INSTEP-PLATE FOR SHOES.
Specification of Letters Patent.
Patented Feb. 4, 1913.
Application filed August 7, 1812. Serial No. 713,934.
To all whom it ma? concern:
Be it known t-iiat I, CoLUunUs \VAurna GLENN, a citizen of the United States, rcsiding at Kent, in the county of Culberson and State of Texas, have invented certain new and useful Improvements in Instep- Plates for Shoes, of which the following is a specification.
This inventi0n-relates to a protecting plate to be secured beneath the instep or shank of a shoe, through which the wearer of the shoe may apply pressure to a spade or other implement, as in spading dirt, tamping ties, standing on ladders or any kind of work, where pressure is received by that portion of the shoe.
The object of the invention is to provide a protecting plate of this character which will satisfactorily serve the purposes for which it is intended and which will be of light, cheap and durable construction.
The invention accordingly consists in providing a plate of t in, but rigid metal, preferably steel, which is dished or convexed outwardly to resent an arched structure and which is provided with a surrounding flange perforated throughout; its extent, so that it can be intimately attached to the margin of the shank or instep of the shoe, as well as to the adjoining portion of the shoe tread to rigidly sustain the arched structure against spreadin and thus, notwithstanding the thin, ligfit character of the late, develop the desired rigidity and distribute the pressure received from the spade or other implement of reduced area over the entire area of.- the plate, so as to prevent discomfort to the wearer or impairment of the shoe. Preferably, the device is rovided with a rear wall perpendicular to tie plane of the plate and conforming to the front wall of the shoe heel for the combined purpose of protecting the heel and sustaining the plate against creeping on the shoe. The convexed surface of the plate is preferably serrated or roughened'to prevent slipping when applied to the implement.
The invention will be fully understood upon reference to the accompanying drawing, which-- v v p lgure 1 1s a PGISPGCtlVQVlGW showing the plate applied, and Figs. 2 and 3 are sections taken respectively on the lines 22 and 33 of Fig. 1.
1 represents the sole of the shoe; 2 the shank or instep and 3 the heel.
4 represents the improved wearim and protecting plate which is constructed with a marginal attaching flange 4 with numerous perforations to provide for intimately securing it throughout its extent to the shoe and with its area 4 within the attaching flange convexed outwardly and rovided wit-h serrations 4 and having at its rear end a vertical wall 4 conforming to and abutting against the front wall of the shoe heel, and the convexed portion of the plate prevents localizing on any part of the instep, the severe pressure of the reduced portion of the spade or other implement and distributes such pressure throughout the area of the plate. The arched construction also strengthens the plate against bending or indentation and thereby permits the use of very much lighter stock in stamping up the plate. The convex form insures the further advantage of localizing the pressure upon the serrated portion of the plate and preventing contact with the attaching nails which might otherwise soon be worn away or broken off.
I claim A protecting plate for shoescomprising a marginal attaching flange for intimate contact throughout its area with the shoe, a central area convcxed outwardly both transversely and longitudinally thereby spacing the central part of the plate from t 10 shoe and preventing pressure on the plate being localized on any part of the instep of the shoe to which it is attached, scrrations extending transversely of the convex area, and a vertical wall at one end of the plllate adapted to be secured to the heel of a s 0e.
The foregoing specification signed at Kent, Texas, this the 30th day of July, 1912.
