1 Claim.

This invention relates to shoes. More particularly my invention relates to an improved shoe construction of the type provided with platform outsoles and to the method of making the same.

One of the objects of my invention is to provide an improved shoe construction of the character described having novel means for attaching and holding in position a platform sole.

Another object of my invention is to provide a welt shoe construction having a platform sole.

A further object of my invention is to provide a shoe construction of the character described which shall comprise relatively few and simple parts, which shall be easy to assemble, which shall be relatively inexpensive to manufacture, which shall be rugged in construction and yet neat in appearance, and which at the same time shall be a general improvement in the art.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplifled in the construction hereinafter described, and of which the scope of application will be indicated in the claims.

Fig. 16 is a view similar to Fig. 15, but illustrating the manner of attaching a platform sole to the shoe; and

Fig. 17 is a sectional view of a portion of a. l

shoe illustrating still another modified form of my invention.

Referring now in detail to the drawings, there is disclosed a shoe 20 constructed in accordance with my invention and comprising an upper 2| of material of the type generally employed in the art, a leather insole 22, a midsole 23, and a platform outsole 24 made of any suitable resilient 'materiaL 'such as for example sponge rubber.

The outsole 24 is preferably of the pre-formed type of platform sole, such as is shown and described in my co-pending application, Serial No. 284,571, led July l5, 1939, and shown in Fig. 9 of the drawings.

In Figs. 1 to 12, I have shown one methodof constructing a shoe in accordance with my invention, in which the insole 22 is rst provided with a peripheral slit 26, as shown in Fig. 2a of the drawings, extending inwardly for a relatively short distance to divide the edge portion of said insole into upper and lower lip portions 2l and 28, respectively. The lower lip portion 28 is turned down to the dotted line position 28', as shown in Fig. 2a, and in the full line position 28", as shown in Figs. 2 and 6. The upper 2| is then placed alongside of the newly formed edge of the insole 22. Overlying the upper 2| and adjacent the bottom edge thereof is provided an apron member 30. A welt member 3| is disposed with one edge thereof contactively engaging the apron 30. The welt member 3| is arranged to project outwardly in a direction substantially parallel to the insole 22 and having the bottom surface 3|a thereof substantially flush with the lower edge of the lip portion 28 and the lower edges of the upper 2| and apron 30. t plurality of tape members 32 are employed at spaced distances around the shoe, to temporarily hold the apron in a position closely adthe upper 2i and the insole lip 1th', as kclearlyshown in Fig. 6 of the drawings.

After the above described operations have been performed, While the upper is positioned on the last as shown in Figs. 4 to '1, the midsole Il is properly superimposed on the insole 22 and welt 3l. The midsole 23 is of greater width than the insole 22, so as to have the edge thereof lie hush with the outer edge of the welt Il. Said midsole `23 is attached directly to the welt by stitching ll passing through the welt and midsole, as" clearly shown in Figs. 2 and 11. During the operation of attaching the midsole 23 to the welt si. the apron 30 is still temporarily held as shown in Figs. 4, 6 and 7, so as not to interfere with the last named operation.

The platform outsole 24 is now ready to be sttached to the shoe. To this end, the outer sur-- face of the midsole 23 is provided with a layer of cement'or other suitable adhesive well known to the art, Vand at the same time the top surface 23a, of the'platform sole is also provided with an adhesive or cement layer. The platform outsole 24 is then brought into eifective engagement with the cemented surface of the -midsole 2l and pressed to permanently hold the same attached. To further insure the permanent attachment of the outsole 24 Ato the shoe, the etposed surface "a of the apron 30 is provided with a coating of adhesive or cement, after which the temporary holdingtapes 32 are removed from their position. as shown in Figs. 4 and 7, so that the shoe constructionon the last appears as in Fig.` of thedrawings. The apron is then brought over so that a portion thereof overlaps and becomes adhesively attached to the edge of the platform sole 24, as clearly shown in Figs. 2, 3 and i2 of the drawings. i v

, It will be clear from the above described construction that I have provided a welt shoe in whicha platform sole is attached theretoiin such manner that the said sole will remain in attachment and not become loosened therefrom. The apron 3l. attached directly to the insole and the upper by means of the welt Il serves to ilrmly hold the platform solo I4 against displacement and at the same time neatly iin'- ishes off the shoe, hiding from view the weit and.

the midsole. The space between the insole 22 riassupper 42, the insole 4l and the midsole 4I. In

this form of my invention the platform outsole 24 may be attached in the same manner as that. i shown and described in connection with the Figs.

i to 12 form of my invention.

AIn Figs. 15 and 1li'l I have shown my invention as applied to the type of shoe construction in which' 'the welt is omitted. In this form, I

,provide an insole l., to which there is attached the inturned edges of the upper li and the apron l2. Any suitable attaching means may be provided, such as the stapling or stitching Il passing through the 'apron l2, the upper Il and the insole ll. After the above described operation,

the f midsole I4 is then superimposed, as shown,

arid is attached to the shoe by stapling or stitching Il passing through the midsole I4. the apron l2, the lupper Il and the insole Il. The said stitching i3 and i! is preferably of the type known as McKay or lock" stitching. The

above described operations in connection with.

this form of my invention may be performed while the shoe is of! the last. The platform outsole 24 may be attached to the midsole in the same manner as that described in connection with the Figs. 1 to 12 form of my invention, in which the apron l2 is utilized to hold the outsole 24 in permanent attachment t0 the shoe. A

In Fig. 1'1 I have shown another modification of my shoe construction, made in a manner simichanges might be made in the embodiments and the midsole 23 may be filled in by any 31111;.`

able filling' material, such as cork 2l, in the manner well known to the art.

It is apparent that, if desired, the upper may be adhesively attached, cemented or. vulc'aniaed to the insole and outsole and the apron disposed wholly exterlorly of said shoe in contactive en. gagement with the upper and outsole, so that said apron may aid in holding said outsole against displacement, as aforesaid.

-Ih Figs. 13l and 14, I have shown a modified form of my invention. in which the insole 4I and the midsole 4i are substantially of the same sin and in which the upper 42 and tbe apron 4I are lar to that described in connection with the Figs. 15 and 16 form of my invention, except that the midsole tl is of larger dimensions than the midsole M shown in said figures. The said midsole 8l thereby projects laterally a short distance beyond the upper li, to form a welt-simulating ledge Il. 1

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various above set forth, such as for example the substitution of adhesive attaching, cementing or vulcanizing for stitching, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative yand not in a limiting sense. y

Having thus described my invention, I claiin ss new and desire to'secure by 'Letters Patent:

In a method of'assembling a shoe having a resilient outsole made of sponge rubber or the like, those steps for attaching said outsole to said shoe which comprise securing an edge portion of an apron to said upper to yleave a free apron portion. .temporarily securing said free apron portion to said upper, applying adhesive to the exposed surface of said free apron portion, detaching said free apron portion from said upper, and then adhesively attaching said free apron portion to the edge of said outsole.
