Specification of Letters Patent.

Application filed December 26, 1911. Serial No. 667,949.

To all whom it may concern Be it known that I, MELVIN L. SEvnnY, a citizen of the United States, and a resident of Arlington Heights, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Means of Attaching Soles and Heels, of Which the following is a specification.

This invention relates to means for reniovably attaching soles and heels to boots andshoes and the like; and it comprises an engaging member for the insole, an engaging member for the outsole, and removable means for fastening saidmembers together; similar means being adapte'dfo'r the heel also.

In thev drawings forming part of this specification, Figure 1 'is an under view of' a boot or shoe, showin the engaging members or plates fastene' to the same. Fig. 2 is a side view of a shoe having its outsole and its heel attached thereto by means embodying the invention, parts thereof being represented as broken away. Fig. 3 is a cross section on an enlargedscale of parts of the engaging membersand the removable means. "Fig. 3 is a sectional View of a line of attaching devices or bridges. Fig. 4 is a perspective view of said bridges. Fi 5 is an'under view of parts o'f-a shoe and engaging members. Fig. 6 is a side view of two engaging members or plates, illustrating the toe-attaching devices. Fig. 7 is a plan view of part of'a modified form of the engaging members or plates. Fig. 8 is a like View of'one of said plates alone. Fig. 9 is a plan view showing another modified form of said plates.

Referring first to Fig. 1, the reference numeral 1 designates the engaging member or plate fastened to the outer surface of the insole of'a boot or shoe, said plate being shown as more or less skeletonized for the sake of lightness and increased flexibility.

This plate is first positioned on theinsole 4 as practicable, is formed a line of engaging elements 5' struck up from the plane of said plate, and from a likeplate 6 fastened to the outsole 7 are similarlines of engaging elements struck up from its plane, the elements of each plate extending into the plane of the other plate and so intermeshing and disposed as to permit a wire 10 to be thrust through each line of intermeshin elements. As shown in Figs. 3 and l, sai engaging elements are in the form of arches or bridges'o, those rising from the surface of one plate nesting into the concavities of'the corresponding bridges of the other plate. I use the term' bridge in contradistinction to an angular projection free at one end. In means for attaching soles and heels, it is imperative that the devices be at once strong and invisible, or at all events so nearly so as not to injure the appearance of the shoe. If angles were used, the necessary strength would require that they be so large as to be prohibitive in many cases of finer grades of shoes, because dependence would have to be had on the resistance of the metal to flexurc. By using eyelets or bridges which are fas tened at both ends, the strength is derived from the tensile strength of the metal, and therefore the construction can be so small and neat as readily to be concealed. This lightness of construction can still further be made use of by having. the bridges distributed near to and preferably in substan tial parallelism with the edges of the shoe, thus giving the requisite pressure upon the edges without the use of stiff and heavy plates. The wires 10 are introduced longitudinally through said bridges, and are made to pass freely from bridge to bridge without meeting the abutments of the latter at curves and so refusing to move farther, by tapering the bridges as indicated in Fig 3, so that the diameter the wire is entering is always larger than that from which the wire is emerging. Consequently, such small diameter of each bridge guides the wire-end easily into the large diameter of the adjacent bridge, and hence assures no stop to the wires travel until its complete introduction. This tapering or conical formation of the bridges performs another important function. that of giving the plates a strong but resilient'connection. One end of each bridge being thus larger than the diameter of the wire 10. while the other end is more closely fitted thereto, there is a considerable distance along the wire between the points where it is closely engaged by the bridges of one plate and by the bridges of the other plate. In other words, as illustrated in Fig. 3", the contacting semi-circle of a bridge at one side of the wire is at a dis tance from the contacting semicircle of each adjacent bridge at the other side of the wire. Consequently, by .forcing the two plates apart, the wire must yield until it meets the larger diameters of the bridges, and is brought into a serpentine conformation, from which its resilience causes it to recover when the plates are released. By suitably limiting the heights of the bridges, the wires 10 can be forced to acquire such serpentine conformation as they are pushed into place, thus causing the plates to have a resilient pressure together. I may use two separate wires 10, as shown for the outsole in Fig. 1, or a single wire united by an in termediate section, as shown for the heel, and described farther on; but in each case I prefer to lock the wires in place by some suitable means, as by an elbow 11 ada ted to be engaged by a spur l8 struck up rom the plate 1. As it is hardly possible to force the wire or wires 10 about too pronounced a curve, I terminate the bridges 5 at the toe of the shoe, as shown in Fig. 1, and provide other attaching means thereat. This consists preferably of a slit 1 1 in the toe of one plate, as 1, and a fin 15 at the toe of the other plate 6, as indicated in Fig. 6; said fin being adapted to be inserted within said slit before the body of the plate 6 is brought up to engage its bridges with those of the other plate. In substantially the same manner as the plate 1, the plate 16 is pegged or otherwise fastened to the heel-end 17 of the insole, as shown in Fig. 1, and a corresponding plate is stitched or otherwise fastened to the heel 20, and said plates secured together by a wire 21 thrust through the two lines of bridges 5 projecting from said plates. Here I prefer to use a single wire, "with an intermediate section 22 adapted to be engaged by a spur 23 struck up from the edge of said plate 16. The extremities of said wire may be arranged to be brought so near together, as shown in said drawing, that there is no need for the slit and fin 14, 15 above described.

It is evident that all that is necessary to do in order to remove a worn outsole or heel, is to withdraw their wires 10 or 21; first disengaging their parts 11 and 22 from the respective spurs 18 and 23. Then, in the same way as already described, fresh outsoles and heels can be applied; a supply of the latter being kept on hand, each 'with its plates permanently fastened thereto.

As shown in Fig. 5, the rear ends of the outsoles may be given an additional securing device, as the screws 13, but this is ordinarily unnecessary.

In the modification of my invention illustrated in Figs. 7 and 8, each plate is formed with openings 21 through which the bridges 5 of the associated plate can protrude.- One of said plates, that shown in Fig. 8, is 'entirely fiat, the other plate alone having the bridges 5. The main advantage of this is that but a single thickness of the metal overlies the wire 10, instead of the two thicknesses shown in Fig. 4. Another advanta e is that such openings may be made su ciently larger than the bridges to allow a slight play between the latter and the edges of said openings.

In Fig. 9. which is a fragmentary view similar to Fig. 1, I show a modified form of the device of Fig. 1. In this arran ement the bridges are separated by roun holes instead of slits as in Fig. 1 so that the bridges are more widely spaced apart. The bridges are otherwise identical and the wire is inserted in the same manner. The wide spacing of thebridges contributes slightly to the resiliency of the connection.

To insure the register of each member of a pair of associated plates, I usually indent the same at one or more points, as at 28 in Figs. 1 and 3, in order that, the projection from one plate entering the recess of the other, assurance will be thereby given that the bridges of the two plates will accurately register. As shown in Fig. 1, the plates may be formed with slits 29 cutting through from the bridges 5 to the outer edge of the plate, in order to give the same increased flexibility.

That I claim as my invention and for which I desire Letters Patent is as follows, to wit:

1. A fastening for the soles and heels of shoes and the like, comprising two separable coacting members, each having projections reaching into the plane of the other member, and a flexibly resilient elongated device engaging said projections and binding said members together, said projections and de' vice being constructed to permit the latter to be pressed longitudinally into its engagement with the projections and to be put into transverse strain thereby.
