Specification of Letters Patent. Y Patented Aug. 9, 1921 plantation sied July 12, 1919, serial No. 310,457. Renewed November 27,*1920.k serial No. 426,849.
Be it known that I, JOHN F.
f of New York, in the county of New York `and State of New York, have invented cer# tain new and useful Improvements in Arch- Supports;` and I do hereby declare the fol` lowing to be a full, clear, and exact descrip'- tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to shoes and more particularly to abrace for preserving the arch of the foot, the object ofthe invention being to provide an improved, simple and efficient brace adapted to be permanently secured in the shank of the` shoe between the 'inner and outer-"soles, such brace being so* constructed as to permlt the natural elastic movement of the foot at all timesand under all conditions and yet maintain the arch of the foot in proper osition. v
In the drawings, igure 1 is a longitudinal sectional view of the lower lportion of la shoe showing my improved karch support. Fig. 2 is a top plan view. Fig. 3 an endview.
Referri 0 to the drawings, A indicates the inner solel:
My improved brace is formed from a single piece of resilient material, preferably metal, appropriately` arched and includes a' body portion l, heel portion 2 and toe portion 8, each of which latter portions is bifurcated to provide for more certain elastlcity of the brace without lessening .themaximum supporting strength ofthe body portion. The
complementary resilient supporting members 5, 6, which are produced by centrallyslitting the heel portiony 2, arev similarl in shape and each is transverselyrcorrugated,
as at 7 and provided with an aperture 8 through which a nail may be passed to permanently secure'the brace to the shoe. rIhe part 9 forming one of the two resilient supporting members of the forward or toe portion 3 of the brace, and produced .by the divergent slit of this portion, lies in a plane approximately parallel to theflongitudinal center line vof the support as a whole, while the part 10 forming the other of the -resilient supporting members ofthe forward or toe portion is in a'planetangent to the i ylongitudinal center line of thesupport," and KOLKEBE OK,
the Outer sole, and() the heel inf plan view the center lineofthe member .c The brace as a whole is arched to 4the' normal contour of the human foot, the body portion being concaved so as c to form a cradle-like rsupport. for the foot, and byV reason of the bifurcated end portions a ren silient supportA is produced, the corrugated ends of the members 9and 10'` taking just rsuflicient hold `upon theinner and lOuter Y soles. of the shoe to prevent undue slipping ,of the members and allowing a play between thebrace .and the shoe to afford theV necessaryresillency to compensate for` relative movements between the foot and shoe. The
brace constructed as described is without 1 angularity in any part. y
The manner of fabrication of a kshoe with my improved arch brace as an'integral part j thereof will be manifest lto those skilled in the art of manufacturing boots and shoes. I claim as my invention: 1 f
instep brace formedfrom a single piece of so 1. As an article of manufacture, an arch 'and` material arched to conform Vto the human I foot andvhaving its ends-slitted longitudinally tol form resilient supporting members,
the extremities of said members being trans versey corrugated.
hoe including an arch and instep braceformed from a single pieceof material and `having a body, forward and; rear portions, the upper face of the body portion bel ing concaved, and having its side edges in thesame horizontal plane, the forward` portion having two members spaced apart, one of said members extending straightforward Afrom the body portion and the other, of
greater length, extending f1 forward and curved outward, andthe rearportion being centrally slitted to form two members ofv corresponding formation, said forward', rear loo and bodykportions being arched to conform to the human foot and without angularity in i i the connections betweenV the several parts.
