  • Door for brew kettle
    Patent number: 4599991
    Abstract: A brew kettle in which the upper portion of the kettle wall includes a manhole and a vent hole and in which a door is pivotally mounted inside the upper wall portion such that, in its closed position, it closes off the manhole. The door is normally open due to the force of its own weight, and a counterweight arm is mounted on the door and extends inside the kettle so as to substantially reduce the force necessary to close the door.
