Application filed October 8, 1924. Serial No. 741,947.

. To all whom it may concern." 7

Be it known'that I, D vmH. GOLDMAN, a

citizen of the United States, residing at Cleveland, in'the county of Cuyahoga and 6 State of Ohio, have invented certain new and useful Improvements in Antislipping Devices for Shoe Soles and Heels, of which the following is a specification.

This invention. relates to improvements in anti-slipping devices" for shoe soles and heels having for an object to provide a novel form of ground or ice gripping surface such as will prevent slipping and serve as a cushioning means.

Another object is to provide a combined anti-slipping and cushioning means for footwear, this means including double action suctioncups and being adapted to function even where the sole has worn unevenly; A further object is to. provide a rubber .sole and heel integrally-formed and readily adaptable to a shoeor' the like, this sole and heel, including anti-slipping devices.

It is likewise an object. of :this invention 2 to provide co-acting gripping devices which will serve as air cushions to support a wearer of shoes or the like equipped with such devices.

Other objects will bein part obvious and in part pointed out hereinafter.

In order that the invention and its mode ofoperation may be, readily understood by persons skilled in the art, I have in the accompanying illustrative drawings, and in the following detailed description based thereon setout one possible embodiment of the same. v

Figure 1 is a bottom plan view showing the heel and sole integrally formed and including the anti-slipping devices;

Figure 2 is a longitudinal sectional View of the forward portion of a sole constructed in accordance with my invention;

Figure 3 is a sectional view showing the double suction cup which is associated with the sole portion,

Figure 4 is a sectional view showing the manner in which the suction cups are compressed to project the ice gripper for action;

Fi ure 5 is a detail sectional viewshowing t e relationof the double suction cups and ice gripping devices;

Figure. 6 is a plan view of an individual heel embodying the principle employed in the sole construction; 7

Figure 7 is a sectional view taken on the line 7-7 of Figure 6; V

Figure 8 is a sectional view taken on the line 88 of Figure 6.

Figure 9 is a detail plan view showing the relation of the double suction cups with the adjacent portions of the heel, and

Figure 10 is a detail elevation of one of the inner suction cups employed in the heel construction.

In this application I embody certain modifications which are designed to permit use of the principle employed upon rubber overshoes and ordinary rubber heels alike. The first form illustrated is that employed in rubber overshoe construction I and as shown, consists in providing an overshoe with a sole 11 of unusual thickness preferably approximately one-half inch and having a concave exterior or bottom face. The cavity 12 is substantially one-quarter inch in depth and is provided with a set of interconnected ribs 13 which may be arranged to effect any design desired. Theseribs 13 areprimarily adapted to form a plurality of individual air pockets or gripping cups 14'. which as shown, are so arranged that uneven wear upon the sole will not nullify functioning of the entire set of air ockets. It is apparent that these pockets unction individually. The ribs are substantially V-shaped in cross section, the truncated apex being disposed in a plane with the lower face of the peripheral wall 15 or sole itself.

(lo-acting with these cups or pockets 14 90 is a set of double suction cups or grippers 16, each of which comprises an outer hollow cylindrical body 17 formed of rubber and integrally molded with the sole portion. As shown, the opening or cavity 18 in the outer body 17 extends considerably below the plane of the bottom walls of the pockets, snugly and slidably receiving a compressible suction or gripping cup 19. The inner end portion of the compressible suction cup is corrugated, each corrugation 20 being hollow, as shown in Figure 5, whereby to provide an unusual degree of compression and consequently a suction which prevents slipping, as is obvious. While in this application I prefer cementing the inner end of the compressible cup to the inner wall of the opening 18 in the cylindrical body 17 it is to be understood that other means for fastening this" cup in place may be employed.

When a person is walking in shoes having soles constructed as herein outlined, the compressible suction cup 19 which projects slightly beyond the cylindrical body, first strikes the sidewalk or the like and is compressed thereby compressing a certain volume of air within the cup. The degree of compression of the walls of this cup is such as to cause the outer end of the cylindrical body 17 to strike the side-walk and spread laterally and grip the surface upon which the person is walking. It is clear that this cylindrical body will act with the inner or compressible cup 19 and tend to prevent lifting of the shoe from the sidewalk or the like.

It is obvious that air will be compressed between the corrugatedportions of the compressible cup and the adjacent portions of the cylindrical body, thereby providing an air cushion upon which the person wearing shoes equipped with such devices may walk.

Obviously there is a double gripping or suction such as will be unusually effective in preventing slippage. This form includes ice grippers 21 which are removable when they are not required. 7

In providing these grippers, I mold in the inner wall of the opening formed in each cylindrical bodv 17 an ice gripper base 22 comprising a washer 23 carrying an internally threaded neck 25 centrally disposed in said opening as shown in the detail Figure 5. Each ice gripper 21 is an elongated body 24 having an externally threaded inner end receivable in the internally threaded neck or socket 25. The outer end portion of the ice gripper 21 is hollow and has its edge beveled to form a sharp ice engaging tooth. This body has its intermediate portions provided with polygonal sides to permit engagement with a socket wrench or key whereby removal of the ice gripper may be effected when desired. As shown, these ice grippers terminate at the outer ends of the cylindrical bodies, thereby being normally enclosed by the compressible cups. As shown in Figure 5 the walls forming the double suction cups and the metal ice gripper may be subjected to considerable wear without interfering with the proper functioning thereof. In this figure it is also apparent that the inner suction cup normally projects a distance beyond the metal ice gripper thereby serving as a protector for said gripper.

However, upon compression of the cup 19 and body 17 as previously stated, the ice gripper will be projected for action. Due to the structure it is obvious that considerable wear may take place before functioning of the cups and associated parts will be affected. Each cylindrical body 17 is slightly spaced from the several ribs 13 formed upon the sole, the result being that the outer ends of said bodies may expand laterally as previously outlined.

The heels of the overshoes are provided with individual suction pockets and double suction or gripping devices upon the same principle" as that employed upon the sole portion.

I employ the same general arrangement in constructing a separate rubber heel for shoes, eliminating the metal grippers and the sockets heretofore referred to. Obviously the double suction cups or grippers 26 must be smaller than when used upon over shoes and consequently Ieliminate the formation of hollow corrugations in the inner compressible cups. The opening 27 through each inner cup 26 is plain, that is not corrugated, as shown in Figure 10, thereby retaining much of the suction effect herein before described. The provision of the set of individual pockets 28 upon the heel 29 in combination with the double suction cups as stated, creates an unusually effective antislipping device as well as forming a real air cushion. As illustrated, a set of nail holes is arranged between the ribs 30 of the heel to permit insertion of fasteners. The usual apertured washers (not shown) are molded in the heel for obvious reasons.

Obviously I may make certain changes in the minor details of construction and such of these changes as may fall within the scope of the appended claims, I consider within the spirit of my invention.

I claim:

1. In an anti-slipping device of the character described, the combination of a shoe sole of resilient material having a set of individual gripping pockets, a set of double relatively telescopic suction cups arranged upon the tread surface of the sole, and ice grippers associated with the suction cups and operable with compression of the cups.

2. In an anti-slipping device of the character described the combination with a shoe sole, of a pair of relatively telescopic suction cups, one of said cups being normally projected outwardly beyond the other cup.

3. In an anti-slipping device of the char acter described, the combination with a shoe sole, of relatively telescopic suction cups, one of said cups having a corrugated inner end portion.

4. In an anti-slipping device of they character described, the combination with a shoe sole, of a set of suction cups, pairs of said cups being relatively telescopic, one cup of each pair being corrugated to permit compression, and a metal ice gripper associated with each pair of cups and designed toproject for functioning upon compression of said cups.

5. A relatively telescopic pair of suction cups, the outer cup being slightly compressible, and the inner cup having its outer end extended beyond the outer end of the first named cup and having its inner end portion corrugated to increase its compressibility. r

6. A relatively telescopic pair of suction cups, the outer cup being slightly compressible, the inner cup having its outer end extended beyond the outer end of the first named cup, and having its inner end portion corrugated to increase its 'compressr bility, and a removable tooth-like ice gripper disposed within the inner cup and adapted to function upon compression of the cups.

7. A sole and heel integrally molded and formed of resilient material, and double telescopically arranged suction cups carried by said sole and heel.

In testimony whereof, I aflix my signature.
