RUBBER COMPANY LIMITED, 0F PETERSFIELD, ENGLAND I Boom AND snon Application filed November 23, 1929, Serial No. 409,357, and in Great- Britain May 27, 1928.

This invention refers to improvements in or relating to boots and shoes, and it has more particular reference to studs for the soles and heels of football. boots and the like.

Heretofore ithas been the common practice in connection with football boots and the like, to provide the soles and heels thereof with nailed-in leather studs, the nails passing through the several lifts of which the studs are usually formed and entering the leather sole. Some considerable difficulty, however, is experienced in obtained a proper fixing when the soles of such boots are formed of rubber or the like, and it is with the object of avoiding this disadvantage and of enabling the studs to be firmly secured thereto, that the present invention has been devised.

Now according to the present invention I provide a boot or shoe for football or other sports wear or the like in which the sole or tread portion thereof is formed of vulcanized rubber or the like having a plurality of metal inserts or ferrules provided in connection therewith and which are screwthreaded. for engagement with the screwedshanks provided on the studs.

In order that the present invention may be clearly understood and more readily carried into effect, it is hereinafter described with reference to the accompanying drawings, in which Figure 1 is a plan view of a football boot showing one of the studs removed;

Figure 2 is a side elevation thereof;

Figure Bis a detail sectional side elevation of a portion of the tread showing the ferrule embedded therein;

Figure 4 is a corresponding plan view thereof;

Figure 5 is a sectional perspective view of one of the studs;

Figure 6 is a plan view thereof; and

Figures 7, 8 and 9 are side elevations of different sizes of studs suitable for different conditions.

As .shown, I provide the studs 10 with a projecting portion or shankv 11 which is adapted to pass through and to-co-operate with a metal ferrule or plate 13 which may be embedded, during the recess of manufacture, in the sole and/or eel portion of the boot. The studs 10 may conveniently be formed of vulcanized rubber or the like and they may be provided with a projecting screw stem 11 the inner portion of which is suitably shaped, as at 12, and embedded in the material thereof so as to provide a firm fixing and prevent rotation. The projecting stem 11 is screw-threaded and is adapted to cooperate with an embedded ferrule 13 p'rovi'ded in the sole or heel portion 14 of the boot, the ferrule 13 also being suitably shaped or headed, as at 15, or perforated, so as to give it a firm fixing in the material 14 of the sole or heel. If desired, the plates may be made square, or of hexagonal or other shape, and they may be punched out with projections to prevent turning and to secure a good anchorage. The ferrule 13 is preferably moulded flush with or just below the outer surface of the sole 14 and is perforated, as at 17, and internally screw-threaded so as to provlde a screwed socket 18 with which the projecting screwed stem or shank 11 on the stud 12 is adapted to co-operate. The screwed plate and ferrule 13 is Preferably of slightly less thickness than the sole or heelplate 14 in which it is embedded, so as to leave a portion this end radial serrations or ribs 20, 21 may be formed or moulded on the said co-operating surfaces. In the case of a football boot, a pluralit of such screwed-in studs 10 would be 'provi ed, two conveniently being arranged, as shown, one on each side of the heel, and four at suitable distances apart on the sole.

The studs themselves 10 may be conic frustums or of cylindrical formation having plain outer surfaces, or they may be otherwise suitably shaped or roughened or provided with projections to increase the grip. In

the case oi? Alpine or other sports boots or shoes, the studs may be provided with projecting pinsoi metal or the lilre, or, alternatively, the whole of the stud may be termed oi metal.

The sole l may, as shown he backed by canvas 22 which may be prooted with rubher, or otherwise treated to secure adhesion to give rigidity to the sole and may be used in either single or multiple plies, It des red, the screwed inserts l3 may be placed between such ply to obtain better anchorage.

In a slightly modified construction it may be found desirable to malre the ferrules in the term of eyelets which are adapted be nserted and fixed in place in the soles alter they are vulcanized, the eyelets being screwthreaded as before, to engage the screwed shanks oil the removable studs and also hav ing radial or serrations on outside surface adapted to cooperate with the corresponding ribs or serrations formed on the bases of the studs.

By this invention it will he found to be possible to provide a lining arrangement whereby studs can be securely attached to the soles and heels of football and like boots. A further advantage accompanying the use oi the improved studs is that they can be removed. when-worn and replaced by new ones, without in any way damaging or impairing the strength and durability of the sole. Further, in the case of football boots the studs could be made of ditierent sizes, as indicated in Figures 7, 8 and ll, those shown in Figure 7 being suitable for Association football in dry weather; thosein Figure 8 for Association football in wet weather; and those shown in Figure 9 being best suited for Rugby football. In some cases sets of studs of different sizes may be provided for use in connection with a single pair of boots,- the sets being exchanged to suit the play or weather or the purpose for which the boots are to be used. Where more permanent fixing of the studs is desired, cement or rubber solution may be used when securing these in place. The interengaging metal portions may be made of rustless or other steel or metal, as may be found to be most suitable in practice or desirable from a commercial or economical point of view.

In some cases, in order to afford further support to the studs and in order to prevent their being kicked or broken oil, a buttressed ridge may beprovided on the surface of the sole in order to provide a depression into which the base of the stud is adapted to nest. Alternatively, the depression or circular cavity may, if desired, be formed in the thickness of the sole itself. Both these arrangements also serve to provide a more watertightjunction between the stud and the sole.

What I claim is in sport footwear. a ferrule embedded in isomer the sole and having an upper flange to be embedded in and interlocked with the material of the sole coincident with the upper surface thereof, said ferrule including a hollow threaded section extending toward and terprojections adapted to interlock with the proj ect-ions of the sole, and a shank embedded in the stud and extended above the upper surface thereof as a threaded projection to cooperate with the threaded portion of the ferrule, the projecting length of the shank beyond the stud beingless than the threaded portion of the ferrule whereby the shank may be united t-o the ferrule to compel a pressure interfit. of the locking projections on the sole and on the stud.

In witness whereof 1 have hereunto signed my name.

FREDERICK WlLLlAM EAST.
