ARCH SUPPORTER.

Application filed June 15,

To all whom tm/ay concern.'

Be it known that I, JACOB TIsoHMANN, a citizen of the Republic of Argentina, residing at Minneapolis, in the county of Henne ein and State of Minnesota, have .invented certain new and useful Improvements in Arch Supporters; and I do hereby declare the following to be a full, clear, and exact description 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 a foot-arch supporter.

In present constructions, the springs or movable parts wear away or form cavities in the sole of the shoe in which theyare disposed and aside from thus unduly injuring the shoe, the supporting. function becomes negligible as the springs may move to a greater extent than originally intended and will thus lack the support afforded by the sole initially. It is the primary aim or the present invention to provide a novel, improved and simple construction which will overcome the disadvantages enumerated.

Another object is to provide a construction having means to mount the archsupporting parts which is incapable of rela tive movement with respect to the sole of the shoe so as to prevent wear thereof and which means itself forms the supportingl means for the parts and is incapable of undue wear through the action thereof.

A third object is to provide a construction having a mounting or base plate to which the arch-supporting spring or springs are connected, and which mounts a stud to limit the depressing movement of the spring or springs.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating one practical embodiment.

In said drawings Figure 1 is a plan view of the attachment;

:Figure 2 is a side elevation of the attachment;

Figure 3 is an inverted plan view thereof;

Figure 4 is a central transverse sectional View on the line 4-4 of Figure 1.

Like reference characters: designate like or similar parts in the different views.

base plate of any suitable shape and size is provided at 10. It is preferably adapted to b e disposed within a Shoe and rests on tl e sole thereof as lusual and to this end to conform at its rear and side edges to the contour of the heel and upper. It is obvious of course that the plate will be made in rights and lefts, the example shown being a right, and in the case of a left the plate being inverted from the position shown. The plate may be made of any suitable material but preferably of metal.

The arch-supporting means for the foot is disposed over and connected to the base plate 10. This support may consist of a plurality of metallic or other supporting leaves 11, preferably arch-shaped to conform to the arch of t-he foot. Said leaves 11 are resilient and adapted to normally assume the position shown in the drawings. Lowermost leaf 11 as at 12 is riveted to the base plate 1() while the luppermost leaf 11 is riveted as at 13 to the lowermost leaf 11. The opposite ends of the leaves 11 are free, one of them resting on the base plate 10 and having the other in Contact with it.

The uppermost leaf 11 may be suitably covered by a blank or sheet of leather or other material as at 14, which is secured in place as by means of the rivets 13 and a rivet at 15 passing through the leather and the uppermost leaf 11.

B-iveted or otherwise secured as at 16 to the plate 10 is a post or stud 17 disposed substantially centrally under the leaves 11 and terminating at a distance below them and adapted to limit the depressing movement of the leaves.

In use, with the plate 10 in engagement with the sole of a shoe. such sole will not at any time be engaged by the leaves 11 and hence they cannot wear the sole away or pro-vide cavities therein. All movement of the leaves 11 occurs on the plate 10 and the extent of their depression is limited by the post or stud at 17. It is obvious that the foot directly engages the leather at 14 as usual.

As merely one practical embodiment has been illustrated and described, it is to be understood that changes in the details may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention An arch supporter including a rigid base plate adapted for disposition within a shoe and to fit the shoe against movement independently thereof, a resilient leaf disposed over said base plate, a fastening securing the leaf to one end of the base plate, the leaf being free at the other end, a leaf of less length than said leaf and disposed thereon, a fastening securing the second leaf to the rst leaf and adjacent the first mentioned fastening, a covering over the second leaf and first leaf secured in place 'by the second mentioned fastening, a fastening securing said cover to the second leaf adjacent its free end, a stud intermediate the base plate and first mentioned leaf and normally out of contact with the latter, said base plate being 15 JACOB TQISCHMANN.
