Method for manufacturing a clockwork wheel

Image Number 7 for United States Patent #6082001.

A clockwork wheel (1) including a plate (3) provided with a first series of peripheral teeth (4) and a second series of teeth (5) arranged at right angles to the plate is manufactured in a strip of steel suitable for stamping and by means of a progressive forging die. In order to form the second series of teeth (5), a die perforated with a plurality of openings arranged in a circle is applied onto one face of the strip, and the flat face of a cylinder is pressed onto the other face of the strip to cause the steel to flow inside the openings of the die. The clockwork wheel is used as a setting wheel in a time or date setting mechanism.
