14 Claims.

My invention, which relates to improvements in shoes of the type forming the subject matter of applicants United States Letters Patent No. 2,040,043, issued May 5, 1936, and has among its objects a shoe which supports the foot in an improved manner, will be best understood from the following description when read in the light of the accompanying drawings of several embodiments of the invention, the scope of which latter rwill be more particularly pointed out in the appended claims.

In the drawings:-

Fig. 1 is a side elevation of a shoe constructed according to the invention;

Fig. 2 is a plan according to Fig. 1;

Fig. 3 is a bottom view'of the shoe according to Figs. 1 and 2 before the sole is applied;

Fig. 8 is a side elevation of the shank stiffener according to Fig. '7;

Fig. 9 is a section on the line Q--Q of Fig. 7;

Figs. l0, 11 and 12 are views, corresponding to Figs. 3, 4 and 5 respectively, showing a modified form of shoe;

Figs. 13 and 14 are views, corresponding to Figs. 3 and 4, showing a further modified form of shoe; and

Fig. 15 is a plan of the two shank stiffeners in assembled relation employed in the modifications shown by Figs. 10 to 14.

Referring particularly to Figs. l to 9 of the drawings, the shoe illustrated is provided with an insole l which at the inner edge of the shank portion thereof is formed with an upwardly extending overhanging portion 3 for supporting the in ner longitudinal arch of the foot. The insole is channeled, as indicated schematically at 5 in Fig. 5, in more or less the usual manner except that the channel passes beneath the base of the overhanging portion 3 instead of following the edge of the insole adjacent that portion.

As illustrated, the insole is split parallel to the upper and lower faces thereof, as indicated at l.

In this split is placed a shank stiffener 9 of thin flexible material such as tempered clock steel. As illustrated in Figs. 7, 8- and 9, this shank stiffener is longitudinally and transversely curved to conform to the desired shape of the shoe and is (Cl. Sii-8.5)

provided with an upwardly extending overhanging portion l I, which is received in the upwardly extending, longitudinally and transversely overhanging portion 3 of the insole, the body of the shank stiifener being beneath the shank of the foot when the shoe is worn. By this construction is provided a resilient support at the inner side of the arch of the foot.

As shown, an auxiliary shank stiifener i3 is provided which extends longitudinally of and conforms to the shape of the medial portion of the shank of the insole, this stiffener being relatively rigid and being placed beneath the insole as illustrated in Fig. 4. For holding the parts in assembled relation tubular rivets l5 may be provided which extend entirely through the insole and suitably formed perforations in the twoshank stiifeners, these perfcrations for the shank stiifener B being indicated at i6 in Fig. '7 and registering perforations being formed in the shank stiiener I3.

The uppers in the shoe illustrated comprise the upper leather Il and an inner canvas or leather lining I9. Preferably on the inner side of the shoe adjacent the shank and between the upper leather and lining is inserted a flannel sheet 2 l The shoe in this embodiment of the invention is also provided with a counter stiifener 23, preferably of stiff leather, which at the outer side of the shoe has the forwardly extending portion extending to approximately the forward end of the heel portion, and at the inner side of the shoe has the forwardly extending portion 2l' extending to the forward end of the overh'anging portion 3 of the insole. positioned between the canvas lining i9 and the flannel sheet 2l.

The Welt 29, which is coextensive with the channel 5 in this modification of the invention, is secured to the insole by a row of stitching 3i. This row of stitching, as clearly illustrated by Fig. 4, also secures to the insole the edge portions of the upper leather, lining and 'flannel sheet, and the edge portion of the extension 2'! of the counter stiffener. After the welt is secured to the insole. and the filling 33 is added, the sole 35 may be secured to the Welt by the row of stitching 3i illustrated in Fig. 4.

It will be observed that in the construction of the shoe just described all the stitching for securing the parts to the insole adjacent the overhanging portion 3 thereof is below the shank stiifener 9, and that consequently the latter need not be provided with perforations for permitting passage of stitching, such as stab-stitching,

The counter stiffener, as shown, is

through the insole for securing .either the welt or the sole thereto.

The modification of the invention shown by Figs. l0, l1 and 12 is similar to the modification just described except that the insole is not channeled beneath the overhanging portion 3, nor is the insole split, the thin iiexible shank stiffener 9 in this modification being positioned immediately below the insole and being provided with a row of perforations 39 through which extends stabstitching 4l for securing the sole, counter stiffener and upper parts to the insole adjacent the overhanging portion 3 thereof.

In this latter modification the channel of the insole, as indicated schematically in Fig. l2, ex-l tends from a point at the forward end of the overn hanging portion 3 around the front end or toe portion of the shoe to a point at the forward end of the heel portion of the insole on the outer edge thereof. The welt 29, as indicated in Fig. 10, is Coextensive in length with' the channel, and is secured to the insole by a row of stitching 63 in the usual manner as indicated in Fig. 1l.

Beneath the overhanging portion of the insole, where there is no welt, the upper leather and lining Il have secured thereto, by a row of stitching 45, one or more canvas webs 4l, three of which sewed together at their adjacent edges are shown. These webs extend across the insole to the outer side thereof where they are secured to the insole by the welt stitching 43. This web or webs it will be observed hold the portions of the uppers adjacent the overhanging portion 3 of the insole in drawn over relation during lasting and while the welt is being sewed. After the sole is sewed to the welt the row of stab-stitching 4i, preferably consisting of lock stitches, is formed for securing the parts to the insole adjacent the overhanging portion 3 thereof.

As shown in this modification, the auxiliary shank stiffener I3 is placed immediately below the shank stifener 9, and the two shank stiieners preferably are secured to the insole by the tubular rivets l5 which extend entirely through the in* sole, the perforations in the shank stiffeners. and the webs 41. Otherwise there preferably is no connection between the two shank stiffeners.

The modiiication of the invention shown by Figs. 13 and 14 is like that shown by Figs. 10, 11 and 12, except that the welt extends beneath the base of the overhanging portion 3 of the insole and is secured to that base by a row of stabstitching t9, the latter extending through the perforations 39 in the shank stiffener 9', the counter stiffener, and upper parts, while the sole 35 is secured to the welt by a row of stitching 3'! in the usual manner. It will be understood that within the scope of the appended claims wide deviations may be rnade from the embodiments of the invention illustrated and described without departing from the spirit of the invention.
