7 Claims. (Cl. 36-17) This invention relates to shoes, and more: particularly to an improved shoe construction which can be made by the slip-lasted method.

One of the objects of the invention is to produce an improved shoe which will be light in weight, flexible on the foot of the wearer, neat iii-appearance and economical to manufacture.

Another object is to so construct a shoe that it can be made by the slip-lasted method and have its sole attached by the conventional Goodyear stitching method.

A further object is to produce a welt type of shoe by an improved method of construction.

Other objects. of the invention will become apparent from the following description taken in connection with the accompanying drawing showing a shoe and the method by which it is constructed.

In the drawing:

Fig. 1 is a top view of the sock lining employed in making the shoe;

Fig. 2 is a view showing how the upper, the sock lining and the welting are secured together:

Fig. 3 is a bottom view showing how the" bottom filler is embodied in the shoe. together with the heelreenforcement and the shank piece;

Fig. 4 is another bottom view similar to Fig. 3, but showing the marginal portion of the sock lining cemented over the filler;

Fig. 5 is a perspective view of the completed shoe, and r Fig. 6 is an enlarged sectional view showing details, said view being taken on the line 6-6 of Fig. 5.

Referring to the drawing in detail, and first to Fig. I, there is shown a sock lining piece I which is died out from a suitable piece of fabric which may be reenforcedby a backing sheet if such is desired. This sock lining is of larger size than the size of the shoe of which it is to form a part. The top surface 01 the sock lining is shown in the figure, and upon this surface is placed a guide line shown by the dashed line 2. The sock lining is also provided with two cuts 3, which will be at the forward part of the heel section of the sock lining, that is at a line which will be at the breast line of the heel of the shoe when the shoe is completed.

As shown in Fig. 2, the upper I of the shoe. which is made from suitable died out pieces of material sewed together, has its lower marginal portion adjacent its lowered e 5 stitched to the sock lining at the guide line 2 by means of stitching 6. The size of the upper together with the guide line at which the upper is stitched to the sole l3 stitched thereto.

sock lining will determine the sizeof the shoe; After the upper is stitched'to the sock lining, awelting 'l'is next sewed by stitches 8 to both the upper and the sock lining, this stitching being slightly 'above the stitching B employed to secure the upper to the sock lining. The welting is of fairly narrow width, and the stitching 8 is adjacent to the edgewhich is arranged to be substantially flush with the lower edge 5 of the upper.

After the sock lining and the upper, plus the welting, have been stitched together, the shoe is slipped over a last 9, shown in Figs. 3 and 4. The bottom surface of the sock lining has now applied thereto, by a suitable cement, a filler member II]. This filler is of a size to be within and have its edge spaced slightly from the stitching Band 8 employed in sewing the upper and the welting to the sock lining. The filler may be of any suitable material such as a fibre material or a yieldablematerial, as, for example, a composi tion of cork, if it is: desired to produce a cushion sole type of shoe. On the bottom side of the filler there is provided a heel reenforcement piece H and a shank piece I 2. With the bottom of the shoe now in the condition as shown in Fig. 3, the marginal portion of the sock lining and the bottom surface of the filler have adhesive applied thereto, and then. the marginal portion of the sock lining is pulled over the edge of the filler and secured to the bottom surface thereof. Due to the fact that the filler is of such a. size that its peripheral edge adjacent the sock lining is spaced slightly inwardly of the stitches 6 and 8, the lower marginal portion of the upper and the welting will be turned inwardly at the time the sock lining is pulled over the filler in a manner such that the. welting will extend outwardly from the edge of the filler, thus presenting the relationship shown in Figs. 4 and 6. When the welting is in this position, it is ready to have the out- The cuts 3 in the sock lining insure that there will be no puckering or unevenness of the sock lining at the juncture of the heel portion with the forward portion to which the upper and welting have been stitched.

The laying of the outsole I3 is performed by the conventional method of Goodyear outsole laying. which may embody the use of suitable cement for securing the outsole to the bottom surface of the filler and the exposed marginal portion of the sock lining, and also the bottom surface of the welting. The outsole is then stitched to the welting by a Goodyear lock stitch which extends into the outsole as far as the channel which is cut around the edge of the outthe open toeand open, heel styl but it is to be understood that other styles of shoes can be made by the method of construction shown and described. The improved shoe construction results in a shoe which is very light weight and extremely flexible on the foot of the wearer. The shoe can be economically manufactured, since, all of the. parts are sewed together, which operation does By sewing not require highly skilled workers.

the upper to the sock lining at a predetermined I line, and also sewing the welting to the upper and the sock lining, the shoe can be constructed as to size without the necessity of lasting the upper to an insole, as iscommon practice.

What is claimed is:-

1. In a shoe constructionya sock lining, an upper having its lower'marginal portion secured in overlying relation to the sock lining at a substantial distance from the edge ofthe sock lining, a welting secured in overlying relation to the upper adjacent its lower edge and extending outwardly, the sock lining marginal portion ex-' tending beyond the welting, a filler positioned 'on the bottom of the sock lining and of a size to lie within the outline defined by the welting and the secured marginal portion of theupper, the marginal portion of the-sock'lining beyond the lower edge of the upper beingturned 'over' and secured to the bottom'surface of the filler, and an outsole stitched to the outwardly extending portion of the welting, and overlying the marginalportion of the sock lining.

2. In a shoe construction, a filler member, a sock lining piece overlying the filler member and having its marginal portion turned over the edge of the filler member and secured to the-bottom surface of said member, an upper having its marginal edge stitched to the sock lining at thepart' thereof which is turned over the edge of the filler member, a welting positioned in overlying relation to' the upper closely adjacent its stitched marginal edge and being stitched to the upper, and an outsole stitched to the welting outwardly of its stitching employed'in securing the welting to the upper.

3. In 'a method of making a shoe which comprises stitching the lower marginal edge portion of an upper and a welting to a sheet of material shaped in the general form'of'the bottom of a shoe but of a size greater than the size of the shoe to be made in order to provide a marginal portion extending beyond the upper and welting,
