Abstract:

An electrically operated fastener driving device comprising a housing structure providing a manually engageable handle for engaging a user to portably operate the device, a front wall disposed in vertically extending relation forwardly and below the handle and a vertically extending fastener drive track disposed closely adjacent the front wall. A solenoid is carried by the housing structure forwardly of the handle and rearwardly and above the drive track and includes an elongated plunger having a longitudinal axis inclined with respect to the vertical. A cam and cam track mechanism is disposed between the upper end portion of the fastener driving element slidable in the drive track and the lower end portion of the plunger for causing a downward stroke of the plunger in response to the energization of the solenoid to effect a drive stroke of the fastener driving element. A torsional coil spring is provided in the housing structure for effecting a return stroke of the fastener driving element and plunger in response to the deenergization of the solenoid.
