Jan. 29, 1935. EHRMANN 1,989,475

SHOE CLEAT Filed March 24, 1935 INVENTOR yam: 6%7774/7/7 ATTORNEY Patented Jan. 29, 1935 SHOE CLEAT Eugene Ehrmann, Milwaukee, Wis., assignor to Wisconsin Shoe Company, partnership consisting of Milwaukee, Wis., at Chester J. Krauthoefer and Emory W. Krauthoefer Application March 24,

- 3 Claims.

This invention relates to removable cleats for football shoes andthe like.

An object of the present invention is to provide a cleat having improved means for securely but releasably fixing the same to a shoe.

Another object is to provide a simple and effective but releasable anchorage for a. shoe cleat which will rigidly sustain the same against twisting or displacement and, at the same time, will not impair the pliability of the shoe sole.

Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

In the accompanying drawing:

Figure 1 is a face view of a shoe sole equipped with a set of removable cleats constructed in accordance with this invention.

Fig. 2 is a sectional view on a larger scale, taken along the line 2-2 of Fig. 1.

Fig. 3 is a sectional view, taken along the line 3-3 of Fig. 2.

Fig. 4 is a perspective view of the anchor bar shown in the other views.

The set of cleats 10, selected for illustration, are of the cone or tapered type, although the invention is equally applicable to cleats of the rib or rectangular type. They are shown mounted upon a shoe sole of well known construction having inner and outer sole leathers 11 and 12 with a thin sheet 12' of spring steel interposed therebetween.

The several cleats are removably attached to the sole through individual anchor bars 13, preferably of metal, permanently fixed to and extending transversely of the sole. In this instance eaoh bar 13 is secured to the sole by a plurality of nails 14, spaced longitudinally thereof with their heads 15 countersunk in appropriate depressions 16 formed in the outer face of the 40 bar. Each bar is thus effectively secured against displacement, .and due to the disposition of the nails along lines transversely of the sole, pliability of the sole is not impaired.

Each cleat 10 is provided with an open-ended slot 17 in the base thereof, adapted to snugly and slidably receive one of the anchor bars 13, the side walls 18 of each bar being inclined inwardly toward its base 19, or otherwise undercut, so as to interlock with the cleat. Each cleat is 1933, Serial No. 662,416

retained against tilting by its interlocking engagement with its anchor bar and also by the bearingcontact of its base 20 against the face of the sole.

Any appropriate means, such as a cross-key in 5 the form of a screw 21, may be employed to releasably lock each cleat to its anchor bar. In this instance the screw 21 is shown extending from one side of the cleat through a transverse hole 22 in the anchor bar 13 and screwed into 10 the body of the cleat beyond the bar. Upon withdrawal of the screw 21, the cleat may readily be removed by sliding the same lengthwise of thebar.

Various changes may be made in the embodil5 ment of the invention hereinabove described without departing from or sacrificing the advantages of the invention as defined in the appended claims.

I claim:

1. The combination with a shoe sole, of a set of cleats seated thereon, each of said cleats having a bottom face with an open ended slot formed therein, and a set of anchor'bars fixed to said sole and fitted in said slots, the sides of said bars 25 and slots being undercut and interlocked to therebyhold said cleats to said sole, said cleats being displaceable longitudinally of and from said bars, and releasable means for securing said cleats against displacement longitudinally of said bars. 30

2. The combination with a shoe sole, of a set of cleats seated thereon, each of said cleats having a bottom face with an open ended dove-tail slot formed therein, and a set of similarly shaped anchor bars fixed to said sole and interlocked 35 within said slots to thereby hold said cleats to said sole, said cleats being displaceable longitudinally of and from said bars, .and releasable means for securing said cleats against displace-v mentlongitudinally of said bars..

3. The combination of a shoe cleat having a bottom face with an open ended dove-tail slot formed therein, a similarly formed anchor bar interlocked with but longitudinally withdrawable from said slot, means for fixing said bar to 45 a shoe, and means for releasably locking said cleat against displacement longitudinally of said bar.
