PROVISIONAL SPECIFICATION.
Improvements in the Material and Construction in Pneumatic Tyres.
I, ARTHUR MALTBY, of 8 Hanover Place, Upper Baker Street London, in the
County of Middlesex Army Tailor do hereby declare the nature of this invention
to be as follows
-
My invention relates to the adoption of specially prepared kid or similar leather,
and horsehair, in the construction of pneumatic tyres.
In carrying my invention into practico I take an air tube of the ordinary form,
mude of kid, rubber, or rubber and silk combined, or other textile fabrics combined
with rubber, over which I place a pocket outer wrapper or jacket of woven cloth
made of horsehair, and with an extra thickness or two on tread of same material
forming a band to prevent punctures. Over the said pocket, outer wrapper or
Jacket I place a cover of specially prepared kid; for rough roads I place on the
outside a tread of rubber or similar material. I attach the outer wrapper or cover
to the rim by means of one, two or three convolutions of a woven cord of horsehair,
made endless or the ends connected together by a steel fastening. I sometimes use
catgut in the same manner, or it can be fixed to the rim by any present known
mode of fastening.
1 sometimes use rubber in connection with the horsehair fabric in place of leather,
and in single tube tyres I use the woven horsehair embedded in the rubber, or
sometimes in the construction I uso canvas with the kid in place of horsohair, and
when I make a single tube tyre with kid I take the skin and solution on the back
rubber and silk, or rubber and canvas, or rubber and horsehair combined. The
object of my invention being to obtain a tyre which cannot be easily punctured and
is very fast and less weight than any other tyre in existence.

COMPLETE SPECIFICATION (AMENDED).
Improvements in the Material and Construction in Pneumatic Tyres.
I, ARTHUR MALTBY of 8 Hanover Place Upper Baker Street London in the
County of Middlesex Army Tailor 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 :-
My invention relates to the adoption of specially prepared shin or kid leather, in
the construction of pneumatic tyres.

page_text: .
In the accompanying drawing Fig. 1 is a longitudinal section through a tyre at
the place where the valve is situated.
A is the au tube of the ordinary form, made of skin or kid prepared as heremafter
described. B is a pocket or outer wrapper or jacket made of horsehair and cotton
fabric material which is elastic in the direction of the circumference of the wheel but
not when inflated elastic in the cross direction The pocket B may have an extra
thickness or two of the same material concentric with the tread part of the tyre
forming a band (not shewn) to prevent punctures Over this pocket or wrapper Bis
placed a cover of the specially prepared kid or thin skin that is to say stretched
and rendered waterproof. For rough roads I place on the outside of this cover a
tread of rubber or similar material. In order to be able to remove the air tube A
in case of puncture I leave one or more openings in the pocket B, and in order to
prevent a bulging of the tube A at these places I strengthen the said tube by means
of a stocking D around it and somewhat longer than the opening as is well understood.
The openings may be at the side or between the tyre and the rim. In order to make
a detachable tyre I attach an ordinary open cover to the rim G by means of one two or
three convolutions of catgut specially prepared that is to say stretched so as to be
non-elastic, and with the ends hooked together by a fastening similar to a lathe cord
fastener, which will enable it to be tightened and adjusted as to length, but other
forms of detachable fastening may be used.
Sometimes I use canvas B with the kid or skin A' inside as shown in Fig 5
place of the horsehair fabric and cover the canvas with another covering of the
skin or kid A or I make a single tube tyre with the skin or kid A as shown in
Figure 6 and I then solution on the inside of same the airproof kid or skin and
Canvas
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 I am
aware that it has heretofore been proposed to employ a canvas pocket or lining
solutioned to a rubber cover and provided with one or more slits or openings with
cross lacing a sleeve being at such place or places mounted to slide over the air tube
and I only ela such arrangement in connection with the use of the prepared skin
or kid for wrapper and air tube, whereby I obtain the advantage of greater lightness,
but what I claim is
-
1 A pneumatic cycle tyre having an inner air tube of kid or skin prepared as
described, and a wrapper or pocket made of the heroin described material and having
an outer cover of prepared skin with or without a rubber tread, the wrapper having
one or more holes for removing the air tube, and the latter in such place or places
being provided with a stocking to prevent bulging, substantially as set forth
'
2. In combination with an an tube of kid or skin prepared as described and a
wrapper or pocket with one or more holes for removing the air tube thorethrough,
a stocking on the latter to provent bulging.
3. A single tube tyre made as described.
