Application May 7, 1934, Serial No. 724,406
bodiment, by the accompanying drawing, in'
which- Figure l is a plan view of a sign embodying my invention; Fig. 2, a plan view of the printed paper core which is employed; and Fig. 3, a sectional view, the section being taken as indicated at line 3 of Fig. 1, and the parts being shown as assembled prior to the heating and pressing operation.
In the illustration given, a paper core comprising a thin strip of paper having printed thereon the inscription of the sign is enclosed between two thin sheets of celluloid. For example, the celluloid sheets may be .020 of an inch thick. The paper and celluloid strips are then placed between two glass panels. Pressure and heat are then applied to integrate the celluloid and paper and the spaces between. the plates at the border are filled with a thin layer of sealing compound. The sealing compound is a well known adhesive water-tight material which hardens' after it has been applied to the edges of the glass. For the purpose of illustration, the paper and celluloid layers shown in Fig. 3 are much exaggerated in thickness. In actual practice, the integrated sheet and celluloid layers are extreme ly thin compared with the thickness of the glass.
The paper strip may be of a thin translucent stock such as, for example, tissue paper, glassine, etc. In the illustration given, the paper is provided with perforations l0 which are distributed paper sheet can be employed which extends substantially to the border of the glass; i. e., substantially up to the layer of the sealing compound. On the application of heat and pressure, the edges of the glass panels do not break, the 5 celluloid tending to flow into the perforations and thus reducing the thickness of the composite celluloid and paper layers. By thus making it possible to employ a paper strip running substantially to the edges of the glass panels, there 10 is substantially no waste of space, and large letters or inscriptions can be formed on the signs with substantial areas oi! frosted glass background about the letters or other inscriptions. By avoiding a border of clear glass between the 15 outer edge of the glass and the paper sheet, I find that the letters stand out on the frosted background more clearly in daylight and also more clearly at night under the illumination of a street light.
The glass sign is weatherproof and may be supported without further framework in a position where it is directly exposed to the weather. If desired, it may be supported in metal frames such as are in common use.
While the invention is particularly applicable to street-name signs, it will be understood that it may be used in connection with other signs, displays, etc.
The foregoing detailed description has been 30 given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
1. In a sign of the character set forth, a translucent cellulose sheet, sign inscriptions thereon, translucent sheets of celluloid enclosing said cellulose sheet and integrated therewith, glass pan- 40 els enclosing said composite cellulose sheet and celluloid, said cellulose sheet being provided with perforations, and a sealing compound closing the space between the panel edges.
3. In a sign of the character set forth, a lightpermeable cellulose sheet, sign inscriptions thereon, translucent sheets of celluloid enclosing said cellulose sheet, said cellulose sheet being provided with spaced perforations throughout, glass panels enclosing said celluloid and cellulose sheets, said cellulose sheet and celluloid be-- ing integrated, and a sealing material closing the space between the edges of the panels.
3. In a sign of the character set forth, a lightpermeable cellulose sheet. provided with spaced perforations, sign inscriptions thereon, translucent sheets oi. celluloid enclosing said cellulose sheet and integrated therewith, glass panels enclosing said celluloid and cellulose sheet, said cellulose sheet being perforated and extending substantially to the edges 01 the panels, and a sealing compound closing the space between the edges of the panels.
4. In a sign or the character set forth, a light- 1 permeable cellulose sheet, sign inscriptions thereon, light-permeable sheets of celluloid enclosing said cellulose sheet and integrated therewith, glass panels enclosing said composite cellulose and celluloid and extending beyond the edges of said composite sheet, said panels having their edges in alignment, and a sealing material enclosed between said panel edges and being or substantially the same thickness as said combined cellulose and celluloid sheets.
