TRUSS FOR SHOES Filed Nov. 2. 1928 HLEXHA/DER ,E. 54 00K 41- roams):
Patented Dec. 17, 1929 UNITED STATES ALEXANDER E. BLOCK,'OF ST. LOUIS, MISSOURI TRUSS FOR SHOES Application filed November 2, 1928. Serial No. 316,641.
My invention relates to an improved truss for shoes, and has for its object to provide a front bearing-plate, an arched channeled body and a rearwardly-extending terminal butt.
In devising this new article of manufacture I have provided'means for keeping the sole, shank and heel of the shoe in alinement with each other and with the shoe-upper.
The rear terminal has all the advantages described in my United States Letters Patent numbered 1,602,793 issued October 12, 1926, wherein it is described and claimed as an integer; in the instant invention that rear terminal also forms an anchorage for the front terminal of the truss.
The front bearing-plate as illustrated has a channeled arched body extending to a rear butt adapted to be seated on the upper face of a heel and to substantially fill the space bound by the inner edges of the indrawn upper materials; the bearing-plate being arranged to be imbedded in the sole structure of a shoe, rearwardly of the line of the anterior 2 metatarsal arch of the wearer.
I have thus provided a true supporting truss for the human foot, extending from beneath the ball of the foot to a point beneath the heel; each of its terminal portions serving as an anchorage for the other.
Incidental to this construction is the rein-. forcement of the rear butt of my truss by downwardly-depending flanges at each of the marginal edges of the truss; the arched body being channeled throughout, and having downwardly depending flanges as well throughout its rear portion.
The truss of my invention is adapted to be substituted for what is known in the art as the ,cottage shank, but by its conformation eliminates the shearing stress exerted on the shoe sole by such cottage shank, and thus obviates the cutting and other danger to the sole which is incident to the employment of the cottage shank.
Drawings ing my invention.
Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal mid-section of the .same taken on the line 33 of Fig. 1.
Fig. 4 is a transverse sectional view taken on the line 44 of Fig. 1. i
Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 1.
Fig. 6 is a transverse sectional view taken on the line 66 of Fig. 1.
Fig. 7 is a transverse sectional view taken on the line 77 of Fig. 1.
Description.
The channeled arched-body portion A, at the line indicated as 55 in Fig. 1, has its rear upper edges 1313 (see Fig. 4) bent upon themselves to v form the depending flanges 1111, the depth of which flanges at various points throughouttheir length is outer edges of the slot 12. The slot 12 is provided to permit the insertion of a screw into the heel.
The butt B is perforated as indicated by 15 15 along its median line to permit the use of nails to secure the butt B to the heel;
The channeled body A is preferably contoured as shown on the drawings; having expanded shoulders 20-20 at or near the rear end 16 of its channel; this for the purpose of creating a broadened bearing surface and providing maximum strength at a line shortly in advance of the breast of the heel of the. shoe. The body A also has expanded shoul ders 1717, which are in transverse alinement forwardly of the shoulders 2020, lending added strength to the truss along the transverse line indicated as 55 in Fig. 1 of the drawings, and at the forward end of the rear portion of the channeled body A which has the depending flanges 11-11; the purpose of the shoulder 1717 being to impart additional strength to the truss at the point where the upper edges 1313 are deflected downwardly to form the depending flangeslL-ll (see Figs. 4 and 5).
The bearing plate 10, formed at the front end of the body A is flat, and intended to be imbedded between the layers of material formingthje sple o fjthe shoe; andis provided with't he perfbration 18 to permit the passage of a nail or screw securing the bearing-plate in place between said layers of material.
The front edge 19 of the bearing-plate. 10 is preferably provided with rounded" corners as shown in Fig. 1, to the end of preventing the cutting"ofthe sole niateiial by the plate lO during prolonged u seof the shoe.
