ABSTRACT:
A clamping bench dog that provides a simple, economical clamp that may typically be used with conventional round dogs but is also usable with square or rectangular dogs, other clamping dogs and the hold-down described in U.S. Pat. No. 5,275,391. A section of round metal rod provides a clamp body or post that fits into a bench dog hole. A second, threaded rod passes through a threaded hole near the upper end of the post at an angle of approximately eighty-seven degrees (87.degree.) to the axis of the post. A rotatable foot is attached to one end of the threaded rod and can tilt up to about three degrees (3.degree.). A handle, knob or tangent on the other end of the threaded rod is utilized to rotate it, and a wire spring journaled in a longitudinal groove on the post assures that the post will remain fixed in bench top dog holes by pressing against the wall of the hole to increase the friction between the post and wall.
