Abstract
20,607. Winzer, C. B. Sept. 10. Screw-and-nut mechanism. - A rod a, Figs. 1 and 3, with a right and left handed thread thereon is reciprocated by a handle l and gives motion through a hollow shaft e to the propeller shaft h which carries a fly-wheel f. Two disks d in casings e, Fig. 3, are free on the rod a, have opposite ratchet faces c, c<1>, and can be fixed by screws d<2> relatively to the casings. Short hollow tubes b, b<1> free in the casings e' each engage a thread on the rod a and have side ratchet teeth. For forward running, one of the disks d is secured to the casing, and for reversing, the other disk is fixed. In a modification, instead of separate setscrews for the disks, a spring-controlled pin on an arm can be slipped through holes in the casing to take into indentations on either disk.
