To all wi'iom it may; concern Be it imown that l, Juices W. Armou SMITH, s cilisen of ihell'niicfl Slates. and a i'esideii oi the city of lvioi'i'isiown, in lhe county of ecu Sluice of New Jersey,

have inveniecl cerisin and useful Inn-H pi'ovemenls in llnsiep-fiuppciis, of which the following is e speciiicuiion.

The invention relates to supporters for the such oi the human instep and its objects ore, among others, to provide snoport of greater elasticity than can he slimmed by consii'uc the slippers; c" olel of S'lfilcient thickness to suppoi-l the 's'eigl'it of the Ween-c1, to provide a comparatively soft and flexible support foi lhe middle and side of the instep and to reduce the cost and increase the sciength and durshiliiy oi the device.

The invention consists in line construction, combination and arrangement of parts hereinafter described and cleimeil and illustrated in the accompanying diswings,

in the said drawings Figure l is on under sicle view of u supporter embodying the im provements. Fig. 2 is a. vertical medial sec tion on the line of l.

The main plate A oi the supporter is arched from end to emi from side to side in the usual n'uinnci' lo sppi'oximcle lhe under side of the arch of the human instep but is somewhat flatter than usual, so as to leave room on the topfor the elastic supportin cushion The inner side of the main plate, instead of exieniling upwardly in the usual manner is cut oil, and terminotes in a short upwsivily turned portion A, which not only assists in holding the cushion but adds strength so the support at this point.

The elastic cushion B is preferably made of sponge rubber or some oliici' highly resilient substance so fez the body portion is concerned. and this hocly pOlllOIl extends over the plate from side to side, tapering from points forward and back of the front cncl rear rivets A? i'espectively lo the opposite edge of the plate. The cushion also tapers iron: the miilclle toward itsedges so as to give a incl downward curve to the upper surface with its apex at the middle. The side portion B exteno s upwal dly at an angle of approximately only-live degrees and has s curved outer edge. This side portion also lspers from the line of junction with the slain cushion b0 the outer edge, and

is pi'eiei'zibly reinforced with canvas or some other relatively still materiel E, extending throughout the cushion. 7

The plate A is provicleci "with a depressed rib C extending longitudinally thereof pal allel Willi its inner edge, and this depressed rih receives a corresponding part of the cushion so as to hold the said cushion against lateral. and longitudinal movement. it also tends to strengthen the plate at the middle. The upturned inner edge A. also tends to hold the cushion in position by pressing against the inner edge of the body portion.

By this construction and arrangement a plate of great strength and durability is pro 'ided foe, and the support given the desired resilience and si liness. so that it will not unduly irritate the foot of the wearer. A side portion is also provided which will yield to a much greater degree than could be ctiained by a metal side portion, and which will adapt itself to the shape of the part of the foot with which it comes in contact end of the some time exert s yielding pres sure tending i0 restore the foot to its normel position.

The support is provided with a suitable flexible nonunetellic covering D, and the rivets A pass through ils coveiglhe cushion near its exircuiities and the platev and secure all of ihese parts together.

ill specific feature of the invention is the shape of the cushion and its position relative to the plate. It will he observed that the plate extends from the base of the celcsneuzn or os-cslcis lo the anterior part; of the metatsrsus the instep, and that the cushion is located between the calcaneum will the meistarsus thus bridging the arch ofand fills the triangular sgoece occupied by the under surface of lhe tarsus or middle part of the arch composed of the scaphoid, cuboid and cuneiform bones and the anterior portion of the asimgelus. In this manner a yielding cushion is provided for the complex middle portion of the arch which is ordinarily extremely sensitive and painful in cases oi flail-fool: and at the same time means for raising the arch are provided in the metallic plate extending across the arch, which, as will be understood, may be bent 01" Worked to wise or lower the arch as desired. I

What if claim is:-

i. The combination of a. metallic plate adapted to extend from the base of the calcaneum or os-calcis to the anterior part of the meta-tarsus, said plate approximating the Width of the bony structure of the instep 5 arch, and a cushion of non-metallic resilient 10 the plate, said plate being provided with a depression near its middle and with a turned up inner edge, said cushion having a portion located in said depression and having a portion of its under surface in contact with the 1 turned upiinner edge of the plate.

2. In a-device of the character described the combination of a metal plate and a piece of elastic, non-metallic substance superimposed on the said plate and covering its me- 20 dial portion, the said plate'having a groove extending lmigitudinally thereof and the piece of elastic substance having a portion in combination of a n'ietal plate and a piece of elastic, non-metallic substance superimposed on the said plate and covering its medial portion, the said plate having a groove extending longitudinally thereof and the piece of elastic substance having a portion in said groove, and the plate also having an upturned edge extending over a portion of the side of said piece of elastic substance.
