  • Patent number: 10625406
    Abstract: A fastener-driving tool including a housing, a driving device associated with the housing and including a driver blade, a biasing member and a coupler attached to the driver blade and the biasing member, and a compound gear rotatably attached to the housing and in engagement with the coupler, where the compound gear is configured to rotate between a first position and a second position. The compound gear is rotated to the first position to move and secure the biasing member in a biased position when the driver blade is in a pre-drive position, and upon actuation, the biasing member is released from the biased position and biases the compound gear to move to the second position thereby causing the driver blade to move to a driven position for driving a fastener.

  • Patent number: 8925780
    Abstract: A nailer includes a power source including a piston reciprocating within a cylinder; a driver blade secured to the piston for common movement relative to a nosepiece; a magazine connected to the nosepiece for feeding fasteners sequentially for being driven into a workpiece by the driver blade; a fastener delay mechanism operatively associated with the magazine and configured for engaging a subsequent fastener and delaying advancement of the second fastener to the nosepiece until the driver blade returns to the pre-firing position after driving a leading fastener; and wherein the delay mechanism includes an electromagnetic solenoid with a reciprocating plunger connected to a pivoting cam member such that extension of the plunger causes the pivoting cam member to pivot into a blocking position between the fasteners.
