SHOE ANTI-SKID DEVICE Filed Nov. 8, 1946 VINVENTOR. Way/7e 6/77/27;

iatented Mar. 23, 1948 UNITED STATES PATENT OFFICE 2,438,193 y SHOE ANTISKID DEVICE Wayne Smith, Decatur, Ga. Application November 8, 1946, Serial No. 708,609

This invention relates to new and improved anti-skid means for application to shoes, boots and the like.

The primary object of this invention resides in the provision of means adapted to be quickly and easily secured on a boot, shoe or the like to prevent the slipping and sliding thereof when engaged in such activities as golf, baseball, mountain climbing and other such activities requiring a sure footing at all times.

Another object of this invention resides in the provision of an anti-skid device of the character described which is simple in its operation of detachable clamping means on a boot or shoe.

Still another object of this invention is the provision of an anti-skid device of the character described which is of extremely, simple, durable, and inexpensive design.

Still further improvements and advantages of this invention will readily appear'to those skilled in the art when the following description is read in the light of the accompanying drawings in which:

Fig. 1 is a top plan view of the anti-skid device.

.Fig. 2 is a bottom view of the device affixed to a shoe.

Fig. 3 is a vertical section of the device taken on line 3-3.

Fig. 4 is a side elevation a shoe.

Referring now to the accompanying drawings, a flat, substantially rectangular metallic plate A has a curved end I on one short side thereof and two perpendicular flanged ears 2 and 3 extending upwardly from its two opposite long sides adjacent the curved end of the plate. The two ends of a conventional divided buckle strap 4 are secured by rivets 5, or the like, to the two ears 2 and 3 respectively to form an adjustable loop over the top of the metal plate A.

A plurality of metal spikes 6 are secured to plate A by conventional flanged heads 1 and 8, positioned on opposite sides of said plate with the sharpened ends of the spikes depending downward from the underside of the plate. These spikes, 6, are disposed and secured in definite design upon the area of the underside of the plate A so as to form a good surface engaging means on the plate.

Situated substantially in the center of the upper face of the plate A is a hard rubber triangular pad B. which is secured with one apex thereof disposed forward toward the curved end I of the plate A.

A conventional butt hinge 8 is secured to the of the device affixed to 2 Claims. (01. 36-717) upper face, atthe back end of the plate A with its axis I0 beyond and extending substantially parallel with the back end of said plate A, the extended half 'II [of said hinge being pivotally mounted for movement about said axis.

A pair of elongated braces I2 and I3, of

identically opposite construction, are secured by respective rivets I4, in spaced relationship, to the extended half I I of the hinge 9, perpendicular to the hinge axis. These braces I2 and I3 are provided with perpendicular upwardly disposed flanged ears I5, on their outside edges, which are adapted by hooked ends I6 thereon to securely clamp the extended portion ll of a shoe sole I 8.

These braces I2 and I3, are also provided with perpendicular depending flanged ears I9 on their inner adjacent edges. These ears I 9 are provided with apertures which loosely receive a. threaded bolt 20 therethrough by means of which the extended ends of the braces are adjusted to varied width shoes. Bolt 20 may have continuous threads and a nut screw threaded thereon to compress the lever ears I9, or if desired, may be provided as a conventional skate clamp screw having oppositely threaded end portions engaged in oppositely screw threaded apertures, the ears I9, in such case, preferably being pivotally secured to the respective braces.

By placing the forward portion of the shoe sole on the upper surface of the rubber pad B, which forms a non-slide engagement with the sole, the strap 4 may be looped upwardly and tightly over the top portion of the shoe thus securing the plate A in a tight adjacent postion thereagainst. The braces are then pivoted on their hinge axis upwardly so that the hooked ends I6 of the ears I5 may be caused to engage the extended portion I! of the sole I8. By turning the bolt 20 the hooked ends I6 are drawn together clamping the braces upon the arch portion of the shoe sole I8.

Thus it may be seen that a durable, simple and inexpensive non-skid device has been provided which may be quickly and easily attached to and removed from a shoe, boot or the like.

Having thus described and explained the construction and use of this device, what I desire to claim and secure by Letters Patent is:

1. A non-skid shoe attachment of the character described comprising, a flat metallic plate of substantially rectangular shape, a plurality of surface engaging spikes secured to and depending from said plate in a set pattern, a pair of oppositely disposed vertical ears upwardly flanged from forward sides of said plate. an adjustable strap secured to and interconnecting said ears in a manner adapting it to encircle the shoe upper and maintain said plate adjacent the underside of the sole of said shoe, a pair of oppositely identical braces disposed at the rearward end of said plate, hinge means and pivot means attaching said braces'to said plate for movement about a common axis substantially parallel to the rearward edge of said plate and about individual axes substantially perpendicular to said common axis, means carried ibyltheoutside edges bfrsaid braces adapted to securely engage theeitthded-pOrtion of the sole of said shoe, and screw means operatively connecting said braces to clamp said shoe sole between said sole-engaging means.

2. A non-skid shOe attachment of the character described comprising, a flat metallic plate erasabstantially rectangular shapeadapted-topartially conform with a forward sole 'portion'of a slide, a plurality of surface and depending from saidgplate in a predetermined and desired pattern, atriangular hardrnhberpad 'secured to the upper'face-pjf said-plate substan: tially in the center thereof adapted for .non slip engagementwiththe sole of said sh apair of engaging spikes securedfltd" tially the arch means interconnecting said adaptedattheir'ends to -securely engage the ex-;
