V Another object of the invention resides in the provision of an automatically locked arch,

ture of the arch supporter or shank stiffener utilized in said shoe.

An important result of this locked arch is that the supporter, when the weight of the wearer is placed thereon, will be brought toward the foot, instead of bending back or away from the foot thus assuring a constant arch supporting function. This feature is extremely important, as when the supporter v is allowed to yield or bend back, it does not permit or provide full. arch supporting ca-' pacity.

utilized. The body of this arch supporter is of the well known cottage shank type, with the important exception of the forward end .30 thereof which is under the ball of the foot.

This forward end of the supporter is spooned,

longitudinally but not laterally, the extreme forward end of said spoon beingbeveled on its under surface, in such manner as to leave shape of the ball end 0 the supporter, this sharp edge will be in constant engagement with the under surface of the insole.

which same is incorporated, are'novel, I have claimed the same in the present. application. The above and other objects of the invention details of construction, and'advantages, will be hereinafter more fully pointed out,

described and claimed.- V

Referring to the drawings, illustrating a preferred embodiment of the invention,

Fig. 1 is a side elevation of a'ladys pump, partially in section, with my novel archv supporter in position;

, Fig. 2 is a vertical sectionalelevation on the Fig. 3 is .a fragmentarylongitudinal sectional View, on an enlarged scale, illustrating theforward end of the shank stiffener, and its position in the shoe relative to the insole Fig. tisfa top pla'nview of the archsupporter; and' if i Fig. 5 is a side elevation of said archsupporter.

Referringnow to the drawingsfora particular description of the finve'ntion, its con struction'and assembly, 1 designa testhe upper materials of a 'shoe, assembled "on an in illustratedin the pres'entapplication is of the well-known'McKay type, and subsequent to the ,arch supporter attaching operation,

the outsole 5 is laid, temporarily secured to r the insole, and: then" permanently atta'ched thereto by through and'throu'gh stitching, whereupon the heel 6 is attached: The out sole may be temporarily attached at the forward end before installation or incorporation of the arch supporter, if desired;

- The shank stiffener illustrated hasa curved body portion! constructedsimilar to the well known cottage shank supporter, the forward end 8 of this supporter being spooned or P curvedinia direction reverse to the curve of thebodyfljso that the general longitudinal contour of the supporter is that of a reverse curve. The extreme forward end of the supporter is squared, the under surface of this forward end being chamfered or beveled as illustratedat 9, leaving a sharp forward upper edge 10. When positioned in the shoe, between the insole 2 and outsole 5, as clearly illustrated in Fig. 3, the spoon end 8 brings the sharp edge 10 into contact with the under.

surface of the insole 2 at the ball ofthe foot. y

Thus when the weightof the wearer is placed in a shoe, this will cause said edge -10 to bite into the under surface of the insole, locking the supporter in position between the prongs 4 and the point at which the edge 10 of the supporter has bitten into the insole.'

The bi' ing' of the edge 10 intothe insole 2 will never be suflicientto penetrate through the insole, and thus cannot possibly injure the foot of the wearer. In prior shoes of this type, wherein the forward end offthe shankstiffener was loose, and free to slide on action of the foot during walking, the shank stiffener would bend back away from J the arch of the foot, and would thus not have a. constant arch supporting capacity. In shoes where the forward end of the arch supporter has been fixed in position, the expense ofinanufacturing such shoes has been increased due to the additional operation or I operations necessary to attach said forward end, and the attaching instrumentalities have frequently pene'trated the insole, resulting in injury to the wearer, damage to stockings, and

- other disadvantages.

By my present invention, eliminating separate attaching elements forthe forward end of the arch supporter I am enabled to more cheaply produce a shoe having a metallic arch supporter incorporated therein, while at the same time assuring the wearer of an automatically or selflocked arch, and constant arch support.

"1e I have. necessarily described my present invention somewhat in detail, it will beappreciated that the showing of; a McKay shoe is for illustrative purposes only, and that I may vary the size, shape, style, type and arrangement of parts within reasonably wide limits witho'ut departingfrom the spirit of.

the invention. 4 n

My nvention is further described and defined in the form of claimsas follows:

In a boot of shoe, an insole, an outso'le,
