Improvements in and relating to Pneumatic Tyres for Wheels.
WILLIAM HENRY HANSON 35 East Ferry Road Poplar London E. Engineer
do hereby declare the nature of this invention to be as follows:-
tyre.
My invention consists of a means of securing and joining the inside edges of a
pneumatic tyre used for vehicles. To obtain this I grip their edges and hold them
together by the flanges of the wheel which is made in two equal halves or discs of
any suitable metal and bolted or pinned together at their outer edges. I make the
wheel when joined together to have its rims to suit the shape and diameter of the
Before gripping the tyre edges within the wheel discs I insert a thin strip
of brass or any suitable metal in the form of a ring so angled or shaped to suit the
size and shape of the inside edges of the wheel discs and in making my tyre of
layers of canvas I line the inside with a rubber layer, the rings previously described
being placed between the canvas and rubber and when gripped by the wheel discs
form an air tight tube or tyre, without the usual separate bladder or inner tube.
On the periphery of the tyre and between the canvas and the outer covering or
strip I lay a thin strip or band of brass or other metal of any desired width this
strip or band is indented at close intervals with oblong, round nosed or other shaped
indentations, these indentations being made alternately from either side thus
preventing puncture, side slip or creeping of tyre. I secure my valve for inflation
by bolting throught the rim of the wheel with washer on the inside to fit the shape
of the wheel and a nut and check on the outside of the rim.

WILLIAM HENRY HANSON 35 East Ferry Road Poplar E. Engineer 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 pneumatic tyres for application to cabs, omnibuses or
other carriages including cycles and consists of a wheel constructed with or without
spokes. In the latter case I make my wheels in two halves or discs of suitable
metal the rims of which sustain the air chamber. These discs or flanges may be of
stamped steel or malleable iron or any other suitable metal. My air chamber
consists of layers of canvas or any non expansive fabric with a lining of india
I grip the
rubber, cemented or amalgamated together or made separate as desired.
inside edges or necks of the air chamber by the discs or flanges as illustrated and
described by drawings annexed. I do not use an inner tube for inflation separate
from the outer covering as has been hitherto the practice, this being obviated in my
invention by the joining or holding together of the edges or necks of the chamber
by the discs or Hanges. To obtain a large air capacity as for example in an
omnibus wheel I make my discs or flanges of stamped steel or malleable iron with
strengthening ribs from the hub to the edge of the rim and bolt or otherwise secure

page_text: the two together as close to the hub as is practicable. In my cycle wheels with
spokes I make the rims in two halves with bolts or pins to hold together and use a
flat ring with slots to correspond to the bolts or pins used, the said slots having on
either side an inclined plane which fits immediately beneath each bolt or pin head,
any increasing twist or movement of this ring tightens the rims or flanges of the
wheel. I invert the inner edges of these flanges or rims either externally or
internally to take the ends of the spokes. The hub of the wheel I make in two
pieces by having a socket arrangement in the middle so that in detaching the air
chamber by unlocking the flat slotted ring I can spring the spokes back and thus
facilitate the method of-say repairing any defect of the air chamber. Referring
to the annexed drawings Fig. 1. is a half section of tyre B. showing the india

the bolts S. T. is a protection piece or tyre of india rubber. The valve V. is
bolted through the flange D. and secured by a check nut N. A represents a thin
sheet of metal in the form of a ring which is inserted between the india rubber and
canvas at the gripping edges of the air chamber. Fig. 2. illustrates a half section

Having now described and particularly ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
my claim is.
(1.) A wheel for cycles, cabs, omnibuses and other vehicles consisting of a
chamber filled with compressed air and gripped or held together at the edges or
necks by suitable flanges or discs substantially as set forth.
(2.) A wheel for cycles, cabs, omnibuses and other vehicles consisting of a
chamber filled with compressed air and having thin strips of indented metal
inserted between the outer canvas and rubber tyre substantially as described.
(3.) A wheel for cycles, cabs, omnibuses and other vehicles consisting of a
chamber filled with compressed air and without the addition of a separate inner
tube for inflation.
