SPECIFICATION forming part of Letters Patent No. 388,176, dated August 21, 1888.

Application tiled February 15, 1888. Serial No. 264,121. (No model.)

To all whom, it may concern:

Be it known that I, Cnasnns E. BRADLEY, of Dawson, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Lifting-Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the I0 same.

My invention relates to an improvement in lifting-jaeks for vehicles.

The object of this invention is to provide a simple and inexpensive device by the use of which the wheels of vehicles may be removed and supported in place adjacent to and in a line with the axle-spindle, so as to facilitate the lubrication of the spindles and the ready replacement to normal position of the wheels upon the same.

A further object is to provide a vehicle lifting-jack that will be adjustable in its parts to suit different lengths of wheel-hubs and diameters of wheels, and thus render it available for general use as a wa on-jack.

\Vith these objects in view my invention consists in certain features of construction and combinations of parts, that will be hereinafter described and claimed.

Referring to the drawings,Figure l is a per spective view of the device. Fig. 2 represents the lilting device in position with an axle and wheel engaged by it.

A is a lever or bar, preferably made of inalleable or wrought iron. The lever is bent at one end, a, and on this extremity the block a is pivoted to permit a rocking movement of the block. The lower side of the block a is channeled lengthwise to afford a proper bear- 0 ing on the body of an axle, and as this block is intended to bear upon the painted and polished surface of the axle, its grooved side a" is furnished with a slightly-elastic facing, a which may be made of leather, vulcanized gum, or any other suitable material which is cemented or otherwise secured in place on the block.

It will be seen that the body of the lever A is flanged at its lower edge on each side, in

order to stiffen it and afford strength with- 0 outobjectionable weight.

Upon the lever A a depending limb, G, is mounted so as to slide thereon, the limb having an enlarged and perforated boss, f, formed on its upper end, said perforation being of such shape and size as to loosely fit the body of the lever. On the limb C an arm, 0', is adjustably secured at any desired point below the offset bend a, that is made in the limb, a set-screw, d, affording means for such an adjustment of parts.

Between the handle I) ofthelevcr A and the depending limb O a sliding bracket-arm, D, is placed, which is provided with a fixed spindle, D, atits lower end, and the length of the arm D should be so proportioned to that of the bent end a of the lever A that the free end is of its projecting spindle D will be about in line with the curved lower face ofthe block a, toward which this spindle projects.

In use the curved end a of the lever A is introduced between two spokes above the hub of a wheel that is to be displaced, the retaining-nut and washer of which have been previously removed. The block a is caused to rest upon the upper surface of the axle, and the limb O shifted to lie near the inner face of the wheel-hub E.

By a proper adjustment the arm 0 may be made to bear against the lower surface of the axle B, (see Fig. 2,) and the end k of the spindle D be brought into line with the axle-spindle c, a proper distance intervening between the spindle-points; or they may be placed in contact, if desired.

\Vhen the device is adjusted as just described, the operator raises the wheel E slightly to clear it from contact with the surface on which it rests by an upward-lifting movement of the handle I) of the lever A. The wheel E may now he slid from the axle-spindle 0 onto the other spindle, D, when the lever A may be lowered and the wheel allowed to rest on the ground or floor.

It will be apparent from inspection of Fig. 2 that when a vchicle-wheel E is removed and the jack is in the position shown the weight of the vehicle at this point will be transferred to the wheel and the lever A locked firmly to the axle and wheel, to hold the removed wheel E in an upright position adjacent to the axle-spindle c and in line with it, or having its box opposite the spindle. After the axle-spindle c has been lubricated, the wheel may be replaced readily by slightly raising the lever-handle b and sliding the wheel from the supporting-spindle D onto the axlespindle 0, when the device may be instantly removed.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a lever, of a dependinglimbhavingalaterally-projectingarm thereon and a bracket-arm having a spindle thereon, substantially as set forth.

2. The combination, with a lever, of a depending slidinglimb, an arm adjustably secured thereto, and a sliding bracket-arm having a spindle thereon, substantially as set forth.

3. The combination, with a lever provided with a pivoted block on one end, of a depending limb, a vertically-adjustable arm placed on this limb, a sliding bracket-arm mounted on the lever, and a spindle affixed to thelower end of this bracket-arm, substantially as set forth.

4. The combination, with a lever bent at one end, and a block that is hollowed on its lower side and is pivoted to rock on the lower end of the bent portion of the lever, of a depending limb which has an offset in its body, an arm which is adjustably located on this limb to project from one side, and a sliding bracket-arm provided with a spindle which extends from its lower end toward the block pivoted to the bent end of the lever, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
