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.

Abstract: A compact transmission for an automatic washer which converts unidirectional rotary motion to oscillating rotary motion without the use of gears is provided. An input shaft is rotatingly driven by an electric motor and has a reversing thread connection to an intermediate member through a thread follower to cause the intermediate member, which is restrained against rotation, to reciprocate vertically. The intermediate member has an angled cam slot and follower connection with an output shaft which results in oscillating rotary motion of the output shaft. The drive member can be carried on the outside of the coaxial input and output shafts or can be sandwiched between the output shaft and coaxial, nested input shaft.

Abstract: A method for laundering a textile wash load is provided for use in a vertical axis washing machine in which a concentrated detergent solution containing a detergent concentration of 0.5% to 4% by weight is continuously applied to a spinning wash load for a predetermined time period to thouroughly wet the clothes load. The amount of detergent solution used is only slightly in excess of the amount required to saturate the clothes load at the given rotational speed. After the time period, additional water is added to the solution to dilute it to a normal concentration and then mechanical agitation and rinsing steps are conducted to complete the wash cycle.

Abstract: A clothes rollover agitation system is provided for a vertical axis automatic washer in which the agitator has a skirt portion that has an inner portion which extends outwardly and downwardly and an outer portion which extends outwardly and upwardly to assist the clothes within the washer to undergo a 180.degree. direction reversal in the bottom of the wash basket. The skirt portion stops short of the basket side wall and a removable ring member is secured to the basket wall to continue the upward and outward shape toward the sidewall. A plurality of buttons engagable in holes in the basket sidewall are used to secure the ring to the sidewall.

Abstract: An air actuated lint removing system for cleaning lint filters in clothes dryers includes means for moving the lint filter and an air flow directing means with respect to one another to remove accumulated lint, and lint transporting means to move the lint to a lint collection reservoir.

Abstract: A fluid additive dispenser is provided for a clothes dryer which has a reservoir for storing a quantity of liquid additive, a body of porous material acting as a wick and having a first surface exposed to the tumbling clothes load within the dryer and a second surface for receiving the fluid additive, a conduit connecting the reservoir with the second surface of the material and a valve interposed within the conduit which is selectably operable to deliver a predetermined quantity of liquid to the second surface of the porous material. The reservoir has a horizontal cross section greater than the horizontal cross section of the conduit and is positioned above the valve to provide a relatively constant fluid head to the valve to assist in the accurate metering of the fluid through the valve. The porous material is held in a holder which is mounted to a fixed rear bulkhead of the drum.

Abstract: A flexible vane agitator is provided for use with a high stroke rate automatic washing machine in which the vanes on the agitator are very flexible and have a special configuration in which the thickness of the vanes decreases from a base end at the agitator barrel to a point at least half way to the end of the vane and then increases in thickness to the radial tip such that the tip is bulbous and is thicker than any other portion of the vane except for the base. The bulbous tip is rounded and has a shorter height than the base end.

Abstract: An agitator thruster is provided for an automatic washer for increasing the rollover of clothes during the agitation portion of a washing cycle wherein the thruster moves in a vertical reciprocating motion by action of a pin carried by the thruster engaging angled side walls of a channel in the agitator barrel and being caused to move in one direction around the channel circuit, up along one angled channel wall and down along another.

Abstract: A means for operating a washing machine transmission in a neutral state is provided which includes a reversible drive gear for driving the transmission in a first agitate direction and an opposite spin direction. A drive pawl is pivotally mounted on the drive gear. Pawl pivoting means, being a circular control spring with an outwardly extending tang is selectively rotatable against either side of the pivoted pawl and a latching pawl selectively captures the tang when the drive gear is rotating in the spin direction to operate the transmission in a neutral state until the rotation of the spin gear is interrupted. Means are provided on the latch pawl to prevent relatching of the control spring if the rotation of the drive gear is subsequently interrupted.
