, isaside'elevationof thestud before 100 The advantages of the inventionas here outlined are best realized, when all of its features and instrumentalities are combined in one and the same structure, but, useful devicesmaybe produced embodyingless than the whole. q

It will be obvious to those skilled inthe art to which the invention appertains, that the same may beincorporated in several different constructions. The accompanying drawing therefore,'is submitted merely as showingthe preferred exemplification of the invention.

According'to this invention the tip is mounted in permanent engagement with the base of the heeL permitting the employment of improved simplified-fastening means which are nevertheless absolutely rugged and reliablein use. In this. way all possibility of accidentalor unintended detachment ofthe tip from. the base 'of the 7 heel which may occur,.where "the fastening means permits detachment of the tip 1110116 way ;or another, is-ehminated. By

- this invention the stud of the tip is of hollow form and is headed over the anchor plate in the base. A washer is provided between the anchor plate and the head of the stud so that the rotation of the tip may not be frictionally impeded. This washer, furthermore. preferably has an opening of slightly, smaller diameter than the opening in the anchorfplate so that on heading over the studthelatter will not be caused to grip or engage the anchor plate. The tip has an integral shoulder concentric with the-stud and extending into an opening in the base so as to have vertical abutment relation with the base anchor memher. This prevents vertical movement of the stud with respect to the anchor member referred to and accordingly any squeaking that might resultfrom said movement where the metal parts have rusted is prevented. A second washer may be. positioned between the shoulder and the anchor member ofthe base so as to; prevent any rubber from forcing-its way toth'e bearingof the stud. To prevent unintendedrelative movement as between the tip and the base the former is provided with a plurality of concentric pits and the latter with one or more projections to selectively engage in said pits. This feature of the invention,however may also be embodied in aconcentric series of notches or ridges formed in the tip to engage selectively with a-plurality of similar notches or ridges on the base at the rear portion thereof. To facilitate attachment of the heel to a shoe the base and tip are provided with registering holes so that fasteners can be passed through the holes in the tip and thence into the base to secure the latter to a. shoe. In order to permit the heelto be used with shoes of--various forms,

the base is provided with a projecting portion between the planes of the seat and upper surface thereof which projecting portion is buffed down to suit the size and form of the shoe! This projecting portion likewise pre: vents'the tip from being bufiedjand consequentlyTfrmn losing its true circular quality. Likewise: it safeguardsthe short side flanges ofgthe base from being damaged during the buffing operation. It has notches that act as a. guide and facilitate accurate positioning of the heel on the shoe before nailing; the said 1 notches also indicating the maximum depth of buiiing.

. Referringv in detail to the drawing 15 de notesa device embodying the invention. The same is seen to comprisea heel attached to a shoe 16 and prior to the b-ufiing operation. The heel Q15. includesla base 17 which may be made of any suitable material well known in the art but preferably of rubber. The said base ha san upper surface 18 that is normally glued to the leather heel portion 19 of the shoe and a tread portion 20, rat its front end the base is formed witha breast portion 21 and it includes a'circular se that extends from the breast portion to the rear end of the base. Accordingly the breast portion comprises an inner arcuate wall 23 and terminates in the rearward extending side flanges 24.

vMolded in-the base is an anchor plate 25, the same being preferably positioned between the surface 18 of the base and tl efseat 22 thereof. Said plate is ofcircular form and is preferably concentric with the seat referred to. In

the center of the plate is an opening 26 to receive the stud as hereinafterdescribed. A

plurality of relatively large openings 27- are formed in the plate through which rubber may flow so as to strongly secure the anchor plate in the heel base. periphery of the anchor plate are a plurality of nail or fastener holes surrounding which are thecup depressions 29 which in the finished heel extend substantially to the surface 18 of the base and provide substantially sharp in proximity to the ed es tobite intofthe' ermanent heel seat of jecting porti0n50 the sides 5% of the-heel base may be straight and parallelv and the breast:

portion 17 may be slightly larger than usual so as to permit the heel to'be buffed down at' the sidesbi and at the front face 55. of the breast to conform to the shoe as shown in dot and dash lines 56 and 57.

In Figs, 10 to 13 is shown a modification embodying the invention." This heel is, in all particulars the same as that herelnbefore described with the exception of the, means- 1 tion of the tip. The length of the ridgesis considerable so as to provide ample bearing relation. The'length of the ridges 60, however, is greater than that of 63 so as to provide end spaces 64 for the reception of any dirt or the like that may theridges in theflbase are slightly are shaped lengthwise so as to have a tendency to press any dirt that may accumulate in the recesses in the tip to the end spaces 64. By this construction if the operator should desire to turn the tip in order to present a new wearing surface at the rear of the heel, it is merely necessary for him to lie): the tip 61 at the rear of the heel away from the base 62 and then to rotate the tip to any desired extent. Thereafter the tip is released and will spring back into normal engagement with the base. A multiplicity of the ridges and their comparatively small size'insures of proper coaction withoutthe necessity of exerting any particular effort to bring the ridges into In. ting coaction. Particularly is this the case where the operator has exerted pressure on the heel in the normal courseof wearing the shoe. The respective ridges can be inexpensively molded in the rubber and constitute a simple effective and highly convenient means for retaining the tip against unintended rotation with respect to the base of the heel.

It is thus seen that we have proviced a device that fulfills the several objects of the invention and is well adapted to meet the conditions of practical use.

We claim:

1. In a heel, the-combination of a base, a resilient circular tip to receive the impact with the pavement, an anchorage centrally rotatably securing the tip to the base,a circular series of narrow ridges on the tip in close proximity to each other, said series being concentric with theanchorage, and a plurality of narrow ridges on the base, at one portion only thereof to mesh with ridges rotation accumulate. Preferably on the tip in any angular position 'ofthe latter to prevent unintended rotation of the tip, the portion of'the tip adjacent to the ridges on the base being adapted to be flexed away therefrom to disengage the ridges and permit the tip'to be rotated.

2. A heel comprising a base having an'extended rear edge portion adapted to heremoved by bufiing, said portion having one or more recesses therein tofacilitate the accurate positioning of the heel on the shoe and to indicate the maximum depth of bufiing.

' 3. In a heel, a resilient base for attach? forded between the plate and theshoe on close driving of the nails.

4. In a resilient'heel, a base, a rubber tip to take the impactwith the pavement, the base including a plate having a hole, the tip having an anchorage rotatably securing thetip to the plate, said anchorage comprising a member extending through said hole and having bearing relation therein, the member being headed over the plate, and a washer between the plate and the headed portion of the said member, said washer having snug fitting engagement with the member to pre vent the latter from binding against the plate on being headed over as aforesaid.

' 5. In a resilient heel, a base, a rubber tip,

to take the impact with the pavement, the

base including a plate having a hole, the tip having an anchorage rotatably securing the tip to the plate, said anchorage comprising a member extending throughsaid hole and engaging over the plate, anda washer about the member positioned between the tip and said plate to prevent rubber from being 115 squeezed into said hole. I

6. In a heel, a base having a breast'portion and a seat adjacent to its tread, said seat extending from the breast portion to the rear end of the heel, and arotata-ble tip fitted in said seat and closely contacting the breast portion, said base having a rear edge portion extending beyond the seat and adapted to be removed bybufi'ing, said portion having one or more recesses therein to indicate the maximum depth of buiiing, as set forth.

7. In a heel, a base'having a breast portion and a circular seat adjacent to its tread, and a tip rotatably mounted in said seat in close contact with the breast portion, said breastportion terminating at the sides of the heel in narrow flanges 'proje'cting to- 7 Ward the rear of the heel, the base havmg an edge portion beyond said seat, at the ends of said flanges, said edge -portionbeing" adaptedto be bufi'ed and having recesses therein to facilitate the accurate positioning of the heel on the shoe and to indicate the maximum depth of buffing, asset forth.

8. The herein described method which ineludes forming a projecting portionon the rearpart of the stationary member of am- 7 tatable rubber tip heel, and indicating means r on said portion associated therewith, attaching the heel to a shoe, and buffing said proj ecting portion to the depth indicated by the indicating means.

'9. In a heel, a resilient base for attach-'- '7 ment to a shoe, an anchor plate secured to tion, the plate having holes for nails for fastening the base of the shoe, the tip hava ing holes registering with the holes in the plate, so that the nails may be driven through the registering holes of the tip and s plate, with the heads of the nails engaging the plate in spaced relation to the tip.

In testimony whereof we aflix our-signatures. t
