    • The ornamental display assembly according to this invention incorporates a pair of coaxial support members (30, 36) and has a decorative element (34, 38) mounted on each support member (30, 36). A cam drive system (18) provides one support member (36) with reciprocating motion while providing the other support member (30) with rotating motion. The drive system (18) may include an eccentrically mounted circular cam (26) in frictional contact with a drive disc (32) associated with the ends of the support members (30, 36), or may include a centrally mounted cam member (52) having an offset cam stub (54) which engages a slide member (62) to provide the reciprocating motion and which may be either in frictional contact with a drive disc (56') to supply the rotating motion, or may be drivingly connected to the drive disc (56) via interengaging gear teeth (60). In each case, the sole power supply comes from the output shaft (24) of a power source, such as a music box mechanism (16).
    • 根据本发明的装饰显示组件包括一对同轴支撑构件(30,36),并且具有安装在每个支撑构件(30,36)上的装饰元件(34,38)。 凸轮驱动系统(18)提供具有往复运动的一个支撑构件(36),同时为另一个支撑构件(30)提供旋转运动。 驱动系统(18)可以包括与与支撑构件(30,36)的端部相关联的驱动盘(32)摩擦接触的偏心安装的圆形凸轮(26),或者可以包括中心安装的凸轮构件(52) )具有与滑动构件(62)接合以提供往复运动的偏移凸轮短柱(54),并且可以与驱动盘(56')摩擦接触以提供旋转运动,或者可以驱动地连接到 驱动盘(56)经由相互啮合的齿轮齿(60)。 在每种情况下,唯一的电源来自诸如音乐盒机构(16)的电源的输出轴(24)。
