Application January 14,

4 Claims.

This invention relates to boots and shoes and particularly to means whereby the upper is con nected to the sole.

Heretofore uppers have been connected to the 5 soles of shoes by slitting the edge of the sole inward and then inserting the margin of the upper within this slit or channel, as it is quite usually termed. These slits in soles have been heretofore made by means of a fixed knife against which the sole is drawn, this knife not cutting away any material but simply slitting or parting the material of the sole. By reason of the fact that the knife used must be smooth on both faces, the walls of the slitor channel are relatively smooth 5 and not roughened and because no material is taken out where the slit is formed, the insertion of the upper acts to spread the two walls of the slit so that the margin, of the sole is thicker than the body of the sole inward of the margin. This requires that the sole be evened or leveled under very heavy pressure in order to attempt to render the entire sole of an even thickness and prevent any protuberance or ridge being formed which would be uncomfortable to the wearer. Inthis form of connection between the sole and the upper, the margin of the upper is inserted in said slit and in many cases cemented therein by Dyroxylin cement. The outside finished surface of the upper thus confronts the relatively smooth opposed surfaces of the cut or slit, and'this requires that these smooth and finished surfaces of the upper shall be cut away to permit the cement to hold.

This roughing or cutting away of the upper ;5 very gradually reduces its strength. Furthermore a slit will only permit one thickness of the upper to be inserted within the slit or cut and as a consequence the stitching, if stitching is used, will pass through the upper very close tothe in- L0 ner edge thereof, thus rendering the upper liable to tear out at this point.

The general object of this present invention is to provide a novel and improved mode of conheating the upper tothe sole of a shoe which will L5 do away with the objections above stated, which will permit of a more expeditious handling of the material, and an easier formation of the shoe,

which is applicable to shoes where the upper is cemented, stitched, pegged or stapled, which is i0 applicable to turned shoes, and applicable to shoes having either a single or a double sole, and with or without a welt.

A further object is to provide a shoe construction whiclnwill be particularly comfortable, flexi5 ible and durable and which will eliminate ridges,

, sole 10 and a portion of the upper 11.

ness throughout its area, after the upper is applied and eliminating the necessity of placing the sole under great pressure to level the sole, which pressure tends to crush and weaken the fibre of the sole.

A further and important object is to so construct the joint between the sole and upper that the flesh side of the upper may be brought in contact with the walls of the groove, which, as

before stated, are roughened, so that the upper can be cemented to the sole, as by pyroxylin cement without the necessity of roughing up and thereby weakening the material of the upper.

Still another object is to so construct the shoe that a' welt may be attached to the upper and inserted into the groove and shoe and the welt and upper stitched or otherwise attached to and through the sole.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein:--

Figure 1 is a fragmentary vertical section through the upper and sole of a cemented shoe;

Figure 2 is a like view to Figure 1 but showing a double sole shoe;

Figure 3 is a like view to Figures 1 and 2 but showing the upper sewed to the sole;

Figure 4 is a like view to Figure 1 but showing a welt attached to the upper and sole without an inseam;

Figure 5 is alike view to Figure 4 but showing a double sole shoe with a welt, but no inseam;

Figure 6 is a like view to Figure 5 but showing a turned shoe with a concealed stitch, and a surplus of upper material inside the shoe.

1 In Figure 1, I have illustrated a portion of a The-sole is formed entirely around its periphery with a groove 12. This groove may be placed medially between the upper and lower surfaces of the sole or may be placed closer to the upper surface than to the lower surface and may have any desired depth. This groove is formed by means of the grooving machine which forms the subesa-ton tom of the groove through the fibres of the sole to the surface of the flesh side of the sole, the

stitching extending inward from the shoulder or bottom of the groove, this stitching being designated 150. After this stitching has been done,

the upper, lining and doubler are trimmed or out 01f even with the margin of the sole, then this margin is laid or leveled to its original position, binding the two-ply fold of the upper in the groove 12. Then the sole is turned right side out, the shank piece is placed, the shoe is second lasted, heel seat lasted, leveled, beaten up and slicked up for the heeler, etc.

It will be seen that the novelty in my shoe construction is based primarily upon sawing out a groove of uniform thickness in the sole, this groove extending inward to any desired depth and distinguished from merely cutting a slit or channel in the sole by means of a. knife, the saw out making a kerf or groove, the inner surfaces of the walls of which are "roughed by the teeth of the saw instead of being smooth and the inner end or wall of the kerf or groove being formed by a shoulder or wall of appreciable thickness against which the bight of the fold at the margin of the upper is solidly abutted.

It is also stressed that by making this groove or kerf in the manner above stated, the flesh or rough face of the upper leather is broughtinto contact with the rough surface of the opposed groove walls, and thus may be readily cemented thereto without the necessity of roughing the grain surface of the upper leather and thus weakening it.

Furthermore, not only does this construction permit the passage of the stitches, pegs, or staples through twothicknesses of upper at some distance from the inner edge or bight and thus prevent these stitches from being torn out, but these two thicknesses occupy exactly the same space as the leather removed from the sole by the saw cut so that there is no humping up of the leather at the margin of the sole, due to one thickness of the upper being disposed in this cut, but the upper and lower surfaces of the sole at the margin are even, and level with the upper and lower surfaces of the sole at the middle of the sole, thus doing;

away with the necessity of compressing the margin of the sole under heavy pressure and thus crushing the leather and decreasing its strength.

It is obvious that the groove 12 may be .of any desired width and of any desired depth and may be positioned at any desire distance from the upper or lower'faces oi the sole or the upper and lower faces of an inner sole in case there is an inner and outer sole and further that this groove may be extended into the sole at any desired angle to the upper and lower faces of the sole instead of being parallel thereto.

It will be seen that with the construction shown in Figure 6, the stitching is on the inner face of the sole and with this method of grooving the sole, the stitch embeds itself into the flesh side of the sole, leaving a smooth surface with the outer portion of the stitch concealed by the upper which is within the groove. It is particularly important that in this construction, the stitch extends between the shoulder or bottom of the groove through the heart or firm portion of the sole to the inner or flesh side sothat these stitches are taken through the strongest part of the sole and extend through the upper at a distance from the edge of the upper so that there is no danger of tearing out.
