    • A winch (10) capable of hauling a cable comprising a length of rope (41) and a length of chain (34) connected end-to-end especially by a shackle (43), the winch including a drivable rotatable member such as a shaft (20) and a chainwheel (23, 24) adapted to haul the length of chain (34). A rope sheave (26), adapted to haul the length of rope (41), and the chainwheel are connected to the rotatable member, and a sheave disengaging member (36) is actuated by the presence of the chain (34) in the chainwheel (23, 24) to disengage the sheave from the rotatable member.

    • A winch (1) particularly suitable as a yacht sheet line winch. In traditional manner the winch (1) preferably incorporates a cylindrically shaped drum (2) having a shoulder lower end section (2a), in use, the drum (2) being intended to be rotated, such as by handle (10), about a substantially vertically disposed axis. Longitudinal or axially extending recesses (3) are incorporated at radially spaced apart intervals about the drum (2) with the land sections (4a) therebetween maintaining the radius of curvature of the drum (2). The recesses (3) provide additional frictional grip on a sheet line (8) retained thereon. Preferably the recesses (3) terminate in adjacent spaced relationship to a shoulder end (2a) to provide a recess free zone (6). The recesses (3) are configured to provide an obtuse angle between a face (4) of the drum (2) and the adjacent intersection face (5) of a recess (3) this "transition" angle being identified as angle "X" on the accompanying drawings. Preferably both the depth and width of the recesses (3) and the diameter of the drum increase toward a top of the drum (2). This geometry of the recess (3) configuration and layout on a drum (2) tends to spread the frictionnally forces provided thereby away from a first turn (7) of sheet line (8) on the drum (2).
    • 绞车(1)特别适合作为游艇板卷绞车。 以传统的方式,绞车(1)优选地包括具有肩部下端部分(2a)的圆柱形鼓(2),在使用中,滚筒(2)旨在例如通过手柄(10)旋转,大约 基本垂直设置的轴线。 纵向或轴向延伸的凹部(3)围绕滚筒(2)以径向隔开的间隔结合,其间的陆部区段(4a)保持滚筒(2)的曲率半径。 凹槽(3)在保持在其上的片材线(8)上提供额外的摩擦抓握。 优选地,凹部(3)以与肩端(2a)相邻的间隔的关系终止以提供无凹槽区(6)。 凹部(3)构造成在滚筒(2)的面(4)和凹部(3)的相邻交叉面(5)之间提供钝角,该“过渡角”被标识为角度“X” 在附图上。 优选地,凹部(3)的深度和宽度以及鼓的直径朝向鼓(2)的顶部增加。 在滚筒(2)上的凹槽(3)构型和布局的这种几何形状倾向于将由此提供的摩擦力扩展到远离卷筒(2)上的片材线(8)的第一匝(7)。
