Abstract
A level wind mechanism includes a first screw and a second screw extending through a block. A shoe is disposed within the block between the first screw and the second screw. The shoe includes a first follower for engaging with and being driven by a thread of the first screw and a second follower for engaging with and being driven by a thread of the second screw. Each thread includes cams at the terminal ends of the thread for causing the shoe to disengage from that thread and to shift to engaging the other thread. In this way, the first screw and the second screw cause the shoe, and thus the block, to translate relative to the first screw and the second screw.
