Notes
L. A. Jarossay One of the most inventive clockmakers from the middle of the 19th century, he was especially known for his research into worm-screw sear-trains. He took out a patent in 1844 on the subject and in again in 1850, on its application to clocks and regulators with the idea of reducing the costs of production.
