This application is a division of application Serial No. 743,140 which was filed on October 11th, 1924 and on which a Patent, No. 1,636,677, was granted on July 26th, 1927.
This invention relates to insoles for boots and shoes of the kind provided with sewing lips which are either formed entirely by or merely reinforced with separate strips which are cemented in position, and the invention consists essentially in combining this kind of insolewith a shank piece which covers the rear part of the insole including the entire heelv portion so as to lend rigidity to the same and determine its shape and which is cemented in position.
A cement is used which is sweat as well as waterproof, preferably a solution of celluloid or a celluloid derivative.

Fig. 16, a similar section of the completed sole shown in Fig. 7',
Fig. 17, a similar View of the sole shown rious features of the invention have been applied.
'The insole 1 shown in Fig. 1 is channelled in any well known manner to form a. sewing lip 2, and this lip is reinforced by strips 3 of L-shaped cross-section which, according to the invention, are cemented to the sole 1 and to the lip 2 under pressure by means of a solution of celluloid or of a celluloid derivative. The reinforcement strips may be high enough to allow of being doubled over the stitches 4, as shown in Fig. 3, after the con nection of the insole to the upper. As the "cementing solution renders the connected leather elements practically integral, the channelling of the sole can be obviated by making a separate sewing lipand cementing the latter to the sole which then allows of being very thin. Such an arrangement and several forms of construction of the sewing lip are shown in Figs. 4 to 7. The lip 6 shown in Fig. 5 is composed of a thick leather strip which is slit at one edge to form flaps which are bent aside in opposite directions to form a base whereby the lip can be cemented to the sole 1.' The lip 5 in Fig. 6 is simply'formed out of a strip bent into L- section, and the lip 5 in Fig. 7 is composed of two strips of L-section which are cemented together and to the sole 1.
The reinforcing strip for the sewing lip may be made up of a as shown in Fig. 1.
. In connection with the sewing lips, a shank piece 12, which covers the rear part of the sole including the entire heel portion, is preferably cemented to the insole 1 so as to lend rigidity to the latter and determine its shape. Fig. 8 shows an insole to which both a shank piece and a sewing lip 7 are cemented. The shank piece is also formed with a sewing lip which adjoins the lip 7 as a continuation of the latter. The lip 15 of the shank piece may be formed by channelling as shown in Fig. 9. The shank piece extends from the fore part of the insole right to the back. of the heel where it follows the contours of the latter. At the waist the shank piece is narrowed to form a recess 14 for the reception of the edge of the upper. Before the shank piece-is cemented to the insole, a horseshoe formed metal strip 13 is connected to the same so as to be interposed between it and the insole 1. This metal strip is positioned so that the nails of the heel will be clenched against it and prevented from penetrating the insole 1. The celluloid solution in which the metal strip becomes embedded, binds the leather elements securely together and effectively prevents a relative dislocation of the latter as well as of the metal strip.
The sewing lip of the shank piecemay also be made separately and cemented in posiplurality of short strips tion.
Fig. 13 shows such an arrangement. The edges 16 are sloped for the reception of the lip 17 which in this case may be formed in the same manner as the lip 6 shown in Fig. 5.
Owing to its high adhesive and resistive properties the celluloid cement lends itself admirably for the fashioning of the insole in other respects than those already described. For instance by means of triangular strips cementedto each side of the sole, the latter can be shaped so as to present a concave, comfortable supporting surface to the foot. Thus the sole margin may be set at an angle relative to the middle portion of the sole and supported in this position by means of triangular strips 8 cemented to the sole inside the sewing lips, as shown in Figs. 1 4: and. 16 to 18. These strips .are cemented to the sole after the upper and the welt, if any, have been connected to the same so that the stitches will be covered by the strips and effectively protected from moisture. As an alternative,
the concavity of the tread surface may be produced by cementing triangular strips 10 to the top side. of the. sole, as shown in Fig.
15. In Fig. .10 which shows an insole 9 suitable for sewn, pegged or screwed boots, a suitable division of the strips 10 is indicated. The strips are cemented in position after the attachment of the outer sole, so that the stitches, nails or screws will be covered by to its initial position and cemented by means of the celluloid solution so as to form a per manent protecting cover for thenails.
Fi 22 shows an insole 1 wherein the various Features of the invention are combined.
applied t9 the top of the insole, and the horseshoe formed metal strip is shown at 13. The shank piece 12 is provided with cemented-on sewing lips 17 applied to the sloping surfaces 16, and it is recessed at l lto make room for the edges of the upper. The sewing lip 2 of the insole proper is formed by channelling The dotted lines10 indicate a triangular strip the latter and it is reinforced by strips-3 of I l.;,-shaped cross-section.
The attachment of the sewing lips and the shank piece is effected by means of a presstool capable of fixing the elements in their correct relative position. The press-tool is illustrated in Fi s. 19 to 21. i It consists of a block 18 which is formed with a recess 20 for the reception of the insole and the shank piece, and grooves 19 are made at the bottom of the recess for the reception of the sewing lips. The latter and the shank piece are-first placed in position, whereupon, after the application of the celluloid cement, the
in sole is superposed on the other elements and pressed against the latter by means of a cover In this manner a theoretically correct position of the sewing lips can be ensured so that the attachment of the upper on the sewing machines will present no difiiculty.
The block 18 may be divided in any well known manner into parts which can be relatively adjusted so as to accommodate the tool to insoles of diflerent sizes.
An insole provided in this manner with shank piece and sewing li s secured by means of celluloid cement, will be much more rigid and durable than the channelled soles, while it is equally if not more elastic.
I claim 1. In an insole for boots and shoes the combination with a sewing lip comprising strips which are connected to the insole, of a shank piece which covers the real part of the sole including the entire heel portion and which carries the sewing lips at the waist, the
shank piece as well as its sewing lips being cemented in position. i
2. An insole having the features claimed in claim 1 and in which the edges of the shank piece are sloped for the reception of the sewing lips.
3. An insole according to claim 1 in which the shank piece is made narrower than the sole at the waist so as to form together with the part of the sole which extends beyond it a recess for the reception of the edge of the upper.
4. In an insole for footwear, a sewing lip formed by channelling the sole, a reinforcing lip composed'of a plurality of short,- L-shaped strips cemented to the sole, and a shank piece which covers the rear part of the sole including the entire heel portion and which is cemented in position.
5. The insole structure claimed in claim 1 and a horseshoe formed metal strip interposed between the shank piece and the insole proper so that the nails of the heel will be clenched against it. I
In testimony whereof I have signed my name to this specification.
