adaptation of the parts as will be more fully hereinafter pointe out.
It frequently happens that a person has a foot of such shape that it does not accurately fit within a shoe of standard form and in order to insure the greatest amount of comfort to the wearer, the sole of the shoe should be built up or depressed at certain places.
.' It also happens with almost every wearer of' cloth, or rubber.
shoes that there exists a tendency to turn certain portions of the foot in or out of the proper line in walking and the result is that the sole of the shoe receives greater wear at some places than at others.
The present invention aims to provide a means which will correct such tendencies to incorrect walking, and which is readily adaptable to the various needs or peculiarities of individuals. This object, and others which will hereinafter appear, areaccom plished by the construction illustrated in the accompanying drawing, which represents what is at present regarded as the best embodiment of the several importantfeatures of the present invention.
In such-drawings, Figure 1 is a top plan view of an inner sole embodying my several improvements, indicating in dotted lines the positionsof inserts or filling members. Fig. 2 is a bottom plan view of the same. Fig. 3 is an edge 'view thereof. Fig. 4 is a transverse section on the plane of the line 44 in Fig. 1. Fig. 5 is a transverse section on the plane of the line 5-5 in Fig. 1. Fig. 6 is a similar section on the plane of the line 6 -6 in Fig. 1. Figs. 7,8 and 9 are erspective views of the inserts or filling mem ers shown in the other figures and Fig. 10 is'a vertical 4 central section through a low cut shoe inside of which one of my improved inner soles has been placed.
The inner sole, in the form herein illustrated, comprises an upper layer 10 and a lower layer 30, each of which is made of some suitable soft fabric, as thin leather,
In the form which I prefilling members or inserts, and by -those persons whose walk is normal or prgper.
fer, the lower layer is made of thin leather,
and the upper layer is made of two superimposed materials, one (as 11) of soft elastic character, for example sponge rubber, and the u permost 12 of soft, smooth character, as ki or paper. The lower layer 20 and the intermediate layer 11, in the form herein shown, are stitched together. The stitching is arranged to provide between them a series of separated pockets (as 40, and 60) having open marginal edges, adapted to receive removable inserts o'r filling members 41, -12 and 43, as hereinafter more particularly described, whereby the insole may be built up at one or more places to give to the foot sup- .port at a place or places which the peculiarity of the individual wearer may make necessary in order to correct a tendency to improper walk and prevent unequal wear on the sides of the sole or heel. Attention however is here called to the fact that the relation of the parts in the form herein shown is such that the layers lie smoothly one upon the other when said inserts or filling members are omitted or removed, and the insole is, therefore, adapted to be Worn with comfort, without an insert or filling member, by one whose needs do not call for such insert or filling.
member. By providing said j insole with open pockets adapted to receive removable so arranging said pockets that an insert may be placed at any one or more of the places which the different peculiarities of different individuals make necessary, the range of usefulness of the device is widely extended,.and in fact, it may be made to answer every re uirement of all individuals, those whose wa k is such' that unless corrected they run down the heel, or one side of the sole more than another, without restriction as to which sixtie the extra Wear may'be on, as well aslto Moreover, the adjustmentto the'nee ,s of an individual user, may be instanta made by any person, requiring no skill for the purpose.
- Upon reference to the drawings, it will be seen that the pocket 40 is arranged at the ball of the foot portion of the insole, and is produced by securing the layers together by lines of stitches 30' and 31 which con.- verge toward each other from opposite sides of the insole, and by lines of stitches 32 and 32 which converge similarly toward each otherfrom opposite sides of the insole.
' usly tools or The relation of these stitches, therefore, is such as to provide a pocket which narrows from each marginal edge-of the insole toward the longitudinalcenter of the insole. Thus,
in effect, two, or a pair of wedge-shaped pockets 4O areformed, each open along a contiguous marginal edge of the insole, whereby a correspondingly wedge-shaped insert or filling member, as 41, may be inserted thereinto from either side of the insole and will be properly held in position by the side walls of the pocket. L
The pocket 50 is arran ed under the instep and is similarly boiin ed at one end by rows of stitches 33 and 34 which converge toward each other from the open mar inal edges of the insole; and at the other en by similar converging rows of stitches 36 and 39: thus a o forming, in efiect, under the instep or arch of the foot, two wed e shaped pockets, either of which is adapte to receive a removable correspondingly wedge-shaped insert or filling member, as 42.
The pocket is shown as arranged under the heel and is formed by the stitches 37 and 38 which convergefrom the lateral marginal edges of the insole, which edges together with the back ofthe insole are non-stitched. The heel can thus be built up at any side orplace by an insert or filling member, such as 43,
It will be observed that the two pockets- 40, 40 open into each other at about the lon-v gitudinal center of the insole, and that this is true also of the other pairs of pockets. The filling members when inserted into their respective pockets, that is, from either side of the insole, will preferably extend from the marginal edge of the insole across the longitudinal center of the insole and hence will extend partway into the other pocket. While it is preferable to have different filling members for the several pockets 40,. 50 and 60, yet it will not be a departure from the spirit of the invention, or the scope of the sub- %oined claims, to use the same filling member or the several ockets,if such be capable of. serving a usefu purpose in the several places at which such pockets are located.
It will not be imagined that the necessities of any particular wearer will require the use of insertsor fillin members at more than one place at a'time, ut it will be observed that as herein embodied, the insole has provision whereby it is adaptable to any peculiarity. For example, if the wearer has a tendency to throw his ri ht foot forward and wear out the sole of hiss oe at its outside front edge, and
by the strain thusproduced upon the foot cause callousvor corns to develop by inserting the insert or filling member 41 inthe ocket from the corresponding side of the inso e, the
foot of the wearer is thrown toward'the other side, the pressure upon the skin relieved and the corn or callous soon caused to disappear.
'sole illustrated Similarly if the tendency is such that the sole has greater wear imposed jon itslinside front edge, it can'be corrected by placing the insert or' filling member in the side of said pocket 40 opposite to that hereinbefore mentioned. Again, if the wearer of a shoe finds that the arch of the foot needs an extra support, the
insert 42 may be placed in the pocket 50, provided for that purpose, and at either side thereof, thus furnishing the support required. In a similar manner, the wedge 43 may be inserted in the pocket 60 at the heel of theinner sole, from either side thereof. The location of these pockets in the forms of inner erein are merely suggestive. It is "obvious that by varying the position of the stitches employed to unite the lower and intermediate layers of the sole, pockets may be formed at any desired place along the edge of the sole for the reception of an appropriate insert or filling member, and while I prefer the form herein illustrated, yet it is not to be understood that the invention in all respects is restricted thereto.
The inserts or filling members 41, 42 and 43 are not only wedge-shaped by reason of having converging lateral sides, but, as herein shown, their top and bottom surfaces also relatively approach each-other towardthe inner end; that is to say, they are suitably so formed as to be thinner as well as narrower at their inner than at their outer ends. In use, each will preferably extend to or slightly beyond the longitudinal center of the inner sole. These inserts or filling members are preferably made of soft rubber, felt, cork, or somesimilar soft elastic material. They also preferably are of no great thickness whereby, in connection with their removability from the pockets, the layers of the insole may be approximately of the same size and thus lie smoothly upon each other when the inserts or filling members are removed; thus adaptinsole for use without theinserts,
