<p>A reversible feeder shoe and door system for the magazine of a staple driving tool enabling set-up of the tool for right or left handed loading. The tool magazine comprises an elongated rail terminating at its forward end at the guide body of the tool. A row of staples is slidably mounted in straddling fashion on the rail. A feeder shoe, having a substantially symmetrical inverted U-shaped body, is slidably mounted on the rail in straddling fashion behind the row of staples. A resilient member constantly urges the feeder shoe forwardly so that the forwardmost staple of the row is located in the guide body drive track. The magazine may include a U-shaped elongated body in which the track is mounted. An elongated door is provided, swingable between an open position exposing the rail top and a closed position overlying the rail top to prevent inadvertent dislodgement of the staples from the rail. The feeder shoe has an operating handle extending laterally from one of its sides and a lug extending laterally from the other of its sides. When the shoe is shifted to its rearwardmost position on the rail by the operating handle, the lug engages a portion of the door, opening the door and releasibly locking the door in its open position, the feeder shoe being also releasibly locked in its rearwardmost position for loading. The feeder shoe is reversible on the rail so that its operating handle can be grasped by the left or right hand of the operator. The door is reversible, being mountable in parallel spaced relationship to either side of the rail.</p> |
