Unique Elisha Manross Steeple Clock, featuring hard-to-find brass mainsprings from 1847.
Elisha Manross, a pioneering figure in Connecticut clockmaking, began his career in 1812 at the age of 20. Despite being less commonly known compared to American clockmakers like Seth Thomas, New Haven, or Waterbury, Manross played a pivotal role in the development of the industry.
Working with brass mainsprings was a common practice during Manross's early years in clockmaking, from around 1836 to 1850. Brass was a workable and reliable material for producing mainsprings, but it was eventually replaced by tempered steel due to its superior properties.
The transition from brass to steel mainsprings was largely driven by two key factors: superior elasticity and strength, and greater durability. Tempered steel mainsprings could store more energy, deliver more consistent force, and recover their shape better after winding and unwinding cycles. They were also less prone to fatigue and permanent deformation over time, making them a more reliable choice for clock mechanisms.
Moreover, the improved timekeeping accuracy offered by steel mainsprings was a significant advantage. Clocks equipped with steel mainsprings were able to maintain more accurate and reliable time, contributing to the overall performance of the timepieces.
The advent of industrial steel tempering techniques around 1847 marked the rapid adoption of tempered steel mainsprings. Brass mainsprings, while once common, began to fade into history as steel offered a clear technical advantage for the demanding mechanical requirements of mainsprings in timepieces. This technological transition improved reliability and performance in clocks from the mid-19th century onward.
The Manross family, who continue to preserve and restore Elisha Manross's clocks, recently announced that the analyzed clock, made by Manross around 1847, features original and well-preserved brass mainsprings. Given the clock's rarity due to its brass mainsprings, it will not be a daily runner and will be preserved for its historical value.
In conclusion, the shift from brass to steel mainsprings in clockmaking was a significant event that improved the reliability and performance of clocks. Elisha Manross's clocks, including the one recently restored, serve as a testament to this historical transition.
Current world events have affected the Manross family, with their condolences to those affected by Covid-19. The family continues to work diligently to preserve and share the legacy of Elisha Manross and his contributions to clockmaking.
