Abstract
A three-handed clock has a single movement to rotationally drive the second, minute and hour hands. The rotary output of the movement is transmitted directly to the second hand and is transmitted through a transmission belt to the minute and hour hands. The use of the transmission belt eliminates the need for a gear train to drive the minute and hour hands thereby providing greater design flexibility and ease of assembly and maintenance.
