Abstract:
1. A fastener driving device comprising: a portable frame constructed and arranged to be manually handled, said frame defining a fastener driving track, a magazine assembly constructed and arranged to feed successive fasteners from a supply of fasteners along a feed track into said drive track, a fastener driving element mounted in said drive track, a power system constructed and arranged to move said fastener driving element through successive operating cycles each of which includes a drive stroke operable to drive a leading fastener fed along said feed track into said drive track outwardly into a workpiece and a return stroke, an actuating assembly constructed and arranged to actuate said power system to move through an operating cycle, including an input actuator movable from an inoperative position into an operative position to actuate said power system, a contact trip assembly mounted for movement from an inoperative position into an operative position in response to the engagement of the tool with a workpiece, a trigger assembly operatively disposed between said contact trip assembly and said actuating assembly including: a trigger member pivoted to said frame for movement between inoperative and operative positions, an actuating member having a connection with said trigger member and a free end cooperable with an output actuator of said contact trip assembly constructed and arranged to enable a portion of said actuating member to move the input actuator of said actuating assembly into its operative position in response to movement of said contact trip assembly and said trigger member into the operative positions thereof, the connection of said actuating member with respect to said trigger member being constructed and arranged to accommodate movement of said actuating member with respect to said trigger member between an automatic mode selecting mechanism including a mode selecting member having a connection with said actuating member constructed and arranged to make said mode selecting member
