To all whom it may concern:
Be it known that I,-ALoi izo E. LEWIS,OIE
Ingersoll, in the county of Oxford, inthe,
Provinceof Ontario, Canada, a subject of the King ofrGrreat' Britain, haveiinvented certain new and useful Improvements in Resilient Heels,of which the followingis a specification.
This invention relates to the heels of boots and shoes, and my object is to produce a heel which will be more. elastic than the ordinary rubber heel without the sacrifice of strength and durability. I attain my object by with an internal spring cushion and means for distributing the pressure of the cushion so that there is no localized pressure below j the wearers heel, and no concentration of wear at the middle of the tread surface of thejboot heel.
The invention is hereinafter more specifi-j. cally described and is illustrated in the ac companying drawings in which-- 3 7 Fig. 1 1s a longitudinalsection of part of the shoe with my lmprovedheel 1n posi- Fig. 3 a plan View showing a modification.
I; In the drawings like numerals of reference,
indicate corresponding parts in the different figures.
fl is a heel preferably formed of a'rubber' compound or other relatively soft and resilient composition, which is securedto the leather lift 2' of the shoe by the nails 12 and washers 13 which are embedded in the rubber at a level above that of the bottom of the recess 3. Centrally of this heel is formed a sarinw cushion which isada ted to bear against the rubber heel, and also against the lift of the heel 2 ofthe' shoe.
By the substitution of an elastic cushion for.
. the solid rubber of an ordinary; rubber heel a much greater degree of resiliency is maintamed than 1s possible wlth such heels withv out sacrificing any of the wearing qualities. This cushion ispreferably formed as follows. A-recess 3 is formed in the heelex-l tending partway down from thetop there- Application filed Ju1y 18, 1921. Serial no.4aa520.
.of. In thisrecess is'located a coil spring 4 against the shoe heel 2 To distribute the pressure, itis preferable to mold in the rubber heel, at thefbottom of the recess, a th n metal Jplate,5,;and asimilar metal plate '6 is provided against the upperend of the coil spring bearing. It is also preferable to recess th hel 2 to partly receive the coil spring 4, as thisl way a longer and there fore a more equably acting coil spring may. bev employed. While If prefer to use one I I spring, yet a plurality of recesses and a pluproviding the heel rality of springs may be employed as indieatedin Fig. 3, and such a construction" would fall within the scope of my invention.

bination of' a leather heel rubberflheel below the leather heel forming the tread 'por-, tion of the heel, a cylindrical recess being formed partly "in the rubber. and. partly in the leather;'means securing therubbe'r heel to the leather engaging the rubber heel above the levelof the bottom of the recess; a coil spring. fitted in said recessand substantially 1 filling the same; a circular metal plate; and
a pressure distributing plate fitted over the 7 upper end of the spring.
2. In" a heel for boots'and and partly in the leather; means securing the rubber heel to the leather engaging the ruba ber heelabove the level of the bottom of the recess and a coil spring fitted in said, recess and substantially fillin the same.
