I CHARLES EDWARD HOLDEN of 118 Balfour Street Oldham in the County of
Lancaster Cotton Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to Pneumatic Tyres for Cycles and other vehicles,
its object being to provide a more simple & efficient method of rendering inflated
Tyres non-puncturable than hitherto used. It may either be used as an adaptation
to existing types of Pneumatic Tyres or suitably arranged so as to form a new non-
puncturable pneumatic tyre. To attain this object I insert between the air tube or
air chamber and the outer cover a layer or layers of very fine Bleached Cotton
Raisings or fibres which have been produced by the method known as raising from
Cotton Cloth of the kind known as Swansdown or other similar cloths, such raisings
are much finer and thinner of fibre than the natural or raw cotton fibres and by
bleaching are rendered more tenacious by reason of the natural oil being extracted &
also thereby considerably decreasing the weight.
These raisings are then by the aid of Suitable machinery made in the
form of a sliver or wadding of suitable size & weight & used in the manner above
described.
I am quite aware that cotton as an admixture with other materials has been used
before for the purpose of rendering Pneumatic Tyres puncture proof but it will be
understood that the principal feature of my invention consists in the particular use of
cotton fibres of special properties as herein before described and which differ essentially
from the previously known method of using cotton for this purpose.

Improvements in Pneumatic Tyres for Cycles and other Vehicles.
I, CHARLES EDWARD HOLDEN of 118 Balfour Street, Oldham in the County of
Lancaster Cotton 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:-
My invention relates to pneumatic or inflated tyres that are applied to the wheels
of cycles, motor cars, and other vehicles. The object of my invention is to provide a

page_text: simple and efficient means for rendering inflated tyres puncture proof or to neutralize
the effects of puncture, and may be applied either to existing forms of tyres or may
be employed as a new construction of pneumatic tyre that is unpuncturable. I attain
this object by inserting between the air tube or chamber and the outer cover, either
separately or so as to form an integral part of either the air tube or the cover of the
air tube, a layer or layers of very fine bleached cotton fibres which have been produced
from cotton cloths such as swansdown or other similar cloths during the process of
finishing either by a Moser raising machine or other like mechanical device and which
are termed raisings, or a layer or layers of other bleached fibrous raisings which have
been produced in like manner from bleached china grass or ramie, jute, hemp, silk,
and the like which I form by means of suitable machinery into a sliver or wadding of
suitable size and weight. The aforesaid bleached raisings are much finer in thinness
of fibre than the natural or raw fibres, as by the process of bleaching they are rendered
more tenaceous in consequence of the natural oil being extracted and the weight
thereby considered reduced.
In the application of my invention I place a layer or layers of the hereinbefore
described sliver or wadding between linings of canvas on the inner side of the cover or
envelope during the construction of said cover or envelope, or if a single air tube or
chamber is employed without an outer cover, my invention is applied in like manner
to the circunferential portion of said air tube or chamber which forms the tread of
the tyre.
In applying my invention to existing tyres which are constructed with an air tube
contained within an envelope or cover I form a band of the aforesaid bleached cotton
or other fibrous raisings either with or without a lining of canvas or like material and
place said band circumferentially between the air tube and the cover.
By these means the air chamber in a pneumatic tyre is rendered impenetrable or if
punctured the effects of the puncture are neutralized by the absorbent nature of the
bleached material hereinbefore described, which will attract moisture that may be
injected through the valve and effectually close any puncture that may be produced
by a sharp or pointed substance.
I am aware that cotton as an admixture with other materials has been employed
prior to the date of this application, for the purpose of rendering pneumatic tyres
puncture proof and I therefore do not claim the use of cotton except in the particular
manner herein set forth but,
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. In pneumatic or inflated tyres the use of bleached cotton raisings which have
been produced by the method known as raising from cotton cloth such as swansdown
or other similar cloths or other bleached fibrous raisings that have been produced in like
manner from china grass or ramie, jute, hemp, silk and the like, which is formed into
a sliver or wadding of suitable size and weight and employed in combination with
either the air tube or the outer cover enclosing the air tube so as to form an integral
part of said air tube or said outer cover for the purpose and in the manner substantially
as herein before described.
2nd. In pneumatic or inflated tyres the use of bleached cotton raisings which have
been produced by the method known as raising from cotton cloth such as swansdown
or other similar cloths or other bleached fibrous misings that have been produced in
like manner from china grass or ramie, jute, hemp silk and the like, in combination
with a lining of canvas or other suitable material formed in a band and placed
circumferentially between the air tube and the cover of the air tube for the purpose
and substantially as herein before described.
3rd. In pneumatic or inflated tyres the use of bleached cotton raisings which have
been produced by the method known as raising from cotton cloth such as swansdown
or other similar cloths, or other bleached fibrous raisings that have been produced in
like manner from China grass or ramie, jute, hemp, silk and the like, which is formed

page_text: into a sliver or wadding of suitable size and weight and employed either separately or
so as to form an integral part of either the air tube or the cover of the air tube, for
the purpose and in the manner substantially as herein before described.
