Nov. 8, 1932. D. scHRElBER TURNED sHE Filed Feb. 8, 1930 Patented Nov. 8, 1932 DAVID SCHREIBER, F VIENNA, AUSTRIA TURNED SHOE Application led February 8, 1930, Serial No. 426,913, and in Austria February 8, 1929.

The invention relates to improvements in shoes, particularly to shoes for sporting, bathing and the like purposes. Shoes of this type are usually made with a sole of leather, textile or the like, the edge of which is folded over, hammered down and fixed to the sole by means of a rubber solution or like cement. The upper, being usually of the same material as the sole, is attached to this edge of the o sole by a seam which lies on the sole when the edge is folded over. Such shoes are usually called turned-shoes. The soles of these shoes being made of leather, textile or the like A have the disadvantage that the edge of the sole must be fixed on the sole by means of a heterogeneous or extraneous binding or sticking material. The folded over edge of the sole tends to return to its previous and natural position and the binding material loses to a considerable extent its adhesive quality because of the warmth of the feet or when the shoe is kept in stock for a long period, so that finally the edge will erect itself. Another disadvantage in shoes of this kind is that the stitches of the sole closing seam are pressed on the actual treading surface of the shoe where the stitching is subject to friction, incident to walking and is soon worn.

The objects of the present invention are to obviate these disadvantages in manufacturing the sole of a rubber sheet or plate, the edge or lip of which being folded over the interior sole surface or the edge itself and being fastened thereto by means of a rubber solution or other means through which the two rubber parts, being placed one above the other, are united or fused together to one homogeneous material. Owing to the faculty of rubber to fuse together with other rubber parts or with a rubber solution to a homogeneous mass, the edge or lip will form with the sole to which it has beenfixed a homogeneous piece in which there is no longer a binding seam. The sewn or stitched seam between the upper and the sole is thence embedded in the rubber sole and not merely attached to the folded over edge of the sole. It cannot therefore alter its positioneither alone or together with this edge, since the edge does not continue to exist as a separate part. The sewn seam remains in the interior of the shoe and cannot be pressed by the usual influences to the treading surface of the sole. By embedding the sewn seam as above stated the possibility of readily tearing out the seam n when thin rubber plates are used is avoided. This is very essential since thin rubber plates are highly advantageous especially for shoes for sporting or gymnastic purposes; When shoes are to be made with thick soles, a thick rubber plate witha thin edge or lip or several thin rubber sheets fused together of which sheets one forms an edge extending above the other sheets will be used. Half of the edge or lip will be folded over the other part of it in such a manner that it becomes attached to the edge of the thick plate or of the several smaller thin sheets fused together, forming thereby a continuation of the inner surface of the sole and becoming, after being fused with the latter, a homogeneous part of the sole itself.v

In the accompanying drawing there are three examples of the invention illustrated. Fig. l shows a side elevation, Fig. 2 represents a cross section of the shoe of one thin rubber sheet after the upper and sole have been sewn together, Fig. 3 the same after folding over and fastening the edge, Fig. t after turning the shoe, viz in a finished state and Fig. 5 a perspective View of the part in which sole and edge have become one piece. Fig. 6 illustrates a cross section of a shoe with a thick rubber sole plate the edge being formed by half of the edge or lip being folded over the remaining part of same. Fig. 7 a cross section of a shoe with a sole prepared of two rubber sheets fused together, the edge of the lowest sheet which projects above the others being at about the middle folded over the inner half of itself.

The upper a. usually made of textile fabric such as canvas, is sewn to the edge Z 0f a sole plate Z) consisting of a thin rubber sheet of a larger size than the normal sole, or to the lip d of a thick rubber plate b, or to the edge or lip Z9 of the lowest of several thin rubber sheets fused together, so that the edges of the upper sheet coincide with the edges of the sheets or lips respectively. Then the edge al, 100

d', d, of the sole is folded over in such manner that rubber bears directly on rubber and the sewn or stitched seam o which is within the edge or lip of the sole, as'shown in Fig. 2 lies on the sole covered by this edge or lip. In the examples shown in Figs. 6 and 7 it lies on the inner half of the lip or edge d and ci respectively. The edge is stuck to the sole, or the folded over part of the lip is stuck to its inner part, the whole edge or lip being stuck to the edge of the sole, by which v process, owing tothe faculty with Which Y rubber fuses together with other rubber parts the edge at the sheet or lip as such ceases to exist as a separate part, and forms with the sole` plate one homogeneous piece. The

stitched seam c therefore no longer appears as fastened to the edge of the sheet or lip, but is embedded in the sole, and is prevented from being. Worn by frictional contact with the pavement. After fusion of edge or lip and sole' the shoe is turned (Fig. 4) and is ready for use after the usual inner sole is placed in the shoe.

I claim: l

l. In a turned shoe, a sole made of material having theproperty of fusing and becoming homogeneously united to light material in contact therewith and having a fold atV its outer edge whereby the outer edge of the sole is doubled in thickness, an upper having an inwardly turned edge bearing against the said fold, fastening means extending through l the doubled fold of the sole and the inturned edge of the upper and securing them together, the said fold being homogeneously united to the sole so that said fold is integral with the sole and the bottom portiony of the fastening means of the inturned edge ofthe upper is covered by the sole and protected thereby.

'2. A turned shoe as claimed in claim l, in

which the sole is of rubber and in which the A inturned double fold of the sole is vulcanized and united thereto. i

3. Aturned shoe as claimed in claim 1, in which the sole is of rubber and in which the inturned double fold of the sole is vulcanized and united thereto and the fastening means is a row ofstitches. In witness whereof I affix my signature.
