SAFETY DEVICE FOR FOOTWEAR Filed Oct. 31, 1955 Patented Apr. 30, 1935 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to safety devices for footwear and has for the primary object the provision of flexible elements lying partially within grooves or channels formed in the tread surfaces of footwear so as to provide anti-slipping mediums to permit the wearer to obtain firm traction when walking on any slippery surface or ground and which may be easily and quickly removed from the footwear when desired.

With these and other objects in view this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my inventicn, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary perspective view illustrating a boot or shoe with my invention applied thereto.

Figure 2 is a fragmentary plan view illustrating the grooves or channels formed in the tread surface of the footwear and receiving therein the anti-skid mediums,

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Referring in detail to the drawing, the numeral l indicates a boot or shoe to which my invention is applied and the tread surfaces 2 thereof have formed therein grooves or channels 3 arranged in spaced relation and transversely of said surfaces. Lying partially within the grooves or channels are flexible anti-skid elements 4 preferably in the form of chains carrying at their ends eye bolts 5. The eye bolts extend through openings 6 formed in the sole and heel of the shoe and which open outwardly through the side faces of said sole and heel. Nuts "4 are threaded to the eye bolts and are countersunk in the openings 5. By adjusting the nuts I on the eye bolts the anti-skid elements may be tensioned as desired and the nuts also permit the anti-skid elements to be removed from the shoe or boot when desired. The nuts countersunk as shown in the drawing prevent them from catching into obstructions during the walking of the wearer. The flexible elements 4 project beyond the tread surface of the sole and heel so as to bite into snow, ice, mud and the like to prevent slipping. The device also will prevent slipping when walking on hard slippery surfaces.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed.

Having described the invention, I claim:

1. In combination with a shoe having a sole and heel provided with relatively spaced grooves arranged transversely of the sole and heel, chain elements lying partially within said grooves, and means connected to said chain elements and to the sole and heel.

2. In combination with a shoe having asole and heel provided with spaced transversely arranged grooves and openings communicative with the grooves and extending through the side faces of the sole and heel, chain elements lying partially within the grooves, eye bolts connected to the ends of the chain elements and extending through the openings, and nuts threaded to the eye bolts.

3. In a shoe having a sole, a groove arranged a transversely of the sole, a chain element lying partially within said groove, and means connected to said chain element and to the sole.

4. In a shoe having a sole, a groove arranged transversely of the sole, openings communicative with the groove and extending through the side faces of the sole, chain elements lying partially within the groove, bolts connected to the ends of the chain elements and extending through said openings, and detachable fastening means on the free ends of said bolts.
