    • A rotator for a hanging display such as a mobile, hanging plant or the like having a self-contained power supply. The apparatus comprises a cylinder for containing flashlight batteries adjacent one another and for containing motor means to drive a geared shaft by which a display is suspended and rotated. Off-on operation and series battery interconnection are effected by the positioning of a rotatable, electrically conductive circular top plate confronting the ends of the batteries. An opening in the rotatable plate is provided for replacement of the batteries. A tab on the top plate permits the plate to be rotated and to be suspended.
    • 用于悬挂显示器的旋转器,例如具有独立电源的移动式,悬挂式设备等。 该装置包括用于容纳彼此相邻的手电筒电池的气缸,并且用于容纳用于驱动显示器悬挂和旋转的传动轴的马达装置。 接通操作和串联电池互连通过面对电池端部的可旋转的导电圆顶板的定位来实现。 提供可旋转板中的开口用于更换电池。 顶板上的突片允许板旋转并悬挂。
