Abstract

A miter gage having an adjustable workpiece clamp. The miter gage is of the type having a bar shaped to slidably engage a guideway of a tool work table, a protractor mounted on the bar and a grip mounted on the protractor. The clamping device includes a lock guide having a base adapted to be attached to the grip, a longitudinally-extending, vertical opening and a pair of opposing side walls; a U-shaped lock clamp having a sidewardly-opening channel receiving the lock guide and including a vertical bore positioned in registry with the lock guide opening, a lock rod extending vertically through the bore and opening and a lock knob having a stud which is threaded through the side of the lock clamp to bear against an adjacent sidewall of the lock guide. Displacement of the threaded stud relative to the lock clamp urges the lock guide sidewardly out of the channel and causes the lock rod to be urged against the lock guide, thereby preventing its relative movement. By selectively loosening or tightening the threaded stud against the sidewall of the lock guide, the lock rod may be alternately locked in position or released for vertical movement to an appropriate height above the associated work table to accommodate a particular workpiece.
