ABSTRACT:
Rotation of a cam means of a timing mechanism is provided by three sets of axially aligned ratchet teeth having different major and minor diameters and a drive pawl selectively engaging the three sets of teeth.
The arrangement provides a means to delay the actuation of switches which control the functions of an appliance.
In one embodiment, the relationship between the three sets of ratchet teeth allows a variable range of interval times in a single timer program. That is, the arrangement provides variable dwell times versus cam advance times.
