FENDER ROLLER Filed Nw. 15. 192s Patented May 27, 1930 UNITED STATES ALLEN PRESTON ASHER, F SANDPOINT, IDAHO A FENDER ROLLER Application filed November 13, 1928. Serial No. 319,081.

This invention relates to tools used for rolling outindentations or deformations in fenders or other sheet metal articles of this general character and particularly to tools of this typeA such as are used in garages and which embody two jaws with rollers at the endsand means for tightening the jaws so as tobring the rollers in approximate contact y with the fender to thereby rollout indentalo tions or deformations.

`One of the objects of the present invention is to provide a fender roller which is adapted to be mounted upon and used in connection with a spoke tightener of the character illustrated, described and claimed in Patent No. 1,669,899,grantedMay 15, 1928. The spoke tightener illustrated in this patent comprises a body formed with two jaws adapted to be disposed to embrace or partially embrace a tire rim" and having a screw-threaded shank passing through one of the jaws and engageablewith the rim to press it down around theend of the spoke, the body being provided with a handle. f

Another object ofthe invention is to so construct the fender roller that the two jaws may be detachablyengaged with the handle ofthe spoke tightener body and extend over and parallel to thejaws above and below the saine respectively, said jaws being provided with rollers at their ends and provide means whereby the screw of the spoke tightener may `be used for shifting one of said roller carrying jaws toward the other roller: carrying A further object of the invention is to provide `:means for adjusting the other rolleiI carrying jaw so as to dispose the roller carriedthereby either slightly ahead or slightly 4"@ behind the roller carried by the other jaw or `dispose the two rollersin approximate alinement and provide means whereby the upper roller inay be set ahead ofthe lower roller and then the lower roller fset ahead `of the upper roller and thus give a crown to the metal `worked on. j.

Uther objects will appear in the course of the following description. j

y. My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a fender roller constructed in accordance with invention;

Figure 2 is a section on the line 2-2` of Figure 1; i

j Figure 3 is a fragmentary top plan` view of the under arm and roller v V Figure 4 is a fragmentary elevation of th rear end of the lowerarnu;` V i i Figure 5 is an elevation of the the upper arm. i e i Referring to these drawings, 10 designates the body of the spoke tightener previously referred to as forming the subject-1natter of .Patent No. 1,669,899. This body 10 is provided with the upper jaw 11 and the lower jaw 12, this lower jaw being bifurcated at 13. The body 10 is provided at its rear with the handle 14.` o

Extending through the upper jaw 11 on 70 the body is the pressure screw 15 having a head 16 whereby the screw lnay be turned. The inner end ofthe screw is formed to carry a cap of the character' set forth in detail in the patent above referred to but whichit is not necessary to detail in the present application, this cap merely being used for the purpose of tightening therim and spokeof a wheel. So far I have described the construction whichis illustrated in said patent.

In carrying out my present invention, 1 provide the upper resilientarrn 17. This arm `extends parallel to thej aw 11 but in spaced relation to the same except at the rear end where the arrn is bent downward at 18 and 85 forked as at 19 so as to embrace the body 10 and seat thereon. The arm 17 is formed with an aperture through which the screw 15 passes so that as this screw 17 is turned downward, the arm 17 4willtbe forced down. The

rear endV of 6U upper arm 17 should be so formed as not'to touch the topof the body 10 between the` handle 14 and the power screw 15. The lower arm 2O which is also made ofresilient metal, at itsrear end conforms to and 9 extends along the under face of the bodylO as at 21 and is formed withahookwshaped portion 22 to engage around thehandlelli at the lower end thereof. Passing through the arni 2() is a T-bolt 23 carrying the nut 24, 100

. to each other.

this bolt being disposed through the slotJ 13 and the cross bar of the bolt resting upon the upper face of the lower jaw 12 in the manner s own in Figure 2.

The arm 17 carries a roller 25 and the arm 20 a roller 26. The roller on the lower arm should be larger than the roller on the upper arm and ordinarily the lower roller 26 should be about one-half inch or so closer to therbody 10 than is the upper roller 25.

These rollers are transversely convex as shown in Figure 3. It is to be particularly noted that the lower jaw 12 of the tightener 10 is curved upward` at its forward end on its under surface and that the lower arm while it conforms to the contour of the under face `ofthe lower jaw 12 extends straight outward and upward from this lower aw at a point about two inches from the bolt 23, thus ermitting the lower arm 20 to be ad juste upward by the nut 24 or by releasing the nut to permit this lower arm 20 to move downward under its own resilience.

The bolt 23 holding the lower arm determines the position of the rollers with relation When this bolt 23 is tightened, it raises the lower roller and shifts this lower roller nearer to the body 1() than the upper roller. lVhen, however, the bolt is loosened, the rollers will be shifted to a position directly opposite each other and if loosened further the lower roller will be shifted out beyond the other. Of course, these two rollers are relatively adjusted by the screw 15 and bolt 23 until they are brought into such approximate contact with the work as will cause any indentation or deformation to be flattened out by reciprocating the rollers 25 and 26 over the work.

The use of the device will be obvious. The arms are opened and disposed on each side of the work. The bolt 23 is then adjusted so as to properly adjust the roller 26 with relation to the roller 25 for the work to be done and then the power screw l5 is rotated to bring the rollers into a greater or less contact with the work. The operator then reciprocates these rollers over the work by means of the handle 14 until the indentation or deformation has been ironed out.

Assuming that the rollers are in position on the outer edge of a crowned fender and it is intended to force the tool inward across the crown of the fender, then as the rollers are climbing to the top of the crown, the body of the tool is kept as low as possible to start with and gradually raised as the top is reached so that when the rollers are at the top of the crown, the tool is approximately horizontal. As the rollers go down on the descending surface of the crown, the tool is raised gradually so that when the inner" most edge is reached, the tool is elevated fully.

It has been found in practice that if the rollers are adjusted so that they are directly opposite each other, the tendency is to flatten out the crown surface and they do not afford any opportunity to stretch dents out of the metal, but by setting the upper roller ahead of the lower roller and then setting the lower roller ahead of the upper roller, a. crown or reverse curve will be given to the metal Worked on, which has been found to be particularly effective. It will be seen that the arms are relatively long so that relatively deep work may be operated on and it will also be seen that the device is extremely simple and cheaply constructed as well as easily operated.

I claim 1. A fender tool of the character described, comprising a body formed with upper and lower jaws and a rear handle, a power screw passing through the upper jaw and having a head, a resilient arm operatively engaged at its rear end with the body and extending over the upper jaw in spaced relation thereto and through which said power screw passes, the arm carrying a roller, a lower arm engaged at its rear end with the body and carrying a roller at its free end, the arm conforming for a portion of its length to the under face of the body, and a bolt passing through the under jaw and through said lower arm, the bolt when tightened acting to urge the lower arm upward against the jaw and when releasedacting to permit the lower arm to shift away from the jaw.
