German Style Movements has been popular in Europe but were relatively new to America during the time when Chauncey Jerome discovered them in use in Virginia in the mid 19th century and incorporated them to create the brass movement. The brass movement proved superior to the wooden movements of the day for two reasons. Wooden movements could warp and deflect with the temperature and climate allowing those clocks to easily malfunction. Jerome also devised a method to create the brass gears by stamping them instead of casting them in an industrial mold.
Mahogany used to create the wooden casework was grown, cut and shipped from forests in central Southern America mainly from the forested Amazonian region of Brazil. In the 1851 it was recorded that nearly 300,000 feet of mahogany was imported for the purpose of was imported along with rosewood and nearly 1.5 million feet of pine lumber.
Radium used for painting the dials of many clocks from the New Haven Clock Company was mined in the Shinkolobwe Mines in the South East Corner of the Belgium Congo during the early part of the 20th century. The mine was discovered in the early 20th century and contained elements such as uranium as well. This led this mine to later be the origin for the material used to supply material for the Manhattan Project.
Ever since the early 1840’s the founder of the New Haven Clock Company Chauncey Jerome has established networks to the regions of the British Isles, British India and Canada as well as Peru, the Ottoman Empire and Qing Dynasty China. Nearly 75,000 clocks were being produced each year along with nearly 150,000 to 176,000 movements. And almost $100,000.00 in wages was being paid per month to nearly 405 workers.
Using is power as Mayor of New Haven in 1854 Jerome was even able to negotiate the lowering of tariffs on American Clocks from 20% to 10% to England and the British colonies, which made up a substantial share of the global market for the company.
