BOOT AND SHOE Application filed August 6, 1930, $eria1 No. 473,327, and in Great Britain August 30, 1929.

This invention relates to boots and shoes and has for one of its objects a mode of manufacture which avoids the use of tacks for permanently securing the uppers to the in- 5 soles prior to the application of the outer soles and heels. If tacks are not employed, the boots and shoes will be rendered more flexible in use and lighter in weight than footwear where tacks are employed, and will eliminate any source of discomfort to the wearers of boots and shoes, occasioned by the tacks either hurting the feet of the wearer or destroying the hose on the wearers feet.

This invention comprises a method of manufacturing a boot or shoe which includes the following steps (a) Lasting an upper and insole so that the edge of the upper overlaps the insole and is secured to the last with the insole by means of tacks or the like.

' (b) cementing the said edge of the upper to the insole around the whole thereof.

(a) Removing the tacks and stitching the edge of the upper to the insole through the combined substances of the said edge and insole prior to the application of the outer sole and heel for at least that portion of the upper located at the heel seat.

The stitching of the portion of the upper which overlaps the heel seat to the insole ensures a solid foundation for the heel and materially assists in preserving the structure of the boot or shoe whilst the heel foundation is sewn thereto, and also prolonging the life of the boot or shoe when in use.

After the operation above described for attaching the upper and insole together, the usual filling is applied to the insole between the cemented portions of the upper, and the outer sole and heel foundation are then secured in position thereon in the usual manner, for example, the McKay method of sewing, the edge of the insole having been split into two portions, one of which receives the stitching for securing the outer sole in position and also the stitching around the heel seat, whilst the other portion of said split edge serves to conceal such stitching, and protect the foot of the wearer therefrom. The usual sock may, however, be applied within the boot or shoe to cover the insole if desired.

To enable the invention to be fully understood the same will now'be described with reference to the accompanying drawings,.in which T Figure 1 is a bottom plan View of a boot 0r shoe upper applied to an insole in accordance with the invention,

Figure 2 is a section on the line 22, Figure 1, but showing inposition the last upon which the boot or shoe is made, t

Figure 3 is a View similar to Figure 2, bu illustrating a prior stage in the manufacture of the boot or shoe, and 7 Figures 4, 5 and 6 are also views similar to Figure 2 but illustrating subs-equent'stages in the manufacture of the boot or shoe.

Referring to Figures 1 to 3 ofthe drawings, the upper a and insole b arearranged on a Wooden last 0 in the known manner and the edge portion cl of the said upper is drawn over and overlaps the edge of the insole and is secured temporarily thereto and to the last by tacks c, e as indicated in Figure 3, the tacks being preferably only partly inserted into the last. Cement is then applied between the said overlapping edge portion 03 of the upper and the opposed face of the insole b so as to secure the said edge to the said face; After the cement has set, the tacks e, e are removed'from the upper, insole and last, so that the upper and insole present the an pearance indicated in Figures 1 and 2, in which they are entirely free from tacks and secured together only by the cement.

The last is removed and the portion of the upper a which overlaps the heel seat portion of the insole, is then stitched, as indicated at 7, Figure 1, to ensure greater solidity at this part of the boot or shoe.

After the attachment together of the upper a and insole b as above described, the usual adhesive filling 9, Figure 4:, is applied to the insole b in the spaceenclosedbythe edge ofthe upper or and then the outer sole h and heel foundation (not shown) are secured in position to the connected upper and insole, for example, by the McKay method of stitching.

The edge of the insole b is preferably split to form two portions 2', j, Figure 5, the portion 11 receiving the stitches 70 which secure the outer sole h in position and which stitches may be continued round the heel seat if desired, whilst the portion 7', after the formation of the said stitches, is cemented to the portion 2' to conceal the said stitches, as indicated in Figure 6, and affords a smooth surface around the edge of the insole. The usual sock may then be cemented to the insole if desired.

From the'foregoingit will be understood that not only is a boot or shoe, manufactured as described, more flexible and lighter than boots or shoes where tacks are employed for securing the upper and insole together, but

such method of manufacture need not cost any more and may even be cheaper than the ordinary method when tacks are used.

What I claim is:

1. A method of manufacturing a boot or shoe which includes the following steps z- (a) lasting an upper and insole so that the edge of the upper overlaps the insole and-is secured to the last with the insole by means of tacks, (Z2) cementing the said edge of the upper to the insole around the whole thereof, and (c) removing the tacks and stitching the said edge of the upper to the insole through the combined substances of the said edge and insole prior to the application of the outer sole and heel for at least that portion of the upper located at the heel seat.

2. A method of manufacturing a boot or shoe which includes the following steps (a) lasting an upper and an insole so that the edge of the upper overlaps the insole and is secured to the last with the insole by means of tacks, b) cementing the said edge of the upper to the insole around the Whole thereof, (0) removing the tacks and stitching the said edge of the upper to the insole through the combined substances of the said edge and insole prior to the application of the outer sole and heel for at least that'portion of the upper located at the heel seat, and, (d) stitching an outer sole and heel foundation both to the edges of the upper which overlap the insole and to the insole.
