PATENT! oFFicE .ELLIS E. ANDERSON, or MEMPHIs, TENNESSEE .AUTOMOBILE HANDLING DEVICE Appncation medfAug'ust 31, 1929. serial-No. 389,640.

Vrlhis invention relates. to an elevator forv raising automobiles-or other vehicles from a lower floor to higher iioors. `It has especial relation to a device for'raising aplurality of automobiles at thel same time and for posiy tioning them at progressively diderent floors. l Y v The objects of this invention are to providemeans for raising a number of automo- 1'0' biles at the same time to different ioor levels.

A further object is to generally improvek the design and construction of sucha device.

vThe means by which'. the foregoing and other objects are accomplished andthe man- '.15 ner of their accomplishment will Vreadil-y'be understood from the following specification on reference to the accompanying drawings,-

iny which.: I Y.

erably adjacent the ends -of

elevator platforms

25, 26, 27 and 28 whichareto be raised by them. Each of the beams is provided at one end with an upwardly curved extension 29preferably also of 'I shaped cross section, 5 which extensions are kprovided with bossesV or bearings 30. `These bearings are journaled on pins 31, which are carried by pedestals32..

The; pedestals 32 are supported on suitable foundation piers 33, and are so disposed that V the two ypins carried thereby are in axial tudinally along the beams..y A transversely opposite pair of jvoists thus carried, support the floor or platform of each elevator. These A shaped frames are vdesignated in the claims as supports extending rigidly upward from` the beams. Depending from each of the joists or from vtheplatform Vadjacent the Y I joists Vare A frames 37, which A frames lie.,

along sidethe beams and serve vas rigid members through which the horizontal position of the platforms mayg-be maintained.V ,Each 75V of theselatter A frames is pivotally connectedat its apex,as bypins 38, to struts 39 whichv I varedisposed-equal distances below thepin f .mountings35' ofthe platform andf which struts lie parallel fto V.the top of thegbeams.

Ast one end these struts are'pivotally connected as by pins 4 0'to pedestals 41.. The pins 40 lie inthe vertical plane ofthe beam pins V31, although they are laterally offset in order that the struts may vlie at thefside of .the

beams. It'will belseen'that the hinge `pins for each beam `and corresponding strut and the corresponding pair of platform pins lie `attheV cornersof a parallelogram with -rigid sides,so that when the Aouter ends of the beams are raised thus raising the platforms, cach of these platforms will at all times be maintained in horizontal position, provided such conditions initially exist. T he platform supports are spaced at sucli distance from the pins 3l, that when one of them is brought level with the particular floor with which it co-operates, the remainder of the platforms will be level with their respective floors. This condition will obtain when the distance from the pins 31 to the support pins 38 is proportioned to the distance of the floors vertically above the pin 38. Ordinarily the floors will be equal distances apart, in which case the distance between platform pins will be equal.

The beams 24 are connected intermediate their ends and ordinarily adjacent the middle thereof by cross girders l2 which in turn carry bearings 43 spaced apart. Disposed between these bearings is the upper end 44 of the ram 23 which is pivotally connected to them by a pin 45.

4G indicates diagrammatically a hydraulic pump and L7 an electric motor for driving the same. 48 is an oil pipe from the pump through one of the trunnions 2O into the cyl inder, and 49 a return pipe to an oil tank 50. 5l is a pipe from the oil tank to the pump. 52 is a control valve. The detail and operation of such parts being well known and not a part of the present invention, need not here be shown.

In using the device the beams are lowered b y the ram to a horizontal position, bringing all the elevator platforms level with the main floor. Any or all, of the platforms may then be loaded, as by the automobiles shown, and oil or other liquid forced by the pump into the cylinder, causing the ram to raise the beams upward around their pin centers, andV raisingv the elevator platforms Q5, 26, 27 and 2S respectively to the second, third, fourth and fifth floors. During such movement the struts 39 will maintain the platforms in horizontal position. lt will of course be understood that platform 28 may be raised and stopped at any one of the four floors, that platform 27 may be stopped at any of three floors, and platform 26 at either of two floors. 19A shown dotted, indicates the position to which the cylinder swings during the upward movement of the elevator. 23A indicates the eXtreme extended position of the ram, and 24A the corresponding position of the beams. 25A. 26A,27A, and 28A show the resulting positions of the elevator platforms and 39A the corresponding position of the struts.V The platforms are lowered by allowing the oil to return to the tank and the ram to descend.
