INSTEP-ARCH SUPPORT.

Specification of Letters Yatent.

Eat-.sented inne i5, i915,

Application filed January 29, 191:2. Serial No. 674,058.

arch support in which the supporting sur-y face is given forni by the Yjoint effect of two plates, relatively large extent, and the other an auxiliary plate of relatively lesser extent, partly overlying the main plate and entending laterally beyond the inain plate to constitute a wing extension upwardly curved to conform. to the inner plantar surface of the foot arch.

Another object of my invention lis to soy construct the parts of the device that an adjustincnt thereof can be 'readily effected; the two plates, to this end, being made readily separable or detachable so that each plate may be treated separately, at the time the arch is fitted to the purchaser`s foot, to give each plate the most appropriate shape to fit the foot of the individual user".

Other objects of my invention-will become apparent to those sliilled in the art from thefollowing description taken in eonjunction with the drawings, in which- Figure l is a plan view of the inain and auxiliaryplates, with the cover piece shown in dotted lines:l Fig. 2 is a transverse section on line Z--Q of Fig. l, with cover piece in place; Fig. 3 is a longitudinal section on line 3 3 of Fig. l; and Figi is a perspective view of the two plates separated.

ln the drawings 5 indicates the inain plate, preferably shaped in plan to lie longitudithe human foot from a point under the heel thereof to a point under the ball of the foot, and toprovide on its under side bearing areas at both ends. The outer edge of the plate is preferably curved to lie substantially parallel with the outer side of the foot, and its inner edge is preferably shaped approximately to follow the line o f the second inetatarsal and the second cunein forin bones, so that the plate is preferably narrowed in plan at its waistwhere it underliesportions ofthe scaphoid and cuneiform bones.

the one a base plate of appropriate Overlying the base plate 5, l pro vide an auxiliary plate G shorter than the base plate and of such width as to have its outer edge lie within the outer edge of the main plate,

and at its inner edge to extendY up along the 3;

high inside arch of the instep in the forni of a wing extension 7. The edge of the wing 7, overhanging the inner edge of the main or base plate, is preferably slit laterally for flexibility. The two plates are made jointly e5 to provide an arch structure substantially conforming to the instep arch, and each providing a portion of the foot bearing surface.

4Thus the-portions of the inain plate lying beyond the auxiliary plat-e at the ends and the outer side of the latter, are arched to conform to the corresponding portions of the foot and the auxiliary plate is arched longitudinally and curved transversely for substantial conformity witlrthe higher portion A7,5

of the instep arch defined by the under and` inner surfaces of the'ast-ragalus and scaphoid bones. p

The inner edge of the main plate portion at the narrowed waist thereof is preferably curved upward at 9, in conformity with the curvature of the auxiliary plate, and for strengthening purposes the main plate may be advantageously provided witli a depressed bead extending along its higher arched por g5 tion. For use the plates are suitably secured together and their receiving sui-races are overlain by a cover piece il, of appropiiate shape to lit the' shoe, such cover being preferably of leather with the usual sliived 9e edges.

The structure thus far described provides an advantageous arrangement whereby the 4longitudinal central portion of the arch,

higher part of the inwhich underlies the step, is advantageouslystrengthened, and the receiving surface formed jointly by the two plates lends itself readily, in manufacture, to formation in the proper config uration'to support the arch of the foot,'100

thereby to make a very eiiicient and cornfortable support. i I

For effecting most advantageous coperation between the inain and auxiliary plates so that the auxiliary plate may be adequately secured 'to the main plate when in use and yet be readily detachable therefrom, and 'so that the auxiliary plate may eiiqectively merge into the inain'plate in a practically liush Ijoint, l preferably construct iie which the endsl and the outer edge. of the auxiliary plate bear is depressed to a depth of substantially the thickness of the auxiliary/plate so forming a recess in which the .said edgesof the auxiliary plate `may neatlyI lit, leaving the foot receiving surfaces of said plates 5 and 6 flush at their joints. The .n

end Walls of the recess 12 thusl provided U n preferably converge somewhat andmerge 1n appropriate curves into the side. Wall 13, which forms a shoulder or abutment against which 4the outer edge of the auxiliary plate may bear. rlhe leather cover piece is preferably secured to the main plate only, so as to form with said Ina-in plate a pocket into which the auxiliary plate may be readily inserted and from which it is detachable. Preferably 'two rivets lli located near the inner edge of the main plate'and close to the end Wallof the recess 12, to secure the cover piece to the main plate. In such position the rivets 14 act as a guiding means to direct y.the insertion of the auxiliary plate into sition of use, from the inner side of the evice.- To obviate all possibility-of the outer edge of the auxiliary plate 'riding over the shoulder' 13 and taking an improper position with respect to thevmain plate-5, I provide Within the confines of the recess 12, near the Wall 13, aflat headed rivet I5 and provide in the auxiliary plate 6.a corresponding notch i6, with its edges beveled as at 17, so that,

- as shown inFig. 2, the head of the rivet 15 lying substantially flush with the top of the auxiliary plate 6, may act as an effective retainer for said auxiliary plate.

lt is obviously advantageous that an in! step arch support be readily adjustable to the .foot of the individual user and this de- .sid `nncribed.v AManifestly the auxiliarypla'te b may be readily detached from its position in use; may be easily formed tothe desirable curvature to fit the highest part of the instep' arch; and further,l for elevation or depression of the higher side of .the arch' the inner edge 9 of the main plate, may be raised or lowered thereby to change the effective bearing point of the auxiliary plate` and fixing to a certainextent' the desiredA adjustment ofthe auxiliary member. When proper adjustment is made the auxiliary ,plate may be readily slipped back into its pocket, and detained against accidental displacement. by the positioning means described. If desired the main plate may be sold in conjunction with aplurality of 'differently arched auxiliary plates, so that the user may select the auxiliary yplate of conformation best suited to his feet.

While I have herein described'an embodiment of my invention it will be apparent to those skilled in the art that Amanges may be eratum is subserved by the constructionr made in the details thereof Without depar-i.
