Abstract: An automatic chain lock allows successive pulls on a vehicle on a straightening apparatus without manipulation of the chain lock between actuations of the fluid cylinder. A pair of gates provides a ratchet arrangement for the chain, the lower gate holding the chain while the lower gate is moved down to pull the chain and cause the chain to ratchet through the upper gate; and, when the movement reaches its end, the upper gate secures the chain while the chain ratchets through the lower gate. The procedure is then repeated, the lower gate again moving down to make another pull on the vehicle. Each gate has a pair of flanges that pivot down, but are held against pivoting up. The two gates are arranged with respect to each other so that each will engage a link of the chain at the appropriate time in the cycle.

Abstract: Support structure for carrying a vehicle body comprises a pair of spaced apart frames positioned about a front and rear end of the vehicle body. Each frame has an octagon shape formed by joined elongated members. A cross bar assembly of each frame includes a pair of sleeve supports positioned on side members of the frame body and a center member pivotally carried by the sleeve supports. Latching mechanisms at ends of the cross bar assembly limit the degree of center member rotation with respect to the frame body. During use the frames are positioned horizontally so that bottom sections may be slid under respective slightly raised ends of the vehicle body. Mounts on each cross bar assembly then are attached to mounting structure of the vehicle. Next, a top member of one frame is lifted upward which rotates the frame body and lifts that end of the vehicle body. When vertical, its latching mechanisms activate to inhibit further frame movement. Bracing carried by the frame then is attached to the vehicle body.

Abstract: The sacrificial tube shock attenuation device services as a deformable energy absorbing system designed to be employed between a bumper receiving a potentially destructive force and a payload which is to be protected from the force. The device is composed of a tube assembly running through and aligning apertures of a maul, or series of mauls, which is (are) attached to the bumper and the apertures of a pair of stators, or multiple pairs of stators, that each maul is situated between.

Abstract: A battery powered dent puller for re-contouring sheet metal having a dent is disclosed. A direct current welding electrode mounted on a handle allows the user to attach the electrode to an indentation in sheet metal with a very brief surge of 12 volt direct current. The welding current is regulated by means of a switch mounted on the handle which controls a relay through which the current travels. Once the electrode is attached on the sheet metal, the user may pull with considerable force in a direction that is generally in-line with the electrode. The force of the user pulling on the sheet metal tends to alter the contour of the metal, thus pulling out the indentation. To disengage the electrode from the sheet metal, the user twists the electrode, which breaks the weld. The battery power supply allows portability, increases safety, and tends to reduce assembly costs.
