COMVPOUNIJA INNERSOLE FOR WELT SHOES Filed May 15, 1929 1a: gal

zwzi' Patented Feb. 7, 1933 TES PATENT OFFICE BERCY W. VALENTINE, or Narren, MASSACHUSETTS COMPOIND INNER-SOLE FR WELT SHOES Applica/cien filed May 15,

This invention relates to shoes and the art of shoe making and is particularly concerned with innersoles for Welt shoes. Its ultimate object is Vto provide an'innersole having a 5 leather ply on the side which comes next to the Wearers foot in the completed shoe and is thereby suitable for use in a so-called all leather shoe, which at thesame time can be produced at much less cost than an all leather innersole and has adequate strength and other desirable qualities forthe purposes :of an innersole. have produced a composite sole having a leather Vply extending the full Width of the sole, a filler piece occupying the space on the outer side of the sole Within the stitch-receiving rib thereof, and an originally separate rib element secured first to the filler piece and subsequently, in the course of stitching the inseam, to the leather ply by the stitches of the inseam.

The invention consists in the new innersole having the characteristics above indicated, and others subsequently described, as an article of manufacture or shoe finding, and

also in Vthe characteristics of the innersole as affected and changed by the inseaming. op-

eration and the combination of such inner'sole with the shoe.

Like reference characters designate the same parts Wherever they occur in all the iigures.

There are three elements in my new coniposite innersole, to Wit, a leather ply or body a, a fillerpieee or ply b, and a rib stripe. The leather ply is preferably made of split high grade leather' carrying the grain surface and 6 0 of less thickness than that necessary for an all leather innersole. It is channeled in the flesh side fromfa line Within its edges outward toward the edge forming a flap d Which is turned up to form one element of the stitch- C5 fabric, or inferior leather, or other suitably 75 strong material Which is less' expensive than the leather required for Whole leather innersoles. It is out to anoutline and dimensions conforming to the space on the under side of the' body ply a Within the base of the turned up flap d. Custoinarily the rib of an innersole for Welt shoes terminates at each side of the sole shortof the heelend, as shown in Fig. l, and for such soles the filler pieceispreferably exten-ded to the heel end and given the full Width ofthe sole beyond the termination of the rib.

The rib element c is preferably made of a folded strip of textile fabric located sub- Sammy faust wat the. edges of the suer o piece and attached thereto by one or more seams e, f. The preferred structure of such rib element is that shown in Figs'. 2 and 4.

The fabric of which it is composed is folded lengthwise to form two plies of unequal f Width and both plies are turned over in the same direction to forma base flange at one side only ofthe upstan'ding part, which may be called the ribproper, The stitches of the seam e pass through both p lies and the stitches of the seam pass through the wider one only of the two plies, this construction giving the desirable effect of tapered thickness in the base flange for enabling the rib to be securely united with the filler piece and, more particularly, making it possible to locate the rib proper substantially fiush with the edge of the filler piece.

rlhe filler piece with its attached rib is then placed on the body ply of the sole so that it covers the area within the channel flap al, and is secured by a strong rubber cement, or other suitable adhesive. The rib proper c then lies close to the channel flap and substantially in contact with the inner side thereof, due to the fact that it is placed at the edge of the filler piece and that the latter is cut to the dimensions of the space bounded by the channel flap.

In all essentials the composite sole thus constructed is complete as an article of manufacture ready for incorporation in a shoe. As such it may be made by manufacturers of shoe findings for sale to shoe manufacturers or may be made in the insole departments of shoe factories. If desired, in order to make a still stronger bond between the innersole body and the filler and its rib, a film of cement or the like may be spread between the rib c and the flap d, or these parts may be stitched together, or may be both cemented and stitched; although such additional bond is not essential in the separate innersole in view of the bond created by the inseam of the shoe when the innersole is afterwards united with the upper and welt.

This composite innersole is adapted to the Goodyear method of shoe making and may be combined with other parts of the shoe in the usual way. It is then secured to the shoe upper g and its lining h, and to the welt y' of the shoe by the inseam c, as shown in Fig. 4. The stitches of the inseam pass through the upper leather, lining, channel flap and rib, tying the rib and flap together and thereby additionally securing the filler to the body of the innersole, as well as securing the upper, welt and innersole together. T e excess stock in the rib and edges of the upper is then trimmed off close to the inseam, and the outer sole Z laid on the bottom of the shoe and secured to the welt by the outseam m in the usual way.

The composite innersole of this invention has all the advantages of an all leather innersole and costs -substantially less. It is also less expensive and easier to make than the well known Gem innersole, as it contains less fabric and the filler iece with its attached rib is simpler to ma e and apply than the fabric reinforcement of the Gem type of innersole. It possesses ample strength, for the filler piece itself has substantial strength, the fabric rib is strong and strongly attached to the filler piece, and the flap of the innersole body also has substantial strength and is so disposed in combination with the inseam that it aids in preventing displacement of the filler while holding the body part securely in place within the shoe.

Various departures or changes from the materials, construction and arrangement of parts hereinbefore described may be made without departing from the spirit of the invention and from the protection which I claim. For example, the rib may be combined with the filler piece in the manner shown in Fig. 6, so that its rib portion proper extends across the edge of the filler piece toward the opposite side from that to which its base flange is applied. In this form, the base flange may be made of a width enough less than the width of the channel in the leather body to permit of its entering and lyingl in the channel. The dimensions of the filler piece are made in this ease enough smaller than those of the space bounded by the channel flap to admit the rib between the flap and the filler piece, but they need be only slightly smaller; and the outline of the filler piece is still similar to the outline of the flap. In this case, where the rib is wrapped about the edge of the filler piece, the rib proper is substantially flush with such edge. The modification just described has this advantage, that it utilizes otherwise waste space to receive the base flange of the rib element and does not appreciably increase the thickness of the sole at the edge of the filler piece. The stitches of the inseam may be placed flush with, or even somewhat back from the outer side of the filler piece and the composite rib subsequently trimmed oit nearly or exactly flush with it, enabling the filler piece to fill completely the space between the outer sole and the innersole body within the outline of the inseam rib.

Another variation is shown in Fig. 7 and consists in forming the flap al of the leather body by channeling inward from the edge of the body instead of outward from a line on one face at some distance from the edge. This modification, while inferior to the preferred form, because it leaves less thickness at the margin of the body, is useful and practical nevertheless.

In this composite innersole the entire rib for receiving the stitches of the inseam is formed in part by the channel flap cl and in part by the rib element c, these two elements cooperating to provide a. composite stitch receiving rib.

What I claim and desire to secure by Letters Patent is:

l. A composite innersole consisting of a leather body having an integral flap protruding from one face, a filler piece occupying the space bounded by said flap and adhesively united to the face of the body, and a fabric rib element having a base flange stitched independently to the filler piece and a rib proper portion extending away from the filler piece substantially Hush with the edges thereof and contiguous to the inner side of the flap.

2. An innersole consisting of ,a yleather body having an outturned flap projecting from one side at a distance inward from its edges and a channel in the same side at the base of, and within, the space vbounded by said flap, a substantially rigid, separate filler piece similar in outline to the space bounded by said flap located in said space y.and adliesively attached to the face of the body, and a rib element contiguous to the inner surface of the flap, extending between the same and the edge of the filler piece, and having a base flange occupying said channel and stitched separately to the filler piece.

3. The method of making a composite innersole which comprises channeling a body piece and turning up the flap of said channel on a line within the edge of the body substantially similar to such edge, separately providing a self-sustaining ller piece having outlines and dimensions substantially conforming to the space within said upturned flap, separately stitching a doubled strip of fabric to the marginal portion of said filler piece and turning up the fold of said strip as a rib proper substantially flush with the edge of the filler piece, and placing the filler piece against the innersole body within the space bounded by said flap and with said rib proper extending contiguous to the flap.

In testimony whereof I have aiiixed my signature.
