\TIRE-REMOVING TOOL.

to those versed in the art to which this inventionappertains that one of the greatest inconveniences experienced by automobilists is in removing a damaged tire for the purpose of replacing hoe, it being necessary, in removing tires of the 'socalled quick detachable clencher type, to compress the base flanges of the casing after the inner tube has been deflated, so as to free the locking ring from the rim and thereby release the detachable flange so as to permit the detachment of the latter.

With a knowledge of these conditions, my ii'ivention has for its primary object a simple, durable and eiiicient construction of implement, whereby the detachable -flange may be easily and quickly pressed inwardly so as to permit thelocking ring to be removed, and the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the follow- 5 ing description and accompanying drawing,

in which,

Figure 1 is a side elevation of my improved tire-removing tool, a portion of a tire and rim being shown in section with the device in applied position, Fig. 2 is-a transverse sectional view, the section being taken approximately on the line 2-2, of

Fig. 1, and, Fig. 3 is a detail sectional view on the line 3-3, of Fig. 1.

to in the following description and designated in the accompanying drawing by like reference characters.-

Referring to the drawing, the letter A designates the body portion of my improved tire-removing tool. the" same being formed in inverte'g-arch shapewith a cross from whi'hangularly disposed andsubstantially parallel arms 2 and 3 .exte'nd.

characteristic of strength, is preferably formed. with an inner laterally elongated marginal-flange 4 from which a web 5 projects, as clearly indicated in' Fig. 1. The arm of the body portion of-the device is formed on its inner edge with any desired number of preferably curved sockets or recesses 6, designed to engage one side of the *wheel rim, whent'he device is in "its operativeposition.

The arm 2 of the device carries a casing 7 which is preferably formed integral therewith and which is provided with a bore in which a plunger 8 isslidingly mounted. Therear or inner end of the *plpnger 8 is designed for engagement by the cam surface 9 which is formed on an actuating lever 10, said lever being provided with a handle 11 of any desired construction and being fulcrumed in the casing 7 on a screw 12 or similar pivot device. It Will be noted that end with the notch 9 which, when the handle 11 is positioned in longitudinal alinement with the casing 7, engages the inclined faces 8 and locks the plunger in its projected position. The locking engagement 8' may be easily broken when desired by jarring the handle 11. i

In order to brace the tool and to prevent the plunger 8 from slipping from the clencher detachable flange of the rim, I have provided an adjustable brace rod 13 which, in the present instance, is screw threaded, as

in an opening formed in the body portion A, the head or end of the brace rod being adapted to bear against the rinnas shown in Fig. 1 and being held in adjusted position preferably by alock nut 14.

' In order to adapt the device for rims of difierent widths, the body portion A'is conheld in difieiem adjusted positions relativeto eachipther. I a

From, the foregoing description m con-- nection with the accompanying drawing,

the .ope'ration and practical application of clearly illustrated in Figs. 1 and 2, to work structed in two sections. 1 In the present ems bodiment of the invention, the joint is made 1 in the cross bar 1, a portion of which is bi? furcated, as indicated at 15, to receive the the cam' surface 9 is provided adjacent one between the cam surface -9 and the plunger to recelve a bolt 17 or similar fasten y-, e,

my improved tire-removing tool will be apparent. In the practical use of the device, the arm 3 is engaged with one side of the rim and the plunger 8 is applied to the detachable flange which it is designed to remove, The brace. rod'lS is adjusted so as to engage the adjoining portion of the rim so as to prevent the plunger from slipping 3 when being pressed inwardly. The actuating lever 101s then'manipulated to force the plunger 8 laterally or outwardly against the detachable flange so that said ring will be pressed inwardly toward the opposite ring or side flange of the rim, whereupon thelocking fillet 01' ring may be easily detached and the tire removed. It will thus be seen that I have provided a simple and eflicient bodiment of my invention, it is to be understood that the invention is not limited thereto, but-"thatvarious changes may be'made in the construction, arrangement and pro ortions of the parts without departing rom the scope of the invention, as defined in the appended claim. i

What I claim, is I A tire tool for use in removing tires, including a body portion provided with spaced arms, one of which is designed to engage one side of a rim, the other arm being provided with a casing, a plunger mounted in said casing and movable toward the first named arm, the rear endof said plunger being formed with oppositely inclined faces, and an actuating lever fulcrumed in the outer end of said casing and providedwith a cam surface adapted to bear against the rear end of said plunger, the cam surface being notched adjacent one end-for engagement with the inclined faces of the plunger for the purpose of locking said plunger in its projected position.

In testimony whereof I hereunteaflix my signature in the presence of two witnesses.
