Abstract
499,148. Winches. SLINGSBY & CO., Ltd W., SLINGSBY, W., and SLINGSBY, T. J. L. July 17, 1937, No. 19828. [Class 78 (v)] A winding-drum 3 is freely mounted on a shaft 4 journalled in a casing, and is furnished with a lateral ledge 3a which engages a side of a rectangular nut 2 riding on a screw-thread 4a on the shaft 4. The shaft 4 carries a frictiondisc 7 which bears against a ratchet-wheel 8 loosely fitted on the shaft 4 and engaged by a spring-pressed pawl on the casing. Rotation of the shaft 4 by a handle in the winding- on direction first brings the nut 2 against the drum along the thread 4a till the nut, drum, ratchet-wheel 8 and disc 7 form one unit through friction, and the winding-on then takes place with the pawl riding over the teeth. When the handle is stopped, the load is sustained by the pawl, but should the handle be reversed the nut 2 will leave the drum and, by removing the frictional hold on same, will allow the load to fall with the drum running freely. Specification 407,415 is referred to.
