Application September 14, 1948, Serial No. 49,209

UNITED STATES PATENT OFFICE 1 This invention relates to shoes and to their manufacture, and more particularly to childrens shoes, and has for an object to provide a method and construction facilitating the application ofv various orthopedic parts in accordance with specific requirements, and particularly while embodying a desired continuous inner tread and an inner heel end face which merge in a smoothcontour. More particularly the method and construction provide for additional stiffening or support for one side of the heel or shank, usually such being desired on the inner side of the heel or shank portion. Y

For a complete understanding of this invention, reference may be had to the` accompanying drawings in which Figure 1 is a plan view of an innersole member.

Figure 2 is a similar view of a second innersole part provided with a lateral extension or "cookie and an integral inside backstay.

Figure 3 is a view partly in side elevation and partlyin central longitudinal section showing a shoe in inverted position partly assembled andslip lasted and the last removed and with a heel' wedge inserted andthe heel end of the lower innersole member lifted. n

Figures 4 and 5 are detail sectional views on lines'lI-li and 5 5, respectively, of Figures 3 and 6.

Figure 6 is a fragmentary top plan view partly broken away of the structure shown in Figure 2.

Figure l is a fragmentary plan view of a member which is a modication of the member shown in Figure 2. y l

Figure 8 is a view similar to Figure 5 but employing the member of Figure 7.

Figure 9 is a fragmentary sectional view on about the section line -5 of Figure 3, but showing the completed shoe mounted on a special last.

1hReferring to the drawings, at I in Figure 1 is v'shown a exible sole-shaped blank which forms a part of the shoe innersole. In Figure 2 and at 2 is shown an upper innersole layer or lamination which comprises at least a shank and heel portion 3 having an integral rear extension [which forms an inner backstay in the compieted shoe. The portion 4 is stitched into the shoe upper in backstay relation, as shown in Figure 3, and therupper, whichmay comprise a lining 5, and outer 6, and at the heel portion, a counter stiifener l, is secured tothe innersole about at least its forepart and shankuat Ythe sole margin by lines of stitching as shown at 8 in,

turned andl so attached.

At one side, commonly at the outside of the shoe, the innersole member 4 is provided with a widened portion I0 whichextends Vsubstan tially to the outer edge of the innersole blank I and is partly secured by the line of stitching 8 on that side of the shoe to the upper materials coni` prising the lining and outer.` At' the opposite edge,whichis usually on the inside of the shoe,

a curved extension Il is illustrated, this being adapted to form an upward extension within the upper of the shoe and commonly referred to in the art as a cookie This is positioned at the desired point longitudinally of the shoe, oftenV in the shank portion, and it may also extend into the heelportion. This side edge of the upper innersole member 2 is unattached at thiss'tage of the manufacture,` as shown bestin Figures 4 and 5. In Figure 5, a portion of thecounter-stiiener 'I is illustrated, and intheconstruction shown in Figures 3,21, 5,"a'nd 9, the lining 5 as well as the counter stiienr 'I and the' outer 6, have their margins outwardly turned.` The heel end portion of the member I is unatf tached to the upper materials rearwardly ofzthe stitch lines 8. 'y y The shoe so assembled with the upperpmaterials and the innersoleparts is then slip lasted, and if desired, the rear end ofthe innersole' member I and the upper margins are cemented.` The heel end of the shoe is then molded to forni with the margins of the upper materials, in cluding the stiifener, if one is used, a marginal shelf for the attachment of the rear or heel end of the member I which may thereafter be secured in position as by the cement. An outersole I2 is then applied and suitably secured in position, as,'for example, by stitching-, cementing, or the like, to the marginal portions of the innersole member I, the out-turned uppermaterialsand atthe heel portion, if desired, with an interme`` diate wedge member I5.v The sole portion is then iinished by the usual operations, such as edge trimming, edge setting, andthe like.

The last is then removed from the shoe and the unattached edge portion of the member 2 along the edge of the cookie portion II is Vthen liftedl and a wedge filler member I6 is inserted between the cookie, the lowerinnersole member I, and the upper, as shown` in Figure 5. The free' edge portion of the upper innersolemember. 4 is then cemented in position against the wedge, the lower? innersole member I, andthe inside face ofthe" shoe'upper. i l 1. lj;

In some cases it may be desired to employ a last having a cut-out in its sole face to make room for the cookie and the wedge iiller, and where this is used, the operations may be somewhat different since it is then possible to introduce the "cookie and filler in position before the shoe is lasted. Such a last is shown, for example, in Figure 9 at 20, in position in the shoe. Where such a last is employed, after the rear end of the member I has been secured, the wedge may be inserted at the side of the shoe provided with the cookie extension between the innersole members I and 2, and then the wedge, and this extension may be cemented in position. The shoe is then slip lasted with the special last with the cut-out to receive the wedge and the cookie Then the outersole is applied and suitably secured to the shoe either by cement or marginal stitching, or both, as desired, and the sole is nished, after which the last is removed.

In some cases it may be desired'to turn the lining, or the lining and heel stillener inwardly at the heel portion of the shoe, while the outer margin is out-turned to overlie the lower innersole member, as shown, for example, in Figure 8. Or, it might be desired to turn in all the margins at the heel. In such a situation the upper innersole member 2a, as shown in Figure '7, may be employed, this being narrower than the lower irmersole member I so that it may fit within the lining as shown in Figure .8. With this arrangement it will not ordinarily be desired to employ a cookie and ordinarily this innersole member willnot be secured about either margin to the innersole member I and it will be laid in position and cemented before the slip lasting operation. With this construction ordinarily it will not be desired to employ a Wedge in either side of the shoe and consequently a last without any-cutout to receive such elements will be employed. The upper sole member 2 or 2a may extend forwardly within the shoe as far as is desired. In case it extends well into the toe portion of the shoe, it may perform somewhat the function of a sock lining in that it covers the surface of the lower innersole member I Which may then be made of some material such as canvas, cr the like, which would not be desirable for a sole portion exposed on the inside of the shoe. The margin of such a lower innersole I may be cut away or turned inwardly as is known in the art near to the stitches 8,- so that it does not extend to the outer edge of the completed sole member so that its edge will not show in the completed shoe. This is particularly desirable when it is of materialsuch as fabric which will not give the same appearance as the edge of the outersole or upper when nished. 1

From the foregoing description of certain embodiments of this invention it will be evident to those skilled in the art that various further changes and modifications may be made without departing from its spirit or scope.
