Footnotes
Mercer (Chronometer Makers of the World, NAG Press 1991) notes that Bliss and Creighton were established in New York in 1837 and continued in business until 1855. Their patent number 4135 relates to the use of a double balance spring "To obtain a more fractional and equal expansion and to apply more effective means for regulating the vibrations of the balance when in use."
