Description
The Hoskins Company was established in Chicago in the early years of the twentieth century. The firm moved to Detroit in 1908, and became Hoskins Manufacturing soon thereafter. The inscription on the horizontal cylinder of this device reads “HOSKINS ELECTRIC FURNACE / PATENTED IN U.S. AND FOREIGN COUNTRIES / U.S. PATENTS – FEB. 6, 1908 – MAY 14, 1907 – JULY 9, 1907 / TYPE FA 301 SER. NO 3145 / VOLTS 110 AMPERES 4.50 / HOSKINS MANUFACTURING COMPANY DETROIT / SOLD BY / ARTHUR H. THOMAS COMPANY / IMPORTERS AND DEALERS / MICROSCOPES, LABORATORY APPARATUS AND CHEMICALS / PHILADELPIA 17.”
According to trade literature, the Hoskins Type FA produced temperatures up to 1000° C and operated on AC or DC. There was also a Type FB that operated on AC only.
The referenced patents were issued to Albert Leroy Marsh (1877-1944), a metallurgist who, while working for Hoskins, developed a relatively inexpensive alloy suitable for making high-resistance wire that could be used in electric furnaces. In 1914, this alloy would be termed Chromel.
