PROVISIONAL SPECIFICATION.
Metal Protected Pneumatic Tyres.
I JOHN IGNATIUS BOLTON of 19 Norton Road Hove in the County of Sussex
Electrician do hereby declare the nature of this invention to be as follows:-
I construct of indiarubber and metal a durable pneumatic tyre, suitable for
vehicles bicycles and other machines. I take an indiarubber tube which I inflate
with air, which I then stretch or otherwise fix in and around, the hollow rim of a
wheel.
"
I then take a piece of very thin sheet metal (by preference steel) which I cut
in lengths of any width, I may require, I then punch rows of small holes along
cach side of the metal, generally, a quarter to one inch apart allowing a margin on
each side of any width I may require I then cut the metal from one row of holes
into the other's These cuts I generally make straight, slanting, or curved, after
which I cut the metal into shorter lengths These pieces I call bridges I then
take these bridges and bend them round over the pneumatic tube, from one side to
the other fixing them to the rim of the wheel by any sutible means allowing the
small holes on each side of the bridges to come a little above the rim of the wheel
I then take a length of indiarubber which I call a cover on or near the edge of
this cover I insert or otherwise fix strips of very thin metal by (preference steel)
I then place the cover round over the small bridges allowing the metal strips in
the cover to come round and cover the small holes on each side of the bridge's
after which I fix the cover by any suitable means to the rim of the wheel, and the
improvement and advantage of this my invention are these That by covering the
pneumatic tube with metal as discribed it is not so likely to be cut punctured or
damaged as those at present in use.

COMPLETE SPECIFICATION.
Metal Protected Pneumatic Tyres.
I JOHN IGNATIUS BOLTON Electrician of 131 Sackville Road Hove in the
County of Sussex 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. Figs. 1 & 7 as shown in accompanying drawings is an ordinary steel wheel
rim H Figs. 1 and 7 is a piece of canvas attached round the rim of the wheel
L Figs. 2 and 7 is a piece of indiarubber placed in and around the rim of the
wheel and which is attached with rubber salution to H Figs. 1 and 7 G Figs. 3 and 7
is a piece of indiarubber F Figs. 3 and 7 is a piece of canvas attached round the
indiarubber G. Figs. 3 and 7 by means of rubber salution I then take F and G.
Figs. 3 and 7 and place them in and around the rim of the wheel fixing them to L
Figs. 2 and 7 with rubber salution E Figs. 4 and 7 is an indiarubber tube inflated
with air in the ordinary way D Figs. 4 and 7 is a piece of canvas attached round
the indiarubber tube E with rubber salution I then take E and D Figs. 4 and 7
and place them in and around the rim of the wheel attaching D to F by means of
rubber salution C Figs. 5 and 7 is a piece of metal by preference steel rolled
into required shape, it is then placed on a templet and a row of small holes punched
along the sides from a to an inch or more apart according to the size of the tyre.
and weight of the machine, after which the metal is cut through from one hole into
DO77

page_text: the hole on the opposite side the thickness of the metal being adapted to the weight
of the machine.
I then take this metal cover and place it over the canvas D Figs. 4 and 7
allowing the ends to come down and rest in between the canvas F and F Figs. 13
and 7 the small holes in the metal cover coming a little above the rim of the
wheel and the canvas H Figs. 1 and 7 This metal cover may be made in 2 3 4
or more sections the ends overlaping each other when placed on the tyre
C is a side view of the metal cover shows a section of the same A A Fig. 6
and 7 is an outside graduated covering of indiarubber K K are small pieces of
metal attached on and around the inside of the indiarubber cover A A being placed
so as to come over and cover the small holes on the side of the metal cover C.
B Figs. 6 and 7 is a piece of canvas attached to the inside of the indiarubber A A
with rubber salution J. J. Fig. 6 and 7 are pieces of canvas attached to the
outside of the indiarubber A. A by means of rubber salution.
I then take the parts A A. B. KK. and J J. and place them over the metal
cover C Figs. 5 and 7 I then secure the whole to the rim of the wheel by attaching
the canvas B Figs. 6 and 7 to canvas H Figs. 1 and 7 by means of rubber salution
The canvas pieces J J Figs. and 7 overlaping each other and being attached
together in the same way.
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
caim is
Firstly. The metal protector or cover C which prevents the inside air tube E
Fig. 4 from being punctured or otherwise damaged.
Secondly. The metal parts KK inserted between the indiarubber A A and the
canvas B.
Thirdly. I wish to point out that the canvas and rubber parts are old I claim
however the combination of my tyre as a whole to be an improvement upon those
in present use.
