TIRE-"BOLvT-WRENCH MACHINE.

SPECIFICATION formingpart of Letters Patent No. 790,587, dated May 23, 1905.

Application led June 14, 1902. Serial No. 111,661.

To all whom t may concern:

Be it known that I, CLEMENT L. V. MUND- HENK, a-citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements vin Tire-Bolt-Wrench Machines; and Ido 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 appertainsto make and use the same, reference being had to the accompanying In the annexed drawings, illustrating this4 invention, A is a metal frame cast in one piece having a backvertical su pporting-plate m, with side projections m at the top and bottom, with l plate.

slotted openings for the purpose of securing the frame rigidly to a suitable object for use, a pair of 'jaws for the pivoting-lever extending outward from the face of theback plate 'm at the top, joined to said back plate m below said jaws, a top plate m extending outward, having near its center suitable openings f to receive and supporta vertical bevel-gear wrenchshaft C, said plate m being joined at its outer extremity to a face-plate m3, which projects at right angles downward. Upon the upper end of said front frame-plate is a fixed jaw d, adjustable by means of a set-screw, said front plate having at convenient points means of attaching and supporting the bevel-gear shaft and lever B. Extending outward from the lower end of said back plate m to the lower end of said front plate m3 is a bottom plate mi, forminga union at right angles With said front Extending outward from the 'back plate at a point alittle below the top plate m is a plate m2, parallel with said top plate, but

extending only part way, said plate having near its extremity a suitable shaft-opening c, l corresponding to and with the one, f, de-

having at its upper end a jaw d, provided with' a cutting-blade it, inserted in an opening upon its front face corresponding to the fixed jaw el and cutting-blade, as described as a part of the front frame-plate m3, said lever being provided at its lower extremity with a yoke V, as shown in Fig. 3, constructed to engage an eccentric located upon a shaft, hereinafter described, operating in conjunction with said lever, said lever having at a convenient point a suitable opening for pivoting and operating in conjunction with eccentric-shaft to be described, producing a cutting device for removing the projecting end of a bolt. D is a short metal cast link-lever having a pivoted end upon one end engaging the jaws upon the face-plate heretofore described, said link-lever having at a point on its under side and directly over the center of wrench-socket, Fig. et, hereinafter described, a dog j', at its other end a round bearing-pin engaging a lever E, operating in conjunction therewith.

In Fig. l, E is a metal cast lever having a slightly-curved handle end and downward and inward curved hook Z to engage the felly of a j wheel to form a fulcrum, said lever having at a convenient point a slotted opening extending through said lever in a plane with the round end of ,the short link-lever last described suitable to engage the round bearing .end of said short link-lever and permitting the adjustment of said curved lever-hook to different points on a felly when the machine is in use.V

Fig. 4: is a hollow shaft having at one end a wrench-socket to be used as a wrench, having IOO an opening on one side through which the disengaged nut may be discharged, the said shaft adapted to engage with and be operated by a train of bevel-gears working in a vertical plane fastened to a shaft and supported by the shaft passing through the frame-plates at convenient points below the top plate. Said shaft has as a part of its construction an eccentric conveniently located to engage a yoke V, Fig. 3, on a lever heretofore described, and acrank at right angles to a line of its location in the frame, Figs. l and 2. A bevel-gear engages the above-describedv gear, working in a horizontal plane at a point between the top plate and the one described as below it, Fig. 2.

I am aware that tire-bolt machines have been made with vertical and horizontal bevel-gear and shafts operating in conjunction with a nutwrench. I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is

In a tire-bolt-wrench machine the combination of a vertical metal cast frame A, having vertical and horizontal plates, a cutting-jaw upon the front face-plate, suitable openings in plates to receive and support a bevel-gear and shaft, a short metal link-lever pivoted to the jaws in the back frame-plate, said lever having a dog and round hearing end to engage with metal cast hand-lever E through a longitudinal slotted hole, said lever having a handle end and a curved hook end to engage with the felly of a wheel in use, a sq uare socketwrench with side opening and shaft, a lever having a pivotal center with a cutting-jaw upon its upper end to engage with a corresponding fixed cutting-jaw and a yoke upon its lower end to engage with a shaft having an eccentric thereon, said shaft provided with a bevel gear-wheel engaging with a wrenchsocket-shaft gear-wheel, said shaft operated by means of a crank and handle, substantially as speciiied.

In testimony whereof I have signed my name to this specilication in the presence oi two subscribing witnesses.

CLEMENT L. V. MUNDl-IENK.
