Classification: CPC B | IPC B

Claim 19:
20. A gas spring-powered fastener driver comprising:
a cylinder;
a moveable piston positioned within the cylinder;
a driver blade attached to the piston and movable therewith between a ready position and a driven position;
a lifter configured to move the driver blade from the driven position to the ready position;
a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter;
an input configured to provide torque to the transmission;
a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter,
wherein, in response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch,
wherein the transmission includes
a first bearing supporting a first portion of the output shaft for rotation,
a second bearing supporting a second portion of the output shaft for rotation, and
wherein the gas spring-powered fastener driver further comprises a housing including a cylinder support portion in which the cylinder is received and a transmission housing portion in which the first and second bearings are received to rotatably support the output shaft.
