Abstract
Abstract A teakettle for boiling water, the covered kettle having a spout projecting therefrom whose mouth is normally closed by a whistle cap having an extension arm terminating in a pinion mounted for rotation at one end of a bail secured to the kettle and serving as a handle therefor. The pinion is engaged by a rack attached to the front end of an arcuate strip slidable within the hollow bail, the rear end of the strip being coupled through a slot in the bail to an external finger pad. To pour boiling water from the kettle, the user grasps the bail with his hand and manipulates the finger pad with his finger to push the pad forward, thereby advancing the rack and causing the pinion to rotate and lift the cap from the mouth of the spout. Release of the finger pad causes the cap to drop back in place on the spout and to return the finger pad to its initial position.
