RICHMOND SHOE SHANK SUPPORT Filed March 24, 1928 gwmantoz Samue/ R c/rmand (1 ttozmq in theouter sole and metal shank Patented Sept. 15, 1931 UNITED STATES PATENT OFFICE SAMUEL RICHMOND, OF BATAVIA, OHIO, ASSIGNOR TO TI-IE EDWARDS MAN UFAC'IUR- ING COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO SHOE SHANK SUPPORT Application filed March 24, 1928. Serial No. 264,392.

This invention relates to an improved form of metal shank support for use in arch supporting types of Womens shoes and has for an object the provision of a support of this kind which eliminates the necessity for supporting or padding the space between the insole and outer sole at the forward end of the arch.

Another object is to provide a device of this kind which resiliently retains the insole of a shoe in spaced relation to the shank metal at the forward end of the arch.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. l is a top plan view of a metal shank support of the invention.

Fig. 2 is a side elevational View of the device shown in Fig. 1, part being broken away.

Fig. 3 is a fragmental cross sectional View on line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 3 but showing a modified form of construction for the metal shank support.

Fig. 5 is a top plan View of another modified form of the metal shank support of the invention. I

' In arch supporting types of womens shoes there is employed a metal shank support which extends from the top of the heel, along beneath the arch and terminates at the forward end of the arch. The metal shank support is given any desired formation and has the outer sole of the shoe molded over it. This provides a somewhat abrupt angle for the outer sole, whilst, the inner sole must assume a relatively fiat or long curve from the heel'to' the front of the sole. It has heretofore been common practice to insert small flattened pyramidal pieces of leather or other material in order to suitably support the insole adjacent the abrupt angle support.

As indicated in Fig. 1 the shank 6 may be suitably formed, for example V-shaped in crosssection and flat at the rear 7. The forward end 8 is formed or dished so as to provide a relatively fiat portion '9 angularly connecting at 10 and 11 with the angularly disposed sides 12 and 13 of the shank 6. The structure thus far described is typical of metal shank supports heretofore used. In the present invention a formed plate 14 is made integral with the forward portion of the metal shank support and is turned over thehollow portion 15 with the edges 16 of said plate 14 spaced slightly from the sides 12 and 13 of the shank and forward end 9 except for the integral connection 17 As shown in Fig. 1 the turned over connection 17 is between the portion 9 and the plate 14. In the modified form shown in Fig. 5 the integral turned over connection 17 is between the edge of the side 13 of the shank and the plate 14. The metal being resilientandtempered permits of a yielding limited movement between plate 14 and the remainder of the metal shank support, so that an insole resting upon the top portion of the shank and plate 14 thereof may yield slightly under the weight of a wearer of the shoe, thereby providing a smooth and slightly yielding support for the insole. The use of metal shank supports as disclosed herein eliminates the necessity for inserting and securingpieces of leather and the like in the hollow-15 as heretofore done, and provides a more durable and reliable shoe construction. p

In the modified form shown inFig. 4 the top portion 140 corresponding to the plate 14 in the previously described embodiments is formed continuous with the sides 12 and 18 of the shank, while the portion 90 is turned under and corresponds with the portion 9 of the previously described support. This modification comprises in general a practical reversal ofthe plate portion and assumes a spaced position to provide the resiliency just explained. The connection 17 may be at any of the edges of the forward portion of the shank support.

From the foregoing it will be readily apparent that the entire structure shown in any of the embodiments may be stamped from a single sheet of metal and formed to provide the essential features described and subsequently the plate portions 14 or 90 may be turned to position.

With the structures of this kind the process of manufacture of shoes of the type referred to is speeded up and greater uniformity is attained for the insole portion of the shoe. Inasmuch asa difference in the support of the insole at the front-ofthe arch is very noticeable to the wearer, it will be appreciated that superior goods are obtainable with the present device and that the yielding orvresilient portion provides comfort'to the wearer which was heretofore not attainable in ShOBs of this type.

What is claimed is:

1. An arch supporting shank metal hav ing a dished forward portion and an inte gral oppositely dished coincident plate spaced therefrom and having a restricted portion connecting therewith.

2. As a new article of ,manuffacture a metal shank supporting member having a dished portion and a resiliently mounted,

superposed, oppositely dished, integralfportion.

3. As anew article of manufacture a metal shank support for shoes having a downwardly dished forward end over. which anouter sole may be molded and an integral resilient member spaced from the dished portion.

4.'As a new article of manufacture an arch supporting shank metal comprising at its forward end resiliently spaced integral oppositely dished disk-like portions for abutment with the inner and outer soles of a shoe.

5'. An arch supportingshank metal comprising a sheet metal body enlarged at its forward end and having, a dished portion over which an outer sole may be molded and a superposed oppositely dished member integraltherewith and resiliently retained in spaced relationthereto. I

6. A shank for insertion within a shoe between the ,outsole and the insole thereof comprising an elongated ribbed body portion with an'extension b'entback and spaced from'thefront end of the body and providingaaresilient pad-shaped support.

i7; A shank for insertion within a shoe comprising an elongated body portion having an extension shaped as a pad, said pad being bent toward the body portion, and

being resiliently connected with said shank. In testimony whereof, I have hereunto subscribed my name this 9th day of March,

1928.v v SAMUEL RICHMOND.
