Abstract
A spring-biased valve lever on the bottom of a coffee maker brew basket is pivoted to open the brewed liquid outlet of the brew basket in response to the rotation of a valve actuator caused by the placement of a carafe on the warmer plate of the coffee maker. The valve actuator is mounted for rotation about a vertical axis and has two horizontally movable arms, one which is engaged by the carafe and one which engages and presses downwardly on the rearward end of the valve lever.
Claims8
A coffee maker having a pause-serve mechanism comprising:
- a housing having a base for supporting a carafe, an upright pedestal, and a head supported by the pedestal;
- a brew basket supported by the head over a carafe supported on the base, said brew basket having an outlet through which brewed coffee can flow downwardly into the carafe;
- a valve lever pivotally mounted on the bottom of the brew basket having a forward end and a rearward end;
- a valve element mounted on said valve lever intermediate said forward end and said rearward end and operative to open and close said outlet;
- a spring that biases said forward end of said valve lever downwardly into a position in which said valve element closes said outlet;
- and a valve actuator for moving said valve lever into a position effective to open said outlet when a carafe is located on said base, said valve actuator comprising a vertically-oriented shaft pivotally mounted on said pedestal for rotation about a vertical axis, a lower arm fixed to said shaft for engagement by a carafe positioned on said base, and an upper arm fixed to said shaft that presses said rearward end of said valve lever downwardly to move said valve element to open said outlet in response to the carafe being positioned on said base.
