IMPROVEMENT N THE TREATMENT OF LEATHER.
Specification forming part-of Letters Patent No. 165,] 29, dated June 29, 1875; application filed December 16, 1874.
To all whom it may concern:
Be it known that I, HUGH SMITH, of the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements'in Leather; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the art to which it pertains to make and use the same.
This invention consists in producing from split or buifed leather a perfect imitation of grain leather or morocco, made from any kind of skins or hides, by the use of certain compounds, which are hereinafter more fully described; and first consists of glue, one-quarter to one pound, dissolved in one gallon of water, and boiled, after which is added thereto one-quarter to one pound of starchor flour, and the 'whole mixture is again allowed to boil, after which aniline colors or paints of any kind may be added; also, use fromone' to four pounds of glycerine or other fatty substance, and mix therewith any desired colors of paints to correspond with the colors of the dyes. The-whole is mixed together. Of this compound, one orniorc coats may be used previous to stamping or embossing the leather under treatment, the object of which is to fill up the pores, and binddown the fiber or nap on the surface thereof; and. if it is not required to be water-proof, it may be finishedwith one or more coats of a suitable varnish.
And my second compound, which I use to make the leather more flexible and waterproof, consists in a sirupy solution of the following ingredients, and in about the followin g proportions, viz: One pound of gum-shellac dissolved in two quarts of alcohol, and
added thereto or used separately; one pound of india-rubber or other equivalent gum, also dissolved in one gallon of naphtha, (the latter pound applied, which is done with a sponge, brush, swab, or any other suitable device, and well rubbed in upon the surface of the split or'butfed side of the leather, one or more coats, either warm or cold, being applied, until a uniform color and smooth surface are produced,
which, after being properly dried, is stamped or embossed, to imitate the natural grain of the leather or morocco or other design, as the case may be, the first preparatory coating to be applied previous to the stamping or embossing process.
I claim As animprovement in the art of treating leather, the compounds composed of the ingredients named, in about the proportion given, for the purpose specified.
In testimony that I claim the foregoing as my own invention I affix hereto my signature in presence of two witnesses.
HUGH SMITH.
