Abstract
A coping saw of the type having a generally U-shaped frame with a pair of spaced legs has mounted thereon adjacent the free ends of the legs elongated anchor bolts with axially extending slots at their opposed ends to receive the end portions of the saw blade. Each of the anchor bolts has a generally L-shaped notch intersecting the axial slot and providing a sloping leg portion which extends from the periphery towards the opposite leg of the frame and an axial leg portion which extends from the inner end of the sloping leg portion towards the adjacent leg. The transversely extending pins on the saw blade seat in the sloping leg portions of the notches until deflection of the frame occurs. When such deflection occurs, the pins are cammed into the axial leg portions of the notches.
