'3 Claims. (Ci. are-12 The present invention relates to shoes, sandals and slippers and more particularly to shoe construction providing simplified methods of manufacture.

In the lasting of shoes it is common practice to turn the marginal edges of the uppers over the last, forming a margin on the bottom of the last upon which the soles are mounted either by cement or tacking. This requires considerable skill on the part of the operator and consumes some time in the operation.

In the present method of construction the marginal edge of the uppers is perforated to receive a lacing or cord in such a manner that the edges of the uppers may be tightly drawn around the last for the lasting of the sole to the uppers over the laced edges. While cross lacing may be provided, draw strings may also be used to draw the marginal edges of the uppers tightly over the last. The marginal strip at the base of the uppers may be a part of the upper itself or may be a special strip sewed to the upper surrounding, if desired, the edges of the inner sole or even a portion of the outer sole in vent that the outer sole is covered at the edge. This construction provides an efiicient means of lasting the sole to the uppers, insuring a uniform and neat fit for the uppers over the last and, in addition, providing strength in construction and simplicity and ease in manufacture.

The invention in its fuller details will be more readily understood by a consideration of the embodiments described in the specification below when taken in connection with the drawing illustrating the same in which:

Figure 1 shows a sandal in section to which the invention is applied.

Figure 2 shows a plan view looking at the bottom of the shoe before the sole is applied.

Figure 3 shows a step in construction before the upper is laced, as shown in Figures 1 and 2.

Figure 4 shows a modification of the invention in relatively the same position as indicated in Figure 2.

Figure 5 shows the invention as applied to an open strap sandal, and

Figure 6 shows a further modified construction of a detail.

Referring to Figures 1, 2 and 3 which indicate the shoe upper to which there may be stitched around the lower edge a marginal strip 2 by means of the stitching 3. As indicated in Figures 1 and 3, the two edges are faced and stitched together on the inner side of the shoe and the marginal strip is carried over around the edges of the sole 4 which extends throughout the entire base of the shoe. The marginal strip 2 is preferably perforated with holes 5, 5, 5 etc., which are spaced in the desired manner around the entire peripheral edge of the strip 2. A lacing 6 is threaded through these holes in the manner indicated in Figure 2 commencing from the heel portion 1 (Figure 2) to the toe portion 8. As indicated in Figure 2, this lacing may be cross lacing from side to side of the shoe ending at the toe with'the laces threaded through the last holes on the same side of the shoe instead of being cross laced. This lacing of the marginal strip 2 will draw the edges of the margin tightly over the sole 4 which sole may be an intermediate sole over which a second sole may be cemented in any desired manner. The ends of the thread 5, it may be tied or simply tucked in under the oversole when it is applied to the sandal or the shoe. If desired, as illustrated in Figure 6, a cover or lining may be sewed in over this sole as indicated by the element 9 which may be stitched both to the upper l and the lower attached strip 2. The sole 6 may be of the usual material such as leather, fibre, composition or paper while the composition of the uppers and the marginal strips may also be of similar materials.

The marginal strip 2 may be initially creased at the edges. if desired, although this is not necessary in the present invention where the lacing draws the edges of the strip tightly over the sole or the bottom of the last. The marginal strip may, if desired, be omitted, in which case the perforations are made in the peripheral edges of the upper and it is drawn over the last in the usual manner. When the lacings have once been drawn tightly, no further adjustment is necessary to the upper for lasting the slipper, sandal or shoe.

In the arrangement indicated in Figure 4, the lacing is accomplished in a manner slightly different from that shown in Figures 1 and 2. Here the margin it is looped over and stitched at H providing channels l2 and i3 respectively around the sole and heel portions of the shoe through which the draw strings It and run. These draw strings are drawn and tightened thus drawing the edges I6 and I! of the marginal strip It! tightly over the last or sole of the shoe. The finishing of the sfioe may then be accomplished in the usual manner by cementing the sole of the shoe.

In the arrangement indicated in Figure 5, the system is shown as applied to a strap sandal. In this case the straps II, II, etc. of the sandal at the toe and the loop strap I8 at the heel are perforated at the ends l9, l9, etc., and 20, 20 which ends are bent over the bottom of the sole 24. A lacing 22 is threaded cross-wise or peripherally around the shoe thus drawing the ends of the straps tightly over the sole or over the last if the shoe is, of course, on the last prior to the cementing of the sole.

It will be evident from the description above that the construction in accordance with this invention may be applied to various types of shoes and to various forms of construction as, for instance, shoes in which covered soles are used or those in which the soles may not be covered. While the construction in accordance with the present invention is particularly useful in cementing processes, it may, however be ap plied to other methods of construction, the principal advantage being the holding of the uppers in the proper position while the shoe is being finished and in giving the shoe added strength in that the lacing and draw strings hold the shoe together even after the sole has been applied.

Instead of lacing the entire lower edges of the uppers, parts only may be laced together, particularly those parts essential to form and fit the uppers over the last. For this purpose the ends at the toes and heel may be tacked or cemented and the rest of the edges laced together. Having now described my invention, I claim: 1. In a shoe construction, an upper, a sole cover and a strip stitched together at the lower marginal edge of the upper, a sole contained within said sole cover and said strip, said strip having perforations spaced around the strip and a lace therethrough to draw the edge of the strip over the sole.

2. In a shoe construction, an upper providing a marginal edge about its lower end where the sole is attached, a strip stitched at its edge in face relation about said lower end with the two edges touching each other, said strip having perforations spaced around the same, and cross lacing threaded through said perforations laterally across the shoe, and a sole member over which said lacing is positioned, said stitched portion of said strip and lower end of the upper being drawn inward and lying in face-to-face relation with said sole member.

3. In a shoe construction, an upper providing a marginal edge about the lower end thereof where the sole is attached, a strip positioned in face-to-face relation with the lower marginal edge of the upper, the edge of the strip and the edge of the upper being adjacent one another, a sole member having its periphery extending over the adjacent edges of the strip and upper and through stitching holding the sole member and the edges of the strip and upper together, said strip having perforations therethrough and cross lacing threaded through said perforations laterally across the shoe.
