Patented Jan. 3, 1933 "UNITED STATES PATIENT OFFICE JOHIN TABER, OF SOUTH BEND, INDIANA, AssIGuo T ,MISHAWAKA RUBBER AND WOOLEN MANUFACTURING cor/manner misnawaxn, INDIANA, ,A CORPORATION F IND NA OVERSHQE Application filed June 15,

My invention relates to overshoes of the excluder type wherein the leg covering portion is provided at each side with surplus inaterialin the-form of forwardly extending expansible flaps which permit enlargement of the upper for inserting and removing the foot, theseflaps being detachably connected across the front of the overshoe to hold the upper or leg covering portion of the overshoe in contracted leg fitting form, and my present invention has reference'more particularly to the construction of the expansible side portions or flaps by providing folds in the leg encircling portion of the upper so that these folds conform to, lie against and connect across the front of the overshoe.

The principal objects of my inventionare tov provide an overshoe of the excluder type and method of making same wherein expansibility is provided in an improved manner; to insure maximum enlargement of the leg encircling portion with a minimum amount of material; to construct the upper with a one piece continuous facing around the leg por- 25 tion and joinedtogether at the back and having fullness at the sides forming folds for expansion and contraction which connect across the .frontof the overshoe; to insure vulcanization and permanent shaping of this facing 30'blank in a neat form fitting manner by securing same to a lining which is fitted snugly around the last and slitted after vulcanization at the folds; and in general to provide an improved overshoe *of the excluder type.

On the drawing:

Fig. 1 is a perspective view of an overshoe constructed in accordance with my invention;

'Fig. 2' is a side view of the lining as assembled on the last;

Fig. 3 is an'enlarged sectional view on the line 3-'3 of Fig. 1; and r Fig. 4 is an inside view of the assembled leg encircling blank from which the expansion fol'dsare formed.

Referring to the drawing, the reference numeral 5 indicates the foot portion of the overshoe, 6 the overshoe top, and 7 the upper portion of the. lining on which the parts are assembled, the lining being of form fitting 50-shape with slits 8 at the sides to permit en- 1931. Serial mpseamo.

iargement for inserting and removing the.

foot. The overshoe top 6, which is continuous across'the front and along the sides and joined together at the back, is adhesively secured to andof a form corresponding to the lining 7 except at the slits 8 where the overshoe top 6 has excess material providingfolds 9 to permit enlargement of the upper, and these folds normally extend forwardly from the respective slit 8 and lie compactly against the front portion of the overshoe upper, in which position their forward extremities :are connected by the ladder type buckles 10 or any other suitable type of fasteners.

This not only affords a neat and simple structure that is convenient to manufacture, but it insures a dependable waterproof closure at the places where expansion occurs as the expansion members 9 are merely folds at intermediate places in a continuous upper blank which avoids the joints and seams that are customarily employed in making the expansible portions of overshoes of thi-scharacter.

In constructing this overshoe, the lining, which preferably consists ofthe main section 7 and a toe covering section .11 joined together at the front and down thesid-es by the tape 12, is stretched around the last 13 and joined together at the back in the usual manner and hasthe loweredge lasted over an insole (not shown) to afford a form fittingbody upon which toassemble. the rest ofthe overshoe parts, the lining sections '7 and 11 being provided on the outer sides with a skim coating 13 of rubber composition and the tape 12 being frictioned to facilitate the uniting of the other overshoe parts therewith.

The blank which-forms the overshoe top 6 is then applied around the legcoveringpor tion of the lining on the last, this blank having been previously prepared in substantially the form shown in Fig. 4 with-a facing layer 14 of rubber on a layer of fabric 15 over the upper edge of which latter the rubber 1a is turned as indicated at 16 to finish thetop edge of the overshoe, and this blank preferably having at each side of the middle, a fabric reinforcing-17 on the'inner sideat the location of and in the form to line the fold 9 which is formed from the respective portion of the said blank.

in applying the blank of Fig. 4 to the lining of Fig. 2, the middle portion of the blank between the fabric pieces 17 is stretched on and adhesively secured to the front of the leg portion of the lining Z11 with the gunnned forward edges 18 of the fabric 1'? ad hesively secured to the lining at the sides. The portions of the blank to which the reinforcing fabrics 1'? are attached are then folded substantially along the lines 19, whereupon the gummed rear edges 20 of the fabric pieces 17 are adhesively secured to the lining 7 slightly to the rear of the line along which the gumined edges 18 have been attached thereto, and thereupon the portions of the blank beyond the gummed edges 20 are adhesively secured to the lining, and the end edges of the blank overlapped or otherwise secured together at the back of the lining.

The end edges of the blank may, if desired, be secured together before the blank is ap plied on the lining 711, in which event the blank, which is then in a tubular form, is slipped down onto the leg portion of the last which has the lining 711 thereon, and either the front or rear portion of the blank is first applied in the proper place on the lining and rolled down in adhesive contact therewith, after which the other portion of the blank is located in proper position and rolled down in adhesive contact with the lining, the gummed edges 18 and 20 likewise being rolled down in adhesive contact with the lining, in which operation the gummed edges 18 and 20 of ach fabric reinforcing 17 are brought close together in proper position on the lining, and the portions of the blank "etween the respective gummed edges 18 and 20 being accordingly folded outwardly in tapered pocket form.

After the overshoe top 6 has been secured in place, the foot covering 5, which has a rubber facing corresponding to that of the overshoe top, is adhesively secured on the foot portion of the lining with the upper edge of the foot covering overlapping the lower edge portion of the overshoe top 6 and rolled down firmly to insure a thorough sealing of the joint, said foot covering 5 preferably having a pointed portion 21 which extends upwardly between the lower portions of the folds 9, and after this foot covering is secured in place, the sole 22 and heel 23 are built up in the usual manner.

The folds 9 are provided with any suitable fasteners for detachably connecting the forward edges across the front of the overshoe, these fasteners preferably being applied before vulcanization and employed during the curing to hold the folds down in a close compactmanner against the front of the overshoe so that the folds will set in vulcanization in the form that they are to assume when the overshoe is worn, the fasteners that I prefer to employ being of the ladder type, as shown at 10, with. attaching tabs 24 adhesively secured to the exterior of the folds.

In preparing the overshoe for vulcanization with these fasteners, the sides of the folds that will come next to the front of the overshoe and the front of the overshoe as well are thoroughly talcumed to prevent adhesion in vulcanization, after which the folds 9 are drawn forwardly and laid down snugly against the front of the overshoe and while in this position the tabs 2% of the fasteners 10 are adhesively secured to the outer sides of the folds 9 in position so that the fasteners, when connected, will hold the folds 9 in the desired compact form fitting manner.

The overshoe is then vulcanized with the fasteners 10 connect-ed and holding the folds 9 in the desired position and after vulcanization the fasteners are released and the lining slitted at each side of the upper, substantially along the lines 8 of Fig. 2, between the places where the edges 18 and 20 of the respective fabrics 17 are secured to the lining, and this permits the folds 9 to open up and the overshoe upper to be expanded and the overs ice to be removed from the last.

While 1 have shown and described my inadhesively securing a leg covering blank onto- 1 the lining with the ends joined together at the back and with a loose section of the leg covering blank at each side of the leg portion of the lining in the form of a fold, then joining the folds across the front of the leg portion, then vulcanizing the overshoe and after vulcanizing slitting the lining at each side of the leg portion at the location of said folds.

2. The method of making an overshoe which comprises applying a form fitting lining on the foot and leg portion of a last, forming a leg covering blank with a pair of laterally spaced substantially V-shaped fabric members on the inner face thereof remote from the ends, then adhesively securing said blank and the lateral edges of the V-shaped fabric members onto the lining with the ends of the blank joined together at the back and the portions of the blank to which the V- shaped fabric members are attached folded outwardly in the form of a pocket at each side respectively of the leg covering portion of the lining, then holding the pocket folds forwardly against the front of the overshoe and vulcanizing the overshoe, and then slitting the lining at each side of the leg covering portion at the location of the pocket folds.

3. The method of making an overshoe which comprises applying a form fitting lin ing on the foot and leg portion of a last, forming a leg covering blank with a pair of laterally spaced substantially V-shaped fabric members on the inner face thereof remote from the ends, then adhesively securing said blank and the lateral edges of the V-shaped fabric members onto the lining with the ends of the blank joined together at the back and the portions of the blank to which the V- shaped members are attached folded outwardly in the form of a pocket at each side respectively of the leg covering portion of the lining, then oining the pocket folds across the front of the leg covering portion of the overshoe, then vulcanizing the overshoe and after vulcanization, slitting the lining at each side of the leg covering portion at the location of the pocket folds.

4. The method of making an overshoe which comprises applying a form fitting lining on the foot and leg portion of a last, adhesively securing a leg covering blank onto the lining with the ends joined together at the back and with a loose section of the leg covering blank at each side of the leg portion of the lining in the form of a fold, then adhesively applying a rubber faced foot covering on the foot portion of the lining with the upper edges of the foot covering overlapping the lower edge of the leg covering blank, then holding the folds forwardly against the front of the overshoe and vulcanizing the overshoe and after vulcanization, slitting the lining at each side of the leg portion at the location of said folds.
