ABSTRACT:
An auto body clamp having first and second plates attachable to a pulling device and selectively drawn together at a metal-gripping jaw arrangement by a clamp which pivots the plates about a fulcrum formed by a ball disposed in recesses provided in the plates. The jaw arrangement includes teeth disposed in apertures provided in the plates, with the teeth of each plate being offset from the teeth of the other plate. Each of the teeth is arranged in a respective aperture for movement within the aperture relative to the respective plate. Setscrews are arranged in countersunk portions provided in the apertures for permitting variation in the amount a given tooth will extend beyond the respective plate when the tooth is applying pressure to a portion of an automobile body, and the like. A tongue connected to the ball disposed in the recesss of the plates advantageously forms the connection of the plates to a suitable pulling device.
