Control apparatus for an intermittently rotated indexed wheel
A driven or indexed wheel for a timepiece driven step-by-step by a balance staff of a timepiece. A rockably supported level has a pawl thereon resiliently biased rotationally by a free end of a spring lever to engage peripheral teeth on a lock wheel that is fixed to the wheel driven stepwise.

| description | A driven or indexed wheel for a timepiece driven step-by-step by a balance staff of a timepiece. A rockably supported level has a pawl thereon resiliently biased rotationally by a free end of a spring lever to engage peripheral teeth on a lock wheel that is fixed to the wheel driven stepwise. The force applied by the spring lever can be varied while maintaining precise positioning of the indexed wheel as it steps rotationally. |
