PROVISIONAL SPECIFICATION.
Improvements in Packing for Steam Engines and for other
Purposes.
I GEORGE PLATT of Dunham Place Ashton-under-Lyne in the County of Lancaster,
Engine Packing Manufacturer do hereby declare the nature of this invention to be
as follows:-
This invention relates to the manufacture of asbestos and other packing for steam.
engines, pumps and for other purposes, and consists principally in an improved
method of covering the same, the principal object of the invention being to increase
the durability of such packing.
The usual method of covering such packing consists in plaiting or braiding threads.
or strands, of cotton or other fibrous material around the packing in the form of a
tubular covering by means of an ordinary braiding machine.
According to my invention I substitute for the threads or strands of cotton or
other fibre tubular woven or braided banding such for example as is employed for
driving the spindles of spinning and doubling machines, such tubular banding being
either braided hollow, or braided around a core of fibrous material, or a wire of lead,
copper or other metal.
I take a number of these tubular braided bands (either hollow or with a fibrous or
metallic core as above described) and by means of a braiding machine I plait or
braid the same into the form of a tubular cover around the asbestos or other packing
as a core, and by the use of this hollow woven braid or banding (either with or
without a core) instead of the ordinary strands as heretofore employed I produce
a covering which is much stronger and more durable than the ordinary covering as
hitherto made.
The hollow braid or banding may be made of cotton, flax, hemp or other suitable
fibrous material.

COMPLETE SPECIFICATION.
Improvements in Packing for Steam Engines and for other
Purposes.
I GEORGE PLATT of Dunham Place Ashton-under-Lyne in the County of Lancaster
Engine Packing Manufacturer 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:-
This invention relates to the manufacture of asbestos and other packing for steam
engines, pumps, and for other purposes and consists principally in an improved
method of covering the same, the principal object of the invention being to increase
the durability of such packing.
The usual method of covering such packing consists in plaiting or braiding plain
threads or strands of cotton or other fibrous material around the packing in the form
of a tubular covering by means of an ordinary braiding machine."
According to my invention I substitute for the plain threads or strands of cotton or
other fibre tubular woven or braided banding such for example as is employed for
driving the spindles of spinning and doubling machines, such tabular banding being
either braided hollow, or braided around a core of fibrous material or a wire of lead
copper, or other metal.

page_text: I take a number of these tubular braided bands (either hollow or with a fibrous or
metallic core as above described) and by means of a braiding machine plait or
braid the same into the form of a tubular cover around the asbestos or other packing
as a core, and by the use of this hollow woven braid or banding (either with or
without a core) instead' of the ordinary strands as heretofore employed I produce a
covering which is much stronger and more durable than the ordinary covering as
hitherto made.
The hollow braid or banding may be made of cotton, flax, hemp or other suitable
fibrous material and if preferred the said hollow braid or banding may also be used
for the core of the packing.
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 :-
First. The employment of tubular braided bands (either with or without a
core of fibrous material or a wire of lead, copper, or other metal) for forming by
plaiting or braiding an outer tubular covering for asbestos or other. packing sub-
stantially as herein before described.
Secondly. I claim as a new manufacture packing for steam engines and for other
purposes formed with a core of asbestos or other packing combined with an outer
covering formed by plaiting or braiding together tubular braids or handing which
may be either braided hollow or braided round a thin core of fibrous material, or a
wire of lead, copper or other metal substantially as described.
