  • Patent number: 4265100
    Abstract: A laundry additive dispenser for use with laundry appliances has a tiltable bin pivotally mounted for user access on a panel of the laundry appliance. The bin is divided into three sections which are exposed when the bin is tilted forward to a receiving position and may be filled with liquid or granular laundry additives. The bin is then tilted back to a dispensing position. The sections of the bin for dispensing liquid laundry additives each have a siphon therein. Solenoid operated valves selectively communicate each section with a water distribution path. When an appropriate valve is opened water flows in the proper section of the bin and when the water-additive solution reaches an appropriate level, siphoning action begins and the entire contents of the section is dispensed to a clothes treatment zone in the appliance. Each section is provided with an overflow tube to insure that the liquid level in the section does not reach a level so as to prevent the siphoning action.

  • Patent number: 4262870
    Abstract: A retractable self-leveling assembly for supporting a laundry appliance such as an automatic washer is connected at a rear base portion of the appliance. The assembly has two spaced apart upwardly and outwardly angled slots therein for slidably receiving pins which connect supporting feet to opposite ends of an adjustable tension bar generally at right angles thereto. In a deployed position, the feet extend below the laundry appliance and the weight of the appliance on the feet and tension bar combination causes the pins to slide in the slots to automatically position the feet to compensate for any unevenness in the surface on which the appliance rests. The tension bar may be manually extended to retract the feet into the appliance cabinet during storage or transport of the appliance.
