(Ittomegs Patented July 18, 1933 UNITED. STATES IRVING S. GREENTREE, OF RICHMOND, VIRGINIA ANTTISLIP ATTACHMENT FOR SHOES Application filed April. 18,

This invention relates to anti-slip attachments for shoes, and more particularly to devices of this character which are especially though not exclusively adapted for use 011 golf courses and athletic iields in general.

It is well known that in playing various athletic games, such, for example, as golf, considerable difficulty is often encountered due to the constant danger of the players slipping and falling. This is due largely to therelative smoothness ofthe soles of ordi nary shoes worn by many players, and as a result it is often necessary to wear special shoes provided with anti-slip devices of va rious kinds, such as spikes.

An object of the present invention is to a provide an efiicient anti-slip pad which may readily be applied to and removed from the sole of an ordinary shoe.

A further object is to provide a detachable pad of soft, stretchable material such as rubher, which is provided with attaching means engageable with the sole only of a shoe whereby no straps or the like passing over the shoe top are required.

A. further object is to provide a resilient anti-slip pad having means for engaging and clamping a shoe sole and being formed to receive a hook or the like to facilitate stretching of the pad when applying the latter to a shoe or removing it therefrom. Other objects will become apparent from a reading of the following description, the appended claims, and the accompanying drawing, in

which Figure 1 is a perspective view of a shoe, and my improved anti-slip pad applied thereto;

Figure 2 is a top plan View of the anti- .slip attachment;

1932. Serial No. 605,972.

A preferred practical embodiment of the invention is illustrated in the accompanying drawing, in which'an anti-slip attachment generally designated A is shown in Figures 1 and 3 as being applied to the sole 1 of a shoe generally designated B.

The attachment A comprises a sheet or pad of soft resilient material 2 preferably of rubher or similar material formed with a plurality of spaced perforations 2a; and pair of sole-engaging and clamping elements 34 extending transversely of the pad and being secured to the upper face thereof adjacent the pads front and rear ends respectively by any suitable means such as rivets 5.

The attaching elements 3 and 4 preferably comprise metallic strips, the ends of which are bent upwardly and then inwardly to provide upwardly extending sole-engaging cleats 6, 7 8, and 9, the upper end portions of which project inwardly to overlie the shoe sole 1. The upwardly extending portions of the cleats preferably are inclined inwardly, this arrangement having been found to clamp the device to a shoe sole more efliciently.

Preferably the sides of the pad 2 are shaped so as to conform substantially to the sides of the shoe sole 1. The cleats 6, 7 8, and 9 are arranged in substantial parallelism with the respective adjacent portions of the sides of the pad 2 so that, when the pad is stretched longitudinally and then allowed to contract, the cleats, being inclined to conform to the slope of the shoe sole, will forcibly contact the latter due to the action of the pad in drawing all the cleats toward the widest part of the lateral swell in the sole 1. In

this way, the cleats serve to connect the pad to the sole in such a manner as to insure against accidental displacement yet permitting the pad to be disconnected by simply stretching it longitudinally to disengage the cleats at one end from the sole.

In accordance with one feature of my invention', I form the strip 4 at an intermediate point with an enlarged portion 10 and, with in the margin of the enlarged portion, I form an arcuate cut 11 to provide an car 12 which is bent downwardly into a substantially vertical position, a portion of the pad being cut away as at 13 to accommodate the ear 12. The ear is formed with a hole 14 adapted to receive a hook 15 shown in dotted lines in F igure 1. By means of the hook 15, the pad may be stretched to facilitate its being attached to or detached from the shoe sole without the users being obliged to grasp the pad itself, or the cleats, which not only would be awkward, possibly resulting in pinching of the users fingers, but also would be apt to soil the hands unduly.

In the modification shown in Figures 4 and 5, the strips 3 and 4t are formed with centrally disposed inwardly extending portions 16 and 17 respectively, each of which is held firmly against the top side of the pad by means of a rivet 18. The rivets employed in the modified construction are formed at the lower ends with conical heads 19 which extend below the bottom face of the pad and act as ground-engaging spurs, the rivets thus functioning dually to secure the strips 3 and 4 to the pad and also as anti-slip spurs. Obviously the pad, instead of being perforated, may

be corrugated or serrated so as to presenta rough ground-engaging surface.

I wish it understood that varlous changes in form, preparation, and minor details of construction may be resorted 'to within the scope of the appended claims, and I do not wish to limit myself to the specific design and construction here shown.

I claim:

1. A detachable anti-slip device for shoes comprising a stretchable rubber pad; unitary metallic strips extending transversely across the pad and being secured thereto at its front and rear ends respectively, each end of each of said strips being formed with upwardly extending sole-engaging cleats, the upper end portions of said cleats projecting inwardly; and means on one of said strips for receiving a hook forstretching said pad when applying said device to a shoe sole.

2. A detachable anti-slip device for shoes comprising a stretchable pad of soft material; unitary metallic strips extending transversely across said pad and being secured to the upper face thereof adjacent the front and rear ends of the pad respectively; an upwardly extending sole-engaging cleat at each end of each of said strips; and a downwardly extending parton one of said strips formed to receive a hook for stretching the pad when applying said device to a shoe sole.
