HEEL; 1

Application filed June 8,

T 0 all whom it may concern:

Be it known that 1, WILLIAM DAvm S'rEnNBnRG, a citizen of the United States of America,- and residing at 19 City Road,

tially D-shaped carrier and a detachable wearing piece of horseshoe or like shape.

The object of the invention is to provide an improved heel of the above kind, the wearing piece of which may be readily detached and replaced by a new piece, the arrangement being such that when in position the wearing piece is firmly secure against accidental displacement.

According to the invention the wearing piece is provided with a core element adapted to cause the piece to be secured in relation to the carrier.

Further features of the invention will be hereinafter described and defined in the claims. a

The present invention will now be described with reference to the accompanying drawings in which Figure 1 isan inverse lan view of one form of the attachment shown applied to the heel of a boot or shoe; 7

Figure 2 is a sectional view thereof taken on the line 22, Figure 1;

Figure 3 is afront end view of the same;

Figures 4, 5 and 6 are a plan view, elevation and plan view respectively of the parts from which the wearing piece is formed.

Figure 7 is a plan view of a modification;

Figures 8 and 9 are a plan view and sectionalelevation of a further modification;

Fig. 10 is a sectional elevation taken on line 10--10 of Fig. 7, and

Figurell is an inverted plan of a further modification.

Like reference characters represent similar points throughout 'the figures of the draw in s.

The attachment comprises a carrier member or block a of D shape of vulcanite, leather, rubber or any other "suitable material and a wearing member of substantially horseshoe shape I), which may also be of leather, vulcanite, rubber or other 1923. Serial No. 644,234.

suitable material. The carrier, member or block a, is of the same general shape as the heel, but is narrower and shorter in length so that Whenthe' carrier is :placed in posi tion with its inner edgein alignment with the inner edge of the heel of the boot, a space or galleryis left around the side and edge her; The carrier'is secured in the position above-indicated in any suitable manner to the heel c, as for example, by nailing or screwing,'and when secured thereto is, in-

tended to remain'moreor'less permanently in position. I

' The side and outer end edges of the carrier are undercut or bevelled as shown at d, for a purpose which will hereafter appear.

Around the carrier, a wearing piece I) of substantially horseshoe shape is adapted to be fitted.- The wearing piece is provided with'bevelled or inclined inner edges as shown at 7", corresponding with the bevelled or undercut edges (1 on the carrier;

The wearing pieces may be conveniently of the carrierto receive the Wearing memformed from a straight strip orlength of material 9 of the cross-section shown, having a channel, groove or passage extending longitudinally or throughout its length into which is inserted a member or core h,so that when in place in the wearing member the latter is bent into its correct shape. The member or core is preferably of. resilient material, for example, resilient metal, so as to act as a spring to tend to maintain the bevelled portions of the Wearing member and carrier facilitate the latter.

Co-operating means are provided on the wearing member and carrier to prevent the wearing member from creeping or sliding off the carrier and" this may be effected by making the core member of a length of material suchthat when placed in the channel or groove, portions are left that are bent over substantially at right-angles as shown at i, such bent portions"beingiadaptedto in close engagement, and placing of the former on the engage recesses or depressions 2",- in the carrier member. In the form shown in Figures 1, 2 and 3, the ends of the wearing member are provided or formed with slots .or recesses j, that extend inwardly from the inner edge of the wearingmember to the channel there'- in and after the core or retaining member reinforcing plate 0 embedded in the carrier member is provided'extendedto engage recesses 0 in the wearing member, the plate being so arranged that in fastening down the carrier the plate is drawn towards the heel.

In the 'form of the invention shown in Figs. 7 and 10, a modification of the'means above mentioned is illustrated. In this form, in addition'to bending the core member at its ends i to engage depressions 0r recesses in the carrier member, the ends of the wearing member itself are each provided on their inner faces with a protuberance or projection as shown at r,'that-is adapted to enter a corresponding recess Z in the edge of thecarrier member. In this form the engaging surfaces 'ot'the bevelled edges of the'carrier and wearing member may also be ribbed or corrugated as shown at m, 1n order to moreetfectively prevent loosening or'creepage of the wearing member.

Referring now toFigures 8 and 9, there'is shown therein a form of wearing member in which the channel, groove or recess'is located at the lower'end-of the reces'sor slit n, extending'upwardly to the upper surface thereof. This provides'a form in which the core maybe more'readily inserted in the channel, as by spreading-it open at one end, inserting one endot the core and then pressingthe remaining portion ofthe core into the recess. The endsot the core may then be'bent over as shown at 2', through apertures extending from thechannel to the bevelled edge, or such end can be bent'over before placing the'core in the channel or groove. This slit n is also'used with the-forms shown in Figs. 1, 2, 3, 7 and 10, but the slit is not illustrated in Figs. 1 and '7,-to avoid the lia bility of confusion being caused by too many dotted lines.

In the modification shown in Figure 11 I have shown a further embodiment of the means for ?retaining the wearing :piece in plac'ein which projections or 'protuberances at the ends of the wearing piece engage cut away portions or angular recesses in the carrier "In all the modifications described the wearing members may be conveniently formed from a length of material 9 of the cross-section shown by cutting said length into sections of suitable dimensions to form the-individual wearing pieces. This'is particularly advantage'ousinthe case where the wearing pieces are to be formed of rubber as long lengths which may be moulded and then'ciit into sections of the correct length. This provides a'construction in which the carrier has portions or surfaces of increased while the'remainde'r of the heel is compara- I tively little worn.

It will be seen that when said portions have become worn the wearing pieces may be changed from one heel to the other so that the unworn portions will take up the outerposition'in which most wear will take place.

By this transfer method the wearing pieces may be worn down subs'tantially'uni forml-y, consequently increasing the life thereof to a considerable extent. 7

The carrier in the foregoing specification has been described as 'an attachmenta'tor a' heel after the boot or shoe has been "manufactured, the carrier, however, may be formed during manufacture as an integral part of the'heel of the boot or shoe and series or set of spare wearing pieces for application in place of the original one supplied when the latteris worn. In this case the carriermay benailed,,sewn or otherwise secured in position as an'integral-part of the remainder of the heel.

Having now described my invention what I claim asnew and desire to secure by Letters Patntisa- 1. A heel for boots and shoes including a carrier element,a wearing member of-substantially horse-shoe shape eiztending around the sides and the outer end of said carrier element, the carrier element being recessed, a resilient horse-shoe shaped core member embedded in said wearing member, and lugs at the ends of one of said members extending into the carrier element recesses, said core-and lugs detachably locking the war- '5. A heel for boots and shoes including a carrier element of substantially D-shape ar ranged at the lower end of the heel and provided with beveled side and rear surfaces, a. Wearing member of substantially horseshoe shape extending around the side and rear edges of the carrier element and provided with an inner beveled surface en- 3 gaging the beveled surfaces of the carrier clement, said carrier element having recesses at the opposite sides of its front end, and a substantially U-shaped resilient-metal core member embedded in the Wearing member and having inwardly extending lugs at-its ends engaging the recesses of the'carrier ele- V ment for locking the Wearing member in position.

In testimony whereof I have signed my
