Abstract

13,085. Veritys, Ltd., and Worsley, F. S. June 6. Winches.-Self-sustaining hand-winches, particularly applicable for raising and lowering arc lamps, are constructed so that the self-sustaining mechanism may be released, when it is necessary to lower the load, by a longitudinal movement of the rope drum. The drum d has at each end a flange, one of which engages, by a ratchet tooth or teeth, with the cover b of a fixed casing a forming a support for the winch. A spring e, enclosed within the hollow drum, normally presses the ratchet teeth into engagement. During the raising of the load, the teeth ride over each other, and, when it is required to lower, the drum is pressed to the left, thsreby disengaging the teeth. The ratchet clutch may be replaced by one with rounded teeth or an ordinary dog clutch. If the drum axis is vertical, the spring is not required, the weight of the drum keeping the teeth in engagement.
