ABSTRACT:
A portable winch incorporating at one end a mechanism for providing its suspension from a stabilized support, said frame member having a cable winding drum provided therein, and a handle lever operatively associated with the drum and disposing a ratchet pawl for engagement with the ratchet wheel of the drum, in order to provide for a winding of the cable upon the drum, for lifting or supporting of a load, or for providing its gradual release therefrom. The ratchet pawl of the handle lever capable of manipulating into two positions, one providing for its permanent engagement with the ratchet wheel teeth, or in the alternative, through a maneuvering of its supporting spring, can be shifted out of engagement with the ratchet wheel teeth. A stop pawl operatively associates with the frame member and normally in engagement with the ratchet wheel, to maintain it in its wound position during manipulation of the handle lever. The stop pawl capable of being released from such engagement through pressure exerted upon its integral stem, to provide for a rapid unwinding of the drum wound cable, and its supported load, or through an upward exertion of the handle lever to its fullest extent, its ratchet pawl engages with and biases against a release cam, to force a temporary release of the stop pawl from the ratchet wheel, to provide for an incremental unwinding of the cable from its drum, through repeat movements of the handle lever and its ratchet pawl against the release cam of the stop pawl for this portable winch.
