Abstract
In a clothes washer of the type which has an array of tuckers and which is reciprocated vertically toward and away from the bottom of a container of washing liquid, a diaphragm is mounted to have an extended orientation during downward stroke for displacing liquid, and a relatively collapsed orientation during upward stroke, and a volume-outlining, clothes-restraining open uper structure provided over the diaphgram, this open structure extending upwardly from the diaphragm so that at least a part of it extends above the normal liquid level when the washer is in its lowest position. In action, as the diaphragm displaces liquid downwardly, the open structure, in following behind the diaphragm, restrains articles of clothes from moving inwardly over the diaphragm but allows liquid to move inwardly through the clothes and through the open structure to fill in behind the diaphragm. As it approaches the bottom of the container, the diaphragm applies an effective outward clothes-washing jet of liquid from between the diaphragm and the bottom surface of the container to prevent tangle of the downwardly-tucked clothes. During upward stroke the open structure and diaphragm are free to move upwardly with relatively low resistance.
