Riehle Brothers Machine CompanyAlso Known as Riehle Brothers Manufacturing and Riehle Cold Bend Co.Philadelphia, PA – Late 19th and early 20th centuries
The Riehle Universal Testing Machine at the smithsonian institute was manufactured in 1893 by Riehle Brothers Machine Company of Philadelphia. Apparently this company was also known in the industry ...as Riehle Cold Bend Co. as they did tensile testing, or the bending of steel until breaking in order to test its strength. Such a device is commonly referred to as a universal test machine or UTM.
In 1865 Frederick A. Riehlé along with other family members purchased a minority share of Banks, Dinmore & Co. along with its portfolio of patented designs, including a range of scales of various sizes and a line of machinery for testing materials such as iron bars, railroad rails, and concrete. Soon after, Frederick convinced his partners to acquire the assets of Abbott & Co., also a manufacturer of scales, which was in financial difficulty as a result of poor management. In 1867, Frederick and his brother Henry bought out the other investors and changed the name to Riehlé Brothers. Shortly after Henry’s death in 1890 a competitor paid a large sum of money for Riehlé Brothers’ scale business, allowing Frederick to focus on the testing products. In 1903 he incorporated as Riehlé Bros. Testing Machine Co.
Although the brothers were in the material testing business as early as 1865, a Norwegian-born American engineer and inventor named tinius olsen (1845 – 1932) is sometimes credited with the invention of the UTM. Olsen immigrated to the United States in 1869 and began working as a designer for William Sellers & Co. By 1872 he was employed by Riehlé Brothers as the firm’s superintendent and was the principal designer of Riehl’s testing machines during the 1870s. By the end of the decade friction was developing between Olson and the brothers and he was terminated in December of 1879. In 1880, Olsen patented a machine of his own design and started the Tinius Olsen Testing Machine Company to produce the device. Also located in Philadelphia, the companies competed into the twentieth century with both companies continuing to develop new testing technology.
