Timing mechanism with improved clutch assembly |
摘要 |
A clutch assembly permits a manual setting of a timing mechanism camstack by an appliance operator and at the same time insures that the camstack cannot be manually set during the time that electrical power is being supplied to the timing mechanism. The assembly includes a support and a camstack, a shaft and a bearing mounted in the support for rotation about a common axis. First clutch teeth are integrally formed within the bearing and second clutch teeth are integrally formed within the shaft. The bearing is mechanically coupled to the camstack via tangs on the camstack which pass through channels in the bearing. The shaft is axially movable from a first position in which the first and second teeth are engaged to a second position in which the teeth are disengaged. The ends of the teeth are formed and arranged so that no matter what relative rotational position about the axis the first teeth are with respect to the second teeth when the shaft is moved axially from the second position toward the first position, the teeth will engage.
