To all whom it may concern:

Be it known that I, WILL N. Sncnnm, a citizen of the United States, residing at Fort Scott, county of Bourbon, and State of Kansas, have invented a certain new and useful Improvement in Arch Supports, of which the following is a full, clear, and ex-' act description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, formingpart of this application, in which- Figure 1 is a' sectional View of a shoe showing my arch support in position therein. 1 Figure 2 is a detail view of my improved arch support secured in position on the outer sole of the shoe. i

modified forms.

' This invention relates to an improvement in arch supports, and is designedpartlcularly as an im rovement u on that type of arch support s own in U. Letters atent No. 1,391,584, granted to me September 20, 1921.

The objects of this present-invention are to simplify the construction of arch supports, cheapen the cost of manufacture, and to provide same with means whereby 1t becomes attached to and forms a part of the finished shoe.

In my present invention, as 1n the patent referred to, the main shank portion f the arch support while possessing flexibility to a certain extent is practically rigid, while the forward hinged portion forms an extension of the main shank portion and is likewise practically rigid when'supportlng a superposed load, but whlch forward extension is capable of being flexed or bent downwardly by the peculiar construct on of the hin e. This hinge is practically 1n the form 0 an elbow or rule joint, whereby the hinged parts are capable of relative movement only in one direction, movement 1n the opposite direction being arrested when the parts of the hinge co-act 1n such manner as to provide abutting shoulders which lend stamped from sheet metal forward in:

rigidity to the structure and enable the hinge to support a superpomd load.

In the drawings, 1 indicates the heel portion of a shoe upper,;2' the insole, 3 the outer sole and 4 the heel riser.

5 indicates a metal plate, preferably, r and formed slightly concave on its upper surface, said plate having perforations in its rear end whereby it may be nailed in position to the heel seat by means of nails or brads 6.

7 indicates a rivet which secures the forward end of this'main shank portion 5 to the outer sole at a point preferably slightly in advance ofthe heel.

8 indicates the forward extension of the I shank which is secured to the outer sole by means of a rivet '9 near the ball of. the foot. This shank extensionis provided with rearwardly extending tongues 10 which are staggered with relation to each other, and are preferably flared as shown in Figure 1.1. Wit no weight on the arch the arts are unstressed or in normal position. 1811 the wearer is standing and the arch is weighted between the arrowsjc and d, the points of reaction being at arrows a and b, the arch sections are under compression between the

anchorage points

7 and 9, and the outer sole under tension between these points. The

I end of the main shank portion 5 is meived between the tongues 10 and abuts against the wall formed by the junction. of said tongues and the body por+- tion of the forward extension 8. When the shank portions 5 and 8 are secured in position to the outer sole, and the parts are in the position shown in Figure 1, it is possible, on account of the flaring position of the tongues, to bend the heel portion of the outer sole downwardly in the zone of the point indicated b arrow e, and, as represented bythe dot an dash lines in Figure 1, the flaring lower tongue. permitting this slight downward movement of said heel portion. However, when the heel of the shoe is lifted,- as in walking, as indicated by dotted lines in Fi re 1, the u per ton as 10 contact with t e upper surace of t e free forward edge of the main shank portion 5, at which time the forward edge of said main shank portion engages in the socket formed by the tongues, thereby placing the arch sections in compression-between .their anchoring points 7 and 9 (the outer sole being under tension between these points at this time) thus providing a practically rigid arch structure in which the forward extension 8 constitutes a practicallyrigid extension of the main shank portion 5; but the entire shoe is, of course,.

. portions, as indicated by the dot and dash lines in Figure 1. imposed upon the shank'portions 5 and 8, say at or near the hinge joint (between arrows and d) the anchorage of the shank portions places under tension between the points of anchorage and the shank portions and 8 under compression between said anchorage points.

Hence, substantial rigidity is obtained between the anchorage points. Furthermore,

by nailing or anchoring the rear end ofthe main shank to the heel seat, a firm or rigid support for the arch is provided substantially throughout the length of the shank of the shoe when weight in proper relation is imposed thereon. From the above, it will be observed that the sole of the shoe is flexible at and in front of arrow (1, i. e., can be bent both upwardly and downwardly, as permitted by the up-' per; but that the shank of the shoe can only be flexed at one point, in the zone of the arrow e, and in one direction only, (upwardly) at this point, the shank being rigid to suport a superposed load tending to flex it ownwardly, or in the opposite direction.

By coverm the metal arch support wit the insole, sai insole serves to hold the parts to the shoe and, to eac other, and there is a smooth surface for the wearers foot.

In Figures 3'and L I have shown a modi;

fied form of'hinge in which the main shank portion 5 is formed with a hinge eye 5 substantially at its central point, the metal be, ing cutaway oneach side of this hin e eye. The-shank extension ,8 is formed wit eyes 8 and a tongue 10, the latter resting upon the upper surface of the main shank portion 5. This hinged joint permits the'forwar extension 8 to be flexed downwardly but the tongue 10 by engaging the upper surface of the main shank portion 5 prevents vertical movement of said forward shank extension. 11 indicates the hinged ppintle passing through the hinge tongues ands:

In Figure 5 I have shown another modified form in which the main shank 5 is pro- However, when load is the outer sole of the shoe h is provided with'an overlapping vided with an opening 5 on its forward end while the shank extension 8 is provided with a tongue 10 desi ned to be passed through the opening 5 an form an elbow joint po'ssessing the functions above described.

In the forms shown in Figures 1, 2 and 5 when the outer sole of the shoe is flexed opposite the hinge joint of the shank, there is a relative longitudinal movement between the parts of the metal shank constituting the arch support.

In Figure 6, I have shown a modified form corresponding substantially to the form shown in Figures 3 and 4 in which the support is made up of three sections a, b, and 0, connected to ether in such a manner that the two forwar sections can be flexed downwardly but are substantially rigid when a load is imposed thereon at a point between the ends of the arch support.

In Figure 7, I have shown an arch support composed of three sections a, b and 0, sections 1) and'c having tongues on their forward edges and being provided with slots 12 through which pass rivets 13. These rivets permlt a longitudinal and lateral movement of the forward sections and also a slight hinging action of the forward sections relative to the heel section on account of the play between the heads of the rivets 13 and the parts which they connect together.

In Figure 8, I have shown a hinge formed by means of a loop 14, see Figure 9, which loop has its ends received in an eye 15 on the front section 16 of the arch support, there being a bent tongue 17 provided with a jog or bend, which passes throu this form, 18 is the forwarv support. In Figure 10, I have shown the heel section 19 of the arch support provided with downturned flanges 20 for receiving the hinged extension of the and a depressed portion 24, the atter co-oph eratin with the hinge; intle. I

In igure 11, I have s own a construction in which the forward ortion is formed with an eye 26 at the en if of the tongue which lies under the heel portion 27 of the support, said heel portion being rovided with a depressed portion 28 on eac side of the slot 29.

In Figures 12 and 13, I have shown the forward portion 29 as having hinged lugs 30 designed to. co-operate with the hinge lu 32 on the rear portion 34., A hinge pind tle 35 passes" through the hinge lugs and serves to hold the parts in position while flanges 36 on the contiguous edges of the parts, by contacting with each other above the hinge pintle, prevent the forward portion from be flexed upwardly;

WhatIclaimis:

1. An arch supporhfoe shoes composed of a plurality of parts hingedly connectedpintle 21. The forward extension 22 tongue 23 h the loop. In I assa together, said parts being anchored and rigidly secured to a part of the shoe on each side of said hinge connection.

2. A sectional metal arch support, the sections of which are designed to be separately secured in position between the III- ner and outer soles of a shoe, and means for connecting said sections together for flexing movement in one direction only.

3. A metal arch support for shoes comprising a main shank portion and a forward extension connected together for relativelongitudinal movement, and means for securing said parts respectively to the outer sole of the shoe.

4. A metal arch support for shoes comprising a main shank. portion and a forwardly extending portion, said parts being connected together for relative longitudinal movement, and means for anchoring each of said parts to the outer sole of the shoe, sa1d means being located .on each side of the ]01I1t between the parts.

5. A metal arch support for shoes comprising a plurality of shank portions designed to be fastened respectively to the outer sole of the shoe, said shank portions being designed to engage each other when the outer sole of the shoe is bent upwardly and placed under tension, thereby placing said shank portions under compression, and said shank portions separating whenthe outer sole is bent so as to be placed under compression.

6. A metal arch support for shoes comprising two members, one of which is designed to be anchored to the heel seat of the shoe and the other of which is designed to be anchored to the ball of the sole, said last mentioned portion being capable of movement in one direction only with respect to said anchored portion.

7. In an arch support for shoes, the combination of a shoe, its outer sole, inner sole and heel, said arch support being composed of a plurality of sections one of which is anchored to the shoe at the heel portion thereof, and another ofwhich isanchored to the ball of the shoe, said last mentioned section being movable in .one direction only.

with respect to the heel anchored portion of the support, and both portions of said arch support being located between the inshoes, of an arch support composed of sections, each of which is anchored to said outer sole, and a joint between the sections which permits flexing of said arch support in one direction only.

In testimony whereof I hereunto aflix my signature this 10th day of March, 1922.
