ARCH SUIPOBT.

Application filed August 7,1922. Serial No. 58034 3.

To all whom it may concern: I

Be it known that 1, CHARLES L. CnAINn, a citizen of the United States, residing at Meadville, in the county of Crawford and State of Pennsylvania,have invented new and useful Improvements in Arch Supports, of which the following is a specification.

This invention is designed to improve arch supports. Such supports must have sufficient rigidity or supporting quality to carry the arch. At the same time they mus conform to the local variations encountered in arches to distribute the support. In accomplishing this I utilize a series of wire arched members preferably of round, or wire having equal cross dimensions which wires are rigidly connected by welding or otherwise with the end plates, the rigid connection with the end-plates retainingthe wires in their'arched form and in proper relation to each other and forming a means to which the pad covering the arched wires may be permanently secured. It is also desirable to provide such a device with means for supporting the metatarsal depression and to have this support adjustable to fit difi'erent conditions. Other features of the invention will appear from the specification and claim.

The invention is illustrated in the accompanying drawings as follows p Fig. 1 shows a section of the support on the line 11 in Fig. 2.

Fig. 2 a bottom view of the support.

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

Fig. 4 a. side elevation of the filler forming the local metatarsal support. v

Fig. 5 a bottom view of the filler.

1 marks the rear end plate and 2 the front end plate. These are connected by the wires 3, the ends of which are rigidly secured by electric welding, or otherwise to theplates 1 and 2. These wires form the arch a's'clear- 1y shown in Fig. l and are so arranged as to be properly spaced across the support. The wires are preferably of approximately equal cross dimensions ordinarily of round wire so as to readily flex not only in the direction of the arch but slightly sidewise if necessary to conform to the shape of the arch of the foot. On the other hand the rigid connection with the plates assures the holding of the wire so that it directs its supporting force upwardly, in other words, it prevents the Wires turning and thus yielding without giving the proper support.

The pad 4 conforms to the general shape of the arch and is supported to at least one of the plates by rivets 5. It has the usual side support 6. Efforts have heretofore been made to secure such pads by means of cements and otherwise but diiliculty has been encountered as to this by reason of the heat, wear and moisture to which the pad is subjected.

The front plate 2 has a transverseslot 7 into which thetongue 8 of the filler 9 extends. This filler is arranged under the pad 4- and forms a local arch 10 for the metatarsal depression. The filler may be shifted crosswise along the slot 7 so that it may be made to conform to the foot of the wearer. This filler may be made of any desirable material such as rubber or aluminum.

The rear plate 1 is provided with an open ing 11 into which the pad'l is depressed. This forms an oscalsis depression in the pad.

I prefer to provide the pad with openings 12 which being over the open wires 3 and these wires being spaced ordinarily from the bottom of the shoe give ample ventilation to the foot.

.VVhat I claim as new is In an arch support, the combination of end metallic plates; and a series of co11nect ing resilient wires of arched form extending between the plates and rigidly connected thereto.

In testimony whereof I have hereunto set my hand.

' CHARLES L. CRAINE.
