Platform scale

In 1831, the first U.S. patent for a platform scale was issued to brothers Erastus and Thaddeus S. Fairbanks of St. Johnsbury, Vermont. Thaddeus invented and built it during the previous year, revolutionized weighing methods; earlier scales had been of the even-balance or steel-yard types. With the invention of the platform scale, the E. and T. Fairbanks and Company (which had until then been produced stoves, plows, forks, machines) began to specialize in manufacturing scales of all sizes. The business was successful, and grew to supply scales worldwide. On 13 Jan 1857, Thaddeus received the first U.S. patent for a railway track scale (No. 16381) which was introduced by their business. The company survives to the present day.
