UNITED STATES PATENT OFFICE FOOTWEAR` Application January 3,

6 Claims.

My invention relates to improvements in footwear construction and a method of manufacturing the same. It is especially advantageous as applied to low shoes such as slippers.

Broadly speaking, the invention consists in preforming a padded insole unit around and to which the upper is thereafter lasted right side out in sucha manner that stitching may be dispensed with as a means for uniting said parts. The invention lends itself to various types of footwear such as the low heel type, the higher heel type, and the sandal type.

My Objectis to provide a method of construction which will produce economically a shoe possessing long wearing qualities by reason of the fact that a heavier outsole can be successfully employed than has hitherto been possible in slippers of the padded sole variety in which stitching and turning has hitherto been regarded as essential, and which necessarilyv called for a thin light-weight Asole material.

Another object is to construct a slipper that will possess the comfort features of a` padded sole slipper while at the same time possessing the appearance of a more expensive hard soled slipper.

Again, by reason of the fact that the padded insole unit, which in the preferred form includes a sock lining, is permanently built into the slipper, shuiiling and loosening of the sock lining with the attending discomfort associated therewith is avoided.

A further object is to provide, at a minimum of expense, a slipper construction ofthe padded r sole type, which simulates in appearance the more costly type. These and other advantages will be appreciated and understood by the mechaniclskilled in this art from a reading of the following description and an examination of the accompanying drawings in which I have set fortlrmyinvention in certain preferred forms.

In said drawings- Fig. 1 is a perspective view of -a nished slipper or shoe of the higher hard heel type, portions being broken away; Y

Fig. 4 is a cross-section on the line 4 4 of Fig. 2;

Fig. 5 is a perspective view of an assembled padded insole unit for the type of slippershown in Fig. 1;

Fig. 6 is a side elevation of my invention as applied to open or sandal type slipper;

Fig. 7 is a cross-section of, the insole on the line 1-1 of Fig. 6;

Fig. 8 is a side elevation of my invention as applied to the padded soletype of slipper having a soft low heel, a portion being broken away.

I represents the sole portion of the padded insole unit, which portion ismade of any suitable material such as buckram. 2 represents a soft padding of suitable material such as felt, the same being permanently secured upon the portion I. 3 represents a sock lining of appropriate material. In that form of the invention shown in Figs. 1 to 5, the parts I and 3 are stitched together along their edges to securely hold the padding 2 in place therebetween and so as to form a single padded insole unit. The sock lining and padding terminate short of the extreme rear end or heel portion of the sole I when the padded insole unit is for slippers of the Wood heel type. 4 is a metallic shank stiilener usually of steel which constitutes part of the assembled unit when the slipper is to be of the aforesaid type. 5 is a cover for the stil'ener 4, said cover being made of suitable material such as tough sheet iibre. The rear portion of this cover 5 is shaped to the contour of that part of the sole I to the rear of the padding l2 and serves the useful purposes hereinafter described. The shank piece 4 and cover 5 are mechanically secured to each other and to y the soleV I by any suitable means such as clinched staples which may straddle the piece 4 to hold it in place. 2 represents a piece of padding which constitutes the heel pad the same being of the proper thickness and shape to cover the 'exposed portion of the shank cover 5. This piece 2 is suitably secured thereto as by cement and is provided with a sock lining 2" for the heel, which preferably overlaps the sock lining 3 for the shank when the slipper is completed as shown in Fig. l.'

As to the method of construction: Starting with a unit such as shown in Fig. 5, said unit (minus the part 2') is tacked onto the bottom of a last. Cement is applied to the margin of theA unit on the exposed side before or after tacking the same to said last. When the upper has been fitted and is ready, the same is subjected to the lasting operation and the lasting allowance 6-6 l is secured to the insole margin by any suitable means such as cement, staples, or otherwise. In that form of the invention shown in Figs. 1 to 5, it is contemplated that a counter will be used, the

same being indicated` at 1 (Fig. 4). Before the r heel padding 2 is applied, the quarter portion of the upper with the counter assembled therein may be lasted and clinched to the rear portion of the insole in the usual manner, as by clinched tacks or nails 1 1. The parts at this stage are now ready to be prepared for the usual outsole laying operation. When prepared the outsole 8 is applied and securely and permanently attached by any appropriate adhesive process employing preferably a powerful waterproof cement. The last is then removed. 9 is a hard heel, preferably of wood, which is secured in place by any suitable mechanical fasteners such as screws or nails IIl-I Il which may be driven through the rear portion of the piece 5. The pad piece 2 and the lining 2 are then securely cemented-in place.

In Fig. 6 I have shown a modification of my invention as embodied in a slipper of the open or sandal type, and in which it is highly important that the padded insole unit should present a finished appearance at the edges and throughout the area exposed to View through the open sides. In such a type of slipper, instead of uniting the members of the unit around the edges by over- -stitching, such as shown in Fig. 5, I employ any method which provides a smooth exposed edge. Such a padded insole unit is shown in Fig. 7, wherein instead of securing the edges of the sole portion and sock lining by means of overstitching, I provide a stripping II around the edge of said insole, which covers the edge of the padding and is suitably secured to said sole portion and sock lining, thereby furnishing a smooth finished edge for the insole unit. I2 represents stitches which constitute onemeans for securing the stripping II to the sole portion and the sock lining. Inasmuch as the preformed padded insole unit should be tacked to the last before the upper is lasted, and inasmuch as the upper is sometimes temporarily tacked to the insole, it is obvious that the removal of these tacks would leave holes in the sock lining, which, in the case of a high class sandal type slipper or shoe, would be objectionable. I may avoid this during the preliminary operation by using a piece of inexpensive material in place of high-grade sock lining material, and a lining of proper material might be cemented in place as a final operation. In some cases. the preformed padded insole unit might comprise the sole I and a pad 2 permanently secured together as by adhesive or stitches, in which event, if desired, a so'ck lining could later be secured in place.

Fig. 8 represents my preformed padded insole unit as applied to aslipper having a low soft heel, that is, not to be attached by nails or screws. In this case, the shank piece 4 and cover 5 are omitted, and the padding 2 may be of one piece extending from end to end of the insole. As in the previous cases, the upper is lasted right side out on the preformed padded insole unit and the lasting allowance is gripped between the margins of the insole and outsole as previously indicated.

In all of the above forms, the area on the lower side of the insole I within the edges of the lasting allowance may be filled in flush with the surfaces of the latter by a suitable strip of material of the proper thickness and outline so as to give the proper bearing for the outsole, such a filling being indicated at I4.
