Schlichter, of Hamilton, Ohio, had patented a meat and vegetable slicer similar in design to the ubiquitous hand-cranked meat grinder that clamped to the edge of a table or counter. However, in 1920 he introduced an improved sensitive drilling machine, for which a patent was issued in 1924. A 1922 ad claims that he had been manufacturing sensitive drilling machines since 1892 but we have found no independent corroboration of that claim. He soon began manufacturing a clever ball vise of his own design. In 1892 Adolph Muehmatt of Cincinnati, Ohio, who had emigrated from Switzerland only the year before, began manufacturing engravers' supplies. Our interest is in the one established in 1926, which made made a sensitive drilling machine, a machine specialized for drilling small holes at high speed, and with a delicate touch so that the operator could avoid breaking the tiny drill bits. is a bit confusing because there was more than one company by that name.
