UNITED STATES PATENT OFFICE.
CARL DELLIVIK, OF ROGERS PARK, ILLINOIS.
PROCESS OF TINTING INCANDESCENTS.
SPECIFICATION forming part of Letters Patent No. 450,960, dated April 21, 1891.
Application filed December 20, 1 8 8 9.
T0 on whom it may concern:
Be it known that I, CARL DELLWIK, a subj ect of the King of Sweden, residing at Rogers Park, Cook county, and State of Illinois, have invented a new and useful Improvement in the Process of Tinting Incandescents, of which the following is a specification.
Heretofore many incandesoents which have been practically used for the purpose of creating and disseminating light by means of gas-flames have been made of magnesia, lime, lanthan, zirconia, and other earthy oxides, most of which disseminate a white light. It is at times very desirable that the light given by such incandescents shall be colored or tinted, so as to satisfy the requirements of all uses of such means of lighting. Attempts have heretofore been made to effect such coloring or tinting by mixing the coloring material with the substance of which the incandescents were formed; but such attempts have not been satisfactory.
The object of my invention is to provide a method by which the incandescents can be so treated that they will give such tinted or colored light and will not be open to any of the many objections which defeat the purpose of mixing the coloring-matter with the materials of which the incandescents are formed.
I have found by actual practice that the mixing of the substances employed by me with the materials ofwhich the incandescents are formed has developed entirely other and different results from those produced by the method of treatment whichI have discovered; and that while the properties of the same materials used by the method which I have discovered are Valuable, when the coloringmatter is mixed with the material of which the incandescents are formed the same properties become entirely valueless. This state of facts is founded upon a sound scientific basis, for the substances so used for coloring are almost uniformly conductors of heat, whereas the body of the incandescents must be formed Serial No. 334.450. (N0 specimens.)
of non-conductors and must be very refractory, else they could not endure the heat necessary to render them luminous. \Vhen, therefore, the conductor is mixed with the nonconductor, the composition resulting has such a character that it conveys the heat instead of confining it, and the incandescents do not become sufficiently heated to furnish the desired light.
To carry myinvention into effect I take the incandescent after the same is otherwise ready for ordinary use and I paint, coat, or cover the same with a solution of the coloring-matter, so that it shall surround and envelop the material of which the incandescent is composed. I then so arrange and dispose the said incandescent thus treated that the said coloring-matter shall not be disturbed until the same becomes thoroughly dry. The said incandescents so treated and dried are then subjected to such a high degree of heat that the volatile substances therein are expelled and the coating or covering is thus reduced to such a condition that it will endure as long as the incandescent shall be useful.
The coloring-matter will vary with the color desired, as follows: To produce a yellow light I prefer chromium or cobalt. To produce a. red light I prefer copper, platinum, and iridium.
Other well-known materials may be used for producing other colors.
Having described my invention, what I desire to secure by Letters Patent is- The herein-described process of tinting or coloring incandescents, which consists in painting or coating them with a coloring-matter, drying them when so coated, and then subjecting them to a high degree of heat, substantially as described.
CARL DELLWIK. \Vitnesses:
JOHN JENKINS, J r., ALFRED LocKwoon BROWN.
