Abstract
The present invention is a power-operated screwdriving device configured to be used with a rotary power source and a supply of screws releasably mounted on a severable collation. The screwdriving device comprises a housing structure constructed and arranged to be engaged with the rotary power source. Structure defines a drive track constructed and arranged to receive a lead screw releasably mounted on the severable collation. A rotatable screw engaging bit member is constructed and arranged to be operatively connected with the rotary power source such that the rotary power source can rotate the screw engaging bit member. The screw engaging bit member is engageable with the lead screw and movable relative to the drive track such that rotation of the screw engaging bit member and relative movement between the screw engaging bit member and the drive track separates the lead screw from the severable collation and drives the lead screw from the drive track into a workpiece during a screwdriving operation. A feeding assembly is constructed and arranged to move the supply of screws and the severable collation relative to the drive track such that a subsequent lead screw is moved into the …
