PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, WILLIAM DAVIDSON, of 16 St. Mary's Road, Lower Edmonton, in the
County of Middlesex, Polisher, do hereby declare the nature of this invention to
be as follows:-
My invention relates to pneumatic or air inflated tyres, and it consists, first of a
device to prevent the air tube being punctured, secondly of a device for preventing
friction or wear between the air tube and cover or band placed therein, and thirdly
of an improved valve for inflating the tyre.
The puncture preventing device consists of a band of closely woven wire gauze
adapted to be placed within or incorporated with the cover. The width of the
band is preferably such as will protect the whole of the exposed part of the tyre
outside the rim. In applying this band to covers during their construction it can
be conveniently placed between the reinforcing canvas and the rubber cover.
For application to existing tyres the band may be either cemented or otherwise
fixed to a baud of canvas adapted to be fixed to the inuer face of the cover, or it
may be cemented or otherwise fixed between two strips or bands of canvas adapted
to be placed within the cover between it and the air tube.
To prevent friction or wear between the air tube and the cover or non-puncturable
band therein-if one is used-I coat either or both the air tube and the inner
surface of the cover or band therein with any suitable sticky non-drying solution
which will cause the two parts to adhere to each other and prevent movement with
respect to each other, and will yet allow of their being easily separated the one
from the other. A suitable solution may be made from a mixture of resin and oil.
My improved valve consists of a suitable shaped shank having a recess, against
the shoulder of which is a ball kept up to the said shoulder-on which is located a
leather washer-by a suitable spring.
Dated this 24th day of March 1894.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, WILLIAM DAVIDSON of 16, St. Mary's Road, Lower Edmonton, in the
County of Middlesex, Polisher, 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 air inflated tyres, and it consists first of a
device to prevent the air tube being punctured, and secondly of a means of pre-
venting friction or wear between the air tube and cover or band placed therein.
The puncture preventing device consists of a strip of closely woven wire gauze
mounted on a strip or between two strips of canvas or any other suitable textile
fabric. The width of this compound band is preferably such as will protect the
whole of the exposed part of the tyre outside the rim though it may be of a lesser
width. In applying this compound band to new covers it is either attached to the
[Price 8d 1

page_text: rubber during the process of vulcanization when the canvas or other textile fabric
on which it is mounted may form the reinforcing lining, or it may be placed within
the thickness of the rubber.
For application to existing tyres the compound band may be either fixed to the
inner face of the cover by cement or otherwise in such a manner that the woven
wire gauze lies between the canvas or its equivalent and the inner face of the cover
in case the gauze is mounted on a single strip of textile fabric, or it may be loosely
placed within the cover between it and the air tube.
To prevent friction or wear between the adjacent surfaces of the air tube of the
cover and also of the non-puncturable band-if one is used-they are coated with
a sticky non-drying solution which will cause the respective parts to adhere to each
other and prevent movement with respect to one another and will yet allow of their
being easily separated the one from the other. A suitable solution is made by
adding to boiled oil resin and tallow or their equivalents in the following
proportions :-
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. The improvements in pneumatic tyres substantially as hereinbefore described.
2. The improved puncture-proof band consisting of closely woven wire gauze
with a backing of canvas or other textile fabric, as set forth.
3. The means as hereinbefore described of preventing friction or wear between
the component parts of a pneumatic tyre.
Dated this 7th day of June 1894.
