To @ZZ 7072/071@ it 7a2/Cty concern,.-

Be itknown that I, FREDERICK IV. STANTON, a citizen of the United States, residing at IVaupaca, in the county of IVaupaca and State of 'Iisconsin, have invented certain new and useful Improvements in Irenchesg 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 malte and use the same.

My invention relates to a novel construction in a wrench particularly adapted for use on vehicles, the object being' to provide a device of this character which engages the nut within the hub and externally engages the hub with a yielding pressure to enable the nut to be removed and replaced by merely turning' the wheel secured by such nut; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating' my invention, Figure l is a central longitudinal section of a wrench constructed in accordance with my invention, showing' the same engag'ing' the nut to be removed and the hub of the wheel secured by such nut. Fig. 2 is a side elevation of the wrench. Fig'. 3 is a fragmentary rear elevation of said wrench. Fig. e is a side elevation of an interchangeable cup to lit nuts of various shapes and sizes employed in connection with my said wrench.

My said device comprises an elongated iiat plate A, provided at its ends with iianges B, which at their free ends carry sleeves O the inner ends of which are square and the outer free end portions .D of which are cylindrical. rFhe said plate A is provided between its ends with an elongated slot E, vwhich is adapted to receive the shank F of a cup G, varying in form and size to [it nuts of various forms and sizes employed for securing' the wheels of vehicles upon the axles. rIhe said shank F is provided with a perforation H to receive a Cotter-pin J, by means of which said cup is held in place in an obvious manner. In the square portion of each of said sleeves O a plunger l( of similar shape is longitudinally movable, said plungers being' provided in their outer ends with recesses to receive rubber shoes L, which project beyond the free ends of said plungers and are adapted to bear upon the hub of the wheel. The said plungers K are provided with cylindrical stems M, which pass through the cylindrical portion D of each of said sleeves O, through openings in the outer walls or heads N of said cylindrical portions, and at their outer ends receive crossbars O, which form stops for limiting the movement of said plungers K in one direction and afford means for drawing said plungers outwardly against the action of spiral compression-springs P, interposed between the outer ends of said plungers and said heads N of the cylindrical portions D of said sleeves O, said springs being relatively stiff, so as to cause said plungers to bear forcibly upon the hub of the vehicle.

My said wrench is operated as follows: A cup G having' been irst inserted to tit the nut to be removed and replaced, the said plungers K are drawn outwardly against the action of said springs P until the space between the shoes L of same is greater than the diameter of the hub to be received between the same. The device is then moved over the hub so that said cup Gr enters the saine and receives the nut, and when this has been effected the plungers K are released and will obviously engage the hub. In the event that the nut to be removed is very tight the wrench may be turned primarily by grasping one of said sleeves C in each hand until the nut has been started. By then turning the wheel the nut will obviously be removed and will be retained in proper relative position to be remounted while the operator applies grease to the axle, and by then replacing the wheel and turning same in the opposite direction the nut will be obviously replaced and may be finally tightened by again grasping said sleeves O as before indicated and giving said nut a final turn.

The rubber shoes L are advantageous, inasmuch asthey serve to prevent scratching of the 4hub by means of any slippage which may occur.

My device is very simple and by reason of the interchangeable cups G can obviously be applied to any vehicle.

I claim as my inventionl. A wrench comprising two oppositelydisposed sleeves, al connecting-bar holding the same rigidly in proper relative position, a spring-actuated plunger movable longitudinally in each of said sleeves and adapted to bear upon diametrically opposite sides of the hub of a wheel, handles on the outer projecting ends of said plungers, and a cup adapted to receive the nut to be removed and replaced disposed on said bar midway between said sleeves.

2. A wrench comprising a bar provided at its ends with ilanges and midway between its ends with a slot, two sleeves disposed on said flanges in alinement with eaeh other, a plunger disposed in each oil said sleeves, springs actuating said plungers to normally hold the same at the inner limits of their movements, handles on said plungers for moving the same outwardly against the action of said springs, and a cup adapted to receive the nut to be lturned having a ril) adapted to pass through said slot in said bar and he secured thereto.

3. The combination with a wrench comprising a har provided at its ends with lianges and midway between its ends with a slot, two sleeves disposed on said lianges in alinement with each other, a plunger disposed in each of said sleeves, springs actuating said plungers to normally hold the same at the inner limits of its movements, handles on said plungers for moving` the same outwardly against the action of said springs, of interchangeable oups adapted to lit nuts oil' various shapes and sizes provided on their end walls with ribs having openings therein and adapted to pass through said slot in said bar, and pins adapted to pass through the openings in said langes to hold said oups firmly in position.

In testimony whereofl have signed my name in presence ol' two subscribing witnesses.

FREDERICK lV. STANTON.
