Anti-concussion Heel and Sole.
1, LESLIE ROGERS, Tea Planter, resident of Dehra Doon, India, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described, and ascertained in, and by the following
statement:-
I describe my invention as follows: It is a pliant and flexible heel and sole in
one, or heel separate without the sole, made of india rubber, gutta-percha,
caoutchouc, or any like springy material. The above heel and sole can either be
simply inserted into the boot, or fixed into the boot in the manufacture of the
latter.
It is called the "Anti-concussion heel and sole," and as its name implies, its
object is to protect the wearer from every form and feeling of concussion of the
foot, and consequent fatigue, when walking, running, jumping, dancing, skating etc.;
and in fact, in all cases of active movement where the feet come in impact with
anything hard and unyielding.
It is my belief, that fatigue, that is the result of much walking, running,
jumping, etc. is to a large extent caused by the vibrations produced on the brain, by
the constant concussion of the feet on the ground.
The harder the ground, the heavier and more unyielding the boots worn, or the
weaker the physique of the wearer, the more jarring the concussions transmitted
to the nerve centres, and therefore the more rapid the subjection to fatigue.
My invention claims to obviate this natural disadvantage to a very appreciable
extent by minimising the concussions, and thereby indefinitely postponing the sense
of fatigue.
The above result is obtained by the application of hexagonal, or any other
shaped air-cells, as cushions, under certain parts of the foot, in my artificial rubber
heel and sole. But it must be understood that I do not confine myself to the
particular arrangement of cells here described, which may be varied in shape and
position without departing from the essence of the invention.
The drawings show the upper, and right surface (Fig. 2); and the reverse or
under surface (Fig. 1) of the whole sole, and also both sides (Figs. 3 & 4), as well
as side views (Figs. 5 & 6) of the separate heel.
The upper surface will be nearly smooth, while the under part will have the cells
open as shown in the drawings, or entirely closed.
The drawings attached clearly show the nature of my invention, but of course,
the artificial heel and sole, will be manufactured of various thicknesses and sizes, to
suit different purposes, and all kinds of feet.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim to be novel, and therefore desire to protect, is as follows, viz. :—
The use of air-cells (open on one side, or entirely closed up) in my previously
described artificial rubber heel & sole, to act as cushions under certain parts
of the foot. The said artificial heel and sole, being either separately inserted into
the boot, or fixed into the boot in the manufacture of the latter.
