loops 13 are mounted. A set of elevating cables or ropes 14 are connected to the pins 12 carried by the clips 11 which are in turn connected to 'or mounted upon the lifting bar 9, move through the guides 6' carriedby the end supports 2 and these cables extend upwardly along the guide 6 and over sheaves 15, extending downwardly therefrom, about sheaves 16 and extending from the sheaves 16 parallel with the base of the lifting device to the outer lower corners of the end supports 1 where they pass about guiding sheaves 17, extending upwardly from the sheaves 17 to the drums 18 to which they are connected for winding thereon. The sheaves 15, 16 and 17 are supported by suitable supporting shafts 19 as clearly shown in Fig. 2 of the drawings. A second set of elevating cables or ropes 20 are connected to the drums 18 for winding thereon and extend upwardly from the drums about guiding sheaves 22 rotatably .sup ported by suitable shafts 23 at the tops of the supports 1. From the guiding sheaves 22, the cables 20 extend downwardly and are connected to the clips 11 which engage about the lifting bar '9 movable between the guides 6 of the 'end supports 1. k

The drums18 are mounted upon a shaft 24 whichis rotatably supported by suitable bearings 25 which are in turn carried by the outer sides of the end supports 1. The shaft 24 has a relatively large gear 26 mounted thereon which mesheswith a pinion 27 carried by an auxiliary shaft 28. A; crank handle 29 is mounted upon the shaft 28 to permit manual rotation of the shaft and consequently manual rotation of the shaft 24 at an increased power and decreased speed through the medium ofthe gear 26 and pinion 27. A suitable pawl 30 is provided which. engages theteeth of the pinion 27 to prevent back rotation of the pinion and consequently unwinding rotation of the drums 18.

A suitable incline (not shown) may be provided for permitting a vehicle to be driven upon the vehicle supports 10 and then by winding rotation of the drums 18,these vehicle supports, and the vehicle supported thereon may be raised to any desired elevation within the limits of the guides (i, to

support the vehicle high enough to permit a workman to conveniently work on the parts underneath it. The angle bars 7 and 8 of the guides 6 are provided with a plurality of spaced openings 32 which are adaptedto receive bolts or pins 33 upon which the lifting bars 9 rest, the said, boltscooperating with the respective ropes or cables 14 or 20 for holding the vehicle in its raised position. Diagonal braces-34= and35 are provided for bracing and connecting theend supports 1 and 2 and these braces-are connected tothe end supports by removable lower bolts 36- and upper bolts 37. When. avehicle is driven upon the lifting device the bolts 37 are removed, and'the central connecting bolt 38'is also removed afterwhich the braces. are moved downwardly, pivotally upon the bolts 36 to permit the vehicle to be driven upon the vehicle supports 10 after which the braces 3a; and 35 are raised and extend diagonally, crossing each other intermediate their endsand the bolts37, and 38- arethen adj ,usted to securely holdithe bracesinplace. However, in case it isdesiredto work upon the ends of the vehicle, at which, time the diagonally extending. braces would be in the Way,these braces are positioned horizontally and they are provided with bolt receiving openings 39 so thatwhen positioned her-i zontally the bolts 36 will be lnS6PtQ(l#thIO11gh the brace 35, for securely connecting it in a.

7 supports 10, are shown. in dottedllines, supported; atran incline so asto permit one end of thevehicle to be raised higher than the opposite end and such adjustment is, per-l lnitted. by disconnecting. the loops 13-. from the pins 12and clips 11 at, the ends of the supports which are not tobe raised and 'thus by rotating the drums 18 in winding rotation, only one end of the vehicle will be lifted; 7

It, is, of, course, to be understood that the invention may be constructed in othermanners and: the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Havingthus described my invention what I claim is: g I

In a vehicle support, a plurality ofsubstantially frusto triangular shape end supports, braces connecting said supports,a pairv of vertical guides carried by each of said supports, lifting bars having their ends seated in said guides, vehicle supporting 7 bars carried by said lifting bars, cables de: tachablyconnected to said lift ng, bars, wlnding drums, means for rotating sald windingdnunis toiwind said, cables thereon or unwind therefrom for raising on lowering saidilifting -bars and vehiclesupporting bars.
