An Unpuncturable Lining for Pneumatic Tyres.
FREDERICK CHARLES TIPLER, 48, Brooklyn Street, Crewe, Analytical Chemist,
THOMAS ANDREW GLADDEN, 82, Gresty Road, Crewe, Jeweller, do hereby declare
the nature of this invention to be as follows:-
The said lining to consist of a fabric, (specially woven or otherwise) rendered
unpuncturable by being soaked and afterwards coated in a suitable manner with a
solution of sodium silicate or potassium silicate or silicates of the alkaline earthy
metals or silicic acid.
The fabric after the above treatment to be dried or partially dried at a suitable
temperature. We do not confine ourselves however to the above substances, and
further these may be used mixed with other suitable material. The fabric to be
then coated with india-rubber solution or rendered water-proof by any other suit-
able material or process. In the case of a single tube tyre the lining to be cemented
to it. But where the tyre consists of an outer cover and inner air tube, the lining
may be either cemented to the outer cover, or inserted between the two.

THOMAS A. GLADDEN,
An Unpuncturable Lining for Pneumatic Tyres.
We, FREDERICK CHARLES TIPLER, of 48, Brooklyn Street, Crewe, Analytical
Chemist, and THOMAS ANDREW GLADDEN, of 82, Gresty Road, Crewe, Jeweller, 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:-
:-
Our invention has for its object the protection of a pneumatic tyre from puncture
by means of a lining, or part lining consisting of one or more longitudinal strips
or layers of a treated fabric, which, while offering protection to the air tube or
chamber, detracts but little from the resiliency of the tyre.
The fabric, which may be of cotton or other suitable absorbent material, (specially
woven or otherwise) is soaked in, coated or otherwise treated with, a solution of
a soluble silicate, or silicic acid (and if desirable afterwards treated with a solution
of a soluble salt of barium, strontium, calcium, or magnesium, the object being to
form their respective silicates), and afterwards dried, and rolled.

page_text: Having thus briefly described the preparation of the lining, we now proceed to
a detailed description:-
A convenient length and width of fabric is taken, and slowly drawn through an
aqueous solution of a silicate, (preferably potassium silicate) and afterwards slowly
dried at, from 100° to 120° C. This operation is repeated two or three times,
according to the thickness of the fabric, and the strength of the solution. The
treated fabric is next passed several times through metal rollers, to render it
pliable, and afterwards made water-proof, when necessary, by being coated with
rubber solution, or other suitable water-proofing material.
The application of the above lining may be as follows:-Where the tyre consists
of an air tube, and a separate outer cover, the puncture resisting lining may be
inserted in the tread of the canvas or fabric lining of the outer cover, or it may be
used in the form of a band to be inserted between the air tube and outer cover
of the tyre, or the canvas lining of the outer cover may itself be treated in the
manner already described. In the case of a single tube, or tubeless tyre, the
ture resisting lining may be inserted in the tread of the canvas or fabric lining of
pune-
the tyre, or the canvas lining may itself be treated in the manner already described.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:-
1. A puncture resisting lining, or part lining for pneumatic tyres, consisting of
fabric, (canvas, or other suitable absorbent material) treated with potassium silicate,
sodium silicate, or the like, and afterwards rendered pliable by being rolled.
