SHOE SHANK Fie Nov. 29, 1926 Patented May 7, 1929.
UNITED STATES PATENT OFFICE.
.TOl-IN E. SORENSON, 0F LYNN, MASSACHUSETTS, ASSIGNOR TO JOHN L. SHEVENELL AND HELMER Gr. JEEPI-ISON, TRUSTEES, 0F MASSACHUSETTS.
Sl-IOE SHANK.
Application filed November 29, 1926. Serial No. 151,430.
My invention relates to a metal shank adapted to be secured in the arch of a shoe lduring` the process of manufacture and is particularly intended as an improvement on the type of shank disclosed in the patent to 1tilinchell No. 1,447,001, dated February 27, 1923. rfhat shank coinprises a piece of struck up metal arched longitudinally and provided with a groove running lengthwise thereof, but terminating` short of the extremity to provide flat end portions. Teeth struck up from the end portions are provided for securing the shank to the leather. i
In the manufacture of turned shoes the metal shank is first applied to a leather stiffener and this stiffener is inserted into the shoe, after it has been turned, and extends from the heel of the shoe to the ball line. Some means must be provided for securely holding the leather shank piece and its attached metal shanh in place in the shoe While it is being worn. Various means have been utilized With this end in view but none of them are as simple to apply or as securely anchor the leather shank in position .in the shoe as docs mine.
in order that the invention may be more clearly understood, reference is had to the accompanying` drawing in Which Fig. l is a longitudinal section of a shoe showing the metal shank in position.
Fig. 2 is a plan view of the metal shank.
Fig. 3 is an elevation of Fig. 2.
Fig. a is a section on the line et-l of Fig. 3.
The metal shank comprises a strip of cold rolled metal having a relatively deep-groove l, running` longitudinally of the body of the shank but ternina'ting short of the ends whereby there are provided flat end portions 2 and 3. Struck out from the end portion 9. are a pair of teeth 4 and struck out from the end portion 3 are a pair of teeth 5.
In order to prevent the shank from cutting` into the overlyinp,` leather, the sides of the groove l may be flared outivardly to provide substantial areas of contact such as, by means of flanges 6 running either partly or the Whole length of the shank.
Struck out of the body of the shank along the sides and intern'iediate its end portions are a pair of integral teeth 7.
The shank iron having' already been ap plied to the leather shank 8 by driving the teeth 4 and 5 thcreinto, the assembled piece is then placed inside the turned shoe in proper position and the teeth 7 driven into and elinched on the outer sole 9. In this manner, the leather shank S is securcly held in position against twisting or sliding in the finished shoe.
While I have disclosed the integral clint-hilig teeth 7 in connection with the particular form of shank disclosed in the Wincheli patent, it is apparent that the integral intermediate teeth could be used with modified forms of the said shank.
I claim:
1. A shank iron for turn shoes comprising a strip of malleable struck up metal curved longitudinally and provided with a groove terninating short of the extremities of the strip to provide flat end portions, integral teeth in the end portions adapted to be driven into and clinched in a leather shank and an integral tooth intermediate the end portions adapted to be driven into and clinched in the outer sole.
2. A shauk iron for turn shoes having` clincl'iing teeth in its end portions for attachment to the under side of a leather shank and a pair of integral intermediate clinehing teeth for attachment to the outer sole of a shoe to attach the stilfener to the sole.
3. A shank iron for turn shoes having` clinchiug teeth :in its end portions for attachment to the under side of a leather shank. the said iron being curved longitudinally and pii'ovided with a groove ferminating` short of the extremities of the strip to provide flat end portions, and a pair of integral clinching` teeth interinediate the end portions and struck out from the side of the shank and adapted to be driven into and olinched in the outer sole.
4. A shank iron for turn shoes having` clinching teeth in its end portions for attaclu ment to the under side of a leather sh ank and a clinching tooth intermediate the end portions for attachment to the outer sole of a shoe to attach the stiffener to the sole.
5. A shank iron for turn shoes eomprsng a strip of malleable struck up metal curved longitudinally and provided with it groove terminating short of the extremities of the strip to provide fiat end portions, fastening my hand.
JOHN E. SORENSON.
