Abstract
Apparatus for sign-making using dry transfer of letters from carrier sheets allows 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 positioned 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.
Claims2
A coordinated plurality of carrier sheets which will assist an operator to make various signs using characters of a plurality of different nominal sizes, having different numbers of rows of characters and different vertical spacings between said rows, with use of a single sheet-positioning apparatus operable to position a sheet in incremental steps of distance d, each of said sheets carrying a plurality of transferable characters each having a baseline, the baselines of the characters of each respective nominal size on any sheet of said plurality of sheets being vertically spaced at integral multiples of said distance d, each of said sheets carrying means defining a reference line across the sheet, each lower-case character of any given nominal size on any of said sheets having its apparent vertical centerline located a vertical distance from the reference line on its associated sheet so that if successive ones of said sheets are installed in said machine with their respective reference lines similarly registered to the machine, the apparent vertical centerlines of the lower-case characters of all nominal sizes lie either on a common line or at an integral multiple of said distance d therefrom.
