  • Rotary drive mechanism and appliance timer/sequence switch utilizing same
    Patent number: 6718838
    Abstract: A rotary drive mechanism for use with a timer/sequence switch in an appliance is presented. The mechanism converts linear motion from a cam tracker following a programmed cam track to rotary motion to drive a vent damper in an appliance. The rotary motion output is derived as a multiple of the input linear motion through a gear set. This input linear motion is translated to rotary motion imparted to a tracking rod, which is coupled through the gear set to an output actuating rod. Tracking by a tracking lobe is accommodated by a spring bias force applied though a bias lobe that counteracts the force applied by the cam track. Alternatively, tracking by a tracker is accommodated by a spring bias force applied through a torque arm of the tracking rod that also counteracts the force applied by the cam track.

  • Electromechanical programmer/timer
    Patent number: 5510585
    Abstract: A programmer/timer for appliances having cam actuated switches with a cam drum advanced by a motor driven four-stage speed-reducing gear train with a missing teeth type intermittent device. The third step gear is readily interchangeable for changing the rate of cam advance. An auxiliary housing with auxiliary cam drum and switches may be added without altering the basic configuration of switches and advance mechanism.
