ABSTRACT:
A portable winch unit of the ratchet type utilizing a ratchet dog mounted upon a hand lever for rotating the winch drum ratchet wheel wherein the ratchet dog is pivotally mounted upon the hand lever for pivoting between ratchet wheel engaging and ratchet wheel clearing positions. The dog includes an elongated slot receiving the end of a tension spring and a pivoted spring shifter plate mounted adjacent the dog shifts the spring end within the dog slot between two operative positions. The other end of the spring is anchored to the hand lever, and the orientation between the anchored spring end, the spring end within the ratchet dog slot, and the dog pivot axis is such that pivoting of the spring end within the slot by the spring shifter between the operative positions thereof produces a biasing force on the dog pivoting the same between ratchet wheel engaging and clearing positions.
