w. E. coPlTHoRN ARCH SUPPORT June 7, 1938.

Filed oct. 22, 195e Patented June 7, 1938 UNITED STATES PATENT OFFICE y p Anon SUPPORT Walter E. Copithorn, Natick, Mass. Application october 22, 1936, serial No. 107,031 v 8 Claims.

This invention relates to an arch support to fit within a shoe and which is adjustable.

A person often requires a change in his arch support to raise or lower its height, and inasmuch as the ordinary arch support is non-adjustable a new one must be bought before the old one is worn out, thereby causing extraexpense and inconvenience. One object Vof my invention is to provide an arch support which is readily adjustable to any height desired by merely replacing one member. Another object is to provide such a simple arch support that its adjustment can be changed' by an unskilled person in a few minutes, and which change requires the use of only a single, inexpensive part.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts such as is disclosed by the drawing and specication. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to said disclosure; but am entitled to all such changes therefrom as lfall within the scope of my claims.

In the drawing:

Figure 1 is a plan view of my arch support, the dot and dash lines indicating the outline, of a shoe.

Figure 2 is a sectional view of my arch support.

Figure 3 is a sectional view taken on the line 3 3 of Figure 2.

Figure 4 is a view, showing various parts used in my arch support.

As illustrated my arch support has a top covering Ill usually made of leather and sometimes called a sock lining, and next to it is a padding member II, consisting of a perforated piece of rubber, for protection and to provide a cushioning effect. Then cornes a heavy piece of leather I2 or other suitable material which serves as an anchor `to which other parts are secured. A curved arch plate I4, preferably made of spring s; metal, has holes lB through which rivets I5 pass that are fastened to. said anchor piece I2. A small piece of metal I'l of angular shape is adjacent to and preferably slightly spaced from said arch plate I4 andA has a hole i9 therein through which a rivet i3 passes that is fastened to said anchor piece l2, and serves as a brace at this point. It also has two bolt holes 2B later referred to. This member Ii permits my arch support to readily flex at the metatarsal joint in the foot.

There is an outside, bottom covering 22, and

slightly in perspective,

curved, arch spring plate 25, which is removable,

thereby making my arch support readily adjustable by merely removing said spring plate and.'

substituting another of a different curvature as desired. This plate is held in position at the forepart of the foot by small bolts 26 which extend through the anchor piece I2, the heads of said bolts preferably being countersunk therein, through the angular piece I1, the bottom covering 22 and holes 2l in said spring plate 25. Screw threaded nuts 28 screw on said bolts 26 and hold said spring plate 25 in place. f The rear end of saidspring plate 25 is unattached and has a curved portion 29 bearing against said bottom covering 22 which is free to move longitudinally as the person using it walks. My arch support is merely inserted in a shoe 30 and need not be attached thereto. When the height or adjustment is desired to be changed the arch supportis removed from the shoe, the said nuts 28 are taken on, said spring plate 25 removed and another substituted in its place. While one bolt 26 would be sufcient to hold said spring plate 25 the use of two said bolts 26 prevents any lateral movement of it, and is, therefore, preferable.

-What I claim is:

1. An arch support comprising a top covering, a padding member, an anchor piece, an arch plate fastened to said anchor piece, a separate member adjacent said arch plate and fastened to said anchor piece, a bottom covering, stitches holding said top and bottom covering together with said padding member, anchor piece, arch plate and separate member between them, an arch spring member outside of said bottom covering, and a` plurality of bolts and removable nuts to hold said arch spring member to said anchor piece, said bolts extending from said anchor piece through said separate member, bottom covering and arch spring member.

anchor piece, a separate member adjacent said arch plate and fastened to said anchor piece,

and an arch spring member outside of said bottom covering, and means to hold said arch spring member extending from said anchor piece through said separate member to said arch spring member.

4. An arch support comprising a main supporting member embodying an arch plate, a separate member fastened to and Within said main supporting member, adjacent to and forward of said arch plate, an arch spring member outside of said main supporting member, and means to hold said arch spring member extending from said main supporting member through said separate member to said arch spring member. Y

5. An arch support comprising an outside covering, an anchor piece, an arch plate fastened to Said anchor piece, said anchor piece and arch plate being vintermediate said covering, and an arch spring member outside of said covering, and means fastened to said anchor piece at one end and to said arch spring member at the other to hold said arch spring member, said means embodying removable means whereby said arch spring member may be removed and replaced.

6. An arch support comprising a top covering, anchor means, an arch plate fastened at both ends to said anchor means, a bottom covering,

means to hold said top and bottom coverings, anchor means and arch plate as a unit with said anchor means and arch plate intermediate said coverings, an arch spring member outside of said bottom covering, and removable means to hold one end of said arch spring member to said anchor piece, the other end being free.

'7. An arch support comprising an anchor piece, an arch plate fastened to said anchor piece, an arch spring member, a pin member extending from said anchor piece at a point beyond the end portion of said arch plate to one. end of said arch spring member, and separate removable means to hold said pin member to said arch spring member.

8. An arch support comprising a padding member, an anchor piece, an arch plate fastened at both ends to said anchor piece, a separate member forward of and adjacent said arch plate and fastened to said anchor piece., means to hold said padding member, anchor piece, arch plate and separate member together, an arch spring member extending outside of said aforementioned members, and a plurality of pin members to hold said arch spring member extending from said anchor piece through said separate member and the forward end portion of said arch spring member.
