Abstract: A fastener driving tool that includes a lift mechanism for moving the driver from a driven position to a ready position. In one embodiment, the lift mechanism is mounted to a movable pivot arm, and the pivot arm is slightly rotated to allow the driver to drive a fastener; when the driver is to be lifted in a return stroke, the lifter subassembly is moved back into engagement with the driver, and multiple lifter pins contact protrusions in the driver to lift the driver from the driven position to the ready position. In another embodiment, the pivotable lifter floats along the driver, and “releases” from contact only to prevent a jam or otherwise undesirable operating condition involving the driver; otherwise, the lifter remains nested in the tool's guide body during all operating states. A solenoid-operated latch also is provided to prevent the driver from moving downward (for driving a fastener).

Abstract: A mechanical timer mechanism can include a driven gear mounted to a rotary damper and a drive gear operably coupled to the driven gear. In bump mode, movement of a trigger to its firing position can initially move the drive gear into its wind-up position. Thereafter, a contact trip can move the drive gear to its wind-up position and an actuator of the trigger to its firing position each time the contact trip is activated, unless the timing mechanism has timed out between firings. In sequential mode, the drive gear can be moved into a timer lock-out position which holds the contact trip in a bypass position in which the contact trip will not engage the actuator of the trigger unless the trigger is moved to its firing position prior to activation of the contact trip.
