My invention relatesl to improvements skins or pelts of fur bearing animals, and more particularly to the method of reinforc- 5 fur bearing animals, normally too weak structurally to be satisfactorily employed in the manufacture of articles ef the furriers art, whereby such skins can be utilized advantageously in the manufacture of fur garmentsl and the like.

It is well recognized that a number of animals bred in captivity, and some wild animals as well, in particular the rabbit and the ordinary house cat, have fur which is admirably adapted for fur garments and the like. The fur of such animals, however, can not be successfully employed in the manufacture of fur garments because of the fact that their skins are too weakstructurally to withstand the different operations as stretching, sewing, and thel like, incident to fur garment manufacture, without being irreparably damaged or renv dered utterly useless. Because cf the weak- .ness of the skins of this class of fur bearing animals, the fur of such animals which is and would be otherwise-suitable for garment manufacture, is practically of little or no com'- mercial value for such'purpose.

Accordingly7 onevof the objects of my invention is the production of fur skins, normally too weak structurally to be employed in the furriers art, having a strengthened texture, and which are especially adapted for use in garment manufacture.

Another objectvof my invention is the meth- 0d of reinforcing or strengthening the texture of normally weak skins of fur bearing animals bya-pplying a composite backing to the inner or flesh side of the skins.

A further object of my invention is the method of reinforcing the texture of normally weak skins of fur bearing animals by applying a composite backing comprising a reticulated fibrous material embedded ,within an adhesive coating compositionto the inner or flesh side of the skins.

Other and further objects of my invention will appear from the more detailed description of my invention set 'forth below, it being i understood that various changes may be made therein by those skilled in the art without departing from the scope and spirit of my invention. ing or strengthening the texture of sklns of Basically, my invention relates to a method of reinforcing or strengthening the skins of fur bearing animals, which are normally too weak structurally to be adapted for fur garment manufacture, by applying a 'composite `backing comprising either a single or a plurality of layers consisting of a fibrous reticulated material embedded within an adhesive coating composition to the inner or iesh side of theskins as illustrated in the accompanying drawings, in which- Fig. l is a plan view with parts broken away, showing the flesh side of the skin having a composite backing consisting of an open m'eshed 'fabric embedded within an adhesive l composition. y

in adhesive coating compositionsl Fig. 4 is a plan view, with parts broken away, showing a modification wherein the composite backing includes a plurality of layers of reticulated fibrous material embedded within adhesive coating compositions. y In carrying out my invention I apply to the iesh or inner face of a structurally weak fur bearing pelt or skin ,4, a plastic adhesive coating body 5, Apreferably a pyroxylin composi- 86 tion having as its basic ingredient cellulose nitrate, and I 'then impregnateA an open' meshed fabric 6, as fiy netting or mosquito netting with the same or an equivalent adhesive coating body. I then place the coated 90 iesh side of the fur upon the impregnated fabric, the fabric being preferably passed forward as a belt, and suitably cut portions of the skins being laid upon the belt so as to completely cover it. The fur skin v carrying the composite backing is then dried whereupon the cohesive coating body having the open Ameshed fabric embedded therein unites the fabric with theflesh side of the skin and thus strengthens er reinforces 10 skins to a continuous web of open meslied fabric I obtain a fur surface of any desired Width and length, the Web of fabric serving ,the

double purpose of structurally reinforcing the individual pieces of skins and at the saine time holding together' the different pieces of fur as in one continuous piece. It is to be noted that the flesh side of the skins to Which my composite backing is to be applied shouldbe properly tanned. Furthermore, While I prefer a pyroxylin'coating composition having as its basic constituent a cellulose nitrate I may also use othercellulosic adhesive compositions as cellulose acetate, viscose, and the vlike as the medium in applying the composite backing to the fur skins.

Some skins of fur bearing animals, although carrying a reinforcing medium4 or composite backing on the inner or fiesh surface consisting ofa coating or layer having an open meslied fabric embedded 'Within an adhesive coating body, do not possess the j requisite strength, I have found that the required additional strength can be imparted to such skins by applying a second `fayer or coating consisting of a soft' open meslied fabric of a finer mesh than that4 of fly netting, as for example cheese-cloth, embedded Within an adhesive body, to the first layer of reinforcing medium/or backing. This is -preferably done by first soaking the cheesecloth in the adhesive composition, and then applying the soaked cheese-cloth to the fly netting coating by pressing the cheese-cloth against the fly netting coating until proper adhesion is secured. If a stillgreater reinforcement is desired Ipaint the backing mediumv with pyro'xylin lacquer, which due to the open mesh of both thecheese-cloth and the f'ly netting readily penetrates to the skin surface of the fur bearing pelt, thus producing a composite reinforcement after the solvent in the lacquer has been evaporated or dissipated.

lIna modified form of my invention, I coat the flesh side of a properly tanned skin4 with an adhesive coating body 5, as a pyroxylin adhesive composition orother like composition,.and While the coating is still in a wet cond1tion,`I dust fibers of cotton or other material 7 on the freshly treated flesh surface. The fibers are dusted over the Wet surface, either in an irregular manner so that the individual fibers have no distinct orientation,

4 or the fibers are dusted from a moving carrier in such manner that the greater portion of the fibers lie more or less in a single direction. After the reinforcing medium has been' dried, other coatings of the ,adhesive or coating material alone, or of thecoa'ting material and fibrous material may be applied, and Where a plurality of coats of fibers are applied, the coatings may be oriented differently" if desired, the fibers forming one coat being at .bedded ivithin an adhesive, and so on, every other coating or layer carrying an open ineshed fabric. In some cases the reinforcing medium or composite backing may consist .of only tivo layers, the one layer having the reticulated fibrous material embedded therein andthe other having the-open ineshed fabric embedded therein.

Having described my invention, I claim 1. The method of increasing the strength of fur skins which comprises applying a coating composition to the flesh side of such skins through the openings of an open-inesh fabric in contact lWith such. skins.

2. The-method of increasing the strength of fur skins which comprises'applying an open-mesh reinforcing fabric to the flesh side of such skins, coating the skin Withl a liquid coating composition through the open meshes of the reinforcing fabric. and thereafter causing the solidification of the coating composition.

3. A fur skin reinforced on its flesh side by a composite backing comprising acoating composition and an open-mesh fabric the individual threads of which are Wholly em-`
