Abstract
A coffee dispenser particularly constructed to measure and dispense finely ground powdered coffee by providing an agitator for the lower portion of the hopper including an agitator portion moving through the discharge opening of the hopper to positively prevent bridging and clogging of the powdered coffee in the bottom portion of the hopper.
Claims5
A ground coffee dispenser comprising
- a hopper for storing a supply of ground coffee to be dispensed,
- said hopper having a bottom discharge opening with side walls sloping downwardly to the discharge opening,
- an agitator pivotally mounted in the hopper and having a spring-loaded arm portion swinging downwardly through the said discharge opening during the discharge of coffee therethrough, and including a spring to urge the arm portion downwardly,
- a slide closure plate having an open discharging position and a closed position for normally closing the discharge opening to support the lower end of the spring-loaded agitator arm portion riding on the top surface of the plate when the same is in closed position,
- a batch measuring compartment aligned with the hopper discharge opening to receive a measured batch of coffee therethrough and having a discharge trap door at the bottom thereof for closing the compartment when the closure plate is in said open position, but swinging down into open dumping position when the slide closure plate is moved into said closed position,
- means for activating said closure plate to slide the same into said open position for discharging material through said opening and associated with said agitator to permit the spring to oscillate the arm portion downwardly into the opening whenever the closure plate is shifted from said closed position to said open position to agitate the coffee and ensure the free flowing action of the coffee through the opening when the closure plate is in said open position.
