a in'eafio filed Ma foot of'the arch and the sole of the shoe;
to enable the combining of different kindsv or sizes of shank foreparts with different sizes or shapes of heel seats and to'accomplish all of such desirable objects in a simple and entirely practical way.
The objects mentioned are attained by cer- I tain novel features of construction, combination and relation of parts, as hereinafter described in detail and broadly claimed.
The drawing accompanying and forming part of this specification illustrates a single commercial embodiment of the invention, in, which: r
- Figure 1 is a perspective top view of a form of the new shoe shank. I
Figure 2 is a longitudinal sectional view of the same, illustrated by broken lines, its position in a shoe structure.
Figures 3 and 4 are enlarged cross sec" tional views on the planes of lines 33 and l-4; respectively of Figure 2.
One of the important new features of the invention isthe constructing of the main parts of the shank, that is, the heel seat and the forepart in two separate pieces or parts 5, 6. These are shown integrally united, substantially at the junction ofthe forward end of the heel seat with the top of the arch by a scarfed joint 7, suitable cement being employed as the uniting agent. The exact position of this joint may vary and the line of the joint may be transverse as indicated, or on an angle, dependingon different conditions. The simple transverse joint shown has proved practical, the upper forward edge of the heel seat piece and the under rearward edge of the forepart piece being similarly bevelled and these bevelled parts being secured together with the forepart overlying the heel seat.
This two-part construction makes it possible to use relatively small pieces of leather,

such as would'be wholly unsuited to forming an ordinary shoe gshank, thus rendering j available forthe' purpose, bits ofleather that are now wasted orput to profit 1c uses, and this construction furthermore enables heel seats and forcparts being blanked out separately in different siies,
and shapes and being subseq'uently united in various different combinations 'to meet particular v requirementsj A suitable. shank stifi ener inay" be einployed such asindica'ted at 8 and this serves to furtherunify the two pieces. of which the shank is made. i
It has been the practice heretofore to use the .grain side of the leather as an actual heel seat since it presents a smooth, good wearing surface. In the present disclosure, theheel seat piece is shown arranged with the grain side 9 upward and as coneaved somewhat, after the approved manner of the heel seats Attempts have been made heretofore to givethe forepart of the shank-an upward transverse curvature to fit up into the cavity of the arch in the foot, but such attempts have not been wholly satisfactory because the grainsurface of the leatherhas a tendency to flatten out and lose its transverse Another special feature of this invention is the use and arrangement of the forepart piece with the flesh side, indicated at 10, faced upwardly and skived or bevelled on the edges as atll to, give it the permanent transverse arch indicated in Figure 4-. This'transverse arch is shown as tapering out at12 into the flat tongue eX- tension 13 and this substantiallyflat tongue is indicated as extended far enough forwardly over the sole (Figure 2) to cover that point 14 atthe foot of thearch where a break in the sole frequentlyoccurs.
In forming the transverse curvature by skiving the flesh side of the leather, a permanent arch is produced on the upper side this arch actually has an elastic cushion effeet which relieves strain on the arch ca vity as well as actually supporting, the same. The
tion, said heel seat section having a pre formed heel seat cavity in the top of the same and the forepart' section having'ai preformed upwardly extending transverse arch in the top of the sa ine and the joint between the two sections being located substantially in a line of merger from the coneave heel seat to the upwardly arched cross section ot the torepart.
2. A shoe shank comprisin separately constituted sections, one a leather heel seat arranged with the grain side of the same upward and the other a leather forepa-rt arranged with the flesh side of the same upward, said parts being: shaped and united the cavity in the 'arehof the foot, the upper flesh side of said forepart being perina .nentlyarehed upwardly transversely of the same.
4. A shoe shankconiprising a leather heel seat with the grain side faced upwardly and a'leather forepa'rt arranged with the flesh side faced upwardly, saidrreversely faced leather sections having reversely bevelled end edges secured in overlapping engagement and the upper edges oi the forepart being; bevelled to impart downwardly to'the flesh side of the iorepart"an'upward transverse why V y v In testimony whereof we ourisignatures.
