UNHTED STATES MYRON LASKIN, OJF MILWAUKEE, WISCONSIN.
METHOD OF TANNING AND FINISHING SKINS.
No Drawing.
This invention relates to improvements in method of tanning and finishing skins, and more particularly with relation to tanning shearlings or wool skins.
It is one of the objects of the present invention to tan, color and finish the flesh side of hides and skins which still have the fur, hair or wool on in a manner which will provide a finish similar to the finish on the grain side of ordinary leather, thus producing a new article of manufacture.
A further object of the invention is to rovide a method of tanning and finishing s ins and more particularly shearlings or wool skins in which the flesh sides of the skins are colored and finished to look like the grain side of the skin, to eliminate the use of linings in garments or other articles manufactured from the skins.
A further object of the invention is to pro Vide a method of tanning and finishing skins having the fur, hair or wool thereon, which is very simply and easily carried out to produce a finished and desirable product as a new article of manufacture.
With the above and other objects in View, the invention relates to the improved method of tanning and finishing skins which is well adapted for the purpose described.
While the method will be described with relation to a piece of sheepskin, it is to be understood that the method is also applicable for finishing the flesh sides of tanned fur skins, lambskins, and all hides and skins tanned with the hair or W001 011, and other hides and skins in which the hair or wool has been removed.
In carrying out my improved method, the skins, with the fur wool or hair on, are first tanned in the ordinary manner, and then carefully buffed on the flesh side. A bottom dye coat of aniline or vegetable dye is then applied to the flesh side, and if the former, preferably the following ingredients are used, and approximately in the following proportions: fourteen (14:) grams directaniline black dye; eight (8) ounces gum tragacanth solution (2 oz, gum tragacanth per gal. water) one (1) quart water.
The skin is then hung to dry, and when dry, a pigment finish coat is then applied to the flesh side. Said pigment coat is formed from the following ingredients, and approximately in the following proportions:
Eleven (11) liquid ounces beeswax solution (carnauba wax solution) ;sixteen (16) liquid Application filed October 1?, 1927. Serial No. 226,818.
ounces aqueous shellac solution; twenty-seven (27) liquid ounces aqueous solution of casein, albumen and shellac; two (2) liquid ounces oil of mirbane; fifty-two (52) liquid ounces prepared blood; fourteen (14.) liquid ounces lamp black; thirty-six (36) liquid ounces water; one and one-half (1 gallons water.
The coated skin is then hung to dry, and when dry a top coat finish is then applied to the flesh side, consisting of the following ingredients, and approximately the following proportions: eight (8) liquid ounces aqueous shellac solution; eight 8) liquid ounces aqueous solution of casein; sixteen (16) liquid ounces water.
The coated skin is then hung to dry, and when dry is given a final glazing or polishing operation on a suitable machine.
When thus completed, the flesh side of the skin has a finished surface, and the skin can be made up into garments, gloves or footwear of a single thickness, due to the finish of the flesh side of the skin.
It is to be understood that the flesh side of the skin may be colored any shade desired, and the surface finish may be a dull or lustre, or hard or soft finish, without departing from the-spirit and scope of the invention.
It will also be further understood that in providing the different finishes and colors, dye stufi's and ingredients other than mentioned may be used in connection with this process without departing from the spirit and scope of the invention.
From the foregoing description, it will be seen that the method of tanning and finishing skins is well adapted for the purpose described, and produces, as an article of manufacture, a skin or hide having a finished appearance on both sides.
WVhat I claim as my invention is:
1. Method of tanning and finishing skins, which consists in tanning a skin in the ordinary manner, then butfing the flesh side of the skin, then applying a bottom dye coat to the flesh side and then drying the skin, then applying a pigment finish coat to the flesh side of the skin and again drying the skin, then applying atop coat finish to the flesh side of the skin and drying the same, and then when dry finally glazing or polishing the flesh side of the skin to produce a skin having a smooth finished appearance on its flesh side.
2. Method of tanning and finishing skins, which consists in tanning a. skin in the ordinary manner, then bufling the flesh side of the skin, then applying a bottom dye coat of direct aniline black dye, gum tragacanth solution and Water, to the flesh side, and then drying, then applying a pigment finish coat of carnauba Wax solution, beeswax solution, casein solution, oil of mirbane, prepared blood, black pigment and water to the flesh side of the skin, and drying, then applying a top finish coat of aqueous shellac solution, a Waterproof binder and water on the flesh side, then drying the skin and giving the flesh side a final glazing or polishing.
3. As a new article of manufacture, a tanned skin in a condition of having its flesh side finished by buffing, having applied a bottom dye coat, having applied a pigment finish coat, having applied a top finish coat and then a final glazing and polishing to produce a skin having a smooth finished appearance on its flesh side.
4. Method of tanning and finishing skins, which consists in tanning a skin in the ordinary manner, then bufling the flesh side ofithe skin, then applying to the flesh side of the skin, a coat of bottom dye formed of: fourteen (14) grams direct aniline black dye; eight (8) ounces gum tragacanth solution (2 oz. gum tragacanth per gal. water); one (1) quart of water; and then drying, and when dry applying to the flesh side of the skin a pigment finish coat formed of eleven (11) liquid ounces beeswax solution, (carnauba wax solution); sixteen (16) liquid ounces aqueous shellac solution; twentyseven (27) liquid ounces aqueous solution of casein, albumen and shellac; two (2) liquid ounces oil of mirbane; fifty-two (52) liquid ounces prepared blood; fourteen (14) liquid ounces lamp black; thirty-six (36) liquid ounces water; one and one-half (1 gallons water; and then drying the skin, and when dry applying to the fleshside of the skin a top finish coat formed of: eight (8) liquid ounces aqueous shellac solution; eight (8) liquid ounces aqueous solution of casein, albumen and shellac; sixteen (16) liquid ounces water and then drying, and when dry giving the flesh side-of the skin a final glazing or polishing.
In testimony whereof. ll aflix my signature.
