Description:
This drill press is intended for "perforating compiled sheets of paper." The 1913-04-24 Geyer's Stationer magazine mentioned the newly introduced paper drill from Samuel C. Tatum Co.: "The new paper drill has a transversing table and runs at the rate of 1,500 revolutions a minute, thus saving 80 per cent in time and labor." According to an article on this paper drill in a 1915 issue of Inland Printer, the manufacturer had just introduced a multi-spindle version.
