RIM-TOOL.

Specification of Letters Patent.

Application filed Batch 25, 1919. Serial No. 285,012.

To all whom it may concern Be it known that I, HA RYRUSH, a citizen of the United States, and a resident of Chinook, in the county of Elaine and State of Montana, have invented a new and Improved Rim-Tool, of which the following is a full, clear, and exact description.

The present invention relates to tools, and has for an object to provide a tool for straightening tire rims which have become bent in use.

In the drawings forminr a part hereof is shown an illustrative em odiment of the invention.

Figure 1 is a view partly in section showing a tool constructed in accordance with the invention applied to a bent rim in the act of bending the same upwardly into normal position;

Fig. 2 is a perspective view of the tool; and

Fig. 3 is a side elevation of a modified form of my invention.

The clencher rims of automobile wheels frequently become bent inwardly from normal position'as the result of rough use or accident. It then becomes necessary to bend the rim edge outwardly to normal position at the point where it has been damaged. The presentfinvention provides a tool designed specifically for this use.

The tool shown in the drawing comprises a handle 1 and a head 2, the head being slotted at one face, as indicated at 3, to provide upper and lower jaws 4 and 5. The upper and lower faces of the slot are preferably concave, and the slot is narrower at its open edge so that the jaw edges approach each other. The lower jaw also preferably extends slightly beyond the upper jaw and thus serves to determine the position of the tool as it is applied overthe edge of the rim the u er 'aw which in o eration .forms a fulcrum, t ins being given a position slightly farther out on the rim than would otherwise be the case.

The lower jaw 5 is cut away on a curve, as indicated at 6, so as to form a wedge which may be inserted beneath a rim edge which has been bent down relatively close to the body of the rim. The face 7 of the tool opposite the slotted face is formed to present a driving head so that the lower jaw acting as a wedge may be driven beneath a'downwardly-bent rim edge as occasion may require. The free end of the handle may be, as shown, bent to provide a tire tool, as indicated at 8 in Fig. 2.

In the drawing, the tool is shown in position applied to a slightly bent edge of the v rim 10, and in dotted lines is shown the normal position of the rim edge to which it is to be bent by the operation of the tool.

The engaging edge of the jaw 4 is preferably made relatively sharp to prevent slipping of the tool in use.

Referring particularly to the modified form shown in Fig. 3, it will be seen that the same includes, instead of the conventional slotted head, as illustrated in Figs. 1 and 2, a piece of material bent so as to form a rigid jaw 11 provided with a screwthreaded opening through its lower part, as indicated at 12. Such screw-threaded opening is out of alinement with the longitudinal axis of the handle 13 and is adapted to seat a thumbscrew 14 provided with a pointed end 15, adapted to engage the to of a rim, similar to the jaw 4, of the slotted tool illustrated in Figs. 1 and 2.

The terms upper and, lower are used in reference to the jaws to indicate respectively the upper and lower jaws when the tool is in the position shown in the drawings, but it is to be understood that these terms are used in a merely relative sense .for convenience of description.

It will be understood that modifications in the shape of the tool may be made without departing from the scope of the invention as set forth in the appended claim.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent: 4

As a new article of manufacture, a rim tool, consiting of a handle and a head, the head having a flat face to form a driving surface and having in the face opposite the driving surface, a slot forming upper and lower jaws, the upper and lower faces of the slot being concave and the open edge of the slot being narrower than the remainder thereof, the edge of the upper jaw being sharp to form a biting edgeand the lower jaw extending slightly beyond the upper jaw a d having its lower face curved to form a wedge to permit it to be driven beneath a bent rim edge.
