Historical information

Thaddeus Fairbanks (1796 –1886) was an American inventor. of heating and cook stoves, cast iron ploughs, and other items. His greatest success was the invention and manufacture of the platform scale, which allowed the weighing of large objects accurately.
Fairbanks was born in Brimfield, Massachusetts, on January 17, 1796, the son of Joseph Fairbanks (1763–1846) and Phebe (Paddock) Fairbanks (1760–1853). His uncle was Ephraim Paddock, the brother of Phebe Paddock. In 1815 he moved to St. Johnsbury, Vermont, and set up a wheelwright's shop above his father's gristmill. In 1820 he married Lucy Peck Barker and In 1824 he built an iron foundry. his brother Erastus joined him to establish E. and T. Fairbanks, a partnership to manufacture heating stoves, cast iron ploughs a design for which he patented in 1826. In 1830 Fairbanks and Erastus became interested in the raising and processing of hemp. Fairbanks went on to patent a hemp and flax dressing machine and became the manager of the St. Johnsbury Hemp Company. He also built a set of scales that would measure large loads of hemp accurately, as there were no reliable scales at the time. Upon the success of building these scales, his brothers recommended that he make and sell these for general use. 
Fairbanks' most famous invention then became the platform scale for weighing heavy objects. These are commonly known as the Fairbanks Scales, for which he patented his original design in 1830.  Before this time, accurate weighing of objects required hanging them from a balancing beam as a result, particularly heavy or ungainly objects could not be weighed accurately. A platform scale, if large enough, could weigh an entire wagon. By placing a full wagon on the scale, unloading it, and then placing it on the scale when empty, it became possible to easily and accurately calculate the weight and value of farm produce and other loads. In 1834 Fairbanks and his brother formed "E. and T. Fairbanks and Company" to manufacture and sell these platform scales.
These scales were well known in the United States and around the world resulting in the company doubling in volume every three years from 1842 to 1857. There was a temporary slow down during the American Civil War, however, the business took off again after the war. Their partnership was incorporated in 1874 into a firm known as "Fairbanks Scale Company".

These platform scales revolutionized weighing methods of large loads and have been in use ever since. Portable platform scales are found in almost every hardware store, physician's office, and manufacturing factory throughout the United States and the world. The first railway track platform scale patent was granted to Fairbanks on January 13, 1857, as Patent No. 16,381. In 1916 the company was purchased by ”Fairbanks, Morse and Company”. Ownership of the company has since changed several times, but Fairbanks Scales continue to be made in St. Johnsbury Vermont to this day.
Fairbanks had received 43 patents in his lifetime with the last one at the age of 91. He died on April 12, 1886, and is buried at St. Johnsbury, Vermont, at the Mount Pleasant Cemetery.

Significance

An early example of the first type of platform scale that revolutionised the weighing of goods throughout the world made in the USA around the turn of the 19th century.

Physical description

Commercially built platform scale on wheels. Cast iron base supports iron weighing platform with wooden floor. At back, square hollow wooden post supports a hooded rod which bears the weight of the platform and which hooks onto a brass balancing arm, marked in pounds up to 50. There is a cylindrical sliding weight and on the end a loop for a metal weight holder. The holder is designed for three circular pieces of metal with a slit to the centre. The weights used are 50, 100 and 200 lbs.
