Letters Patent No. 76,897, dated April 21, 1868.

IMPROVED GOMPOSITION FOR BLAGKING LEATHER.

TO ALL WHOM IT MAY CONCERN: e 7

Be it known that I, JOHNN ENGELHARDT, of the city ofCarbondale, in the county oi'Luaernc, and State of Pennsylvania, have invented a new and improved Leather-Blocking Composition; and I do herebydeclare the following to be a clear, exact, and full description thereof. I i

The nature of my invention consists in combining lager beer, oxide of iron, and logwood in such a manner as to produce, when applied to leather, a jet-black color, that may be readily polished without the addition of v I varnish.

The object of my invention is, first, to avoid the nastysolution composed in part of urine and 'copperas; second, to give a better black; third, to give a more permanent coloring; fourth, to provide a surface that will polish without the addition of varnish or other expensive coating;'fifth, to economize in cost,

This, composition has'many advantages-over the ordinary compound used for the purpose of coloring leather. The matter generally used, more especially in harness, shoemaker, and other shops, is composed, in part or wholly, of urine and copperas, which is an almost intolerable nuisance, because it is esscntial,to heat the solution every time it is used, commonly done by plunging a red-hot pokcrintothc not, producing a most disgust- I ing odor. It also colors the hands and clothes of the workmen, and the bench and whatever else it comes in contactjvith- This hearicompnund has no offensive odor, and does not color the hands, clothes, or hone-hos ol' the workmen. I I

The copperas-urine solution yields a dull, reddish-black color, which must be treated with tallow or varnish to bring out'the color desired, and lustre. This beer-eompound at'onceyields a coal or jet-black color,

that, by rubbing with a dry rag or a slicker, gives a fine polish, improving very much the appearance of the leather or work. 1 p s v The cepperas-colored leather soon fades to a reddish white when exposed to air and water. Leather colored with this beer-composition seems to retain its color through long exposure to air and water.

Harness-makers usually finish up their work with tallow or varnish. Work covered with this beer-compound does not need tallow or varnish, asthe surface and edges finished and rubbed with this compound have more lustre, and of a superior character, than can be made with tallow, and with considerable less expense.

The urine-copperas solution fnils'almost entirely on split leather, whilethe beer-compound works equally well on split as on the grain. 1

To enable others skilled in the arts to make and use my invention, I will proceed to describe the compound, and my manner of making the same. Y 1 4 I add, to one gallon of lager beer, one ounce of the oxide of iron, and one ounce of logwood. The -mixturc should be stirred together, and allowed to stand for a few hours, when it is ready for use in the same manner as the ordinary preparation used for the purpose of blacking leather.

In practice, I procure the sour lager beer and becr slops from the lager-beer saloons, the only cost being that of carrying it away. This I place in an iron vessel, andto it I add at the rate of two pounds of logwood tor. barrel of beer, and a peck, more or less, of iron-tnrn'ings or filings, or some old horse-shoes or nails, or any old cast or wrought iron that comes handy. The quantity of iron need not be definite; only be sure to get enough. If the vessel be filled up every night with the beer-slaps, it may be nearly used out during the following day, and so repeated indefinitely by occasionally adding more iron and logwood.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, isi The ingredients in combination, substantially as described'for the purpose named.
