Abstract
A programmer for an appliance having a single timing motor drive for a rotating cam drum which actuates plural appliance program function switches. An advance pawl drives the cam drum in one direction when selectively engaged with a toothed wheel on the drum and drives through a first rotary frictional coupling. A gear train drives continuously through a second rotary frictional coupling and drives the cam drum in a reverse direction when the advance pawl is disengaged. When the pawl is engaged, the second rotary frictional coupling slips and is overdriven in a direction opposite its driving direction by said first frictional coupling.
