    摘要： 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.

    摘要： A universal cable winding drum for winding and unwinding a cable connected thereto. The drum has a hollow central hub for securement to a rod associated with a winding mechanism to impart rotation to the drum. A cylindrical cable supporting wall is connected to the hub and extends thereabout for supporting a plurality of windings of a cable thereon. The cable supporting wall has a plurality of cable guide channels formed therein in side-by-side relationship and are interspaced at overlapping end regions whereby to constitute right and left hand cable guide channels so that the cable can be wound thereon from either side of the drum. The end of the cable is secured through an end one of the channels on the cylindrical wall of the drum.

    摘要： The disclosure is of a system for maintaining tension in a cable during winding off or on a power driven cable drum. The cable winds off or back onto the cable drum over a roller means, e.g., between a pair of parallel geared-together traction rollers, or over a sheave, as another example, with a non-slip engagement therewith. The non-slip engagement avoids wear on the cable, and the life of the cable is greatly extended. To permit this, a frictional slip clutch is placed in a power transmission interposed between the power driven cable drum and the non-slip drive rollers, or sheave. The wear that formerly eroded the cable now occurs in the friction slip clutch, whose parts can always be quickly and inexpensively replaced. The system also includes certain one-way roller clutches, and gears, so arranged as to normally overdrive the roller means, or sheave, in paying out cable, and to retard the cable during winding in. The arrangement provides gearing of a drive ratio tending to overdrive the cable in paying out, and to underdrive, or retard, during winding in, the necessary slip always being accommodated by the slip-clutch. The cable is thus always under tension, and fouling of the cable is prevented.

    摘要翻译： 本公开是一种用于在卷绕期间或在动力驱动的电缆卷筒上保持电缆中的张力的系统。 电缆通过辊子装置（例如在一对平行的齿轮传动牵引辊之间）或者在滑轮上卷绕或回到缆索滚筒上，作为另一个例子，与其滑动接合。 防滑接合避免了电缆上的磨损，并且电缆的寿命大大延长。 为了允许这一点，摩擦滑动离合器被放置在插入在动力驱动的缆索滚筒和防滑驱动辊或滑轮之间的动力传动装置中。 摩擦滑动离合器中现在发生的电缆现在已经磨损，其部件总是可以快速，低成本地更换。 该系统还包括某些单向辊式离合器和齿轮，其布置成正常地过度驱动辊子装置或滑轮，用于支付电缆，并且在卷绕期间延迟电缆。该装置提供传动比趋向于传动比 过度驱动电缆，以便在松动离合器中总是被容纳的必要的滑移中，支付出来，并且在下降或者延迟。 因此，电缆总是处于紧张状态，并且防止了电缆的结垢。
