(01. sea-2.5) ’ 1 2 This invention relates to a cleat assembly for athletic shoes, and more particularly for football shoes. Cleats for‘ football shoes are customarily of frusto-conical‘ shape and are removably se cured to the‘ soles of the shoes. Cleats of this kind are‘ subjected to severe stresses when in use owing to the strenuous manner in which football games are customarily played. Hence it is im portion 26 of substantial diameter with a ?llet [9 . at the junction of the head andv shanik for strength. This portion of the shank is of‘ suf? cient length to extend through the innersole 2i) and the plate 22. If desired, it can also extend a part or all of the way through the outer sole [4. Beyond the unthreaded portion 25 is a threaded portion 28 of reduced diameter. This portion projects a substantial distance from the portant that the structure be strong at the points where stresses are severe. It is also important 10 outer sole I4 to receive the cleat l2 thereon. In order to secure the bolt ?rmly on'the shoe, that the cleats be ?rmly secured‘ in place, since a. plurality of prongs 30 extend from the head I8 cleats that work loose and come off are liable to through the innersole 20. These prongs are pref cause delays, to be a source of. annoyance to the erably longer than the thickness of the innersole wearer, and possibly to result in injury to other so that the ends of the prongs clinch against the players. steel plate 22 when the bolts are driven into place. It is an object of the present invention to pro On the projecting threaded shank portion 28 of vide an improved assembly for securing football the bolt is a nut 32 which is preferably in the form of a thin disc having a flat face bearing against placement, will stay in place while in service, and 20 the outer surface of the outer sole [4, when the nut is set up tightly on the threaded shank 28. are less liable to failure than the cleat assem~ If desired, the nut may be‘ provided with one or blies previously available. more marginal holes 34 through which tacks may For a more. complete understanding of the in be driven into the outer sole to retain the nut vention, reference may be had to the description against rotation but ordinarily such tacks will of an embodiment thereof which follows, and to not be necessary. The nut 32 is provided on its the drawing, of which: opposite face with a central reinforcing boss hav Figure 1 is a side elevation of afootball shoe cleats to shoes in such a manner that they can be easily secured to the shoes or removed for re ing a circular portion 35 anda superposed thicker polygonal portion 38 adapted to receive a wrench by which the nut can be rotated on the shank 28. A thin circular ?n 39 may also be formed on which a number of cleats are mounted; Figure2 is a bottom plan view of the ball por tion of the same; ' Figure 3 is a. fragmentary section on the line on the nut. 3—3 of Figure 2; Figure 4. is an exploded perspective view of several parts of a cleat assembly. Figure 5 is a sectional detail of. the nut of Fig“ ure 3. As shown in Figure l, a football shoe Ill is cus~ tomarily provided with a pluralityof cleats l2. which are usually of frusto-conical form, the bases being secured against the outer surface of the outer sole M of the. shoe. According to the present. invention,‘ bolts 16 are mounted on the shoe to receive and support the cleats, each bolt having a ?at head l8 which is preferably thin theface of the nut, the. knurling will lock with the. base. and prevent the cleat. from working so that it can readily be driven flush with the inner surface of the innersole 20. Between the . outer sole l4 and the innersole 29 is a rigid metal reinforcing plate 22, usually of steel. This plate, as indicated in Figure 2, is almost coextensive in area with the ball portion of the shoe and pro This ?n can be pressed or spun in against the shank of the bolt after the nut has been set up thereon as indicated in Figure 3. This helps to prevent the nut from working loose ‘on the bolt. The outer face of the nut 32 sur rounding the boss 36 is preferably knurled so that when a cleat I2 is screwed on to the shank 28 until its base of the cleat bears strongly against 50 vides greater rigidity and strength to this por= ' tion of the shoe sole with relatively little increase of weight. The plate 22 is provided with holes 24 through which the bolts [6 extend. Next to the head l8, the bolt 16 has an unthreaded shank 55 loose. As indicated in Figure 3, the cleat is made with a deep central recess 43 extending in from the base end of the cleat. An internally threaded member 42 is embedded in the cleat within this recess, the member 42 being adapted for threaded engagement with the shank 28 of the bolt. If desired, a spring washer 44 may be inter posed between the nut 32 and the cleat I2 as shown in Figure 4, this spring washer is prefer ably provided with a central aperture 45 which is polygonal in shape so as to ?t over the polyg onal portion 38 of the boss on the nut. This ef fectively prevents relative rotation between the 2,412,788 spring washer 44 and the nut 32. As shown in Figure 4 the washer is made with a series of pe ripheral ?ngers 48 but the washer may be made with a circular periphery if preferred. The washer is preferably knurled on its outer face so ‘ ‘ g ‘ I 4 through said innersole and clinched against said plate, said bolt having a threaded shank por tion projecting from the outer sole, a nut threaded on said shank, said nut having a thin disc portion bearing against the outer sole and that when the cleat is set up on the threaded a polygonal boss to receive a wrench, and a cleat shank 28 of the bolt, the base of the cleat will bear against the knurling on the washer and will having a nut embedded therein and in threaded thus be held against loosening.
