'llhe device iorming the subject matter at this application isa tool, adapted to be used in correcting distorted beads on the rim of a vehicle tire, and the invention aims so to construct the tool that it may he used either to bend outwardly, a head which has been too much bent inwardly, and, further, so to con struct the tool that it may be used as a term or anvil which, in connection with a hammer will bring about an inward bending oi a head which has been bent outwardly to too great an extent,

it is within the province of the disclosure to improve generally and to enhance the utility oi devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the descriptlon proceeds, the invention resides in the combina-- tion and arrangement of parts and'in the details oi construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in tho precise embodiment of the invention shown can be made without departing from the spirit oi? the invention.

lln the accompanying drawings:

Figure 1 shows in side'elevation, a device constructed in accordance with the inven-- tion, parts being broken away; Figure 2 is an elevationwherein the tool is viewed at right angles to the showing of Figure 1, parts being broken away; Figure 3 is a fragmental elevation showing one end of the tool in operation; and Figure 4 is a fragmental elevation showing the other end of the tool in operation,

The tool torming the subject matter of this application comprises a body 1 in the form or a bar, one end of which is thinned and curved to term a book 2, the bill of the hook terminatin adjacent to the longitudinal axis of the l to form a shoulder 4 on the end of the a l, outwardly out the end of the hill 3 as shown in Figure l the throat 5 oi the hook bein disposed at an acute angle to the axis of the dy 1 and comprising parallel inner walls 6..

in Figure d, the numeral '7 denotes a rim having a head 8 which has been bent inwardly too tar toward the rim 7. The edge of the head a is engaged in the threat 5 of the hook a and the bead 8,.obvious1y-may be bent out readily into the proper'position shown in dotted line in Figure d, Because the bill d of the hook terminates adjacent to the axis or the body It, the shoulder dconstitutes a means whereby the head 8 may be guided into the throat 5, the parallel inner walls 6 oi the hook 2 receiving the head 8 closely,

The opposite end of the body It is thinned and prolonged to term an anvil 9 which'is outwardly extended and is disused at an angle ot approximately 115 h respect to the body it, the outer end of the anvil 9 bein rounded as at 10, and there being a rounde heel or fulcrum ll at the point of juncture between the anvil 9 and the body it,

In Figure? there appears a rim 12 having a head it which is bent outwardly beyond its normal position. The rounded end 10 of the anvil 9 may be placed within the head 14 the heel or fulcrum ll resting against the rim 12. Then, through the instrumentality of a hammer 15, the bead i l may be shaped properly over the rounded end ll) of the an- Vll 9, it being observed that the anvil is tapered as at 16 from the body l toward the free end of the anvil so that the tool may be tilted on the heel ll thereby to permit the rounded end 10 of the anvil to be positioned properly within the distorted bead 1d,.

What is claimed is:

A rim tool comprisin a body provided at one end with an anvil w ich tapers from the body to the outer end of the anvil, the body being thinned to form the anvil, the outer end of the anvil bein rounded, the anvil projecting laterally wit respect to the body, the anvil being the sole lateral projection on the body between said end of the body and the opposite end thereof, there being a rounded heel at the oint of juncture be tween the body and t e anvil, the anvil be ing located at an angle of approximately 115 with respect to the body, whereby, when the heel is placed against the base of a tire rim, and when the rounded outer end at the anvil is engaged within the head of a tire rim, the body will be disposed at such an angle to the base of the tire rim that an operator may conveniently hold a hammer with one hand and pound the head over the rounded end of the anvil, and grasp the body of the tool with the other hand,

In testimony that I claim the -foregoing as my own, I have hereto aflixed lll ti in st ature. JAMES V DllN AR.
