1 Claim.

This invention relates to improvements in sandals and h-asfor its object to provide a lightweight strap sandal of simple and inexpensive construction and one which is comfortable to wear and is also of neat and attractive appearance.

With this object in view, the invention resides in the features of sandal construction hereinafter described and claimed.

The invention will be explained with reference to the accompanying drawing,` in which Fig. l is a plan view of the upper or foot side of the sole of my improved sandal;

Fig. 2 is a perspective view of the sole showing the lower or tread side thereof as it appears after the sole has been'channeled, the channel lips have been raised, and the strap-receiving slots have been formed;

Fig. 3 is a fragmentary cross-sectional View of my improved sandal in process of manufacture;

Fig. 4 is a perspective View of the completed sandal; I

Fig. 5 is a cross-sectional view of the forepart of the sandal;

Fig. 6 is a detailed cross-sectional view of a modification of the construction illustrated in Figs. 4 and 5;

Fig. 7 is a detailed cross-sectional view illustrating a further modified construction; and

Fig. 8 is a fragmentary perspective view illustrating a still further modiiied construction.

In one embodiment of my invention, as illustrated in the drawing, my improved sandal comprises an upper lll, a single sole I 2, and a heel I 4. The upper is composed of strap-like members, comprising a plurality of forepart straps I6 to which is secured an instep strap I8 and two heel straps 28 which are formed as integral parts of an ankle strap 22. The lower portions of the forepart straps I6 and the heel straps 20 extend into marginal openings or slots 24 (Figs. 1 and 2) `in the sole l2 and are iirmly sceured in place within the slots by means of stitches 26 (Fig. 5) which extend from the edge of the sole inwardly through the straps and into an inner marginal channel 28 which is formed in the outer or lower side of the sole. As shown in Fig. 2,.the channel 28 forms a channel flap 36, the channel and the channel ap extending entirely around the sole, and the stitches 26 constitute portions of a line of stitching 32 (Fig. 4) which also extends entirely around the sole. Preferably the outer portions of the stitches are received in a stitch groove 34 (Figs. 2 and 3) so that they lie substantially ush with the adjacent surfaces of the sole edge. A's best shown in Fig. 5, the sole is also provided with an outer channel or edge slit 36 which is cut inwardly from thesole edge Yso as to form a flap or leaf 38 which serves to cover and entirely conceal from view the edges at the lower ends of the straps.

In making the above-described sandal the sole I2 is preferably rst channeled at or adjacent to theside which is to constitute the lower or tread surface of the sole to form the inner and xouter channels 36 and 28 and the inner and outer channel iiaps or lips 38 and 38, respectively, and the sole edge above the flap or leaf 38 is grooved to provide the stitch groove 34. The channelflaps 36 and 38 are then raised substantially to upright positions, as shown in Fig. 2, after which the reduced marginal portion or leaf 48 of the sole (which is formed by the outer channeling or edge slitting operation and which extends outwardly beyond the raised channel nap) is perforated or punched to` provide the strap-receiving slots 24, the latter extending entirely through the reduced marginal sole portion 40 and being shaped to correspond to the cross-sectional contours of the straps which they are to receive s0 that the strap ends will nt tightly within the slots. The straps I6 and 28 may be cut to the exact lengths required and their end portions merely inserted in the slots until the end edges of the straps are substantially flush with the lower surface of the reduced sole portion 46. Preferably, however, the straps are cut somewhat longer than necessary to provide the proper girth measurements to adapt the sandal to t the foot and in applying the `straps they are threaded through the slots and their end portions are caused to protrude more or less beyond the lower side of the sole margin 4U, as indicated in Fig. 3.'

Thereafter a last 42 is inserted in the shoe, the

straps are individually tightened or tensioned, over the last as by the use of a pair of lasting pliers 44 and, while the straps remain in tightened or last conforming condition, they are secured to the sole by means of stitches 'or other y fastenings extending from the sole edge into the channel. After the straps have thus been secured i in place by the fastenings, the surplus strap .material which extends beyond the lower side of the sole is trimmed, for example, by means of a hand trimming knife, such as the knife 46 indicated by dotted lines in Fig. 3, thus making the ends of the straps flush with the lower side of the marginal sole portion 40. Finally, the inner and outer channels 28 and 36 are closed by cementing down the channel flaps 30 and 38 so that the inner flap 30 covers and conceals the inner portions of the 24 are located. The loops or bights are spaced so that one or more, and preferably at least two, will extend through the end portion of each strap and serve to secure the strap to the sole.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

turned lower portions to detract from the appearx ance of the shoe or to causediscomfort to the foot. Moreover, the straps are rmly secured in place by means of the stitches and, as indicated in Fig. 4, if a line of stitching is provided which extends entirely around the sole, the stitches in addition to securing the straps to the sole provide an attractive and ornamental finish for the sole edge.

Instead of employing stitches for holding the straps in place, other fastenings, such as the pegs or pins 5D (Fig. 7) may be used, the pegs or pins being driven inwardly from the sole edge so that they extend through the straps and into the body Y portion of the sole at the inner sides of the straps. If such fastenings are employed, it is unnecessary to form an inner channel in the sole, although it is preferred to form an outer channel so as to provide a channel flap for covering the lower ends of the straps.

As illustrated in Fig. 8, a seam of fairstitching 52 may be sewn along the edge of the sole, the seam comprising loops or bights of thread 54 which extend inwardly beyond where the slots In an open-shank strap sandal, va single sole having a deep inner marginal channel and an edge slit forming respectively a thick inner marginal flap and a thin outer marginal ap each at the tread side of the sole, said sole having in that portion of each lateral margin of its forepart which is above said edge slit a plurality of narrow slots extending lengthwise of the sole edge and disposed in spaced relation to one another, an upper comprising a plurality of spaced straps each having one end portion extending through oneof the slots in one of said lateral marginal sole portions and having its oppositeV endY extending through one of the` slots in the other of said lateral vmarginal sole portions and all of said straps having their end faces abutting and covered by said outer ap, and a continuous line ofv stitching extending entirely -around the sole and comprising stitches all of which extend from the base oflsaid inner channel to the edge of the sole margin andhave their inner portions concealed by said inner flap, some of said stitches extending through said straps and securing them to the sole and the remaining stitches being clear of said straps.
