This invention has to do with shoes and is more particularly concerned with sandals although, as will appear, the principles of the invention are applicable to other types o f shoes.
The invention is concerned more particularly with an improvement in the sole structure and the connection of the upper to the sole structure.
It is an object of the invention to provide a shoe construction including a middle sole wherein a portion of the middle sole is positioned within the connes of a portion of the upper.
It is another object of the invention to provide a shoe structure wherein the heel portion of a middle sole is coni-ined within the quarter.
Another object of they invention includesthe provision of a special shoe construction which inhibits spreading of the bottom portions of the quarter at the heel.
Another object of the invention involves the provision of a sandal type of shoe with an improved attachment for a sandal strap.
In carrying out the invention in practice, a middle sole is formed with its heel portion re duced so as to be substantially flush with the heel portion of the insole. The sandal strap may be in two pieces secured opposite each other by the stitching or other means securing the insole to the middle sole. The lining of the quarter is lasted under the heel portion of the middle sole, and the vcounter and leather or other surface material of the quarter is ilanged outwardly and stitched or otherwise secured to the outsole. The flanged portion forms substantially a continuation of the unreduced margin of the middle sole, which margin is stitched or otherwise securedv to the underlying margin ofr the outsole. By means ofr these stitchings, a trim strip or rand is secured over the quarter flange and marginal portion of the middle sole, and thereafter, if necessary, the outer edge of the shoe is trimmed.
With this structure, one or more heel lifts may be employed without disturbing the manner of securement of the quarter.
If desired, the lining of the upper, such as the quarter, lmay be cement lasted or otherwise secured to the middle sole. Likewise, the manner of securement of other parts may be varied with- .out departing from the principles of the invention.
Further objects and advantages of the invention will appear as the description proceeds.
Thisvinvention (in a preferred form) is illustrated in the accompanying drawing and hereinafter more fully described.
Figure 1 is an outer side elevation of a right shoe constructed in accordance with the invention.
Figure 2 is an enlarged fragmentary sectional view taken substantially as indicated by the line II-II in Figure 1.
Figure 3 is a top plan view of the middle sole employed in the shoe of Figure 1.
Figure 4 is a fragmentary top plan View showing the middle sole superposed by an insole and other parts of the shoe.
Figure 5 is a bottom plan View of the shoe of Figure 1, just prior to application of the heel lift, outsole and trim strip or rand.
Referring now more particularly to the drawing, it will be observed that the shoe chosen for illustrative purposes takes the form of a childs sandal, having a ball strap l and an ankle strap 2 attached to a quarter 3, secured at the upper part of the sole structure designated generally at 4.
The sole structure embodies essentially an insole 5, a middle sole 6 and an outsole '1. The insole is of a form corresponding with the interior of a shoe. The middle sole, throughout the forepart 3 and shank 9 thereof, has substantially the same size and shape as the outsole so as to afford a protective edge beyond the upper, but the heel portion I0 of the middle sole is reduced to substantially the size oi the heel portion il of the insole 5 and is conned within the outturned quarter.
The strap l is preferably in the form of separate strap parts l2, which are positioned appropriately at the ball and sandwiched between the insole 5 and middle sole 5, preferably before the members 5 and 5 are connected. Thereafter, by means of stitching or the like as shown at i3 at the margin of the insole 5, these are secured together. Viewed as in Figure 4, only the marginal portion of the middle sole at the forepart 8 and shank 9 is then visible.
This unit comprising the insole, middle sole and strap parts I2 is placed on the bottom of a last with the insole against the last, and the quarter assembly 3 placed about the sides of the heel of the last with the lower edge of the quarter assembly projecting beyond the heel end of the middle sole. The quarter assembly may have any suitable number of layers of leather, cloth or other desired material. The lining M is folded inwardly over the exposed face of the heel portion I0 of the middle sole as shown at I5, where Vio it is preferably cemented in place, although if idesired, stitching, stapling, nails or other suitablev means may be employed for the purpose.
The adjacent bottom portions of the counter i8 and quarter outer layer l'l are parted from the inturned flange portion l5 of the lining i4 so as to be anged outwardly at I8 and I9, respectively. Because f the curvature of the heel portions, the flanges i8 andV I9 are sltted as at 2B and 2i, respectively, at their curved portions to permit said flanges to have a substantially flat shape.-V This may be resorted toin connection with the inturned portion i5, although it may not be necessary since the lining I4 is quite thin vand flexible lso that it may readily be turned inwardly against the middle sole by folding or pleating at suitable places as shown at 22.
The iiange i8 is formed with its exposed edge is lasted to the exposed face of the middle sole t,
the outsole l, toy the upper sideof which a heel lift 23, if desired, has been cemented or other.-
Vwise suitably secured,is cemented tothe exposed part of the middle sole and the inturned portion i of the lining it, and also to the exposed surface of the counter flange i8. In the exaggerated viewrshown in Figure 2, a space appears between the heel lift 23, the inner edge of the inturned portion i5 of the lining and the middle sole 6. In practice, however, due to the give of theV materials, such space is substantially nonexistent.
Y The flange portions iB and i8 stantially a continuation of the margin of the middle sole rearwardly of the shank portion of the same.Y The structure at this point may be removed from the last, and a preferably leather strip 2li constituting a welt is placed over the outwardly projecting marginal portion of the middle sole and the flange i9 so as to closely embrace the edge of the forepart of the insole :and theV outside of the strap l and quarter 3. This strip 211 is securedin place by a circuitous line of stitching 25 which passes through the strip 24, fianges EG and i8, the margin of the lift 23 andY the margin of the outsole at the heel of the shoe, and also through the margin, of the middle:
various means may be made use of in fasteningv the various parts together, stitching and cementing at the places indicatedeherein has been found to produce a very satisfactory shoe from the standpoint of neatness and durability as well as from the standpoint of ease and low cost of Y manufacture. Y
now afford sub- The layers of the quarter 3 may befof any de-` i sired material. Cloth'or leather may be found manufacture of any kind of shoe including an,V adults shoe, whether it be of the sandal or of Y another type of shoe, The invention, moreover, is not limited to the securement of the quarter,
by themeans and in the manner specified, but
rather contemplates the employment of the same means and method in the securement of other parts of the upper.
rIf desired, instead of flanging the lining inward over the exposed surface ofthe middle sole, the middle sole, instead of being marginally reduced at the heel, could at that point be hanged' upward and the lining of the' upper could be` jsecured Yby cement or otherwise to theY exposed if'ace of the portion so flanged. Howevenl the structure above described is the preferredforni.
With Vthis construction, the number of thickf nesses'through which the heel stitchingv must pass is reduced by the omission ofthe heel flange portion ofthe middle sole, without detracting from the strength, durability and neatness ofthe shoe. Moreover, with this construction spreading of the bottom of the upper isprecluded, so that proper Vside support for the sides and rear ofthe heel of the foot is afforded.
A sockl lining 26 for Athe heel endif desired, for the remainder of the tread ofthe foot may n be provided. l'
If desired, the upper cuter edge of the strip 2li and the lower edge of the outsole l may be beveled as shown at 2l and 28, respectively.
The last may remainin the shoe vuntil after theY hereon otherwise than necessitated by the prior art. Y Y
I claim as my invention;
Shoe construction including an outsole, ank insole, and a middle sole; a quarter said middle solehavingy a heel portion lconiined within Vsaid quarter and having a shank and forepart projectingY beyond the corresponding parts of the insole forA securement to the outsole; means for attaching the middle sole to the insole; sandal l strap means securedin place between the insole Y and middle sole by the kmeans attaching the insole to the middle sole; and said outsole being secured Vto said-.middle sole including the saidi projecting parts" thereof by means independent of the means securing the strap means between said insole and said middlesole.l Y Y OSCAR M. .WILLMAN
