UNITED STATES PATENT OFFICE.
WILLIAM MAHLER, OF NEW YORK, N. Y.
INCANDESC ENT-LIGHTING SUBSTANCE.
SPECIFICATION formingpart of Letters Patent No. 606,726, dated July 5, 1898.
Application filed July 31, 1897. Serial No. 646,704. (No specimens.)
T0 ctZZ whom it may concern.-
Be it known that I, WILLIAM MAHLER, a citizen of the United States, residing in the city, county, and State of New York, have invented av newand useful Improvement in Incandescent-Lightin g Substances, of which the following is a specification.
My invention relates to improvements in the manufacture of incandescent-lighting devices, such as are used for the well-known incandescent gas-light, in which is used a hood, frame, or mantle made up, primarily, of a fabric of cotton threads or the like and impregnated with a solution of the salts of infusible earthy oxids. This prepared fabric is then subjected to heat, which consumes the foundation or primary fabric and leaves a skeleton body consisting of the infusible earthy oXids resulting from the decomposition of the salts employed in impregnating the fabric.
My invention consists in an improved compound for impregnating the hood, frame, or mantle before described; and the object of my invention isto produce an intensely brilliant light of an orange color.
. 'It has been found that the combination of thorium oxid with a small percentage of cerium oxid, a combination known in the art, results in a light of great brilliancy of almost pure white. There are many reasons why a very white light is not desirable. In the first place, it is veryhard on the eyes. In the second place, it produces a very ghastly eifect on the human countenance. I have discovered that the addition of a very small percentage of neodymium oxid to the above-dethorium oxid; one per cent. of cerium oxid,
.5, per cent. of neodymium oxid, the essence of my invention being the addition of such small percentage of neodymium oXid to a combination of thorium and cerium oxids as shall result in the production, when burned to incandescence, of a soft orange-yellow light the color of which will not deteriorate and the brilliancy of which will not be decreased.
What I claim is 1. A mantle or hood forincandescent lighting, composed of a large percentage of thorium oxid, a small percentage of cerium oXid and a percentage of neodymium oxid considerably smaller than the percentage of cerium oxid, substantially as specified.
2. Amantle or hood for incandescent lighting, composed of. about ninety-eight and onehalf per cent. (98%%) of thorium oxid, about one per cent. (1%) of cerium oxid and about one-half of one per cent. (7% of 1%) of neodymium oXid, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WVILLIAM MAHLER. Witnesses:
