VILFRED J. DREY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO THOMAS BEATTY, OF SAME PLACE.

SHOE.

SPECIFICATION forming part of Letters Patent No. 496,822, dated May 2, 1893.

Application led .T anuary 30, 1892. Serial No. 419,812. (No model.)

To all whom t may concern,.-

Beit known that I, WILFRED J. DREY, acitizen of the United States, residing at Philadelphia,in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shoe-Making, of which the following is a specification.

My invention has relation to shoes, particularly those the soles of which contain an inner lo layer of cork and which are known tothe trade as cork sole shoes, and has for its object the' provision of certain improvements in the manufacture of such shoes, to the end that their cost may belessened and the soles therex 5 of rendered more durable, flexible and waterproof. In shoes of the character mentioned, it is necessary to sew a strip of leather, called the casing, to the inner sole, the same following the contour of such sole enlarged and zo forming a recess between it and the outer sole, in which recess is placed a thin layer of cork. Heretofore, this casing has been composed of a simple, narrow strip of leather of such Width as to prevent more than one line 2 5 of stitching passing therethrough without being run into by another such line. Consequently, it has been found necessary to place a second leatherinner sole, in the recess aforementioned, for securing thereto the welt. 3o Thus the sole of the shoe is rendered Very stiff and heavy and its cost increased and the thin layer of cork therein does not perfectly exclude moisture, while, owing to the practical independence between the first inner sole and casing, and the second inner and the outer soles, the durability of the shoe is impaired.

My invention consists in the provision of a casing, for the purpose specied, of a charac- 4o ter more particularly described hereinafter, the same being adapted for reception of two separate lines of stitching, one line passing through said casing, the casing-cover, the upper and the inner sole, and the other line through the welt, said casing, casing-cover, upper and inner sole. Thus. there is secured a perfect unity between the inner and outer soles and a corresponding degree of durability, dispensing entirely with the secondleather 5o inner sole aforementioned and rendering the sole of the shoe considerably lighter and cheaper and increasing its flexibility.

Referring to the Aaccompanying drawings: Figure l is a perspective View of a portion of the strip of which the improved casing is coin- .55.' posed. Fig. 2 is a plan view, partly broken away, of the insole. Fig. 3 is a similar view, showing the relative positions and the means of securing in place the various parts of the improved sole. Fig. 4 is a vertical section of 6c a portion of the complete sole; and Fig. 5 is an end view of the casingv in position to receive the first line of stitching.

In' said drawings, A represents the leather inner sole, the same being .channeled at a and having its edge split, as shown at a. B is the layer of cork, O the outer sole, and D the casing, said casing being formed of a strip of leather provided with a longitudinal groove d and having one of its edges split, as at d. E 7o represents the welt and F the upper.

As illustrated in Figs. 3 and 4., the side a2 of the split portion a', of inner sole A, when the latter is in its normal position, is bent upwardly, leaving a recess d3 in the edge of said 75 sole. In this recess are first laid the lower edges of the upper F, then the casing-cover d2 is laid upon the latter, upon which cover is placed, in the condition shown most clearly Y in Fig. 5, the casing D, whereupon the stitch- 8o ing g is run in the groove d, through the casing-cover, the upper, inner soleAand into the channel c therein. Thus said casing, cover and upper are secured firmly to the inner sole of the shoe. This having been accomplished, the portion d3, of the edge d4 of the casing, is trimmed off on dotted linea: of Fig.

5. Then the portion d5 of said edge, on dotted line 'y of said figure, and the side d6 of the split in said casing, are removed, resultingin 9o the formation of a recess or seat e for the Welt E. The casing-cover d2 is now turned up over the casing D, as shown at d7 in Fig. 3, and

the welt E placed thereon, and then the stitching 7i is runV through said welt, cover, casing, 95 upper and the upturned portion a2 -of the inner sole A, as shown in the drawings, securing each of these parts to said inner sole. In this position of the various parts there is left a recess b, the edges of the Welt, casing, cover, roo

- upper and part A2 being trimmed off, as shown in said Fig. 3, and forming the walls of the recess b, said inner sole forming the bottom of this latter recess. In this recess is secured, by cementing to the inner sole A, the cork sole B, to Whichlatter is cemented the outer sole c and the same sewed, by the stitching c, to the welt E, When the operation is complete.

By the improved method of manufacture hereinbefore described the dispensing with the second inner sole of leather effects a saving of materialand, consequently, of expense, a lessening of the Weight of the completed sole and permits of the use of a layer of cork equal in thickness to that of such second inl ner sole and the layer of cork heretofore used,

Furthermore, as is quite obvious, such sewing may be done by hand.

What I claim as my invention is as follows:

In a cork-sole shoe, the combination of the inner sole, the upper, the Welt, the outer sole, the cork-sole casing, a layer of cork between said soles, said inner sole having its edge split, being channeled and having one side of the split edge upturned, and said casing having one of its edges split and provided With a 1ongitudinal groove, a line of stitching in the latterv and passing through the casing, upper, inner sole and into said channel and one side of the split edge of the casing being removed, forming a seat for the Welt and affording room for another line of stitching which passes through said Welt, casing, upper and upturned portion of the inner sole, said stitching serving to unite the aforementioned parts in the completed shoe,substantially as shown and described.

In testimony whereof I have hereunto set my hand this 23d day of January, A. D. 1892. VVILFRED J. DREY.
