16 Claims.

The present invention relates to the art of making shoes.

Experience has demonstrated that the use in the shoe industry of adhesives to secure permas nently the lasted upper to the insole, and the operation. Preferably, however, the opening 9 5 voutsole to the lasted shoe, produces a. very stiff is formed in the forepart of the insole in the shoe, much less flexible than the McKay shoe. manner disclosed in my application Serial N0- The realization of this has proved disappointing 665,663, filed April 12,' 1933. l p to the manufacturers that have committed them- The overdrawn margin of the upper may be lo selves definitely to the use of adhesives, particusecured to the lasting flange of the insole by larly those that make shoes for women, who any of the Well known mediums, such as tacks, generally demand flexible shoes.

' Fig. 5 is a view in sectional elevation'onl'the line 5 5, Fig. 4. x

Referring to Fig. 2 after the lasting operation, the lasted shoe comprises an upper 6, (which term is used .herein to inc1ude-the lining materials), which is secured in overdrawn position to the lasting flange of an insole 1 mounted on the bottom of a last 8. The lforepart of the insole is provided with an opening 9 through which the bottom of the last 8 may be observed. Preferably the margin of the upper around the forepartof the lasted shoe is trimmed to the 4 edge of the aperture 9. y Y,

The opening 9 may be formed in the forepailt of the insole either before or after the lasting thereto. During this tucking operation a portion of one face Il of the cover I0 is spread 4 smoothly over the bottom of the last 8 thus in'- suring the positioning of the face I I of the cover vsubstantially flush with that face of the insole which is exposed to View in the finished shoe or to which in some shoes there is secureda lining (not shown) which engages the sole por.- tlon of the sock of the wearer. The adhesive applied to the vertical Wall of the opening 9 is designed to secure the cover I0 permanently thereto. The adhesive applied to the margin of the overdrawn upper adjacent the opening 9 is. designed to secure the cover Ill temporarily thereto. A

When the cover lil is secured in position as shown in 3 it forms a cup (Fig. 3) in which is 55 v outsole permanently,

forated, is died out from a sheet to a size, somewhat smaller than the opening 9, so that it does not completely illl the cup formed by the cover tions of use under the treading pressure of the I 0. One face of the sponge-rubber pad I2 may be secured to the face I3 of the cover I0 opposite its face II.

Then the outsole I4 is placed in position over the bottom of the lasted shoe and secured thereto by an adhesive, care being taken to prevent the outsole from being coated with adhesive in that portion adjacent the/pad I2; Preferably, the adhesive employed to secure the outsole to the lasted shoe is suliicient to hold the outsole on the lasted shoe during the subsequent shoe mak-r ing operations, lbut is not sufficient to act as a permanent fastening means for the outsole during wear. l

The lasted shoe having the outsole temporarily secured `thereto is then subjected to a stitching operation in which stitches I5, preferably lock stitches, are inserted through the lasting flange of the insole 1, the overdrawn margin of the upper B, the marginal portiomof the cover I0, and the outsole` I3, preferably from a point -back of the heel breast line on one side of the shoe to the corresponding point on the other side of the shoe.

As shown in Fig. 3 the sponge-rubber pad I 2 depends from the cover. The peripheral' edge of the pad I2 is not secured to the vertical side 0f the cupformed by the cover I0. As 'the cover I0 is secured to the insole 'I only along the vertical wall of the opening 9 the face II of the cover I0 bulges upwardly and thus maintains thepad normally in contact with the outsole only along the peripheral corner adjacent the bottom face of the pad and its peripheral edge. The pad I2 is secured neither to the insole nor to the outsole. The pad is thus free to accommodate itself independently of the' insole and outsole to the varying condiwearers foot transmitted to the pad through the cover. I'his feature, combined with the lock stitches which alone unite the upper, insole and ible shoe.

What is claimed as new. is:
