ABSTRACT:
A powered screw gun having a magazine for storage of screws. The housing of the gun is arranged to provide a broad, flat base which rests on the work piece receiving screws, and two arms or towers projecting perpendicularly from the flat base. A handle is slidably mounted on the two arms. When the handle is depressed, or moved towards the flat base, a screw driver blade moves in tandem therewith. A return spring returns the handle to the original position. A pneumatic shock absorber prevents excessively abrupt return of the handle. A motor located in a fixed location remote from the blade rotates the blade by a drive train which accommodates projection of the blade towards and away from the work piece. The bit of the blade is removable, and held in place magnetically. The switch for reversibly operating the motor is carried on the movable handle. Indicia indicates the position of the blade and a screw being driven, which screw is concealed within the housing.
