摘要: An ornament and display rotator has a reduction geared rotational shaft (3) of miniature motor (2) extended from an apex (4) cone-shaped housing (1). Ornament attachment means (14, 17, 18, 23, 24, 51) adaptable to wide variety ornaments (6) other objects for rotation are provided on the (3). Linear bearing (25, 29) also is as needed vertical load relationship between cone (1) Adaptable base (9) structures provided. The stored energy motors (47) gas powered (42) in addition small electrical (2).
