Y ATHLETIC SHOE.

Application led :December 29, 1928*. Serial 150,157,666!

This invention relates to improvements in shoes of the type in which friction devices are added to the soles for preventing slipping under stress.

The primary object in view is the simple, inexpensive, and efficient anchorage of cleats to shoe soles.

lfVith this and further objects in view, as will in part hereinafter become apparent and infpart be stated, the invention coniprises certain novel constructions, combina'- tions, and arrangements of parts, as subsequently specified and hereafter set forth in the appended claims. Y

in the accompanying drawing,

Fig. l is an inverted plan view of a shoe sole, embodying features of the present invention;

Fig. 2 is a top plan view of the same;

Fig. 3 is an edge view of the same;

Fig. 4 is an enlarged, detailed, vertical section through the sole, on a plane of the axes of one of the cleats, the cleat and its retaining screw being seen in elevation;

Fig. 5 is a sectional elevation of one ofthe cleats detached, the cleat being shown in full lines prior to its application and in dotted lines after application;

Fig. 6 is a section on the' plane indicated by line 6-6 of Fig. 2.

Referring to the drawing' by numerals, l indicates the sole of a shoe, to the tread and heel portions of which is secured a number of friction cleats, each consisting of an exL posed truncated cone 2, having a reduced shank 3 upstanding into the sole l. Sole 1 is formed with aperture 4, one for each of said cleats, each aperture being proportioned to snugly receive a shank 3. The formation of shank 3 leaves a circular shoulder 5 at the base of the cone 2, which shoulder outstands beyond the line of the aperture 4 and rests against the under face of sole 1. Said shoulder 5, therefore, receives most of the react-ive stresses incident to walking upon the cleats, and delivers same directly to the sole l, through which they are distributed substantially uniformly to the foot of the wearer. Each of said cleats, before anchorage in the sole, is formed with an aXial bore 6 which terminates a considerable distance short of the lower end of the cone 2. The cleat made up of the cone 2 and shank 3 is preferably formed of rubber of the somewhat hardened type commonly utilized for cleats of athletic shoes. The degree of vulcanization or hardening does not eX- tend to the point of rendering the cleat nolielastic. It does, however, extend 'sufiicie'ntly for rendering the cleat strong and wear re'- sisting. A screw 7 anchors each cleat 2 in rice.

place. Each screw 7 isfOrmed with a highl pitched or wide angled'tapering thread 8 Vof the type' commonly employed loniron screws used in wood, and known commonly aswoo'd screws. ordinary wood screw in three respects.l It is provided with a head 9 of relatively wide area Vand preferably circular in form, it isv truncated and has a fiat entering end, and it is case hardened. The head 9 is provided with openings 10-'-l0, adapted to receive the i shanks of a spanner wrench for facilitating rotation of the screw 1n threading 1t into* the bore 6 after the shank 3 has been seated snugly within aperture 4. The outer ter- Screw 7, however, dier's from an' minus ll of thevscrew y7,- as clearly seen in- Figures 6 and 7 is fiat, the screw 'being' truncated to present flat surface to the material at' the base of bore 6. Thread 8 remains the full width to the outer terminus of the screw; Bore 6, before anchorage of the` cleat, is' preferably cylindrical and of less diameter than the root diameter of the screw 7 at its smallest cross section.

In mounting the cleats, thev sole 1 is provided with the reqilisite number f aper# tures 4, and the shanks 3 are introduced therein until the several cleats are all set with the shoulders V5 restino against the under surface of the sole' l. crew 7 is then inserted from the' upper or inside of' the sole and screwed in shank 3 along and within bore 6 until the parts are firmly clamped i together. ln moving to this position' the screw and cleat assume the relative condition indicated in Figure 6. As the root diameter of the screw 7 is somewhat tapered adapted for players of golf or other outdoorV sportsmen particularly desirous of obtaining a good foothold when required, without going to the eXtreme of the use of the larger cleats commonly employed for toot ball shoes and the like.

However, the invention i-s in no sense limited to the particular use nor the exact size of the cleat employed. JAll cleats within the range of successful use ot whatever size are included within the scope and intent of the invention so long as utilizing'the features thereof. y l

`VVhat'is claimed is:

1. The combination, with a shoe sole having an aperture, of a cleat of readily eXpansible material having a shank adapted to snugly lit said aperture, the shank being formed with a longitudinal bore, and a screw of larger root diameter than said bore,

. threaded into the bore from the inner portion of the sole.

2. The combination, with ashoe sole havingan aperture, of an elastic hardened rubber cleat having a shank proportioned to snugly fit within the aperture of the sole, the

i cleat outside the sole being of larger diameter than the shank and formed with a shoulderoutstanding trom the shank and resting against the under surface of the sole, andV anchoring means extending from the inner portion of the sole and engaging said shank for causing said shank to spread into firm engagement with the inner surface of said aperture.

3. The combination, with a shoe sole having an aperture, of an elastic hardened rubber cleat having a shank proportioned to snugly lit within the aperture of the sole, the cleat outside the sole being of larger diameter than the shank, the shank being `formed with a longitudinal bore, and a screw threaded into said bore from the interior portion of the sole and spreading said bore and causing said shank to iirmly engage the sinner surface of said aperture.

4. The combination, with a shoe sole having an aperture, o1 an elastic hardened rubber cleat, having a shank proportioned to snugly tit within the aperture of the sole, the cleat outside the sole being of larger diameter than .the shank, the shank being termed with a longitudinal bore, and a screw having a larger root diameter than the diameter of said bore threaded into said bore from the interior portion of the sole.

5. The combination, with a shoe sole having an aperture, et a cleat of readily eXpansible material having a shank tted in said aperture, and a tapered, case hardened screw, having a truncated body and flat outer end and a wide angle thread, th 'eaded into said shank from the inner portion of the sole.

6. In combination with a slice sole provided with a hole, a vulcanized rubber cleat having a shank for receptioninto the hole in said shoe sole, a cylindrical bore within theshank, said shank having a shouldered portion protruded exteriorly throughsaid sole, said shouldered portion having the configuration of the trustum of a cone, the trun cated portion of which contacts directly with the ground, a truncated screw having a liattened head providing an integral disc for seating on the inner side of said sole when said screw is threaded into said cylindrical bore, the shoe sole being clamped tirmly between the flattened head ot' the screw and the exterior shouldered portion of the shank when said screw is threaded into said cylindrical bore.

7. ln combination with a shoe' sole provided with a hole, a cleat of readily eXpansible material having a shank portion adapted to fit snugly into said hole, said cleat` having an enlarged portion adapted to extend below the tread surface et said sole and provided with a shoulder portion adapted to engage the surface of the sole, a bore within said cleat shank, and a screw provided with a flattened head, said head being of greater area than said hole and disposed upon the upper side of said sole, said screw adaptedto be threaded into said bore.

n testimony whereof I have signed my name to this specification.
