To all whom it may concern: I i

Be it known thatT, OsKAu SEMELEDER, medicine doctor, a subject of the Austro- Hungarian Emperor, residing at V. .Franzensgasse 24;, Vienna, in the Empireof Austria-Hungary, have invented'an Improved ,Apparatus for Correcting Foot Crookednesses, of which the following is aspecification.

I have found that the flat-foot arises not only, as it is hitherto suggested, simply by pressing down the foot vault, but also by distortion of the leg relatively to the foot around an axis passing at A (Figure 1) behlnd the heel 3011111. The inner ankle,wh1ch is situated normally at B moves by this distortion in the direction of the arrow 50 into the flat-foot position B and the leg together with the ankle will be distorted inwardly.-

The apparatus embodying the invention consists essentially in means by which,-while avoiding an action upon the knee-joint, a distortion of theankle of theflleg will be effected in such manner that the ankle will be turned into the normal position. Accord ing to the present invention the said effect will be obtained in such way that a leverage produced by the bodyweight of the patient will act upon a" splint, which is to be faste-ned on the leg and iscapable to be rocked at rlght angle to'the direction of golng, in:

such way, that the said splint is allowed to rock in the manner of a togglelever 111 a direction oppositet-o the ankle, i. e. in "the direction indicated by the arrow-y (Fig. 1), Whereas ajrocking in the other dii'ectionwill be prevented. By this means will be efiected that a leverage takes placeonly in'the desired direction, so that the leg (ankle) fixed by belts or sockets or by the shoe or the like to the said splint will be brought into the normal position and held fast in thejsame. The above mentioned effect will be still improved by arranging the splint so, as to be capable of rocking also in the direction of going, whereby the natural turning motion of the foot in the ankle-joint on walking is not prevented. 3

Fig. 1 is a diagrammatic plan view illustrating the operation ofthe improved apparatus. Figs. Zandiw ofthe annexed drawing show an apparatus according toithe present invention in two functional positions. Figs. 4:

and 5 show details. l

1 which' rests only at. oneside and will in,

setting thefoot on ground contacting theq latter at firstxbythe edge 2.

' is a splint Whihisconnected at the lower end tothe foot treadl either rigidly" or by a, joint or the like so as to be capable of' adpisting at different angles. The upper endof the said splint" 3, is connected by a:

joint 4 to anintermediate piece 5. The latter is connected by a hinge 6, which allows theturning of the splint in the direction of i going, to a bar *7 which may be'secured to theleg, by, afrim 8 or a belt or socket or the like either rigidly or movably by a-hinge 9.

By the Weight of the patient the angular lever 1, 3 will be'rocked about the edge Qjand the side bars 3, '7 about the hinge or'jointl in the mannerwof a toggle'joint (Fig. 3).-

The belt or band 10-being applied around the ankle and secured at 11am 12 byzmeans y e The angle position between the bar 3 and the bar 7 may be. altered for example byan adjustable stop. In the example illustrated the said adjustable'stop will be formed by a screw 6. which is passed through the hinge ,bolt The angle positionbetween the said Eparts'3 and? may also be alteredby'bend ing the bar 7 Moreover the angle position between the fo'ot'tread 1 andfbar 3 may be alteredby ajointcapable of being adjust-ed I and looked as by a joint provided with a stop'14 (Fig. 5). The bar 3 may also be .re-

movably mounted on the'foot tread, as, for j instance, by being passed into a suitable socket or recess as shown for example in Fig. 5,:the said parts may be arranged and connected in any other suitable manner.

The tilting edge 2 maybe shifted or adlengthening or shortening the lever justed by arm 1 for example in such manner, that the;

lever arm 1 isprovided with .a sliding part 13 which by moving in one direction or the other eifects the lengthening or-shortening of the said lever arm'(Fig. 4L).

Conveniently the hinge 4 is arranged above the hingeG, increasing thereby the defiection of the rocking toggle joint.-

As, (outer ankle) Fig. 1 is being moved from C to C by the opposite distortion of the shank relatively to the foot (arrow y), the same apparatus with reversed arrangement may be used for correction of the club-foot.

I claim as my inventi0n 1. An orthopedic appliance for correcting foot deformations comprising a base or tread, and a supporting member for the base connected therewith at one side and adapted to be secured to the leg, said member-being capable of bending and folding in a directionaway from the ankle and perpendicular to the direction of walking under the leverage exerted by the weight of the body causing the base to turn about an edge thereofto exert pressure on the ankle at right angles to the direction of walking.

2. An orthopedic appliance for correcting foot deformation comprising a base supported at one side, a memberradapted to be secured to the leg,- and forming with the base a toggle lever folding in a direction away from the ankle and at right angles'to the direction of walking, and means to limit the folding of the toggle lever in the opposite direction said toggle lever being actuated by the weight of the body around one of the edges of the base. h

3. An orthopedic'a'ppliance for correcting footdeformations comprising a base supported at one side, a member adaptedto be secured to the leg,.and forming with the base a toggle lever, folding in a direction away from the ankle and perpendicular to the direction of walking, said toggle lever beingactuated by the weight of the body around one of the edges of-the base and means permitting movement of the member secured to the leg in the walking direction.

4. An orthopedic appliance for correcting foot deformations comprising a base or tread normally contacting with the ground only at its edge adjacent one side of the foot,

in the case of a clulrfoot, the point C a bar or splint adapted to be secured to the leg, and connections between said tread and splint including two pivots extending substantially at right angles to each other, the pivot allowing movement perpendicularly to the walking direction being arranged higher than the pivot allowing movement in the walking direction.

5. An orthopedic appliance for correcting foot deformations of the character referred to, comprising a base or tread normally contacting with the ground only at its edge adjacent one side of the foot, a bar or splint adapted to be secured to the leg, and connec tions between said tread and splint including two pivots extending substantially at right angles to each other, for the purpose describe 6. In an orthopedic appliance for correct ing foot deformations in which the Weight of the body acts by leverage upon the de formity, the combination of a base or support, a bar adapted to be secured to the leg and connected with said foot support b} means I permitting away. from the ankle and perpendicular to the direction of walking. and an adjustable step for limiting movement of the bar in the opposite direction.

7. In an orthopedic appliance for correct Ling foot deformations in which the weight of the body acts by leverage upon the de forinity the combination of a base or support, a bar adapted to be secured to the leg and connected with said foot support by means permitting movement of the bar away from the ankle and perpendicular to the direction of walking and also movement of said bar in the walking direction, and an ad just-able stop for limiting movement of said bar toward the ankle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. i DR. OSKAR SEMELEDER.
