faces the underside of the basket 16 in vertical alignment with a pocket 162 disposed within the deep pocket 170 is a flotation device 180 which may be exactly the same as flotation device 130 however in mechanism 150 the flotation device 180 serves to lock the basket to the tub when the wash liquid level is high it is appreciated from fig2 and 6 that when there is no wash liquid in the tub 14 above the level of the ring 160 the flotation device 180 does not float and instead rests within deep pocket 170 however when tub 14 is sufficiently full of wash liquid the flotation device 180 will float upwards until it engages one of the shallow pockets 162 on ring 160 to lock the tub 14 to the basket 16 thus when the washer is in a wash step and full of wash liquid the basket 16 will be locked to tub 14 and will be prevented from moving in response to agitation of wash liquid conversely when the washer is in a spin step the basket 16 will not be locked to tub 14 and will be free to spin two arrangements may be employed to permit the flotation device 180 to rest within the deeper pocket 170 when the wash liquid is extracted from the wash tub 14 in the first arrangement shown in the drawings no drain is provided to permit accumulated liquid to drain from the pocket 170 however the flotation device 180 is of such specific gravity that it barely floats in the remaining liquid and will be contained within the pocket 170 thus the mechanism 150 will.
