b, is the tread of variable thickness
the sides of the same of variable depths.
d, is a central elastic support more particularly applicable to large sizes.
e, e, are holes provided in the bottom of the boot or shoe which in some cases I
employ and by means of which communication may be made with the interior of
the boot.or shoe for the purpose of ventilating the same.
f, is a flange or rim by means of which my improved heel may be secured to the
boot or shoe.
g, is the canvas lining used in combination with the india-rubber or other elastic
material by means of which the heel and sole may be more firmly secured to the
boot or shoe.
h, h, are small conical shaped studs or projections of india rubber or other elastic
material provided on the sole by the form and arrangement of which the tread of
the wearer may be distributed and greater elasticity insured.
i, i, are holes provided in the bottom of the boot or shoe which in some cases I
employ and by means of which the communication may be made with the interior
of the boot or shoe for the purpose of ventilating the same.
My improved heel and sole may be secured to the boot or shoe by sewing,
stitching, or by cement or other suitable adhesive composition, or by the combined
use of the same.
Heels and soles as herein described I make wholly of india-rubber or other
suitable elastic material, or of india-rubber or other suitable elastic material and
canvas combined, and in various sizes to meet the requirements of the trade.
The elasticity of the tread of my improved heels and soles when in use, is obtained
either wholly from the elastic nature of the material of which they are constructed,
or partly from the elastic material of which they are constructed, and partly from
the elasticity of the air which may be contained or find its way into the hollow

page_text: spaces. I wish it to be understood however that I do not rely upon the elasticity
of the air, and disclaim any novelty for the employment of air as a cushion or
elastic medium, except in the manner as herein described and set forth.
Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I declare that what I
claim is-
1. In boots and shoes the particular mode of construction, arrangement and
combination of parts comprising a heel with a hollow space or spaces, the walls of
which as well as the tread of the heel are formed of india-rubber or other suitable
elastic material, or of india-rubber or other suitable elastic material and canvas
combined, and made of varying depths and thicknesses, by means of which the
greatest resistance to the weight of the wearer is obtained at the back part of the
heel, where the weight is first received, such resistance gradually reducing towards
the front part of the heel, so as to secure the most effective distribution of the
weight of the wearer in the act of walking or running, combined with the most
effective re-action of the elastic material employed, and likewise to reduce the shock
to the system especially in long marches, in the manner and for the purposes
substantially as herein described and illustrated on the accompanying drawings.
2. In boots and shoes the particular mode of construction arrangement and
combination of parts comprising a sole made of india-rubber or other suitable
clastic material, or of india-rubber or other suitable elastic material and canvas
combined, and provided with studs or projections of elastic material on its inner
surface, by the form and arrangement of which the greatest resistance to the
weight of the wearer is obtained at or near the centre of the sole so as to secure
the most effective distribution of the weight of the wearer in the act of walking or
running, combined with the most effective re-action of the elastic material employed,
in the manner and for the purposes substantially as herein described and illustrated
on the accompanying drawings.
3. In boots and shoes the particular mode of construction arrangement and
combination of parts, as set forth in Claims 1 and 2, as utilised for assisting in the
ventilation of the same, in the manner and for the purposes substantially as herein
described and illustrated on the accompanying drawings.
Dated this 30th day of May 1892.
