Description

UNITED STATES PATENT FFICE.
JULES LOUIS MORET, OF PARIS, FRANCE.
COMPOSITION FOR DEPILATING HlDES.
srnorrronrron forming part of Letters Patent No. 281,287, dated July 17, 1883. Application filed January 19, 1883. (No specimens.) Patented in England May 10, 1882, No. 52,213.
To aZZ whom it may concern.-
Be it known that 1, Jonas LOUIS Months, of
Paris, France, have invented a new Composition for Preserving and Unhairing Hides and Skins; and I do hereby declarethat thefollowing is a full, clear, and exact description of the same, and that I have received Letters Patent of England for fourteen years for said invention, which bear date May 10, 1882, No. 2,213.
This invention relates to a composition for enabling hides and skins to be preserved for transport or storage in such condition that while the hair remains firm until it is desired to remove it the hides and skins may be immediately unh aired at any subsequent time by a simple steeping in water-that is to sa they are impregnated with the depilat my agent and with a suitable preservative, so that while pro-.
tected by the latter from dry-cracking or putrefaction and from the attacks of insects, the former, being already contained in the pores of the skin or hide, is brought into such intimate contact with the hair follicles or glandsas to act with immediate effect thereon as soon as the hide or skin is plunged into water, loosening the hair and enabling it to be removed with case.
To prepare the composition for this purpose I first make a strong solution of American pot ash, or ordinary caustic potash, and heat to from about 180 to 200 Fahrenheit. Ithen add (stirring the composition well meanwhile) realgar in powder in the proportion of about two ounces to three and a half ounces for each pound of potash employed. I may also add quicklime in the proportion of three ounces, five ounces, or seven ounces for each pound of potash, the precise proportions in each case depending on the kind of potash used and on the manner in which the composition is to be applied or used. The quicklime may, however, be dispensed with altogether when the potash is sufliciently caustic without it, the
quicklime being only used when and in such quantities as it may be absolutely required to efi'ect this object. The composition is allowed to settle and the clea liquor decanted ofi'. This clear liquor is diluted with water to be applied, either with a brush or mop, to
the hide or skin, or by immersion, the hides or skins being either left in this state or dried, according as they are to be kept a greater or less length of time. In the dry state they may be kept for an indefinite period, and may be at any subsequent time restored to their original green and natural condition by simply steeping them for about twelve hours in water, whereupon the hair and send may be immediately removed with case without further treatment with chemical agents.
This mode of preservation forms an admirable substitute for the salting treatment generally used for preserving hides, and renders unnecessary the injurious liming or other treatment for unhairing. The quality of the leather obtained from hides thus preserved by my improved process will be found to be superior to that of hides treated in the ordinary way.
I do not here claim depilating hides by sulphide of arsenic, either alone or dissolved in a solution of potash.
I claim- The herein-described composition for impregnating hides and skins and preserving them in such condition as to be capable of being unhaired at any subsequent time by asimple immersion in water, such composition be ing composed ofa solution of caustic potash JULES LOUIS MQRET.
