LEATHER COHEPOSXTON .application led December 20, 1927.. Serial No. 241,424.

.'llhis invention relates to leathercompositions and more particularly to the art of manufacturing leather stock which will be strong and durable, pliable, not likely to crack t and capable of use in the various trades.

Une of the objects of my invention is to produce a leather stock composition of any i desired weight having many of the prop-erties of pure leather in that it will not crack w or split across the grain, presenting all the outside appearances of pure leather when tanned, and which is capable of being manufactured at comparatively low cost in any desired dimensions, colors or shades.

A further object of my invention is to produce a leather stock composition which will not deteriorate under unfavorable temperature conditions, possessing strong wearing qualities, capable of being cut and worked according to patterns in the different arts,

and possessing physical properties whereby tmay be employed in place of leather substitutes.

'llo enable others skilled in the art to more fully comprehend the underlying features of my invention, that the same may be embodied in the practical use and for'the purposes intended, reference is had to the accompany-- ing drawing forming a part of the specification in which lEig. lis a view showing the composition. lFig. 2 is a sectional view taken on the line 2 2 of Fig. l.,

Referring now to the drawings wherein like reference numerals designate corresponding materials entering into the manufacture of the composition as illustrated, the product and its physical properties may be best understood by one of the many methodsor processes employed in its manufacture. ll first employ a finel woven top and bottom cotton sheeting, drill, gauze or

canvas

6, 7 of any desirable length or width forretaining a liller 8 which constitutes the body of the stock. rlhe filler may be of any desired thickness and consists preferably of linoleum, ground cork, finely divided leather waste or its equivalent. A binder for the filler is preferably a non-drying oil such as 5 linseed oil, glycerine or other non-oxidizing finished appearance to the back of the composition. To the top sheeting 6, a layer of thin leather l() is cemented thereto, sufficient uniform pressure being applied so'that it binds not only with the sheeting but also with v the filler. When thus completed, the edge of the composition may be colored, waxed, polished and burnished if so desired, ready for use in the various arts. l

llt should be pointed out that the completed product or com osition is not to be regarded as a leather su stitute. lin fact its appearan ce and feel, even to the inexperienced clearly indicates that it is not a leather substitute. ln a certain sense, the composition consists of a body or backing for light weight or thin sheet leather which of itself cannot be employed in many arts. rlhe body or baclnng which consists of the filler andthe top and bottom fabric is capable of being produced in any desired thickness depending upon the amount of hller and pressure ap hed ,during the process of manufacture.l onsequently various grades or weights of the stock may be produced for the purposes desired. The stock will not tear or rip and will stand considerable wear before the layers may be penetrated.` The cost of manufacture being considerably cheaper than pure leather and since it possesses in addition to the above physical characteristics, the'appearance o quality, the composition has been found to be a coer- Vcial necessity in thereduction of manufacturing costs of various articles of merchandise in which it is employed.

While l have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reservethe right and privilege of changin the form of the details of construction or ot erwise altering the arrangement of the correlated parts without departing from the spirit of the in.

vention or the scope of the subject matter being claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A leather composition consisting of a top and bottom fabric having a semi-plastic filler therebetween, granular material applied to the face of the bottom fabric and a layer of thin leather cemented tothe top fabric.

2. A leather comrosition consisting of a top and bottom fa ric having a linoleum filler therebetween, granular material applied to the *face of the bottom fabric and a layer of thin leather cemented to the top fabric.

3. A leather composition conslsting of a top and bottom fabric having a non-drying ller 'therebetween impregnating said fabric, granular material applied to the face of the bottom fabric and a layer of thin leather cemented to the top fabric.

leather composition consisting of a top and bottom, finely woven fabric, a nondrying linoleum filler therebetween impregnating said fabric, a layer of granular cork applied to the tace of the bottom fabric and a layer of thin leather cemented to the top fabric.

5. A. leather composition consisting of a top and bottom, nely woven fabric which may be drilling, gauze, cotton sheeting or their equivalent, a linoleum liller havin a nondrying binder which may be linsee oil impregnated in said woven fabric, a layer of granular cork applied to the face of the bottors fabric and a la er o thin leather cemented to the top ta ric..

lin testimony whereof l'ax my signature.
