SHANK STIFFNER Filed Mann 20,'1937 2 sheets-sheet 2 Patented May 23, 1939 PATENT OFFICE 2,159,602 sHANK STIFFENER Justin P. Quirk, St. Louis County, Mo., assignor to United Wood Heel Company, St. Louis, Mo., a corporation of Delaware Application March 20, 1937, Serial No. 131,983

l 2 Claims.

This invention relates to shank stiieners in shoes and particularly to means for attaching the stiffener to the heel.

An object of the invention is to provide improved means for anchoring the rear end of a shank stiffener to a heel, in such a manner as to prevent relative vertical movement between the shank stiffener and the heel while permitting longitudinal movement between the stiffener and the heel. In accordance with known practice a shank stifener is inserted between the insole and outsole of a shoe. If the outsole is extended rearwardly covering the entire bottom of the shoe, no particular fastening means is required to anchor the fastener to the heel, because the fastening members between the insole and outsole may be suicient for this purpose. But where the outsole does not extend to the full end of the heel it is esential that the stiffener be so anchored, In making the' last mentioned type, the shoe is bottomed with the outsole and the shank stiifener is put in place before the heel is attached. Accordingly this invention provides means whereby the heel may be readily inserted in place on the rearwardly exposed end of the shank stiffener, while relative vertical movement between the heel and the stiffener is prevented. The advantages of the invention will be apparent from the following detail description taken in connection with the accompanying drawings.

Fig. 1 is a view showing the relationship between ashank stiffener and a heel embodying this invention;

Fig. 2 is a sectional view of a shoel with the stiffener in place:

Fig. 3 is a section on line 3-3, Fig. 2;

Fig. 4 is a perspective view of a fastening or anchoring member shown in combination in the preceding gures; and

Figs. 5, 6, 7 and 8 are views corresponding respectively to Figs. 1, 2, 3 and 4, but illustrating a modication of the invention; Fig. 5 showing the relationship between the shank, the fastener and a heel, Fig. 6 being a sectional view of a shoe showing the combination embodying the improvement, Fig. '7 being a section on line 'I-'I in Fig. 6, and Fig. 8 being a perspective View of the modified form of fastener or anchor.

In the embodiment shown in Figs. 1, 2, 3 and 4 a shank stiffener I is positioned between an insole 2 and an outsole 3, which are secured to an I upper 4. A heel 5 is employed which, as shown in (Cl. 3G-76) the rear end of the shank stiiener I, permitting the insertion of the rear end of the fastener endwise between the bridge and the upper'surface of the heel, by permitting relative longitudinal movement between the fastener and the heel, while preventing relative vertical movement.

The fastening member 6 comprisesa plate 1 having integrally at each side downwardly extending prongs 8 which engage in the material of the heel.

As clearly shown in Fig. 2 the outsole 3 does not extend to cover the heel portion: of the upper. Thus it will be obvious when the upper, insole and outsole of a shoe are assembled with the shank stiiener I in place, the rearend of the stiffener will extend outwardly beyond the rear edge of the outsole 3. The outsole may stop at the edge of the heel, as specifically shown in Fig. 2, or it may extend rearwardly under a portion of the heel, as shown in my Patent No. 1,857,475, granted May 10, 1932. In either case, however, the rear end of the stiffener will extend beyond they rear edge of the outsole.

In order then to form an anchor between the heel and the shank stiffener, the fastener or bridge member 6 is driven into the upper surface of the heel until the plate 1 is spaced and arranged with reference to the top surface of the heel topermit the insrtion endwise of the rear end of the s-tiiener. In placing the fasteningmember 6 on the heel seat, a gauge member may be inserted. beneath the plate I to form a proper space which, after the prongs 8 are driven into place, will be removed.

vThe details of construction of the shoe, such as fastening means or members between the upper, the insole and the outsole, and between the heel and the upper, are not shown because these matters which may be left to the selection of the art and the particular selection is not important to the practice of this invention.

In the embodiment illustrated in Figs. 5 to 8 inclusive, parts shown which are like those shown in the preceding gures are given the same respective reference numerals. In this case, a shank III is employed having a bifurcated end, as best shown in Fig. 5, which provides an endwise groove or slot I I for a purpose which will be presently described. A fastening member I2 is employed which has a support, bridge or head I3 secured integrally to a pin or screw member I4, which extends downwardly and serves to fasten the member I2 to the heel and to space the bridge or plate I3 above the top surface of the heel. The rear end of the stiflener I0 is so arranged that the pin I4 of the fastener I2 will pass in the slot l I in the fastener and the fastener will be so arranged on the heel to permit the insertion of the rear of the stilener endwise between the table or bridge I3 and the heel seat.

From the foregoing description it will be apparent that the invention accomplishes its objects, that an improved combination has been provided whereby the end of a stiflener extending beyond the rear edge of an upper may be assem bled readily endwise with the heel, With the result, however, that the end of the shank stiffener is securely anchored to the heel and its displacement vertically is prevented. At the same time the iiat top or table of the fastening member doesnot tend to give any discomfort to the wearer of the shoe in which it is employed. Various changes may be made in the details of construction, within the scope of the appended claims, without departing from the spirit of this invention and parts of the inventionmay be used without the whole.

I claim:

1. In ashoe the combination comprising a heel,

a fastening device on the heel seat having a plate and engaging members integral with the plate and extending downwardly from the edges of the plate to engage in the heel and support the plate above the heel seat with a slot therebetween, and a shank stiffener having its rear end extending through said slot and rearwardly beyond the rear edge of the plate, whereby said fastening device is adapted to receive and pass the end of the stiffener while preventing relative vertical movement between the heel and the stiifener.

2. In a shoe, the combination comprising a heel, a shank stiiener, a support secured to and spaced above the heel seat providing a through space between the support and the heel entirely spanning said stiiener, the stiiener having its 'end extending through said space and rearwardly beyond the rear edge of the support, whereby said bridged space is adapted to receive and pass the rear end of the stiiener while preventing relatively vertical movement between the heel and the stiifener.
