COMPOSITION BODY FOR SHOE-SOLES AND THE LIKE.

' Specification of Letters Patent.

- Patented July 5, 1921.

Application filed February 7, 1919. Serial No. 275,5es.

To all whom it may concern:

Be it known that I, HENRY K. EoKEL, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in a Composition Body for Shoe-Soles and the like; and I do hereby declare that the following is a full clear, and exact description thereof.

My invention relates to new and useful i improvements in compositions of material having wear resisting qualities and adapted for use for shoe soles, floor coverings, or for similar uses requiring a somewhat flexible,

body.

It is in general the ob ect of my invention to improve the wear resisting qual1t1es of compositions of this character, and it is more particularly. my object to provide a' wear resisting body which may be built up of a lurality of layers of woven fabric material connected by a suitable binder embodying wear resisting qualities.

A further and important object resldes in the provision of a composition of this character which may be manufactured at a minimum cost and which to this end may,

. without detractin from its efficiency, utilize fabric woven of s ort fibers not able to meet the tensile strengthrequirements of ordinary commercial fabrics and hence available at a low cost.

With the above and other objects and advantages in view, which will be apparent as the description proceeds,- my.inve-ntion resides in the novel features of construction, combination and' arrangement of arts as hereinafter more particularly descrl ed and defined by the appended claim.

In the accompanying drawings: a

Figure 1 is a-perspective view of .a section of a composition wear resisting body incorporating my invention..

Fig. -2 body.

Referring now more particularly to the accompanying drawings, my improved comthe fa is a sectional view through the cotton or other suitable material, This fabric is preferably made up of short fibers condncing to an exceedingly low cost of the fabrici) Inasmuch as the tensile strength of ric is not material to my composition. "lhese layers of fabric are embedded in and impregnated with a mixture 6 formed essentlally of adhesive substance into which is mixed powdered hard mineral substance to reslst wear. The mixture 6 is preferably composed of "rubber cementwith which is mixed powdered hard iron ore and silica and relatively small quantities of linseed oii and gasolene to form a vehicle reducing the conslstency of the mass. While I prefer the use of rubber cement, which makes a waterproof body, other adhesive material may be employed which is somewhat flexible in its effective form. Also other variations in the mixture may be resorted to without departlng from the spirit of my invention. The adhesive mixture is preferably reduced for application to the consistency of a thick amt. It is then coated upon the individual ayers of fabric and the layers are placed together and subjected to considerable pressure to form the complete com exceedingly economical, durab e and otherwise eflicient composition body 'is thus rovided which is flexible in nature and w ich is particularly adapted for use for shoe soles, floor coverings and the like.

. What is claimed is:

r A wear-resisting composition body comprising a plurality of layers of woven fabric impregnated with and maintained in cohesion by rubber cement mixed with powdered iron ore, the fabric material constituting the major portion of the composition.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Wiscousin. 1
