Improvements in and relating to the Tyres of Wheels for Cycles and
other Vehicles.
I, WILLIAM HEALE, of 193 Battersea Park Road, Battersea, in the County of
Surrey, Chemist, do hereby declare the nature of'this invention to be as follows:-
My invention relates to an improved method of attaching pneumatic or air tyres
to the rims of the wheels adapted to carry them, and it has for its object, facilitating
the repair of the air chamber of the tyre should it be punctured or otherwise
damaged.
I take a pneumatic tyre of the ordinary type consisting of an air chamber fitted
with any suitable form of valve for the purpose of inflation, of a cover of canvas or
other suitable material for the air chamber and preferably having a continuous
sewn seam, and of an outer cover of rubber strengthened if necessary by an inner
lining of canvas or other suitable material. The rim I use may be hollow or solid
but it is preferably made as flat or shallow as possible, and it has formed on its
outer edges beads or their equivalents, breaking the flat or cylindrical surface of
the rim adapted to receive the tyre. To this rim is attached by a central band of
wire, or its equivalent, a band of canvas or other suitable material of a breadth
approximate to that of the rim. The band of wire or its equivalent is then covered
by a narrow strip, of canvas or other suitable material.
To fix the tyre to the rim I proceed as follows;-Having inserted the air
chamber in its canvas cover I lay it round the rim. I then take the outer rubber
cover and lay it over the air chamber which is as yet uninflated.' I'then pass the
edges of this outer rubber cover between the edges of the metal rim and those of
the band of canvas attached thereto, and cement the three together, that is, the
inner surfaces of the edges of the outer rubber cover to the canvas band attached to
the rim, and the outer surfaces of the edge of the said outer rubber cover to the
outer surface of the metal rim. The tyre is then inflated by means of the valve
when the pressure of the air chamber binds the interlocking edges of the outer
rubber band, and the canvas band attached to the rim, firmly to the said rim, the
beaded edges of which tend to keep the parts together.
It will be seen that as no part of the tyre or its fixings is in contact with the
inner surface of the rim, the tyre is practically self-contained, and that the air
chamber can easily and readily be got at for repair by releasing the air from the
air chamber and breaking the joint of the outer rubber cover with the tyre and its
band of canvas, which is easily effected when the tyre is not inflated.

0 Improvements in and relating to the Tyres of Wheels for Cycles and
other Vehicles.
I WILLIAM HEALE of 193 Battersea Park Road, Battersea, in the County of
Surrey, Chemist, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
5 in and by the following statement :-
My invention relates to an improved construction of pneumatic or air inflated

page_text: tyre, and to an improved method of attaching such tyres to the rims of the wheels
adapted to carry them, and it has for its object, facilitating the repair of the air
chamber of the tyre should it be punctured or otherwise damaged.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing in which, Figure 1 is a
view in transverse section showing the construction of my improved tyre, and
Figure 2 is a view in transverse section showing the tyre complete. Throughout
these views similar parts are marked with like letters of reference.
The rim A of the wheel is preferably-though not necessarily-of a flat crescent
section, either solid or hollow and of a size proportionate to the tyre it is intended
to carry. On to the concave side of the rim A is attached a strip of canvas, or
similar material B, of a width about equal to that of the rim. This strip B is
attached circumferentially to the centre of the rim by a band C of wire or other
suitable metal or material, or it may be fixed to the rim in any other suitable and
convenient manner so long as its edges are free. The rim is preferably provided
with a central circumferential depression as shown by the accompanying drawing
for the binder C to lie in.
The outer cover or sheath D is of the ordinary and well-known type, but instead
of its edges being attached to the rim A. direct, they are cemented on the under-
sides of the strip B attached to the rim A, the one edge being shown in Figure 1
of the accompanying drawing so attached, and the other not attached. The air
tube E is of the usual and well-known type and is provided with any suitable non-
return valve passing through the rim A-for the purpose of inflation. The canvas
tube F encircling the air tube E is made out of a strip of material by sewing the
edges together at about half an inch or so from the extreme edges, the said edges
being left loose. This canvas tube F is so located round the air tube that its seam
is in close proximity with one edge of the canvas strip B as shown by the
accompanying drawing.
To get at the air tube for the purpose of repairing a puncture or other damage,
the air tube is deflated and one side of the outer cover or sheath D is detached
from the edge of the strip B to which it is attached, which lays bare the seam of
the canvas tube F. This seam can then readily be opened with a knife or pair of
scissors, laying bare the air tube. The puncture or damage being repaired, the
seam of the canvas tube F is sewn up and the edge of the outer cover or sheath D
cemented to the edge of the strip B, when the tyre is ready for use again.
It is found in practice that the pressure of air inside the tyre is sufficient to keep
the tyre in contact with the rim at the edges thereof, the pressure tending to bind
the edges of the outer cover D between the edges of the strip B and the rim A.
To assist this grip I sometimes form beads on the edge of the rim by turning over
the metal at those parts, and as a further safeguard, if desired, the parts of the
outer sheath or case D in contact with the rim A may be cemented thereto.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore set forth and illustrated by the accompanying
drawing, but hold myself at liberty to make such changes and alterations as fairly
fall within the spirit and scope of my invention.
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 what I
claim is :-
1st. In a pneumatic or air-inflated tyre the combination with the rim of the wheel,
of the strip of canvas attached to the said rim by a central band, and of the outer
cover adapted to be attached to the said strip of canvas, as set forth.
2nd. In a pneumatic or air inflated tyre the combination with the rim of the
wheel, of the strip of canvas attached to the said rim by a central band, of the
outer cover adapted to be attached to the said strip of canvas, and of the canvas tube
having a longitudinal seam located at one side, as set forth.
3rd. The combination with the outer cover of a pneumatic or air-inflated tyre, of

page_text: a strip of canvas or other suitable material attached centrally to the outer or concave
face of the rim of the wheel but having its edges free, enabling the edges of the
outer rubber cover to be attached to the underside of the edges of the strip of
canvas or other material, whereby the said edges of the outer cover are held
between the edges of the said strip of canvas or other material and the edges of
the rim of the wheel when the tyre is inflated, as set forth.
