ABSTRACT:
The improved adjustment mechanism for work clamping includes a support member which is arranged for attachment to a supporting arm. The support member has a plurality of serrations which are regularlhy spaced across a generally planar support face formed on the support member. A clamping member is arranged for attachment to a locator block and includes a plurality of serrations regularly spaced across a generally planar clamp face. The clamping member is adjustably movable with respect to the support member. A tension member such as a bolt maintains the serrations of the support face and the clamp face in fixed positional engagement with one another when the mechanism is used for work clamping. The tension member is releasable for permitting adjustment of the position of the clamping member relative to that of the support member.
