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.
