Blade holder for saber saw

Claim 1

A holder for a saber saw blade of the type having a pair of opposed side marginal edges and a notch in one of the side marginal edges near the rear end of the blade comprising: a tubular support having an open end; a blade-mounting member inserted in the open end of the support and having a blade-receiving slot extending thereinto, the inner end of the member presenting a blade-engaging face and the side of the member having a recess communicating with the slot, said support having a hole communicating with the recess; means securing the member to the support; a ball movable partially into the hole, the recess and the slot; means including a pair of adjacent, interconnected cam elements rotatably mounted on the support for caging said ball so that the ball can move partially into and out of the notch of said saber saw blade when the blade is in said slot and as the ball extends at least partially through the hole and the recess, each element having a beveled, inner peripheral face, the beveled faces being adjacent to each other to form a cam surface engagable with the ball to force the latter partially into said notch when said elements have been rotated in one direction on said support, said elements being rotatable on said support in the opposite direction to cause the cam surface to be positioned to allow movement of the ball away from the slot and thereby to permit the blade to be inserted into and removed from the slot; and means coupled with the elements for biasing the same in said one direction.
