ABSTRACT:
The present invention concerns a spin basket clutching device which includes a flotation device which locks the spin basket to an agitator in response to the level of wash liquid in the basket. During a wash step, the basket will be full of liquid and the flotation device floats within an inverted pocket located on the agitator skirt. During a spin step, the basket will be empty of liquid and the flotation device will drop partially out of the inverted pocket and rest partially within a pocket on the spin basket, thus locking the agitator to the spin basket for concurrent rotation. Also disclosed is a device which responds oppositely to the level of wash liquid in the wash tub locking the spin basket to the wash tub to prevent rotation of the basket during agitation of the wash liquid by the agitator during the wash step and unlocking the basket from the tub in a low liquid level step such as spin.
