Abstract
1346434 Winding gear I R VERSOY and W J KRESKE 1 April 1971 8471/71 Heading B8B [Also in Division F2] A winch 10 for controlling the position of boat sails has at one end a one-way clutch 44 to allow rotation in one direction, and at the other end a one-way brake 42 to prevent reverse rotation of the winch drum 38. As shown, the clutch and brake are of the jamming roller type, the brake rollers 46 acting between a fixed spindle 12 and the drum, and the clutch rollers 72 acting between the drum and a sleeve 24 fast with a knob 28 having a slot 30 for insertion of a driving lever, and retained axially on the spindle by a screw 34. Again, Figs. 4 and 5 (not shown), the clutch and brake are of the sprag type. In Figs. 6 and 7 (not shown), the jamming clutch rollers again act between the drum (108) and a sleeve (126) fast with a knob (122) retained axially on the fixed spindle (142) by a spring washer (152) on the spindle. The spindle is retained in a fixed base (96) by a threaded end portion (146). Drain holes (140) and (155) are provided through the drum and knob. Again, Fig. 8 (not shown), the clutch and brakes are of'the helical spring type wrapping around axial extensions (180), (182) of an inwardly directed flange (184) on the drum.
