Abstract: The present invention features a bread-making machine that has a kneading paddle which remains in the bucket after the baking cycle. The bread-making machine automatically entraps, or vertically constrains, the kneading paddle to the rotating drive shaft. Upon the initial rotation of the drive shaft, the paddle shifts backwardly with respect to the drive shaft under a reactive, inertial force. The paddle will rotate approximately twenty-five degrees in a counterclockwise direction with respect to the shaft. This is made possible by the looseness of the fit of the drive shaft within the paddle's bore. A lip positioned on the top of the drive shaft will engage the top surface of the paddle hub, when the paddle is caused to shift. This engagement will capture the paddle, causing it to become vertically constrained to the drive shaft. Upon completion of the baking cycle, the baked bread can be removed without the paddle, which remains affixed to the drive shaft.
