Abstract: 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.

Abstract: A latch assembly to lock in closed position the front gate of the guide body of an industrial fastener driving tool of the type wherein the guide body and the front gate (in closed position) define a part of a drive track for the tool driver and fasteners. The gate has a first free end and a second end pivotally affixed by a pivot pin to the guide body and is swingable between a closed position against the guide body and an open position. The latch comprises a leaf spring overlying the gate and having a first free end and a second end pivotally affixed to the guide by the same pivot pin as the gate. The leaf spring has first and second angularly related portions so as to bow outwardly of the gate. A latch pin is mounted transversely on the leaf spring along the juncture of its first and second portions with the ends of the latch pin extending beyond the leaf spring.
