To all whom it may concern .1

Be it known that I, JoHN Onnnnmn, a citizen of the United States of America, residing at Mount Gilead, in the county of Morrow and State of Ohio, have invented certain new and useful Improvements in Lifting-Jack Mechanism for Motor-Vehicles, of which the following is a specifica drum is operated by the running'of the sin.

glue the cables will be wound upon the drum so as to rotate certain pulleys which in turn having jacks connected thereto will move the jacks to operative positions for lifting the motor car from the supporting surface.

With these -and other objects in view this invention consists of certain novel combi-' nations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a top plan view of the liftin jack mechanism, together with the brake, as

applied to a motor car.

Fig. 2 is a rear elevation of the device.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2,,looking in the direction of the arrow and illustrating the jack memher in a lowered position as it appears in use.

Fig. 4: is a section taken on the line 44 of Fig. 3.

Referring to the accompanying drawings by numerals, 1 designates the frame of the motor car which is constructed of a plurality of longitudinally extending side beams 2 which are supported upon the bolsters 3 having the springs 4 which are in turn connected to the rear axle 5 supported by the rear wheels 6. The forward ends of these side beams 2 are connected in any suitable manner to the forward axle 7 carried by the forward wheel 8. The beams 2 are connect.- ed intermediate their ends by the cross-ba s 9, 10, and 11. The crank sh: ft 12 is intended to be used'with the engine, any form of which may, of course, beemployed in connection with this device without departing from the spirit of the invention and has mounted upon its forward end the friction pulley 13. The intermediate pulley 14 is carried by the bracket Lilsupported by one of the side beams 2, as shown in Fig. 1. This intermediate friction pulley 14 also engages the friction pulley 15 carried by the forward end of the operating shaft 16, which shaft 16 passes along adjacent one of the side beams 2 and is carried in any suitable manner by the bars 9, 10, and 11. The grooved sleeve 17 is slidably mounted, although keyed upon the shaft 16 and has the beveled gear 18 at one end. Therefore, it will be seen that as the engine is in operation and rotary motion is imparted to the shaft 12 rotary motion will be imparted through the frictional pulleys 13, 14:, and 15 to the shaft 16 so that rotary motion will also be imparted to the beveled gear 19 bymeans of the sleeve 17 keyed upon the Shaft 16. The stem 20 is carried by one of the side beams 2 as shown in Fig. 1, and

has the spool 21 rotatably mounted thereon.

This spool 21 isprovided with a pinion 22 which meshes with the pinion 23 carried upon the cross bar 10. The beveled gear 25 is in turn connected to this pinion 23, as also shown in Fig.1.

When the shaft 16 is inoperation and the sleeve 17 is moved alongthe shaft so as to permit the beveled gear 18 thereof to en? gage the beveled gear 25 it will be seen that rotary motion will be imparted through the pinions 22 and 23 to the spool 21. A forwardly extending operating cable 26 and a rearwardly extending operating cable 27 are secured to the spool 21 and extend therefrom so as to have the branch cables 28 connected thereto. These branch cables 28 pass between the spools 29 carried upon -the bars 9 and 11 so that the branch cables 28 will be held so as to be positioned in a central position with respect to the central plane of the frame, whereby the operating cables 26 and 27 will be directed so as to wind evenly upon the spool 21. There are also provided giiide spools 30 upon the side beams 2 so as to permit the branch cables 28 to pass around these guide spools 30 whereby the cables in passing around these guide s ools 29 and 30 W111 be pre t d m provided with enlarged openings 34 formed therein so as to permitthe axles 5 and 7 to pass through the housings for fixedly supporting the same. The branch cables 28 after passing around the guide spools 30 pass into the housings 31 as shown in Fig. 1, whereby the ends of these branch cables 28 will pass about the operating pulleys 36 carried within the housings 31. These housings 31 are also provided with alined threaded apertures 37 and 37' so as to permit the externally threaded jack stems 38 to pass through these apertures 37 and 37 and through the central threaded. bore 39 formed in the operating pulley 36.

Upon the lower end of the jack stem 38 there is carried a caster as shown in Fig. 3.

When it is desired to lift or jack up the motor vehicle the engine, of course, should be running so as to impart rotary motion to the shaft 16 as hereinbefore set forth. As the gear 18 willimpart rotary motion to the gear 15, and pinions 22 and 23 to the spool 21, the cables 26 and 27 will be wound thereon. As the cables 28 are drawn toward and upon the spool 21 they,,of course, will rotate the operating pulleys 36 and this action will cause the operating pulleys to move the jack stem 38 downwardly from the lower portions of the housings 31. Upon the continued rotation of the operating pulleys 36the casters 41 coming into engagement with the floorof the garage, the road, or any other supporting surface will, of course, lift the motor car so that the entireweight thereof will be. supported by these jacks. By this construction it will be seen that if at any time it is desired to work upon the tires, or when the car is not in use it is desired to remove the weight from the tires and thus prolong the life .of the tires, these jacks are to be used. As soon as it is desired tocause the stems to again support the weight of the car and move the jacks from operation the sleeve 17 may be moved so as to cause the beveled gears to be moved to a neutral position and at this time the weight of the car will cause the jack stems to be moved upwardly through the housings and thus operate the pulleys 36 so as to unwind the cables 28 therefrom. From the foregoing description it will be seen that a very simple and eflicient device has been constructed which is formed so as to constitute a lifting jack for motor vehicles which will easily lift cars by the running of the engine which will impart rotary motion through various gears and shafts to the winding spool, thus causing the cables to be wound thereon, which action by rotating the operating pulleys will drive the jack stems into the ground for the purposes above set forth.
