Abstract
A magazine assembly for a fastener driving tool has an elongated fastener carrier defining a fastener feed path. The carrier is pivotally mounted about an axis parallel to the fastener feed path for movement between an operative, refill and an unjam position. In the operative position, the elongated carrier is latched by a latch assembly disposed in the forward portion of the tool. A pusher advances the fasteners forward to a nosepiece assembly. In one embodiment, retraction of the pusher releases the latch allowing the elongated carrier to pivot about an axis parallel to the fastener feed path under the influence of a spring to the refill position. In an alternate embodiment, the latch assembly is provided at the rear of the tool and is not interlocked with the pusher. A nosepiece assembly, secured to the forward end of the tool, defines a fastener drive track for guiding fasteners driven into a workpiece. The nosepiece assembly includes a front nosepiece and a rear nosepiece pivotably connected together to allow freeing of jammed fasteners. The front and rear nosepieces are provided with interlocking portions to prevent separation of the drive track during operation.
