Ohio, a corporation of Ohio Filed Jan. 30, 1961, Ser. No. 85,572 1 Claim. (Cl. 12-142) Our invention relates primarily to childrens and infants shoes and while many of the principles involved in the steps of construction are also applicable to adu-lts shoes, slippers and the like, the modifications described herein are particularly illustrated with respect to the manufacture of childrens shoes.

It is our object to improve the structure of childrens shoes from a point of view of more easily conforming to standard size measurements while at the same time eliminating expensive labor steps so that a real economy in manufacture may be effected.

The foregoing objects and others more specifically emphasized in the following specification, we accomplish by utilizing the structure and the steps of manufacture shown in the accompanying drawings in which:

FIGURE 1 is a back plan view showing a preferred manner of securing the outsole and the one-piece seamless quarter together.

FIGURE 2 is a back view showing a preferred manner of attaching the vamp and the tongue.

FIGURE 3 is a bottom perspective view showing the upper and outsole ready for assembly on the last, the last being shown in dotted lines.

FIGURE 4 is a side elevation showing the finished shoe, the outsole being attached to the shoe bottom with heat and pressure, there being a continuous outsole from the tip of the toe to the tOp of the one-piece quarter.

Referring first to step 1 shown in FIGURES 1 and 2, the outsole is stitched approximately 1% inches from the top of the one-piece seamless quarter 2 as indicated at 3. The vamp 4 and tongue 5 are then stitched together as indicated at 6 in FIGURE 2. These operations together comprise the first step of our invention.

In the second step, the two units just completed are joined by stitching together the quarter 2 and the vamp 4 as shown at 7 in FIGURES 3 and 4. The parts, t e quarter and the vamp, as so joined together, are called a shoe upper.

The shoe upper is now ready for assembly on the last. This may be accomplished by tacking the insole 8 to the last over which the shoe is to be formed. Then the upper is placed over the last leaving about /2 inch of what we call the lasting allowance shown at 9 in FIGURE 3. This is the third step.

Adhesive is applied to both the inside of the lasting allowance 9 and to the outside of the insole 8, and these portions are bonded together; this is the fourth step.

It is in this just described step that the most important improvement results. We prefer to use a thermolaster ice which is a well known machine in the shoe industry. However, this step may be accomplished using other equipment.

The final step in forming the completed shoe is the securing of the outsole to the shoe bottom. Before the actual cementing step, a filler piece 1% should be added to the outside of the insole 8; this will keep the lasted shoe bottom flat during this final operation. Also, the outer surface of that portion of the upper which we have designated as the lasting allowance 9, and which has been cemented to the insole, is then roughed up so that the subsequently applied cement will be able to effectively bond to that surface. In the final step, cement is then applied, and the outsole 1 is secured in position on the outside of the lasting allowance 9* under the influence of heat and pressure as is customary in making shoes with cemented outsoles. Mechanically, we may prefer to use a sole laying machine for accomplishing this final step.

There thus results a completed shoe with a continuous outsole from the tip of the toe to the top of the one-piece quarter. As far as we are advised, no one has previously manufactured a shoe of this kind. Such a shoe automatically falls in a higher price range so not only the steps of manufacture are much simplified but the shoe falls in a higher price bracket.

Having thus described our method of making chiidrens shoes, what we claim as new and desire to secure by Letters Patent is:

A method of making a shoe which comprises the steps in the order named of (a) stitching an outsole to a one-piece seamless quarter at substantially a right angle, and securing a tongue to a vamp, (b) securing said quarter to said quarter to said vamp, said quarter and said vamp as so joined comprising a shoe upper, and placing an insole on a last, (0) placing said upper on said last leaving a lasting allowance, (d) forming a lasted shoe bottom by cementing the inside of said lasting allowance of said upper to the outside of said insole; (e) securing a filler strip to the outside of said insole, and (f) roughing up the outside surface of said lasting allowance and cementing said outsole thereto to form a completed shoe.
