Micrometer Scale

Description:

This is a robust one pan balance with an iron and marble base, and a tag on front that reads “The / Micrometer / Balance / Scale Co. / Troy, N.Y. / Patented Nov. 22 – 1892 / Mar. 22 – 1898 / Jul. 21 – 1903.” According to an early account, it had no springs or loose weights, but the weight end of the beam is transformed into a quick acting screw, and upon this screw the weight is moved with great accuracy.

The Micrometer Balance Scale Co. of Troy, N.Y., introduced this form in 1897. The Dodge Mfg. Co., of Yonkers, was selling these devices by 1905.
