TABLETVEOR use IN REMOVING HAIR.

SPECIFICATION forming part of Letters Patent N 0, 330,716. dated November 17, 1885.

Application filed June 24, 1885. Serial No. 169,690.

,To allwhom it may concern.-

Be it known that I, SAMUEL RIDewAY KENNEDY, of Philadelphia, in the county of Philadelphia,and in the State of Pennsylvania, have invented certain new and useful Improvements in Tablets for Use in Removing Hair; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1. shows a perspective View of the tablet, and Fig. 2 a transverse sectional view of the same.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide a new article of manufacture; and to this end my invention consists in the tablet composed of a substance or compound for use in removing hair, covered with a protective coating adapted to keep out moisture and air, substantially as hereinafter described, and more specifically pointed out in the claims.

In the drawings, A designates the tablet, which consists of the main portion B, covered by the film or coating 0.

I use the substance and compound described and covered by the claims in the application No. 157,499 filed by me. Such substance and compound, as set forth in that application, consists of a sulphide of an alkaline base, as sulphide of barium or sulphide of calcium, in conjunction or mixed with a starcl 1, resin, gum-mastic, or equivalent dilutants.

In order to keep this substance or composition for use in removing the hair, as described, inert and unchanged until it is desired for use, it is necessary to protect it from air, moisture, and oxidizing influences. In order to do this most completely while having the compound in the most convenient form for use, I make up the composition into tablets by compression and then coat each tablet with an air and water proof coating or film. Each tablet is of a size just sufficient for an ordinary shavethat is, for the removal of the hair from the face. Where only enough .of the composition toremove the hair from a (No model.)

portion of the face is desired, of course the tablets can be made correspondingly smaller.

If, as has heretofore been done, it be attempted to keep the hair-removing substance in the quantity and not made up into tablets with protective coating, as set forth herein, the substance will deteriorate rapidly on account of the unavoidable access of air and moisture when anyof the substance is taken for use.

As put up by me in tablets covered with the protective coating, a sufiicient quantity of the composition can be taken at any time without disturbing or exposing the rest of the material or composition.

The tablets can be stored away'or carried about without danger of deterioration, or of their injuring anything with which they come in contact.

The compound or substance may, as desired, be molded or pressed into cakes or tablets while moist or in the dry state. Even if the particles should not tend to cohere very strongly, the protective coating put on would hold them together. I prefer to make this coating of some soluble'substance which will make a film capable of resisting and keeping out the air and moisture usually contained therein, and so insuring the protection of the contents of the cake from oxidizing influences, but will be easily dissolved when the cake or tablet is placed in water. I

l contemplate using for the coating some soluble varnish or parafifiine or wax; but do not intend to limit myself to any material therefor.

As most if not all the agents heretofore known or used for or in removing the hair are materially affected and deteriorated by air and moisture, it is obviously of very great advantage to put them up, as I contemplate doing, in the form of coated tablets or cakes. 0

The composition which I prefer contains a sulphide 'of an alkali basesuch as sulphide of barium, sulphideof'calcium, sulphide of iron, or sulphide of potashjas the active agent,

mixed with starch, resin, gum-mastic, or their 5 equivalents.

Of these suggested compounds I prefer the one consisting of sulphide of barium in conjunction with starch.

Having thus described my invention, what I claim is 5 l. A tablet composed of a quantity of sulphide of an alkaline base mixed with starch, and covered with a protective coating, substantially as and for the purpose described.

2. A tablet consisting of sulphide of barium 10 mixed With starch or, other dilutant and coated with a protective covering, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of June, A. D. 1885.

S. R. KENNEDY.
