ABSTRACT:
A digital clock is coupled to a cam means of a timing mechanism so that the clock can indicate the time remaining of a cycle provided by the cam means. One of the display wheels of the clock is intermittently rotated through the stored energy of a torsion spring, the energy being stored when the wheel is prevented from rotating by a slider which engages the wheel. A second display wheel is intermittently rotated as the first wheel is rotated through a geneva gear system which couples the two wheels together.
