Abstract
Abstract A TIMER HAS A MANUALLY OPERABLE DIAL FOR SETTING THE TIMER TO RUN FOR A PREDETERMINED PERIOD OF TIME. THE TIMER INCLUDES AN ELECTRIC MOTOR FOR DRIVING THE DIAL BACK TO A ZERO SETTING POSITION. THE MOTOR DRIVES THE DIAL THROUGH A PLURALITY OF SELECTIVE DRIVE PATHS. THE TIMER INCLUDES A SHIFT MEANS COOPERABLE WITH THE DIAL AND WITH THE DRIVE PATHS. WHEN THE DIAL IS SET FOR SHORT TIME PERIODS, A HIGH SPEED DRIVE PATH IS AUTOMATICALLY ENGAGED. WHEN THE DIAL IS SET FOR LONG TIME PERIODS A LOW SPEED DRIVE PATH IS ENGAGED. THE TIMER AUTOMATICALLY PROVIDES MORE ACCURATE TIMING OF SHORT TIME PERIODS.
