C. H. BROWN SHOE Filed July 13, 1922 Jan. 17,'` 1928.

INVENTOR /'aw/z ws ATTORNEY Patented Jan. 17, 192s.

UNITED STATES s f v if Among the principal objects which the present invention has in view are: to prevent shoes for personal wear bending or becoming flexible under the longitudinal or s long `arch of the human foot; to decrease the weight of the material needed to insure the necessary rigidity of the above mentioned structure without diminishing the structural resistance thereof; to insure the stability of lo the service relations of the parts of the structure above mentioned; to furnish means incorporated in the shoe structure for manipulating the metatarsal arch of the human foot when wearing a shoe of the character described; to support the rear portion of the longitudinal arch adjacent the heel of the wearer; and to improve the construction of the shoe and particularly the so-called shan portion thereof.

Drawings.

Figure 1 is a side vie'w partly in section of a shoe constructed and arranged in accordance with the present invention, the section being taken lengthwise thereof.

Figure 2 is a horizontal section taken on the line 2-2 in Figure l, the superposed portions of the structure being cut away to disclose the arrangement of structural elements otherwise covered thereby.

Figure 3 is a cross section, the section beintaken as on the line 3 3 in Figure 2.

igure 4 is a section taken as on the line 4--4 in Figure 2.

Figure 5 is a detail view in perspective showing schematically the shank liron and parts associated therewith for manipulating the members of the metatarsal arch and for anchoring the iron in service relation to the general shoe structure.

Description.

The present invention more specifically relates to an improvement on the structure disclosed in the Patent No. 1,249,318 issued to me vunder date of December 11, 1917, for improvements in shoes, to which patent cross 4reference is here made, and more particularly to the introductory portion of the specification thereof as contained in paragraphs 3, 4, 5 and 6, extending from vlines 13 on page 1 of the specification in said patent, to line 55 on page 2 thereof.

As seen in the accompanying drawings the shoe is rendered substantially rigid, between the sole 10 and heel 11 of the shoe, and more Application med July 13,

SHOE.

1922. Serial No. 574,705.

particularly between the point indicated by the numeral 12 and the heel l1. The point. in the shoe indicated by the numeral 12 is that corresponding with the inner joint of the great toe of the wearer, it being the purpose and intention that the shoe or sole 10 thereof, shall bend on the line coincident with the said joint. To this end a shank iron is provided with a. horizontal inward extension 13 and an inclined outer extension 14. These sections are seen best in Figures 2 and 3 of the drawings. i

To strengthen the shank iron and to augment the resistance to any bending effort offered by the inclined extension 14, I form y a preferably pendent ridge 15. This construction permits me to use alighter ma terial in the construction of the shank iron than would otherwise suffice.

As disclosed in the patent above referred to, the shank iron is further provided with anchoring spurs 16 which enter the insole 17 and parts associatedtherewith to maintain the service disposition of the front end of the shank iron. At the rear eXtremty of the shank iron a perforationl 18 is provided to receive a fastening member or members such as `the tack 19.

By employing the spurs 16 and the tack 19, it is obvious the shank iron is securely held in the Vshoe structure.

It will be understood that the last employed in building shoes constructed and arranged in accordance with the present nvention, is preferably provided with a pocket or depressed portion adapted to receive the protuberance 20 molded in the insole 17. When molding the protuberance 20 in the insole 17, a recess is formed at the under side thereof adapted to recieve a pad 21 which is secured thereto by any suitable adhesives. When employing a canvas reinforcing cover 22, this is overlaid and secured to the insole 17 and the pad 21 in the manner shown bt in Figure 2 of the drawings. It will be understood, however, that the insole may be otherwise formed to provide a thickened area where the pad is shown in the present drawings.

It will be understood that when constructing shoes in accordance with the present invention the insole is preliminaril molded to form the protuberance 20 with te pad 21 therein seated, and covered by the canvas cover 22.

The insole is applied to the last and is los j edge of er of the structurally connected with the up efore the shoe, ready to receive the sole 10 `shank iron is placed. The rearward edges sion 24, at. the edges of which are the spurs 16, as best. seen in Figure 5 o!" the drawings.

Secured to the underside of the extension 24 is a skived tab 25, the edge whereof extends beyond the extension 24 and is connected to the insole and the canvas cover 22 thereof. Coincident with the attachment ot the tab Y25 with the insole above. referred to. the spurs 16 are driven or imbedded in the pad 21 and insole 17, 'the iron having been properly the said pad 21 against which the shoulders 23 are abutted. The sole 10 is now o'verlaid'upony the insole, and the shank iron, and to 'a welt provided therefor the 'said sole is secured.

It will be seen that coincident with the metatarsalV arch .of 'the foot, the present structure has provided an added thickness resting on the sole 10 embodying the tab 25, theextension 24 lof the shank iron, the pad 21, and the protuberance 20 of the insole 17. When the foot is nowplaced in the shoe the flesh of the foot below the said arch rests directly upon the protuberance 20, and when the weight of the foot is thrown thereon as in walking, the pad serves tosupport the arch and to prevent the usual contraction thereof as whenforced into a circular or gutterlikel recess as results when wearing shoes of usual construction. As a direct result of this support the articulated bony structure forming the said arch is opened' and caused to function, thereby promoting circulation of the blood 1n this portion of the foot.

It will be noted by reference to Figures l and 2 of the drawings that the inclined extension 14.- of the shank iron terminates at a point forward of the breast of the heel 11. The shape of the heel of the wearer and the longitudinal arch carries on the inside of the foot back beyond the breast of the heel. It is to support the section of the longitudinal arch above the heel and back of the breast thereof that I insert the triangular ad 26 which is molded to correspond with t e lift of the extension 14. It will be understood that the edges ,of the pad 26 are skived or out away so that the surface adfades or blends into the under surface o the insole so located by means of the upstanding as to avoid forming a ridge or wrinkle 1. In a shoe as characterized in combination an insole molded to form a projection extending upward in lthe shoe in the region ot the nietatarsal arch ot' the foot. a pad permanently attached to said insole' beneath thc molded section to support said molded scction in service, the rear edge of said pad forming a substantial rearwardly opposed shoulder to conform with a shoulder of a shank iron for supporting said pad and insole, and a shank iron having at its forward enda relatively fiat extension having rearwardly extending shoulders intersecting'at an obtuse angle or registering said iron in relationto said pad and projection.

2. In a shoe as characterized in combination an insole molded to form a projection extending upward in the shoe in the region of the metatarsal arch of the foot a pad permanently attached to said insole neath the molded section to support said molded section in service, the rear edge of said pad forming a substantial rearwardly opposed shoulder to conform with a shoulder of a shank iron for supporting said pad and insole, a shank iron having at its forward end a relatively flat extension having rearwardly extending shoulders intersecting at an obtuse angle for registering said iron in rel-.ition to said pad and projection, and meansy provided in said extension for attaching the same to said pad and projection.

3. In a shoe as characterized in combination an insole molded to form a projection extending upward in the shoe in the region of the metatarsal arch of the foot, a pad permanently attached to said insole beneath the molded section to support said molded section in service, the rear edge of said pad forming a substantial rearwardly opposed shoulder to conform with a shoulder of t shank iron-for supporting said pad and il*` sole, a shank iron having at its forward en a relatively flat extension having rearwardly extending shoulders intersecting at an obtuse angle for registering said iron in relation to said pad and projection, and means provided in said extension for attaching the same to said pad and projection, said means embodying anchorin spurs upturned at the forward edge of Sai extension for insertion into said pad and insole structure.
