American Steam Gauge & Valve Manufacturing Company
The American Steam Gauge Company was established formally in 1851 and incorporated in 1854. Based in Boston, the firm produced all sorts of steam gauges and steam indicators, as well as Amsler's polar planimeter, safety valves, speed indicators, water gauges, whistles, revolution counters, and Seth Thomas and Howard clocks. It also made pyrometers, hyrdrometers, salinometers, mercurial siphon gauges, and steamship equipment.
By 1896, the firm had branch offices in New York and Chicago. Around 1902, the business took on a new name--the American Steam Gauge and Valve Manufacturing Company--and was reincorporated. It's home base was still Boston, but there were branches in New York, Chicago, Pittsburgh, and Atlanta.
