This invention relates to call: devices, and particularly to an improved means for associating a call: with a shoe sole.

Two types of calk devices involving removable cleats, now widely used with athletic shoes. include, respectively, an assembly in which a threaded stud or post is carried by and projects from the cleat to be screwed into a complementary holding member in or otherwise associated with the shoe sole, and an assembly in which the threaded stud or post is carried by and projects from the shoe sole to threadedly receive the cleat. The present invention relates particularly to assemblies of the latter type, which may be referred to as post type assemblies,

It is an object of the present invention to provide an assembly of the foregoing type which may be very eifectively and simply associated with a shoe sole and'in which the cleat may be removed without adversely loosening the cleatholding stud or post relative to the sole.

Another object of the invention is to provide a post type assembly involving a washer and holding nut on the outside of the shoe sole in which both the washer and the holding nut are eilectively held against adverse turning when the cleat is screwed oil of the post and away from the sole.

Another object of the invention is to provide a cleat assembly which is particularly rugged and in which the ground-engaging or cleat element proper may be worn appreciably without rendering the same unsafe and unsuitable for use.

A feature of the invention, therefore, resides in the provision of a cleat assembly including special interengaging means on the washer and holding nut elements for locking the same against relative rotation, and also a means on the washer element for gripping the sole against relative rotation.

Another feature of the invention resides in the provision of a cleat assembly including means whereby the extent by which the holding nut projects outwardly beyond the outside of the sole and the main cleat-seating surface of the washer may be reduced.

Another feature of the invention resides in the provision of a cleat assembly in which the washer element has an inner portion ofiset in the direction of the shoe sole, and with which a recess is formed in the sole for receiving this offset portion concurrently with the tightening of the holding nut relative to the sole.

Before describing the present improvements and mode oi'operation thereof in detail it should lie-understood that the invention is not limited to the details of construction and arrangement or parts shown in the accompanying drawing, which are merely illustrative of the present preferred embodiments, since the invention is capable of other embodiments, and the phraseology employed is for the purpose of description and not of limitation.

Referring more particularly to the drawing and first to Figs. 1 through 5 there is shown for the purpose of illustrating the present invention a portion of a shoe sole I I of conventional construc- 40 tion including an inner layer l2 and an outer layer l3, and in which there is formed a usual aperture It for receiving a cleat-holding stud l5. Advantageously this stud is formed with a threaded shank portion [8 adapted to project outwardly from the sole and with a head portion l'i adapted to engage the inner side of the sole and thuslimit axial movement of the stud in an outward direction. Projecting teeth l8 formed on the head and engageable in the sole as shown mm.

4, serve to maintain the stud against adverse turning movement relative to the latter.

Cooperable with the head portion II in maintaining the threaded stud IS in position relative to the sole is a holding nut l8. As is usual a Fig. 5 is a view of the side of the washer which washer 20 is interposed between the holding nut and the outer side of the sole.

f importance, however, the washer 20 and holding nut l3 are so designed and so associated with each other, with the stud l5 and with the shoe sole that when the cleat-holding assembly, including the stud, washerand holding nut, is finally and operatively associated with the sole as shown in Fig. 4, the holding nut is effectively locked against turning movement on the stud relative to the washer and the washer is effectively locked against turning movement relative to the sole and between the latter and the holding nut.

In achieving these results the washer is provided in the central portion 2| thereof with slots 22 and 23 which extend radially from and communicate with a usual stud-receiving aperture 24. Also, advantageously this central portion 2| is bulged or offset inwardly in the direction of the sole, and, as shown in Figs. 1 and 5, the washer is formed with the main body thereof, bent into a substantially spread U-shape to provide marginal portions 25 and 26 which when the washer is initially associated with the sole, as shown in Fig. 2, are spaced outwardly from the sole. This initial shape of the washer serves to likewise initially space from the sole, teeth 21 and 23 which are formed to project from these marginal portions.

Ribs 29 and 30 formed on the holding nut l9 and projecting therefrom in th direction of the washer are adapted to' fit in the slots 22 and 23 formed in the latter. Advantageously these ribs extend radially outwardly from the terminus of the threaded bore 3| in the holding nut and are formed with threaded inner ends 32 and 33 which form continuations of the wall defining the threaded bore of the holding nut.

In associating the cleat-holding assembly with the shoe sole, the stud I5 is inserted in the sole aperture l4 and the washer 20 and holding nut 9 located in position as shown in Fig. 2 with the ribs projecting into the slots.

Then. by means of a wrench or other suitable.

The relative position of the several elements of I the cleat-holding assembly to each other and to the sole after the holding nut has been tightened is shown in Fig. 3. Of importance, it is to be noted that a recess 34 has been formed in the sole to receive the offset portion 2| of the washer.

stud to complete the assembling operations of call: device on the sole. Alternatively, the flattening out of the portions 23 and 28 to engage the projections 21 and 23 in the sole may be effected concurrently with the screwing up of the cleat through the pressure of the latter on the washer.

As shown, the main body of the cleat may be of distortable material, such as rubber or the like, having molded therein an insert member 36 with a threaded bore 31 axially aligned with continuing bore 38 in the cleat body for receiving the stud l5. As is conventional the bore 38 terminates in a recess l9 formed in base 40 of the cleat for receiving the holding nut l9.

With the cleat and cleat-holding assembly in association with the sole as shown in Fig. 4, the base of the cleat is firmly seated on the seating surface 4| of the washer. Advantageously special means may be provided on the washer for gripping the base of the cleat and most effectively holding the latter against adverse unscrewing relative to the stud. As shown in Fig. 6, this gripping means may be provided by holes 42 formed in the seating surface of the washer and into which the rubber of the base may be forced when the cleat is screwed in place. Alternatively and preferably, this gripping means may be provided, as shown in Figs. 7 and 8, by projecting means such as teeth 43 punched out from the washer. If desired, and as shown in Fig. 9, teeth 44 may be formed on the base of the cleat for cooperating with the gripping teeth 43 on the washer. However, especially if the cleat be formed of distortable material, the gripping action provided by the edges defining the holes 42 in or by the projecting teeth 43 On the washer, alone will provide effective anti-rotation means even though the base of the cleat has no teeth formed thereon.

Frequently in actual use, the rubber of the base of a cleat will, in effect, become welded to the washer on the sole. Also, in use, the rubber defining the recess 39 is pressed against and sometimes becomes, in effect, welded to the holding nut. With a usual assembly, therefore, involving a usual and conventional holding nut and washer, when the cleat is unscrewed, as for the purpose of replacement the holding nut is often un- This recess is formed by the ribs 29 and 30, which portions 25 and 26 so that the projecting teeth 21 and 28 are embedded in the outer side of the sole as shown in Fig. 4. A ground-engaging cleat 35 is then screwed on the projecting shank of the screwed or at least partially unscrewed therewith. This permits an adverse backing off of the stud in the sole.

With a calk device constructed according to the present invention, the nut is effectively locked against unscrewing on the stud and the-washer likewise effectively maintained in place even though there be a drag on the nut and/or washer as the cleat is being unscrewed. Moreover, it is to be noted that if for any reason it be desired to remove the nut and/or washer from the stud, this may be easily done by bending the portions 25 and 26 of the washer to free the projections 21 and 28 from the sole and then applying a simple unscrewing action to the nut. Of importance, despite the most effective locking of the nut and washer relative to the sole and stud there is no adverse marring of the threads either in the nut or on the stud.

Also of importance, the locating of the holding nut in the offset portion 2| in the washer and the embedding of this portion in the sole, serves to diminish the extent by which the holding nut projects outwardly relative to the seating surface of the washer and at the same time insures a snug engagement of the washer with the sole. Thus it is possible to diminish the depth of the usual holding nut-receiving recess in the cleat base. This is advantageous in strengthening the cleat base; Also, by diminishing the depth of this recess the'stud -receiving insert 36 may be located in the cleat closer to the base thereof, thus providing more rubber between the insert and the ground-engaging end'of the cleat with attendant greater allowance forcleat wear before exposing the insert.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
