UNITED STAT-ES LEON W. BROWN, or NEW-YORK, in Y., AND rnrn'n A. easmuaiorm m -name:

TURN-TABLE,-

To all whom it may concern? Be it known that we, Leon Browmav citizen of the United States, residing at New York, in the'county of New York and State of New York, and Pn'rnn ARAsMUs, a citizenot the United States, residing at Paxton, in the county of Ford and State of Illinois,

have invented certain new and useful Im-fl provements in Turn-Tables; and we do dc clare the following-to be a fullg clear, and e ;actdescription of the invention, such asf will enable others skilled in the art to which it appertainsto make and use the. same.

This invention relates to new and useful improvements in turn tables for automobiles and more particularly to a ,device which will enable an automobile to be turnedin a limited space in a garage. A further object of the invention resides in providing a device which "derivesits power from' the wheels of an automobile. when the latter is properly positioned thereon. I

Still another object of the invention re-' sides in providing an improved means for; locking the table against movement at predetermined points in the rotation thereof. 1

A still further object resides in providing 5 a device which is'simple and durable in constructiom inexpensive to manufacture and onewhich will be very efiicient and s'eful h in operation.

- With these and other objects in view, ou-r .i invention consists in the novel-features of construction, combination and arrangement of par-ts as will be hereinafter referred to Fi 2 v see n on line 22, Fig. 1. Fig is a bottom plan view of the device,and Fig; 4 1s a fragand articularl ointed out in the specificas p y p i be hereinafter more particularly set forth. 7

85 having one end thereof mounted insaid 1' flange 7 and the opposite end which'proje'cts inwardly with respect to the flange to bemounted in a bearing. plate 11. Rotatably mounted on this shaft is a friction or drive f roller 12 which engages the surface of a, g track way 4 in the base plate to cause said- Secured on the underface of the table 6' I i I and arranged in parallel relation to one an ablyreceive-pairs of shafts 14, the latter being rotatably supported-in adjustable bears .105 bolts 14 passing therethrough and through the slots 13. A pair of shafts 1-1" is provided adjacent each end ot the anglepairs of'friction rollers carried on the shafts let, thus enabling said rollers and shafts to be rotated by objects receivedon said table and engaging said rollers.

Mounted on shafts it are sprockets 17 said sprockets being arranged in longitto dinal. alinement and ert-ending over said sprockets for engagement with the teeth thereof is an endless chain 18, whereby said shafts may all be rotated in the same direction, when said rollers 15 are rotated. The upper reach of the chain 18 is held in en gageinent "with the teeth of the sprocket 17 by havingcontact with the under-face of the table 6 and We have provided a bracket 19 on one of the bars 18 which bracket has a roller 20 on the outer end thereof, engaging the lower reach of said chain 18. This roller 20 retains said lower reach in engagement rvith the teeth of the sprocket 17 and thus a positive connection is had between all of theshafts.

The pairs of shafts it are arranged in a plane above the plane of the drive shaft 10 carrying the friction roller 12 and means is provided for driving said shaft 10 from one of said shafts 14-. To this end a worm 21 is provided on one of said shafts 14 adjacent the inner end of said shaft 10. A pinion is carried on the shaft 10 for engagement with the "Worm and thus it Will be seen that upon rotation of said shafts 14-, the shaft 10 will be also rotated to cause the friction roller to be rotated for engagement -vvith the track Way l. 'lhus said turn table Will be caused to rotate on the base plate 3.

As stated above, the rotation. of the shaft ll Will. cause said turn table to be rotated oli on the base plate and We have provided. a;

naeans for stopping the rotation of said table at predetermined points 1n the rotation thereof. To this end WE: provide a sleeve 22 on the outer shaft 14 opposite that having the Worm thereon. This sleeve has teeth or'tlie'like 24.- formed in the peripheral edges-thereof which are designed for engagement with pins or studs 25 provided on said shaft at oints beyond each end of said sleeve. This construction forms a clutch mechanism whereby when said sleeve is disposed in one direction the one end "thereof will engage the one pin 25 Whereas when said sleeve is c isposed in the opposite direction the other pin or stud 25 will be engagedby" the opposite end of said sleeve.

Mounted on the underface of the table 6 to depend therefrom is a stud 26 'WhlCll has fulcrumed tireon an angular lever 27, the fulcrum point being disposed intermediate the ends of sail lever. The inner end of said lever 22' has loose connection, through he medium of a pin and slot, with said sleeve or clutch member 28 and the outer end. of said lever which projects through a slot in the flange T is adapted for engage ment with a pair of stop members .29 which are arranged at diametrically opposite points on the base plate 3. The outer end of said lever 27 is oil-set as shown at 30 whereby to be readily engaged with said stop member 29 as will be seen. in the rotation of said turn table, said lever will engage said stop members Wherc v to 0. use said clutch memher to be disposed to engaging position and thus prevent the rotation of the shafts 1st and correspondingly stop the rotation of said turn table in the pit.

Mounted on the upper face of the table 6 at points diametrically opposed to one another are the guide tracks 31 whiclrenable an automobile to be properly guided on the device. lt will be understood that when an automobile is guided onto this table 0 be tween the track ways, each Wheel. of the machine will be received on a pair of friction rollers indicated in the drawing as so that when the wheels of the automobile are rotated the device will be set in motion. In operation assuming that a machine has been properly positioned on the turn table should it be desired to rotate said table so as to position said machine for exit from the garage and. assuming that the space in said garage is too small to enable said automobile to be turned as usual, it is only necessary to place the machine in gear so as to cause the wheels thereof to be rotated. Each wheel of the automobile, stated above, is received on. a pair of friction rollers 15 so that when said wheels are set in rotation, the rollers will be rotated on. the device and prevent the automobile from moving forwardly. 'l herotation of said rollers 15, however, will cause the shafts 1-1 to be rotated and the friction roller 12 engaging the track it will cause the complete'talole with the automobile thereon to be rotated. A pair of stop members 29 being provided at points diametrically opposite one another on the base.

plate, it will be seen that this turn table may only be rotated in an arc of 180 de grees. In rotating to this degree, it will be seen that the outer end of the angular lever 27 will engage one of said. stop members and cause said clutch member to be effectively disposed thus locking said shaft 14. against rotation and preventing the rotation of said rollers 15. The shafts 14, carrying the rollers 15, however,are allowed to rotate While the table is turning, coil springs 27 being employed to retain the levers 27 in neutral position. As soon as the rollers 15' llillll It may be here explained that the adjustable bearings herein described are employed for the purpose of rendering the device adjustable for cars having different wheel bases.

From the foregoing it will be seen that we have provided a simple, inexpensive and eflicientmeans for carrying "out the objects of the invention and while we have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, within the scope ofthe appended claims, without departing from the spirit or sacrificing any of the principles of the invention.
