Patent ID: 7017385

Claim:
Door skin hammer apparatus adapted for activation by a conventional pneumatic door hammer comprising: a frame supporting an axially slidable striking hammer having a head adapted to mate with an anvil equipped with a resilient bed member; said anvil being mounted for axial movement within a hollow support member between spatially separated latching members; means for selectively mounting the striking hammer in one of two operative positions as crimping of a vehicle door skin edge progresses from an angle of approximately 90° to the generally planar shape of the door skin to a finished fully-folded shape encasing the door edge; said anvil and said striking head being mountable on opposite sides of the vehicle door skin edge so as to fold said door skin edge about said door edge; the first position being established at a selected angle between the approximately ninety-degree initial configuration of the door skin edge and 90° to the plane of the door skin; and the second position being established at an angle essentially perpendicular to the plane of the door for achieving complete crimping of the door skin to the door frame.
