Abstract: An example hammer tacker includes a contact face for contacting a material and a firing mechanism adjacent the contact face. The firing mechanism drives a staple into the material when the contact face is brought into contact with the material. A curved staple guide extends from adjacent the contact face.

Abstract: A staple gun tacker includes a wire guide mechanism in its forward end which includes a wire guide plate having a recessed lower end for engaging a wire when the plate is in an extended position and a rotatable cam for moving the plate between extended and retracted positions which includes a circular slot formed therein having one end thereof located closer to the axis of rotation of the cam then the other receiving and engaged with a projection on the cam plate so that rotation of the cam is translated into linear movement of the wire guide plate.

Abstract: A continuous cap feed mechanism for use with fastener driving device includes a housing for receiving a coiled strip of interconnected caps removably mounted the fastener driving device. The housing includes a passageway for guiding the strip of caps from the coil to a position beneath a fastener to be driven by the fastener driving device and an advancing mechanism for moving the leading cap on said strip from the passage to the position beneath the fastener to be driven after the fastener driving device drives a prior fastener into a cap and as it is moved away from the previously driven fastener. The advancing mechanism includes a driver movably mounted in the housing for movement between an extended and retracted position adjacent the location on the fastener driving device at which the fastener driving device drives fasteners.

Abstract: A fastener gun includes a housing having a plunger and a power spring for driving a fastener into a workpiece, and a trigger arm pivotally attached to the housing at a trigger pivot. One end of the trigger arm lifts the plunger to bias the power spring when the trigger arm pivots in a first direction toward the housing. A member contacting the trigger arm is provided that moves away from the trigger pivot as the handle moves toward the housing, so that force is applied at different locations on the trigger arm when the handle is squeezed, increasing the mechanical advantage of using the fastener gun.

The trigger arm lifts the plunger to bias the power spring when the trigger arm pivots in a first direction. The example fastener gun also includes a handle extending upwardly from the housing and pivotally attached to the housing at a handle pivot, and a roller for pivoting trigger arm in the first direction when the handle moves toward the housing. The roller moves away from the trigger pivot when the handle moves toward the housing.

Abstract: A forward acting stapler includes a unique linkage for driving a firing lever. The linkage includes two links that are each connected to the trigger lever by a roller. The roller is movable within a spot in the trigger lever. As the handle is driven, the two links cause the triggering level to pivot. As the trigger lever pivots it lifts a plunger against a spring force. At some point, the trigger portion releases the plunger allowing the plunger to be returned by the spring force by a staple.
