Abstract: A cable drive device of an adjustment system of a motor vehicle has an actuating drive and a cable drive housing in which a cable drum that is rotatably coupled to the actuating drive and has a traction cable wound thereon is received. The cable drum, for receiving a cable nipple fastened to the traction cable, on at least one end side has a nipple chamber having a chamber opening and mutually spaced apart chamber walls. The nipple chamber on at least one of the chamber walls has a delimiting element. The cable nipple when introduced into the nipple chamber by way of the chamber opening engaging below the delimiting element.

Abstract: An automatic sliding door cable mechanism with a take up guide member (46) mounted in a drum (14) for taking up slack of a cable during installation of the cable. A second drum (16) has an elliptical profile drum helix (96) for increasing durability of the operating cable for the automatic door.

Abstract: In a rope hoist (9), the output shaft (37) of the gearing (19) is provided in one piece with an end plate (57). This end plate (57) is designed in such a way that it can be inserted into a locating seat (66) of the tubular rope drum (17). The end plate (57) is screwed in the rope drum (17) by means of radial fitting screws (72). There is also a recess (67) at the other end of the rope drum (17), and a similar end plate (75) can be fastened in this recess (67) in the same manner. This other end plate carries a bearing journal (76). On account of this arrangement, the manufacture of the rope drum (17) and the entire assembly are simplified, complicated shaft joints between the output shaft (37) and the rope drum (17) being dispensed with on account of the mounting of the rope drum (17) by means of the output shaft (37) of the gearing (19). In addition, the rope hoist (9) may be split up into comparatively small subassemblies for dispatch.

Abstract: A winch has two portions of respectively different diameters. A ridge between them permits line to be flipped from the larger diameter portion to the other. Surface treatments of the two portions may be different, with that on the larger diameter portion being less aggressive than that on the smaller.

Abstract: A sailboat winch used for trimming lines of alternate sails, such as a jib and a spinnaker, has a drum with upper and lower drum portions of different diameters separated by a continuous radially projecting lip. The upper drum portion has a first diameter and is used for trimming the jib at maximum power. The lower drum portion has a diameter greater than the first diameter and is used for trimming the spinnaker lines. The radial extent of the lip is sufficient to prevent a line, when wrapped on the lower drum, from slipping upwardly and becoming disengaged from the lower drum.

Abstract: A drum for winding a cable attached to an overhead door includes a hub having a central aperture for accepting a shaft, a radially extending boss formed on the hub and a threaded aperture extending through the boss for retaining a threaded fastener for releasably attaching the hub to a shaft extending through the central aperture, a web attached in a central portion of the hub, the web extending radially outwardly at an angle of approximately 60.degree. with respect to the longitudinal axis of the hub, and a cable support extending about and being attached to the web, the cable support having a multiturn generally helical cable winding groove formed in an outer surface thereof.
