Specification of Letters Patent. Patented Feb, 22, 1921,

"Application led May 11i,` 1920. Serial No. 381,456.

To all whom z'' may concern:

Be it known that I, VVILLTAM N. BARRETT, a citizen of the United States, residing at Meadville, in the county of Crawford and State of Pennsylvania, have vinvented new and useful Improvements in Arch-Supporters, of which the following is a specification.

This arch support is soformed of a plurality of strips that kthe arch can readily conform to the foot, in other words, while there is an ample supporting force there is a degree of iiexibility which allows the support to conform to the shape of the foot. 'l he device readily lends itself also to forming a transverse arch where this is desired.v

I he invention is illustrated in the accompanying drawings as follows Figure l. shows a plan view of the arch, a part being broken away to better show construction.

Fig. 2 shows a section on. the line 2--2 in rig. 1.

Fig. 3 a section on the line 33 in Fig. 1.

rIhe arch is formed with a covering ma.- terial formed in two layers l and 2,' these layers being ordinarily formed of leather andunited by a suitable cement. Resilient strips 3 are provided preferably inthe form of a wire scroll, thus giving a plurality of longitudinal strips and a plurality of transverse strips connecting the longitudinaly strips. 'Ihe strips are embedded in the leather as the two layers are forced together as they are united by the cement. Preferably the strips are of a cross section having equal dimensions, such as round wire, so that suilicient support is afforded by reason of the thickness of the wire leaving the greater portion of the surfaces of the leather exposed to each other so that they may .be readily united by cement. By using such wire a greater number of strips are used and a more yielding structure is formed so that it will more readily conform to the foot. rl`he longitudinal arch is formed at 4the Vlongitudinal strips or portions of the wire maintaining this arch and a transverse arch is formed at 5, the transverse portions of Within the limits to which these arches are subjected this shape. Not `only the longitudinal arch may be readily formed but also a transverse arch, thus permitting the support to be readily fitted to a foot.

What I claim as new is l. An arch supporter comprising a plurality of longitudinally disposed strips of equal cross dimensions; and a covering'having two layers one on each side of the strips, the strips being embedded in the covering, the layers being cemented'together between thev strips. v

2. An arch supporter formed of a scroll of wire, the longitudinal parts of the scroll being arched to form the support.

An arch supporter formed of a scroll of wire, the longitudinal parts of the scrollv being arched to form the support, one series of the transverse strips formed by the scroll being arched to forni a transverse arch.

4. An arch supporter formed of strips of vwire extending longitudinally of the support, one of the wires being bent at one end forming a transverse extension onthe longitudinal strip.-

5. An arch supporter formedof strips of wire extending longitudinally -of the support, a pluralityv of said wires being bent at one end forming transverse extensions on the longitudinal strips.

6. An arch supporter formed of strips of wire extending longitudinally of the support, one of the wires being bentA at one end forming av transverse extension on the longitudinal strip, said strips having equal cross dimensions; and a 'covering for saidv strips comprising two layers in which the strips are embedded, the intervening portions of the layers being secured together by cement.

In testimony whereof I have hereunto set m hand. f f
