CANDLE.

11o Drawing.

My invention relates'to improvements in candles and more especially to that type of candles which burn with a colored flame.

An important object of my invention is to provide a device of the above mentioned character in which the flame is colored to correspond to the odor or perfume that the candle gives off when burning.

Heretofore it has not been possible to color the flames of ordinary candles consisting of paraflin, ceresin, etc., but I have discovered that with the use of inorganic wax, such as paraflin, combined with certain acids, such as stearic and palmitic, in .combination with certain chemicals, a candle ma be produced that will burn with a colored ame.

I contemplate adding aromatic oils and perfume bases to the candle in the process of manufacture in such manner that odor will be produced without smoke.

These candles will be colored to indicate the odor they will emit while burning, as for example, a candle that would give a lavender odor Wouldbe dyed lavender.

I also contemplate coloring the flame of the candle to indicate the odor to be emitted.

I also intend indicating the color of the flame of a candle by dyeing it that color.

For coloring the flame I intend using paraflin mixed with stearic acid agitated with air, which when mixed with certain chemicals will produce colored flames. The several chemicals that will give the candle flame the desired color will be mixed with the inorganic wax in the proper proportions (paraftin 75% and stearic acid or they may be incorporated .in aspecialiy prepared wick woven from long staple cotton to hold thc chemicals contained in solution in whichthe wick will be immersed, and then dried, the wick being largerthan the usual wick to permit it to absorb enough of the solutioncontaining the flame coloring chemicals to properly color the flame. In making the candle,the mixture of paraflin 75% and stearic acid 25% is melted, and when cool, but before ithardens, is agitated with compressed air which leaves the mixture light in weight and porous, allowing it toburn rapidly.

To obtain a red candle, red aniline dye is added-to the liquid Wax stearic acid mixture i and one-half ofone per centoil of rose geranium is also added at the same time. To obtain a red flame the wick which has been sat- Application filed January 30, 1925. Serial No. 5,902.

nitrate, 15 parts potassium chlorate, 4 parts antimony sulphate, and 13 parts sulphur, is placed in the center of a candle mold and the cooling m xture of paraffin and stearic acid, is then poured into the mold around the wick and cooled rapidly. In order to improve the color of the flame, 2 of a mixture of the dry chemicals spccilied above may be added to the paraflin and stearic acid at the time the aniline dye and the rose geranium oil are mixed.

I may use, for example, to obtain a blue colored flame, a combination of potassium nltrate 8 parts, liquid sulphur 4 parts, and copper sulphate at parts. The speciall PIG-I pared wick will be immersed-in a so ution (10%) of equal parts nitrate oflpotash and copper sulphate. The chemicals themselves will be mixedwith the candle base in suflicient amounts to get the proper color flame for example 2 as set out above.

To, obtain a red flame I may use strontium nitrate, 2 5 parts, potassium chlorate, 15 parts, antimony sulphate, 4 parts and sulphur, 13 parts, saturating the wick in a solution (10%) ofequal parts strontium nitrate and potassium chlorate.

The chemicals above mixed with the candle base (paraflin andstearic acid) and used for saturating the wicks are for producing the colored flames. The color of the candle itself will be made with aniline dye.

As, an example, a candle colored with purple aniline will contain essential oil lavender, which will diffuse odor as the candle is consumed, or a candle will be colored red with aniline and combined with essential oil rose geranium.

V These essential oils are very volatile and fragrant, being evaporated as the candle -bnrns. The heat generated by the burning will be produced without smoke.

It is to .be understood however that I do not restrict myself to these combinations of chemicals, or colors, but may resort to various changes without departing from the spirit of my invention or the scope of the subjoined claims.

Having described my invention what I claim and desireto protect by Letters Patcut. is: v

urated in a solution of 25 parts strontium 1. A candle having an' incense incorpo- 1 0 I the incense in the candle.

2. A candle of inorganic waxand a fatty acid, said candle havmg salts incorporated therein to produce a colored flame said candle being dyed the same color as that adapted to be imparted to the flame by the salts.

3. A candle of inorganic wax and a fatty acid, an incense incorporated in said candle, and salts incorporated in the candle and adapted to im art a color to the flame of the candle, sai color being known by a term which also designates the kind of incense in the candle,

4. A candle of inorganic wax and a fatty acid, saidcandle havin an incense incorporated therein, and sa ts incorporated in said candle and adapted to impart a color to the flame ofthe candle, said color of thc flame bemg known by a term which also designates the kind ofincense in the candle, said candle being dyed the color imparted to the flame by the salts.

In testimony whereof I afiix m signature. Y PHILIP K. UN KE.
