' AND WOOLEN MAND'FACTUBING COMPANY, 0F MISHAWAKA, INDIANA, A. CORPORA- TroN 0F INDIANA' f RUBBER SOLED SHOE .AND METHOD OF MAKING- SAME Application led November 1, 1930. Serial No. $2,631.

My invention relates to improvements in shoes, and the method of making same, wherein a rubber sole is vulcanized onto the upper and has a foxing extending upwardly therefrom around and attached to the lower portion of the upper, this invention having reference more particularly to the utilization of the foxing as the means for lasting the upper to the sole.

The principal objects of'my invention are to simplify the construction of rubber soled shoes of the character above referred to; to minimize the amount of materials required;

`to avoid unnecessary layers of material and undesirable thickness along the lasted edge; to enhance the appearance and increase the serviceability of the shoe, and in general to facilitate the manufacture, improve the construction and minimize the cost of rubber soled shoes of the type to' which my invention relates. v

In the methods commonly employed in manufacturing shoes, such for example as athletic shoes, wherein-a rubber sole is vulcanized onto a fabric upper, it is customary vto last the edge of the upper over the insole and in addition to provide a foxing which is cemented around the llower portion of the upper and turned in over the lasted edge thereof. This not only entails considerable work which must be performed very care-l y fully in order to insure an ade uate coatino b of cement of definite width around the lower portion of the upper,-to apply the foxing strip evenly over this cemented area and roll it` down into firm adherence .-and to turn the edge in properly over the lasted edge of the upper, but moreover it is practically impossible. even with the utmost care, to avoid the presence of some cement on the upper above-the foxing strip and this necessarily detracts from the neatand finished appearance of the shoe. The edges of the cemented foxing also tend to loosen in service and this not only impairs the appearance of the shoe but shortcns the life thereof. Furthermore,

thelasting of the edge of the upper over the insole and the turning in'of the lower edge IANA, ASSIGNOB TO MISHAWAXA RUBBER sole which must be compensated for by extra filler but there is also the additional wastage of stock due to the unnecessary provision of both the upper and the foxing. strip with corresponding edge portions which are adapted to be turned in and lasted to the sole. Y

In my preferred construction thelasting edge of the upper is entirely omitted, said upper being merely of suiiicient length to extend down around the marginal edge of the inner sole substantially to the under face of the latter. and this upper has a foxing Strip secured therearound and projecting sufficiently below the lower edge of the upper so'that this projecting edge lofthe Lfoxing alone servesv asthe means for lastingthe upper to the sole.A suitable material, as for example, a rubber faced fabric. which will insure a permanent and dependable connection of the upper'with the sole and it may be secured' to the upper in. any convenient manner. preferably by stltching the foxing along its upper edge to the shoe upper as this insures a strong and dependable connection and avoids th un# sightly presence of cement on the upper whichv almost necessarily occurs ifcement is used for this purpose. i

In some cases, however. it may be desired to reinforce or strengthen the connection of the upper and sole at places where excessive strains occur. as for example. at the heel where the shoe may have a stifl` counter which tends to cut and loosen up the foxing strip, and this may be accomplished b v proriding the upper at or around the heel portion with an extended edge for lasting over the insole in the 'usual mannen,` the lasting edge of the upper being omitted along the shank. vamp and toe port/ions -of the upper. or this reinforcing mayr be accomplished by This foxing strip is of increasing the strength of the foxingl strip where additional strength is required.

While I prefer. for the reasons above indicated. to stitch the foxing to the upper, the foxing may be attached merely by cementing same to the upper with the lower edge of the foxing projecting sufficiently beyond the lower edge of the upper to serve as the means for lasting the upper to the insole, or the fox-ing may be stitched to the upper and also cemented thereto in which case the cement ing may be confined to a narrow width along the lower edge of the upper or may be used over the entire surface underneath the foxing. Various arrangements of stitching may also be employed, for example, the upper may be stitched along its lower edge to the foxing which latter is stitched along its upper edge to the upper, and moreover this stitching of the foxing to the upper may be used to advantage in rubber shoes made in accordance with the previous practice wherein the edge portions of both the upper and foxing are lasted over the insole, as the stitching insures a secure and permanent attachment of the foXing to the upper and avoids loosening up of the foxing in service which impairs the appearance and shortens the life of the shoe.

In order that my improvements may be more fully understood, I have shown in the accompanying drawings, an athletic shoe constructed in accordance with my invention, and in said drawings:

Fig. 1 is a perspective view of the shoe taken from the side;

Fig. 2 is an enlarged detail sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a. similar sectional view showing a modification;

Fig. 4 is a similar sectional view showing another modification; and

Fig. 5 is a sectional View showing the arrangement of the upper and insole preparatory to the lasting of the foxing onto the insole.

Referring to the drawings the reference numeral 1 indicates the shoe upper which preferably ing 3, and a tongue 4 which terminates at its lower end in a toe portion 5 which is stitched between the forward ends of the side portions of the upper. Lacing strips 6, a toe cap 7 a heel counter 8 and ankle strips 9 are also provided and stitched to the upper in the usual manner. This upper structure, however, instead of being made of the usual length to provide a marginal portion around the lower edge for lasting over the insole, is made merely long enough so that when placed on the last for assembling the sole, the lower marginal edge of the upper extends around the marginal edge of and terminates substantially at the outer face of the insole. In other words, the marginal edge portion of the upper that is usually provided for lasting over the insole is omitted in mv present construction, and in lieu thereof I provide the upper with a foxing strip around and extend- .ing beyondthe lower edge of the upper so that the extended edge portion of the foxing serves alone as the means for lasting the upper to the insole.

consists of an outer layer 2 of' canvas or other suitable fabric, a fabric lin- This foXing strip which is made of suitable material to insure a permanent and dependable connection, preferably consists of a strip 10 of frictioned fabric with'a facing 11 of rubber composition on the outer side and is stitched along its upper edge as at 12 (two lines of stitching being preferably employed) to the upper so that sufficient of the foxing strip projects below the lower edge of the upper for satisfactorily lasting over the insole.

The foxing may be additionally secured to the upper, if desired, by stitching the upper along its lower edge to the foxing as indicated at 13 in Fig. 3, or any or all of the surface of the upper underneath the foxing may be cemented to the foxing as at 14 in Fig. 4, the stitching, however, being preferred as it may be conveniently accomplished as the other parts of the upper are stitched together.

After the upper has been prepared as above, with the foXing 10-11 attached thereto, it is applied on a last in the usual manner and the insole, which in my present construction consists of a layer 15 of rag stock compound with an adhesively attached fabric sock sole 16, is placed in position with the edge portion of the upper overlapping the edge face of the insole and terminating substantially at the exposed face of the insole substantially as shown in Fig. 5. The projecting edge of the foxing lO--ll is then turned inwardly over the edge of the upper and lasted onto the inner sole, the expose face of which has previously been coated with rubber cement so that the foxing will adhere thereto, and the remainder of the sole is then assembled. In the illustrated construction this comprises a middle sole 17 of rag stock composition with fabric facing 18 adhesively attached to what constitutes the bottom face thereof in the finished shoe, which said middle sole is adhesively attached to the inner sole layer 15 and the inturned edges of the foXing, said parts having been previously provided with a coating of rubber cement in the usual manner for this purpose. The exposed face of the assembled sole structure is then coated with rubber cement after which the outer sole 19 of rubber composition is cemented in place with the edges thereof fitted along and secured t'o the foxing slightly up the side of the latter substantially to the top of the inner sole somewhat as shown in Figs 2, 3 and 4 and this, in case the bottom edge of the upper is stitched to the foxing as at 13 in Fig. 3 covers and protects the stitches 13. After the shoe has been assembled as above, it is vulcanized in the usual manner.

With this construction the upper is not attached directly to the insole but merely extends down around the marginal edge of the insole substantially to the bottom face of the latter and is lasted to the insole by the proya shoeof greatly improved appearance which is produced more readily and with less labor than previous shoes of this pharacter.
