JOEL H. TATUM, OF NEW YORK, N. Y.

MANUFACTURE 0F CANDLES.-

Specification of Letters Patent No. 22,592, dated January 11, 1855;

To all whom 'it may concern:

Be it known that I, JOEL H. TATUM, of the city, county, and State of New York, have invented a new and useful Improvement in Candles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is an external view of a candle constructed according to my invention. Fig. 2, is a longitudinal central section of do.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists of an improved article of manufacture, viz. A candle having its stock composed of tallow, stearic acid and gum camphor, with or without bees- Wax, in about the proportions herein specified, and the exterior of the candle covered with a compound composed of stearic acid, gum camphor and gum damar, or equivalent iux, in about the proportions herein set forth.

To enable others skilled in the art to fully understand and construct candles according to my invention I will proceed to describe the process of manufacture.

The basis of the stock used is tallow, ordinary candle stock. To one thousand pounds of tallow I add Good tallow 50 lbs. Gum camphor 20 lbs. Stearic acid 20 lbs. lhite bees-wax lOlbs.

' 100 lbs.

To this composition may be added one pound of acetate of lead. This composition is fused together separately and added to the thousand pounds of tallow. The gum camphor and Stearic acid give solidity to the tallow and also increase greatly its illuminating power. The camphor however acts also as a flux and in connection with the wax render the tallow very limpid when fused, its viscidity being destroyed. The acetate of lead destroys or neutralizes any alkaline properties contained in the composition. The wax is an improvement and increases the illuminating power of ,the candle as well as acting in the capacity of a flux. Still the wax may be dispensed with,

and also the acetate of lead although they would be preferable.

In consequence of having the tallow rendered very limpid when melted, a slender wick may be used,-a plaited wick for instance, similar to those employed in wax and spermaceti. Pure tallow being viscid or thick when melted will not flow readily up in a wick, consequently in order to feed the ame properly, a thick wick must be used, and they require to be snuifed from time to time. The slender plaited wick however which I am enabled to use, see a, both figures, will as when used in the wax and spermaceti candles bend over as the candle burns and its end will be consumed in consequence of being in contact with the external air.

By having the tallow made hard or solid it fuses at a higher temperature and consequently may be dipped in an indurating composition to give it a hard exterior, which will not be liable to crack nor shell off. This indurating composition may be formed of TalloW 50 lbs. Stearic acid 4:5 lbs. Gum camphor 3 lbs. Gum damar 2 lbs.

1 06 lbs.

This composition is fused in proper vessel and the candles A, are dipped therein. The composition gives the candles a hard external surface b, which will not soften by being handled nor be materially aifected by the temperature of the weather.

I would remark that the candles may be either molded or dipped.

Having thus described my invention, what I claim and desire to secure by' Letters Patent, as an improved article of manufacture, is:

A candle having its stock composed of tallow, stearic acid, and gum camphor, with or without bees-wax, in about the proportions herein specified, and the exterior of the candle covered with a compound composed of stearic acid, gum camphor and gum damar, or equivalent flux, in about the proportions herein set forth.
