Object Details
- American Steam Gauge & Valve Mfg. Co.
- Description
- This nickel-plated instrument forms a U and is hinged around a brass measuring wheel and vernier. A cylindrical weight fits over a peg at the end of the pole arm. The plating has worn away from the handle for the tracer point. The tracer arm is stamped with a serial number: 5457. An oblong wooden case covered with black leather is lined with dark blue velvet. The top of the case is marked: AMERICAN (/) AMSLER POLAR PLANIMETER. A torn red and white sticker on the bottom of the case originally read: UNIVERSITY OF (/) CINCINNATI (/) 33894. Compare to 1981.0301.02 and 1981.0301.04; the serial number suggests this object is the youngest of the three instruments.
- The American Steam Gauge Company, a Boston firm, was founded in 1851, incorporated in 1854, and re-incorporated around 1902 with the name American Steam Gauge & Valve Manufacturing Company. According to the company catalog, James W. See, an Ohio engineer, designed the first Amsler-style planimeter in the United States, and by 1879 American Steam Gauge began manufacturing it as the American Amsler's Polar Planimeter. In 1896, it sold with the case for $15.00. In 1923 American Steam Gauge, the Hohmann-Nelson Company, and the American division of the Schäffer & Budenberg Manufacturing Company merged to form American Schaeffer & Budenberg Corporation.
- According to the accession file, this object was received by the Smithsonian in 1981.
