My` present invention relates to boots and shoes, and more particularly to boots `or shoes wherein is incorporated a metallic arch stiffener or supporter, and the instant invention includes se as an article of manufacture. 1

An important object of the present invention is the provision of a boot or shoe whichwill' have incorporated therein an efficient longitudinal arch supporter.

A further feature of my invention resides in so constructing and assembling my `novel shoe and arch supporter that said shoe will have a self-locking arch therein, this valuable feature being created` enirely by the novel details of construction of my novel arch supporter or shank stirfener.

An important result of this self-locking, arch is the fact that the stiffener, when. theweight of the wearer is placed thereon, will be ,forced or pressed toward the longitudinal arch of vthe foot, instead of bending or flexing away there-u from, and thus the wearerrof shoes in which my novel arch supporter is incorporated is Vassured of a constant and entirely automatici arch sup'- port.

, Another object of the invention resides inthe particular construction of arch supporter utilized. The body of` this arch supporter maybe of any `desired size, shape, design or style. That herein illustrated is ofthe well-known cottage shank type, with the important exception of the* forward end thereof which is under the' ball of the foot. This forward end` of thesupporter is curved or spooned, longitudinally but not laterally, theV extreme forward end of said-,spoonror tongue being preferably beveled on its under surface in such manner' as to leave a sharp, .biting upper edge.

Because of the curve of therto'ngue, andthe inherent resilience of the material of which said supporter is constructed, this sharp edge will` be inV constant engagement with the under surface of the insole. When the weight of the wearer or the pressurev of the foot, is exerted on the shoe,

this sharp edge will bite into the said under` surfaceof the insole, automatically locking the A further andimportant feature of my presentinvention` resides in the provision of .wings,rat each side of the forwardly projecting tongue, and

but slightly spaced therefrom, said wings beingV normally .on a plane slightly above'the normal horizontal plane of the curved portion of said tongue. Another Yimportant characteristic of these wings` is the fact that said wings aord a far greater bearing surface for the forward end of the supporter against the outsole than would be possible if the tonguealone were util-ized With-` out said wings. Furthermorathe construction of the forward end `of-my novel supporter, as will be readily apparent to those skilled in this art, enables the said forward end of this supporter to more readily conform to the shape of the outsole and thus more efciently and satisfactorily carry out its function of supporting the longitudinal arch of the foot when said supporter is automatically locked in position as above briefly -eX- plained. The above mentioned wings extend sufficiently far forward inthe shoe to be located under the ball portion thereof, `at each side of the spooned tongue, and thus my novel supporter presents to the fullest extent, a complete support, not only for the longitudinal arch of the foot, but also for the transverse `or metatarsal arch.

The benefits and advantages of my novel sup porter will be instantly apparent to those skilled in the art, and since I believe that said supporter, as well as the shoe in which same is incorporated, are novel, I have claimed the same in the present application.

All of the above, and other objects and features of the ,present invention, details of construction, and advantages, will be hereinafter more fully pointed out, described and claimed.

Referring now to the drawing, fora particular description of the4 irivention`,-its` construction and assembly, ltd'esignates the' upper' materials of a shoe, assembled on an insole .2y inA the usual' manner. j

Before the ,outsole ,isafxed my novel arch supporter `3; is, applied to the shoe, the rearward edge Iii.

end of this supporter having a pair of apertures 4 therethrough, through which are driven tacks into the insole at the heel portion thereof, this being the only operation necessary to attach this arch supporter to the shoe. This method of attaching the rear portion of my supporter to the shoe is optional, as the method of attaching constitutes no material part of the present invention. The shoe illustrated in the present application is of the wellknown McKay type, and subsequent to the arch supporter attaching operation, the outsole 5 is laid, temporarily secured to the insole, and then permanently, attached thereto by 'through and through stitching, whereupon the heel 6 is attached. The outsole may be temporarily attached atthe forward end before ap,-` plication or incorporation of the arch supporter, if desired. Y

The arch supporter illustrated has a curved body portion constructed similar to the well known cottage shank supporter, but it will be ap- Y preciated and understood that the body portion of my novel supporter maybe of any conventional design, shape, style or size, as the invention of the present application is primarily directed to the forward end thereof, which will now be described.

The forward end of the supporter is spooned or curvedin a direction reverse to the curve of the body. .so that the general longitudinal contour of the-central part of said. supporter is that of a reverse curve. The extreme forward end of the tongue 8 is preferably squared, the -under surface of this forward end being ohamf ered or beveled as illustrated at 9, leaving a sharp forward upper Located at eachside of the central tongue 8 is a wing I i, these wings extending forwardly with said tongue for a material portion ofits length, but as will be apparent from an inspection of Figs. 3 and 5, said wings are normally on a plane slightly above the normal horizontal plane of the tongue il` at the lowermost part of its curve. These wings il extend forwardly under the ball of the foot, and constitute ample bearing for the supporter in the shoe, toprevent twisting, turning or other distortion thereof, and Valso constitute an additional support, notonly for the longitudinal arch of the foot by reason of the increased length thus added to the longitudinal arch supporting portion of the device, but also for the transverse or metatarsal arch by reason of their location under the metatarsal arch portion of the foot and the bearing and support thus afforded for said metatarsal arch, as clearly shown in Figs.

l, 5, 6 and 7. Furthermore, thesewings H enable the supporter toY more readily conform itself to the shape of the outsole, particularly when the weight of the wearer is exerted thereon.

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 I intoA Contact with the under surface of the insole 2 at the ball of the foot. Thus when the weight of the wearer is placed in a shoe, this will cause said edge l0 to bite into the under surface of the insole, locking the supporter in position between the attaching means at the rear portion thereof and the point at which the edge l0 of the tongue 8 has bitten into the insole.

t The biting of the edge l@ into the insole 2 will never be sufficient to penetrate through the insole, and thus cannot possibly injure the foot of the wearer. In prior shoes of this type, wherein the forward end of the shank stiffener was loose, and free to slide on action of the foot during walking,

the shank stiffener would be forced or pressed away from the arch of the foot, and thus would not have a constant arch supporting capacity.

In shoes where theforward end of the arch supporter has been fixed in position, the expense of manufacturing Ysuch shoes has been increased because of the additional operation or operations necessary to attach said forward end, and the attaching instrumentalities have frequently penetrated the insole, resulting in injury to the wearer, damage to stockings, and other disadvantages. My present novel self-locking arch supporterobviates and eliminates all of these prior difculties and disadvantages.

By my present invention, eliminating separate attaching elements for the forward end of the arch supporter, I am enabled to more cheaply produce a shoe having a metallic arch supporter incorporated therein, while at thev same time assuring the wearer of an automatically or selflocked arch, and constant arch support, and these advantages will be fully understood and appreciated by those skilled in this art. t

While I have necessarily described my present invention somewhat in detail, it will be appreciatedthat the showing of a McKay shoe is for illustrative purposes only, and that I may vary the size, shape, style, type and design of my novel archV supporter or shank stiifener within reasonably wide limitsV Without departing from `the spirit of the invention, or that this shank ward end thereof, whereby, on pressure of the foot being applied in said shoe, said edge will bite into the under surface of the insole, and automatically lock the supporter in position, and a forwardly projecting wing at each side of said tongue terminating short of the outer end thereof and being parallel therewith.
