ABSTRACT:
A pneumatically driven, impact-actuated auto body dent puller has a cylindrical slide weight coaxially movable along a slide shaft for impact against an abutment collar near one end thereof, the slide member being slidably enclosed within a tubular cylinder member having free fitting caps at each end and provided with a through opening near one end connected with a manually controlled valve for impressing a blast of pressurized air behind the slide weight when disposed at the forward end of the slide shaft for projecting the slide weight rearwardly against the abutment collar through the interposed rear end cap, thereby imposing a rearward striking force upon a sheet-metal screw secured at the forward end of the slide shaft which is removably receivable within a punched opening in the dented zone of an area of sheet metal to be repaired.
