Abstract
A pulling clamp which can engage an automotive frame member at two points. The pulling clamp includes two elongated bow shaped members (12, 14) each of which is provided with at least one elongated slot (18) for the reception of a bolt (66) which is passed through suitable apertures in the frame member (56) to be pulled the bolt being held in place by a nut (68). The bow shaped members are spread apart by a threaded spreading member (34) to firmly clamp opposed side walls of the frame member between the head of the bolt, the nut, and the outer surfaces (20) of the pulling clamp. In one embodiment a second elongated slot (90) is provided inwardly of the first elongated slot (28) so that box sections of smaller width may be engaged by passing a bolt through a second set of elongated slots. In another embodiment threaded apertures (30, 42) are disposed inwardly of the elongated slots (28), which threaded apertures may receive additional gripping means (72).
