In the drawings I h'a've [shown three forms of the inveiitiohlbiit in allot them flexible arms ex- ..tei d inwar'dlyi'rom the tapered corners to 'lie in 1adia1 recesses or channels formed in the bottom of .the circular s'otiomithe arms being provided with lateral proiec'tiohs :or lugs to enter a I socket or sockets formed in the section. These arms' and their projections or shouldered (portions will be retained to some extentlin the section by :friction andbythe resilience of the material but; preferably employ other fastening means which'may'or that not also .assist in holding th section in its =adju'stedpos'ition'in the recess of the body portion of the ir'ub'berhe'el. .By the useof rubber herein it is to berunoler'stood that the material used may h'enatiirairiihber, synthetic-rubber,resilient plastic or othei rubber-like resilientfmaterial. V

Referringamore particularly to Figs.v 1-6, the letter S clenotesia portion-of a shoe, hootor the like andl-i the usuaileather heel to which the rubber heelisnailedor otherwise fastened. The-i111 proved rubber .heel comprises abody 15 molded from resilient rubber-like material with a substantiallyyei-rcular recess min the rear 'portionrof its bottom for the r-recepti-on of an adjustable :fcircular wear section H. The formation of the recess I6 leaves two rearwardly tapered wings or corners I8 disposed along the opposite side edges of the section H. The body I is moulded with the usual dished or concave top face (not shown) so that its edges will be in tight contact with the leather heel when nailed thereto. Usually five nails I9 are used and they are driven in holes 2E! until their heads engage the usual Washers 2i molded in the body. Provision is made whereby some of these nails are driven entirely through the rotatable section in any of its adjusted positions so that the assembled sectional heel may be fastened as a unit to the shoe.

Extending inwardly from the end portions of the tapered corners I8 are flexible anchoring members or arms 22 which are provided with laterally projecting lugs 23 preferably disposed at their free ends. These arms which may be straight or tapered, are alined transversely of the heel and are received in radially disposed recesses or channels formed in the bottom of the section I! so that they will lie flush with the bottom of the heel. As shown in Fig. 2 these channels are formed by the end portions of a single diametrically extending channel 24, and hence this section Il may be turned to either of two adjusted positions but in the other forms two diametrically extending channels at right angles to each other are provided so that the section may be adjusted to any of four positions. The arms 22 may be molded in one piece with the body I5 in which case they will also be resilient or they may be attached to the corners It in any suitable manner. As shown the arms are flat but at their outer ends they are formed with thickenedportions or lugs 25 which extend inwardly from the tapered corners I8 to provide a substantial connection between these parts. These lugs or thickened portions 25 fit in similar shaped notches 26 formed in the peripheral edge of the circular section H to assist in holding thelatter in an adjusted position. The notches 26 are at the ends of the channel or channels 24. Due to the resilience of the material, the arms and their outer lugs 25 may be sprung into and out of the channels and notches. The arms 22 maybe of various lengths, and as shown in Fig. 2, they do not extend to the center of the section I1. In this form the lateral projections or lugs 23 are of cylindrical shape and are adapted to be sprung or snapped into circular holes 21 formed in the bottom of the diametrical channel 24. The shouldered engagement between the projections 23 and holes 21 will prevent endwise movement of the arms and hence hold the tapered corners I8 in proper engagement with the section I I.

Various additional means may be provided to hold the arms in overlapping engagement with the shiftable section I I. Imay form the arms with nail holes with sockets to receive washers. As shownin Fig. 5 holes 28 may pass through the centers of the projections 23 and receive nails 29, the heads of which engage the washers 30 in the bottoms of sockets. These small nails may be driven into the body I5, and even further, into the leather heel but they are easily pried out when the section I! is worn at one point and is to be shifted to another position. These parts also serve to hold the section I! in its recess I6 but other means may be provided to accomplish that result. For example in molding the body I5, the bottom of the recess I6 may be made rough as indicated at 3| in Fig. 3 and a similar roughened annular band 32 may be molded on the upper face of the section I! as shown in Fig. 6; and then when certain of the holes 39, 4i).

these parts are assembled a light coating of rubber cement may be applied to these contacting roughened areas. Or I may use at least one screw or bolt to fasten the section I'I. As shown in Fig. 4, the section may have a central hole 33 to receive a bolt 34 which passes through a hole at the center of the recess 13 and engages a nut 35 molded in the body or set in a similar shaped socket molded in the top of the heel body. Or an annular series of holes 36 may be formed in the section II, one of which may receive a suitable fastening. The number and arrangement of the holes 36 is such that in either of the two positions of the section I'I, three of these holes will register with the three rearmost holes 20 so that the nails I9 may be driven through them and into the leather heel, as will be apparent upon reference to Fig. 4.

The embodiment shown in Figs. 7, 8 and 9 is quite similar to the first form and the same numerals with exponents will be used to designate the corresponding parts. The principal difference is that the arms 22 are made longer so as to abut each other at the center of the heel and the projections 23 are of rectangular shape so that both may be snapped into a square hole 2'! at the center of the section I I and fill the same. Further, two of the diametrical channels 2d at right angles to each other are provided so that the section may be adjusted to four positions. The nail holes 28 are formed in the intermediate portions of the arms instead of near their ends, and the arm fastening nails 29* engage washers 3t embedded in those portions of the arms as seen in Fig. 9. These nails 29 also pass through holes 39 in the section I'I and holes 43 in the body, there being four of each of the holes 39 and 50 so spaced that in any adjusted position of the section the holes 28 will register with The nails 29 may therefore be driven into the leather heel after the rubber heel has been fastened thereto but these nails may be readily pried out when the section I! is to be set in a new position. The five holes 20 for the heel fastening nails I9 are arranged differently in this form. The three rearmost holes 20 are disposed so that they will be opposite the crossed grooves 24 in the different positions of the section Il and hence the latter is formed with only four equally spaced holes 36 The arms 22 have holes 4I so positioned that they will register'with two of the holes 36% in any adjusted position of the section Il The registering of three. of the holes 3t with the three rearmost holes 2i permits the nails I9 to be driven into the leather heel while the rubber heel is an assembled unit. While the bottom area of the body I5 in rear of the recess I6 may, in this form, he made plain as in the first form, I have shown shallow grooves 42 which produce anti-slipping cleats 43 at the bottom of the for ward portion of the heel as seen in Fig. 7. .I have also shown in Figs. 7, 8 and 10 a removable metal wear plate 44 which may be used if desired and which is disposed at the center of the rear of the heel. This heel plate is of right an,-

gular shape having a short upright arm 45 to fill the notch 26*, which is at the center of the rear of the heel, and a long arm 46 which enters the adjoining channel 24 as seen in Fig. 8. The arm or branch 46 has a hole 4! which will register with the alined holes 39 and that are rearmost to receive a fastener 48 such as a Wood screw but which may be a bolt and nut similar to 34, 35. The plate 44 may have an additional hole 44 to sweats? register wlth. the rearmost hole .38 so that the rear nail .laamaybe drivenwhen the-plate '4 4.-i's on-the assembled rubber. heel. When the section li is. to be...adjusted,.the wear plate .is of course removed but it may be replaced in the notch and channel that are rearmost in the'new position of the section. In. all other respects this second form is the same in construction and operation as-tnefirstrorm. i

third form shown in Figs. 11', 12 and 13 is quite similar to the second form since the rotary section H has two intersecting ahdrdia metrically extending channels 24* which also open into a single cent-m1 hole 21 formed in the seetiOn; t I'eC'ei'VebOth Of the 1atera1 projections 23 oh the flexible arms 22?. However in this form the socket means, corresponding to the two holes ZTinthe first form and the square or rectangular hole 21 in the second form, is a circularholeffl and the lugs or projections 23 whichcorrespond to the previously described parts 23 and '2'3 ,;are fiat and enlarged circular heads dispose'dinsuperimposed relation inthesock'et ihear'is u es seen in Figs. 12 and 13. {The flexibility of the arms 22 permit first one head or projectionll3 to be snapped into the bottom oi tl e hole 21* and then the other to be sna'pped in, on top of :the first. Th ili'fei'r'r ost head"23 -f has its edge slightly cutaway at '50 in Fig. 11"; and as'shownat '5! injFig. 13, ,it h as a,beveled portion to engage a corre sponding beveled "portion at the juncture of the lower or inner headwithits arm 22*. In this form the arms zz a're'not fastened by nails. Instead, a single fastener 52 corresponding somewhat to the bolt 34, is used to not only fasten the and a central hole in the center of the recess lG and into the leather heel as clearly shown in Figs. 12 and 13. In this form the section l'l is also formed with four equally spaced holes which register with the three rearmost holes 20* for the nails 19 which fasten the rubber heel to the leather heel. To permit these nails to be driven with the parts assembled, the arms i2 are also formed with holes 4 I b which register with certain of the holes 36*, as seen in Fig. 13. In Figs. 12 and 14 I have shown a metal heel plate 44 similar to the one shown in Fig. 10, which may be used with this third form. In Fig. 11 it is only shown in dotted lines. It consists of a thin sector-shaped plate with a thickened right angular part having an upright leg 45* to fill the rearmost notch 26 and a longitudinal leg 46 to lie in the adjacent channel 24 The plate may also have a thickened portion 53 shaped to overlie one of the arms 22 which is made a little thinner as shown at 54 in Fig. 18. When this heel plate is used the rearmost nail la is replaced by a wood screw 48 as shown in Fig. 12. The screw is inserted in a hole 41* which registers with the rearmost holes 36 and 20 and it is threaded into the leather heel. The plate is also shown with another hole 55 which registers with the hole M in one of the arms 22 so that a screw similar to 48 may be used to more securely fasten the heel plate.

It will be noted that in all three forms, the rotary section has channel means to receive the flexible arms and also socket means to receive the lateral projections on the arms, the socket means and the projections forming coacting shoulders which prevent the arms from moving outwardly and hence the tapered corners to which the arms 6 are united will be prevented from spreading away from the periphery of the section. When the arms are of resilient material the projections may be made to snap into the socket means, but whether resilient or not, all forms shown herein have some 'i neans for retaining the arms in the section when the heel applied to a shoe.

While I have shown the rubber heel applied to a leather heel, it will be understood that the rubber'he'el may be made thicker and applied directly to the rear portion of the shoe sole.

From the foregoing, taken in connection with the accompanying drawing, it will be seen that novel "and advantageous provision ha been made for'ca r rying out theo-bje'cts of the invention, and While'preferences have been disclosed, attention invited to the 'po'ssibilityiof making variations thescope of the invention asclaiihed.
