ovnnsnon AND Pnocnss or Application led June 3,

This invention relates to overshoes ofthe arctic type. Such overshoes include a rubber bottom and cloth top with fastenings, usually buckles for securing the opposite edges of the upper around the ankle of the wearer. The cloth upper usually includes an outer fabric and a lining united thereto by an intermediate coating of rubber, and the buckles are secured to straps which are 10 anchored between the lining and the outer fabric,both ends of each strap being secured between these fabric pieces so that the straps form loops which project beyond theedge of the upper. Due to the presence 'of these loops, it has always been the practice to either leave the 'edges raw or unbound atthe top and alsoat the front of the s hoe, or else to bind the edge with a thread binding or overseaming. l y 2.0; When the' edges were lefty fraw or unbound there was atendency of the fabric, especially if of the woven type, to fray, and when the edges were finished with a thread binding or overseaming, finished edge was e expense and made anxobjectionable appearance. v

The chiefobject of the present invention is to improve the construction of the overshoes of the type mentioned, with a view to efectually preventing the fraying of the exposed edges of thelupper and providing an overshoe of improved appearance.

The invention also aims tov devise a process of manufacturing overshoes which will attain the end just mentioned withoutadding materially to the expense of manufacturing the shoe.

The nature of the invention will'be readily understood from the following ,descrip- 40 tion when read in connection vwith the accompan 'ng drawings, and the novell features will be particularly pointed out in the ap ended claims. p gf the accompanying drawings,

seam 6. It should be understood, however, 'A'

that this invention also applies to a shoe with a' one piece upper, in which case there 1s no seam at the back. The parts forming the outer fabric of the upper are .securedv to inner lining' pieces 7, 8 and 9 by means of an intermediate coating of rubber. The

side pieces 4 and 5 are also adhesively united to afabric piece 10 which'forms part of the shoe. A portion of the member 10- is also secured to the lining pieces 7 and 48. The construction so far described is that of the ordinary type of overshoe.

According to thepresent process the front and top edges of the side pieces 4 and 5 are folded as is shown in Figure 3. The fold- -ing is done after the side pieceshave been cut out and before they are secured to .the lining. The fold is approximately oneeighth inch in width and can be performed either by hand or by one of several suitable folding machines known commercially. It is then preferable to apply a coating'of rubber cement to that portion of the edge which' is folded over, and .later when lining pieces 7, 8 and 9 are secured to the side pieces, the gum coating on the side pieces readily adheres to the cement on the folded portion of parts 4 and 5 and a firm union isl thereby secured. Fastener supporting loops 13,13 are anchored between the lining and outer `fabric of theu'pper in the customary -way. The invention is not limited necessarily to applyy a-'coat of cement to the folded 4portionof the edges, and although we prefer to' bring the liningpieces veven with the folded edge, it is possi le to eliminate the application of the .coat of cement and only bring the piecesup to, but not over, the folded portion of the outside'edges. We

alsoprefer 'to treat the top edge of the gore whichis the V-shaped piece 12 in Figure 1, 'in a similarfashion by folding the edge and cementing, 'as-described.'

' The remaining manufacturing operations may becarriedv out in any suitable manner.

After vassembling the various parts of the upper, the remainder of I the arts of the shoe are assembled in proper re ationship to each other on a last and the shoe is vulcanized. n

The completed shoe is shown in Figure 1 audit wil much neater appearance thanA shoes made "either with a raw or unbound edge o1' shoes in which the edges are finished by a thread bind or overseaming. The exposed edges of the parts 4 and 5 of the upper and alsothe top edge of ,the ore are'eii'ectually prevented from fraying y this method of folding the ed e and makes a much neater and more finis ed appearance than can be produced otherwise. A stronger edge i's obtained thereby allowing the elimination, in some cases, of certain inside sta s or reinforcements which are usually use in the top construction to revent tearing of the fabric .gat the edge an so forth. A more durable Vtop is obtained as the double thickness of the top material is more resistant to wear than the unbound edge or the thread bound edge. Also as the folding and cementin operations are very readily performed elther by machine or hand, the present process involves practically no increase in cost over.

the ordinary method of leaving the edges unbound and is moreeconomical than the method of thread binding or overseaming.

Modifications of the invention maybe resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is.: i 1. An overshoe of the arctic t pe comprising a rubber bottom and a rub rized cloth upper, said upper including outer and inner plies of fabric adhesively secured together, astening means secured between said plies be observed that it presents a at one of the front edges of said `upper to facilitate the fastenin of the shoe about the ankle ofthe wearer, t e edges yof the outside lies being folded over and the inner plies eing adhesively secured at the edges -to the outer plies.

2. An overshoe of the arctic t pe comprising a rubber bottom and a rub erized cloth upper, said upper including outer and inner plies of fabric adhesively secured together, fastening means secured between said plies at one of the front edges of said upper t0 facilitate the fastening of the shoe about the ankle of the wearer, the edgesr of the outside plies being folded over and adhesively secured.

3. That improvement in the process of manufacturing arctic overshoes, which con- 1 sists in cutting the parts' of the upper out of suitable rubberized fabric, folding over the' edges of the quarters and gore, and securing rubberized fabric pieces to the inner surfaces of said uarters with the edges of said inner pieces ocated adjacent thel edge of the quarters, and then completing the manufacture of the said overshoe'in 'any suitable manner. h
