HARRY BARRINGER COX, OF CHICAGO, ILLINOIS, ASSIGNOR TO TRUMAN G. PALMER, OF CHICAGO, ILLINOIS.
INCANDESCENT GAS-LAMP.
Specification of Letters Patent.
Patented Dec. 26, 1905.
Application filed December 13, 1904. Serial No. 236,660.
Be it known that I, HARRY BARRINGER COX, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Incandescent Gas-Lamp, of which the following is aspecification.
The invention relates to incandescent gaslamps, and seeks to provide a simple means for modifying the color of the light emitted therefrom.
The exact nature of the invention is set forth in the following description and particularly pointed out in the appended claims.
The common incandescent gas-lamp now in use comprises aburner of the Bunsen type and producing a self-burning mixture of air and gas and a mantle of a suitable infusorial earth interposed in the flame of the burner and heated to incandescence thereby. The bare Bunsen flame is non-luminous or emits onlyalittle light of abluish tinge. The light from the mantle heated to incandescence in the Bunsen flame is laring and brilliant bluish-white in color and for that reason objectionable for illuminating purposes. In this light there are few of the yellow and red rays of the spectrum. Attempts have been made to produce asofter yellow light by constructin mantles of different earths; but as yet suc attempts have not met with marked success. I have found that by introducing a suitable mineral salt into the flame of the burner the color of the light emitted from the mantle may be satisfactorily modified and a soft yellowish light of great diffusive power produced.
In the drawing is illustrated one form of lam to which the lpresent invention may be app ied.
The Bunsen burner for producing the selfburning mixture comprises a base-piece 10 and the tubes 11 and 12. The base-piece 10 is adapted to be secured on a gas-xture or otherwise provided with means whereby it may be supplied with gas and is provided with a gas-inlet nozzle 13. Tube 11 is fixed at its lower end to the base-piece 10 and is provided with air-inlet orts 14. Tube 12 fits over the contracte upper portion of the tube 11 and is expanded at its upper portion to form a mixingchamber 15. A cap comprising a gauze piece 16 and a sleeve 16 is fitted over the upper outlet or 'ignition portion of the burner. Metal disks 17 and 18 are fixed centrally upon the gauze cap, and a central depressed ortion in the disks 19 forms a socket into w ich the lower end of the mantle-supporting stem or rod 2O is inserted. The mantle 21, of suitable infusorial or other earth, is suspended from the upper forked end of the supporting-rod 20. The gas and air from the nozzle 13 and parts 14 are mixed within the tubes 1,1 and 12 and .in the chamber 15. The self-burning mixture thus formed when ignited burns above the gauze cap and heats the mantle -suspended at the upper outlet end of the burner to incandescence.
The parts thus far described are well known and may be widely varied without departure from the essentials of the invention.
Numerous substances, such as the salts of the alkali metals and of the alkaline earths, will impart color to a fiame, and I have found that these salts may be satisfactorily employed in the Bunsen flame of an incandescent lamp to modify the light of the incandescent mantle, which, as stated, is normally a glaring bluish white. Numerous substances may be employed in accordance with the present invention-such as the salts of potassium, sodium, lithium, calcium, strontium, and barium-and these may be employed to differently modify, as desired, the blue-white color of the incandescent material. It should be noted, however, that the non-refractory compounds of these metals should be employed-fi. e., such compounds as may be volatilized or broken up by the heat of the iiame. The refractory compounds or substances will not give the characteristic coloration and will not have the marked effect in modifying the White light of the mantlecontemplated by the present invention. When sodium and calcium salts are interposed in the flame of the lamp within the mantle, a soft yellow light is roduced. Strontium salts will impart a re dish and bariumv salts a greenish tinge to the light. For ordinary illuminating purposes I prefer to use a non-refractory or volatile sodium salt and have obtained best results with silicate of sodium or water-glass, which when introduced into the flame of the burner will change the usual blue-White li ht of the mantle, so that a brilliant soft ye lowish light of great diffusive power will be produced. Preferably the silicate of soda or other salt is interposed in the path of the burner-flame within the mantle and is also preferably mixed With abody of infusorial earth or `other suitable binding material which will withstand heat and which will prevent the too rapid disintegration or volatilization of the coloring substance.
The arrangement of the body of color-modifying substance Within the mantle is quite important, for if placed on the mantle itself or mixed with the material of which the mantle is formed the light will be considerably cut down, the mantle will be weakened by the disintegration of the light-modifying substance, and its life thereby considerably shortened, and, moreover, on the mantle the light-coloring substance would be exposed over a large area to the ilame of the burner, and the desired effect would soon be lost.
In practice of the invention the silicate of soda and other salt is mixed with a suitable binder, preferably finely-ground infusorial earth to the consistency of mortar. The mixture is then mounted in any suitable manner within the mantle 21 and in the path of the flame from the Bunsen burner. Preferably, however, the mixture is formed to disks 22 upon the stem or support 2l for the mantle, as indicated in the drawing.
A device thus constructed of sodium silicate and infusorial earth has been found to impart to the mantle of an incandescent lamp the desired yellow color for mantles, although there is a very slow disintegration of the sodium silicate.
It is obvious the numerous changes may be made in the color-modifying means and manner of applying the same Without departure from the essentials of the invention as set forth in the claims.
By the word volatile as used in the claims is meant a substance that will slowly volatilize at high temperatures.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
l, An incandescent lamp comprising a Bunsen burner, an incandescing mantle therefor and a separate body of suitable mineral salt arranged inside of the mantle in the path of the burner-flame for modifying the color of the light from the mantle, substantially as described.

6. An incandescent lamp comprising a Bunsen burner, an incandescing mantle therefor, a central support for the mantle arranged within the same and mounted on the burner and disks formed of a mixture of silicate of soda and infusorial earth, mounted on the mantle-support, substantially as described.
