Ryerson Drill press

According to Vintagemachinery.org, "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." 

A quick google search finds they also built large lathes, milling machines and other machine tools.
