Description: |
| This is an improvement to the Bourdon steam gauge of patent 9,163. We know that this patent was used by American Steam Gauge Co. of Boston because "T. W. Lane's improvement" to the Bourdon gauge in mentioned in an 1860 announcement that American Steam Gauge Co. was merging with National Steam Gauge Co. (in fact, American was buying out National). An 1877 ad for American Steam Gauge Co. features a gauge that says on the face, "American Steam Guage Co. / Boston. / Sole Proprietors & manufs. / of the / Bourdon / Steam Gauge. / T. W. Lane's Improvement. / Patented Feb 22d 1859." |
