PROVISIONAL SPECIFICATION.
Improvements in Tyres for Wheels.
I SAMUEL HAMILTON Junr. Managing Inn Keeper of the Commercial Hotel
Hebburn Quay near Newcastle on Tyne do hereby declare the nature of this inven-
tion to be as follows:-
A new and improved form of tyre for light wheels such as are usually employed
in the construction of bicycles, tricycles infants perambulators invalid carriages and
the like. Such tyres are usually made of india rubber and are either solid inflated
or built up as the case may be.
My invention consists of the employment of cork for this purpose. I employ the
cork either simply by itself or as a core or lining to some suitable hollow tube
made of india rubber gutta percha, canvas, leather, or cloth or a combination of
these materials. Or as an outer covering or wearing face to the description of tyres
known as <<
pneumatic." The method of application in the case of the solid cork
tyre, is, to cut strips of cork into cylindrical pieces preferably of a radius corre-
sponding to the size of the wheel used. The strips are then cemented or otherwise
secured to the steel or iron rim of the wheel.
In the case where it is desired to use the cork as a core or lining, the tube having
been first prepared, strips of cork of convenient length and diameter are forced in,
either with or without the addition of cement or glue, and then the whole "sausage
so prepared is cemented or otherwise fixed to the rim of the wheel.
<
"
In the case where it is desired to use the cork as a means of protection and
additional elasticity to the tyres known as pneumatic," then, strips of cork are
prepared having a sectional shape somewhat approximating to a segment of a tube
and corresponding in radius to the tyre they are to be fixed on, these strips are
then cemented or otherwise fixed on to the outer surface of the pneumatic tyre and
will therefore come in direct contact with the ground.
I claim the invention and application of cork (either in its ordinary commercial
form or compressed) to the purpose of making tyres for light wheels for bicycles,
tricycles infants perambulators invalid carriages and the like.
And I claim the invention of its use either by itself or in conjunction with and
as a core or lining to a case composed of india rubber gutta percha leather, canvas
cloth or wire gauze or a combination of these materials.
I also claim the invention and application of cork to pneumatic tyres in the
manner above described in which it will be seen that it is applied in such a manner
as to become the wearing surface of the whole wheel at the point of contact with
the ground.

Improvements in Tyres for Wheels.
I, SAMUEL HAMILTON Junr. Managing Innkeeper of the Commercial Hotel,
Hebburn Quay near Newcastle on Tyne do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
5 described and ascertained in and by the following statement:-
This is a new and improved form of tyre for light wheels such as are usually
D
דו.

page_text: employed in the construction of bicycles, tricycles infants perambulators invalid
carriages and the like. Such tyres are usually made of india rubber and are either
solid, hollow, inflated or built up as the case may be.
My invention consists of the employment of cork for this purpose. I employ the
cork simply by itself, or as a core or lining to some suitable hollow tube made of
india rubber gutta percha, canvas, leather or cloth or wire gauze or a combination
of these materials. Or as an outer covering or wearing face to the description of
tyres known as pneumatic.
The method of application in the case of the solid (or perforated) tyre is, to cut
strips of cork into cylindrical pieces preferably of a radius corresponding to the
size of wheel used. These strips are then cemented or otherwise fixed to the steel
or iron rim of the wheel.
In the case where it is desired to use the cork as a core or lining, the tube
having been first prepared, strips of cork of convenient lengths and diameter are
forced in either with or without the addition of a cement or glue and then the
whole "sausage
so prepared is cemented or otherwise fixed to the rim of the
wheel.
"
In the case where it is desired to use the cork as a means of protection and
additional elasticity to the tyres known as "pneumatic," then strips of cork are
prepared having a sectional shape somewhat approximating to a segment of a tube
and corresponding in radius to the tyre they are to be fixed on. These strips are
then cemented or otherwise fixed on to the outer surface of the pneumatic tyre and
will therefore come in direct contact with the ground.
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. I claim the invention and application of cork (either in its ordinary com-
mercial state or compressed) to the purposes of making tyres for light wheels for
bicycles, tricycles infants perambulators, invalid carriages and the like. I claim
its use either as a solid tyre of cork or as having one or more radial perforations,
for the purpose of lightening it and in that case the tyre would be a hollow tube of
cork and if with only one perforation would resemble the tyres known as cushion
tyres.
2nd. I claim the invention of the use of cork in conjunction with and as a core or
lining to a case composed of india rubber, leather, canvas, cloth or wire gauze or a
combination of these materials.
3rd. I claim the invention and application of cork to pneumatic tyres in the
manner above described, in which it will be seen that it is applied in such a manner
as to become the wearing surface of the whole wheel, at the point of contact with
the ground.
