Abstract
A beverage brewing apparatus of the infusion type in which a hot water tank contains several infusion charges, the tank is connected at the top to a conduit extending to an infusion sprayer over a pan containing granular matter to be infused, replenishing water is supplied to the bottom of the tank and is used to force a top charge of water in the tank into the pan, a heater for the tank is controlled by a lower thermostat in the tank and an upper thermostat indicates when the top charge is at the correct temperature for infusion to take place. The arrangements ensure a ready supply of hot water for further infusions while reducing the instant power requirements for the heater.
