I g memo imam filed am-14.1w. ser al no. 504,802.

This invention relates to shoes, and par ticularly welt shoes arranged to provide 1ncreased support for the arch of the foot.* y

It is customary to provide an arch-supporting shoe'with an inner sole whlch has an integral lateral extension adapted to fit beneath, and provide increased support, for, the arch of the foot. Such an mtegrallyw formed inner sole, however, is relatively ex pensive as the lateral extension, necessarily, is oi the same material as the inner sole, and the shape of the inner sole and mtegral' extension is or may be suchthat the wastage of cutting the inner soles is increased.

An object of this invention is to provlde an arch supporting shoe having an inner sole and a lateral extension so arranged that, both may he formed from different pieces and grades of leather. I

A. further object is to provlde' a shoe wherein the arch-s porting extension is lasted-in between the upper and inner sole of the shoe and united. to the inner sole by the stitching which unites the upper and "weltto the inner sole.

A further object is generally to improve- .the construction of shoes and methods of making them; '1

Fig. 1 is 'aplan view of a'shoe embodying the invention ,with the upper partially cut away to illustrate the inner sole andlateral arch-supporting extension.

Fig. 2 is a plan view of the 'inner sole of" the shoe with the lateral extension tempo rarily attached thereto.

Fig. 8 is a. plan view'of the bottom face of the inner sole of Fig. 2. g r t Fig. 4 is a section along line of Fig.

process wherein the edges are trimmed ofl below the temporary attaching means for the extension and inner sole.

Fig. .8 is a transverse sectional detail of the shoe with the outer sole stitched to the welt. a

The completed shoe einbodyin this in;- vention has the inner sole and t e lateral extension '11 which is disposed within the" shoe and is adapted to provide increased support for the-arch of the foot. The inner sole' and extension are formed separately and are secured permanently together in the process of manufacture of the shoe. The extension may be of-an suitable or desirable shape and, preferab y,-is formed with the substantiall straight outer edge 12 which-also is skiveci to a thin edge so that it will not distort or bulge-the upper. The

inner sole and extension may be made of. pieces of leather, for

diiferent grades and economy of manufacture.

The inner sole 10 is or may be of more or less usual construction and may have the usual lip-14 on its bottom face, to whichgthe upper and welt is adapted to bestitched, and, in accordance with this invention, the

lateral inner-sole extension 11 is also .at-

tached to said'lip.

In the process of manufacture of the shoe embodyingthe invention the bottom and in ner edge of the inner sole is skived to a thin edge as at a, Figs. 4 and 5, along that ortion adapted to receive the extension, w ereby to provide a smooth and substantially continuous inner face between the inner sole and extension. N J

The extension 11 is adapted to extend along the inner side of the inner sole preferabl from the heel end of the Ii 14 to the bal -portion of the inner sole. gaid extension is first temporarilyvattached to the inner sole by staples 15 which are passed through the edge of the extension and the lip 14 of the inner sole; and the staples may be applied 'in any usual or desirable manner, as by astapling machine. If desired, an adhesive may be used to securev the extension to the inner sole prior to inserting the staples whereby the better to hold the extension in place durin the staling operation. Thestaples, or a hesive. or

th', are adapted but temporarily-to hold the extension in place during the lasting operation and the application of the permanent fastening means and the staples are sub sequently removed as a further step in the process.

g The inner sole and temporarily-attached extension are then tacked on a last 17, Fig. 6, in a more or less usual manner and the upper 18, and welt 19, are secured to the inn er sole and over the extension by a line off below the staples 15 which served temporarily to attach the extension to the inner sole, and the extension is left permanently attached to the inner sole by the line of stitchin 20.

The s 0e may then undergo further manufacturing operations which include stitching the outer sole 22 tomthe welt as indicated in Fig. 8.

As thus formed, the separate inner sole extension is built into the shoe, and the shoe may be manufactured at a substantial reneoaeva duction in cost as compared tothat type of shoe wherein the extension is integral with the inner sole.

1 claim 1. A shoe having an inner sole provided with a lip on its bottom face, an upper, and a separate lateral inner-sole extension applied directly upon said inner sole and the lip thereof, and a line of stitching passed through said upper and extension and lip of said inner sole.-

2. An inner sole for shoes having a. lip on its bottom face and a separate lateral extension applied directly upon said inner sole and the lip thereof and having means attaching it to said lip.

In testimony whereof, l have signed my name to this specification. GEORGE A. HURLEY.
