Abstract
When the axially movable shaft mounted in the hub of a program cam drum is moved inwardly a pin loosely mounted in a cross hole on the shaft will move into engagement with teeth on a drive sleeve mounted between the shaft and the drum hub while a washer fixed on the end of the shaft moves to actuate a slider which then actuates and opens a line switch to take power off the appliance controlled by the timer. Engagement of the pin with the sleeve completes the drive to the sleeve and the sleeve is keyed to the drum by lugs projecting to slots in the hub. Now the shaft can rotate the timer drum without power applied to the appliance. When the shaft is pulled out, the line switch closes and the drive pin is disengaged from the teeth and rotation of the shaft is not effective to rotate the timer.
