Improvements in Packing for Stuffing Boxes of Steam Engines,
Pumps, and other Mechanical Appliances, with its Mode of
Manufacture.
JAMES BURAL BURRELI. of 47 Eldon Road, Cardiff in the County of
Glamorgan Marine Engineer do hereby declare the nature of this invention to be
as follows:-
An improved packing and its mode of manufacture. Its object is durability in
keeping a stuffing box perfectly tight with less friction, and to withstand a high
degree of pressure. It is made of a fibrous material combined with a lubricating
material, such as plumbago, soapstone, or mica. The fibrous material such as
asbestos-hemp, flax, jute, or cotton, either separate or two or more combined. The
fibrous material is spun into yarn woven or plaited into tape or ribbon to size
required. As it is being spun woven or plaited the lubricating material such as
plumbago and soapstone is added either dry or mixed with water or oil, or the
lubricating material such as soapstone and plumbago can be added after it is made
into tape or ribbon. The tape or ribbon is then placed in several layers to
thickness required, then sewn together in lengths. It is then wetted and pressed in
suitable machine if so required to solidify it in any shape. It can then be soaked in
oil or grease to suit special purposes; after the fibrous and lubricating material is
made into tape or ribbon either before or after it is sewn together, and before it is
soaked in oil, it can be treated or soaked in a solution of potash and rosin, and
afterwards treated or soaked in a solution of alum, it is then dried. This process is
to make it damp proof.

Improvements in Packing for Stuffing Boxes of Steam Engines,

Manufacture.
JAMES BURAL BURRELL 47 Eldon Road Cardiff County of Glamorgan Marine
Engineer, do hereby declare the nature of this invention and in what manner the
Fame is to be performed, to be particularly described and ascertained in and by the
following statement :-
An improved packing for stuffing boxes of steam engines, pumps, and other
mechanical appliances with its mode of manufacture. Its object is durability in
keeping a stuffing box perfectly tight with less friction, and to withstand a high
degree of pressure. It is composed of a fibrous material combined with a binding,
lubricating and heat resisting material. The fibrous material can be either asbestos
hemp, flax, jute or cotton or any other fibre either vegetable or mineral can be used,
either separate or two or more combined. The binding lubricating and heat
resisting materials, are soapstone French chalk, lampblack, resin, roach alum,
borax, graphite mixed together all made into a fine powder and thoroughly
incorporated together in a dry state, or the same can be mixed together and
ground into a fine smooth paste by mixing them with water to which has been
added a small quantity of size or glue or such like substance. The fibrous material
21

page_text: is spun into yarn two or more fold yarns can then be placed together to which can
be added several metal wires these yarns with the metal wires are then twisted or
platted together to size required, or the fibrous material and the metal wires can be
twisted or platted into a yarn, it is then platted or woven into tape or ribbon. As
it is being twisted platted or woven the binding lubricating and beat resisting
materials can be added either in a dry state or mixed with water or oil or the
fibrous material with the metal wires can be first platted or woven into tape or
ribbon the binding lubricating and heat resisting material afterwards added. The
tape or ribbon is then placed in several layers to thickness required and sewn
together in lengths it can then be pressed in a suitable machine to solidify it into
shape and size required. The fibrous material can be spun into yarn then woven
or platted into tape or ribbon without the metal wires, the binding lubricating and
heat resisting material added it is then placed in several layers to thickness required
and sewn together. Or one or more of the tape or ribbons with the metal wires in
it can be placed with one or more of the tape or ribbons without the metal wires in
several layers and sewn together in lengths wetted and pressed to size required any
number of layers of the fibrous tape or ribbon can be sewn together either with or
without the metal wires. Or any number of the fibrous tape or ribbon with the metal
wires and the binding lubricating and heat resisting material can be placed in
layers with any number of layers of the tape or ribbon without the metal wires and
sewn together for the above purpose a packing. The proportions in which the
different materials are used in the binding lubricating and heat resisting substance
are as follows:-Soapstone 15 parts, lampblack 4 parts resin 3 parts, roach alum
5 parts, borax 1 part, graphite 3 parts, these proportions can be varied to suit
different purposes. This packing is made either in continuous or definite lengths of
varied size shape and thickness and is cut to the proper length for the stuffing box
or joint when required to be used, or it can be cut and placed in suitable mould and
pressed so as to form rings to size required suitable for a stuffing box or joint.
The object of my invention is to produce a much more durable and efficient packing
to withstand a very high degree of beat and a very high degree of pressure with a
small amount of friction by the packing being at all times elastic and compressible,
caused by the packing being made into tape or ribbon placed in layers, with the
binding lubricating and heat resisting material and sewn together. By the packing
being placed in a stuffing box the flat side of the tape or ribbon to the rod allow of
its always being elastic and compressible.
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 :-
First. The twisting together of the fibrous material and the metal wires into a
yarn, either with or without the binding lubricating and heat resisting materials
substantially as and for the purpose herein described.
Second. The platting or weaving of the fibrous yarn with the metal wires into
tape or ribbon, either with or without the binding lubricating and heat resisting
material placing the tapes or ribbons in layers, and sewing them together
substantially as and for the purpose herein described.
Third. The platting or weaving of the fibrous yarn without the metal wires into
tape or ribbon, then adding the binding lubricating and heat resisting materials.
Placing the tape or ribbons in several layers, then sewing them together
substantially as and for the purpose herein described.
Fourth. The placing together of one or more layers of the tape or ribbons with
the metal wires, with one or more of the tape or ribbons without the metal wires,
in layers, the binding lubricating and beat resisting materials added to them. The
several layers are then sewn together substantially as and for the purpose herein
described.
Fifth. The binding lubricating and heat resisting materials as used with the
fibrous materials are soapstone 15 parts, lampblack 4 parts, resin 3 parts roach alum

page_text: 5 parts, borax 1 part graphite parts, these proportions can be varied, to suit
special purposes, substantially as and for the purpose herein described.
Sixth. The twisting together of the fibrous material and the metal wires into
yarn, and platting them together to size and shape required, as it is being platted
together the binding lubricating and heat resisting materials are added substantially
as and for the purpose herein described.
