Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
An automatic beverage making apparatus comprising a stand; a receptacle associated with the stand for receiving the solid material from which the beverage is to be made; a conduit within the stand and having an inlet for connection to a water supply and an outlet to said receptacle, an electrical heater within said conduit and arranged to heat water continuously passing through a flow passage defined between the heater and the inner wall of the conduit when the apparatus is in operation; valve means associated with said conduit, normally closed and operable to permit water to flow through said conduit; means to supply electric current to said heater; switch means in said stand; and timing means provided in said stand and operable by switch means to open said valve means and energize said heater for a predetermined time sufficient to supply a predetermined quantity of heat to a predetermined quantity of water as it flows through said conduit, to bring water to the temperature required to brew the beverage said timing means then closing said valve means, and de-energizing said heater.
