Application filed April 5, 1918. Serial No. 228,845.

To all whom it may concern:

.Be it known that I, CHARLES B. HEIM, a citizen of the United- States, and a resident of Marco, county of Greene, and State of Indiana, have' invented a certain new and useful Tire-Vuleanizer; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to vulcanizing tools and is designed, primarily for applying a patch to the inner tube of automobile tires. One feature of the invention is the provision, in connection with a work holding frame, of a clamping foot, and a cam lever for operating the clamping foot for raisin and lowering the same. A further eature of the invention is the provision of a pin or roller on the shaft on the clamping foot for cooperation with the flange of the cam portion of the lever for raising and lowering the clamping foot and holding the same in lowered or elevated position. i

A further feature of the invention is the provision of means for removabl securing the clamping lever to the frameo the device to position the same directly over the upper end of the shaft and the clamping A further feature of the invention is the provision of means for adjusting the clampmg foot with respect to the shaft carrying the same...

The full nature of the invention will be understood from the accompanying drawings and the following description and claims Figure 1 isfa side elevation of the vuldevice showing same in operation in full nes and the position of the lever in inoperative position by dotted lines. Fig. 2

is a sectional view as seen on line 22 of Fig. 1, and Fig. 3 is an elevation of a sli htly modified form of device.

eferring to the drawings in which similar' reference numerals designate correarts throughout the several views, 1 in icates a frame which is substantially U-shaped, one arm thereof having a base 2, while the opposite or upper arm is provided with a socket 3,-said socket being positioned above and in line with the axial center of the base 2. Slidably mounted through the socket 3 is a shaft 4, to the lower end of which is adjustably secured a clamping foot 5, said foot being designed to engage the peripheral flange 6 of a fuel cup 7, and direct downward ressure thereon when desired. The clamping foot 5 is secured to the end of the shaft 4 by extending a screw 8 upwardly through the axial center of the lclam ping foot and into a threaded recess or socket 9 in the lower end of the shaft 4 and in order to increase or decrease the len 8 is made of su cient length that washers I 10 may be introduced around the screw between the end of the shaft and the clamping foot. In this manner it will be seen that the greater the number of washers placed between the end of the shaft and clamping foot, the greater the length of the shaft, thereby obtaining a greater degree of pressure upon the shaft and clamping foot.

Extending upwardly from the frame 1 is a bracket 11, to which is pivotally attached a lever 12, said lever having a cammed head 13 through which extends a ivot pin 14, said pivot pin being threadhd into the h of the shaft, the screw bracket 11, so that the lever can be quickly removed or attached. Extendin laterally around the edge of the cammed ead 13 is a flange 15which is eccentric to the ivot pin 14, the outer face of said flange eing esigned to travel. over and engage the upper end of the shaft 4 to direct downward ressure thereon when the lever is in its owered or operative position.

In order to raise the shaft 4 and the clamping foot attached thereto through the medium of the lever 12, the upper end of the shaft 4 is provided with an angular extension 16, the vertical arm 17 of which pro jects above the inner face of the flange 15 and carries a pin or roller 18, said roller projecting over the flange so that when the lever is thrown upwardly to the position shown by dotted lines in Fig.1, the shaft 4 and clamping foot 5 will be elevated, the curvature of the flange being such as to hold the shaft and clamping foot in elevated position when the lever is thrown upwardly its full distance. I

The flange 15 is also so curved that when the lever is thrown downwardly or to the position shown in full lines in Fig. 1, the clamping foot will be pressed tightly against the' fuel cup 7 and the material tightly im pinged between'the cup and the base 2, the.

flange 15 locking the clamping foot and I a. screw extending through said foot; and

shaft in clamped position. Y cy In Fig. 3 of the drawing a modified form 5' of the device is shown, and i 1 this-instance the upper end of the shaft 4 is pivotally attached to a walking beam firucture ld thefl i -extending through an elongated slo -l21 'inlthe'j end of the walking beam 19, so as to permit swing.-

pivot pin 20 for the s ing movement of the b eamQ g The walking beam is pivoted at its center to a standard 22 Whichprojects upwardly from the upper arm of the frame 1, the op-, posite endof the walking beam from the" end attached to the shaft 4 having a lever- 12' pivotally attached thereto,;said lever having a cam-med head 13 which cooperates with theframe 1 for rocking the walking the clamping foot 5" from the'fuel' cup" 7",

I the weight of said lever will hold the clamp-' ing foot in its elevated position, In this device' washers 10 are also' provided for lengthening or shorteningthe-shaft 4?, the

- remaining parts of the modified-form or device being the. same as shown in the pre tofsaid bracket, a laterallyuextending flan e I on said lever adapted to extend over and rent pressure on said shaft, said flange being "ferred form. e

of a' shaft vertically-slidable through said socket,'a clamping foot carried by'the lower end of the shaft, means to adjustably attach the clamping foot to the shaft, a pivotally mounted lever, said lever having a cammed head, and means to connect the lever with the shaft whereby when the lever is moved in-one direction the clamping foot and shaft will be lowered, and the shaft and clampingfoot raised whenthe lever is swung inthe opposite direction. 2.111 a vulcanizing device, the combination with a frame having a socket, of a shaft xtion' with a'frame having a laterally extending, flange beam on its pivot.
