Abstract

A stand-up fastener driving tool including a rotary driver having a rotatable shaft with a fastener driving member disposed on a distal end thereof and disposed within telescoping upper and lower tubes, wherein the lower tube has a nose-piece with an opening for retaining a fastener therein. The fastener driving member is extendable toward and away from the nose-piece upon contraction and extension of the lower and upper tubes. A plurality of fasteners are retained side by side in a magazine of the tool, and are individually releasable therefrom upon contraction and extension of the upper and lower tubes. A feed tube connects the magazine to the nose-piece, and includes a magnetized wall portion for capturing and retaining fasteners fed from the magazine. A plunger actuatably coupled to the upper tube and movable relative to the feed tube releases the fastener retained along the magnetized wall portion of the feed tube as the lower and upper tubes are contracted, wherein another fastener is released from the magazine toward the feed tube as the lower and upper tubes are extended.
