ABSTRACT:
A recoil windlass is provided with a casing, a reel wound with a wire having a hook end for suspending a hand tool, a hub member nonrotatably and axially mounted in the casing and formed with an internally threaded passage and a recoil spring mounted on the hub member with an inner end anchored to the hub member and an outer end anchored to the reel member so as to retract the wire into a coiled position in the casing under the bias of the recoil spring when the wire is released from an extended position. A nut is threaded into the passage with a leading end frictionally contacting a shaft means axially movable during rotation of the reel member through a thread engagement with the passage of the hub member.
