PROVISIONAL SPECIFICATION.
Improvements in Elastic Tyres for the Wheels of Bicycles, Tricycles,
and other Velocipedes and Wheel Carriages.
We JOHN EDWARD RICKARDS of Brookdale, St. Mary's Road Stechford in
the County of Worcester Manufacturer and WILLIAM PRIEST of Sheepcote
Street Birmingham in the County of Warwick Manufacturer do hereby declare
the nature of this invention to be as follows:-
The said invention consists of the methods hereinafter described of constructing
the said tyres, whereby a light and elastic tyre is produced very efficient. in action,
economical in construction and less liable to injury in use than elastic tyres as
ordinarily constructed.
In constructing a tyre according to the said invention we proceed as follows;-
We take a tube of vulcanized india rubber or other elastic material and we fill or
stuff the said tube with cotton fibre either in the form of cotton wool or wadding or
flock, the said cotton wool being introduced either by forcing into the tube a series
of detached plugs or pledgets or cores of cotton wool, or by twisting cotton
wadding into a rope like figure and inserting the same into the india rubber tube or
by inserting and ramming therein cotton fibre wadding or flock. The tube having
been filled with cotton fibre in any convenient way its ends are joined and the tyre
formed may be fixed to the metallic or other rim of the wheel in any convenient
manner.
Or we make the tyre of a series of concentric india rubber tubes or other elastic
material of such different diameters that layers of cotton may be introduced
between the said tubes. Or we take sheets or layers of india rubber and wadding
and placing them on a flat surface alternating with each other edge to edge, roll
them up into the form of a cylinder and insert the cylinder thus made into the
india rubber tube or covering constituting the outer portion of the tyre. A tyre
made in the way last described nearly resembles the tyre made with concentric
tubes with layers of wadding between them.
Or the tyre may be made by first filling an inner case of vulcanized india rubber
or other elastic material with cotton wool and passing the filled case into an outer
case of vulcanized india rubber, composition or other elastic material.
Tyres made according to this invention are very elastic. They are not so likely
to be punctured when used on a rough road as inflated tyres are and if punctured
they do not collapse and become immediately disabled as inflated tyres do.

We JOHN EDWARD RICKARDS of Brookdale, St. Mary's Road Stechford in
the County of Worcester Manufacturer and WILLIAM PRIEST of Sheepcote
Street Birmingham in the County of Warwick, Manufacturer do hereby declare
the nature of our said invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The said invention consists of the methods described of constructing the said

page_text: tyres whereby a light and elastic tyre is produced very efficient in action,
economical in construction and less liable to injury in use than elastic tyres as
ordinarily constructed.
In constructing a tyre according to the said invention we proceed as follows:-
We take a tube of vulcanized india rubber or other elastic material and we fill or
stuff the said tube with cotton fibre either in the form of cotton wool or wadding
or flock, the said cotton wool being introduced either by forcing into a tube a series
of detached plugs or pledgets or cores of cotton-wool or by twisting cotton wadding
into a rope like figure and inserting the same into the india rubber tube or by
inserting and ramming therein cotton fibre, wadding or flock. The tube having
been filled with cotton fibre in any convenient way its ends are joined and the tyre
formed may be fixed to the metallic or other rim of the wheel in any convenient
manner.
Or we make the tyre of a series of concentric india rubber tubes or other elastic
material of such different diameters that layers of cotton may be introduced
between the said tubes. Or we take sheets or layers of india rubber and wadding
and placing them on a flat surface alternating with each other edge to edge, roll
them up into the form of a cylinder and insert the cylinder thus made into the
india rubber tube or covering constituting the outer portion of the tyre. A tyre
made in the way last described nearly resembles the tyre made with concentric
tubes with layers of wadding between them.
Or the tyre may be made by first filling an inner case of vulcanized india rubber
or other elastic material with cotton wool and passing the filled case into an outer
case of vulcanized india rubber composition or other elastic material. Tyres made
according to this invention are very elastic. They are not so likely to be punctured
when used on a rough road as inflated tyres are if punctured they do not collapse
and become immediately disabled as inflated tyres do.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a sheet of drawings upon which we have
illustrated the nature of our said improvements.
Figure 1 is a section through one form of our tyre.
Figure 2 is a similar section but shewing a modification.
Figure 3 is also a section shewing another modification.
In carrying our invention into effect we form our tyre of a tube of vulcanized
india rubber or other suitable elastic material A which we fill or stuff with cotton
wool wadding or flock B which may be inserted either by forcing into the tube a
series of detached plugs of such material or fibre or by forming or rolling the
cotton wool wadding or flock into a rope like form of any consistency after which
it is drawn into the tube or the core may be first formed or moulded out of cotton
wool wadding or flock fibre in lengths or one whole piece and the solution of rubber
formed around same. In place of the rubber we may form a cover of skin or other
* suitable material.
We may form our tyre of a series of tubes one within the other such as E F
with cotton wool wadding or flock inside the inner one as shewn by Figure 2 while
the inner tube E may be formed of either rubber silk skin or canvas the outer tube
being vulcanized rubber.
We may form our tyre as shewn by Figure 3 in which the inner case H which is
formed of vulcanized india rubber silk, skin or canvas is filled with cotton wool
wadding or flock and after being covered with a similar coating of cotton wool
wadding or flock is inserted A¹ within or covered by the outer covering of rubber K
or a similar tyre may be formed by taking sheets or layers of india rubber and
wadding and rolling them into a tyre similar to that shewn by the inner part of
Figure 3 the cylinder thus formed being inserted in the outer covering K. The
outer rubber tube may be thickened on the tread or may be of the same thickness
throughout.

page_text: Having therefor now particularly described and ascertained the nature of our
said invention and in what manner the same is to be performed what we
claim is
1st. The improvements in elastic tyres for the wheels of bicycles tricycles and
other velocipedes and wheel carriages substantially as herein set forth and shewn
upon the accompanying drawing.
2nd. An elastic tyre consisting of an outer casing of vulcanized rubber
packed with cotton wool wadding or flock substantially as herein set forth and
shewn.
3rd. An elastic tyre formed into concentric and alternate rings of rubber skin or
canvas and cotton wool wadding or flock substantially as herein described and
shewn upon the accompanying drawings.
4th. In the manufacture of an elastic tyre the mode of means for forming the
same substantially as herein set forth and shewn upon the accompanying drawing.
Dated this 21st day of August 1893.
