SELF-LUMINOUS SIGN.
Speclfl cation 0! Letters Patent.
Patented Mar. 5, 1918.
Application filed December 1, 1916. Serial No. 134,545.
T 0 all whom it may concern:
Be it known that I, HENRI MEYER, merchant, a citizen of Switzerland, residing at Geneva, Canton of Geneva, in the Confederation of Switzerland, have invented certain new and useful Improvements in Self- Luminous Signs, of which the following is a specification.
This invention relates to a self-luminous ign and particularly to that form of such signs provided with a radio-active material making the same visible in the dark. Heretofore as I am aware this radio-active material ha been employed in various manners, and the particular object of my present invention is the provision of a si in which the design is brought out strong y and consequently is readily observable in daylight as well as in the darkness. In carrying out this invention I preferably employ a suitable base plate on one surface of which there is provided a background, and on this background the design irres ective of its nature, is placed in white. overing the design made in white I employ any suitably radioactivematerial, and over the design thus formed I provide a suitable protective covering which may be a coat of thick varnish or a plate of transparent. material such as glass or transparent celluloid, in order that the design may be seen.
In the drawing:
Figure 1 is a plan of a luminous made in accordance with my invention.
Fig. 2 is an edge view of the same, and
Fig. 3 is a section on line 3-3 Fig. 1.
Referring to the drawing in carrying out this invention I prefer to employ a base plate 10 which may be made of metal or any other suitable material and on one surface of which there is provided a background 11. This may be made by providing this surface of the plate with a coat of dark or black paint or by coverin the surface of the plate in any other suita le manner. On this background 11 the design is made preferably in whitepaint. As indicated in the drawing the design is designated as Mr. John Doe, as indicated at 12. Covering the white design thus formed, i a layer of radio-active material 13 of any suitable composition and over this entire surface I then apply a thick coat of varnish 14 which as will be understood, is transparent and through which the design may be readily observable in the daylight as well as in the darkness, the white design making the same appear clearly against the dark background in the daylight and the luminous material serving the same purpose at night. As will be furthermore understood, the design thus formed may if desirable be covered with a plate of thin glass or transparent celluloid or any equally transparent material as an additional protection to the design.
I claim as my invention:
1. A luminous sign comprising a flat plate, a background of predetermined color placed on one surface of the plate, a design painted in white on the said background, and a radio-active material covering the said design.
2. A luminous sign comprising a base plate, a colored background covering one surface of the said plate, a white design on the said background, a radio-active material extending over the said design, and a cover of'transparent material extending over the thus treated surface of the plate.
3. A luminous sign. comprising a base plate, a colored background on one surface of the plate, a white design placed on the dark background, a radio-active material extending over the said design, and a coat of varnish covering this entire surface of the plate.
In testimony whereof I have afiixed my signature in presence of two witnesses.
HENRI MEYER.
