Claims
- 1. In combination with a coffee maker having a filter basket in spaced, overlying relation to a coffee pot support, the improvement comprising:
- a water holding tank;
- liquid flow control means for adding water to said holding tank up to a first liquid level;
- heating means for heating water in said holding tank;
- siphon means, including a bight portion extending above said first liquid level, for selectively transferring heated water from said holding tank to said filter basket; and
- means for submerging the bight portion of said siphon to effect said transfer of heated water.
- 2. The combination of claim 1 wherein said means for submerging said bight portion includes float means.
- 3. The combination of claim 2 wherein said flow control means includes a water inlet line;
- valve means for opening and closing said line; and
- said float means actuating said valve means.
- 4. The combination of claim 1 wherein said siphon means includes vent means communicating with said bight portion.
- 5. In combination with a coffee maker having a filter basket in spaced, overlying relation to a coffee pot support, the improvement comprising:
- a water holding tank;
- said holding tank being closed except for standpipe means upstanding from a top wall thereof and a siphon tube, including a bight portion, intercommunicating the interior of said holding tank and transfer tank underlying said holding tank;
- the cross-sectional area of said standpipe means being small as compared with the cross-sectional area of said holding tank;
- the bottom of said holding tank including a well;
- the shorter, inlet end of said siphon tube disposed within said well and the longer, outlet end thereof extending through the bottom of said well;
- the bight portion of said siphon tube disposed within said standpipe means and above said top wall;
- liquid flow control means, including a float, for adding water to said holding tank up to a first liquid level below said siphon bight portion;
- said float being disposed for movement at least partially within said standpipe means;
- heating means for heating water within said holding tank;
- metering means for transferring hot water from said transfer tank to said filter basket; and
- means providing access for depression of said float so that, when said holding tank is filled to said first liquid level with hot water, and said float is depressed, hot water rises within said standpipe means and submerges the bight portion of said siphon to initiate hot water flow to said transfer tank and filter basket.
- 6. The combination of claim 5 including a vent tube for venting the bight portion of said siphon tube.
- 7. The combination of claim 6 wherein said standpipe means comprises separate standpipes for said siphon tube and float.
- 8. A method of making coffee, comprising:
- heating a first body of water to coffee brewing temperature in a holding tank;
- floating a buoyant member in said first body of water;
- depressing said buoyant member in said first body of water and raising the level thereof;
- transferring substantially all said body of water to basket contained coffee grounds;
- introducing cold water to said holding tank to constitute a second body of water therein;
- refloating said buoyant member in said second, body of water and valving off said cold water; and
- heating said second body of water preparatory to making additional coffee.
