Application June 16, 1937, Serial No. 148,481

8 Claims. (e1. 12-146) This inventionrelates to a boot or shoe, and more. particularly to a vamp lining therefor and to certain novel steps in the method of making the boot or shoe;

3 One object of the invention is to provide a novel and improved vamp lining of a construction such that the lining may be handled as a one-piece;

ll lining comprising. a sheet of twill or similar hard twisted fabric and a sheet of relatively soft ma- ,terial adhesively secured together to. comprise a one-piece vamp lining, and in which the adhesive is selected to be capable of permitting the 2o toe portion of said component parts of the vamp,

lining to be conveniently separated by the operator, as by the use of heat or solvents, to permit the operator to readily insert the box toe blank between the toe portions of component parts of 5 the lining.

A further object of the invention is to provide a novel and improved method of making a boot or shoe, and more particularly in certain novel steps .thereof comprising'the formation of a one-piece "3o vamp lining blank, the separation of the toe portion thereof and the introduction of the box toe blank between the separated toe portions of the component parts of the lining blank whereby the shoe may be manufactured at minimum expense as and in a simple and more emcient manner.

with these general objects in view, and such others as may hereinafter appear, the invention consists in thevamp lining and inthe steps in the method of makingthe boot or shoe hereinafter described and particularly defined inthe claims at the end of this specification. I In the drawing illustrating the preferred embodiment of the invention, Fig. l is a perspective .of the improved vamp lining with the toe portions 45 thereof separated in position to receive the box toe blank; Fig. 2 is a longitudinal section of the one-piece vamp lining blank prior to the separation of the toe portions thereof; and Fig. 3 illustrates a composite sheet from which a plurality so .of the novel vamp lining blanks may be cut.-

In its broader aspects, the invention contemplates a one-piece lining blank of a structure capable of enabling the toe portions thereof to be separated into two components for the reception s5 therebetween of a box toe blank.

In the manufacture of the boot or shoe, the toe portions of the improved lining blank are separated prior to the lasting operation, either in the stitching room, in the lasting room, 'or at any other suitable time, to enablethe box toe blank 5 to be conveniently inserted between the component toe portions and the lasting operation to be performed.

In the preferred embodiment of the invention. the improved vamp lining comprises a composite structure formed of an underlying foundation member of relatively hardfabric, preferably in the nature of a twill or similar hard twisted fabric and an overlying sheet of flannel or similar relatively soft material secured to the underlying foundation member to form a one-piece vamp lining. The individual vamp lining blanks may be cut or otherwise formed from a sheet of such composite material in accordance with the usual practice of producing one-piece vamp linings' The overlying flannel or similar sheet is preferably adhesively secured to the underlying foundationmember by the use of an adhesive selected to be capable of being rendered soft by heator the use of solventsin order to permit the toe portion of the flannel component to be detached from the toe portion of the underlying foundation member so that in the manufacture of a boot or shoe the .toe portion of the vamp lining blank may be readily separated, as by the operator in the stitching or lasting rooms, and in the manner described, and the usual box toe blank may be conveniently inserted between the separted toe portions of the component parts I of the one-piece lining, and thereafter the box toe blank and lining may be lasted in accordance with the usual practice.

Referring now to the drawing. It represents the composite'material fromwhich a plurality of individual one-piece linings i2 may he died out or 0 otherwise formed in accordance with the usual practice. Preferably the composite sheet in comprises an overlying layer or sheet of flannel if or similar relatively soft material and an underlying foundation member I6 preferably in the nature of a twill or similar hard twisted fabric. The sheets If, It are combined into a onepiece sheet by an interposed layer of adhesive l8 and the adhesive llis'selected to be capable of being softened by heat or by solvents or in any other suitable manner, for example.-by subjecting the blank to impact to destroy the adhesive bond between the components of the toe portion of the blank. -In addition, if found of advantage, the f toe portions of the blank may be separated by suitable mechanical methods, as by cutting or slicing the toe portion of the blank.

In the manufacture of a boot or shoe in accordance with the present invention, the one-piece vamp lining of the construction above described may be treated by the operator in the stitching 'room to render the toe portions of the component members l4, l6 of the one-piece vamp lining to be capable of being separated into a position such as is shown in Fig. 1. This may be conveniently accomplished in various ways as hereinafter described, such for example, as bysubjecting the toe portion to heat as by dipping the same in hot water, or exposure to steam, if the adhesive is one which is capable of being softened by heat, or by. dipping the toe portion of the vamp lining into a solvent, if the character of the adhesiverequires a solvent to soften the same, or as above set forth, by suitable mechanical operations. In-any event, the lining may be separated at the toe portion with minimum effort and at minimum expense and the usual box toe blank readily inserted betweenthe portions of be readily separated. If desired, other adhesives.

may be used including known forms of thermoplastic cements such as gums, adhesive gutta percha, latex, or rubber compositions. If found of advantage, solvents for the rubber or gums may be used in order to effect softening thereof to enable the toe portions of the vamp lining blank to be separated instead of heat, or such solvents may be used in conjunction with heat. When Celluloid and similar organic adhesivesare used, suitable organic solvents such as acetone may be required to effect the softening of the adhesive.

From the. description thus far, it will be observed that the present vamp lining blank posscsses important practical advantages over any lining blanks of the prior art of which I am aware, and among which may be mentioned the fact that the one-piece lining blank enables all of the advantages of a two-piece lining blank to be secured, while at the same time permitting the material to be handled as one fabric instead of two; to be cut in one operation instead of two; to be put up or cased as one type instead of two; and because of the fact that the combination of the component parts of the lining blank occur before introduction of the blank into the shoe the production of wrinkles is eliminated, enabling in some instances the necessity for cementing the flannel component to the leather vamp to be eliminated. In practice the toe portions of the lining blank are opened back-to a predetermined depth thereby enabling much better registrationof the box toe blank within the component portions of the lining blank to be secured.

While the preferred embodiment of the invention has been herein illustrated and'described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:
