Abstract
A uni-direction rotation device in a cam-operated timer is accomplished by coupling the timer control shaft to the camstack with a semi-circular tang and semi-circular slot connection. When the timer control knob is rotated in the biased or right direction, the slot is coupled to the tang, and the timer can be set. But when the timer control knob is rotated in the unbaised or wrong direction, the slot is uncoupled from the tang and the timer control knob rotates freely, so the timer cannot be set.
