The cnd of thc pintlc which projects through tho ratchot wheel '7 is extended beyond tl-router side ol the adjaccnt car 3 of thc lent], and said cxtondml cud is threaded to rccoivc a thumb nut, 13, which is screwcd thcrnon and into cngagcmcnt with the ad eu-cut sidc ol thc car I), thus oomprmsing said car and clamping thc washcr N into greater or lcss frictional crwgcmcnt with tho ratchtt wht'ol, 7, which fort-ca thc samc into cngt-rzrcm-"nt with the shouldcr on tho pintlc 5, thcrclrv rctardiug' thc movcincnt ol' the ratchet vvhccl, and tho loaf 2 of thc hin gc.
