ABSTRACT:
A gauge member has an abutment edge at one end for engaging a workpiece in establishing a depth of cut and is mounted in a holder on an adjustable working member. A spring urges the gauge laterally of the frame to position the abutment edge toward a workpiece but allows the gauge to be swung out of the way by a carriage as the latter passes by. The gauge is pivotally jointed intermediate its ends whereby to be capable of partially folding and releasing the abutment edge from a stuck position in a workpiece. A spring connects the jointed portions of the gauge and such spring in combination with the pivot for the joint maintains the sections in longitudinal alignment but allows the sections to partially fold and allow the abutment edge to free itself from the wood.
