SHOE

Filed Feb. 24, 1930 {ima/4 Patented'feb. 16, 1932 UNiTED STATES PATENT oFFlcE ANTHONY l. PCX, OI' DUBUQUE, IOWA, ASSINOB T0 B. FIEKENBROCK & BOIB mum, F DUBUOUE, IOWA, A CORPORATION OF IOWA appunti ma rebruny a4, mo. semi 11. nam.

This invention relates to improvements in shoes and more particularly to a shoe having a resilient longitudinal arch sup ort secured to the upper surface of the inso e adja- 5 cent the inner margin of the shoe. The present invention is an improvement in the construction shown in my coendin application, Serial No. 426,559, filed Fe ruary 7, 1930.

1o The object of the invention is to provide a shoe with a longitudinal arch support made of resilient material such as sponge rubber or neumatically inflated rubber.

nother object is to so construct the arch ort that it will efliciently support the hig est part of the arch of the foot, that is, the part adjacent the inner margin of the foot; and that it will not spread outwardly or alter the general contour of its bea-ring surface when pressure is applied to the arc support.

In the drawings Fig. 1 is a top lan view of an insole and leather covering t erefor, having secured to the top of the insole an arch support embodyln my invention, the leather cover begvbro en away to show the arch support.

sup

is a transverse vertical section of a shoe embodying my invention, the same be ing taken on the glane indicated by the dotted lines 2 2 of ig. 1.

Fig. 3 is a view similar to Fig. 2, showing a modified form of arch sup ort.

Fig. 4 is a side elevation o an insole and arch support embodying my invention, as the same appear when looking toward the inner side margin.

In that embodiment of my invention shown in the drawin 10 indicates a conventional outer sole osa shoe, 11 the leather uppers, 12 the lining for the uppers, 13 a conventional inner sole, 14 the welt, and 15 a leather covering for the insole. These lpgrts are secured together in a manner well own in shoe construction.

Between the inner sole 13 and outer sole 10, extending longitudinally of the shoe adjacent the margin at the outer side of the shoe is a substantially rifid arch support, preferably in the form o a metal plate' 16 secured to the under side of the insole 13. The space between the inner and outer soles not occupied b the rigid arch support 16 is filled with ii ling material 17.

Adjacent the inner margin of the insole, and extending longitudinally of the shoe, and under the arch of the foot, lis a resilient arch support 18 preferably made of sponge rubber. It is cemented to the inner sole 13 and is highest directly under the arch of l 559, filed February 7, 1930.

One of the novel features of improvement upon the structure shown in said application consists of a side support for the flexible arch which will now be described.

A relatively thin, stiff piece of material 20 having a substantiall straight lower margin for contacting withI the top surface of the edge 21 of the insole, and having a curved upper margin 22 tapering downwardly at each end toward the lower margin, is cemented to the side of the arch support 18. The outer side 23 of the arch support 18 and the relatively stiff side support 20 are con-v cave longitudinally and are inclined downwardly and inwardly from their top margins toward their line of connection to the lnsole adjacent the inner margins of the shoe.

After the side support has been cemented to the resilient arch support, the latter is cemented to the upper surface of the insole and thereafter the leather covering 15 may be placed over the arch and insole. Without the side member 20 for supporting the overhanging, inclined side surface 23 of the arch support 18, said arch support would be apt to yield unduly under pressure and would be forced downwardly and outwardly to such an extent that considerable of its supporting qualit for the highest part of the arch ofthe floot might be lost. With `2 l nemen the side support 20 rst secured to the resilient arch 1 .in the manner shown, the high' est portion of the arch of the foot is well sunplported and the tenden to displace the ient material toward e outer of the inner side of the shoe is avoided. construction holds the top surface of the arch support as intended, with its highest portion adjacent the margin and ually 1 slo ing toward the toe, heel and si e.

lthough the addition of a side saulpport 20 is a detail of construction, it is a v uable improvement in the reparation of a shoe having a resilient arc secured to the inside of the shoe above the insole. v

In Fig. 3, a modified form of resilient arch has been shown. It comprises a flexible casin 24 preferabl made of rubber neumatica ly inflated. ts shape is simi ar to the arch support 18 made of sponge rubber and it is also provided with a relatively stiff side support 20 such as described in connection with Figs. 1 and 2.

Obviously, changes 'in details of construc- 25'tion may be made without de arting from the scope of my invention, an I do not intend to be limited to the precise' form shown and described, except as pointed out in the ap ended claims. 3 clamz Y 1. In a shoe comprising an insole, outer sole and uppers secured to ther, a resilient arch support secured to t e upper surface of the insole, extending longitudinally of i the sole under the arch of the foot adjacent the mar of the inner side of the shoe, the outer si e surface of said arch support being concave longitudinally and incllned downwardly from its top margin toward the in- 40 sole, a side member made of relativelysti material, shaped complemental to the side surface of said support and cemented to said support, and a leather cover extendin over the top and sides of the insole, the arc supl port and side support for the arch.

2. A shoe comprising an outer sole, an inner sole, leather u pers, an arch support made of sponge rub r located on the inner sole adjacent its outer margin along the inner longitudinal side of the inner sole, a relatively stiff upright member secured to the vspon e rubber support along its concave outer si e surface, and a cover extending over the top of the inner sole and arch su port and downwardly adjacent the relative y stiff member, between the inner sole and the 4 uppers of the shoe.

In testimony that I, claim the foregoing as m invention, I aix my signature, this w 21st ay of Februal, 1930.
