RESILIENT HEEL TREAD. APPLICATION man sEPTI 5. 1919.

/l III/. 1f 15 L26 INSIEME-UE ATIUENEY:

. UNITED., STATES .PATENT oFFicE.

ROBERT AItMoUn, :or PROVIDENCE RHODE ISLAND.

` nnsILIENfr HEEL-TREAD.

T0 all 'whom t may] concern.' l

Be it known that I, lROBERT ARMoUR,a native of British India, residing at Providence, in the countyl vof Providence and State of Rhode Island, have invented a new and useful Improvement in Resilient Heel- Treads, of .which the following is a specification.

My invention has reference to an improvement in shoes and the like and more particularly to an improvement in resilient heel treads, for the heels of boots, shoes and similar articles of foot wear.

In the usual construction of resilient heel treads for boots, shoes and the like, the heel treads are either made entirely of-comparatively soft rubberor the like, which is expensive, or a-heel plate kholding soft rubber plugs is used. In the last mentioned form the rubber plugs are not resilient enough,

they are not of the right shape to give the best result and they are so constructed that thevusual wearer or' such plugs cannot readily change them around for uneven wear or replace them when worn out, without the Y use of special tools for such purpose.

The object of my invention is to improve the construction of resilient heel treads,`

whereby the heel treads aremore resilient when in use,the soft rubber-plugs more easily ehanged around for uneven wear on the plugs, the plugs are improved in form and placed more advantageously on the heel for resiliency and wear and when worn out may be easily and quickly removed and a new plug replaced, by hand.

A further object of `my invention is to reduce the cost of such resilient heel treads,

principally by reducing the waste in the soft rubber plugs, when worn out.

Another object of my inventionvis to increase the resiliency of such rubber plugs by extending a cavity in the plug beyond the surface of the plate.y

My invention consists in the peculiar and novel construction. of a resilient heel tread comprising a heel plate, soft rubber oval plugs each having a Vcavity which extends out beyond the face of the heel plate, means for detachably securing the plugs in the plate, means for securing the plate to the heel of a shoe or the like, said resilient heel tread having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a view looking at the sole of Speccationfof Letters Patent.

a shoe V'showing theh'eel provided with myl shoe, 6 a heel plate 7. 7 soft rubber plugs and 78. '8 screws which secure the plate 6 to the heel 5. I

kThe heel plate 6, which may be of metal or other material, has Oval openings 9. 9 with undercut sides 10. 10 which with the bottom of the heel 5 forms oval recesses 11. 11 for the plugs 7. 7 These recesses 11. 11 are placed in the plate two vadjacent and parallel with the back of the heel and one extending in at an angle from each forward Y corner of the heel, in the best possible positions for resiliency. The soft rubber oval plugs 7 7 each have a flat tread 12, straight sides 18. 13, a continuous angular lip 14 which fits Vunder the undercut sides 10. 10 of the openings 9. 9 and detachably secures the plugs in place, and an oval cavity V15, the bottom 16 of which extends beyond the outer face of the heel plate 6, as shown in Fig. 2.

It is a well known fact that there is no resiliency in soft rubber when confined.V When in use the cavities 15. 15 in the plugs extending beyond the face of the heel plate gives all the resiliency possible, the soft rubber lips 14. 14 will give easily in changing, removing or replacing the plugs, `and when the plugs are worn down to the cavities in the plugs, the ring of soft rubber thus left in the recesses in the plate, may be easily removed, with the least possible amount of waste in the rubber plugs.

It is evident that the arrangement of the rubber plugs in the heel plate could be changed and details of construction could be varied within the scope of the appended claim.

Having thus described my invention, I claim as new Y A resilient heel tread comprising a heel plate 6 having two undercut oval openings 9. 9, adjacent to and parallel with the back Vof the lheel plate, an undercut oval opening y Patented June 29,192o-1V y,App'lfieatifm flied september 5, 1919; serialA '110.3219421 the plug, taken lon line 9 extending at an angle from eachv forward corner of the heel plate, soft rubber oval plu 7. 7 in each undercut oval opening v in t e heel plate, each oval plug 7 having a flat headV 12, straight sides 13, 13, a con-Y tinuous angular lip 14 which fits under the Vundercut sides of the openings 9,9 and detachably secure the plugs in place and an oval cavity 15, the bottom 16 of which eX- 10 tends out beyond the outer face ofthe heel down to the heel plate, oval rin s of rubber only are left, which may be easll removed vby the fingers, from the cavities 1n the heel plate.
