This steel maker was established in 1842. At some point around 1900, their name was cast into a drill press, presumably manufactured by them. They are still in business as a subsidiary of Inland Steel Industries, Inc.

Information Sources

• We learned of this company's drill press via a discussion in an owwm.org forum.
• The December 1922 issue of Engineering World has an article on the history of this firm. The article lists the metalworking machinery they manufactured: "Lathes, planers, shapers, drilling machines, milling machines, boring mills, grinders, hammers, friction saws, hack saws, punch presses, bending brakes, punches and shears, rotary bevel shears, bending rolls for angle and plate, flanging clamps, riveting machines, air compressors, flue shop equipment, spring shop equipment, nail machines, small tools, etc."
• From Volume 40 of International Directory of Company Histories, by Thomas Derdak and Jay P. Pederson, is a listing for this company. In 2000 their sales were $2.86 billion, and they had 4,500 employees. The following snippet was obtained through Google Books:

  Ryerson remained owner and head of the company until 1883, when another family member, Edward L. Ryerson, Sr., took over as owner, president, and chairperson. The founder's son, Joseph T. Ryerson, II, was also an active part of the operation. During this time, the company had pared its offerings to focus on serving boilermakers, which, at the time, were Chicago's primary users of iron and steel.

  Another snippet indcates that Ryerson was acquired by Inland Steel Co. in 1935.
