AUTO TABLE AND GRANE' Application filed-October 31, 1.922.- Serial 'No. 598,101.

To all whom it may concerni Be it known that I, KELLY B. citizen of the United States, and aresident of New York city, in the countyoii New York and State 01' New York, have invented certain new and useful Improvements in.

Auto Tables and Cranes, of which the following 1s a specification.

This invention relates to mechanism tor placing a motor vehicle on a stand above the ground or floor, and for the purpose of facilitating inspection and operations upon.

various parts of. the vehicle,

The obje'ctotthe present invention is to provide a device of this character by means o t which an auto vehicle can be run or drawn up on the table or supported above the ground or floor, and which device is provided with means in the nature of a crane that will permit mechanism on the vehicle to be removed therefrom and swung to one side or beyond the vehicle.

A further object of the invention is to provide in such a device, means that will operate in the nature of a winch, to actuate the crane cable and which winch.. will also serve to draw the vehicle up on to the table.

In the accompanying drawing illustrating one embodiment of my invention Figure 1, is a perspective view.

Fig. 2, is a cross section on the line 2-2 of Fig. 1 at one end of the device,

Fig. 3 is a vertical section, partly in elevation at one end.

Fig. t shows a degree Y.

Fig. 5 shows the thrust plate.

Fig. 6 shows the mast step plate.

Fig. 7 shows a detail on the top of the crane. 1

Fig. 8 is a plan of the latter.

The device as shown comprises essentially two members, an auto table and a crane. The former is shown as composed of a pair of side members 2 and 3 that are shown as channel shape. At one end these bars are connected by a cross bar 4, and supported by upright bars 5 and 6 that rest on a bottom bar 7 which bars are shown as of channel form. At the other ends the bars 2 and 3 are supported by four upright bars 8, 9,10 and 11, which latter rest on a bottom bar 12. The two pairs of uprights oneach side are connected by short bars 13 and 14C. If desired the side bars may be supported by uprights 15 and 16 at the middle p rtion, that rest on angle bars 17 and 18.

HARvnY, a

I further provide inclined bars 19 and 20 at one .end attached tothe side bars 2 and 3, to run the vehicle upon to the side bars,

either under its own power or by means of a winch on the table. j

In Figs. land 31' show a winch mounted on the cross .bartat the middle portion. This comprises essentially a bracket 21- supporting a drum 22 tor thee-able '23. A lever swings at one side of the drum and car-; was 7 a pawl 25 that. engages the ratchet flange 26 of the drum. A stop pawl 27 on the frame also engagesthe ratchet 26. The

'cable 23. can be attachedto the vehicle and by swinging the lever, the car will be drawn up the inclined bars and'on to the side bars 2v and 3. I v

A brake lever 2 1 engages an asbestos lined brake band 2 F on drum 24 tor-easing carsdownthe inclined bars 19 and 20.

I further. provide a crane at the front end of the auto table, that can swing over the car and also to one side or the end beyond the table. This crane I also arrange to be and the plate has a central opening 34, as a guide tor the mast 38, designed and constructed to receive all the lateral and clownward thrusts under load. Below this thrust plate, is themast step plate 35, with the flanged ends 36, 36 bolted to the angle bars 30 and 31. This plate has a mast socket 37 at the middle. The crane proper comprises a mast 38"preferably tubular, whose lower end is stepped in the socket 37, and which projects up throughthe opening 34 in the thrust plate 32 as shown. The crane also has a boom with supporting stays 44.

thrust plate 32, at the circular opening 34' with the Y 41 loosely surrounding the mast 38. The other portionof the Y 43 is in the form of a stepv to receive the boom 39. The

latter extends upward and outward'and at the top is secured to a pair of flat bar stays 44 and 45, Whose opposite ends are secured to the top of the mast 38. 7

At the top of the mast 38 is mounted a sheave 46 between arms 417' and 48 on a bracket 49 extending into the mast, and a bolt 50 passes through the mast and this bracket, and the stays 44 and 45 are also secured by this bolt 50 to the mast. It will be observed that the grooved. sheave 46 can receive and guide the cable 23 that passes upward through the tubular mast 38 direct. ly from the drum 22 of the Winch and then the cable 23 passes outwardly over the stays.

A sheave 51 is carried by the bracket 52 secured in the boom 39 by a bolt 53 passing through the boom 39 and the bracket which bolt also secures the stays 44 and 45 to the boom 39. It will be seen that the cable 23' lined brake band 24 is also used to lower away any load on the cable 23.

It will be understood that the crane can swing on the vertical axis of the mast in its supports in the cross plates, so that a part of the car can be raised by thecable and then the cross arm swung outwardly to one side,

or over the end of the table.

It will be further understood that the same cable or another cable wound on the drum 22 will permit the same winch that operates the crane, to be employed to draw the vehicle upv on to the auto table.

What I claim is A crane composed of two upright angle bars, a cross plateat the top of the bars provided with a journal portion, a cross plate connecting the angle bars below said plate and having a socket portion, an upright tubular mast mounted to turn in said socket and in said journal, a bracket having a collar surrounding said mast on top of said upper cross plate, a tubular extension on said bracket inserted in the boom, a tubular boom engaging said bracket extension, a sheave bracket on the upper end of the boom inserted in the tubular boom, a sheave bracket at the upper end of the mast, a pair of bars connecting the upper end of the mast with the outer sheave end of the boom, a cross bar connecting said angle barsand a Winch on said cross bar arranged to oper-. ate its cable passing up through the said mast and over the said two sheaves on the said mast and boom.
