Abstract
A kettle has a handle with a channel formed therein. The channel houses a slider with a push trigger on one end and a toothed rack on the other. A compression spring is positioned between the channel and the slider. A ratchet tooth gear is connected to the kettle spout cover/whistle. The gear is pivotally connected to the handle. The toothed rack of the slider engages the ratchet tooth gear so that a force applied to the trigger moves the cover to the open position. The removal of such force causes the cover to move to the closed position under the influence of the compression spring. The kettle may include a stop that locks the cover/whistle in the open position.
