Additive dispensing system
First Claim
1. In an automatic washer having a basket, an outer tube and an additive dispensing system including a multi-compartmented dispenser, a liquid flow diversion arrangement having a liquid diverter mechanism for selectively diverting liquid into pre-selected dispenser compartments for flushing the additives into the tub at pre-determined times during a cylce of the washer, the improvement comprising:
- a. a pivotal body with a liquid inlet opening at one end connected to a water inlet means and a nozzle at the other end with a liquid outlet opening in liquid flow communication with the dispenser, andb. a three position nozzle control mechanism including two solenoids with plungers, a lever arm connecting the solenoid plungers, biasing means to center the lever arm when both solenoids are de-energized, and a rod connecting the lever arm and the nozzle whereby the nozzle is pivoted to a different position responsive to separate energization fo each solenoid and de-energization of both solenoids.

Abstract
An improved additive dispensing system for sequentially dispensing a plurality of treating agents into the wash tub of an automatic fabric washing machine at predetermined times during the washing cycle. A plurality of compartments are provided for retaining the various laundry additives to be dispensed into the wash tub. A liquid flow diversion arrangement having a diverter for selectively diverting liquid into pre-selected dispenser compartments is provided and includes a pivotal body with a liquid inlet at one end connected to a water inlet and a nozzle at the other end in liquid flow communication with the dispenser. A three position nozzle control mechanism includes two solenoids with plungers, a lever arm connecting the solenoid plungers, a biasing spring to center the lever arm when both solenoids are de-energized, and a rod connecting the lever arm and the nozzle whereby the nozzle is pivoted to a different position responsive to separate energization of each solenoid and de-energization of both solenoids.
