To all whOm it may concern Be it known that I, FRED P. HoUsER, citizen of the United States, residing at Bully Hill, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Motor-Car-Actuated Power-Jacks, of which the following is a specification.

The object, construction and utility of my improved motor-car-actuated power jack, are herein set forth with suflicient clearness to enable those skilled in the art to which it most nearly relates, to make and use the same.

The object of this appliance is to provide means whereby a motor-car may be quickly and easily made available as a power plant, for the operation of various machinery, and more especially for such machinery as is usually employed about a farm, such as threshing machines, feed cutters, wood saws, pumps, etc.

The construction of my improved powerjack is clearly shown in the drawings which form a part hereof, the figures of which are as follows:

Figure 1 is a plan view of said jack. Fig. 2 is a side elevation of same, one of the frictional transmission pulleys being removed to expose other parts to view.

The'construction as here illustrated is substantially as follows: I provide a base which consists of two main members 1, 1, that are arranged parallel to each other, and positioned at a distance apart that is somewhat less than the distance between the rear wheels of an automobile: Said two members are secured together in any suitable way, as by the cross-pieces 2, 2. Extending upwardly from said members 1, and secured rigidly to each thereof, is an upright standard or member 3, 3; the height of said standards is somewhat greater than the height of the rear axle of an automobile, from the ground or floor-line. Pivotally attached to each of said standards is a jack-lever, 4c, 4; the shorter end of each of said levers is arranged to be placed beneath the axle of an automobile, when said ends are lowered so as to pass beneath said axle; then, by lowering the opposite, or handle end of said levers, said rear axle is raised so that the rear wheels 5 are free from the ground or floor, and are free to revolve: Said levers 4 are retained in the operative position, as shown Specification of Letters Patent.

Application filed April 10, 1916. Serial No. 90,211.

in Fig. 2, by the hooks 7, which engage the handle ends of said levers. Mounted upon each of the base-members 1, is a verticallyextending stand 8, which stands are each pivotally connected at its lower end to its respective base member in such a manner that the upper end of each of said stands is free to swing toward or away from the axle 6,the outer position of said stands being shown by dotted lines. Each of said standards carries, in proximity to its upper end, a bearing or box 9 for the shaft 9 which extends across the frame and upon the outer ends of which shaft, friction pulleys 10, 10, are rigidly mounted or keyed to said shaft; said friction pulleys are adapted to be moved into frictional engagement with the wheels 5, whereby said pulleys are caused to revolve and to drive said shaft 9. Upon said shaft 9 is also mounted a belt-pulley 11, from which power may be transmitted by means of a belt to any machinery that is adapted to be so operated. For the purpose of imparting to said stand 8 said swinging movement which actuates the pulleys 10 into frictional engagement with the wheels 5 of the motor car, I provide the following means: Attached to the upper end of each of said stands is a chain 12, or any other suitable flexible element, which is adapted to be passed around the axle 6 of the motor car, the free end of said chain is then brought back and engaged by the hook 13, that is carried by a lever 14, when said lever is thrown upward to the position indicated by the dotted line 15; then, when said lever is moved downward to the position shown, said stand 8 is caused to move inwardly, and the pulleys 10 are thus caused to bear, with the required degree of pressure against said wheels 5 of the motor car, whereby motion is transmitted to said pulleys and to their shaft 9 and the belt-pulley 11.

It will be readily noticed from an inspection of Fig. 1 that the lever 14 is a portion of a continuous rod which is carried by and extends across said stand, and is provided with a chain-actuating member 14: at the side of said stand opposite to the member 14: By this arrangement, both of said pulleys 10 are caused to bear with an equal pressure upon the respective wheel by which it is driven.

I claim the following:

A motor-car-aetuated power jack com- 10 adapted to actuate said stand into said operative position and to retain the same therein as desired, and a belt-pulley rigidly mounted upon said shaft.

In testimony whereof I afiix my signature in presence of two Witnesses.

FRED P. HOUSER.
