identical set of original and intact early 19th century american antique industrial heavily reinforced turned and tapered cast iron platform and/or floor scale load-bearing columns likely manufactured by or for e. & t. fairbanks & co., johnsbury, vt. the slightly iron columns have been refinished and treated with a clear coat sealant to prevent surface corrosion. the robust fluted scale support (i.e., load-bearing) columns were salvaged from an old chicago factory. two brothers, thaddeus and erastus fairbanks founded the fairbanks scales manufacturing company in 1830 in st. johnsbury, vermont. thaddeus was a wagon maker by trade. he built a foundry in 1823 to manufacture two of his inventions - the cast iron plow and a stove. in 1824, erastus joined thaddeus to form the e & t fairbanks company in st. johnsbury, vermont. the brothers believed that the weighing systems of the time yielded inaccurate results. thaddeus attempted to produce a competitive device. through an arrangement of levers, thaddeus fairbanks was able to tremendously reduce the amount of weight needed to counterbalance a load. he then dug a pit for his lever design, placing the platform level with the ground. this modification ended the task of having to hoist the entire load. in his first design, thaddeus rested a platform on two long levers which were connected to a steelyard, upon which the counterbalance was placed. although achieving accurate weighing results, instability of the design was troubling. by adding two short levers to his long ones, he established support points at all four corners of the platform. now his scale was not only accurate, but very stable. in 1830, thaddeus built his first real scale and applied for a patent. by the time of the civil war, fairbanks' scales were the best known american product in the world. erastus and thaddeus were now joined by their younger brother, joseph. the modest one-building operation expanded to 40 buildings by 1910. e & t fairbanks & company offices opened in the cities of boston and new york in the 1870's. by 1882, more than 80,000 fairbanks scales were produced annually. by 1897, the company held 113 patents for improvements and inventions in weighing. fairbanks offered its customers 2,000 standard model scales, yet made as many as 10,000 different models and custom systems. priced for the pair.
