Illustration of type cases

Not unlike letterpress cases for the sighted, these cases for the blind were organized according to letter, case (upper or lower), signs, accented letters, figures, etc. They were set at a forty-five degree angle so that the letters would not move unintentionally. To ascertain if a letter was upright, the blind printer would drag the stem of the character along the printer; if the notch on the character did not catch on the printer's notch, it was correctly positioned.
