  • Patent number: 4380874
    Abstract: Methods for sign-making using dry transfer of letters from carrier sheets allow any of a number of different character sizes and row spacings to be provided. A carrier sheet bearing characters of a desired size is positioned relative to a carriage in dependence upon whether a row to be formed contains all upper case characters, or some or all lower-case characters. The carriage is movable smoothly in a horizontal direction to allow any desired horizontal spacing of characters, but movable vertically only in discrete increments. A plurality of row spacing indicators are positionable adjacent a sign blank to afford a preview of how characters of a given size having a given spacing will appear on a sign blank.
    Type: Grant
    Filed: April 27, 1981
