3 Claims. (Cl. 12-142) The present invention relates to making shoes particularly ladies shoes of the typecustomarily referred to as walking shoes. This application is a division of our copending application, Serial No. 538,666, filed October 5, .1955, now Patent 2,841,891.

It is an object of the present invention to make a shoe 'which is flexible and lightweight and-is yet of sturdy, long drawings which illustrate a preferred embodiment; In

the drawings:

Fig. l-is a perspective view of an upper of a shoe made vaccording to the invention.

Fig. 2 is a fragmentary section taken approximately on the line 2-2 in Fig. 1.

Fig. 3 is a perspective view of a preassembled insoleoutsole unit.

Fig. 4- is a perspective view illustrating one step of at- :taching the upper to the sole unit.

Fig. 5 is a perspective view illustrating a further step,

the partially completed shoe being shown on a last and iinverted.

Fig. 6 is aside view of a compietedshoe. 7 :Figs. 7 and 8 are cross sections takenrespectively on lines 7-7 and 88 inFig. 6.

As-illustrated in Fig. 3, an insole 1 and outsole 2 "are preassembled by adhesively uniting them at their toe portions only. The insole 1 has a ball portion 3 formed of a cushion material for example a cor-k composition, and a shank portion 4 and a heel portion 5 formed in 'tegrally of a bendable, yetfirm and relatively hard material for example fiber board or leather.

The shank and 'ball portions 'are adhesively joined in a V-type dove tail joint 6 so that the entire insole isessentially of integral construction.- Edges of the shank and heel portions of the insole are finished with a stitched-on "binding 7. The

-outsole 2-is formed of flexiblefirrn wear-resisting mate- -rial for example, leather or aplastic or rubber composition: and comprises a ballportionS, shank portion 9 and a tonguelike heel portion 19' of reduced Width. The insole and outsole are united only at the toe and fonward portion of the ball, the rear ball portions and shank portions being left free: The'ball portion of the outsole is larger than that of the insole and projects beyond the edges of theinsole approximately to% inch. The'shank porti o'ns of 'tlieinsole and outsole are approximately the samewidth. cover'11 of upper'material,for example leather; fabric or plastic, overlies the toe portion of the" insole and the forwardly "projecting toe portion of 2,954,766 Patented Dec. 29, 1960 An upper 13 (Fig. 1) is fabricated from suitable upper material for example leather, fabric or plastic cut accurately to a selected pattern and comprises a vamp portion 14 and quarter portions 15. The upper is shown as being fabricated from two main pieces of material joined' by a strip 17. A heel strap 18 attached to the rear of one of the pieces is received by a buckle 19 mounted on the upper rear portion of the other piece. Edges of the upper that are exposed in the completed shoeare suitably finished, for example by stitched binding 20. Theupper preferably has a lining 21 (Fig. 7) and heel lining 22.(Fig. 4) formed of fabric, light leather or other suitable material. The quarter portions of the upper are cut to provide a lasting allowance 23 (see also Figs. 5 and 8). The vamp portion 14, on the contrary has no lasting allowance, opposite side edges 24 being cut accurately to pattern so that in the completed shoe (Fig. 7) they require little or no trimming.

The upper is shown as further com-prising mudguard strips 25 (Figs. -1 and 2) secured to the opposite side edge portions of the vamp 14. The mudguard strips 25 extend from the open toe 26 to the junction of the vamp 14 with quarter portions 15 and are accurately cut from suitable upper material, being substantially straight and of uniform width except for tapered rear end portions 27. The strips 25 overlie side edge portions of the vamp 14 and are securely united with the vamp, for example by adhesive and by stitching 28. The outer edges 29 of the mudguard strips 25 project approximately inch beyond the lateral edges 24 of the vamp 14, it being understood that this distance may vary by perhaps A; inch according to the particular style and size of the shoe being made. In cutting the mudguard strips 25, a slit 30 is formed approximately /2 inch from the rear end of the strip and extends inwardly from the outer edge 29 to approximately the respective lateral edge 24 of the vamp. The mudguard strips 25 are unlined. It will be understood that instead of having separate mudguard strips as shown in the drawings, the corresponding portions may be formed integrally-with the vamp portion of the upper.

Afiter completion of the upper as described, the upper 13 including the attached mudguard strips 25 as illustrated in Fig. l, is assembled with the insole-outsole unit shown in Fig. 3. To facilitate assembly of the upper and sole units, the inner faces of the projecting mudguard strips 25 and the upper surfaces of the projecting outsole portions are coated with adhesive to make them tacky. The projecting portions of the guard strips forward of the slits 30 are bent outwardly and pressed into place along the outwardly projecting edge portions of the sole so as to hold the upper temporarily in place on the sole unit as illustrated in Fig. 4. The sole is provided with nicks to indicate where to place the upper. The vamp portion of the upper is then permanently attached to the ball por tion of the sole by stitching 32 which passes through the outsole and the outturned edge portions of the mudguard strips 25 and extends from one of the slits 30 forwardly, across the toe and then rearwardly to the other of the slits 39. The slits 30 thus define the beginning and ending of the stitching and facilitate the stitching operation. It will be noted that at the toe of the shoe, the stitching 32 passes through the forward portion of the material 11 covering the toe portions of the insole and outsole, thereby further securing the covering material. As the edges of the vamp portion 14 and line 21 are not turned outwardly and stitched to the outsole with the guard strip 25, the edge of the sole and the finished shoe has a lighter, neater appearance and no moisture can soak in through the lining since the edge of the lining is not exposed. -Moreover, since the 'vamp portionof :the uppenisino t lasted, the ball portions of the outsole and insole are not separated by lasting allowances of the upper but come directly together to provide a smooth, flat, lightweight and fiexible construction. Moreover, the edges 24 of the vamp are not exposed but are held between the guard strips 25 and the edges of the insole 1. The insole is sufficiently thick, for example A; inch, to form with the mudguard strips a recess to receive the edges of the vamp. The inside of the upper as well as the sole thus presents a smooth surface which contributes to the wearers comfort.

The upper and sole unit are assembled and stitched together as illustrated in Fig. 4 without lasting. A last L is then inserted in the partially completed shoe and the shank portion of the insole is temporarily tacked to the last. The lasting allowances 23 of the quarter portions of the upper are then lasted over the shank portion of the insole (Fig. 5) for example by a cement lasting process. During the lasting of the quarter portions of the upper the shank portion 9 of the outsole is bent up out of the way so that it does not interfere with the lasting operation. The lasting of the instep portion of the upper makes it possible to shape the shoe accurately to the last and obtain a much better fit than is possible with conventional stitched-down shoes. In stitched-down shoes, it is difficult to obtain proper fit and prevent bulging of the upper particularly in the shank portion of the shoe. This difiiculty is overcome by the method in accordance with the invention since the lasting of the quarter portion assures accurate molding of the upper. Moreover, by eliminating in the shank portion of the shoe, the laterally projecting sole and out-turned edges of the upper that are typical of stitched-down construction, it is possible to reduce the width of the shank and give it a trim, smart appearance. As seen in Fig. 8, the shank portions of the insole and outsole are of substantially the same width. Although the lasting allowance 23 of the quarter portion of the upper is interposed between the insole and outsole, the material is of single thickness and does not objectionably thicken the shank portion of the shoe.

In the operation of lasting, the quarter portions of the upper, the rear end portions 27 of the mudguard strips 25 are brought in over the insole so that they point inwardly toward one another in a direction transverse to the length of the shoe, and approximately perpendicular to the edges of the sole. The rear end portions of the guard strips are secured in place, preferably by adhesive and are securely held between the insole and the outsole;

The bringing of the rear end portions of the mudguard strips in toward one another at rear of the ball portion of the shoe as shown and described, further assists in shaping the upper in the important transition zone where the quarter portion merges into the vamp. It further assists in giving the shoe a neat and streamlined appearance and increases its strength and durability. The slits 30 in the mudguard strips provide a smooth and strong transition from one type of construction to the other, avoiding the possibility of strain and breakage.

The inturned rear end portions 27 of the mudguard strips 25 and the lasted edge portions 23 of the upper are then roughened, a steel or other shank reinforcing the strip 33 (Fig. 8) is placed between the shank portions of the insole and outsole and the rear ball and shank portions of the outsole are cemented down, using a suitable press. If a wedge heel is to be used, no reinforcing shank is required. The shoe is preferably left on the last 2 or 3 days to become molded to the last. A heel 34 (Fig. 6) is then afiixed to the heel portions of the insole and outsole, the tongue-like portion of the outsole being received in a recess in the heel. Sponge rubber padding 35 (Fig. 8) is positioned to cover the heel and shank portions of the insole and a sock lining 36 is cemented in place.

The shoes made in accordance with the method of the invention have a dressy appearance and yet are extremely serviceable and comfortable to wear. They thus help to rsolve the dilemma with which women have long been faced as to wearing shoes that are comfortable or shoes that are stylish.

While a preferred embodiment of the invention has been shown and described, it will be appreciated by those skilled in the art that the method in accordance with the invention can be used to produce a considerable variety of shoes. The invention is thus not limited to the manufacture of the particular embodiment shown by way of example in the drawings.
