I, JOSEPH ROBINSON, of 84, Suffolk Road, Ipswich, in the County of Suffolk,
Engineer, do hereby declare the nature of this invention to be as follows:-
-
My invention has for its object to provide improved means for protecting the air
tube of pneumatic tyres against puncture, and such means may be applied to tyres
during their manufacture so as to be integral therewith, or may be made separately
in the form of a puncture proof band or strip to be applied to any existing double
tube tyre.
According to my invention I employ a band or strip of flax, linen, or similar
fabric which I treat or impregnate with a solution of xylonite, celluloid, or the
like, either by applying such solution to the surfaces of the fabric by any suitable
means, or by immersing the fabric in the solution preferably while subjecting the
latter to pressure.
Any suitable number of these prepared strips are arranged between the air tube
and the tread of the tyre, according to the size of the tyre and the kind of vehicle
to which it is to be applied.
I prefer to cement the strips together in pairs, and to superpose or cement together
a number of these pairs of strips, each superposed strip being narrower than that
to which it is secured, and the widest strip being placed adjacent to the air tube.
In making a separate puncture proof band I may provide the prepared strips
with a covering or casing, of sateen, or other fabric.
In some cases I may place strips of solid xylonite or celluloid between the pre-
pared canvas strips immediately after immersion in the solution, so as to obtain a
band of great strength or resistance to penetration.

Improvements in or relating to Pneumatic Tyres.
I, JOSEPH ROBINSON, formerly of 84, Suffolk Road, but now of Tower Ramparts,
Ipswich, in the County of Suffolk, Engineer and Machine Fitter, 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 has for its object to provide for improved means for protecting the air
tube of pneumatic tyres against puncture, and such means may be applied to tyres
during their manufacture so as to be integral therewith, or may be made separately

tube tyre.
According to my invention I employ a band or strip of flax linen or similar
fabric which I treat or impregnate with a solution of xylonite celluloid or the.
like either by applying such solution to the surfaces of the fabric by any suitable
means or by immersing the fabric in the solution preferably while subjecting the
latter to pressure.
Any suitable number of these prepared strips are arranged between the air tubes
and the tread of the tyre, according to the size of the tyre and the kind of vehicle
to which it is to be applied.
Such prepared strips may be employed separately in the form of a detachable
puncture proof band capable of being employed with any existing double tyre tube or
they may be supplied to any tyres during their manufacture so as to be integral
therewith and if desired the tyre lining may also be treated with celluloid but I do
not limit myself to any precise arrangement of band or cover.
The component parts of the band are placed together before the celluloid or other
impregnating substance has become dry or solidified so that the said parts will
adhere. In some cases, however, I may allow the strips to dry separately and then
cement them together with indiarubber solution. I prefer to secure the parts
together by stitches.
The impregnation or treatment of the fabric is effected by applying to each strip
a solution of celluloid, xylonite or the like in acetone by means of a brush or by
immersing each strip in the solution preferably contained in an air-tight bath or
cylinder, in the latter case I may place the solution under pressure so as to cause it
to more thoroughly penetrate the fibres of the fabric.
I prefer to cement the strips together in pairs and to super-pose or cement together
a number of these pairs or strips each superposed strip being narrower than that
to which it is secured, and the widest strip being placed adjacent to the air tube.
In making a separate puncture proof band I may provide the prepared strips
with a covering or casing of sateen or other fabric.
In some cases I may place strips of solid xylonite or celluloid between the pre-
pared canvas strips immediately after immersion in the solution so as to enable a
band of greater strength or resistance to penetration.
And having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The application of a puncture proof band for pneumatic tyres constituted of
flax or similar fabric and in combination with xylonite, celluloid, or similar com-
position, as before described.
2. The application of my puncture proof band as an additional accessory placed
within a pneumatic tyre, or to be built up in the first construction of the tyre, tube
or outer cover, substantially as before described.
