Abstract

A pitch bar self-adjusting clamp including a fixture having a handle and an opposing stationary jaw, a co-acting jaw pivoted to the fixture, a lever pivoted to the co-acting jaw, a guide bar pivotally coupled to the handle proximate the stationary jaw and movably coupled to the handle, and a toggle assembly coupled between the lever and the guide bar. The toggle assembly includes a locking element, a link pivoted to the lever, and a cam pivoted to the link and to the locking element. The cam is movable between a first condition permitting the locking element to reciprocate along the guide bar and a second condition bearing against the guide bar and canting the locking element into frictional engagement against the guide. An adjustment mechanism is coupled to the proximal end of the guide bar for movement between a low pitch position and a high pitch position.
