14: Claims.

This invention has relation to a shoe.

An object of the'invention is to provide a. shoe which will be of novel andimproved construction.

A further object is to provide a shoe which will include. a construction and arrangement for supporting the arch of a person's foot and wherein will be incorporated desirable and improved features and characteristics.

And a further object is to-provide a shoe which will include a new and improved construction and arrangement applied to the bottom of the shoe at a location forwardly of the heel and in protecting relation to the arch of the foot of a wearer.

With the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible as long as within the spirit of the invention and the scope of the claims which follow.

With respect to' Figs. 1' to 5 of the drawings and the numerals of reference thereon, Illdenotes a shoe, as customarily worn by football players, having cleats ll on the sole l2 and cleats ['3 on the heel it of the shoe, and i5 represents an attachment device for said shoe, applied to the sole and heel between the cleats H and I3, beneath the. arch and in protecting relation to the foot of a wearer.

A metal plate 16 of the attachment device it,

secured, as by screws IT, tothe' sole and heel ofv the shoe between the cleats II and I3, integrally or rigidly supports'spaced apart, downwardly extending flanges l8, l8 situated in verticallyalined relation with the opposite side edges of the sole l2 and heel l4 and terminating at their lower side edges at elevation considerably above the lower ends of said cleats H and It. In the disclosed embodiment of the invention, the lower side edges of the spaced apart, downwardly extending flanges l8, l8, terminate in a plane substantially parallel with the plane of the sole l2 and the heel it of the shoe.

A compressible rectilinear pad l9, which desirably can be constituted as sponge rubber, is adapted to be-situated between the spaced apart, downwardly extending flanges l8; IS in such manner that its upper surface 26 is engaged against the lower surface of the metal plate It, its opposite side surfaces 21, 2| are contiguous with internal surfaces of said spaced apart, downwardl'y extending flanges l8, it, its opposite end surfaces 22-; 22 are in vertically alined relation with the opposite ends of said metal plate l8 and in adjacent relation to cleats H and i3, respectively, and its lower surface 23 is situated in aplane disposed considerably below the plane ofthe-lowerside edges of the spaced apart, downwardly' extending flanges l8, l8 and slightly above and substantially inparallel relation with the tion to its upper and lower surfaces and having their lower ends 25 terminating in adjacent relation to the lower surfaces 23. In the illustrated embodiment of theinvention thepockets or concavities 24 are of cylindrical configuration, and

each pocket or concavity 24 more or less loosely contains a compression coil spring 26 having its lower end' engaged against a metallic disc 21 in the bottom of the corresponding pocket or concavity and its upper end adapted to be engaged against the lower surface of the metal plate It.

Each metallic disc 21 includes an aperture 28 therein for passage of air.

Spaced apart, transversely extendin tubes 29, 29 of rigid material desirably metal, imbedded in said compressible rectilinear pad and open at their opposite ends to the opposite side surfaces 2!, 2i, are for snugly receiving cross rods 36, 38, which also desirably may be of metal, for securing the compressible rectilinear pad to the downwardly extending flanges Hi, It of said metal plate It. The transversely extending tubes 29, 29 are adapted to be alined with spaced apart openings 3!, 3| through said downwardly extending flanges, and each cross rod 30 is adapted to be snugly inserted through alined openings 3i, 3! in the downwardly extending flanges, as well as through the transversely extending tube 29 at the corresponding end of said compressible rectilinear pad. Each cross rod 30 has a retaining head 32 on one of its ends and a transverse aperture 33 in its opposite end portion adapted to removably receive a transverse retaining pin 36. The retaining heads 32, 32 and the retainingpins 34, 34 desirably will be in contiguous relation with the exterior surfaces of the downwardly extending flanges 18, 18, about as disclosed in Fig. of the drawing, when the cross rods 35), 38 are in their inserted positions, and the opposite ends of the transversely extending tubes 29, 29 will be in contiguous relation with the interior surfaces of said downwardly extendin flanges when the compressible rectilinear pad i9 is in secured position. The spaced apart, transversely extending tubes 29, 29, are, as shown, in an upper portion of said compressible rectilinear pad in somewhat spaced relation to its opposite end surfaces 22, 22, respectively, and in clearing relation to the pockets or concavities 24, and the openings 3!, 3i for receiving the cross rods 30, 39 are at about the midwidths of the downwardly extending flanges l8, it. It will be apparent that the compressible rectilinear pad is will be retained against transverse movement relative to the shoe by the downwardly extending flanges i8, i8 and against longitudinal movement relative to said shoe by cooperative action of the cross rods 3G, and the transversely extending tubes 29, 2s.

When a wearer of the shoe is standing so that the lower ends of the cleats II and 13 rest on top of a supporting surface, such as the ground, for said shoe, the lower surface 23 of said compressible rectilinear pad 19 will be in spaced relation to the shoe supporting surface, and when said cleats ii and it become imbedded in said shoe supporting surface a distance equal to a measurement representing the distance said lower surface 23 is spaced from the lower ends of the cleats H and 13, the compressible rectilinear pad itself will be in engagement with the shoe supporting surface. The construction and arrangement will be such that the compressible rectilinear pad and the compression coil springs 26, together, and without aid of the cleats, will withstand the weight of a standing wearer without collapsing of said compression coil springs, and also such that the compression coil springs will become collapsed, to greater or less extent, when the wearer walks, runs or jumps. For heavier individuals, the compression coil springs 26 will be made stronger, or more powerful, than for lighter individuals.

The attachment device functions as an arch supporter and protector for the foot and ankle of a wearer both when the collapsible rectilinear pad 19 is spaced from the shoe supporting surface and the coil springs 26 are under normal compression and is engaged with the shoe supporting surface and said coil springs are under additional or abnormal compression due to the weight of a wearer, and when said compressible rectilinear pad I9 is placed under additional or abnormal compression so that the coil springs are caused to become collapsed, reaction of said coil springs is upwardly directly beneath the arch of the foot in amount commensurate with the extent of compression of the coil springs. Thus, upward reaction against the arch of a wearers foot is calculated to counteract in substantial amount tendency toward downward movement or action of the arch of the foot of a wearer when he walks, runs or jumps. When under normal compression, as well as when under additional or abnormal compression, the coil springs 26 function to have tendency toward maintaining the sole l2 and the heel I l of the shoe substantially in a single plane.

The attachment device, while offering no interference to proper functioning of the cleats II and i3, prevents said cleats from becoming imbedded to excessive extent in a supporting surface, such as the ground, for the shoe. Hence, said attachment device is insurance against stumbling as sometimes occurs by reason of football shoe cleats as heretofore employed becoming unduly imbedded in the ground.

Referring to Figs. 6 to 9, 40 denotes an ordinary shoe, and M represents a construction and arrangement, for the same general purpose as the attachment device l5, beneath the arch and in protecting relation to the foot. The entity 4! is situated between a sole #2 and a heel 43 cf the shoe, and said sole and heel are composed principally of cork. More explicitly, there is an insole M to which an upper, above the insole, and the sole 42 and the heel 43, below said insole, are secured in such manner as to provide a usual concavity 45 between said sole and heel.

A compressible rectilinear pad 48, of sponge rubber as disclosed, is situated and suitably housed in the concavity 45 in such manner that its upper surface is engaged against the lower surface of the insole M, its opposite side edges are adjacent and Within the confines of the opposite side margins of the shoe, its opposite end surfaces 41, 4'! are in contiguous relation with the sole 42 and the heel 33, respectively, and its lower surface 43 is situated substantially in the plane of the lower surfaces of the cork portions of said sole and heel. The opposite sides of the compressible pad 46, and the opposite sides and ends of the sole and heel, are enclosed by covering material 49, and a cover strip extends along the lower surfaces of said compressible pad and said sole and heel throughout the whole of the areas of the compressible pad and sole and heel. The construction and arrangement will be such that all of the parts of the shoe are retained together in a unitary structure.

The compressible pad 46 is cut away to provide spaced apart openings 5!, five as shown, extending thicknesswise through said compressible pad substantially in perpendicular relation to the insole M. Each opening 5| more or less loosely contains a compression coil spring 52 having its lower end engaged against the cover strip 50 and its upper end engaged against said insole.

When a, wearer of the shoe is standing, the lower surface of the cover strip 50 beneath the compressible pad 46 will be in slightly spaced relation to the shoe supporting surface, and when the wearer walks or runs said lower surface of said cover stripbeneath said-compressible pad may-or. may not becom'e: engaged with the shoe supporting surface.- The construction and are rangement will be such that the compressible pad". 46 and: the compression coil springs 52, together; and without aid from other source, will withstand theweight of a standing wearer of theshoe without collapsing of said compression coil springsand also. such that the compression coil springs will become collapsed, to. greater or less extent, whenthe wearer walks, runsor jumps. 'The construction and arrangement which: the embodiment of the invention as disclosed in Figs. 6 to 9. incorporates functions as an arch supporter and protector forthe foot and ankle of a; wearer in the same general manner as does the attachment device it, both when thecollapsible pad 46 is not resting upon the shoe supporting surface and the coil springs 52 are under normal compression and the lower surface of the portion of the cover strip 5G beneath said collapsible pad is engaged with the shoe supporting surface and said coil springs are under additional or abnormal compression due to the weight of a wearer. When the collapsible pad 45 is placed under additional or abnormal compression so that the compression coil springs 52 are caused to become partially collapsed, reaction of said compression coil springs is upwardly directly beneath the arch of the foot in amount commensurate with the extent of compression of the coil springs. Asin the instance of the football shoe, upward reaction against the arch of a wearers foot is intended to counteract in substantial amount tendency toward downward movement or action of the arch of the foot of the wearer when he walks, runs or jumps. When under normal compression, as well as when under additional or abnormal compression, the coil springs 52 function' to have tendency toward maintaining the sole 42 and the heel M of the shoe substantially in a single plane.
