Other objects of this invention will be apparent from the drawing and'from the description thereof, or will be specifically indicated therein.

The inventionV is not intended to be restricted to the construction and arrangement of parts herein shown and described,vnor to the various details thereof, as the same may be modified in various particulars without departing from the spirit and scope of the invention, as defined by the claims, some practical embodiments of which have been herein illustrated and described without attempting to show all the various forms and modifications in which'the invention might be embodied.

On the drawing, wherein is disclosed a preferred embodiment of the invention, Fig. 1 is a perspective view of a shoe, the sole and heel of said shoe being removed to 'xdisclose the manner of assemblyT of theV parts embodying my invention thereinto. Fig. 2 is a view similar to Fig. l with a modified form of my invention applied to the shoe. Fig. is a longitudinal sectional view of a portion of the shoes of Figures l and 2. Fig. i is a perspective view of a detail of my invention. Fig. 5 is a View similar to Fig. 4 of a modified form of said detail.

A shoe 10 having the conventional construction of upper 12, insole 14, welt 16, counter 18 and lining 20 is shown on the drawing. In thisconstruction, the upper and lining are seen to have been formed around the counter, which preferably is molded to the form of the foot, such upper and lining being tacked or otherwise secured to the insole with which the counter .is assembled. Along the sole and shank porthe welt are received together on the outer portion of the insole and are secured thereto by sewing or like method.

By this construction there is provided a on the bottom and the inner edges'of the upper and welt at the side portions thereof. At; the heel end of the insole, the lining and the upper are generally of such thinness that the cavity they form is'inappreciable. so that the condition of shoe` formed up to this point, is substantially flat at the heel re'gion.

Before the sole is applied to the welt and assembled with the heel portion of the shoe, it has become customary to iillthe sole portion of the cavity 22, just described,'with some waterproofing material, such as ground ycork mixed withsome suitable tar or pitch product having substantialy waterproofing qualities and suiicient adhesive properties to hold in properly associated relation the cork mixed therein and the other portions of the shoe withwhich 1t comes in contact. At the shank portion 24 of the shoe, which is substantially at the instep of the foot and, therefore, the position mostly desired to be protected against the ordinary dangers of breakdown, means are provided to give rigidity to this portion. I

ln the construction herein shown, a member 26 is used and is seen to consist of a heel section 2S and a shank section 30, substantially integral with each other. The member is preferably made of leather or some similar material and is preferably formed from one piece of such material so that the sections above noted will, at all times, be retained rigidly relatively each other.

llt will be noted that the heel section 28 is of substantially the same extent as that of the counter around which the upper is formed and of the insole at the heel portion of the shoe, while the shank section 30 at the heel end thereof is of substantially the same width as the distance between the secured welts, such shank section following closely the shaping between such welts. The edges 32 at point 3d of the junction of the heel and the shank section 30 of the member 26 are preferably skived to permit the ready und neat assembly of the member with the heel and shank portion of the insole and with the Counter. The skived edges 32 permit the positioning of the member with the heel section thereof slightly overlapping the skived ends of the welt, thus, when assembled, providing an appearance of uniform thickness substantially continuously around the body of the shoe. Skiving the edges 3G of the shank section permits the latter to fit smoothly into the cavity 22 and also opens up the porous portions of t-he leather to the action of the adhesive properties of the filling material deposited in such cavity, which then serves further to assure the retention of the member in position in the cavity.

A strap 38, preferably of spring steel, has the ends thereof anchored to the member in such manner that the length of the strap between the anchor points is slightly greater than that of the length of-leather lying between the anchor points. Since the strap will be positioned neXt to the insole and between the insole and member 26, pressure, as finally applied to the strap when the weight of the body of the wearer istransmitted thereto, will tend to distend the same and will thereby attainthe result of assuring that the sh ank section 8O will be retained rigid.

The surface of the member 26 which faces the insole and other portions of theshoe with which it is assembled is preferably the smooth outer hard skin of theleather so that the latter skin will be positioned directly in contact with the counter and the other por-` tions of the heel of the shoe. This skin has well-known properties of substantial rigidity in comparison with the other portions of the leather, and the manner of positioning de- :scribed assures that the counter and associated portions of the shoe will be restrained substantially against any spreading, due to the solid backing thus provided.` In the final assembly operation, the heel portion of the member will be nailed, together with the heel portion of the sole 37 and the heel 39 of the shoe, to the insole and counter, with which these elements will then be firmly anchored. Y

It is possible to construct the two sections of similar or distinctly different materials, such as two distinct portions of leather.4 In such case, the'edges of the two sections, at their junction sector, would require supplementary skived surfaces or the like to permit the joining, by gluing or the like, of the sections into a substantially integral member without the production of any decided nonuniformity in the thickness of the material at such junction sector.

In the modilication shown in Figp, the heel section 40 and the shank section 42 are made of separate portions of leather or similar material, and the adjacent portions 44 and 46 of the sections, which are linally to be united, are skived in such manner that the hard outer layer 48 of the heel portion will iinally be on the reverse side from that of the hard outer layer 50 of the shank portion. Bythis arrangement, the soft, absorbent side of the leather is presented at the shank portion to coact with the adhesive illingrmaterial, and the hard outer surface will be located at the heel portion in such manner that the proper coaction with the counter will be obtained as set forth above.

In the modification of Fig. 5, notches 52 are extended back through the heel portion substantially at the side edgesV of the shank portion and are adapted to receive therewithin the inseam formed by the junction of the insole, the welt and the upper. The skived edges 54 of the extending portions of the- Y heel section are positioned in such manner that they may overlie when the shoe islbeing worn, the skived ends of the Welt, as appears i of the heel end of the sole form to the counter and insole, a number of distinct steps are eliminated from the operation of manufacture when the principles herein taught are utilized.

Likewise, due to the rigidity resulting fromthe firmly anchored shankportion, a product results which compares'ifavorably with the custom made shoe in form and appearance, such product continuing to retain its `form after it has been put to the test of L use.

As it appears that many changes could bemade in the construction and process herein involved, and `many widely different emsaid insole, substantially the entire sole portion of said cavity lbeing tilled with 1an adhesive waterproofing material, anda member secured to, :and externally of ,said eupper.,
