B designates a shoe-construction of the glued or Compo type, which includes the usual upper i, for which is provided a one-piece sole 24 of suitable material and preferably contoured to the desired outline in the usual manner. In

its rear portion the sole 24 is split completely across its width and thereby provided with an inner tongue 25 on its flesh side 26 and an outer tongue 21 on its grain side 28, each tongue 25, 21 preferably extending from the break 29 of the shoe rearwardly to the heel thereof.

The rear margins of the tongues 25, 21, from the break 253 to the heel of the shoe are suitably skived and beveled, as at 30, 3I, respectively, the bevel 39 of the inner tongue 25 overlapping the bevel 35 of the outer tongue 21, the latter being also suitably finished for providing a heel-seat 32. The concealed face of the inner tongue 25 is provided with a longitudinal groove or channel 33 extending from the break 29 approximately to the heel-seat 32 for reception of a shank-stiffener 34, as best seen in Figures 3 and 4.

The fore part of the sole 24, from the break 29 to the toe of the shoe, is slit inwardly and thereby provided with a channel 35,, which extends around the lateral side of peripheral face of the sole 24, and which is disposed approximately equally intermediate of the flesh side 26 and grain side 28 thereof.

The channel 35 spits the marginal portions of the sole 24 into an upper or inner flap 36 and an opposing lower or outer flap 31, each coextensive with the channel 35, which latter is of suflicient depth to admit the marginal portions of the upper I as will presently appear, in such manner as to leave the central portion of the sole 24, under the ball of the foot, intact, integral, and of a single thickness.

The sole 24 being provided as described, the

stiffener 34 is by suitable nails 38 attached tothe' inner tongue 25, so as to be in registration with the groove 33 in the outer tongue 21. The sole 24 is then suitably mounted on the last (not shown), and the tongues 25, 21, are securely glued or cemented together, whereby the integrity of the sole 24 is substantially restored, and the stiffener 34 is snugly enclosed in its proper position between the tongues 25, 21, thus obviating the need of a stifiener-cover, as employed in the shoe A hereinbefore described.

The upper l is then arranged about or built upon the last, and the portion of the upper I from the break 29 to the heel of the shoe is glued and then stretched or pulled to and over preferably merely the bevel 30 of the tongue 25, suitable fastening elements 38, as lasting nails or staples, being driven through the margin 39 of the upper I, and clinched in the inner tongue 25 for retaining the upper I in position during the hardening or setting of the glue or cement by which the upper I is attached to the sole 24 in the customary manner.

The margin 48 of the portion of the upper I' from the break 29 to the toe of the shoe is suitably beveled or skived and likewise glued, and the upper I is then stretched over the last with the margin 49 neatly inserted in the channel 35 of the sole 24, the parts being retained in such position by any suitable means, not shown, during the hardening or setting of the adhesive for attaching the margin 40 to the lower wall, or if desired, to both walls of the slit or channel 35, and the sole 24 to the upper l.

The heel M is then attached to the heel-seat 32, and the manufacture of the shoe 3 is thereafter completed in the manner well known to those skilled inthe art.

It will be seen that, in the glued-shoe B, all stitching is omitted, and reliance is had on the cement alone for securing and maintaining the upper in the interior of the sole between the flapportions 25 and 21 and. also for securing said flap-portions in place.

It will be understood that other changes and modifications in the form, construction, arrangement and combination of the several parts of my new shoe constructions and in the methods of manufacturing the same may be made and substituted for those herein shown and described without departing from the nature and principles of my invention.

Having thus described my invention, what claim and desire to secure bygLetters-Patent is,-

1. A shoe comprising, in combination, a sole having a slit extending inwardly from its peripheral face intermediate its inner and outer sides, said slit dividing the marginal portion of the sole into upper and lower flaps, an upper having its margin beveled and foldably disposed in said slit,

and means'including a and within the folded margin of the upper for securing the upper to the lower sole-flap, the welt having a beveled face for engaging the beveled face of the margin of the upper.

2. A shoe comprising, in combination, a sole having a slit extending inwardly from its periphwelt disposed in theslit' eral face intermediate its inner and outer sides,

said-slit dividing the marginal portion of the sole into upper and lower flaps, an upper having its margin beveled and foldably disposed in.

said slit, and means including a welt disposed in the slit and within the folded margin of the upper for securing the upper to the lower soleflap, the welt having a beveled face for engaging engaging the lower sole-flap.

3. The method of making a shoe which consists in inwardly forming a slit in the peripheral the beveled face of the upper-'margin and a lip for face of an outsole and thereby dividing the margin of the sole into opposing inner and outer flaps, lasting the shoe, folding inwardly the marginal portion of the shoe upper between the upper and lower flaps, beveling the free margin of the upper, disposing a wedge-shaped welt within the folded upper-margin for overlying the beveled portion thereof, and then stitching together the welt, the upper, and the outer flap of the sole.

4. The method of making a shoe which consists in forming a heel-seat on an outsole, inwardly forming a slit in the peripheral face of the outsole from the heel-seat to the toe of the shoe and thereby dividing such marginal portion of the sole to include opposing upper and lower flaps, forming a groove in the inner face of the outsole from the heel-seat to the brake of the shoe, mounting a shank-stiffener in said groove, concealing the shank with a cover extending from the break of the shoe to and over the heel-seat, lasting the shoe, disposing the marginal portion of the upper in said slit, nailing the rear-part of I the upper, the sole, and the cover together at the heel-seat of the shoe, and then stitching the margin of the upper tothe lower flap of the sole,
