1 Claim. l

Our present invention relates to beaded mock welting and more particularly to an ornamental and seam-lling beaded mock welting adapted for use with footwear of the McKay type of construction, and especially designed so that the bead will be automatically forced against the shoe upper by the normal pressure of a foot in the finished shoe.

At present, in footwear of the several McKay types in which the outsole, or the outsole and McKay welt or midsole, are united to a prelasted upper and insole by thru-and-thru stitching, it is generally found that the inseam stitching has a tendency to show or grin and thus detract from the appearance of the nished shoe. Such stitch grinning becomes further apparent in McKay footwear after the shoes have been worn for some time, as the upper tends to stretch away from the sole, thus presenting a most objectionable appearance.

It is to obviate this difficulty, therefore, and to assure an attractive appearing shoe that we have developed our novel beaded mock Welt which is appropriately designed to be incorporated in any and all types of McKay shoes.

Heretofore, various efforts have been made to employ devices which would conceal the inseam stitches to prevent them from showing, but such prior devices have included extra strips, made of rubber or the like, which have proven unsatisfactory in use and expensive in cost, and also rubber rapidly deteriorates.

We appreciate that welts for use in Goodyear welt footwear have been made with beading as an integral part thereof for purposes of ornamentation, and even beaded strips alone, but as far as we are advised no beaded mock welting has heretofore been developed that may be effectively applied to footwear of the McKay type of construction.

From the experience gained in extruding resilient and stitchretaining plastic welting for Goodyear welt shoes, we have determined that any shape of configuration of such plastic material may readily and accurately be supplied. Accordingly, for specific adaption to McKay footwear, we have designed a novel and useful beaded mock welt which can be applied to any shoe of McKay type construction, combines ornamental and seam-filling characteristics, and is so arranged that the bead portion thereof will be automatically held under pressure against the outside of the shoe upper.

In carrying out our inventioinwe prefer to arrange our mock Welt with a thin stitch-retaining body portion suitably tapered to approq priately fill in the seam between the upper and the outsole, welt, or midsole. Integral with the body portion and upstanding therefrom substan tially at right angles, we devise our novel curved bead, formed With'a convex outer surface which depends slightly below the lower surface of the body to provide a tensioning rib portion, and with a concave inner surface of proper contour to approximate that of the marginal edge of a shoe upper, the top of said concave surface merging with the upper end of said convex sur--jA face to afford an inturned ange to bear tightly and snugly against the Vouter surface of the upper.

We find that the combination of the resilient characteristics of the material and the construction of the bead is particularly effective in causing our mock welt to closely hug the upper when applied to a shoe, as downward pressure exerted on the upper surface of the body portion will apply force on the lower rib of the bead,v thus setting up a rotary moment, thereby forcing the inturned flange against the upper and'l retaining the same in pressured Contact with the upper.

Inasmuch as we prefer to make our novel mock welting of synthetic plastic material, we are enabled to turn out a uniform product, at an economical cost, and of any desired color. In addition, the inherent resilience of such material is peculiarly suited to an ornamental, moisture-proof, and seam-filling beaded mock welt to improve the appearance, fit, and comfort of the footwear of McKay type construction.

Further features, objects, and details of construction will be hereinafter more fully pointed out in the accompanying description and more clearly defined in the appended claim.

Referring to the drawings showing a preferred embodiment of our invention:

Fig. 1 is a perspective view of a strip of our novel beaded mock welting;

Fig. 2 is a fragmentary cross-sectional view illustrating our novel mock welt, with the bead slightly overdrawn, applied to a McKay type shoe embodying a Welt and outsole construction;

l Fig. 3 is a fragmentary cross-sectional view illustrating our novel mock welt with the bead slightly overdrawn, applied to a McKay type shoe having a midsole and outsole construction, and `Fig. 4 is a fragmentary cross-sectionalview illustrating our novel beaded mock Welt, with the bead slightly overdrawn, applied to a nailed McKay shoe.

As shown in the drawings, our novel beaded,

mock Welt, designated generally as IU, consists in a unitary strip of resilient synthetic plastic material especially designed with a relatively thin attaching body portion II and an ornamental and seam-filling bead portion I2 integral with said body II and curved upwardly at subst-ahr where the same meet the corresponding, ends of" the bead I2.

Such body II presents an ideal. stitching, surface, and the taper enables it. to. be more easily guided into stitching positionY and to be Vmore snugly tted in the seam between the outsole,y and upper, Welt and upper, or midsole and upper,

depending on the type of McKay construction-V involved.

The bead I2 is of greater thickness than the Y body U. and designed. with, convex, exterior and concave interior surfaces-the curves ofkv said sursfaces being substantially parallel thru .11h52, medial portion of their respective arcs,` and the exterior surface, having. inturned upper and lower edge portions to. provide said bead l2. with aY lower pressure-leverage rib L4. andan upper contacting iiange, 15asshownl The bead I2. hasbeeh thus. arranged so that. downward pressure on the body portion. ll adjacent, the rib Ill results in corresponding reaction on. the. ribI Ifl tocause the Ilan-geY I5 tobe automatically pressed ina lateral direction against the upper.

In Figs. 2, 3, and 4 We have illustrated ourV beaded., mock welt in attached, relation with, several modifications of McKay shoe construction, Ineachof such modications an upper IS., having the usual lining Il attached the-rein, is lasted to. an insole i8, which lasting may be eiected by tasking, stapling, or, as here shown, by ceinentingv` Inv Fig.k 2 theupper I5 and they insole It are assembled on a last, and cernentflasted together. Thereupon, the last` is` withdrawn,` and our mock, welt I0, together with the McKay welt 20, simula. taneously fed about` the. lastedl edge oi the upper L6. by suitablel guides as the` thru-and-thruA in. seam stitching, indicated at 2l., is set.

Following ther inseam-stitching operation, the outsole 22 is then applied and secured by a line of outseam stitching 2,3 thru the welt 2i) and outsole 22V adjacent the outer edges thereof. The usual finishing operations are' then performed and the shoe completed,

In Fig. 3,` we have depicted our beaded mock Wel-t I0, applied to a McKa shoe of the type embodying a midsole and outsole construction. In this form, the upper I5 and insole I3 are assembled on a last as above, cement-lasted together, and the last4 Withdrawn. Thereupon, our mock welt I0. is fed by suitable guides about the lasted edge of the upper It as the thru-andthru stitching 25 is set, uniting the insole IB, upper I6, and body portion Il. A midsole 25 is then prepared and secured to thei above by a further line ci inseam stitching 21, after which an. outsole 28 is.v incorporated therewith by means of outseam stitching 2.9- set thru the outer edges of said midsole 25 and outsole 29,. As above.- the usual finishing operations are then, performed and the, shoe completed.

In Fig. 4, wev have shown our beaded mock welt I applied toa shoe of the soscalled straight McKay type of construction. Similarly, in thismethod the upper I and insole I8 are rstassembled on a last and bonded together by cement- It lasting. VVThe last 1s then withdrawn, and our mock welt I0 suitably guided about the lasted edge of the upper I6 as the thru-and-thru inseam stitching, indicated at 30, is set, thus uniting. theuppel I6,` insole I8.^ ahdhody II of our mock Welt III.V

As thus far assembled, the shoe is thereupon re-lasted and the outsole 3| attachedV thereto by a line of tacks 32 which are readily driven thru the sole 3l', body II of the mock welt I0, upper I6 and insole I8, and clinched over against the, lastv bottom, as,` shown. And, again, as in Vthe other formsI described, the shoe is now in readiness for the usual finishing operations.

From the foregoing, it will be apparent that our invention may be readily adapted to various types of McKay shoe constructions, functioning as an, ornamental, seam-filling, andmoistureproof element. The tapered body portion II ideally arranged to ll the, inner space between the lasted upper and the. sole elements, while the. construction of the bead l2 adequately fills the outer seam therebetween and conceais the stitching. Asv shown Figs. 2, 3 and e, the tightening action of the stitches 2l, 2t, and respectively, is sufficient to .flatten out the rib le, thus creating enough pressurev on the fia-nge il so, that it will hug the marginal' edge of the upper lil in moisture-tight association. The resilient, and yielding characteristics or the syn. thetic plastic material are, of ,thev utmostA iinportance in making our beaded mock welt so. useful,v serviceable, ecient, and comfortable to the wearer, and the fact that suchv material is waterproof and may be produced in, any color adds to the allearound value of our product.

While. our beaded mock welt, as above ex plained, is directed for use with footwear of the McKay type of construction, we do not wish to be limited thereby as our invention could well be adapted to other types of shoe construction.
