<p>TIMING APPARATUS The timing apparatus includes timer motor means having a rotatable output shaft rotatable through a revolution in a prescribed period of time, switching means adapted to be alternately switched between at least two discrete positions for respectively operating corresponding electrical output devices, indicating means operatively connected to the output shaft for movement in unison with the output shaft and for selective independent movement with respect to the output shaft in response to manual adjustment for adjustably setting the times at which the switching means will be operated to effect such switching between the electrical output devices, and actuating means operatively connected to the switching means and adapted for periodic movement opposed first and second positions in response to displacement of the indicating means. Each of the motor means, switching means and actuating means are supported by a supporting member and the output shaft of the motor means extends through the supporting member. The timing apparatus, further includes, biasing means interconnecting said switching means and said actuating means for resiliently snapping and maintaining the switching means in respective discrete positions.</p> |
