EDGAR M. DENNISTON, F BURLINGTON, IOWA.

ANKLE BRACE.

Application filed January 14, 1925. Serial No. 2,322.

To all whom it may concern:

Be it known that I, EDGAR M. DnNNIsroN, a citizen of the United States, resident of Burlington, in the county of Des Moines and State of Iowa, have made a certain new and useful Invention in Ankle Brace; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon. which form a part of this specification.

Figure 1 is a central longitudinal section of theinvention with parts in dotted lines.

Figure 2 is a detail front view of the body of the brace.

Figure 3 is a detail top plan view of the same.

Figures 4, 5 and 6 are detail perspective views of interchangeable floor strips.

Figure 7 is a detail cross section of another interchangeable floor strip.

Figure 8 is a detail perspective view of the top strip.

Figure 9 is a detail side view of another form of body.

The invention has relation to braces for weak sprained or broken feet or ankles, having for an object to provide an improved device to hold the foot and ankle rigidly against bending. Other objects and advantages will appear hereinafter.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings illustrating the invention, the numeral 1 designates the body of the brace, made of sheet metal, woven wire, or of wood, and having an upright portion 2 and a horizontal portion 3, both having parallel sides 4:, and an open front 5 and a round back in the case of the upright portion and an open top 6 in the case of the horizontal portion, said body being adapted to have either the right or the left foot and ankle placed therein with suitable cloth or gauze wrapping for a close fit that will hold the foot and ankle against being bent.

The floor of the body 1 is formed by interchangeable strips 7 of Wood or the like, which differ information but have eac'h rounded ends, the strip shown in Figure 1. having an inclined top surface which will hold the foot pointed upwardly, and whlch is adapted for reversal as shown in a light line Figure 1, to hold the foot point- The device being adapted for use with either foot and to hold the same in varlous positions therein is of considerable advantage.

Either one, two or all three of the floor strips 7 may be used simultaneously as may be required.

In Figure 7 a cross section of a floor strip 7 is shown, having a laterally inclined top surface, whereby the weight of the foot can be made to rest upon either side of the ankle brace.

In Figure 8 of the drawing a top strip 8 is shown which fits over the top of the foot and extends from the instep to the toes, being intended to prevent upward toe motion and to hold the foot in a more rigid position.

The exterior wrapping or bandaging will of course hold this top strip to the foot and both top strip and foot to the ankle brace.

I claim 1. An ankle brace, including a body composed of an upright open-front portion having a rounded back and parallel sides and a horizontal open-top portion having arallel sides, and a removable floor strip fitting within and extending the full length of said body and having parallel sides and rognded ends and being reversible end for en 2. An ankle brace, including a body composed of an upright open-front portion having a rounded back and parallel sides and a horizontal open-top portion having parallel sides, a removable fioor strip fitting within andjextenain the full length of said body andhaviiig parallel sides, and rounded, ends aiidbeiiigreversihle end for end, and amp strip conforming to the top of the foot and adapted to prevent toe motion and hold the foot more rigidly and fitting Within the sides of said horizontal portion;

3. An ankle brace, including abozly com posed of an upright open-front port-ion having a rounded back and parallel sides and a horizontal open-top portion having parallel sides, and a removable floor strip fitting within and extending the full length of said body and having parallel sides, rounded ends, a horizontal bottom and an inclined top surface, said floor strip being reversible end for end to change the inclination of said top surface.

In testimony whereof I affix my signature.

EDGAR M. DENNISTON.
