Clock Conservation Project: A.Brocot and Delletrez c.1850
One of my recent projects is a 19th century French clock signed A.Brocot and Delletrez. I found a description of the mechanism in Chavigny's work on the Brocot family, which revealed that a patent was issued for this mechanism in around 1850 by Antoine Brocot.
