US 5,042,311 A · Secondary timer for program timer

Abstract

A secondary timer mechanism for controlling a secondary program function independently of a first program function. A main timer mechanism controls the first program function and is operatively driven by a motor. A second timer mechanism can be set independently of the main timer mechanism and engages the motor through a drive gear in a first axial position and is in non-engaging relation with the drive gear in a second axial position. The second timer mechanism includes a peripheral cam surface that cooperates with a cam follower to advantageously control selective electrical connection between contact portions. The contact portions regulate the secondary program function. Pins are operatively included in the second timer mechanism for maintaining an engaged relationship with the drive gear.

Dependent claims

A secondary timer assembly for controlling a secondary program function comprising:

a main timer mechanism including a first member selectively positionable for control of an associated first program function;
a secondary timer mechanism including a second member selectively rotatably user positionable independently of said main timer first member for control of an associated secondary program function;
common motive means for driving said main and second timer mechanisms and upon user movement of said second member of said secondary timer mechanism upon user movement to a first axial position said second member effects driving engagement of said second timer mechanism and thereafter upon rotary movement of said second member by said common motive means to a predetermined position, said second member automatically effects disengagement of said common motive means from said second timer mechanism.
