ATTORNEYS" Patented May 18, 1943 UNITED STATES PATENT ()FFICE 2,319,478 BODY AND FENDER PICKUP rOoL William E. Rybak, Cleveland, Ohio Application April '7, 1942; Serial No. 437,952

1 Claim.

This invention relates to tools, and more par ticularly to tools that are referred to in the trade as body and fender pick-up tools, the same being employed for the purpose of straightening out small inwardly projecting indentations or rotuberances that are left in fenders and bodies after the conclusion of the ordinary straightem ing operations to which these parts are subjected following injury thereto. Difiiculty has been encountered in accurately locating these small protuberances and in accurately positioning with reference thereto the straightening tools that have been used for the purpose of effecting their removal. I

The general purpose and object of my invention is to enable these inwardly projecting protuberances or high spots to'be easily located by the tool and also to enable the operating portion of the tool to be accurately positioned with reference to the said protuberances, whereby they may be conveniently hammered into alignment with the external surfaces from which they project.

A further and more limited object is to provide a tool of this character which is compact and economical of production and which will enable the straightening or hammering operations to be conveniently and efiiciently performed.

I accomplish the foregoing objects in and through the construction and arrangement of parts shown in the accompanying drawing wherein Fig. 1 represents a sectional side elevational view of a tool constructed in accordance with my invention; and Fig. 2 an end elevational view of the said tool.

The tool shown herein comprises generally a body member, in which the impact portion of the tool is mounted and guided for reciprocation and which body member may also provide a hand grip for the operator as well as a means for aligning a protuberance with the operating end of the impact device; it also includes a member to which power may be applied for driving the impact device; also a spring operatively interposed between the body member and the power receiving member for retracting the impact device after the latter has been driven against a protuberance.

Describing by reference characters the parts illustrated in the drawing, l0 denotes the body member, the same being preferably made of metal and of a size to render it capable of being conveniently grasped by the operator, the said body member having a chamber ll extending thereinto from the operating front end thereof,

there being an annular shoulder 12 extending inwardly from the rear end of the wall I l of said chamber. From the inner periphery of said shoulder a bore l3, of smaller diameter than the chamber l l, extends rearwardly through the said body member.

I4 denotes the enlarged operating head of an impact device, the said head preferably fitting snugly within the chamber II and being provided with a tapered conical front end [5 and with a shoulder I l at the base thereof adapted to engage the shoulder l2 when the head is seated within the chamber. The head M of the impact device is carried by an elongated shank l6 ofsaid device, said shank extending rearwardly through the guide bore 13, of which the chamber l l constitutes an enlarged extension, to a point remote from the body member Ill where it is connected to a power-receiving member H, a helical spring [8 being interposed between the body member I!) and the power receiving member H. Owing to the length of the body member and to the fact that the guide bore extends entirely throughout the same, the said bore provides an elongated bearing for the shank I 6 which insures the accurate centering of the conical end of the head M with respect to the outer and surrounding end .of the chamber II. The shank It may be connected to the power receiving member I! by being threaded thereinto, as shown. The operating end of the body member I0 is preferably provided with a plane annular surface l9 surrounding the chamber II and extending inwardly to the outlet therefrom and at right angles to the axis of the bore of the body member. The front operating end of the body If) is rearwardly tapered from the periphery of the said annular surface to the junction of such front operating end with the side of the body member.

The operating head [4, including the tapered or conical end I5, is of such length that, when seated within the bore H, the tip of said head will be substantially flush with the end of the bore 1 l and the plane surface l9.

With the parts constructed and arranged as described, the operation can be readily understood. The operator, grasping the body member with one hand, moves it along the inner surface of the body or fender, and a protuberance projecting from such surface will be received within the outer, front end of the chamber H and will be contacted by the end l5 of the head. The op erator then holds the body member with one hand and, by striking the power receiving memher I! with a hammer, can readily eliminate a protuberance that has been thus centered by the operating end of the tool. The spring [8 oper ates to return the head and shank to the positions shown in Fig. 1 after the element I! has been struck by the hammer. It frequently happens that the protuberances are so located as to prevent the portion of the operating end of the body member which surrounds the outer end of the chamber ll from engaging the entire surface of the metal surrounding such protuberances when the latter project into said chamber. Due to the tapered shape of the operating end of the body member, there can be a considerable tilting of the body member without bringing the line of junction between the said operating end and the side of the body member into contact with the metal which is being operated upon; this will enable the operator to remove such pro; tuberances without cutting or producing a dent in the metal adjacent to the latter, as might occur if the edge formed at the junction of the side of the body member and the operating end of the tool should be brought into contact with this portion of the metal. Furthermore, when operating upon a protuberance which can be received Within the outer end of the chamber, with the annular surface I 9 in engagement with the metal surrounding the protuberance, it is possible to strike a sharp blow upon the impact memher without danger of rupturing the metal surrounding the protuberance.

It is within the purview of my invention to use my tool with other power means, such as can be supplied by the pneumatic hammer. For this purpose, an extension 20 of the shank It may be threaded into the member ll, as shown in dot-and-dash lines in Fig. 2, said extension being of such dimensions as to adapt the same to be inserted readily into the bore or chuck of a pneumatic hammer and to enable the member I! to constitute an abutment for engagement with the end of the hammer, whereby the end of the shank extension 20 will be properly positioned in said bore for impact by the piston of g aid am r- It will be evident that a tool made in accordance with my invention is particularly adapted for the purpose for which it is designed and that it is simple in construction, economical of production, and convenient of operation.

Having thus described my invention, what I claim is:

A tool for removing indentations or protuberances from fenders and bodies of vehicles, the same comprising an elongated body member of a size to be, conveniently grasped by the operator and provided with a bore extending longitudinally therethrough, the said bore being enlarged to provide a chamber extending through the front, operating end of the said body member, with an annular shoulder provided between the said chamber and the remainder of said bore, an impact device comprising an elongated shank having at one end thereof a head adapted to be received within said chamber and having at its inner, rear end a radially extending shoulder adapted to engage the first mentioned shoulder, the said liead'having a tapered operating front end and the head being of such length that the tapered operating end thereof is normally located within said chamber and substantially in a plane extending transversely of the. outer end of said chamber when the shoulder of said head is in engagement with the said annular shoulder, the body of the shank being mounted within and guided by said bore and extending rearwardly beyond said body member, a power receivingmember with which the rear end of said shank is connected, a helical spring surrounding said shank between the body member and the power receiving member, the front end of said body having a plane-annular surface extending outwardly at right angles to the axis thereof from the periphery of the outlet from said chamher and surrounding said outlet and the said operating front endof said body member being outwardly and rearwardly tapered from the periphery of said annular surface to the junction of the operating end of said body member with the side thereof.
