PATENT OFFICE PANY, OF FARIBAULT,

MINNESOTA, A CORPORATION OF MINNESOTA CROSS STRAP SANDAL Application filed February 17, 1932. Serial No. 598,501.

This invention relates to the construction of cross strap sandals and similar shoes, wherein straps of leather or other analogous material are applied to the sole of the shoe tion consists in the novel as for extension from one side of the shoe to the other.

It is the main object of the presentinvention to provide a novel and improved cross strap sandal construction whereby the straps of the sandal may be attached to the sole of the shoe, without causing the sole to hump'up v at points where the ends of the straps are attached thereto. I f

A further object is to provide such a sandal wherein the ends of the cross straps will lie flush with the insole to produce a comfort able and neat appearing sandal and a sandal wherein the straps are securely anchored in position.

To these ends, generally stated, the invenparts and novel combinations of parts and in thenovel manuwill appear after in the claims and described novel steps in the hereinafter defined in the following specification, made in connection with the accompanying drawing, wherein like reference facturing processes and manufacturing processes characters" refer tothe sameor similar parts through the various views, and, in which, v .Fig. 1' is aplan view of a complete sandal embodying the present invention;

Referring first to that embodiment of the invention illustrated in Figs. 1, 2, 3, 4 and 5, there is shown a cross strap sandal including an insole 9, cross straps 10, stays 11, outer sole 12, welt 13, quarter 14, ankle strap 15 and buckle 16. The insole 9 is rabbeted downwardly from its upper surface adjacent its peripheral edge to form a rabbeted portion 9 Four notches 17'are cut inwardly from the peripheral edge of the insole through the rabbeted portion 9a and these notches are preferably in substantially opposing relation in pairs at the two sides of the insole. The peripheral edge of the insole 9 adjacent the beveled surfaces 9?), best 9 has been rabbeted, notched and beveled as described, stays 11 are glued or otherwise se- Icured to the bottom of the insole and these stays, as initially applied, have projecting end portions which extend outwardly across the notches 17. The cross straps 10 are applied in crossed relation as shown in Fig. 1,-

and adjacent their ends the cross straps are into engagement with the beveled surfaces 912 and the end portions of the cross straps are bent outwardly from the beveled surfaces 9 so that these end portions form outwardly projecting tongues 10a. which fill the notches 17 and lie substantially flush with of the insole. The cross straps 10 are secured to the stay's 11 and to the insole 9 by the lines of stitching 18, which run from adjacent the forward portion of the insole through the insole, thence across tlie forward stay 11 to secure the forward ends of the straps 10 tothe forward stay, Fig. 5, but illusthence rearwardly of the insole across the 55 21. At spaced points along the sides of the the stitching 18 pulls the straps tightly against the beveled surfaces 9?). After the stitching 18 is in place, the outer end portions of the stays 11 are inwardly bent to the position shown in Fig. 4:. A welt 18 is now applied over the rabbeted portion 9a of the insole and over the tongues 10a, whereupon the outer sole 12 is applied against the insole 9 and the outer sole is preferably cemented to the insole 9 and is also secured in place by means of stitching, or the like 19. This stitching 19 runs through the welt'13, the rabbeted portion 9a of the insole, the tongues 10a of the cross straps and the outer sole 12. Thequarter 14, ankle strap '15 and buckle 16 form no part of the invention and may be applied in any common manner during the construction of the sandal.

With the sandal construction described, the cross straps 10 are secured by the stitching 18 not only to the stays 11, but also to the insole9. The cross straps are also secured to the insole 9, outer sole 12, and welt 13 by means of thestitching 19. The cross straps will thus be anchored firmly in place, so that they cannot readily be loosened from the sole of the sandal. Due to the fact that the outturned tongues 10a of the cross straps are fitted within notches 17 of the insole, the tongues give no added thickness to the sole of the sandal at their point of attachment thereto and as a result, there is no tendency for the sandal to hump, bulge or bow up atthese points. The insole maintains a smooth, even contour at all points.

In Fig. 6, there is illustrated a laminated insole 20 formedof two pieces of leather 20a and 20b glued or otherwise secured together to. form an insole shaped identically the same and used identically the same as is-the insole 9. The laminated insole 20 is less expensive to make, in as much as thin pieces of leather can be substituted for the thicker piece of leather forming the insole 9.

In Figs. 7 and 8, portions of a sandal are illustrated including insole 21, cross strap'22, outer sole 23 and welt, 24-. In this sandal, stays corresponding in nature to the stays 11 are eliminated. In constructing this sandal,

illustrated in Figs. 7 and 8, the insole '21 is rabbeted downwardly from its upper surface adjacent its edge. in the same manner as was the insole 9 to form the rabbeted portion 21a. Notches corresponding to the notches 17are, however, not immediately cut in the insole insole 21 where the end portions of the cross straps 10 are to fit, the insole 21 is inwardly channeled to form channels 21b of the same length as the width of the cross straps and these channels are cut inwardly from the i edge-0f the insole 21 immediately above the juncture of the rabbeted portion 21a with the body of the insole. The cross straps 22 are positioned, as shown in-Fig. 7, so that the cross straps adjacent their ends lie against the edge of the insole 21 immediately above the channels 21 and also so that the cross straps are partly received within the channels 21. The cross straps are stitched to the insole by means of stitching 25 running diagonally downwardly and inwardly from the outer sides of the cross straps 22 immediately outwardly from the channels 21?), through the channels to the bottom surface of the insole 21. After the stitching 25 is in place, as shown in Fig. 7, the rabbeted portion of the insole immediately below the channels 21?) is trimmed to form notches 26 corresponding in function to the notches 17 of the first sandal construction described. In trimming the rabbeted portion 21a of the insole below the stitching 215, the insole is diagonally cut inwardly and downwardly .to form beveled surfaces 210 corresponding to the beveled surfaces 9?) of the insole 9. From the points where the cross straps 22 are secured to the insole by the stitching 25, the cross straps are carried downwardly to substantially fill the notches 26 and the end portions of the cross straps are bent outwardly to form tongues 22a, as best shown in Fig. 8. \Velt 24 is placed over the rabbeted portion 21a of the insole and over the tongues 25a of the cross straps and outer sole 23 is secured in place against the insole 21 by means of stitching or the like 27," running through welt 24, rabbeted portion 21a of the insole, tongues 25a of the cross straps and outer sole 23.

It will be seen that the sandal construction illustrated in F igs. 7 and 8 prevents humping, bulging or bowing of the sole of the sandal at the points where the cross straps 22- are attached to the sole in the same manner as in the previously described construction. It Will also be seen that the necessity for use of stays, such as the stays 11 is eliminated in the construction shown in Figs. 7 and 8. Cross straps 22 are securely anchored in place and the sandal will present a neat and attractive appearance.

It will, of course, be understood that va rious changes may be made in the form, details, arrangement and proportions of the various parts and in the various steps in the process of manufacture of the sandals illustrated without departing from the scope of the present invention. Alhough the invention has been described and illustrated as being applicable for use in securing the cross straps of sandals, to the soles of the sandals, it will be understood that any straps, strips or the like composed of leather or analogous material, may be attached to the soles of shoes in the manner specified. The invention is, therefore, not confined to cross strap sandals alone. 1

As used inthe claims, the words cross strap sandal are open toa broad enough interpretation 'to cover any type of shoe wherein straps or strips of leather or analogous material are attached to the soles of shoes It should be clearly understood that the invention is not limited to the construction wherein cross straps are extended across the vamp of the shoe. Straps may be applied to the sole at any point along the edge of the same to form a shoe embodying the invention. For example, it is contemplated in place of the usual quarter 14, straps may be applied to the sole in substitution for the quarter. I
