LEATHER POLISH.

Ho Drawing.

To all whom it may concern:

. application, a brilliant and lasting gloss to shoes and other leather objects. Another object of the invention is to pro-l vide a polishing composition of the above described character in a convenient shape for its direct application to the leather, the elongate, cylindrical form commonly recognized by the name stick being best adapted for the purpose.

The stick of polish made approximately of the proportions of the well known sticks of shaving soap, may be wrapped in tinfoil or other protective covering but it is preferably enclosed in a casing provided with a means for its gradual protrusion.

In using the device, the stick is projected from the casing and its protruding end is rubbed upon theleather. The polish thus deposited in a thin layer of substantially uniform thickness, is subsequently rubbed to a gloss by means of a brush or cloth with more ease than in the use of liquids or pastes since the manner of application prevents the deposit of more polish than is needed to produce the desired gloss and insures its even distribution over the entire surface of the leather. a

The composition consists of a solid or semi-solid hydrocarbon, such as parafiin or tallow, which serves to provide a waterproof coating, a fatty substance, such as linseed oil which acts as a preservative and aids in the production of a mass of the desired consistency, a commercial base in solution, as for example, a solution of sodium hydroxide which neutralizes any acid or lime that may be present therein, a hard wax, preferably carnauba wax, water, and a dye material of the required color.

The following compositionof the materials in the given proportions has been found Application filed July 27,

1923. serial No. 654,153.

most suitable in the production of a .black leather polish of the required consistency:

Paraflin,20 grams.

Linseed oil, 5 cubic centimeters.

A 25% solution of sodium h droxide (NaOH) or sodium carbonate (Na O .05 cubic centimeter.

Carnauba Wax, 20 grams.

Nigrosine (oil-soluble), .05 gram.

Water, 250 cubic centimeters.

Nigrosine (water-soluble), .04 gram.

The mixture is produced by warming the parafiin to 100 (J- preferably in a water bath, then adding thereto the sodium solution and continuing heating until a smooth homogeneous mass is obtained. The carnauba wax is then added and the boilingcontinued until'the mixture is thoroughly saponified. At this point of the process, the oil-soluble nigrosine is mixed with the other ingredients by stirring and 250 cubic centimeters of water is added in small quantities. Finally the water-soluble nigrosine is dissolved in the remainder of the water and added to the mixture.

The composition thus prepared is placed in molds of the desired size and form and solidified by cooling. The sticks of the composite material are placed in suitable holders, such as that shown in the drawin and the-composition is applied to the leat er to be polished, by gently rubbing an end of the stick over the surface thereof.

The composition may be made for use of differently colored leather by substituting a dye of the desired color for the nigrosine. For example: creolin yellow or creolin orange, either separate or mixed together, is

suitable in preparing the composition for use on tan or yellow leather; creolin brown either separately or mixed with creolin 0range, for brown leather, -and scarlet creolin red for ox-blood leather. All these dyes are oil-soluble and are added to the mixture after having been dissolved in linseed oil.

The water-soluble nigrosine is used mere ly to give color to the water required in the a composition and thereby -add to-the staining quality of the composition, and it may be omitted if the ingredient is not readily available.

Water may be omitted from the composition by reducing the quantity of the carnauba Wax but the use of Water is preferable since it provides a solvent for parts of the solid or semi-solid ingredients not dissolved in the oil, and. since it promotes saponification and renders the mass more homogeneous.

What I claim ters Patent is:

1. A composition of matter adapted to form a semi-solid leather. polish comprising paraflin, linseed-oil, a, solution of sodium gydroxide, carnauba wax and an oil-soluble 2. A composition of matter adapted to form a semi-solid leather polish comprising paraffin, linseed-oil, a sodium hydroxide solution, carnauba wax, an oil-soluble dye,

water and a water-soluble dye.

3'. A composition of matter adapted to form a semi-solid leather polish consisting of paraflin 20 grams, linseed-oil 5 cubic cenanddesire to secure by Lettimeters, a twenty-five per cent sodium hydroxide solution .05 cubic centimeter, carnuuba wax, 20 grams, and an oil-soluble'dye.

4. A composition of matter adapted to mm a semi-solid leather polish consisting,

of puruflin 20 grams, linseed-oil 5 cubic cen-- timel'ers, a twenty-five per cent sodium hydroxide solution .05 cubic centimeter, 'carnauba wax 20 grams, an oil-soluble dye, and water 250 cubic centimeters. 5. A composition ofinatter adapted to form a semi-solid leather polish consisting of paraffin 20 grams, linseed oil 5 cubic centimeters, a twenty-five per cent sodium hydroxide solution .05 cubic centimeter, carnauba wax 20 grams, an oil-soluble dye, water 250 cubic centimeters, and-.1 Watersoluble dye.

In testimony whereof I have afiixed my signature.
