Balance
Balance
- Description
- This spring scale is marked “MORTON & BREMNER’S / SPRING BALANCE MADE / BY THOMAS MORTON / TO WEIGHT 30 W BY OUNCES” and “EACH 10 lb. IS MARKED ON THE SLIDE / THE INTERMEDIATE WEIGHTS ON THE CIRCLE” and “1867” and “WARRANTED.” It was probably part of the model that accompanied Richard Murdoch’s application for a patent for an “Improvement in Suspending Scale Pans.” Murdoch’s patent (#75,448 of 1868) described the pans, not the scale itself.
- Thomas Morton and Andrew Augustus Bremner, both of New York, began in business in 1841, making spring balances and weighing devices. Bremner left the firm in 1855; Morton was still in business in the 1870s.
