CAMERON WALKER 7 Colston Parade, Redcliff Bristol Insurance Agent do
hereby declare the nature of this invention to be as follows:-
The boots, shoes and the like will be made with a larger upper (than is usually
used in making boots & shoes) allowing a space of one inch, more or less, between
the sole of the foot, of the wearer, and the inside sole of the boot, shoe or the like.
In this space is a pneumatic bladder (made of india-rubber or the like) (covered
or uncovered) fitted with a tube which projects through the boot or shoe. The
tube may be fitted with a safety valve or not so, and may project at the back, side
or sole of the boot or shoe.
Thus the pressure of the air in the pneumatic appliance can be regulated from
the outside while the boot or shoe is on the foot.

I, CAMERON WALKER 7 Colston Parade, Redcliff, Bristol Assurance Agent 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:-
Boots, shoes, slippers and all foot coverings fitted with a pneumatic appliance
or bladder or tube, fitted either between the sole of the foot and the inside sole of
the boot or shoe, or fitted between the soles of the boot or shoe, or fitted on the
outside sole of the boot or shoe, either the full length and breadth of the sole, or
half the length or less or more.
Boots or shoes, (fitted with a pneumatic appliance between the sole of the foot n
and the inside sole of the boot or shoe) Fig. 1. & 2. may be made with a large
upper a on a large last, so as to allow a space 6 of one inch (more or less, according
to the size of the pneumatic appliance c to be fitted in) between the sole of the
foot n and the inside sole of the boot or shoe, (see drawings Sheet 1.) Fig. 2.
Figure 1 is a side elevation of a pneumatic boot.
Figure 2 is a section of a pneumatic boot.
Figure 3 is a pneumatic bladder as used in Figures 1 and 2.
Figure 4 is a section of a pneumatic running shoe.
Figure 5 is a pneumatic bladder as used in Figure 4.
Figure 6 is another pneumatic bladder.
Figure 7 is a section of a pneumatic boot.
Figure 8 is a cross section of a pneumatic boot.
A pneumatic appliance or bladder c made Fig. 3. of thin sheet india-rubber,
(such as is used for making football bladders) or any suitable material, made the

page_text: shape of the inside sole of the boot or shoe, made to occupy the space 6 of one
inch (more or less) in thickness (when inflated) according to the space & allowed in
the boot or shoe; said pneumatic appliance or bladder c is fitted or placed inside
the boot or shoe; said pneumatic appliance or bladder e may be made either
square, oval or any such shape at the sides, ends or edges and may be fitted with a
small tube d connected with said pneumatic appliance or bladder e for inflating
purposes.
Said tube d may be fitted in any position to the pneumatic appliance or
bladder c so as to remain inside the boot or shoe, or said tube d may be fitted
in any position (and a hole made in the boot or shoe) so that said tube d may
project through the boot or shoe at the back, side, toe or sole or any position
suitable, so that said pneumatic appliance or bladder e may be inflated from the
outside after the boot or shoe is on the foot without taking said boot or shoe off
the foot, and said tube d may be tied in the inside or the outside, (according to
position) of the boot or shoe, with cord or the like to prevent the escape of the air
from said pneumatic appliance or bladder c. Or said pneumatic appliance or
bladder e may be fitted with a safety valve e (with or without small connecting
tube d) fitted in any position inside the boot or shoe or fitted so as to project
through the boot or shoe) through a hole in the boot or shoe made for that
purpose) at any position so that the pneumatic appliance or bladder c may be
inflated from the outside after the boot or shoe is on the foot without taking said
boot or shoe off the foot. (See drawings Sheet 1.)
The boots, shoes and the like may be made in the ordinary way i.e. machine or
hand stitched or riveted or pegged, and may be fastened on the foot by laces straps
or any of the like methods, and be made of leather or any suitable material made
with a larger or smaller upper a according to requirements.
The pneumatic appliance or bladder e may have a cover, made of leather, canvas
or any suitable material to strengthen or protect it and said pneumatic appliance
or bladder c may be fastened to the inside of the boot or shoe, by one piece or
strips of leather or tape or the like material and may be tied or fastened in the
inside of the boot or shoe, or the ends of said fastening may be passed through
holes (made for that purpose) in the boot or shoe and tied on the outside.
The projecting tube d or valve e may be covered or protected by a cover
or cap made of leather or the like material. (See drawings Sheet 1.).
Half-sole pneumatic boots or shoes Fig. 4 or any foot coverings, may be made in
the same way and have the same descriptions as the full-sole pneumatic boots or
shoes Fig. 1(as previously described) only having a half-sole Fig. 5 & 6 (more
or less) pneumatic appliance or bladder g, fitted in them, said pneumatic appliance
or bladder may be made and fitted to occupy the front half or the rear half or
any such position in the boot or shoc and be one inch (more or less in thickness)
and may be fitted with a small tube d or small tube d and safety valve e and said
tube d may be placed inside the boot or shoe or to project through the boot or
shoe, and may be covered and protected and may be fastened as in the case of the
full-sole pneumatic boot or shoe (previously described). (See drawings Sheet 2.)
Boots, shoes, slippers and all foot coverings fitted with pneumatic appliance or
bladder or tube c between the soles of said boot or shoe or the like. Fig. 7 & 8.
A boot or shoe may be made in the ordinary way, that is the upper a, insole
and welt i sewed or secured together, then a strip of leather ; or any suitable
material one inch broad (more or less) and the length of the circumference of the
sole of said boot or shoe; said strip of leather is then stitched or fastened to the
welt i (all the way round said boot or shoe) pointing downwards so as to form a
cavity & under the insole A of said boot or shoe; then a sole k and heel of leather
or any suitable material is stitched or fastened to the bottom edge of said strip of
leather (all the way round) thus forming a cavity b or space between the insole
and the sole k and heel 1. Fig. 7 & 8.

The ends of said strip of leather may be left unfastened and may be fastened
by 'a cord or lace passing through holes made for that purpose in said strip; or

page_text: welt i or sole k. Said strip ; may be fitted so as the ends would meet at the back,.
toe or side of the boot or shoe thus having the opening (formed by the ends of the
strip of leather j) at any position you may previously desire, before said boot or
shoe is made.
Into the cavity b between the soles h & k of said boot or shoe is fitted a
pneumatic appliance or bladder or tube made or fitted either to occupy the whole
or less of the said cavity b, and may be fitted with a small tube d or a small tube-
and a safety valve e, so as to remain inside the cavity bor said tube d or tube with,
valve de may project through said strip of leather; at any position or project.
through the sole k or heel or any position so that said pneumatic appliance or
bladder c may be inflated from the outside, and said pneumatic appliance or
bladder c may have a cover for protection, and the projecting valve e inay have a.
cap 1, as described in the full-sole pneumatic boot. (See drawing Sheet 3.)
Said pneumatic appliance c or g may be made and fitted into a stocking or sock
by simply placing it therein, or said pneumatic appliance or bladder or 9 (with or
without cover) may be fastened to the naked foot or clothed foot by straps or
tapes or any such method.
Having now particularly described and ascertained the nature of my said inven--
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. A one-cell air chamber or bladder or pneumatic appliance which may be fitted.
in or to running, walking, cycling, football or any boot, shoe or foot covering.
2. A pneumatic appliance fitted to boots, shoes or the like which may be
attached to or removed from said boot or shoe as desired.
