Claim 1
Independent Claim
211 words
In apparatus for dispensing controlled quantities of liquid, the combination of: a container for the liquid; an outlet sleeve in said container with an inner end within said container and an outer end outside said container; an auger positioned in said sleeve; means for rotating said auger to advance a quantity of liquid through said sleeve; a closure for said outer end of said sleeve and including a second sleeve slidable in said outlet sleeve and carrying sealing means for engaging said outer end, with said second sleeve having an outlet opening in the side wall thereof; and means for moving said closure into and out of sealing engagement with said sleeve with said means for moving being capable of moving said closure out of sealing engagement to dispense liquid without removing said second sleeve from said outlet sleeve, and including an electrical solenoid and plunger, a lever with one end coupled to said plunger and with the other end coupled to said closure, mounting means for pivotally supporting said lever, and a spring engaging said mounting means and said lever for urging said lever and closure toward said sleeve, with said solenoid when energized acting on said plunger to move said lever and closure against the action of said spring.
