Improvements in the Manufacture of Jackets or Covers for
Pneumatic Tyres.
I, HERMANN PAULSEN, London Manager of the Harburg & Vienna India
Rubber Company, of Tower Chambers, Moorgate Street, in the City of London,
Manufacturers do hereby deolare the nature of this invention (a communication to
me by Carl Maret, Managing Director of the said Company at Harburg-on-the-
Elbe, in the Gorman Empire) to be as follows:-
This. invention relates to the manufacture of jackets or covers. for..
r. .pneumatic
tyres the object of the invention being. to protect such covers.or.jackets. from.
puncture without at the same time. destroying the natural elasticity.of.the.indin-
rubber as is now generally, the case when such jackets or covers are protected by:
woven facings or insertions..
According to the said invention I make use of a braided material instead of
woven material as heretofore, the said braided material being applied in such
a manner that it will permit of the longitudinal expansion of the jacket or
cover.
The braided material may be composed of cotton, silk, hemp, flax or other
suitable fabric and may be inserted in the body of the india-rubber or applied upon
the face of the same.

Improvements in the Manufacture of Jackets or Covers for
Pneumatic Tyres.
I, HERMANN PAULSEN, London Manager of the Harburg & Vienna India-
rubber Company, of Tower Chambers, Moorgate Street, in the City of Loudon,
Manufacturers, do hereby declare the nature of this invention (a communication
to me by Carl Maret, Managing Director of the said Company at Harburg-on-
the-Elbe, in the German Empire) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the manufacture of jackets or covers for pneumatic
tyres, the object of the invention being to protect and strengthen such covers
or jackets without at the same time destroying the natural elasticity of the
india-rubber, as is now generally the case when such jackets or covers are protected
by woven facings or insertions.
According to the said invention I make use of a braided or plaited material
instead of woven material as heretofore, the said braided material being applied
in such a manner that it will permit of the longitudinal expansion of the jacket
or cover.

page_text: This invention will he fully understood by reference to the accompanying
drawing, in which :-
Figure 1 is a plau view of a portion of a tyre jacket or cover laid out flat and
baving the braided or plaited fabric applied to the surface thereof; and,
Figure 2 is a transverse section of the same:
In these figures a, a indicate the threads of the braided or plaited fabric, the
latter being so laid upon the india-rubber that the said threads are at angles of
about 45 degrees to the lateral edges of the india-rubber, whereby the longitudinal
expansion of the fabric is provided for.
The braided or plaited fabric may be composed of cotton, silk, hemp, flax or
other suitable material and instead of being applied upon the surface of the india-
rubber may be inserted in the body of the same.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I'
claim is :-
1. The improvement in the manufacture of jackets or covers for pneumatic tyres
consisting in applying to or incorporating with the india-rubber a braided or plaited
material substantially as, and for the purposes, described.
.
2. The manufacture and use of jackets or covers for pneumatic tyres, substantially
as bereinbefore described and illustrated in the accompanying drawing.
