Micrometer Scale

Description:

Robust one pan balance with an iron and marble base, and a tag that reads “THE MICROMETER / PATENTED NOV. 22, 1892 / MAR. 22, 1898 / JUL. 21. 1903 / THE DODGE MFG. CO. / YONKERS, N.Y.” An early account explained that this balance 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., a firm in Troy, N.Y. of which Charles Mattice was a founding director, introduced this form in 1897. The Dodge Mfg. Co., of Yonkers, was selling these devices by 1905.
