Application'filed October 20,1921. Serial No. 509,055.

To all w 7mm it may concern- Be it hereby known that we, GEORGE LA- FEVER and BATES E. HAWLEY, citizens of the United States, and residents of Kelso, county of Cowlitz, and State of WVashington, have invented a new and useful Rim Tool, of which the following is a specifica tion.

This invention relates more particularly to devices for removing pneumatic tires from what are known as split rims and also for placing same thereon.

The object of this invention is to provide an exceedingly simple, light, inexpensive and efiicient tool for collapsing and expanding split rims without subjecting same to any twisting moment.

We attain these results in the manner set forth in the following specification and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation showing the manner in which the device is applied to a rim. Figure 2 is an end elevation of Fig. 1. Figure 8 is a side elevation showing the device in its position after it has collapsed a rim sufiiciently to permit the removal or replacing of a tire. In these three views the rim is shown in dotted lines as not being a part of our invention. Figure 4 is an elevation of the rim-engaging portion of the device taken along the line H in Fig. 3. Figure 5 is an enlarged view of the extreme rim-engaging end of a device showing the manner in which the rim-engaging portions may be formed to prevent accidental disengagement.

Similar numbers of reference refer to the same or similar parts throughout the several views.

Referring in detail to the drawing, we have constructed our device to make it ap plicable to an automobile rim 10 of the type which is provided with holes in the side flange 11 near its ends. Our device consists of a somewhat V-shaped handle member 12 whose open ends terminate in the U-shape portions 13. From the inner sides of the RIM- moor..

U-shaped members 13 project the studs 1 1 which are of a diameter capable of permitting easy entrance into the holes of the rim 10. It will be understood that rims not already supplied with these holes must have.

them provided if this device is to be used.

A bolt 15 passes through the closed ends of both of the U-shaped members 13 whch are kept from spreading by the thumb nut 16 which may be adjusted to accommodate various widths of rims. Where the bolt 15 is not used it may be desirable to employ a stud 1 1 having a slightly shouldered point 1& which will prevent the stud from slipping out of its hole when pressure is applied. The Ushaped portions are required only to enable the flange 10 to move without being obstructed by the member 12 itself. The use of the U-shaped member may be dispensed with if the studs 14 are lengthened and shouldered as illustrated in Figure 5.

The operation of our device is as follows: l/Vhen desiring to contract a rim it is necessary to insert the four studs 14 in their respective holes as shown in Figure 1 and then pull the lever 12 to the position shown in Figure 3 which will causethe lever 12 to lock itself the studs 14 and the point of rest 12 of the lever 12 with the direction of thrust from the rim itself. In some instances it may be found desirable to use the bolt 15 and its thumb nut 16 to insure the studs 14: remainslightly, owing to the relation of nating diiiicult and expensive parts and great weight and cost with a view of supplying the market with an exceptionally'low priced tool capable of being used without great muscular exertion. Wetherefore do not claim our device broadly but only within the limits set forth in the following claim.

We claim: the open ends of said forked lever being A riin tool consisting of a curved forked curved in the opposite direction from the lever adapted to lie along the inner side of closed end portion in a manner to permit the 10 the rim and having two-projecting studs on tips of out-turned rim-engaging flanges to 5 each inner side of the openend of said pass between said projecting studs.

forked lever, abolt means across the open GEORGE LAFEVER. end of said forked lever between said studs, BATES E. HAWLEY.
