I, JOSEPH HENRY GOODWIN, of Allison House, Sutton-cum-Lound, in the County
of Nottingham, Steel Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
The object of my invention is the prevention of collapse or deflation conse-
quent on punctures in carriage vehicle bicycle and all other pneumatic wheel
tyres where india rubber composition or other material is used.
This object is attained by embedding or placing inside the india rubber or
other tyre a hardened and tempered steel hoop flat, crescent or other section
of steel so as to protect the inner air tube and prevent the collapse of the tyre
to which same has been applied in the event of puncture of the india rubber or
other material of which such tyre is composed.

Improvements in or relating to Pneumatic Tyres for Bicycles and
other Road Vehicles.
I, JOSEPH HENRY GOODWIN, of Allison House, Sutton-cum-Lound, in the County
of Nottingham, Steel Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement; -

object is attained by embedding or placing inside the india-rubber
other tyre, a hardened and tempered steel hoop flat crescent or other section
of steel so as to protect the inner air tube and prevent the collapse of the tyre
to which same has been applied in the event of puncture of the india rubber or
other material of which such tyre is composed. The steel hoop or band is
fastened together by rivets or steel plate and rivets.

page_text: Figure 1 of the drawings show a section of a bicycle rim and tyre with my
improved puncture proof arrangement in position. "A" is a ring of steel
encased in rubber "B" which prevents the steel from cutting the inner or outer
tube.
Figure 2 shows the puncture proof arrangement fitted up as it actually is
in position and with the ends joined together.
Figure 3 shows the method of joining the ends of the steel ring this joint may
also be wrapped with canvas to protect the outer and inner tubes of the tyre.
Figure 4 shows an alternative shape of the steel ring being bent to the same
radius as the inner tube of the tyre.
Figure 5 shown an enlarged section of the puncture proof arrangement. This
is exactly the same as shown in Figure 1 but enlarged to show more clearly.
The hardened and tempered steel hoop or band makes the outer cover of india
rubber or composition tyre independent of puncture inasmuch as if the outer
cover of india rubber or composition tyre is punctured it will not deflate as the
puncture will not pierce to the inner tube owing to the intervention of steel and
rubber combined. which is placed between the outer cover and inner tube and so
prevents any deflation.
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. That the hardened and tempered steel hoop or band makes the outer cover
of india-rubber or composition tyre independent of punctures inasmuch as if
the outer cover of india-rubber or composition tyre is punctured it will not
deflate.
2. The hardened and tempered steel hoop or band under the outer case of
india-rubber or composition gives more resiliency to the wheel and thereby
makes the carriage move more evenly, for example, in going over a stone on a
road the vibration of the carriage is less and on a bicycle the vibration of the
handle is less.
