- Important objects of the present invention are, herefore, to reinforce the marginal portions of shoe-upper and to eliminate or at least to re- ⁇ uce to a minimum the upper roughening operalon.
- a multi-ply upper (this porion being )mmonly referred to as the "lasting allowance) fuller than normal by a width substantially equal to the Width of the normal lasting allowance of the upper and turning the excess material back in the usual manner to form the complete upper.
- the portions of the lasting allowance which are 15 cut fuller than normal preferably should extend from about the tip line to the heel breast line at each side of the shoe. As illustrated, these porper roughening operation will have to be performed along those portions of the lasting margin of the upper which have been reinforced in the manner described, in order to insure that a reliable cement bond will be obtained betvveen35 the overlasted marginal portions of the upper and the outsole.
- the excess material preferably extends from about the tip line to the heel breast line of the shoe and is of a width substantially equal to the width of the normal lasting allowance of the upper, so that when the material is turned back upon the outer leather layer of the upper its lower edge will coincide substantially with the bottom edge of the normal lasting allowance of the upper.
- the lining of the upper, or a portion of the lining is composed of leather, for example if the quarter lining is of sheepskin, as is not infrequently the case, the surface exposed, if the lining is turned back to reinforce the lasting margin of the upper, will be the grain surface of the leather. This grain surface should be roughened lightly to remove the finish from the leather and thus to prepare it to receive the sole attaching cement.
- the method of preparing a multi-ply upper disclosed by the present invention not only reinforces and strengthens the lasting allowance of the upper at each side of the shoe from about the tip line to the heel breast line, but it also reduces materially the area which needs to be roughened since it provides exposed surfaces at these reinforced portions of the upper which in their normal condition and without roughening are well adapted to receive the pyroxylin cement by which the sole is to be attached to the shoe. Consequently, the upper roughening operation and the numerous disadvantages resulting therefrom are in this way reduced to a minimum.
- Fig. 1 is a view in side elevation of a multi-ply shoe upper with the marginal portion of its lining cut fuller than normal, turned back upon the outer layer of the upper, and secured thereto partway of its length by rows of stitching, the lining being formed partly of fabric material and partly of leather;

- Fig. 4 is a transverse sectional view of a portion of the shoe shown in Fig. 2 after the outsole has been applied;
- Fig. 5 is a transverse sectional view of a portion of a shoe in which the doubler of the multiply upper has been cut fuller than normal as in Fig. 3, the upper shown in Fig. 5 having been side lasted by cement instead of by staples;
- Fig. 6 is a View in side elevation of a multi-ply upper with the marginal portion of the outer leather layer cut fuller than normal', turned back upon said outer layer, and secured thereto part- Way of its length by a row of stitching;

- Fig. 8 is a transverse sectional view of a portion of the shoe shown in Fig. 7 r rter the outsole entirely from one material such as fabric, for example, canvas or duck, or it may, especially in higher grades of shoes, be made of two different materials.
- the upper may have a forepart or vamp lining made of cotton fabric and a quarter lining made of leather, such as sheepskin.
- the present invention contemplates the use of either type of lining since the steps of the method herein disclosed may be performed with substantially equal facility whether the lining is all fabric or is formed partly of fabric and partly of leather.
- the lining I6 (Fig. 1) is cut substantially fuller than a normal lining at certain portions of its margin, the purpose of which will be hereinafter explained.
- the lasting marginal portion of the upper that is, the portion to which the outsole is secured in the manufacture of shoes which have the outsoles attached by means of cement, is commonly referred to as the lasting allowance of the upper, since it forms the portion which secures the upper in lasted relation to the insole after the lasting o-peration, this lastingallowance ordinarily being about one-half or five-eighths of an inch in width.
- FIG. l shows the three-ply upper I0 having a vamp lining formed of fabric material I1 and a quarter lining formed of leather I9, such as sheepskin, and illustrates how the fabric and leather lining I6, cut in the manner described, extends beyond the lasting margin of the doubler I4 and the leather outer layer I2 of the upper after the parts have been secured together by stitching, the leather outer layer I2 and the doubler I4 having been cut in accordance with the usual upper pattern so that they are normal in size and shape.
- leather I9 such as sheepskin
- the portions of the lining I6 which have been cut fuller than normal and which, as stated, extend beyond the normal portions on either side of the upper from about the' tip line to the heel breast line of the shoe, are turned over upon the grain surface of the lasting allowance of the outer leather layer I2 of the upper and are secured thereto by means of a plurality of rows of stitching I8 and 20, these rows, as indicated in Fig. l, extending substantially parallel to the margin of the upper and preferably being located approximately onequarter inch apart.
- FIG. 1 shows the stitching variations in the extending only part way along the turned-over portion of the lining I6 in order to illustrate how the upper appears both before and after the excess material of the lining is stitched to the outer surface of the upper.
- the lower row of stitching 20 is located fairly close to the edge of the turned-back material of the lining so that this material will be held closely against the leather outer layer I2 of the upper at the lower edge of the lasting margin. This insures that after the shoe is lasted the outer edges of the overlasted margin ofthe upper will afford a substantially solid foundation to which an outsole may be permanently secured by cement without danger of the turned-back portions of the upper pulling away or becoming loose along the edges of the outsole.
- the lasting allowance or margin of the shoe upper will thus be reinforced and strengthened by the turnedback lining so that the danger of tearing the upper during subsequent operations on the shoe will be practically eliminated.
- the upper I0 and an insole 22 are now assembled on a last 24 and the shoe is pulled over and lasted in any usual or suitable manner.
- the upper is secured in lasted relation to the insole at the sides of the shoe by means of staples indicated at 26 which, as shown in Fig. 4, are anchored in the substance of the insole without passing completely therethrough.
- the shoe may conveniently be side lasted in this fashion with the aid of kthe staple side lasting machine shown in Letters Patent of the United States No. 1,815,297, granted July 21, 1931, on an application filed in the name of George Goddu.
- the toe end of the shoe may be cement lasted, for example, in a bed lasting machine with the aid of the toe plate or binder disclosed in United States Letters Patent No.
- the heel end of the shoe may be secured in lasted relation by driven fastenings 28. It should be understood, however, that the lasting of the upper may be done in other ways and by hand, or with the aid of other machines.
- the shoe may, if desired, be side lasted with cement as shown in Fig. 5, in which case no staples will extend through the margin of the upper in the manner illustrated in Fig. 4.
- the edges of the turned-back portions of the lining I6 adjacent to the stitching 20 in order to insure that the outer edge of the lasting margin will be substantially flush with the edge of the shoe bottom and thus prevent the turned-back portions of the lining from extending out of the crease between the upper and outsole in the nished shoe. Since the-se turned-back portions of the lining are substantially equal in width to the width of the normal lasting allowance of the upper, it will be seen that, except where there have been unusual stretch of the upper mater'als during the lasting operations, the outer edges of the turned-back material will be located fairly close to the edge of the shoe bottom and, consequently, will require very little trimming.
- the row of stitching 20 is located adjacent to the lower edge of the lasting margin of the upper so that, after the trimm'ng operation has been performed, the excess material of the lining will be held closely united to the outer surface of the upper along the edge of the shoe bottom.
- a firm marginal surface is provided along both sides of the shoe bottom, from about the tip line to the heel breast line, this surface being especially effective in obtaining a solid and permanent attachment of the sole to the shoe.
- the bottom filler indicated at 30, is applied in the usual way to the shoe bottom and a shank piece 32 is secured in proper position at the shank portion of the shoe.
- Fig. 2 shows the shoe after the surplus lining material has been trimmed off and the bottom filler 30 has been applied to ll the space between the inner edges of the overlasted portions of the upper at the forepart of the shoe, and illustrates/how the shoe bottom will appear at this stage of the process. It may be well to point out here that it is within the scope of the present invention to reinforce the lasting margin of the multi-ply upper by utilizing any one of the layers of material of which it is made up.
- the doubler instead of the lining may, if desired, be cut fuller than the normal lasting margin of the upper, turned back upon the outer layer of the upper, and secured thereto by a plurality of rows of stitching.
- Fig. 3 shows a shoe on a last 24 at the same stage of completion as the shoe illustrated in Fig. 2, with the doubler I4 instead of the lining cut wider than normal from about the tip line to the heel breast line of the shoe and then secured by stitching I8 and 20 to the outer leather layer I2 of the upper to reinforce the lasting margin thereof.
- the next step in the method herein disclosed is to insure that all portions of the surface of the overlasted marginal portion of the upper, from the heel breast line to the tip of the toe, are in a to receive the sole attaching cement, so that when the cement is applied, it will become securely bonded thereto.
- the portions of the turnedback lining I 6 which are made up of fabric material I 'I extend at each side of the shoe from about the tip line to a point some distance rearwardly of the forward end of the shank portion of the shoe.
- the portions of the lasting margin of the upper which extend from this point to the heel breast line are reinforced by leather I9 which forms the quarter lining of the upper.
- the upper at the toe por tion of the shoe which, it will be remembered, was cement lasted with the aid of a toe plate, or binder and which will, therefore, be formed of the leather of the outer layer I2 with the grain side uppermost, should also be roughened lightly, as indicated at 3
- a coating of pyroxylin cement is now applied to I6 or by the marginal portion of the shoe bottom and allowed vto dry.
- a sole 34 (Fig. 4) is prepared for cement attachment by reducing the thickness of its marginal portion, particularly at the shank, roughening this marginal portion, and then applying thereto a band of pyroxylin cement. After the cement has dried it is activated on either the sole or the shoe bottom, or on both, with a suitable solvent, for example, with a solvent such as that disclosed in United States Letters Patent No.
- Figs. 4 and 5 are fragmentary views illustrating how the shoe appears in cross section after the sole 34 has been attached, Fig. 4 illustrating a shoe in which the lining I6 hasbeen turned back to reinforce the lasting margin of the upper, and Fig. 5 illustrating a shoe in which the doubler I4 has been turned back to reinforce the upper.
- the upper indicated generally by the reference numeral I0 has been side lasted to the insole 22 by means of cement so that no staple appears as in Fig. 4.
- Figs. 6, 7 and 8 illustrate the method of reinforcing the upper by cutting the marginal portion of the leather outer layer of the upper fuller than a normal lasting margin and turning the excess material back upon this outer layer and securing it thereto by a plurality of rows of stitching.
- Fig. 6 y shows an outer leather layer 36 of a multi-ply upper 38 having a doubler 40 and a lining 42.
- the marginal portion of the outer leather layer 36 has been cut fuller than a normal upper by a width substantially equal to the width of the normal lasting allowance of the upper or, in other words, about 1/2 or 5/8 of an inch Wider than such allowance, this fuller portion extending, as in the case of the lining, from about the tip line to the heel breast line of the shoe.
- the upper 38 and an insole 48 are assembled on a last 50 and the shoe is pulled over and lasted in any usual manner.
- the shoe may be side lasted by staples pletely through the insole.
- the toe end of the shoe may be lasted by cement with the aid of a toe plate or binder as previously described and the heel end, as illustrated, may be secured in lasted relation by driven fastenings, indicated at 53.
- the bottom filler 54 and a shank piece 56 are then applied to the shoe bottom in the usual way as shown in Fig. 7.
- the reinforced lasting margin ⁇ of the multiply upper 33 now has the flesh side of the leather outer layer 36 uppermost and therefore presents an unfinished and substantially rough surface from about the tip line to the heel breast line of the shoe, this surface being well adapted to receive the cement by which the sole is to be attached to the shoe.
- the overlasted marginal portion of the upper at the toe end of the shoe should be roughened lightly to remove the finish on the grain side of the leather, as shown at 55 (Fig. 7), and a coating of pyroxylin cement may then be applied to the overlasted marginal portion of the shoe.
- An outsole 58 (Fig. 8) is prepared for cement attachment, and, after the cement on the shoe bottom and/or on the margin of the sole has been activated, the shoe and sole are properly located relatively to each other and placed under pressure while the sole attaching cement is setting.
- the marginal portion of the upper is not only substantially reinforced at the sides of the shoe so that it will be better able to withstand excessive strains to which it may be subjected during the pulling over and lasting operations, but the upper roughening operation, which is usually necessary in the manufacture of shoes having the soles attached by cement in which the grain surface of the upper leather is to receive the sole attaching cement, is reduced to a minimum.
- That improvement in methods of manufacturing shoes which comprises cutting a shoe upper fuller than normal by a width substantially equal to the width of the normal lasting allowance of the upper, and turning the excess material back upon the lasting allowance and stitching it thereto before the upper is secured in lasted relation to an insole, thereby reinforcing the marginal portion of the shoe upper.
- That improvement in methods of manufacturing shoes which comprises cutting the outer layer of a multi-ply shoe upper with a normal lasting allowance, cutting a lining for the shoe upper fuller than normal by an amount about equal to the width of the lasting allowance of the upper, assembling the outer layer and lining and securing them together to form a completed shoe upper, and turning the excess material of the lining back upon the lasting allowance of the upper and securing it thereto, thereby reinforcing the marginal portion of the shoe upper.

- Ihat improvement in methods of manufacturing shoes which comprises cutting an outer layer for a shoe upper, a doubler, and a lining, the material of the doubler at the sides of the shoe being cut fuller than the outer layer and the lining, stitching the parts togetherto form a complete shoe upper, and turning the excess material of the doubler back upon the lasting margin of the outer layer of the upper and stitching it thereto, thereby reinforcing the marginal portion of the shoe upper.
- That improvement in methods c' manufacturing shoes which comprises cuttingmne of the layers of material of a multi-ply shoe upper fuller than normal, stitching the parts together to form a shoe upper, and turning back the excess material of the layer which has been cut fuller than normal against the outer surface of the lasting allowance of the outer layer of upper material and stitching it thereto before the upper is assembled with an insole on a last,- thereby to reinforce the marginal portion of the upper prior to the pulling-over and lasting operations on the shoe.

surface of the leather in such a manner that the finish is removed therefrom, thereby rendering this surface suitable to receive the sole attaching cement.
It will be seen from the above that in order to remove the finish from the grain surface of the leather, the lasting margin of the shoe upsubjected to a considerable amount of abrasion which may seriously weaken If the leather is thin or delicate 1t 1s not infrequently torn, even to such an extent that the upper 1s rendered Worthless and cannot be used, which, of course, greatly adds to the cost of manufacturing the shoes. Moreover, some kinds of leather, notably certain reptile skins, cannot be roughened effectively by the methods now in use since the horny nature of the scales or scutes on such skins prevents the rotating brush or abrasive Wheel from producing satisfactory results. In addition, considerable :lifliculty often arises in determining the por- `:ion of the margin of the upper which should be Toughened at the shank ofthe shoe, since the ocation of the edge of the insole cannot always )e determined accurately through the material )f the upper.
Important objects of the present invention are, herefore, to reinforce the marginal portions of shoe-upper and to eliminate or at least to re- `uce to a minimum the upper roughening operalon.
As illustrated herein, and in accordance with a eature of the invention, these objects are atiined by cutting the marginal portion of, for
sample, a multi-ply upper (this porion being )mmonly referred to as the "lasting allowance) fuller than normal by a width substantially equal to the Width of the normal lasting allowance of the upper and turning the excess material back in the usual manner to form the complete upper. The portions of the lasting allowance which are 15 cut fuller than normal preferably should extend from about the tip line to the heel breast line at each side of the shoe. As illustrated, these porper roughening operation will have to be performed along those portions of the lasting margin of the upper which have been reinforced in the manner described, in order to insure that a reliable cement bond will be obtained betvveen35 the overlasted marginal portions of the upper and the outsole.
It is within the scope of the present invention to reinforce a shoe upper by turning back the leather outer layer of the upper, the fabric or 40 fabric material of This unnished surface provides an excellent base upon which to the upper at each side of the shoe. If a fabric lining or a fabric doubler is used to reinforce the upper, the marginal portions of the lining or the doubler are cut fuller than normal in the manner described and the excess material is then 55 turned back upon the lasting allowance of the outer leather layer of the upper and stitched thereto. In either instance, the excess material preferably extends from about the tip line to the heel breast line of the shoe and is of a width substantially equal to the width of the normal lasting allowance of the upper, so that when the material is turned back upon the outer leather layer of the upper its lower edge will coincide substantially with the bottom edge of the normal lasting allowance of the upper. When the lining of the upper, or a portion of the lining, is composed of leather, for example if the quarter lining is of sheepskin, as is not infrequently the case, the surface exposed, if the lining is turned back to reinforce the lasting margin of the upper, will be the grain surface of the leather. This grain surface should be roughened lightly to remove the finish from the leather and thus to prepare it to receive the sole attaching cement.
The method of preparing a multi-ply upper disclosed by the present invention not only reinforces and strengthens the lasting allowance of the upper at each side of the shoe from about the tip line to the heel breast line, but it also reduces materially the area which needs to be roughened since it provides exposed surfaces at these reinforced portions of the upper which in their normal condition and without roughening are well adapted to receive the pyroxylin cement by which the sole is to be attached to the shoe. Consequently, the upper roughening operation and the numerous disadvantages resulting therefrom are in this way reduced to a minimum.
With the above and other objects in view the invention will now be described with reference to the accompanying drawings and pointed out in the appended claims.
In the drawings,
Fig. 1 is a view in side elevation of a multi-ply shoe upper with the marginal portion of its lining cut fuller than normal, turned back upon the outer layer of the upper, and secured thereto partway of its length by rows of stitching, the lining being formed partly of fabric material and partly of leather;
Fig. 2 is a perspective View of a shoe illustrating how the shoe bottom will appear after the upper shown in Fig. 1 has been lasted to the insole', trimmed, and the leather portions of the lasting margin roughened;
Fig. 3 is a perspective View of a shoe showing the shoe bottom at the same stage of completion as the shoe in Fig. 2, the doubler of the upper in v Fig. 3 having been cut fuller than normal and then turned back and secured to the leather outer layer of the upper;
Fig. 4 is a transverse sectional view of a portion of the shoe shown in Fig. 2 after the outsole has been applied;
Fig. 5 is a transverse sectional view of a portion of a shoe in which the doubler of the multiply upper has been cut fuller than normal as in Fig. 3, the upper shown in Fig. 5 having been side lasted by cement instead of by staples;
Fig. 6 is a View in side elevation of a multi-ply upper with the marginal portion of the outer leather layer cut fuller than normal', turned back upon said outer layer, and secured thereto part- Way of its length by a row of stitching;
Fig. 7 is a perspective View of a shoe showing how the shoe bottom will appear after the upper shown in Fig. 6 has been lasted to the insole; and
Fig. 8 is a transverse sectional view of a portion of the shoe shown in Fig. 7 r rter the outsole entirely from one material such as fabric, for example, canvas or duck, or it may, especially in higher grades of shoes, be made of two different materials. In the latter case, the upper may have a forepart or vamp lining made of cotton fabric and a quarter lining made of leather, such as sheepskin. The present invention contemplates the use of either type of lining since the steps of the method herein disclosed may be performed with substantially equal facility whether the lining is all fabric or is formed partly of fabric and partly of leather.
In cutting the different parts of the shoe upper in accordance with the method herein disclosed, the lining I6 (Fig. 1) is cut substantially fuller than a normal lining at certain portions of its margin, the purpose of which will be hereinafter explained. The lasting marginal portion of the upper, that is, the portion to which the outsole is secured in the manufacture of shoes which have the outsoles attached by means of cement, is commonly referred to as the lasting allowance of the upper, since it forms the portion which secures the upper in lasted relation to the insole after the lasting o-peration, this lastingallowance ordinarily being about one-half or five-eighths of an inch in width. The portions of the lasting allowance of the upper lining I6, therefore, which are out fuller than' a normal lining, extend at both sides of the upper from Vabout the tip line to the heel breast line of the shoe. These portions are cut fuller than a normal upper by a width substantially equal to the width of the lasting allowance of the upper, or about one-half or ve-eighths of an inch wider than a normal lining, and extend this distance beyond the marginal portions of the other layers of the multiply upper after the parts have been assembled and stitched together to form the completed upper. Fig. l shows the three-ply upper I0 having a vamp lining formed of fabric material I1 and a quarter lining formed of leather I9, such as sheepskin, and illustrates how the fabric and leather lining I6, cut in the manner described, extends beyond the lasting margin of the doubler I4 and the leather outer layer I2 of the upper after the parts have been secured together by stitching, the leather outer layer I2 and the doubler I4 having been cut in accordance with the usual upper pattern so that they are normal in size and shape.
After the materials have been cut and assembled to form the three-ply upper I0, the portions of the lining I6, which have been cut fuller than normal and which, as stated, extend beyond the normal portions on either side of the upper from about the' tip line to the heel breast line of the shoe, are turned over upon the grain surface of the lasting allowance of the outer leather layer I2 of the upper and are secured thereto by means of a plurality of rows of stitching I8 and 20, these rows, as indicated in Fig. l, extending substantially parallel to the margin of the upper and preferably being located approximately onequarter inch apart. Fig. 1 shows the stitching variations in the extending only part way along the turned-over portion of the lining I6 in order to illustrate how the upper appears both before and after the excess material of the lining is stitched to the outer surface of the upper. It will be vnoted in this figure that the lower row of stitching 20 is located fairly close to the edge of the turned-back material of the lining so that this material will be held closely against the leather outer layer I2 of the upper at the lower edge of the lasting margin. This insures that after the shoe is lasted the outer edges of the overlasted margin ofthe upper will afford a substantially solid foundation to which an outsole may be permanently secured by cement without danger of the turned-back portions of the upper pulling away or becoming loose along the edges of the outsole. The lasting allowance or margin of the shoe upper will thus be reinforced and strengthened by the turnedback lining so that the danger of tearing the upper during subsequent operations on the shoe will be practically eliminated.
The upper I0 and an insole 22 are now assembled on a last 24 and the shoe is pulled over and lasted in any usual or suitable manner. As illustrated in Fig. 2, the upper is secured in lasted relation to the insole at the sides of the shoe by means of staples indicated at 26 which, as shown in Fig. 4, are anchored in the substance of the insole without passing completely therethrough. The shoe may conveniently be side lasted in this fashion with the aid of kthe staple side lasting machine shown in Letters Patent of the United States No. 1,815,297, granted July 21, 1931, on an application filed in the name of George Goddu. The toe end of the shoe may be cement lasted, for example, in a bed lasting machine with the aid of the toe plate or binder disclosed in United States Letters Patent No. 1,894,678, granted January 17, 1933, upon an application led in the name of Joseph Fausse. The heel end of the shoe, as illustrated in Fig. 2, may be secured in lasted relation by driven fastenings 28. It should be understood, however, that the lasting of the upper may be done in other ways and by hand, or with the aid of other machines. lFor example, the shoe may, if desired, be side lasted with cement as shown in Fig. 5, in which case no staples will extend through the margin of the upper in the manner illustrated in Fig. 4.
After the lasting operations have been performed it is usually desirable to trim the edges of the turned-back portions of the lining I6 adjacent to the stitching 20, in order to insure that the outer edge of the lasting margin will be substantially flush with the edge of the shoe bottom and thus prevent the turned-back portions of the lining from extending out of the crease between the upper and outsole in the nished shoe. Since the-se turned-back portions of the lining are substantially equal in width to the width of the normal lasting allowance of the upper, it will be seen that, except where there have been unusual stretch of the upper mater'als during the lasting operations, the outer edges of the turned-back material will be located fairly close to the edge of the shoe bottom and, consequently, will require very little trimming. As stated, the row of stitching 20 is located adjacent to the lower edge of the lasting margin of the upper so that, after the trimm'ng operation has been performed, the excess material of the lining will be held closely united to the outer surface of the upper along the edge of the shoe bottom. In this way a firm marginal surface is provided along both sides of the shoe bottom, from about the tip line to the heel breast line, this surface being especially effective in obtaining a solid and permanent attachment of the sole to the shoe.
After the trimming operation has been performed, the bottom filler, indicated at 30, is applied in the usual way to the shoe bottom and a shank piece 32 is secured in proper position at the shank portion of the shoe. Fig. 2 shows the shoe after the surplus lining material has been trimmed off and the bottom filler 30 has been applied to ll the space between the inner edges of the overlasted portions of the upper at the forepart of the shoe, and illustrates/how the shoe bottom will appear at this stage of the process. It may be well to point out here that it is within the scope of the present invention to reinforce the lasting margin of the multi-ply upper by utilizing any one of the layers of material of which it is made up. Accordingly, the doubler instead of the lining may, if desired, be cut fuller than the normal lasting margin of the upper, turned back upon the outer layer of the upper, and secured thereto by a plurality of rows of stitching. Fig. 3 shows a shoe on a last 24 at the same stage of completion as the shoe illustrated in Fig. 2, with the doubler I4 instead of the lining cut wider than normal from about the tip line to the heel breast line of the shoe and then secured by stitching I8 and 20 to the outer leather layer I2 of the upper to reinforce the lasting margin thereof.
'I'he next step in the method herein disclosed is to insure that all portions of the surface of the overlasted marginal portion of the upper, from the heel breast line to the tip of the toe, are in a to receive the sole attaching cement, so that when the cement is applied, it will become securely bonded thereto. In the upper illustrated in Fig. l, the portions of the turnedback lining I 6 which are made up of fabric material I 'I extend at each side of the shoe from about the tip line to a point some distance rearwardly of the forward end of the shank portion of the shoe. The portions of the lasting margin of the upper which extend from this point to the heel breast line are reinforced by leather I9 which forms the quarter lining of the upper. It will, of course, be apparent that the marginal portions of the upper I 0 which are composed of fabric material I1 afford perfectly good surfaces upon which to apply the sole attaching cement and that no roughening operation will be necessary to prepare these portions for the cement, whether such portions are covered by the lining the doubler I4. 'Ihe portions of the lasting margin of the upper which are composed of lining leather with the grain side out, however, should be roughened lightly to remove the finish from the grain surface of the leather and thus render the surface suitable to receive the sole attaching cement, the roughening opera-tion being performed in the usual manner by means of a rotating wire brush or an abrasive wheel. In addition to roughening the leather portions of the turned-back lining I6, the upper at the toe por tion of the shoe, which, it will be remembered, was cement lasted with the aid of a toe plate, or binder and which will, therefore, be formed of the leather of the outer layer I2 with the grain side uppermost, should also be roughened lightly, as indicated at 3| in Figs. 2 and 3, to remove the finish and render the surface suitable to receive the sole attaching cement.
A coating of pyroxylin cement is now applied to I6 or by the marginal portion of the shoe bottom and allowed vto dry. A sole 34 (Fig. 4) is prepared for cement attachment by reducing the thickness of its marginal portion, particularly at the shank, roughening this marginal portion, and then applying thereto a band of pyroxylin cement. After the cement has dried it is activated on either the sole or the shoe bottom, or on both, with a suitable solvent, for example, with a solvent such as that disclosed in United States Letters Patent No.
" 1,959,320, granted May 15, 1934, upon an application led in the name of Walter H. Wedger. The sole is then positioned properly on the shoe bottom and placed under pressure while the sole attaching cement is setting, this pressure being applied, for example, by a cement sole attaching machine of the type disclosed in United States Letters Patent No. 1,897,105, granted February 14, 1933, upon an application filed in the name of Milton H. Ballard. Figs. 4 and 5 are fragmentary views illustrating how the shoe appears in cross section after the sole 34 has been attached, Fig. 4 illustrating a shoe in which the lining I6 hasbeen turned back to reinforce the lasting margin of the upper, and Fig. 5 illustrating a shoe in which the doubler I4 has been turned back to reinforce the upper. In Fig. 5 the upper indicated generally by the reference numeral I0 has been side lasted to the insole 22 by means of cement so that no staple appears as in Fig. 4.
Figs. 6, 7 and 8 illustrate the method of reinforcing the upper by cutting the marginal portion of the leather outer layer of the upper fuller than a normal lasting margin and turning the excess material back upon this outer layer and securing it thereto by a plurality of rows of stitching. Fig. 6 yshows an outer leather layer 36 of a multi-ply upper 38 having a doubler 40 and a lining 42. The marginal portion of the outer leather layer 36 has been cut fuller than a normal upper by a width substantially equal to the width of the normal lasting allowance of the upper or, in other words, about 1/2 or 5/8 of an inch Wider than such allowance, this fuller portion extending, as in the case of the lining, from about the tip line to the heel breast line of the shoe. The excess material of the outer leather layer 36 of the upper, indicated in the drawings at 44 (Fig. 6), is now turned back against the grain surface of the layer 36 and positioned so that the outer edge of the marginal portion 44 coincides substantially with the lower edge of the normal lasting margin of the upper.` The turned-back material 44 is then stitched to the outer layer 36 by a single row of stitching 46 whichis located in close proximity to the lower edge of the portion 44, as shown in Fig. 6. In this way the normal lasting margin of the upper 38 is reinforced by an additional layer of material from about the tip line to the heel breast line of the shoe, this material being integral with the upper and exposing a flesh surface of leather for the reception of the sole attaching cement.
After the extended marginal portion 44 has been turned back and stitched against the grain side of the leather outer layer 36 in the manner described, the upper 38 and an insole 48 are assembled on a last 50 and the shoe is pulled over and lasted in any usual manner. As illustrated in Fig. 7 the shoe may be side lasted by staples pletely through the insole. The toe end of the shoe may be lasted by cement with the aid of a toe plate or binder as previously described and the heel end, as illustrated, may be secured in lasted relation by driven fastenings, indicated at 53. The bottom filler 54 and a shank piece 56 are then applied to the shoe bottom in the usual way as shown in Fig. 7.
The reinforced lasting margin` of the multiply upper 33 now has the flesh side of the leather outer layer 36 uppermost and therefore presents an unfinished and substantially rough surface from about the tip line to the heel breast line of the shoe, this surface being well adapted to receive the cement by which the sole is to be attached to the shoe. The overlasted marginal portion of the upper at the toe end of the shoe should be roughened lightly to remove the finish on the grain side of the leather, as shown at 55 (Fig. 7), and a coating of pyroxylin cement may then be applied to the overlasted marginal portion of the shoe. An outsole 58 (Fig. 8) is prepared for cement attachment, and, after the cement on the shoe bottom and/or on the margin of the sole has been activated, the shoe and sole are properly located relatively to each other and placed under pressure while the sole attaching cement is setting.
It will be seen that by preparing a shoe upper in accordance with the method herein set forth the marginal portion of the upper, known as the lasting allowance, is not only substantially reinforced at the sides of the shoe so that it will be better able to withstand excessive strains to which it may be subjected during the pulling over and lasting operations, but the upper roughening operation, which is usually necessary in the manufacture of shoes having the soles attached by cement in which the grain surface of the upper leather is to receive the sole attaching cement, is reduced to a minimum. Consequently, the diculties heretofore encountered in making this type of shoe, namely, the weakening and tearing of the shoe upper during the roughening operation, the unsatisfactory results obtained in roughening certain reptile skins, and the difliculty in determining how much of the upper to roughen at the shank portion of the shoe, are practically eliminated.
