Powered fastener driver with button cap delivery

A powered fastener driver comprising:

• a housing;
• a nosepiece extending from the housing;
• a driver blade movable within the nosepiece between a ready position and a driven position;
• a piston coupled to the driver blade for movement therewith;
• a driver cylinder within which the piston is movable;
• a storage chamber cylinder containing pressurized gas therein and in fluid communication with the driver cylinder;
• a lifting mechanism for moving the driver blade to the ready position;
• a motor coupled to the lifting mechanism, the motor driving the lifting mechanism;
• an onboard air compressor driven by the motor, wherein the onboard air compressor is driven while the lifting mechanism is driven;
• a fastener feed mechanism adjacent the nosepiece and in fluid communication with the onboard air compressor, wherein the fastener feed mechanism is actuated by compressed air from the onboard air compressor to feed fasteners into a fastener driving channel within the nosepiece;
• and
• a button cap feed mechanism adjacent the nosepiece and in fluid communication with the onboard air compressor, wherein the button cap feed mechanism is actuated by compressed air from the onboard air compressor to feed button caps into a position ahead of the fastener driving channel to allow fasteners to be driven therethrough during operation of the powered fastener driver.

A method of operating a powered fastener driver, the method comprising:

• energizing a motor;
• releasing a driver blade to drive a fastener into a workpiece;
• closing a solenoid valve coupled to an onboard air compressor;
• driving the onboard air compressor to provide compressed air into a feed system;
• actuating a primary feed mechanism with compressed air from the onboard air compressor;
• actuating a secondary feed mechanism with compressed air from the onboard air compressor;
• and
• returning a driver blade to a ready position.
