ARCH SUPPORT FOR FOOTWEAR original Filed May 29, 1930 Patented May 9, 1933 ramas? STACY M. NICKERSON, F NEWTON CENTER, MASSACHUSETTS ARCH SUPPORT FOR FOOTWEAR Application filedMay 29, 1930, Serial This invention relates to areh-su1i porting means useful in remedial treatment of varin ous anatomical weaknesses or defects of the human foot.

The invention is embodied in an arch support which includes a permanent insole and a resilient sheet metal shank piece supported by the top surface of a portion of the insole and having a resiliently yielding top surface suitably diversified to adapt it to act as a remedial or corrective support for the shank portion of a foot bottom, means being provided for interchangeably locating diiferently formed and characterized shank pieces in a. predetermined operative position in a shoe, so that a salesman in a shoe store, or the own-A er of a shoe, may combine with the shoe such forms of remedial or corrective shank piece as may be required.

Of the accompanying drawing forming a part of this speciiication,

Figure 11 is a View similar to Figure 1, showing another embodiment of the invention.

Figures 12, 13 and 14 are enlargements of a portion of Figure 11, showing modifications.

The same reference characters indicate the same parts in all of the figures.

My improved arch support includes the heel portion and. the curved shank portion of the permanent insole 12 of a shoe, a curved shank piece 13, of resilient sheet metal, preferably steel, having any desired remedial or corrective form as toits top surface, and a curvature more abrupt than that of the top surface of the curved shank portion of the insole, so that when the ends of the shank piece 13 bear on the insole, as indicated by Figures 1, 7, 8 and 11, the maj or portion of the shank piece is free to yield to foot pressure, its resistance to such pressure `depending on the resilience of the shank piece. y

I provide means, which may be variously embodied, for releasably confining the shank piece in the shoe, so that dierent shank pieces, having different characteristics as to resilience or pressure resistance, and remedial or corrective form, may be used interchangeably, said means being adapted to confine the shank piece in a predetermined operative position, causing the end portions of the shank piece to bear on portions of the top surface of the insole at opposite ends of the curved shank portion thereof. The curvature of the shank piece 13 is such that its major portion is spaced above and movable toward and from the shank portion of the insole, as indicated by Figures 1, 7, 8 and 11. 85

The top surface of the shank piece may be variously diversified to impart thereto a remedial or corrective form.` For example, the top surface may be curved orosswise, as shown by Figures 5 and 6, to provide an upwardly 90 curved wing 13a at one longitudinal edge and between the end portions of the shank piece.

rlhe confining means employed enables any one of a plurality of differently characterized shank pieces to be located in an operative position, either by a shoe salesman or by the wearer of the shoe.

In the preferred embodiments of the invention shown by Figures 1 to 10, the confining means includes a fiexible top or sock layer 14, bearing on the top surface of the shank piece and conformable thereto by foot pressure. Y

rlhe top layer 14 is formed to bear fon the bottom surface of that portion of the foot which includes the heel, shank and ball thereof, and is secured at its forward end to the fore portion of the insole, so that its rear end may be displaced upwardly to permit the insertion and removal of the shank piece.

The top layer may be formed separately from the insole and secured thereto by forward end connections provided either by stitching or cementing its forward end to the fore part of the inner sole, as indicated by Figure 1, 15 designating a cement connection.

The forward end of the top layer 14 may be secured to the fore part of the insole bj a separable forward end connection including a member 16, fixed to said forward end, and a complemental member 17, fixed to the inner sole. Said members may constitute the stud and socket members of a well-known snap fastener, or they may be otherwise organized.

The rear end of the top layer 14 may be separably secured to the heel portion of the insoleby similar members 16a and 17a, as shown by Figures 1 and 7, said members being shown enlarged by Figure 4.

The top, layer 14 may be integral with the insole and formed by,l horizontally splitting the sole from its heel end to its ball portion, as shown by Figure 8. In this embodiment the forward end connection is provided by the substance of the'sole at the forward end of the split, and the fastener member 16a is l'iXed to the heel end of. they shank piece,xas best shown by Figure 9.-

The shank piece 13 may be releasably secured to the top layer 14 'by fastener members 19, similar to the members 16 and 16a fixed to the top layer and complemental members 2() on the shank piece, the members 20 being provided by apertures or holes in the shank piece receiving the members 19.

When the top layer 14 is swungupward, the shank piece may be conveniently engaged therewith when the top layer is moved to its operative position, the shank piece 13 is operatively confined in position to afford a corrective or remedial support for the foot.

The equipment may include aset of shank pieces 13, each characterized differently from the others, for` example, by the form of their vand separated therefrom, and` top layer supporting surfaces, and by the thickness of the metal and its degree of resistance to downward pressure of a foot on the top layer.

In the embodiments shown by Figures 1 to 7 the topv layer 14 is considerably longer than the shank piece 13, so that the ends of the top layer project from the ends of the shank piece, while in the embodiment shown by Figures 8 and 11, the top layer and shank piece are of substantially the same length.

It will now be seen that the top layer 14, the described forward connections between said layer and the fore part of the insole, and the described connections between the top layer and the shank piece, constitute an embodiment of means adapted to releasably confine the'shank piece 13 in a predetermined operative position, and that said means may or may not include rear end connections,

such as themembers 16a and 17a.A layer 14 and the shank piece 13 may be separably connected by the engagement of a fastener member, such as a tack 25, (Figure 3a) engaging an orifice 20 in the shank piece 13, the inner end of the member 25 being clinched on the under side of the shank piece. The

`The top `1nember 25 is capable of being used only once,

and may be conveniently engaged with and withdrawn from the shank piece by a shoe salesman or the shoe wearer, another member 25 being employed when another shank piece is to be connected with the top layer. l am not therefore limited to separable members 19 of the snap fastener type.

Figures 11 to 14 show a simple embodiment of the invention in which the shank piece, here designated by 130, is releasably maintained in a predetermined operative position by means including a fastening member connecting its heel,.end portion with the heel end of the insole. Said fastening mem ber maybe a headed stud 26 (Figure 12), a tack 27 (Figure 13), a screw 28 (Figure 14), or one or more prongs 29 (Figure 11) integral with the heel endiof the shank piece. Either of said fastening members is adapted to anchor the shank piece against endwise displacement in the shoe, and to anchor the heel end of the shank piece against edgewise displacement. The bearing of the forward end portion of the shank piece on the opposite sides of the shoe upper, or on the forward end connection of a top layer 14 with the insole, may be relied on to prevent the shank piece from swinging edgewise at its forward end portion.

It will be seen that my invention provides an arch supporter adaptable to foot arches of different heights and shapes by using differently curved and formed shank pieces, and to foot arches requiring yielding support of varying resistance to downward pressure, by providing shank pieces of different thickness and stiffness. In aggravated cases of fallen lso arches a stronger support is required than in milder cases. The top layer element 14 may constitute a permanent part of the shoe and may be temporarily supported directly by the rear portion of the insole, to permit the use of the shoe without the shankpiece 13, until the need of the shank piece becomes apparent, the top layer occupying an inconsiderable space in the shoe, so that a shoe intended for use with a complete arch support embodying the invention does not have to be larger than the size required if the shank piece is not used. When the shoe is used without the shank piece, the rear portion of the insole having orifices 22 will receive the fastener member 19. i

Then the top layer 14 is made as a separate part as shown by Figures 1, 2 and 3, it may be supplied with the shank piece 13 as an article of manufacture to be applied to an otherwise completed shoe.

I claim:

1. An arch support for shoes comprising a v permanent insole, a curved shank piece of resilient sheet metal having a remedial or corrective form anda curvature more abrupt than that of the top surface of the shank portion of the insole, and means releasably confining said shank piece in a predetermined operative position, over the shank portion of the insole so that different shank pieces may be used interchangeably in a predetermined position relative to the insole, the end portions of the shank piece bearing on portions of the top surface of the insole at opposite end portions of the shank thereof when the shank piece is confined, the curvature of the shank piece being such that its major portion is spaced above and movable toward and from the shank portion of the insole.

2. An arch support for shoes comprising a permanent insole, a curved shank piece of resilicnt sheet metal having a remedial or corrective form and a curvature more abrupt than that of the top surface of the insole, a flexible top or sock layer covering and supported by the shank piece, and connected at its forward end with the fore part of the insole, separable holding down connections between the rear end of the top layer and the heel end of the'insole, and separable connections between the top layer and the shank piece permitting differently formed shank pieces to be applied interchangeably to the top layer when the latter is raised, said top layer and connections constituting means releasably confining the shank piece in a predetermined operative position, causing the end portions of the shank piece to bear on portions of the top surface of the insole at opposite end portions of the shank thereof, the curvature of the shank piece being such that its or portion and the top layer are spaced above and movable toward and from the shank portion of the insole.
