<p>41 PR 6080 A variable drive coupling link assembly is utilized to drivingly couple a rotary motor operator mechanism to a circuit breaker mechanism operator member such as to provide a coasting zone intermediate the end of an operating member charging stroke and the start of an operating member charging stroke and the start of an operating member return stroke during which the motor operator mechanism may coast to a stop. The link assembly is structured to abruptly shorten its effective driving length at the conclusion of a charging stroke and to re-establish its full effective driving length by the conclusion of the return stroke, thereby rendering the charging and return strokes of the operator member equal in length.</p> |
