TANNING AND DRESSING OLD LEATHER AND ARTICLES 0F SAME.
. SPECIFICATION forming'part of Letters Patent No. 302,132, dated July 15,1884.
' Application filed March 11, 1884. (No specimens.) i v T0 aZZ whom it may concern.-
Be it' known that I, EDWIN W. Hnwlrnia citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful composition and process for tanning old leather and old articles manufactured of leather, and
of properly dressing said leather or articlesafter such tanning; and I do hereby declare that the following is a full, clear, and exact description of such invention, which will enable others skilled in the art to which it pertains to make and use the same. The object of my invention is to thorough] cleanse old leather of destructive accumulations, and at the same time to tan itin such a manner that the leather will be restored to its pristine strength, softness, flexibility, and durability, and thereafter to so dress it that the appearance of new leather shall be given.
To carry my invention into effect the following ingredients are to be used, in the proportions named below, and mixed and used as hereinafter directed: sumac, (Rims glabmm, upland smooth Pennsylvania sumac,) dried and ground, ten pounds; the rootbf the American Water-pepper, (Polygonum bistortcn) dried and ground, one pound; the flowering stalks and leaves of dogfennel, (Achillea mt'llefolz'mn,) dried and ground, one-half a pound; commercial concentrated lye, eight ounces; commercial carbonate of soda, sixteen ounces; soft water, forty gallons.
To make a proper composition of these in gredients for the purpose contemplatedin this specification, the following rules should be observed: First, mix thoroughly the sumac, water-pepper root, and dog-fennel, and
pour upon them a gallon of boiling water; let stand a few minutes, when pour into eleven gallons of boiling water; let the whole simmer (not boil) over a slow fire for fifteen minutes; second, while the foregoing is simmering, dissolve the concentrated lye and carbonate of soda in one gallon of boiling water; third, into a barrel or other water-tight .-vessel of rather more than forty-gallon capacity pour twenty-seven gallons of cold soft water; 7
fourth, into the above pour first the alkalinesolution, then the decoction of sumac, waterpepper, and dog-fennel. The admixture is then ready for use. Put into the composiby an examination of the articles to' see if they are soft and flexible. After removing from the'composition, the articles should be thoroughly washed in clear, cold soft water, and then-hungupto dry. When half dry, they should be well oiled with neatsfoot oil.
Leather which has" had a blackened surface should be reblacked, before oiling, with a composition made of one part of copperas (sul phate of iron) dissolved in twelve parts of the tan liquor hereinbefore described, applied with'a brush or sponge, and when the blacking has well dried in, a black oil (composed of one part of fine ivory-black to twenty parts of neats-fo'ot oil) should be applied. The article should then be carefully wiped (preferably with a Woolen cloth) and a solution of gumtragacanth (in the proportion of one .ounce of gum-tragacanth to one pint of water) applied with a sponge. After wiping again, the artf cles will be ready for use. The gum-tragacanth ,solution should also be applied to those leathern articles which have not had a blackened surface. I
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The process of cleaning, tanning, and dressing old leather,which consists in first immersing the leatherin a solution consisting of sumac, ten pounds; root of American Water pepper, one pound; the flowering stalks and leaves of dog-fennel, one-half pound commercial concentrated lye, one-half pound; carbonate of soda, one pound, and water, forty gallons, mixed as described, until the leather oughly in clear, cold soft water; third, in
hanging up to dry; fourth, in oiling with neats-foot oil when half dry; fifth, in wiping the leather; sixth, in applying gum-tragacanth, and, seventh, in again wiping the leather.
I EDWIN W. HEWITT. Witnesses: I THoMAs MEYNELL,
JOHN MORRIN.
