- 4 Claims.

This invention relates in general to lifting devices and more particularly has reference to an tus for lending facility to turning the wheels with which the steering of a vehicle is the same in confined areas'and for driving the elevated end of the vehicle sideward when the front wheels are raised. The apparatus forming the subject matter of this invention is a continuation in part of my 00- 10 pending application, Serial No. 350,685, filed March 28, 1929. and an, improvement on my copending application, Serial No. 357,254, filed April 22, 1929.

Previous to this time in operating a vehicle in such as are often encountered when parking on busy thoroughfares, extreme dificulty is sometimes experienced in turning the steering wheels of the car when momentarily stationary, while maneuvering for the desired positiening of the vehicle in a restricted area. In some circumstances, however, an available space istooconfined for allowing the proper positioning of the vehicle by manipulation of the steering wheels.

In areas of sumcient dimensions to accommodate a'vehicle, the rear end of the same may be directed into the space, although it is often impossible to, similarly position the front end.

In my application first mentioned, I have profor elevating the front wheels of a vehicle whereby the same may be easily turned in order to facilitate maneuvering for position in confined areas and in my succeeding application referred to, I have provided rotating 85 members on the surface contact portion of my elevating device whereby in areas too confined for longitudinal movement the elevated end of the vehicle may be rolled sideward into a space of suiiicient area to receive a car.

It will be apparent, however, that by reason of the high crown existingin many of the modern streets difllculty is, sometimes experienced in attempting to remove the vehicle from a space in which it had been so positioned; also the necesthe vehicle for pushing the same into a space may be attended by certain disadvantages. 1

An object of this invention is to provide an apparatus for simultaneously elevating the wheels 0 by which steering of a vehicle is effected whereby the elevated and of the vehicle may be driven sideward.

Another object of this invention is to provide an apparatus for simultaneously elevating the ,55 wheels of a vehicle by which the steering is effected whereby the elevated end of the vehicle may be driven sideward by connection with the motor of the vehicle.

Still another object of this invention is to provide an apparatus for simultaneously elevating the wheels of the vehicle whereby the steering-is efiected which may be driven sideward at a variable speed by connection with the motor of the vehicle.

A further object of this invention is to provide an apparatus for simultaneously elevating the wheels of a vehicle by which steering is effected whereby the elevated end of the vehicle may be driven opposite to vthe normal longitudinal line of travel of the vehicle in either direction by connection with the motor.

A still further object of this invention is to provide an apparatus for relieving the weight of a vehicle from the wheels by which steering is effected, which is adapted to maintain the vehicle elevated'by the weight thereof resting on the sai'ne.v Y

With these and other objects in view which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the amompanying drawings means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular con-f structions, which for the purpose of explanation, have'been made the subject of illustration.

The belt-42 intended for engagement with the pulley 27 on the upport and'the pulley 370a them, is cmssed for operating the pulley 2'! clockwise so as to move the elevated end otthevemcle to the right 1 3. The belt i-flf'inten'ded for connection with the pulleys 2s mounted-on the bottom of the support and the pulleyaa 43 a mounted over a of wandflpivotedin The arm 44 is'pivoted to the on the ends of which rod '74 acts to hold ,t 't a mflfle A policy is pivoted on the arm 45 opposite the pulley 52. The arms 44 and 45 are formed with. curved portions in the center and with stops 56 at one end.- The stops 56am adapted to contact with a block 5'7 held by a spring 5llswhich isfixed into position by a bolt 59 projecting through the frame. The opposite ends of the arms44 and 45 are connected to clevises 61 fixed on the end of cables. and 63, better shown'in Figur 1.

The cables are carried over pulleys 64 mounted on the head of the engine 8 on a frame work 65 and attached to pull levers 68 and 69, respectively, through connections 66. The levers extend through a guide 6'7 positioned above the fioor board 9.

It will readily be perceived that in normal position the unattached ends of the arms 44 and 45 will project downwardly, the stops 56 resting against the block 5'7. By pulling either one of the handles 68 or 69, the respective arms will be raised and the belt passing over the pulleys mounted thereon brought in contact with one of the pulleys fixed onthe crank shaft stub.

The operation of this invention may be readily understood by first having reference to Figure 5. The support formed by the arms 14 and 15 pivoted to the axle is normally carried in horizontal position above the clearance of the axle when use of the same is not desired. It may be so held by lockim the lever 25 as has already been described in my copending application. A plurality of guards '71 are mounted on the arms 44 and 45 to prevent disengagement of the belts with the pulleys carried thereby and similarly guards '72, mounted on the base of the support likewise serve to maintain the belts in position on the pulleys 2'7 and 28 when the belts are loose by reason of the support being raised. Also a spring '73 is mounted on each of the clamps 11 and 12 are carried a cross rod '74. the support is raised the the belts taut.

when use of the support is desired the same is lowered for contact with the ground and the vehicle driven backward, whereupon the rollers 23 and 24 positioned transverse to the longitudinal line of travel of the vehicle will grip the retaming surface and thus cause the vehicle to be raised upon the support. on continued backward movement of the vehicle the arms 14 and 15 of the support will pass over the center and contact with the edge of the axle, preventing further movement and ma taining the vehicle elevated by reason of the weight resting thereon. In this In this manner when position the weight of the vehicle on the front tires is relieved and the steering wheels may be easily turned whereupon the car may be driven of! the support by moving forward, and the operation repeated if desired.

If it is wished to move the vehicle sideward with the front wheels elevated, the end of the vehicle is raised in the manner already described, whereupon it may be pushed in either direction on the rollers 23 and 24 or by pulling either one of the handles 68 or 69, the belts 42 or 43 may be brought in contact with the pulley mounted on the crank shaft stub and the rollers thus driven by the motor.

If movement of the vehicle to the right is desired the lever 68 is pulled, whereupon the arm 45 is raised and the belt 42 brought in contact with the pulley carried by the crank shaft. The belt 42 is crossed and is adapted to move the roller 23 clockwise. Inasmuch as the rollers are and .30 rotatin connected by'a belt 31 mounted'on pulleys 29 therewith..,the same may be moved in unison. Ifmovement of the vehicle to the left is desired. the arm 44. as shown in Figure 4. israised by pulling the handle 69 connected to the. arm 44 by the cable 63. The belt 43 engaging the roller 24 through the pulley 28 iashilhus caused to engage the pulleyon the crank It is of c urse. to be appreciated that in operation the belts will not grip the pulley on the crank shaft so as to move at the same speed, but will merely slide with respect thereto, and by exerting the necessary pressure in pulling the handles, the elevated end of the vehicle may be moved to either side at a variable speed and only the distance necessary.

There is shown in Figure 8 another form of arm '75 carrying the pulleys over which the belts are mounted. In this construction the belt does not contact with the stub of the crank shaft but a roller 7'7 is substituted for the pulley carried thereby, described in the other figures. Also a roller '76 is fixedly carried by the pin on which the rollers 52 and 53 are mounted so that when the arm is raised the roller '76 is brought in contact with the roller '77 and the belts driven in a similar manner to that already described with reference to Figures 3 and 4. It will be apparent in this construction that wear occurs between the rollers '76 and '77 and not on the belts which are llsllfalnted out of friction contact with the crank There is accomplished by this invention an apparatus for simultaneously elevating the wheels by which steering of a vehicle is eifected whereby the elevated wheels may be easily turned or the raised end of the vehicle pushed or driven sideward at a variable speed by connection with the motor.

While I have shown and described the preferred embodiment of my invention, 1 wish it to be understood that I do not confine myself to the precise details of construction herein set forth by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.
