ABSTRACT:
A letter and number kit for use in preparing signs or names and addresses including street numbers. The kit consists of a packet of thin metal plates, each having upper and lower longitudinally and transversely extending score lines to provide segments having a blank on one or both faces or a letter, number, or punctuation mark on one or both faces of each segment. The number of letters in the kit may be varied. Primary letters of the alphabet which are used more frequently than other letters are present in the kit in a greater number than secondary letters which in turn are present in the kit in a greater number than tertiary letters. For instance, in comparatively large kits from approximately eight to eleven of each of the primary letters, from six to seven of each of the secondary letters and from approximately two to five of each of the tertiary letters may be present.
Means including special blades are provided to respectively cut upper and lower transversely and longitudinally extending indentations or score lines to divide the plate into rectangularly-shaped segments. In both operations, blades having opposed tapered cutting edges may be provided in both the upper and lower dies of the press for separately cutting both the longitudinally and the transverse score lines on indentations and while the press is set to provide oppositely disposed upper and lower score lines in the thin metal blades, stops are provided in the lower bed of the press to prevent the blades from severing the thin metal plates, thus limiting the depth of the opposed score lines or indentations of the blades.
Circular blades having tapered peripheries may also be arranged in opposed relation on a driving and a driven shaft or on driving shafts to provide upper and lower score lines or indentations in each of the metal plates.
