About this work
This patent model demonstrates an invention for a machine to smooth the sides of type; the invention was granted patent number 631. In the inventor's opinion, this foot-driven machine allowed the operator to rub around sixty thousand types in a day, in conditions of less "unhealthiness" than the usual. The model is missing its treadle.
