PROVISIONAL SPECIFICATION.
Improvements in Packing for Steam and other Glands and Heat
Joints.
I, ALFRED MORGAN JAMES of 1 New Dock Street, Newport, Monmouthshire,
Engineer and Merchant, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to provide an inexpensive, elastic, and
durable packing for the glands of steam and other engines, and the invention
consists in the combination of canvas and rubber, with a fibre such as flax, hemp,
or jute.
These two agents have been used separately for the purpose referred to but I
intend using them in combination as now described.
The centre and the larger part of the packing is composed of a yarn spun out of
Italian flax or similar fibre (which may be lubricated or otherwise) and around this
is tightly wrapped the exterior consisting of canvas coated with rubber; the use of
the internal fibre being to act as a soft and elastic cushion, and to make the
packing more flexible, while the exterior presents an even and durable surface to
the moving parts.
Dated this 19th day of November 1890.

COMPLETE SPECIFICATION.
Improvements in Packing for Steam and other Glands and Heat
Joints.
1, ALFRED MORGAN JAMES of 1 New Dock Street, Newport, Monmouthshire,
Engineer and Merchant, 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 :-
The object of the present invention is to provide an inexpensive, elastic and
durable packing for the glands of steam and other engines, and the invention
consists in the combination of an interior plaited or twisted yarn of flax, hemp,
jute cotton or asbestos, with an exterior of woven cloth or canvas, made of the same
or different fibre and proofed with india-rubber solution or otherwise.
The centre or core of the packing is composed of a tightly twisted yarn spun out
of a suitable fibre, and around this is tightly wrapped the exterior consisting of
woven cloth or canvas, the use of the internal yarn or rope being to act as a soft
and elastic cushion, and to make the packing more flexible and compressible, while
the exterior presents an even and durable surface to the moving parts of the
engine.
By preference I form the interior core of yarn spun out of the aloe fibre, a specially
suitable white hemp, twisted tightly, and steeped in an adhesive solution, and
around this core is closely wrapped a few layers of cotton duck, coated with india-
rubber but I can also employ the other materials before described, the size of the
yarn, and the number of coils of cloth, being dependent upon the sectional diameter
of the packing required.

page_text: 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. In a packing for the glands of steam engines and like purposes the combination
of an interior plaited or twisted yarn of any suitable fibrous material, with an
exterior of woven cloth or canvas made of the same or different fibre which may be
proofed with india-rubber solution or not as preferred, as herein described and
explained.
2. In a packing for the glands of steam engines and like purposes, the special
combination of an interior yarn of aloe fibre with an exterior covering of cotton
duck or canvas, proofed with india-rubber as herein described and explained.
