The present invention relates to cleats for football and similar sports footwear and to the method of making the same.

It is a well known fact that previously various types of stud cleats have been marketed, to some extent varying as to shape and materials used. By way of example it may be mentioned that hard rubber has been used, but experience up to now has proved that the only stud widely adhered to by the overwhelming majority of players is the i one made of leather and secured to the sole by means of a nail.

However, studs made of leather have several disadvantages. They are rather easily worn out and must therefore be exchanged frequently, and being secured to the sole by nails which are bent on the inside, they will have to be forced loose by means of tongs, whereby the sole will be torn. Little by little, the sole will make a very insecure base for the new studs, and it may even be completely useless. The comparatively large number of holes through the sole will impair the stiffness of the sole in such manner that the studs cause a pressure on the feet of the players. Furthermore, the holes contribute to absorption of moisture from the ground, whereby the sole will become soft and weakened. This will make the insole uneven and bossed because of the pressure from the studs.

The present invention has for its object to reduce these disadvantages by inserting into the sole a metal plate to which the studs are secured by means of screws. This means of attachment has been used as far as studs made of hard rubber are concerned, but has not been applicable to studs made of leather. It is a fact that the leather stud together with the screw must form one compact piece, and this has hitherto not been obtainable by simply screwing loose disc-shaped leather pieces to the sole. According to the present invention this problem has been solved by securing the leather disc to the screw by subjecting the discs to an axially actuated pressure causing a permanent reduction of the thickness of same. i

The procedure according to the invention is, by way of example, illustrated on the accompanying drawing forming a part hereof and wherein:

Fig. 1 is a top plan view of an assembly provided during an initial step of a method of producing cleats according to one embodiment of the present invention;

Fig. 2 is a side elevational view, partly broken away and in section, of the assembly of Fig. 1;

Fig. 3 is a top plan view of a completed shoe cleat formed from the assembly of Figs. 1 and 2;

Fig. 4 is a side elevational view of the cleat of Fig. 3;

Fig. 5 is a top plan view of an assembly provided during an initial step of a method of producing cleats according to another embodiment of the present invention;

Fig. 6 is a side elevational view of the assembly of Fig. 5;

(Cl. 12142) s Fig. '7 is a top plan View of a completed shoe cleat formed from the assembly of Figs. 5 and 6; and

Fig. 8 is a side elevational view of the completed cleat of Fig. '7.

Figs. 1 and 2 illustrate the first stage in the procedure 5, in which several leather discs, which prior to this have been provided with a centrally located hole 2 have been threaded on to the screw 3. Upon this the leather discs and the screw are placed in a press, whereby they will take a shape as shown in Figs. 3 and 4, where the thickness has been considerably reduced. The example shown indicates how a conical stud is made. In this case, leather discs of different diameter are used, and by pressing them in a mould having a conical inner wall, the finished stud will get an even surface.

During the pressing operation the leather discs are pressed so forcibly against the screw that the constituent parts form one compact piece. When the stud is to be screwed into the sole it will be possible to turn the stud without using a screw-driver. As will be understood, the stud may be screwed in position by means of tongs.

In Figures 5 to 8, inclusive, is shown a stud, which is made in a similar way, but in which case there is fashioned on the end of the stud a covering plate 4 which is secured by means of tacks 5 to the other discs. As a matter of course, the outer disc will be worn out first, and this may be replaced by a new covering plate without necessitating the removal of the stud itself.

In case cylindrically shaped studs are to be made, the procedure is the same, with the exception that, in that case, the discs to be used have the same diameter and that the pressing operation takes place in a mould having a cylindrical inner wall.

I claim:

A process of making studs for football and other types of sports footwear consisting of forming a central hole in each of a plurality of leather discs, passing a screw through the registering holes in said discs and subjecting said discs while threaded on the screw to axial pressure to compress and consolidate the same.
