Improvements in Pneumatic Tyres and Rims for the Wheels of
Cycles and other Light Road Vehicles.
I, JOHN NEWHOUSE, Cotton Weaver, 9, Laithe Street, Knott's Lane, Colne,
Lancashire, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in pneumatic tyres & rims for the wheels
of cycles & other light road vehicles.
Hitherto wired on pneumatic tyres have been attached to the rim by means of
wires connected with the edges of the outer cover, or tread; thus making them
difficult to detach for repairs. According to my invention pneumatic tyres are
attached to rim by means of a combination of wires & thickened, or enlarged rubber
edges; the wires being connected with the inner inflating tyre, or air tube, & the
thickened, or enlarged, rubber edges to the outer protecting cover, or tread; thus
making detachment for repairs more easy than with the ordinary wired on tyre.
This tyre consists of an inner inflating tyre or air tube, in combination with an
outer protecting cover, or tread. The outer protecting cover consists of vulcanised
elastic india rubber, or india rubber & canvas, or the like; arch shaped in trans-
verse section, as heretofore; & with thickened, or enlarged, elastic rubber edges,
which fit into the grooved channel of the rim.
The inner inflating tyre, or air tube, consists of india rubber, lined, or backed with
canvas, or the like, & with wires, cords, or other suitable inextensible materials,
stitched into the edges of the canvas, or otherwise suitably connected with the edges,
or sides of the said inflating tyre, or air tube, so that when the tyre is inflated the
wired, or banded, edges of the air tube may rest upon the thickened, or enlarged,
edges of the outer cover, or tread; locking it fast to the rim.
I prefer to use a rim (in combination with my improved tyre) shallower in the
" rin;
grooved channel, below the shoulders, than the ordinary "Dunlop Welch
because the wired edges of the inner tyre, or air tube, do not rest upon the shoulders
of the rim, but upon the thickened, or enlarged, edges of the outer cover, about an of
an inch above. But I do not confine myself to this form of rim. I may use a rim
with a flat base or channel. My improved tyre may also be attached to the
Dunlop Westwood" rim, or to the "Dunlop Welch "rim; preferably "James's'
pattern, with divided spokes.
وو
In some cases the wires, or cords, may be stitched into (or otherwise connected
with) the edges of a narrow strip of canvas, which is cemented, or vulcanised, to the
base, or inner circumference of the air tube. In all cases one edge of the outer
cover may be permanently cemented to the rim; & one of the wires may also be
secured to the rim.

I, JOHN NEWHOUSE, formerly of 9, Laithe Street, but now of 6, Essex Street
Colne, in the County of Lancaster, Cotton Weaver, 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:-
-
This invention relates to improvements in pneumatic tyres and rims for the
wheels of cycles, and other light road vehicles.
Hitherto wired on pneumatic tyres have been attached to the rim by means of
wires connected with the edges of the outer protecting cover or tread. This makes
them difficult to detach for repairs.
According to my invention pneumatic tyres are attached to the rim by means of
a combination of wires and thickened or enlarged elastic rubber edges. The wires
. are attached to the inner inflated tyre or air tube, and the thickened rubber edges
are attached to, or formed integrally with, the outer protecting cover or tread.
This method of construction enables the tyre to be detached or replaced with greater
facility than heretofore.
"
The improved tyre consists of an inner inflatable tyre, or air tube, in combination
with an outer protecting cover or tread. The latter consists of vulcanised elastic
india-rubber, or india-rubber and canvas or the like, arch shaped in section as here-
tofore, and provided along each of its edges with a thickened elastic beading or
ridge which engages a corresponding groove or recess in the rim. The inner
inflatable tyre, or air tube, is formed of india-rubber, lined or backed with canvas or
the like, and provided with wires, cords or other inextensible materials stitched into
the edges of the canvas, or otherwise suitably connected with the sides of the said
air tube. Therefore when the latter is inflated the wired edges jam portions of the
outer cover against the sides of the rim. The rim is specially shaped for this
purpose, and is hereinafter fully described.
In order that the invention may be clearly understood I append drawings in
which:
Fig. 1 is a transverse section of a tyre and rim constructed according to my
invention.
Fig. 2 is a section of the rim and outer cover only.
Fig. 3 is a section of an inflatable inextensible air tube detached.
Fig. 4 is a section of a tyre with a modified form of rim.
Figs. 5 and 6, are sections of tyres as attached to Westwood and Dunlop-Welch
rims.
A is the outer cover or tread arch shaped in section, and provided along each of
its edges with a thickened bearing or ridge A¹ of any desired section, but preferably
of the sections shewn in Figs. 1 and 4. B is an internal lining to the outer cover A
made of canvas or other suitable material. C is the inflatable air tube, preferably
of rubber, and this is attached to an annular external layer c of canvas or the like
which embraces the greater portion of the section of the tube C, and may be vulca-
nised or otherwise attached thereto by cement or the like. Each of the edges of
the layer is provided with a wire D stitched in a fold, or otherwise fixed in
position. When the air tube as shewn in Fig. 3 is used the outer cover A may
consist of india-rubber only, because the air tube being backed with canvas is
inextensible, but I prefer to make the outer cover of india-rubber and cloth or
like fabric in all cases.
E and E¹ are different forms of wheel rims which as shewn are of special section
i.e. they are formed with deep sides, and flat or dished shallow channels e.

page_text: To attach the tire to the rim, the inner tube is first put on; the wires on one side
being pressed into the channel of the rim until the remainder is slipped over the
edge of the rim. The thickened edges of the outer cover are then slipped under the
wires into the channel of the rim, and the tyre inflated, when the wires are forced
to the sides of the rim and take up their position upon the thickened edges, of the
outer cover, as shewn in Figs. 1 and 5, thus firmly holding the tyre in position.
The cloth backing or lining c may in some cases be disposed inside the air tube.
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. A tyre for the wheels of bicycles and other light road vehicles, consisting
essentially of an outer cover or tread of india-rubber, or india-rubber and canvas,
the edges of said outer cover being beaded or ridged to engage shallow channels in
the rim, and an inner inflatable tube, to the sides of which wires are connected,
said wires being embedded in an exterior canvas casing to the inner tube, whereby
the inflation of the latter causes the wires to jam the edges of the outer cover against
the sides of the rim, substantially as shewn and described.
2. In a tyre for the wheels of bicycles and other vehicles, the combination of the
inflatable rubber tube C, the exterior canvas or other casing c, the wires D
embedded in the edges thereof, the outer cover or tread A, and the rims E, sub-
stantially as shewn and described.
3. In a tyre for the wheels of bicycles and other vehicles, the combination of the
inflatable rubber tube C, the exterior canvas or other casing c, the wires D,
embedded in the edges thereof, both being cemented or otherwise connected to the
tube C, the outer cover or tread A, the beaded or thickened edges A¹ thereof, and
the rim E, substantially as shewn and described.
4. In a tyre for the wheels of bicycles and other vehicles, the combination of the
inflatable rubber tube C, the exterior canvas or other casing c the wires D embedded
in the edges thereof, the outer cover or tread A, the beaded or thickened edges A'
thereof, the rims E or E', and the channels e formed therein, substantially as shewn
and described.
