Platform Scale

Fairbanks, Thaddeus · 1832

Erastus and Thaddeus Fairbanks, both of St. Johnsbury, Vermont, obtained two U.S. patents on June 13, 1831, both describing “an Improvement in the Machine for Weighing Heavy Bodies, usually called the ‘Platform-Scale’.” These patents were canceled because of defective specifications, and new ones granted, on March 6, 1834. These patents, in turn, were canceled because of defective specifications, and newer ones (#118 and #119) were granted on February 10, 1837. The model shown here pertains to one of these later patents.
