FORCE-LASTED SHOE WITH END STIFFENER AND METHOD 0F MAKING SAME Filed June 5, 1945 2 Sheets-Sheet 2 Patented Apr. 19, 1949 FORCE-LASTED SHOE WITH END S'IIFFENER AND METHOD F MAKING SAME Jacob S. Kamborian, West Newton, Mass. Applicatie June 5, 1945, serial No. 597,506

This invention relates to an improvement in footwear and in the method of making footwear and more particularly to an improvement in shoes and the method of making shoes, which shoes can be made quickly and easily by force-lasting the assembled upper and sock lining, securing a midsole to the sock lining, wiping in and cementing the lasting margin of the upper to the midsole and cementing an outsole to the midsole and to the wiped-in lasting margin. The present in vention represents a further development of the invention disclosed in the copending United States application of Kamborian, Serial No. 527,101 filed March 18, 1944, Patent No. 2,450,666 granted October 5, 1948.

One feature of this invention resides in the fact that the sock lining of the shoe is' attached at the heel to the lining of the quarter of the upper, is free at the toe from the vamp of the upper but is secured by stitches to the vamp rearwardly of the free toe portion.

Another feature of the shoe resides in the fact that the heel is provided with a counter inserted between the lining and outer ply of the quarter. such counter preferably being provided with a flange in the form of a horseshoe bonded to a lmidsole over the joinder of the quarter lining and the sock lining, thereby dening a recess in which the heel of the wearer is received.

Still another feature of the shoe resides in the fact that the sock lining, not being attached to the upper at the toe of the shoe, thereby affords easy access to the inner face of the upper to facilitate the application of a toe box or other stiiencr after the upper and sock lining have been assembled.

Further features of this invention reside inthe fact that the shoe may be provided with a storm welt by which the appearance of the shoe is improved, and in the method of making the shoe.

These and other features will be pointed out in detail in the following description of this invention as embodied in shoes selected as two embodiments of the invention and illustrated in the accompanying drawings in which:

Fig. 1 is a view in elevation of a shoe representing one embodiment of this invention;

Fig. 2 is a longitudinal section of the shoe shown in Fig. 1;

spacesbetween the elements being exaggerated for the purpose of clarity; y

Fig. 7 is a perspective view of the shoe in the inverted position after the last has been introduced and before the lasting margin of the upper has been lasted, the heel portion only of the midsole being shown;

Fig. 8 is a. view, similar to Fig. 1, of a shoe representing a second embodiment of the invention;

Fig. 9 is a plan view of the outsole of such shoe in condition for assembly with the other parts of the shoe;

Fig. 10 is an enlarged cross-sectional view taken along the line Ill-l 0 of Fig. 8; and

Fig. 11 is a fragmentary section illustrating an outsole of further modified type.

I'he shoe I comprises an upper 2 which consists of a vamp 3 and a quarter 4, a sock lining 5, a midsole 6 and an outsole 1. The vamp 3 in the illustrated embodiment is not lined while the quarter 4 is provided with a lining 8. A lining for the vamp also may be provided if desired with-'- out departing from the spirit and scope of this invention. v

The sock lining 5 is provided at each side with two severings in the margin such severings being shown in the drawings and referred to herein as notches 9 at opposite sides of the forepart and slits I0 adjacent the breast line of the heel. The upper 2 and the sock lining 5 are assembled by the use of stitches, mechanical fasteners or the like which attach the heel portion of the sock lining, between the slits l0, to the lower edge of the lining 8 of the quarter 4, and the portions of the sock lining, between the notch 8 and the slit l0 at each side, to the4 lower edge of the -lining 8 of the quarter and the lower edge of the vamp 3. This assembly follows in general the usual practice followed in the manufacture of that type of shoes known in the trade as California, force-lasted or slip-lasted, and results in a unit into which a last is forced.

The introduction of the last into the unit i. e. forcelasting, places the upper and the area of the sock lining joined thereto under tension.

The upper 2 is vamped"-i. e. the rear edge of the vamp is secured to the forward edge of the quarter between the lining and outer ply thereof by one or more rows of stitches S-either before the sock lining is attached thereto, or after the sock lining has been attached to the lining of the quarter and before the sock lining is attached to the vamp.

As shown in Fig. 7, the portions of the margin of the sock lining that are attached to the vamp 3 and the lining 8 extend downwardly and in seam, but without any implication that the shoe herein disclosed is a Goodyear welt shoe or that the rib necessarily comprises stitches as the means for uniting its constituent plies. This rib or inseam Il together with the unattached lower edge of the vamp at the toe denes a shallow cavity i2. The lining 8 terminates at the edge of the sock lining but the lower marginal portion of the vamp 3 extends beyond that edge to form a lasting allowance. The stitches I3 attaching the vamp 3 to the sock lining are-visible at the sides of the shoe.

After force lasting the upper and insole unit, the midsole 3 is secured to the sock lining within the chamber i2, preferably by bonding it to the under surface of the sock lining by a suitable adhesive. The midsole 8, which is of a soft, resiiient material such as cork, felt, or fiber, is of such dimensions that it will substantially fill the chamber l2, with its under surface in the plane of the edge of the inseam or rib While the midsole is preferably cut from sheet material it is contemplated that it may be of other types of material, as for example moldable plastic materials which are placed in the chamber l2 and levelled off to provide a flat bottom in the plane mentioned above.

The vamp 3 and the quarter 4 comprise lasting margins that arewiped in over the inseam or rib against the bottom surface of the midsole 6 and secured thereto preferably by suitable adhesive. The outsole I is thereafter laid onto the under surface of the midsole 6 and the outer surface of the'wiped-in lasting margins and secured thereto in any desired manner preferably being adhesively bonded thereto.

If the shoe is to be provided with a counter I I, that element is inserted between the quarter l and the lining 8 thereof, either before or after the upper and sock lining has been force-lasted. In the embodiments illustrated in the drawings, a counter' I5 having an integral flange I6 is inserted after the unit has been force lasted. The counter has been preformed, and when inserted, the flange I6 extends over that portion of the inseam or rib Ii bounded by the slots III and is adhesively bonded to the midsole I. The flange Il is in the shape of a horseshoe so that the center of the sock lining and midsole at the heel is unsupported and in consequence the weight of the wearer will depress and form a recess which receives the heel of the wearer'.

A stiifener at the toe may be provided after the sock lining and upper unit has been made and before the midsole 6 has been applied and the last has been introduced. The free toe of -the sock lining is turned back to provide an opening through which access may be had to the inner surface of the toe of the upper, see Fig. 2. and the toe box I1, inserted through the opening thus provided, is adhesively affixed to the inner surface of the toe of the upper. Before the last is inserted, the toe portion of the sock lining is restored to its original position, and after lasting becomes adhesively united to the midsole 6.

If, in accordance with the usual practice. the

toe box is of moldable, plastic or thermoplastic material, the last, when introduced into the unit. will mold the toe box into conformity with the toe of the shoe and by the time the shoe has been completed and the last removed the toe box will have set. The toe box material may be activated by the application of heat, for example, by subjecting the shoe to the influence of ultra red rays. This invention thus renders unnecessary the procedure of ailixing the toe box to the vamp before assembly as disclosed in the copending application and permits the application of the toe box after the upper and sock lining have been assembled. A heel wedge 1a may be assembled with the midsole before the outsole is applied.

The procedure of providing stiffeners outlined in the copending Kamborian application Serial No. 561,282, med-October 31, 1944, now Patent No. 2,414,104 may be employed if desired. A shank stiiener I8 of any well-known type may he1 provided between the midsole 6 and the outso e 1.

'I'he shoe i9, shown in Fig. 8 as a second embodiment, differs from that described above solely in that the outside 20 thereof is over-sized and is provided with a storm welt 2|. 'I'he storm welt 2| is of a textile fabric, leather, plastic or other resilient material and is of the cross sectional contour shown in Fig. 10, having an outer wall 22 and an inner Wall 23 'normally spaced apart. 'I'he outer wall 22 is secured in any suitable manner to the outsole 2li along its edge before the latter is incorporated in the shoe. As shown in this ligure the outer wall 22 includes a flange 24 which rests upon the upper surface of the outsole and is bonded thereto as by the use of stitching, mechanical fasteners or adhesive. The strip 2| thus forms a continuous wall, enclosing a central area 25 which receives the under surface of the midsole 6 in the finished shoe.

After the upper, sock lining and midsole have been assembled as described above, the assembly is disposed upon the central area 25 of the upper surface of the outsole and adhesively secured thereto. 'lhe strip 2| is so mounted that the edges of the assembly will bear against the inner wall 23 and urge it outwardly a greater or lesser distance toward the'outer wall 22. Thus a close contact is insured between the storm welt 2| and the outer surface of the upper 2, (see Fig. l0), and the stitches I3, otherwise visible at the vamp, will be concealed. Preferably the outer surface of the upper which contacts with the strip is roughened, through abrading or otherwise, and provided with adhesive by which the inner wall is secured to the upper. The contact of the upper with the strip 2|, as the outsole and assembly are joined, is directed downwardly and outwardly upon the inner wall 23 so that the latter is pressed downwardly against the surface of the outsole as well as outwardly toward the outer wall 23. The strip 2| in the finished shoe is thereby bonded to the upper and any danger of separation therefrom is eliminated. In place of a separate storm welt, a moulded outsole Il having an integral wall 3| may be provided. (See Fig. 11).
