Abstract
A magazine for a fastening tool drives one or more fasteners into a workpiece. The magazine generally includes an outer case and an inner rail movable relative to the outer case. The inner rail is extendable from the outer case to permit adding the one or more fasteners to the magazine. A bar extends between a front end and a rear end of the inner rail. A pusher bearing slidably receives the bar. A spring biases the pusher bearing toward the front end. A pusher block is coupled to the pusher bearing and disposed over the bar. The pusher block is operable to rock about the pusher bearing as the pusher block is sliding through the inner rail to urge the one or more fasteners toward the front end.

A magazine for a fastening tool that drives one or more fasteners into a workpiece, the magazine comprising:
- an outer case and an inner rail movable relative to said outer case, said inner rail extendable from said outer case to permit adding the one or more fasteners to the magazine;
- a bar that extends between a front end and a rear end of said inner rail;
- a pusher bearing that slidably receives said bar;
- a spring that biases said pusher bearing toward said front end;
- a pusher block coupled to said pusher bearing and disposed over said bar, said pusher block is operable to rock about said pusher bearing as said pusher block is sliding through said inner rail to urge the one or more fasteners toward said front end.
A magazine for providing one or more fasteners into a nosepiece of a fastening tool to drive the one or more fasteners into a workpiece, the magazine comprising:
- an outer case and an inner rail movable relative to said outer case, said outer case having a front end and a rear end, said front end connected to the nosepiece, said inner rail extendable from said outer case to permit adding of the one or more fasteners to the magazine;
- a pusher bearing connected to said inner rail, said pusher bearing defining a flat surface adjacent to a generally cylindrical surface;
- a spring that connects to said flat surface of said pusher bearing, said spring operable to urge said pusher bearing toward said front end;
- a pusher block coupled to said generally cylindrical surface of said pusher bearing, said arcuate surface of said pusher block permits said pusher to rock about said pusher bearing as said pusher block is sliding through said inner rail to urge the one or more fasteners toward said front end.

- an outer case and an inner rail movable relative to said outer case, said outer case having a front end and a rear end, said front end connected to the nosepiece, said inner rail extendable from said outer case to permit adding of the one or more fasteners to the magazine;
- a bar that extends between said front end and said rear end of said inner rail;
- a pusher bearing connected to said bar, said pusher bearing defining a flat surface adjacent to a generally cylindrical surface;
- a spring that connects to said flat surface of said pusher bearing, said spring operable to urge said pusher bearing toward said front end;
- a pusher block coupled to said generally cylindrical surface of said pusher bearing, said generally cylindrical surface of said pusher bearing permits said pusher block to rock about said pusher bearing as said pusher block is sliding through said inner rail to urge the one or more fasteners toward said front end.
