PROVISIONAL SPECIFICATION.
Improvements in Velocipede Wheels.
I, JOHN HARRINGTON of 14 West Kensington Gardens, in the County of
Middlesex, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in that class of velocipede wheel
which is provided with a cushioned or pneumatic tyre, and relates to means
whereby such wheels can be readily constructed, the india rubber tyre securely
held in position, and the said tyre secured against being cut by the edges of the
felloe, whilst velocipede makers are enabled to apply the tyres to wheels on their
own premises, and thereby obviate the delays which are now occasioned with
respect to pneumatic tyres by the necessity for sending the wheels away to have
such tyres applied thereto.
According to my invention, I construct the wheel with a hollow felloe, having
preferably a section of about three quarters of a circle, and having the edges
curved outwards or formed with comparatively thick curved ribs. Or such hollow
felloe may be of elliptical or other curved section, or it may be of square or of other
angular or of compound section. The hollow rubber tyre is made of form to fit the
section of the felloe and is provided with a thickened or extended wearing
surface, which may be of the same or of a different quality of rubber to that of the
non-wearing part thereof; the respective dimensions or proportions of the tyre
and felloe being such that on the compression of the tyre to its fullest extent,
the edges of the felloe shall not come into contact with the ground, whilst the
hollow portion of the tyre is completely supported by the felloe all around the
exterior thereof, except at that part adjoining its running surface.
I also propose in some cases to form the wearing portion of the tyre separate
from the tubular part, in which case I form the felloe with cheeks within which
the wearing portion of the tyre is located and from which it projects sufficiently
far to prevent the edges of the felloe from coming into contact with the ground
on the compression of the tyre. I also in order to afford a secure holding to
the wearing portion of the tyre form it with flaps to be tucked in between the
cushion and shield. By the above means the wearing portion of the tyre can be
renewed without interfering with the cushion or tubular part thereof.
In order to strengthen the wheel I attach the spokes to the felloe alternately on
each side of the centre line thereof, thereby greatly stiffening the same.

COMPLETE SPECIFICATION.
Improvements in Velocipede Wheels.
1, JOHN HARRINGTON, of 14 West Kensington Gardens, in the County of
Middlesex, Manufacturer, 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 :-
The invention has for its object improvements in that class of wheel which is

page_text: provided with a cushioned or pneumatic tyre, and relates to means whereby such
wheels can be readily constructed, the india rubber tyre securely held in position,
and the said tyre secured against being cut by the edges of the felloe, whilst
velocipede makers and other users of such, wheels are enabled to apply the tyres to
wheels on their own premises and thereby obviate the delays which are now
occasioned with respect to pneumatic tyres by the necessity for sending the wheels
away to have such tyres applied thereto.
The accompanying drawing represents a cross section of the felloe and tyre. of a
wheel constructed according to my invention.
According to my invention I construct the wheel with a channelled felloe, a
having preferably a section of about three quarters of a circle, which may have the
edges curved outwards or formed with comparatively thick curved ribs to prevent
the cutting of the tyre, but, as shown in the drawing, I prefer to form the felloe a
with cheeks a¹.
a,
If desired the felloe a may be of elliptical or other curved section, or it may be
of square or of other angular or of compound section. The hollow or inflated
portion of the rubber tyre is made of form approximately to fit the section of the
felloe
and it is provided with a thickened or extended wearing surface b', which
may be of the same or of a different quality of rubber to that of the non-wearing
part thereof, the respective dimensions or proportions of the tyre 6 6¹ and
felloe a a¹ being such that on the compression of the tyre to its fullest extent, the
edges of the felloe shall not come into contact with the ground, whilst the hollow
or inflated portion 6 of the tyre is completely enclosed by the felloe all around
the exterior thereof, except at that part adjoining its running surface.
The wearing portion of the tyre I preferably form of a harder rubber:
compound than that employed for the hollow or inflated portion thereof, and
I preferably cement such parts together and, in some cases, in order to afford
a more secure holding, I form the said wearing portion 61 of the tyre with
flaps 2, shown by dotted lines, which are cemented to the hollow or inflated
part b. If desired the wearing part 6' of the tyre may be separate from the tubular
or inflated part 6 and be simply sprung into position, but in either case it can be
readily renewed without interfering with the cushion or tubular part thereof.
The wearing portion of the tyre is located between the cheeks a¹ and projects
sufficiently far therefrom to prevent the edges of the felloe from coming into contact
with the ground on the compression of the tyre.
The hollow portion b of the tyre may be of the character known as cushioned,
or it may be formed of an air proof rubber tube protected with a covering of
webbing or canvas.
For the purpose of strengthening and stiffening the wheel, the spokes c may be
attached to the felloe alternately on each side of the centre line thereof, as shown.
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 :-
1. In velocipede wheels, the combination of a felloe completely enclosing the
hollow or inflated portion of the tyre, except at that part to which the tyre wearing
surface is applied, and a tyre composed of a hollow or inflated portion, located
within such felloe, and an exterior wearing part applied thereto, substantially as
herein shown and described.
f
2. In velocipede. wheels, the combination of a felloe completely enclosing and
protecting the hollow or inflated portion of the tyre, except at that part to which
the tyre wearing surface is applied, projecting cheeks attached to such felloe, a
hollow or inflated tyre located within the felloe and a tyre wearing surface located
between said cheeks and resting upon; the hollow or inflated portion, substantially, as
herein shown and described.
3. In velocipede wheels, a tyre consisting of a hollow or inflated portion located
•

page_text: within the felloe and a projecting wearing part either attached to or loose from
such hollow or inflated portion, substantially as herein shown and described.
