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

and the plate 22. If desired, it can also extend
a part or all of the way through the outer sole

threaded portion 28 of reduced diameter. This
portion projects a substantial distance from the

where stresses are severe. It is also important 10 outer sole I4 to receive the cleat l2 thereon.

As shown in Figure l, a football shoe Ill is cus~

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

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

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
