1910.- Serial No. 555,189.
To all whom it may concern: I
' Be it known that I, lt'lixnoitnn'r M. GREGG, a citizen of the United States, residing at Brooklyn, in the county of Queens, State. of New York, have invented certain new and-useful Improvements in Processes of Coloring Leather and Products 'lhereof, of which the following is a description.
My invention relates to a process ofcoloring the surface of leather and to the article produced by the process,
My invention has for its object to produce 'byimu-iersing leather in a bath of dye a widely and irregularly variegated colored surface, andmy invention consists in the process andv article hereinafter described In carrying out my invention I take a soften it by wetting it thoroughly in water, preferably cold water. 1 then place here number of. small articles such as spools, marbles, pebbles, buttons or the like, and gather the leather about each one, or it may be two or more together, and tie it with cord or twine sutliciently to retain the article within the skin. I also gather the portions' of the skin not occupied by the articles described into bunches of preferably irregular shape; The skin thus tied and whilestill wet is then imn'iersed in a bath of dye of the color desired and allowed to remain a few minutes only. It is then the skin thoroughly washed and stretched while wet so as to leave it smooth and comparatively flat, and dried. \Vhen thoroughly dried the skin may be finished with a coat of spirit varnish or in any other convenient way, or if desired may be left with- The dye used may be any dye suitable for coloring leather suchas the acid or basic dyes commonly used.
If desired to produce leather having two or more shades, the tied skinafter being immersed in a bath of one color should be dye and either with or without rinsing, is then, while still wet, immersed in a bath of the other color desired and thenrtaken out,
The tying of the skin may be more or less r pending upon the extent to 'which tightvde it is desired to have the color of the skin as tanned appear oncthe surface after dyeing.
The surface of the skin treated as 'above described presents a widely and irregularly variegated eflect due to the fact that by the tying of theskin iii-bunches it is in parts more or less protected froiu'the action of the dye, as well as to the fact that inparts the skin is or may be stretched more or less tightly about the articles placed on its flesh side while in other parts ltllS not stretched. lftied tightly more or less oftthe color of the undycd tanned skin will appear on the finished. product shading off into the color of the dye. v 1
The most desirable results are obtained where the articles tied in' and thetbunches formed as above described are arranged with little or no attempt at regularity.-
It a ring thus described my invention, what I claim is:
1. The herein described process of eolor ing skins which consists in wetting the skin,
gathering it in irregular bunches,tyingthe bunches, immersing the skin so tied 'while still wet in a bath of dye, removing the skin fromjthe bath and smoothing out while still wet, and drying.
- 2. The herein described process of-eoloring skins which consists in wettih theskin, placing an article on the flesh-s1de tif-lthe skin, gathering the skin in a bunch abofit the article, tying the bunch so formed, immersing the skin so tied while still wet in a. bath of dye, removing the skin from the bath,
untying while still wet, smoothing out and drying. v
3. The herein described process of color.- ing skins which consists in wetting the skin, gathering it in irregular bunches, tying the bunches, immersingfthe skin so tied, while still wet, inaba'th of dye, removing the skin from the bath, immersing it while still tied and wet in a second bath of dye, uutying and smoothing out while still-wet and drymg.
4. Leather having the variegated colored surface herein described prodycea by wet-
