SHANK FOR TURN SHOES.

Application led January 28, 1927. Serial No. 164,160.

This invention relates to shanks for turn shoes.

An object of the invent-ion is to provide a metallic shank adaptedV to be secured upon the upper surface of a shoe sole and provided with improved interlocking engage-I ment therewith, whereby both longitudinal and lateral displacement' with the shank lis prevented. y l

Another object of the invention is to pro vide a novel and efficient means for strengthening the shank, and an improved connection securing the front end of the shank to the shoe sole to hold the partsl in proper relationship. n

Another object of the invention is to provide the improved shank herein disclosed,

carrying forward and improving the shank n disclosed kin my prior Patent No. 1,558,664, issued October 27, 1925.

Other objects will appear from the following description, reference being made to the drawing, in which Fig. 1 is a longitudinal vertical sectional view -of a shoe sole Vhaving my invention embodied therein.

Fig. 2 isa top. plan view of the shank.

Fig. 3 is a side elevation of a preferred form of the invention.

Fig. 4 is a cross sectional View approximately on the line 4-4 of Fig. 1V.

Fig. 5 is a cross sectional view approXimately on the line 5-5 of Fig. l.

Fig. 6 is a plan view of a'modified form of the invention.

Fig. 7 is a front end elevation of the shank shown in Fig. 6. y

Fig. 8 is a perspective view of a cushioning element which may be used satisfactorily in connection with the invention.

The improved shank shown is preferably made of sheet metal or metallic alloy. The shank is made from a plate of such material and is of such a length that its rear end rests upon the shoe'heel a considerable distance behind the breast wall of the heel and its forward end terminates approximately at the break line of the shoe sole.

In the preferred form of the invention shown in Figs. 1 to 5, inclusive, of the drawin'g, the shank comprises a heel portion 1 having a hole 2 therein; a shank portion 3` of appropriate intermediate width flaring to a widened front end portion 4, terminating approximately at theV break line of the/shoe in which the shank is embodied, and fiaring rearwardly to merger'with the heel portion 1. An integral extension5 of the' device eX- tendsrearwardly intopthe hole 2 toward the n rear end thereof, making the hole 2 approxi# mately V-shaped.y In side elevation,v the shank portion 3 is arcuate (Figs. 1 and 3),

conforming to the' shape 'of the shank or arch of the shoe in which the shank `is embodied,

so that the shank will function to maintain the arch of the shoe permanently in the desired shape. f

The device is preferably made of sheet 'metal and is crimped or rolled to provide a longitudinal depending bead or fiange 6,

which is rolled j around an appropriately curved lpiece of resilient wire 7. The vertical width of the bead 6, including Vthe wire, is less than the thickness 'of the outer sole of the shoe. The -rear end of the wire l7 extends beyond the bead 6 and is flattened, 'v as shown at 7 n, partly to fill a depressed portion of the shank resulting from the formation of the bead 6. N earits front end, the shank may be provided withy depending tongues 8'for engagement in the shoe sole to cooperate with `the remaining structure to prevent displacement of the shank in any direction.

In the embodiment shown, the front end portion 4 of the shank is formed to provide a pair of'inclined tongues 9. These tongues extend downwardly and outwardly .and seat Y Y in the usual channels in the shoe sole, which channels provide portions 10 of the shoe sole resting upon the tongues 9 below the integral parts 11 of the shank.

As shown, the shank may be embodied in a shoe b forming a groove inthe sole 12 in which t e bead 6 is placed, the tongues 8 being forced into the sole, while the tongues 9 are pressed into the said usual channels. The parts 11 of the shank givey added strength to the sole' parts 10, so'that a freer interlocking engagement of the shank with v'the sole is obtained.

Preferably an elastic Cushion Y13 of rubber or .the like is placedV upon the rearor heel portion of the shank, the relationship thereof being indicated by dotted lines in Fig. 2. Upon this cushion a forwardly tapering part 14 is placed. The nails 15 are forced through the member 14V and the cushportion of the sole 12 and into the shoe heel.

-ion 13 and downwardly through the heelV A number of fastening tacks 16 are forced through the member 14- and the cushion 13 and into the heel portion of the sole in the primary assembly of the parts. The member 14 of the shoe terminates slightly in front of the forward end of the hole 2 and forms a shoe support for the shoe lining 17 which, in the embodiment shown, rests directly upon the shank.

In the modified form of the invention shown in Figs. 6 and 7, there is an appropriately shaped shank 18 having a depending bead 1.9 enclosing the resilient wire 2O having its rear end flattened, as shown at 20a, to fill a depressed part of the shank. r1`he rear end of the shank has a pair of side arms 21 of a length' to adord the necessary lateral strengthy in cooperating with the rearward extension 22 of the plate which compares with the extension 5 of the form of the invention lirst described. The 'front portion of the shank 18 may be provided with depending tongues 23 corresponding to the tongues 8. The extremity of the shank is cut and shaped to provide a pair of laterally and downwardly eXtended tongues 24 designed and adapted to be embedded in the sole channels in the manner of the tongues 9 and for the same purpose.

There may be other variations of the invention without departure from the nature and principle thereof. I do not restrict myself unessentially, but what I claim and desire to secure by Letters Patent is 1. A shoe comprising a sole having a longitudinal groove in the upper side of the shank portion thereof and having a longitudinal outwardly undercut ychannel at each side of the forward portion of said groove, a metallic plate having side portions of ape proximately uniform thickness resting upon the top of the sole at the sides of said groove, Y

a bead rigid with the underside of said plate tting closely in said groove, and a pair of outwardly and downwardly inclined tongues integral with the forward end of said plate extending downwardly and-laterally from ner the plane of said bead into said channe s.

2. A shoe comprising la sole having a longitudinal groove in the upper side of the shank portion thereof andhaving a longi tudinal outwardly undercut channel at each side of the forward portion of said groove, a metallic plate having side portions of ap proximately uniform thickness resting upon the top of the sole at the sides of said groove, a bead rigid witn the underside of said plate JULUS R.
