See history below:
In 1825, Thomas Ellicott built the first balance-beam platform scale in the world, for the New York Coal Co. Ellicott formed
Ellicott & Abbott
to manufacture his scales. By the mid-1840s the name had changed to
Abbott & Co.
Meanwhile, Augustus Ball Davis patented and built a series of scales covering a broad range of sizes. He operated under the name of
A. B. Davis & Co.
He, along with Charles M. Banks, also developed a line of machinery for testing materials such as iron bars, railroad rails, and concrete. And, most importantly for us, he designed and built a simple wooden-frame solid-chisel mortiser that used a foot pedal to advance the chisel. By 1865 Davis had sold his business, which became
Banks, Dinmore & Co.
The company's most important asset was their portfolio of patented designs, all due to Mr. Davis.
Frederick A. Riehlé purchased a minority share of the business in 1865. In 1866 or '67 Riehlé convinced his partners to acquire the assets of Abbott & Co., which was in financial difficulty due to mismanagement. In 1867, Frederick and his brother Henry bought out the other investors and changed the name to Riehlé Brothers. Henry died in 1890. In 1891, an anonymous competitor paid a large sum of money for Riehlé Brothers' scale business. They took away, and eventually destroyed, all stock and patterns. Riehlé Brothers continued in business with their line of materials testing machinery. In 1903 the business incorporated as
Riehlé Bros. Testing Machine Co.
