ARCH SUPPORT Filed July 26, 1929 Q via Patented Apr. 12 1932 PATENT OFFICE.

ALFRED R. BONFIELD, or BROOKLYN, new Yonx ARCH SUIPPOR'I.

Application fildJ'uly 26,

This invention relates to arch supports for shoes, the object of the invention being to provide a, simple, inexpensive, one-piece, llght-welght, solld and non-resilientcast.

aluminum arch support so constructed as to be permanently incorporated in the shoejbetween the outer and inner soles thereof during the manufacture of the shoe. 7

Arch supports as usually constructed are resilient and consequently shift and frequent lychange their elevations, so that it is necessary to adjust andraise the arch, necessarily.

causing considerable inconvenience to the wearer, which operation also not infrequently results in the breakage or splitting of the metal of which the arch support is formed,

thereby necessitating the purchase of a new pair of arch supports. I

Moreover, arch supports as usually constructed are made up of a plurality of members fastened or riveted together and in use these parts not infrequently become loose and, furthermore, are expensive to manufacture. It is also common practice to provide arch 5 supports adapted to be inserted into the shoe by the wearer, but such forms of arch supports are more or less uncomfortable, fre-' quently shift, are not as "effective as they should be, and cause more or less discomfort to the wearer while requiring frequent renewals. I

Therefore, the object ofthe present improvement is to provide a properly-shaped and constructed aluminum arch support so constructed that it can beincorporated in the shoe, and willnot materially add tothe cost of the shoe.

In the drawings accompanying and forming a part of this specificationee Figure 1 is a longitudinal sectional view 1'?) of a shoe this improved arch support in- 1929. Serial No. 381,131.

corporated therein, this view illustrating a shoe for the left foot; 7

Fig. 2 is a cross-sectional view of a shoe. taken on line 2-2, Fig. 1, illustratingthis improved arch support; I

Fig. 3 is a plan view of the arch support removed from the shoe;

Fig. 4 is a cross-sectional view taken on line H, Fig. 3; and i Fig. 5 is ,a perspective view of this improved'arch support. 1

Similar characters of reference indicate corresponding parts in the several views.

Before explaining in detail thepresent improvement and mode of operation thereof, I desire to have it understood that the invention is not limited tothe details of construction and arrangement of parts which are illustrated in the accompanying drawings, since the invention is capable of other enibodiments, and that the phraseology which I employ is forthe purpose of description and not of limitation.

This improved arch support comprises a solid, one-piece, cast aluminum plate and is, therefore, without any resiliency, andhas substantially theshape shown in Fig. 3, which illustrates an arch for the left foot and consists of a cast aluminum member or plate 2 having a relatively broad forward end 3, a relatively narrow rear or heel end 4, and therebetween a gradually thickened, elevated and convex surface 5 for supporting the arch of thefoot, the under surface of this portion 5 being hollowed out or concaved, as at 6, for the purpose of permitting the proper. shaping of the shoe. "The opposed, edge? of the arch member is slightly curved and this edge, together with the edges of the forward and heel parts 3 and 4,is relatively thin, the under face of the plate conforming to the shape of the outer sole of the shoe and comparatively flat. I

The'narrow heel portion 4.- is connected with the convex portion 5 by a relatively sharp inclined edge 8, while the front portion 3 is connected with such elevated portion 5 by a slightly curved inclined edge 9 having, however, less inclination than the edge 8. The top surfaces adjacent to these edges 8 and 9, as at 10 and 11, are slightly curved, or hollowed out or concaved, thereby forming an easy rise to the convex portion 5; While the surface between the edge 7 and elevated portion 5, as at 12, has a very gradual upward convex formation, thus providing a comfortable archefiective to properlysupport. the main archiof the foot.

This improved arch support is thus made solid in one piece Without any connected, members or rivets for incorporation 1n a shoe during the manufacture thereof between the outer and the inner soles for the purpose of supporting the main arch of the afoot, and

when so incorporated it is permanently locatedi'againstshifting and by reason of its non-resilient construction no re-adj ustment, duezto ;wear or use, is required.

Thus it'will'be' observed that this improved arch support, formed of cast alu1ninum, .is-

or arrangement, itis not intended to limit the invention: beyond the terms of the several olaim'sor: the requirements of the prior art;
