'3 Claims.

Thi invention relates to shoes, slipperaand similar forms of footwear of the lighter weight varieties, all of which, for convenience, will be hereinafter referred'to collectively as shoes."

The invention aims to improve both the construction of the platform types of shoes and also their method of manufacture with a viewtoreclucin the expense of the manufacturing operations, while at the same timeproducing a serviceable article. A particularly important object of the invention is to eliminate the lasting operation.

The nature of the invention will be readily .understocd from the following description when read in connection with the accompanying drawings, and the novelfeatures will be particularly pointed out in the appended claims.

In the drawings, f

Fig. 1 is a perspective view of a shoe illustrating one form which the invention may take;

Figs. 2, 3, and 4 are plan views of the insole, platform, and vamp, respectively, of the. shoe shown in Fig. 1;

Fig. 5 is a perspective view illustrating the parts at one stage in the process of manufacture of the shoe;

Fig. 6 is a bottom view of the shoe after the assembly of the vamp, insole, platform and heel strap has been completed, but prior to the application of the outso-le; and

Fig. 7 is a transverse, vertical, sectional view taken through the forepart of the shoe shown in Fig. 1.

Referring first to Figs. 2, 3 and 4, an insole is illustrated at 2 in Fig. 2, comprising a shank and heel end section a whichmay or may not be separate from the forepart section b but is usually of a firmer construction than the latter. As here shown the forepart section has been slashed or scored transversely to increase its flexibility and an edge binding 0 covers the entire edge portion of the insole.

The platform 3 comprises a body member, usually thicker than the insole and of a more resilient or spongy character, and it is customarily reinforced with fabric on both its upper and lower surfaces. Its edge portion also is enclosed in a binding d.

' The vamp 4 may take a great variety of forms, the particular construction here illustrated comprising two sections of leather, or other'suitable upper material, crossed one upon the other, and stitched together and to a lining which completely covers the inner surface of the vamp and frequently, but not always, is made in a single piece. The manufacturing operations on the parts 2, 3 andd are performed entirelyindependently of eachother, and these parts are completed prior to the assembling operation.

I have found that the lasting operation can be successfully avoided by securing these parts- 2, Sand 4 together while they are in the fiat, with theshoe bottom members 2 and. 3 disconnected, except as they may be joined together by the vamp, and then bringing the latter members together in theircooperative relationship, and securing them-there. 1

In Fig. 5 a right shoe is shownand it will be observed that the right-hand edge of the vamp A has been stitched to the lower marginal surface of the insole 2 by the seam 5. Also the forward end of this edge of the Vamp is fastened to the toe portion of the insole by the stitching 5. and additionally by a staple '6. In performing these stitching and fastening operations the workman is guided by marks made for this purpose on the bottom of'the insole. The opposite or left-hand edge of the vamp is similarly secured to the upper surface of. the platform 3 by a scam I and additi'onally by a staple 8 atthe toe, the location of these parts being similarly determined by guide marks preliminarily and accurately placed on the platform.

The fastening of the upper to the two bottom members in the manner just described is performed while the parts are in the fiat, so that these operations can be performed easily and rapidly. Usually, also, in connection with these same operations the assembly consisting of the heel strap Ill and the ankle strap l2, which have previously been stitched together, is secured to the bottom of the insole by staples or equivalent fastenings I3, Fig. 6.

Next the bottom members 2 and 3 are superposed, one on the other, with their edges properly registered and preferably with the platform located under the forepart section of the insole. These parts are secured together intheir registered relationship by suitable fasteners, such as the staples indicated in Fig. 6 at I.

From this point on, the nature of the operations will depend largely upon the character of the shoe to be made and the manner in which it is desired to secure the outsole in place. Customarily this is done either by McKay stitching or by the cementing process. In either event, if a shank stiffener is to be used, it is secured to the insole at this time, and then the outsole l5, Fig. l, is laid and the shoe is McKay stitched, if that is the method of securing it to be employed. If, on the other hand, the outsole is to be cemented,

then a. last is inserted in the assembled upper, the upper surface of the outsole and the bottom of the entire assembly, as illustrated in Fig. 6, are coated with cement, and the shoe is placed in a press serving to hold the parts firmly together while the cement hardens and dries.

At some suitable point in this process, also, a lining 9', Fig. 1, covering the entire upper surface of the insole 2, is cemented to it. A heel I 6, Fig. 1, also is nailed or otherwise securedto; theheel seat end of the outsole at any, suitable point in the process.

It will be evident from the foregoing that; this invention completely eliminates the lasting operation, thus avoiding an expensive 'stepin the cus tomary process of manufacturing shoes and reinsole, platform and vamp, securing one lateral edge of said vamp to said insole and the other lateral edge to said platform while all the parts are in the flat, and with said first mentioned lateral edge of the vamp extending under the edge of said insole and said second mentioned lateral edge overlapped upon and secured to the opposite edge of the platform, placing one of said bottom members upon and in registering relationship to the other sothat the opposite lateral edge portiozisiof said Y mp will lie between said bottom members, subsequently securing them together in said relationship and securing an outsole to the assembly so formed.

" 2. That improvement in methods of making shoes, which consists in providing a shoe upper,

placing it with steps which can be performed much more rapidly, economically, and with relatively unskilled help. At the same time the in-H vention produces a shoe comparing favorably in serviceability with those of, corresponding quality customarily made byconsiderably more expensive processes. the opposite margins of the vamp 4 are initially securedto the insole and platform, respectively, while the parts are inthe flat, by some formpf mechanical fastening devices, such as stitches or staples, but that the insole, platformand outsole are secured together by additionalzneans operating entirely independently of those by, which the opposite margins of the vampare initially fastened to the: insole and platform, respectively. Also, that the securing meanswhich-holdsthese main portions of the shoebottom togethenmay be of a non-mechanical nature, such as a cement.

While Ihave hereincshown and described a preferred embodiment of my invention, itjwill be evident that the'invention is susceptible, of;.embodiment in other forms without departing from the spirit or scope thereof. 7 2- 'Having thus described -my invention, what -I desire 'to'claim .as'newis: I -:1.,

-;.-1. That improvement. in methods ,ofmaking shoes, which consists inhproviding a completed It will be observed [that in this shoe an insole, a platform, and an outsole, said upper including a vamp and said insole and platform having bound edges, while said vamp is in a substantiallyfiat condition securing one edge of said vampto the lower marginal surface of said insole andsecuring the opposite edgeof the vamp to the opposite upper marginal surface of said platform, superposingsaid insole upon said platform invregistered "relationship thereto and securing them together, thereby bringing the vamp into its;fi.nal relation to the shoe bottom, thereafter securing anoutsole to thebottom of the platform and fastening a heel to the heel seat portions of said insole and outsole. I

3; An open-toe shoe comprising a vamp, an insole, a platform'under the forepart of the insole,

means fastening one lateral edge portion of said vamp to the bottom of the insole only, other means securing the opposite lateral edge portion of said vamptothe top of the platform only, the vamp extending around the Opposite edges of the'insoleiandtboth edges of said vamp lying between the insole and the platform, additional means securing said insole and said platform togethenan outsole,/and means securing said outsole to said platform.
