IiINOLEUM PRODUCT AND PROCESS OF MAKING THE SAME.
Specification of Letters Patent.
To all whom it may concern;
Be it known that I, JOSEPH W. Wnzuaa citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State ofPennsylvania, have ina process for making such product.
My primary object is to provide. an improved boot and shoe inner sole that will be impervious to moisture, sanitary, lIlBX-' pensive and durable, preferably an insole having a body of 'sheeted linoleum composition'with its faces coatedby water-proof composition which is in turn covered by a woven fabric such asmuslin.
' The improved product is produced in highly desirable form and character by my process which consists in feeding linoleum composition between sheets of woven or felted fabric coated with a water proof composition such as oil paintplaced in contact with thelinoleum composition and subjecting the coated sheets with the linoleum composition between them to the action of heated calendering rolls or a press, whereby the several elements are united in properly consolidated sheets and the desired character of union obtained by the softening of the compositions by the heat applied, with a resulting desirablefirm union, particularly between the softened coating of the fabrics and the body of linoleum composition.
In the accompanying drawings, Figure 1 is a perspective view of an inner sole designed to illustrate my improved product; Fig. is a sectional view of a composite sheet made in accordance with my invention but having the woven facings partially detached' for the purpose of indicating the J composite character of the product; Fig. 3
is a sectional elevation of apparatus adapted product; and Fig. 4 is a part sectional elevation of a second form of apparatus adapted to be used in the process of making said pro ct.

Application filed January 24, 1917. Serial No. 144,147.
-The product, as illustrated in the drawings, comprises the linoleum composition body I faced by the adhering coatings of water-proof paint 2 which are covered by the adhering woven fabric 3.
This composite product is. formed, as illustrated in Fig. 3, by passing between heated calendering rolls 4 the sheets of coated fabrics, from the rolls 5, and the linoleum composition .6, which is rolled between the sheets of coated fabric and makes a permanent union with the water-proof coatings through the softening of them by the heat.
The product may also be formed by means of a press (as shown in Fig. 4) having the heated stationary head 7 and the heated plunger, 8 between which are drawn the sheets of coated fabric from the rolls 9-and 10, with the linoleum composition 6 between them, the product of the pressing operation comprising the sheeted linoleum composition body 1, the coatings of waterproof paint 2 adhering to the faces thereof and the sheets or muslin or other fabric 3 adhering to'the coatings.
Having described my invention, I claim:
1. The insole comprising a sheeted linoleum composition body, coatings of waterproof paint adhering to the faces thereof, and coverings of woven fabric adhering to said coatings.
2. The process which consists in passing sheets of fabric having water-proof coatings and linoleum composition between heated calendering rolls with the coatings of said fabrics in contact with the composition fed between the sheets, and heating and pressing the sheets and composition so as to sheet the latter, soften the coatings and cause the contact with the composition, subjecting the coating to sufficient temperature to soften it, and pressing the fabric and composition so as to cause the coating to adhere to the composition.
In testimony whereof I have hereunto set my name this 19th day of January, 1917.
