2' Claims. 1

'Ihisv invention relates to shoes of. the platform type and to a novel method of making the same.

In accordance with thisV invention, I cover the platform sole with a covering made in two se'ctions, viz., a forepart section and la heel section, which are overlapped upon one another in the region -of the heel breast, or' in case a wedge is used, at a slightly forward position toward ball.

In the forepart area of my shoe, I use an insole which has a stitch-receiving lip sewed around its margin or channeled as close to the edge of the insole as is possible without having the stitches pull through. This not only enables me to neatly stitch the forepart section of theV platform cover to the insole lip and upper structure by a single row of stitching, but to use for this stitching step a conventional welt sewing machine, or machines especially adapted for this type of work, such as the Puritan or Union lock-stitch sewing machines.

When so stitched, the forepart section ofthe platform cover takes the place of the welt used in the ordinary welt shoe, after the. unstitched portion of said cover section has been pulled down tightly over and cemented vto the outer-edge of the platform sole and iirmly fastened against. the bottom face of said sole, as by cementing.

In the heel area, of my shoe, the heel section of the platform cover is drawn around the outer edge of the platform sole and rmly fastened against both the top and bottom faces of said platform sole, using conventional heel seat lasting equipment, either hand or machine method.

Thus, I provide a platform shoe of extremely neat and attractive appearance and excellent wearing qualities which can be made on standard equipment at minimum cost.

In the accompanying drawing wherein I have shown a preferred embodiment of my invention:

Figure 1 is a side elevation of a shoe made in accordance with my method, and

Figures 2 and 3 are enlarged cross-sections on the lines 2 2 and 3-3 respectively, of Figure 1.

The upper structure of my shoe is conventional, comprising a vamp I0, quarters II, lining I2, counter I3, and cushion heel pad I4.

In the forepart of my shoe I place an insole I5 which may or may not have Gem cloth or its equivalent I@ cemented to the under face thereof. Stitched at I8 to the insole or channeled as closely as safely possible to the margin thereof is a stitch-receiving lipor rib I'I.

In the bottom of the shoe I place conventional filler material I3 and a platform sole 20.

Platform 26 is covered by a sectional cover or wrapper, of leather or any other suitable material, consisting of a, forepart section 2l and a heel section 2. Section 2`I is applied as a continuous strip beginning at the point marked 22 iin Figure 1 and extending around the forepart of the platform sole to a point (not shown) approximately opposite point Z2, and section 21 is likewise applied'fa's fa continuous strip extending around the heel part of the platform sole and overlapped bysection 2'I in the region of the heel breast.

Cover section 2| iszstitched near its Vupper edge as at' 23 to the. `upper and lip I'I on any Icnnventional .sewing machine. The free portion of the cover is drawn downwardly around the outer edge of the platform and bent inwardly and fastened. against; the bottom face of the platform asat 211.

In the heel .region of the shoe, the quarters II, lining I2, and counter I3 are drawn beneath the insole on a conventional heel seatA lasting machine.

The outsole. 25; with its cover section 2T and platform 20 are nailed or cemented together as at: 26, amhe'el lift 28 and heel 2S are nailed to the overlying parts as at 30'.

In making my shoe, I prefer to proceed as follows:

The upper of the shoe is put together in the conventional manner, either lined or unlined, and either with or without a counter pocket and counter.

The insole I5, constructed with lip I'l sewed or channeled as closely as possible to its edge without having the stitches pull through, and provided either with or without Gem duck, is next tacked in position on the bottom of the last, after which the upper is pulled over and side-lasted, and the toe and heel seat then wiped in the conventional manner, in case a wedge is used, the shank is lasted fiat as far as necessary.

Next the forepart section 2I of the platform cover is sewed at its upper edge to the upper and to the lip I'I of the insole in a conventional welt sewing machine, or by means of machines especially adapted for this type of work, such as the Puritan or Union lock-stitch sewing machine. This leaves the free part of cover section 2| projecting beyond the inseam.

The surplus material may now be trimmed from below the seam as close as is safe, and the filler, which may be solid, thermoplastic, spongerubber, or so-called cold ller, is then applied in a thickness equal to the height of the inseam.

The platform, attached to the wedge if a wedge is used and which has previously been rounded to the proper size to give the desired extension, is now covered at the heel part by cover section 21 in such a way as to be slightly lapped in the region of the points marked 22 when the platform is laid properly on the bottom of the shoe.

Cement is now applied to the inner surface of cover section 2l and if desired the margin of the platform section 2|, and the free portion of the cover section is then pulled tightly down over the edge of the platform and firmly pressed against the under face of the platform. In the heel region of the shoe, the free edges of cover section 21 lie against the adjacent surfaces of the upper structure and platform sole, respectively, and are fastened by the lines of nails 26 and 3U, as well as by cementing if desired.

The outsole may be attached either by the cement process or may be sewed through the insole either Littleway or McKay stitched, and either aloft or in a channel.

If the shoe has a Wedge heel, the outsole lies perfectly fiat across the bottom of the shoe.

If the heel is of the conventional type, or spring heel, or square-breasted heel, then it is applied afterwards in the ordinary way.

My method may be applied to wedge type shoes, with at outsoles, by simply covering the rear section of the wedge with a, separate cover piece so that I get a slight lap at the joint 22 with the forepart cover section 2|.

1f desired, I may first adhere the platform and ller to each other and then assemble them in the shoe, or I may construct these parts in one piece and provide them with an offset edge.

While I have described and illustrated a preferred embodiment of my invention and a preferred method of making the same, I realize that the construction and procedure described may be changedsomewhat as requirements may demand. All such Changes are to be regarded as within the purview of my invention if within the spirit and scope of the appended claims.

I claim:

1. A platform shoe comprising an upper structure, an insole having a marginal stitch-receiving lip, a platform sole, an outsole, a heel lift, a heel, and a, sectional platform cover comprising overlapping forepart and heel sections, a line of stitching passing through the upper edge of the forepart section of said platform cover, the lower edge of the upper structure, and said stitchreceiving lip of the insole for fastening said parts together, the portion of the platform cover which is not stitched to said lip and upper structure extending around the edge of the platform sole and being inturned to lie between the platform sole and the outsole, a line of nails in the heel area of the shoe passing through said heel, heel lift, outsole, platform sole and the heel section of said platform cover for fastening said parts to the upper structure, and a separate line of nails in the heel area of the shoe passing through the outsole, the platform sole, and the heel section of said platform cover for fastening said parts to the insole.

2. The steps in the method of making a platform shoe, which comprise assembling together an upper structure, an insole having a marginal stitch-receiving lip, a platform sole, an outsole, a heel lift, and a heel, applying a sectional platform cover comprising overlapping forepart and heel sections to the platform sole, stitching the upper edge of the forepart section of said cover to the insole lip and to the adjacent lower portion of the upper structure, drawing the un- Stitched portion of said forepart section around the edge of the platform sole and fastening it against the bottom of the platform sole, nailing the heel, the heel lift, the outsole, the platform sole and the heel section of the platform cover to the upper structure, and separately nailing the outsole, the platform sole and the heel section of the platform cover to the insole.
