ATTORNEY United States Patent SHOE CONSTRUCTION INCORPORATING AN UPPER SECURED TO AN UPSTAN DING RllVl FORMED ON THE OUTER SOLE AND WITH AN INTEGRAL HEEL AND SHANK PIECE HICORPORATED WITH THE OUTER SOLE AND LYING BELOW THE RIM THEREOF Jacobus Adrianus Bergmans, Waalwijk, Netherlands Application November 3, 1952, Serial No. 318,410

Claims priority, application Netherlands June 13, 1952 1 Claim. (Cl. 36-12) The present invention broadly relates to the art of shoe manufacturing.

More particularly, this invention relates to a shoe construction in which an outer sole is provided with an uninterrupted turned up or upstanding rim that extends around its periphery and to which the upper is secured.

Still more particularly, this invention relates to such a shoe construction in which the sole is provided with a depression at one end thereof and an integral heel and shank piece is disposed in the depression and surrounded by the turned up rim.

Shoes of this type are known in which the space between the inner surfaces of the turned-up rim of the sole is completely filled with an insole construction and a heel member and thus the supporting surface for the foot lies flush with the upper surface or top of the turned-up rim of the outer sole. If the upper of the shoe is fixed to this rim, the seam connecting the sole construction with the upper lies about at the same level as it does in conventional footwear, namely about at the level of the supporting surface for the foot. It is therefore just as difficult to make footwear of this type properly watertight as in the case With conventional footwear.

Therefore, the present invention has for an object to provide a shoe construction in which the turnedup rim extending around the periphery of the outer sole forms part of the side wall of the shoe and to which is secured an upper in such fashion as to present an attractive appearance.

Consistent with the aforegoing object, the invention provides a shoe that is economical to produce, is of durable construction and is possessed of particularly enhanced flexibility.

It is a further and specific object of this invention to provide a shoe of the aforedescribed type in which the connection between the upper and the turned-up rim is such as to facilitate the obtaining of a watertight connection.

According to the invention the aforegoing objects are realized by constructing an uninterrupted turned-up rim that extends around the periphery of the outer sole so that it projects above the supporting surface for the foot as comprised by the outer sole construction and the built-in integral heel and shank piece, a distance such that the rim forms a part of the side wall of the shoe. In this manner there is obtained a shoe in which the juncture between the sole and the upper, particularly any seams connecting the upper to the rim, extends all around the shoe periphery at a level considerably higher than the supporting surface for the foot. It is theerfore seen that with this construction the juncture between upper and the rim of the outer sole and any seams connecting the upper to the rim lies considerably above the level of such a juncture and seams in conventional shoe constructions whereby the shoe can ice readily be made of waterproof construction. The builtin integral heel and shank piece renders the use of a reinforcement for the intermediate part of the shoe lying between the heel and the front part of the outer sole superfluous and also eliminates the necessity for using an insole, whereby with these measures a good watertight shoe is readily obtained in an extremely economical manner.

As indicated above, the upper is preferably connected to the turned-up rim of the outer sole in such fashion as to provide a watertight and dustproof connection. Therefore, the juncture between the upper and turnedup rim of the outer sole are appropriately glued together and this juncture is covered by a narrow cover strip. The cover strip is sewed to the upper, turned down over the juncture between upper and sole rim and then sewed to the sole rim. Any stitching incorporated in effecting the connection between upper and rim including the connections with the cover strip can be constituted by watertight sewing seams.

It is remarked that footwear with a. turned-up sole rim projecting partially above the foot supporting surface of the sole construction and to which the upper is connected, is known in itself. However, in such known constructions the heel is not built-in but is fixed externally to the heel end of the outer sole, whereby it is necessary to provide an internal reinforcement for the shoe part intermediate the heel and the front part of the outer sole, and also to provide an insole construction in order to obtain durable footwear.

Further and more particular objects will be apparent from the following description taken in connection with the accompanying drawings, and in which:

Figure 1 illustrates in perspective an integral built-in heel and shank piece for use with a shoe sole constructed according to the invention,

Figure 2 is a perspective view of the shoe sole constructed in accordance with the invention, including a turned-up rim extending around the periphery, a depression at one end thereof and diagrammatically denoting the built-in integral heel and shank piece disposed beneath the upper surface of the rim,

Figure 3 is a perspective view illustrating a shoe constructed in accordance with the invention and including an upper connected to the sole construction shown in Figure 2, and

Figure 4 is a cross-sectional view of the front part of a shoe on an enlarged scale clearly illustrating the connection between the turned-up rim of the outer sole and the upper.

In the drawings, the integral heel and shank piece includes the heel portion 1 and a thin tapering extension 2. This thin tapering extension 2 not only forms a shank piece for the shoe but functions as an arch support. In Figure 2 is shown the outer sole which includes a piece denoted at 3 forming the bottom of the front part of the shoe and a depression indicated at 4 which receives the heel member 1 of the integral heel and shank piece. The outer sole is surrounded by 2. turnedup or upstanding rim 5 extends uninterruptedly around the periphery thereof a distance such that it projects above the upper surface of the integral heel and shank piece. Thus the outer sole construction of this invention provides a rim that extends above the foot supporting surfaces of the shoe. The outer sole with its turned-up or upstanding rim can be manufactured by molding the leather on a last having the integral heel and shank piece arranged upon it. It is also possible to utilize a last having an integral heel portion or if desired, the outer sole may be formed with the required turn-up rim or depression with the use of molds or dies. The integral heel or shank piece can be fixed to the surface of the outer sole by gluing and to the surfaces forming the depression 'by gluing. The thus obtained outer sole having a built-in integral heel and shank piece forms the entire lower surface of the shoe so that it is not necessary to utilize insole constructions and separate arch supports. Following the formation of the outer sole with its built-in integral heel and shank piece, the upper 6 is secured to the upstanding rim 5, as is clear in Figures 3 and 4. In securing the upper to the turned-up rim, a narrow cover strip 7 of thin, tough upper leather is stitched along the lower marginal edges of the upper 6 by a row of stitching denoted at 10. The upper portion of the turned-u rim 5 is reduced in thickness either mechanically or by hand. Following this, the upper is arranged on a last in such a manner that the lower portion thereof smoothly joins the reduced part of the turned-up rim 5 of the outer sole in overlapping relation in providing an even juncture 8 between the upper and the rirn. This is a smooth juncture extending all around the periphery of the shoe. 1

The narrow cover strip 7 is then folded down over this juncture and glued to the portion of the turned-up rim beneath the juncture 8. Then rows of stitching 9 and 9' are utilized to secure the parts together. The stitching incorporates strong linen thread and includes an upper row of stitching 9 that secures the upper to the reduced portion of the turned-up rim and a lower row of stitching 9' that secures the cover strip to the rim below the juncture 8. Thus the juncture between the upper and the turned-up rim is completely covered by the cover strip and the upper is secured to the turned-up rim in overlapping relation. 1

Proceeding in this fashion provides a very strong dust and watertight connection between the outer sole and the upper. Due to the position, that is the level at which this connection is effected, the same is subjected to very little wear, the upper row of stitches 9 lies somewhat recessed behind the cover strip so that it is protected and the cover strip protects the juncture between upper and the turned-up rim against damage.

Furthermore, to provide an enhanced waterproof protection the overlapping portion of the upper can be glued to the reduced portion of the upper part of the turned-up rim as indicated by the gluing denoted at 11.

For preventing undue wear at the counter end of the heel, a thin heel lift indicated diagrammatically at 12 may be arranged under the heel. As indicated this heel lift projects slightly beyond the periphery of the heel portion of the moulded outer sole.

A further particularlity of the footwear made according to the invention consists in the fact that the same can be completely constructed without the use of nails.

Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be performed I declare that What I claim is:

A shoe comprising in combination, a sole having an uninterrupted turned up rim extending around its periphery and further having a depression at one end, an integral heel and shank piece disposed in the said depression and surrounded by the turned up rim of the sole, said turned up rim projecting above the level of the heel and shank piece and thus above the foot supporting surface so as to constitute a part of the side wall of the shoe, said rim including a reduced upper portion, an upper of a thickness less than the thickness of the rim and including a lower portion overlying the reduced upper portion of the rim and terminating in a lower edge whereby the overlapped portions of the upper and reduced portion of the rim are of approximately the same thickness as the thickness of the portion of the rim below the reduced upper portion thereof, a narrow cover strip overlying the lower portion of the upper and extending below the lower edge thereof and overlying a portion of the rim below the reduced portion thereof, means connecting the cover strip to the lower portion of the upper only at a level above the lower edge of the upper, stitching connecting the cover strip to the rim at a level below the lower edge of the upper and additional stitching connecting the lower portion of the upper to the reduced upper portion of the rim at a level above the means connecting the cover strip to the lower portion of the upper.
