Patented pr. 27, 1943 UNITED STATES ATENT OFFICE 1 Claim.
This invention relates to improvements in shoes of the type wherein the insole is marginally slotted at spaced intervals to receive a plurality of marginal prongs formed integrally with the upper structure at spaced intervals and has for its general object to provide a shoe of this type which will accurately fit the foot and which will exhibit a neat and close-fitting joint where the upper structure and insole meet each other. Other objects and advantages of my invention will appear as the description proceeds.
In the drawing:
Fig. 1 is a side view showing the upper structure assembled to the insole and prior to underturning and cementing down the prongs of the upper structure against the under face of the insole.
Fig. 2 is a cross section through the assembly of Fig. 1.
Fig. 3 is a view similar to Fig. 2 but showing the projecting prongs of the upper structure as having been turned inwardly and cemented down to the underface of the insole.
Fig. 4 is a side elevation of a completed shoe.
Referring to Fig. 4, the shoe therein illustrated comprises an outsole 2i), heel 2 I, insole 22, and an upper structure of conventional design including a vamp 23 and a back 23a.
As shown, the vamp 23 comprises three cross straps 24, 25, and 26 and a slotted toe strap 21 through the slots of which said cross straps are interlaced, and the back 23a comprises a curved quarter 28 with ankle strap 29 and buckle piece 30 secured to the sides thereof.
The insole 22 has adjacent its marginal edge a plurality of spaced'elongated pairs of slots 36' cut therein, with intervening webs or bridges 35 between said slots. These bridges or webs 35 of the insole serve as stops to limit the penetration of the prongs 31 at the ends of the upper parts 24 to 28 inclusive through the slots 36' of the insole, and also confirm the pitch of the vamp and quarter so as to insure proper tting of the shoe to the last and the foot when I assemble the upper structure and insole, the prongs 31 being drawn through the slots 36 of the insole until the webs 31' separating said prongs abut against the webs or bridges 35 separating related pairs of slots 36'.
I next apply a coating of cement 39 to the inner faces of the prongs and allow it to dry, after which the prongs are turned inwardly and cemented down to the underface of the insole (Fig. 3). It will be noted that the pairs of prongs 31 are of a width to snugly t within related pairs of slots 36 and of a length to extend through said slots and to be folded against and anchored to the bottom surface of the insole when the in- Y sole and upper structure are assembled to each other. It will further be noted that the webs 31 constituting the closed ends of the notches extend as straight edges which are substantially equal in length to the distances between the slots of their related slot pairs so that when the prongs are drawn tautly through the slots said straight edges are disposed at such angles to the transverse axes of the straps as to atly abut the upper surface of the insole at the line of contact between said straight edges and the insole, whereby to correctly position the upper structure with reference to the insole, as well as assisting to firmly lock the upper structure against longitudinal shifting movements relative to the insole.
The structure is now ready to receive the outsole `and heel. In attaching these parts, a last is rst inserted in the structure and a coating of cement 40 is applied to the outer faces of the inturned prongs 31 and to the underface of the insole to hold the outsole and heel. The last is then withdrawn resulting in a completed shoe (Fig. 4).
If the insole 22 is of the platform type, I cement as at 4I to the upper face thereof a sheet 42 of decorative material, vas leather, cloth, or the like, drawing the same around the marginal edge of the insole as at 43 and cementing it down to the underface of the insole as at 44. This decorative cover is applied to the insole before the slots 36 are cut in the insole, and hence is likewise slotted through by the same tool which cuts the slots 3S in the insole.
Although I have described and shown a shoe of the sandal type, it will be understood that such disclosure is purely illustrative and in no way limiting and that shoes of practically any style and design may be produced by my method.
What I therefore claim and desire to secure by Letters Patent is:
A shoe of the sandal type, comprising an insole having adjacent its marginal edge a plurality of spaced elongated pairs of slots, the slots of each slot pair being spaced apart from one another a substantial distance, and an upper structure cornprising a series of independent transversely extending straps, each strap having its marginal edge centrallyrnotched to provide pairs of spaced prongs, said pairs of prongs being of a width to snugly t within related pairs of slots and of a length to extend through said slots and to be folded against and anchored to the bottom surface of the insole when the insole and upper structure are assembled to eachother, the closed ends of said notches extending as straight edges which are substantially equal in length to the distances between the slots of their related slot pairs and which When the several pairs of prongs are drawn tautly through the several related pairs of slots are disposed at such angles to the transverse axes of the straps as to flatly abut the upper surface of the insole at the line of contact between said straight edges and the insole, whereby to correctly position the upper structure with reference to the insole.
