1 Claim. (Cl. 12-142) The present invention relates to a new and useful, simplified construction of footwear and its production.

The footwear of the present invention embodies a combination of the best features of the Compo shoe, which is a cement lasted shoe, and the best features of the sliplasted type of California construction and is essentially a slip-lasted shoe eliminating the separate wrapper and platform of the California type or style of shoe. In the invention, the sock lining of the insole is sewn in, thereby eliminating the chief fault of Compo shoes which have a tendency for the sock linings to loosen and fall apart. In accordance with the process or method of the invention, the flexibility of the ship-lasted California process is retained together with the appearance of the Compo shoe and with the added feature that the sock lining is a permanently locked-in part of the shoe. Thus, shoes and slippers manufactured in accordance with the invention overcome the disadvantages of prior shoe and slipper constructions, particularly those of the Compo and California types, and provide important advantages and features not heretofore obtained.

One of the objects of the present invention is to provide an inexpensive shoe or slipper which has unusual qualities of appearance, wear and durability and which is produced in accordance with a novel method consti tuting a part of the invention.

Another object is to provide a shoe or slipper which can be made rapidly and inexpensively by mass production while still providing a shoe or slipper which has marked advantages over prior types of construction.

A further object of the invention resides in the production of a synthetic plastic shoe upper having a fabric lining and an inexpensive insole provided with a fabric sock lining and wherein the fabric lining for the insole is of larger size than the insole, thus providing a peripheral portion which can be turned under and stitched to the shoe upper, thereby providing a shoe or slipper which has a vastly superior appearance and wearability than shoes or slippers made in the standard manner.

Other and further objects and advantages of the invention will be understood by those skilled in this art or will be apparent or pointed out hereinafter.

In the accompanying drawing wherein I have illustrated a preferred embodiment of my new shoe or slipper and the steps involved in the production of the same,

sole 10 made of cardboard or any other suitable or similar material is adhesively assembled with a fabric sock lining 11 of the same shape but of larger size so that, as shown in Fig. 1, the lining 11 has a peripheral portion extending around the insole and beyond the same. The insole 10 and fabric sock lining 11 are secured together throughout their contacting surface areas by means of any suitable or conventional adhesive, the specific nature of which does not constitute a limitation upon the invention.

The body of the shoe is separately fabricated or manufactured and primarily consists of a plastic coated fabric in the nature of vinyl or pyroxylin or other conventional upper shoe material 12 such as leather, fabric, straw, velvet, etc., also provided with a fabric lining 13. The fabric lining 13 of the upper 12 is preferably, but not necessarily, of the same material as the fabric sock lining 11 for insole 10, but may, if desired, be different or of contrasting materials, but, for best results, I have found that they should be of the same material, both for improved appearance and for simplicity and ease of manufacture. The generally oval-shaped opening 14, as shown in Fig. 3, is for the admission of the form or last over which the shoe is completed and which, in the finished shoe, represents the opening for the insertion of the foot. This opening 14 is provided with a conventional binding strip, usually of fabric, which is sewn in place. The numeral 15 designates the conventional seam at the back of the shoe Where the ends of the upper come together and, in the finished shoe, this seam is covered by a strip of the same material as the upper, sewn in place thereover.

The next step in making the shoe or slipper is to assemble the insole 10 and its fabric sock lining 11 with the upper 12 and the accomplishment of this is illustrated in Fig. 5. In this figure it will be noted that the peripheral portion of the lining 13 and also the subjacent portion of the upper 12 are fiat and as yet in an unfinished In order to assemble the shoe parts in the intermediate stage shown in Fig. 5, the same are assembled in the illustrated position and then sewn together in such manner that a row of stitching 16 passes through, from the underside and looking down on Fig. 5, the fabric sock lining 11, the fabric lining 13 and the upper 12 (see Fig. 6), thereby securely maintaining these parts in the relative positions shown. The sewing operation can be carried out on a standard shoe-making stitching machine. This relationship is further illustrated in Fig. 6, which shows the manner in which the stitching is arranged just beyond the periphery of the insole 10, so that subsequently, and as shown in Figs. 7 and 8, this stitching becomes concealed from view due to the fact that the peripheral portion of the upper 12 is folded over and secured under the insole 10 around the peripheral portion thereof by means of any suitable adhesive. It will be observed that, when viewing the interior of the shoe, the row of stitching 16 is not only concealed from view but is locked in and out of contact with the wearers foot so that no wear is placed upon such stitching, this not only improving the durability of the shoe but also the appearance thereof.

When the peripheral portion of the upper 12 is in- Patented Aug. 16, 1955.

applying and securing in place the outer sole which may be composed of any of the usual materials employed for this purpose and the specific nature of which does not constitute a limitation upon the invention.

The appearance of the finished shoe looking into the interior thereof is illustrated in Fig.9, from which it will be noted that the line of stitching 16 is under the edge of the insole 10 and is not visible and not subject to wear when the shoe is worn. This stitching and its disposition constitute a particularly novel and useful feature of the invention.

In this manner I have been able to produce a unique construction of shoe or slipper in a simple, economical and commercially practicable manner while at the same time producing a shoe or slipper which has a markedly improved appearance and greater useful life. As a manufacturer of shoes, I am well acquainted with the many different styles and methods of construction of such types of shoes and slippers and to the best of my knowledge and from my experience no shoe or slipper has ever been constructed in accordance with the present invention or by the present method as defined inthe appended claim.

I claim: A method of making a shoe or slipper comprising providing an upper with an adhesively united fabric lining, assembling therewith an insole having secured thereto a fabric sock lining of larger size than the insole to provide an extending peripheral portion, stitching the peripheral portion of the sock lining to the upper just beyond the peripheral edge of the insole, Wiping in the peripheral portion of the upper on to the underside of the insole and adhesively securing said upper portion to the insole, and thereafter finishing said shoe.
