The present invention relates to shoes of an improved construction and to an improved method of making shoes.

The primary object of the present invention is to simplify the art of shoe making and to reduce the cost of labor and material. More particularly, pursuant to this object of the invention the shoe is made in such a way as to enable the upper and the insole to be assembled in an improved manner without requiring a lasting operation and to facilitate the securement of the upper and insole to each other. A last or form may be, and preferably is, inserted in the shoe after the upper and insole are secured to each other, whereby to facilitate the attachment of the outsole and the usual shoe finishing operasuch a way that it can be manipulated so as to present successive marginal edge portions along a substantially straight line to the marginal edge of the upper during the operation of stitching the insole and upper to each other.

In accordance with the present invention, both of the insole and the upper are each cut to the size and shape they are to have, respectively in the finished shoe; and the insole is additionally cut in certain portions thereof, as will subsequently be described in detail; and thereafter the insole and the upper are stitched together.

Another object of the present invention is the provision of a shoe of improved construction, in which the upper and insole are secured together without the formation of wrinkles and bulges and without a lasting operation.

The invention may be embodied and practiced in various ways including but not limited to those hereinafter referred to by way of illustration but without limitation, and the above and other objects, features and advantages of the invention will be fully understood from the following description considered in connection with the accompanying illustrative drawings.

In the drawings:

Fig. 3 is a perspective view of the upper side of the insole, a portion being shown displaced to show a structural feature;

Fig. 4 is a sectional view taken on the line 44 of Fig. 2;

' Fig. 5 is a perspective view of the insole of Fig. 2 shown in an opened annular position; to facilitate the operation of stitching the insole and upper to each other;

Fig. 6 is a perspective view of the upper joined to the insole;

Fig. 7 is a sectional view taken on the line of Fig. 6;

Fig. 8 is a view similar to Fig. '7 showing a welt secured to the upper and insole; and

Fig. 9 is a view similar to Fig. '7 showing the upper of the shoe secured to the insole at the top of the latter.

Referring to the drawings and more partic ularly to Figs. 1 through 4 thereof, the shoe I0 formed according to the present invention comprises an upper l2, an insole 14, an outsole l6 and a heel [8. According to the method of the present invention the upper l2 and insole 14 are cut to the size and shape they are to have in the finished shoe and are secured to each other off the last; i. e., they are attached to'each other without the usual lasting operation. Pursuant to the present invention, the insole is prepared in the manner which will now be described.

Insole I4 is provided with a bevelled cut [8 which extends for substantially the full length of the insole l4 medially thereof in one part of the thickness of the insole but which terminates short of the ends 20 and 22 of said insole in the other part of the thickness of the insole, so that said insole is divided longitudinally but remains connected at its end portions. (See Figs. 3 and 5.) The longitudinal cut l8 comprises complementary bevelled edge portions 24 and 26 which are adapted to be secured together in lap joint fashion after the upper 12 and insole i l have been secured to each other as will be de scribed in detail hereinafter. The insole i4 is transversely cut at the toe and heel portions 21 and 29, respectively, at 28 and 30, respectively, with a bevelled out which extends from both extremitie of the longitudinal cut 18 and at both sides of said longitudinal cut. More specifically, the toe and heel portions of the insole are cut in planes lying between the planes of' the top and bottom surfaces of the insolasaid planar cuts being atan angle to said surfaces of the insole. Preferably the transverse cuts 22 and 30 at the ends 20 and 22, respectively, of the insole l4 are arcuate, conforming to the arcuate end edges H and I3, respectively, ofthe adjacent ends of the insole. It will thus be seen,

therefore, that the transverse cuts 28 and 30 are substantially parallel to their associated end edges II and 13, respectively, of the insole M at the ends and 22, respectively. The transverse arcuate cuts 28 and 3B divide the toe and heel portions 21 and 29, respectively, in between opposite surfaces 3| and'33 thereof, and one of said divided parts of each of said toe and heel portions, namely the bevelled outer marginal ally slit at 35 to form a plurality of, spaced radially M extending portions as (see Fig". 5), said slits'eiitending transversely of the outer marginal edge portions 32 and 34 for substantially the full widthi and pasting. or cementing.

thereof but terminate short of outermarginal 4 edge portions 31 and 39. ginal edge portions 32 and 34 are radially slit at 35,-which slits extend. radially. from the inner edges 38 and lb of the outer marginaledge por tions32 and 34, respectively. Thus the to'eand heel. portions Zlan'd 29, respectively, are divided in. a, plane of. division lying generally between the opposite surfaces of the insolev so thatthe toe portion 2'l has superposed portions 32 and. 33 and the heel portion 29 has superposed portions '34 and 31 The superposed portions 32, 33, and 34', 3'! areseparabl'e from each other 'at the plane'of division, and the superposed portions at outer m'arginaledgeportions 32 andlBd are, radially slit in the. manner aforedescribed whereas the superposedportions 33 and 37 each have two separate parts, namely the parts, G I, as, and sh ll; respectively. It will be noted that theparts ii t5, and the parts 43, 5 are on'opposite sides of the longitudinalcut it. As shownin Figs; 2 and 3,.the separablepairs of parts 4! and 43 at one end of the insole, and parts at and 41 at the opposite end, 'haveuedge portions extending from one end or the insole toward the op-posite end and out- Thus the outer mar manipulated as shown in Fig. 5,jit isadaptedi to bersecured to the upper l2; the. lower marginal edge portions 42 of'the upper 121 being adapted to be seeuredto the outer marginal edgeportions 44; of the insole M.

Thus the marginal edges "52 of the upper and the marginal'edges i ifof'the insole are fed fiatwise .in' successive increments and in superposed relationship to the work' support of a conventional sewing" machine or other securing means with said .edges-beingsubstantially parallel. In the preferred embodiments; as illustrated in Figs. 6-9 of the drawing the marginal edges of the insole are stitched to'the'mar- .ginal'edges of the upperbya line of stitching?! but it willbe readily apparent that any othensuit- V as snowman 8 the After the marginal edges 42 of the upper are stitched to the marginal edges 45 of the insole, the insole H3 is restored to its original form, that is the form prior to the aforedescribed cutting and slitting operations. In the preferred embodirnent the insole H5 is restoredto its original form by means of cementing the complementary cut edge portions to each other but it will be understood that said restoration may be effected by other means, for example, stitching, or stitching Thus the complementary bevelled edge portions 24 and 28 of the longitudinal cut i8 are pasted to each other to form alap joint and the outer marginal edge ortions or outer divided portions 32 and 34 are pasted to their associated inner divided or bevelled edge portions and 48, respectively, in lap jeint'fashion to form the upper and insole assembly fiflishown in Figs. 6 and '7.

While I have shown and described the preferred embodiment of my invention, it will be understood that various changes may be made in the present invention without departing from the underlying idea or principles of the invention within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
