ABSTRACT:
A washing machine with an improved mode shifter comprises a basket for holding an article to be washed, a basket collar coupled to the basket, an agitator disposed within the basket, an agitator collar coupled to the agitator, a brake for reducing a rotational velocity of the basket, a brake collar coupled to the brake, a first spring disposed around the basket collar and the agitator collar, and a second spring disposed around the first spring, the basket collar, and the brake collar. The mode shifter provides a mechanically simple, inexpensive, and reliable mechanism for shifting from the agitation mode to the spin mode to the brake mode in a wash cycle.
