A further object of my invention' is to provide arch supporting means for the human foot which shall combine the maximum of comfort with maximum support of the bones comprising the transverse arch, while at the same time creating a minimum of pressure on the plantar arteries in the Ioot,`thus effecting aminimum of interference with circulation.
A further object of my invention is. to provide a, cushioned support for the transverse arch'oi' the human foot which shall be effective particularly to aiord a rm support for the scaphoid, internal cuneiform and cuboid bones of the transverse arch. Y y

Fig. 8 is a view similar to Fig. 'I showing the Referring to the drawings, I show in Fig. l an innersole ID which preferably ismade of relatively soft material covered with al soft leather covering II stitched around the edges as shown at I2. Along the sides of the forward part of the inner sole I provide elongated, relatively thin soft pads I3 and Il which are adapted to bear' against the side of the great toe and the head of the rst metatarsal bone aswell as the side of the little toe and the head of the iifth` metatarsal bone and serve to prevent callouses from forming on the sides of said toes and the foot at said bones. Incorporated in the innersole is my irn- A very important object of my invention is to provide a cushioned support for the transverse arch of the human foot which shall be adapted to hold this arch level which is its natural posi? tion and which shall be adjustable longitudinally and as to height to adapt it to the needs ofthe particular user.
A stillurther object ofmy invention is to provide an arch support which shall be effective to' hold the foot level with a rmsupport under the cuboid bone of the transverse arch at the outer side and under the scaphoid and internal cuneiform bones at the inner sides and one which shall not pinch the arteries and thus interfere with the circulation in the foot.
A device embodying these and other features of my invention is illustrated in the accompanying drawings, forming a part `of this application Fig. 1 is a plan view of an innersole for a shoe having my imploved supporting means incorporated therein, parts being broken away;
Fig. 2 is a plan view of an innersole for a shoe having my improved sole superimposed thereon v to illustrate the diiferenoe in outline;
'Figs 3 and 4 are detailed views of small pads incorporated in the support at the sides thereof;
Fig. 5 is a sectional view taken along the line Fig. 6 is a plan view showing the skeleton of the human foot in dotted lines with my improved arch support superimposed thereon to illustrate proved arch support I6. The arch support comprises 3 sep'arate sections I1, I8 and I9, the sec tions I8 and. I9, at the sides, being generally triangular in shape, and provided with hinge vgrooves along the Iborders of said sections. The support is in the form of a pad of relatively rm mate rial such as leather or rubber, with the hinge grooves 2| and 22 cut into thematerial to aiord extra flexibility along the lines of the grooves. As
1 shown in Fig. 1, the grooves 2l Aand 22 are rela- 'tively wide with their inner sides skived to slope toward the forward portion' II. Also, the area in the forward section indicated by the line 2li is slightly hollowed out in order that the pad shall not pinch the plantar arteries in the sole of the foot and impede circulation- The forward edges of the section I1 are skived, as indicated, to reduce the height of the support under the meta- `tarsal bones, but the outer sides of the sections eral-spreading of the transverse arch, I provide a relatively soft pad 26, which is hinged to the innersole Ill alongthe side of the .arch support to provide lateral support to the scaphoid and inner cuneiform bones. Also, there is preferably incorporated in the inner sole l a heel support pad 21 which raises the outer side of the heel and is usually necessary in order to level up the heel bone and cause Vit to assume its normal vertical position. In weakened feet there is a tendency for the heel bone to roll over to the outer side.
On the under side of the innersole I0 is a pin 28, indicated in dotted lines in Fig. l, for securing the innersoleagainstiforward displacement in a shoe.
In order that the shape of my improved innersole, as compared with the usual innersole of a shoe, may be seen, I show it in Fig. 2 with the usual innersole 29 superimposed'therenn` in dotted lines wherever it departs from the outline of my innersole. It will be -seen that the parts In Figs. 6, 7 and 8, I show the relation of my improved arch support to the skeleton of the human foot. By referring to Fig. 6, it will be seen that the'section I1 provides support for the middle cuneiform and exter-nal cuneiform bones of the transverse arch and for the rearward ends of the second, third and fourth metatarsals, and
partialsupport for the bases of the rst and fth metatarsal's. Section I9 is so shaped as to af#- ford support to the internal cuneiform and scaphoid bones, while the section I`8 is so shaped as to afford support to the cuboid bone of the.
transverse arch. The grooves 2| and 22 in the support permit hinge movements between the.
sections and further aid in providing a rm grip on the. transverse arch. By referring to Figs. 7' and 8 the support afforded to the inner and outer bones of the transverse arch by the sections I8v and I9 will be further appreciated.
From the foregoing it will be seen that I have provided an improved arch support which is adapted to form an integral part of a shoe and can be removed and adjusted to accommodate the height of the transverse arch of the individual user and which fits under and affords support to the separate bones ofthe transverse arch'.
Itwill be further seen that my'improved arch supportaffords a special s upport to the side bones' of the transverse arch, leaving the inner portion" placed thereupon as are specifically departing from the spirit thereof, and I desire,
therefore, that only such limitations shallbe set forth in the appended claims.
What I claim is:
l1. A support for the transverse arch of the human foot comprising a sectional pad `with thev sections hinged together by. weakening lines and.
including two sections extending forwardly from the heel line at the sides for affordingilrm trans# verseiy level-support toztlie=ouboid, the scaphoid and the inner cuneiformbones of the arch, and
.a third section extending forwardly of the other two sections for vsupporting the rearward ends of'nll'thezmetatarsalbones.
'2. A support for the transverse arch of the hinnan foot comprising a sectional pad with the of the support relieved so as not to impede circulation, and holding the arch in a raised, level position. It will still further be apparent from the foregoing description that by reason ofthe' particular .forms of the sections of the support and by reason of the means provided for the ad'- justment of the position of the supplemental support, I have provided for the maximum yof comfort and utility to the user.
While `I have shown my invention in but one form, it will be obvious 'to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications, without sections hingedtogether by weakening lines and including two sections extending forwardly from the heel' line at the sides for affording firm transversely levellsupport .to .the cuboid the .,soaphoid and the inner cuneiformibones of the arch, a
iform bones 4of the transverse arch to afford.
lateral support thereto.
3. Ar support for the transverse arch `of 'the human foot comprising asectional pad with the sections hinged together by weakeningv lines and including two. sections extending forwardly from' the.heel line at .the sides. for affording firm transversely level supportto the ,cuboid, the scaphoid'.
:and the inner cunei'form bones of the archa 'third section extending forwardly of the other two sections for supporting the rearward ends of all the metatarsal bones, a, section bent lupwardly alongside the scaphoid and inner cuneiform bones of the transverse arch toafl'ord .lateral support thereto and relatively narrow supplementary pads disposed beneath the two sections at the sides to raise the sides of the arch higher than the central portion and relieve pressure on the plantar varteries of the foot.
'4. A support as `deiinedin claim'2 in winch .the said third section extends forwardly beneath the rearward .ends of thefmetatarsal' bones and terminates'in a thin edge forwardly of Asaid'rearward' ends.'
5. A support as defined in claim'21in whic`h 'the sections at the sides are generally 4triangular in shape', the pad being provided with 'hinge grooves along the inner borders of .said sections, andthe .central area of said pad is'slightly hollowed out the plantar ar- )the metatarsal bones, the area between said supporting portions being slightly hollowed out to free circulation in the zplantar arteries.
