LAMP.
Specification of Letters latent.
Patented Aug. 19. 191%).
Application filed July 25, 1917. Serial No. 182,741.
To all whom it may concern:
Be it known that I, Err-IAN I. Donns, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in lamps,the object of the invention being to provide a lamp structure in which the illumination shall be derived from material therein, having the property of absorbing and then emitting the light so absorbed; to so construct the lamp that the activity of the illuminating material may be replen ished periodically, and to construct the lamp in such form that it shall be compact and so that the illuminatin material shall be so disposed that it wil project its light emanations downwardly and thus serve the double purpose of a light giving medium and reflector for the emitted light.
With this and other objects in view, the invention consists of certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.
In the accompanying drawings; Figure 1 is a view partly in elevation and partly in section showin an embodiment of my invention, and Figs 2 and 3 are views showing slight modifications.
1 represents a globe having a general flattened form and comprising two bowl-like members 23 of glass or other transparent material. These bowl-like globe members are provided with peripheral flanges 45 respectively which lie parallel w1th each other and are encircledby a ring 6. In the form of the invention shown in Fig. 1, the ring 6 is provided at its lower edge with a flange 7 which underlies the flange 5 of the lower globe member 3, and thumb screws 8 passing through the ring 6 at intervals, overlie the flange 4 of the upper globe member 2, and thus the two globe members are removably connected together.
Instead of arranging the connecting rin 6 as above described, the osition of sai may be reversed, so '0 at its flange 7 rin will overlie the flange 4 of the globe member 2 and the thumb screws 8 underlie the flange 5 of the lower globe member 3, as shown in I'ig. 2, or, if desired, the eripheral flanges 45 of the two globe mem ers may be fused together as illustrated in Fig. 3.
The upper globe member 2 is made with a central opening 9 to facilitate the entrance of an incandescent electric lamp 10 or other source of artificial light, and a flaring flange 11 surrounding said opening serves to recelve thumb screws 12 passing throu h the flange of a ring 13 secured to the casing 14 of the incandescent lamp structure 1 being thus suspended from said lamp structure.
a salt capable of becoming lumlnous upon exposure to either artificial or sun-light,
such for example as zinc or calcium sulph1d,and said material may also comprise a radioactive material which will enhance and intensify the luminous activity of the sulphid salt,such for example, as a salt of radium.
Any suitable means may be employed to llght the incandescent lamp periodically to enl ven the activity of the luminous light g1vmg coating 15.
Experience has demonstrated the fact that my improvements provide means whereby a cold light may be provided which will give ample luminoslty in a room to permit the occupants to read or to perform any duties for which a soft and moderate light may be required. 7
It is especially useful in the cabins of ships, particularly submarines, where a mild light is desirable, and where economy in the use of the electric current for lighting purposes is an important factor. My improved lamp may also be used to great advantage on automobiles or railway cars, both for interior lighting and for head-light puroses.
Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is
1. Illuminating means, comprising a flattened lobe having the upper portion thereof coate with phosphorescent material which will emit light and also reflect the same through the lower portion of said flattened globe, said material constituting the principal light giving element of the lamp, and a source of artificial light within the globe for activating said phosphorescent material in the upper portion thereof.
*2. Illuminating means, comprising two disk-shaped members, a flanged ring engaging one of said members, screws carried y said ring and engaging the other of said members, said members forming a flattened globe, a phosphorescent coating 1n the upper member and constituting the principal lightgiving member of the lamp and also constituting means to reflect the light. through the lower member, and a source of light between said members for activating the phosphorescent coating. 7 p
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
