Application September 13, 194.6, Serial No. 696,636

'Ihis invention relates to an improved shoe and method of manufacture and has for one of its principal objects the production of a shoe or the like in a relatively simple manner, with a minimum of labor and without the use of expensive or complicated machinery.

One of the important objects of this invention is to produce a shoe which is simply and easily built but which, at the same time, will be sturdy and long lasting.

Another and further important object of the invention is to provide a shoe constructed by a simple method and composed of a minimum number of parts stitched or otherwise fastened together in such manner that the wearing qualities of the shoe itself will be considerably enhanced.

Other and further important objects of the invention -will be apparent from the exposures in the accompanying drawing and following specification.

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a side elevation of the improved shoe of this invention showing a particular type of shoe but it will be obvious that various other types of shoes can be constructed by the method of this invention.

Figure 2 is a bottom plan view showing the first stage or step in the manufacture of the improved shoe of this invention.

Figure 3 is an enlarged sectional View taken on the line 3-3 of Figure 2 looking in the direction indicated by the arrows.

Figure 4 is a plan view showing the inner face of the outsole which is used in the construction of the improved shoe of this invention and illustrating more particularly the method of mounting the shank tuck upon the inner face of the outsole preparatory to assembling the out-sole and shank tuck with the previously assembled insole and upper illustrated in Figure 2.

Figure 5 is a sectional view taken on the line 5--5 of Figure 4, looking in the direction indicated by the arrows.

Figure 6 shows a modification of the invention embodying a diierent shoe which includes a toe portion and a slightly different mode of construction.

Figure '7 is a longitudinal sectional view taken on the line 'I--1 of Figure 4.

Figure 8 is a section of one edge of the shoe taken on the line 8-8 of Figure 1.

Figure 9 is a section of one edge of the completed shoe taken substantially on the line 9--9 of Figure 4, but including the assemblage of all the essential parts of the shoe.

As shown in :the drawings:

The reference numeral I0 indicates generally the upper of the improved shoe of this invention which is shown as being of the toeless type, but the invention method may be used to produce shoes of almost any type, within limits.

The shoe is shown as having what is known as a mud-guard which is illustrated at I2, but this mud-guard may be dispensed with if desired. The out-sole of the shoe is indicated at I4 and the insole at I6. This insole is sometimes called the sock lining.

The first step in the manufacture of the improved shoe of this invention consists in sewing or stitching the mud-guard I2 to the upper IU, this connecting line of stitching being obviously around those edges pf the upper which are eventually fastened to the corresponding edges of the out-sole. Obviously, When the mud-guard is not employed this step is omitted.

The sock lining or insole I6 is then attached to the upper Ill by line of stitching I8 as best shown in Figures 2 and 3. The corresponding adjacent edges of the upper I0 and the insole I6 are aligned as shown in Figure 3 previous to the stitching operation. The stitches which connect the mud-guard I2 to the upper I0 are indica-ted at 20 in Figures 3 and 9.

The cuit-sole I4 then has the shank tuck 22 applied to its inner face in the manner illustrated in Figure 4. As shown in this figure, the shank tuck 22 has its forward edge widened to correspond to the width of the adjacent portion of the out-sole I4. Two lines of

stitching

24 and 26 are then employed to fasten the forward edge of the shank tuck to the out-sole and a series of nails or the like 28 serve to attach the rear end of the shank tuck :to the corresponding heel portion of the out-sole. The shank tuck ordinarily includes a steel reinforcing strip as shown at 30.

The two portions of the shoe, namely, the assembled upper and insole and the assembled shank tuck and out-sole are then brought together preferably upon a last as indicated at 32 in Figure 6 after which the mud-guard or the outer edges of the assembled upper and insole are then cemented to the corresponding edges of the out-sole after which the parts are then stitched together by final line of stitching as indicated at 34 in Figure 9 and also in Figure 8.

The shoe illustrated in Figure 6 has no mudguard but the upper 40 is simply flared out at the edges as shown at 42 and after being preliminarily united to the insole which is not shown in this case, the preliminarily joined elements `are then assembled with the out-sole 44 in the same manner as previously described.

It will be seen that herein is provided a novel yet Well built shoe which is simple of construction and readily manufactured with a minimum of labor and without any diflicult assembling opera tions, not to mention the fact that no cumbersome or expensive machinery is required for production.

The shank tuck 22 may alternatively be cemented or otherwise fastened to the insole i6 instead of to the out-sole I4 and this ,operation will then comprise a, part of the first or preliminary step in the assembly of the improved shoe of this invention. Also, the shank tuck, when it is fastened `to the out-sole I4 can be glued thereto and the lines of

stitching

24 and 26 shown in Figure 4, be `accordingly dispensed With.

I am aware that many changes may be made and numerous details of construction Varied throughout a Wide range Without departing from the principles of this invention and I therefore, fdo not purpose limiting myself in the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention:

A method of manufacturing shoes comprising preliminarily fastening a mud-guard to the shoe upper with the edges of the mud-guard projecting beyond the edges of the upper, then stitching an insole to the combined mud-guard and upper With the edges of the insole and the edges of the upper in alignment, assembling a shank tuck to an outsole and then applying the assembled shank tuck `and out-sole to the mud-guard, While all the parts are positioned upon a last, the edges of the mudguard and `out-sole being in alignment.
