FENDER AND BODY STRAIGHTENING TOOL Filed Feb. 20, 1932 44 14. ATTORNEY.

1 Claim.
My invention has reference to a fender and body straightening tool, and contains some improvements on a similar tool for which an application for Letters Patent of the United States was filed by myself on Feb. 5, 1931, Serial No. 513,648, now issued as Patent No. 1,893,196, dated Jan. 3, 1933. In the tool shown in said former application the operation was limited to a movement of the straightening rolls in a direction laterally to the plane of the frame, whereas it has been discovered that there is frequently an advantage in being able to operate said rolls in a direction at right angles thereto, or in line with the frame. The chief purpose of the present invention consists in the provision of cer tain adjustment features which make it possible to operate the tool in either manner, and thereby I greatly increase its usefulness.
In the drawing accompanying this specification,
Fig. 1 shows the invention in side elevation, in position for its common use.
Fig. 2 is an end view thereof.
Fig. 3 is a detail of the end of the arm 1, in plan.
Fig. 4 shows the upper face of the frame 22.
Fig. 5 shows the lower face-of the head 20, broken away.
The frame of the tool consists of a pair of spaced arms 1 and 2, the latter of which has bifurcated arms 4, between which is held an angular extension 3 of the arm 1, said parts being perforated to receive a bolt 5, holdinplace by a nut 6 on its threaded end. By this connection the arms 1 and 2 are capable of a limited hinge action with relation to each other, whereby the free ends of the arms can be separated for the purpose of positioning the tool on a fender. Said arms may be held from such movement by means of a bolt '7 passing through other openings in the arms 4 and extension 3, and provided on its threaded end with a thumbturn 8. When the bolt 7 is in position the frame is practically rigid.
At the free end of the arm 1 is a cross-head 10, provided in its ends. with a pair of holes 11, adapted to receive a pair of rods 12, and at right angles with the line of a similar pair of holes 13, in which said rods are normally positioned, as shown in Fig. 1. The rods 12 are united by a bar 14, with which is engaged the inner end of a screw 15, operative in a threaded opening in the end of the arm 1. In the head of the screw is a hand-bar 16 for convenience in rotating the screw. The inner ends of the provided with bearings to receive the ends of a shaft 23, on which is mounted a roller 24. On the threaded end of the bolt 21 is a thumbturn 25 for holding the frame 22 in place. The frame 22 includes a circular plate 26, on the face of which is a V-shaped rib 27, adapted for alternative engagement with a pair of crosschannels 28 and 29 in the inner face of the head 20. By tightening the thumb-nut 25 the frame 22 and roller 24 can be held in adjusted positions.
The rollers 13 and 24 are positioned in opposition to each other, as shown in Fig. 1, and by first removing the bolt 7 and opening the arms of the frame the rollers 18 and 24 can be positioned on opposite sides of a piece of sheet metal for straightening'the same. By the action of the screw 15 the roller 18 can be adjusted with referenoe to the roller 24, so as to cause a close cooperation thereof in rolling out a bend in an automobile fender. This work is generally accomplished with the rollers in the position as shown in Fig. 1, and by grasping the upper arm of the frame with one hand and the other arm with the other hand and moving the rollers back and forth in a direction at right angles with the plane of the frame. In some cases, however, it is found to be desirable to operate the frame at right angles with said first-named movement,
with the rollers in the position as shown in Fig.
2, and to accomplish this the position of the roller 24 can be adjusted by loosening the thumbscrew 25 until the rib 27 is free from the channel 28. The frame is then turned at right angles with its former position and the rib reengaged with the channel. 29, in which it is held by tightening the nut 25. In a somewhat similar manner the screw 15 is operated to release the rods 12, which are then turned and reengaged in the openings 11 of the crosshead, with ing and terminal for holding said mounting in adjustable positions, at right angles with each other, a mounting having a pivotal connection with the other of said terminals, guides for said lastnamed mounting engageable with guiding means in the terminal, said guiding means permitting of an adjustment of said mounting to conform to the position of the first-named mounting, and. means for adjustment of the last-named mounting to or from the terminal with which it is connected.
