发明名称 Clock hand linkage and support assembly
摘要 A clock hand linkage and support assembly (10) for use with a clock drive mechanism (11) having limited driving torque and power supply and which rotationally increments a hand (14) in discrete intervals through a drive shaft (12) includes a hub (13) having a central portion (20) through which the drive shaft (12) may pass for free rotation about the drive shaft (12) and at least one angle bracket stay (24) for support of the hand (14). A compliant fastener (16) biases the hand (14) into flexible engagement with the angle bracket stay (24) preventing damage during shipment. A resilient drive linkage (18) is coupled to the drive shaft (12) by interference fit and is biased against the hub (13) by the compliant fastener (16) whereby the hand (14) may continually rotate with the hub (13) in controlled relation to the incremental movement of the drive shaft (12).
