964,935. Guiding rope on to winch drums. A. G. HANSEN. July 4, 1962, No. 25691/62. Heading B8B. Apparatus for laying and guiding wire rope &c. on to a winch drum comprises sheaves 6, Fig. 1, on a support 5 which is reciprocated in a direction parallel to the drum axis by a screw spindle 3 which is rotated at variable speed dependent upon the rope diameter. The screw spindle 3 is driven step-by-step through a pair of one-way roller ratchets 9, 10 mounted within an oscillatable housing 8 and having inner members 14 alternately engaged by a ratchet tooth clutch member 16 keyed to the spindle 3. Movement of the clutch member 16 is made through a shifting fork 17 carried on a slide shaft 20 having end stops 23 engaged by the support 5 and operating to reverse the direction of rotation. Spring-loaded locking means 25 holds the shaft 20 in each shifted position. The housing 8 is oscillated with a variable stroke through an eccentric pin 33 engaged within a slot 34 of a two-armed lever 35 which is oscillated by a crank pin 38 engaged within a second slot of the lever 35 and mounted on a crank 39 of a continuously rotating drive shaft 40. The lever 35 is pivoted to a pin 36 which is adjustable in position through a screw and nut mechanism 41, 42 to vary the degree of oscillation.
