To all whom t may concern.' y v Be it known that I, vETHAN I. Dones, a citizen 0i' the United States, and a resident of Pittsburvh, in the county of Allegheny and y State of ennsylvania, have invented certain new and useful Improvements in Illuminating Devices and I do hereby declare the fol# i lowing to be a full, clear, and exact description of the `vinvention;` such lasl Will'f'en'able tains tomake and use the'same.
others skilled in the art to which appr/ rify `by light from a primary source and remain luminous-after the primary light shall have been extinguished and thus afford a mild light .which may be maintained with great economy of eleotricity'or other source by i means of which the .l provided. i
` siasi l is invention, and 'Fig "gmodiiicationf i .1), vl -represents` a 'lamp fixture of-the; usually employed 'for-` tlie lamps of autom-'l.f Toiles, An incandescent electric lamp -2 may L be suitably `mounted 'n the lamp X Gand 'cormeCted-ipg `circuit with a-suitablel bat 'f ftery and ,svviiiohdevice not' shown.

In the construction shown in Finnlf'4 applied' as a coating to' the inner face of .One of saidYdiaphragms.n j
these plates or diaphragme are made dishshaped with their cross-sections presenting long arcs. These plates or diaphragme are Y so relatively shaped that when placed one within the otherand With their peripheral` edges contacting (and fused i-f'desiredla 'y space 5 Will be provided between ythem.,V
The plates or diaphragms 3 and 4 may be of clear glass and transparent or V'one or both of them may be madev of colored or tinted of ground glass.
The inner surface of the outer' plate (or Havin@r o'fsaid' lamp.

glass and desired the outer plate ordiaphragm or even the inner one may be made the outer surface of the inner, plate, if deslred) is provided with a'. 'coating of ,phos- `phorescent material. Whichy willabsorb and retain light for a. 4considerable period .and
-Which will be activated to renderl it luini-v nous bylight rays-from thepelec'tric lamp,
f `which flatter may be flashed at suitable in- 'ftervals forvthis purpose. :The material 4of :which the .coating is composed may'consist, orjfexample-of zinc' orlcaloiumsulid and preferably a. very y.small amount of radio- Hl ln the Storni. of the device ,shown in Fig. slightly concavo-f active material, such as a' salt of radium.
