8 Claims.

This invention relates to improvements in shoes and shot bottom units andit is concerned more especially with so-called platform shoes of the type in which a welt is associated with e. middle or platform sole for producing the effect of a platform between the upper and the outside.

In platform shoes of the above-mentioned type, as heretofore constructed, the margin of the mid-- dle or platform sole extends between the welt and the outsole and a strip of binding material is em-. ployed to cover both the edge of the middle sole and the edge of the welt, the binding strip usually having its upper edge interposed between the welt and the upper and secured in place by the inseam stitches.

One object of the present invention is to provide a platform welt shoe of improved construction which can be manufactured more economically than has been possible heretofore andwhich has, in addition to the advantages of other shoes of this type, certain novel features which add substantially to the attractiveness and stylish appearance of the shoe.

With this object in view the invention, in one aspect, provides a shoe bottom unit consisting of a middle or platform sole, and a welt which is secured to the margin of the sole and is so disposed relatively thereto that a novel and distinctive platform effect is produced when the unit is incorporated in a shoe. In the embodiment of the invention herein illustrated the welt underlies the marginal portion of the middle sole and extends outwardly a substantial distance beyond the sole edge and a relatively thin leaf or lip, in-

tegral with the body of the welt, covers the edge of the sole and overlaps the upper side thereof. Since preferably the welt is made of leather and the lip of the welt has an outer grain surface, an attractive finished appearance is imparted to that portion of the platform sole which will be exposed to View when the sole is in a shoe. The body portion of the welt which extends outwardly beyond the sole is adapted to receive the outseam stitches which are used to attach the outer or tread sole to the shoe and this portion of the unit will simulate the appearance of the exposed portion of the welt in a conventional Goodyear weld shoe.

Invention is also to be recognized as residing in a shoe having my improved platform unit incorporated therein, the shoe embodying certain novel features of construction hereinafter described and claimed.

erence to the accompanying drawing, in which: Fig. l is a fragmentary perspectlve View of a strip of welting in process of being prepared for attachment to a middle or platform sole;

, Fig. 4 is a view, partially in section along the line IV--IV of Fig. 3 and partially in perspective,

of my platform unit; and

Fig. 5 is a fragmentary View, partially in crosssection and partially in perspective, of a shoe in which my platform unit is incorporated.

In the embodiment of my invention illustrated in Figs. 3 and 4 of the drawings, my improved platform unit comprises a middle or platform sole l0 and a welt I2 which is secured to the margin of the sole, the welt extending entirely around the sole and projecting a substantial distance outwardly beyond the sole edge. The sole 1 0 may be made of any suitable inexpensive substance, such for example as any of the well-known leather substitute materials, or it may be made of cushioning material, such as felt, sheet cork, cork composition or the like. The welt [2 comprises a main or body portion [4 to which an outsole may be directly attached and a relatively thin flap or lip [6 which is integral with the body portion [4 and which covers the edge of the platform sole and the adjacent upper marginal surface thereof. The welt I2 is preferably made of leather of good quality'and has a finished grain surface I8 upon its upper side. As indicated in Fig. 1, the lip l5 maybe made advantageously by forming. an edge slit or incision 20 in a welt strip He. The welt is thus split from its inner edge so that a lower flap or lip is formed beneath the lip I6 for attachment to the lower side ofthe platform sole. A trimming cut 22 may also be made in the lower lip of the welt strip beneath the slit 20, the slit 20 and the cut 22 severing a waste piece 24 from thewelt strip so that the lip IE will be wide enough to cover the edge and adjacent upper surface portion of the platform sole l0 without extending inwardly beyond' the inner edge of the lower lip., As shown in Fig. 2, the welt I2 may be further prepared for attachment to the middle sole HJ by having the lip l6 raised and a coating 26 of a suitable adhesive, such as latex, applied to the surfaces of the lip and the body of the welt which are The invention will now be explained with ref- 55 to engage the sole It. After having been thus prepared, the welt I2 is secured to the sole I0 by pressing the inner body portion of the welt against the lower marginal portion of the sole and pressing the lip it against the ed e and upper marginal portion of the sole as the strip is being laid progressively around the sole. As shown, the opposite ends of the welt may be disposed in butted relation, as indicated at 28 in Fig. 3. A platform welt combination, such as shown in Figs; 3 and 4, is thereby formed which is adapted to be applied as a unit to the bottom of a shoe. As shown, a stitch groove 30 may be formed in the lower lip of the welt for receiving stitches for attaching the unit to the shoe.

As shown in Fig. 5, my improved platform unit I may be secured to a shoe by means of stitches M which extend through the platform or middle sole l0 and the insole 36 of the shoe and through the margin of the upper 38 which, as shown, is disposed in overlasted position upon the insole. It will be noticed that the stitches 34 extend also through the lower lip of the welt l2 and also through the lip 16, thus securely and permanently attaching the welt to the middle sole, the upper and the insole and effectively holding the lip H5 in place against the edge of the platform sole. The outsole 60 of the shoe is secured by outseam stitches 42 to the body portion Id of the welt which extends outwardly beyond the sole edge. The shoe thus produced has an extension edge welt and outsole margin structure similar to that which is a characteristic feature of a conventional Goodyear welt shoe and, in addition, a novel and distinctive platform effect is produced where the covered edge of the middle sole appears between the upper and the body portion of the welt. The attractiveness of this portion of the shoe is enhanced by the facts that the covering on the middle sole is integral with the body of the welt and that both of these parts have a finished grain leather surface. Moreover, the shoe may be made economically because of the unitary construction of the platform sole and the welt which enables these parts to be secured to the shoe by a single throughand-through stitched seam sewn by a straight needle sewing machine.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1.
