Description

Patented Feb. 24, 1931 PATENT OFFICE FRANK I. STRIGKLER, OF LOUISVILLE, KENTUCKY MEDICATEID TOBACCO AND PROCESS OF MAKING SAME Io Drawing.

This invention relates to medicated tobacco and process ofmaking the same, and it comprises more specifically the treatment of smoking tobacco for pipes, cigarettes or cigars with iodine, whereby the iodine may be effectively administered in the small amounts necessary for body metabolism and for the treatment of various infections of the respiratory organs, as well as thyroid disease, blood and glandular diseases, and numerous others.

Iodine has long been recognized not only as a powerful antiseptic, but also as having great eificacy in the treatment of numerous diseases. Tobacco lends itself extremely well as a vehicle for the administration of iodine to the human body, since, because of its heat in burning, the iodine which it carries is volatilized, and in its volatilized condition is inhaled.

In accordance with my invention, pure iodine crystals are heated in aclosed chamher to a temperature of from 110 C. to 120 C., this temperature being suflicientlyhigh to practically completely vaporize the iodine. The pure iodine vapor is then conducted to an air tight chamber containing the tobacco, which has been previously prepared by any well known method for use in pipes, cigarettes or cigars. The temperature of this second chamber is maintained at, or slightly below, room temperature (approximately 70 F.), thus permitting the iodine vapor to return to a crystal state, and in such state to be deposited upon the tobacco. After an exposure of from twenty-four to seventytwo hours the tobacco, now containing the iodine, is removed from the treating chamber and the iodine content determined by the iodine starch test. The treated tobacco is then blended with untreated tobacco until the desired blend and iodine content is obtained.

An alternative process consists in immersing the tobacco ina pure grain alcohol solution, which contains 25% iodine and 15% potassium iodide. The tobacco is allowed to remain in this solution for from twenty-four to seventy-two hours at slightly below room temperature, that is, somewhat under 70 F.

Application filed April 12,

1929. Serial No. 354,708.

At the end of this time the excess solution is drained off and the tobacco is dried for several days at a temperature low enough to prevent volatilization of the iodine which is intimately associated with it in crystalline form. The alcohol is, thus, completely evaporated, leavin the iodine deposited in the tobacco. As 1n the process first described, the iodine content is next determined by the iodine starch test and the treated tobacco is then blended with untreated tobacco to obtain the desired blend and percentage of iodine.

Having described my invention, what I claim is: i.

1. The process of medicating tobacco with iodine which consists in first converting iodine to a fluid state and, in such state, bringing it into contact with tobacco to be treated, and finally in crystallizing the iodine while in contact with the tobacco to thereby intimately associate it therewith.

2. The process of medicating tobacco with iodine, which consists in first volatilizing iodine crystals b heat to convert the iodine into vapors, an finally, in the presence of tobacco to be treated, re-crystallizing the iodine by reducing the temperature of its vapors, to deposit it upon the tobacco and thereby medicate it.

3. The process of medicating tobacco with iodine, which consists in heating iodine crystals in a closed chamber to the point of volatilization of the iodine, conveying the vapors so produced to a second chamber containing tobacco to be treated, and maintaining the contact of iodine and tobacco in said second chamber for from twenty-four to seventytwo hours at a lower temperature, thereby to cause re-crystallizationof the iodine.

- 4. The process of medicating tobacco with iodine, which consists in preparing a solution of pure grain alcohol and iodine, soaking tobacco in such solution at slightly below room temperature, draining off the excess of the solution, and finally drying the treated tobacco at slightly below room temperature to prevent volatilization of its iodine content.

In testimony whereof I allix my si nature.

FRANK r. s'rmoK'tER.
