This printing press was modified to emboss entire pages of braille at once, allowing for the mass-production of documents. Since braille is read by feeling raised dots, those dots need to all be the same size and height. The press is designed such that the bed and platen are parallel just prior to and during impression which means that the pressure is both strong and the same across both pages. In service until 1982, it was the last such press used by CNIB to print braille.

Notice the John Thompson Press Co. trademark colt which is cast into the two sides of the machine frame.
