ABSTRACT:
A saw blade clamping arrangement particularly for power reciprocating saws and similar tools having a reciprocating shaft connected to a cutting member includes a locking member and a locating pin which cooperates to prevent inadvertent removal of the saw blade. The saw blade clamping arrangement further includes a support member carried by the drive shaft for movement therewith. The support member at least partially defines a longitudinal slot for receiving the saw blade. The locating pin extends into the longitudinal slot and is adapted for partial insertion into the aperture from a first side of the saw blade. The locking member, which in the preferred embodiment is a spherical bearing, is operative for selectively engaging the saw blade with the drive shaft. The locking member is movable to a locking position in which the locking member is partially inserted into the aperture from a second side of the saw blade.
