FENDER TOOL Filed Aug. 3, 1931 2 Sheets-Sheet 2 INVENTOR ent filed April 21, 1931, and serially nu'm all Patented Feb. 23, 1932 The invention relates to a fender tool, and

more especially tool preferably NIILO PESOLA, or rircmsune, MASSACHUSETTS FENDER TOOL Application filed August 3, 1931. Serial No. 554,871.

to an attachment for a fender of the type or style formingthe subject-matter of my application for patbered 531,821, the tool therein being designed for use in straightening sheet metal, particularly automobile fenders, radiators or other parts of automobiles or other sheet-metal structures.

The primary provision of an object of'the invention is th attachment of this character,

wherein the hammer of the fender tool will be sustainedstraight when operating upon sheet metal and the load or weight of such tool will be almost entirely upon the attachment, thereby relieving the operator of this load or weight when the tool is in use and being operated.

Another object of the invention is the provision of an attachment of this character, wherein the tool will be supported at several points and yieldably seated, yet will be held to the work for the successful operationof the tool, whereby on the working of said tool any irregularitiesin the surface of the work, such as kinks or bends therein, can be conveniently removed orerad'icated.

A further object of the invention is the provision of an attachment of this character wherein the in form so as to the fender tool is being operated for the straightening of sheet metal, such as automobile fenders, rad ators or other sheet metal parts, and a positive bearing or support will be afforded at the working end of the tool to relieve an operator from the weight of the tool when in use.

A stillfurther object of the invention is the provision of an attachment of this char acter which is extremely simple in construction, adaptable types of fender for mounting upon different tools, being more especially designed for use on a tool constituting the subject-matter of the above ident fied application, said attachment being thoroughly reliable and efficient in its purpose, strong, du'-.

rable, and inex install.v

pensive to manufacture and ussuEn tachment removed from the tool,

Figure 3 is a top plan view thereof,

Figure t is an enlarged vertical sectional View through the attachment showing the same mounted upon the tool,

Figure 5 is a front elevation of the tool with the attachment thereon and in position for operation upon a piece of work, and

Figure 6 is a top vplan view of a sligh modification of the attachment. 1

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the fender tool A constitutes the subject-matter of my aforesaid application; and mounted upon the frame 10 thereof, which is of substantially C-shape in contour, is the attachment forming the subject-matter ofthe present application and hereinafter fully described.

The attachment comprises a bracket B forming a yoke 11 with laterally extending opposed arms 12, the yoke being open at one side thereof and formed at this open side with upper and lower cars 13 and 14: through which are passed securing bolts 15, these being loosely passed through the upper and

lower ears

13 and 14 at one side of the opening in the yoke and threaded as at 16 in the upper and

lower ears

13 and 14 at the other side of said opening, so that the yoke 11 can be securely mounted upon the has the hammer 18 of the tool slidable therethrough to cooperate with the anvil 19 carried on the terminal of the lower tread of the frame 10, the anvil and the eye 17 being spaced apart to provide the entrance mouth of the frame 10.

The arms 12 at their outer end portions are formed with guides 20 which depend therefrom and have slidably fitted therein the stems 21- of bearing members and each stem at its lower end isfitted with a ballsocket head 22 having loosely fitted therein a bearing ball 23, while surrounding the stems 21 are coiled tensioning springs 24, these at their outer ends working against the heads 22, while at their inner ends they are seated against the arms 12'so that in this manner the bearing ball 23 will be yieldably supported. Engaged on the stems 21 are lock nuts 25, which bear against the arms 12 and limit the movement of the stems 21 in the guides 20 in one direction.

In Figure 6 there is shown a slight modification of the attachment wherein the yoke 11 has formed thereon a plurality of lateral extensions 26, these being fitted with the stems 27 carrying the bearing balls 23, and thus increased bearing is had in the use of this modified form of attachment. Therefore it is to be understood that the attachment may be provided with two or more of the bearing balls 23 accordingly to the nature of the work to be operated upon by the tool and the required bearing therefor.

In the use of the attachment when applied to the fender tool it will be observed that the bearing balls 23 contact with the piece of work at points removed from the hammer 18 of the tool, and the said attachment will sustain the hammer straight with relation to the work and it will carry the weight of the tool when the same is in operation.

As heretofore indicated the attachment B is particularly adaptable for the fender tool constituting the subject-matter of the above identified application, although the said attachment may be used with other types of fender tools or with tools having a reciprocatory hammer so that the latter will beheld straight when in operation and also the atv tachment will carry the load of the tool, or

in other words the weight thereof, thus relieving this from the operator of the tool.

It is also contemplated for the use of the attachment inconnection with any fender tool or other character of tool to which the device is applicable.

From the foregoing it is thought that the construction and manner of use of the attachment will be clearly understood and therefore a more extended explanation has been omitted.

What is claimed is 1. In a fender tool, a frame having'a hammer head, a reciprocating hammer in the head, a yoke detachably embracing the head and having laterally extending portions, stems slidably fitted in the laterally extending portions and having heads, bearing balls in said heads, and'means cooperating with the stems to yieldably support the same. 2.. In a fender tool a frame having a'hammer head, a reciprocating hammer in the head, a yoke detachably embracing the head and having laterally extending portions, stems slidably fitted in the laterally extending portions and having heads, bearing balls in said heads, means cooperating withthe stems to yieldably support the same, means for retaining the stems in the laterally extending portions, and guides on said portions for the stems.

In testimony whereof I aifix my signature.

NIILO PESOLA.
