Abstract
An impact power tool for use in supporting a tool tip for hand-working operations comprises a body presenting a bore and having first and second ends. A piston is received within the bore and is shiftable relative to the body, and an anvil is received within the bore at a first end of the body and is shiftable relative to the body along the longitudinal axis thereof. The anvil includes a recess extending in a direction substantially parallel with the axis of the bore so as to define a receptacle in the anvil adjacent the first end of the bore. A tool carrier block is provided which is shaped for receipt in the recess of the anvil and which includes a set screw for permitting attachment of the carrier block to a tool tip to be supported on the impact power tool. The carrier block is retained in the anvil by friction-fit engagement sufficient to retain the carrier block in the receptacle and to permit manual removal of the carrier block. Further, the axial position of the anvil relative to the bore is fixed by a transverse member interposed between the anvil and the body. The transverse member is rigidly supported on the anvil and is resiliently supported on the body so that the anvil is capable of limited axial movement relative to the body.
