HYDRAULIC HOIST FOB. AUTOMOBILES.

Application filed January 20, 1922. Serial No. 530,653.

To all 'whom t may concern.L

Beit known that I, LoUrs P. Fnoowloz, a at Brooklyn, in the county of Kings and t-ate of New York, have invented certain new' and useful Improvements in a Hydraulic Hoist for Automobiles, of which the following is a specification.

This invention relates to motor vehicles and more particularly .to the turning means therefor.

This invention has for its object the prof vision of means whereby a. motor vehicle may be turned in a short space so as to dispense with the necessity of running the vehicle forwardly andbackwardly a number of times when it is desired to turn around.

*A further object is to provide a turning device for motor vehicles which is simple to operate, durable in use, and cheap to manufacture. j Other objects and advantages of the invention will bejapparent during the course of the following description.

In the accompanying drawing formin a part of this application and in which 1ke numerals are employed to designate like `parts throughout the same,

Figure l is a side elevation of the inveni tion applied, parts being broken away.

Figure 2 is a group perspective of a power transmitting member embodied in the invention.

Figure 3 is a detail sectional view through the invention.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment ofthe invention, the numeral 6 designates a motor. As illustrated in Figure 1, the motor 6 is provided with a drive shaft 7 to which a clutch 8 is connected.

The invention forming the subject matf ter of this Qapplication resides in novel means whereby the forward portion of the vehicle may be elevatcd and moved in an arcuate path and the invention consists of a cylinder 8 adapted to receive Huid pressure from a pipe 9 lhaving control means preferably located adjacent the drivers seat of the vehicle so that when desired fluid pressure may be introduced into the cylinder.

When the fluid under pressure is introduced into the cylinder .8 the piston 12 in the cylinder is moved downwardly :for` in1- partmg a corresponding movement to the upwardly extending branch 14 of a horizontally disposed axle 15. A turning wheel 18 is provided with la hub 19 which is rotatably mopnted on the axle 15 and having a pinion 20 which meshes with the pinion 22 on the lower end of a shaft 23.

The shaft 23 is slidably extended' into a sleeve 26 and is connected thereto by inc ans of a radially arranged lug 28 which as illustrated in Figure 3, is slidable in a longitudinal slot or groove 30 in the inner wall of the sleeve. By reason of this construction the rotation of the lsleeve 26 will rotate the shaft 23 so that thewheel 18 will also be rotated for moving the vehicle in the proper direction.

The upper end of the sleeve 26 is formed with a gear 33 adapted to be engaged by a pinion 34 having a yhub section 36 feathered on the shaft of the engine. When the gear 34 is inmesh with thegar 33 the sleeve 26 is of course rotated for imparting a rotary movement to as wheel 18. However, the pinion 34 is rotated only when the improved turning device is in operation and the gear by means of a fork 39 having connection with a crank arm 40. The cranky arm 40 is connected with an adjusting rod 42 having a handle 43 arranged adjacent'the operators seat. With reference to Figure 1, it will be seen that -the adjusting rod 42 is movable through the dash 46 of the vehicle and is provided with locking means for engagement with a holding member 48 mounted on the dash.v

In operation, when it is desired to turn the vehicle, fluid under pressure is introduced into the cylinder for depressing the piston and thereby elevating the forward portion of the vehicle. When the forward portion of the vehicle has thus been elevated, the gear 34 is moved into mesh with the pinion 33 and the operation of the engine rotates the wheel 18 so that the vehicle 1s .turned to the desired extent. When the vehicle has been turned the gear 34 is released `from engagement with the pinion 33 and the Afluid under-pressure is allowed to escape from the cylinder 8 1 so as to allow` 34 may be moved to its inoperative position luc rigidly connected to the cylinder 8 by a connecting bar 50. The upper portion of the sheath is provided with anti-friction elements 53'which contact with the under side of the gear 53 whereby to reduce friction between the gear 33 and the sheath to a minimum. The sheath 49 forms'a' reliable means for su porting the sleeve 26 and for The combination with a vehicle having an en 'ne provided with a drive shaft, of a,

cy inder carried by the vehicle adaptedto receive fluid under pressure, `a horizontal axle having one end extending upwardly and provided with a piston within said cylinder, a ground contact7 Wheel carried by theel other end of said axle, a vertical fshaft carried by said horizontal axle for turning movement with relation thereto, beveled gears connecting said horizontal axle and said vertical shaft, a housing about the. upper end of said vertical shaft, a gear carried by said housing feathered to said`vertical shaft Yadapted to permit said shaft to slide bringing said second gear in mesh with said gear carried by said housing forJ driving the ground wheel. n In testimony whereof,-I have affixed my signature in the presence of two Witnesses.
