Improvements in Pneumatic Soles for Boots and suves.
I, ARTHUR GILPIN BILL, late of 65, Paynes Lane, and now of 13, St. Nicholas
Street, Coventry, Grocer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to boots and shoes and consists essentially in providing
boots and shoes with pneumatic soles which may be readily attached and detached
as required, one method of carrying out my invention being hereinafter described
with reference to the accompanying drawings wherein,
Fig. I is a side. elevation of a complete shoe constructed according to my
invention.
Fig. II is a similar view showing the pneumatic sole partly detached and the
bladder partly withdrawn.
Fig. III is a sectional elevation of the said shoe showing the bladder in place
and inflated.
Like numerals indicate like parts throughout the several views.
In carrying out my invention according to the method exemplified in the draw-
ings, I construct the shoe with a wide welt 2 and perforate the same at intervals
to receive the lacing 3 which also passes through a series of holes 4 in a detachable
casing consisting of a false sole 5 and a flexible wall 6 of leather, rubber and
canvas or other suitable material or materials. The casing is adapted to receive
the air-tight india-rubber or other suitable bladder 7 which is provided with any
convenient form of valve 8. The said valve 8 may be adapted to provide for
deflation as well as inflation of the bladder and preferably projects out through an
aperture 9 in the back of the wall 6, as shown.
For use, the bladder 7 is placed in the casing 5, 6 with the valve 8 projecting
through the aperture 9. The casing is then laced to the west 2 of the shoe proper

and the wearer being supported on the compressed air in the bladder is consider-
ably assisted in locomotion, and is saved from concussion, vibration and shocks.
In the event of accidental deflation or for other reasons, the wearer can detach
the pneumatic sole and use the shoe by itself as an ordinary shoe when desirous of
doing so.
Though I have only described one method of carrying out my invention, I do
not wish to confine myself thereto, as the same result may be obtained in various
other ways.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. An inflatable bladder and a cover or casing adapted to receive such bladder
and to be detachably attached to a boot or shoe, for the purpose set forth.
2. The combination of a boot or shoe, a pneumatic sole, and means for detach-
ably securing the one to the other.
3. A boot or shoe having the sole perforated round the edges, a detachable
cover or casing consisting of a false sole and a flexible perforated wall, and adapted
to receive an inflatable bladder, and, a lacing adapted to be passed through the
respective perforations, substantially as and for the purpose set forth.
4. A pneumatic sole for boots and shoes constructed, arranged and adapted to
be operated substantially as herein described and as illustrated in the accompany-
ing drawings.
