I RICHARD WALMSLEY HARRISON of 48 Darwen Street Blackburn in the county
of Lancaster Mill Furnisher do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PACKING FOR STEAM ENGINES, PUMPS STUFFING BOXES
AND OTHER JOINTS," to be as follows:-
--
The object of my invention is to make an effective packing for joints, partly
from lead or lead pipes, or similar soft metal with elastic, and other suitable
materials for cores or covering.
I employ soft metal tubing with an insertion of indiarubber, or indiarubber and
canvas, ordinary cotton, flax, asbestos cord, or other suitable soft, pliable, or elastic
material, so that when it is put into a joint and screwed up, it prevents the inside
surfaces of the metal from coming in contact, the core acting as a cushion makes
a more pliable joint than when soft metal alone is used, or the metal tubing may
be with or without the core, the outside being covered with indiarubber, india-
rubber and cloth, felt, asbestos, red-lead, or other packing material.
The covering may be put on by cementing, folding, twisting, wrapping, weaving,
or plaiting the material, on to the outside, I may insert or intermix metal wire or
strands along with the other elastic or fibrous materials either inside or outside,
the metal tubing, and I use any number of layers of soft metal tubing, and other
materials used in making packing, the tubing or packing when finished may be
round, oval, square, or other shapo in section, it is made in lengths, but we can
cut and join or piece the two ends together, so as to form any desired size or
shape of joint required.

I RICHARD WALMSLEY HARRISON of 48 Darwen Street Blackburn in the county
of Lancaster Mill Furnisher 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 my invention is to make an effective packing for joints partly
from lead or lead pipes or similar soft metal with fibrous elastic and other suitable
materials for cores or coverings.
I employ soft metal tubing with an insertion of indiarubber or indiarubber and
canvas, ordinary cotton, flax or asbestos cord, or other suitable soft pliable fibrous
or elastic material; so that when it is put into a joint and screwed up it prevents
the inside surfaces of the metal from coming in contact, the core acting as a cushion
makes a more pliable joint than when soft metal alone is used, or the metal tubing
may be with or without the core, the outside being covered with fibrous material,
indiarubber, indiarubber and cloth, felt, asbestos, powdered lead, or other packing
material.
The covering may be put on by cementing, folding, twisting, wrapping weaving,
or plaiting, the material on to the outside.
I may insert or intermix metal wire, or strands along with the other elastic or
fibrous materials, either inside or outside the metal tubing.
I may use any number of layers of soft metal tubing, and other materials used
in making the packing, The tubing or the packing when finished may be formed
oval, square, or other shape in section.
The packing is made in lengths but I can cut, and join or piece the two ends
together so as to form any desered size or shape of joint required.
DESCRIPTION OF DRAWINGS.
Fig. 1) shews a section of my solid metal tube packing, with core and covered
out side with indiarubber.
Fig. 2) shews a section of metal tube packing, with core and out side covered
with fine canvas.
Fig. 3. shews section of packing with two layers of metal tube with indiarubbor
inside, and outside, each of the metal tubes.
Fig. 4 shews section of canvas packing wrapped on metal tube, without core.
Fig. 5) shews section of canvas packing with metal tubing or tubular layers of
sheet metal wrapped up with the canvas.
Fig. 6 shews a section similar to Fig. 5 but with an indiarubber core.
Fig. 7 shews a section similar to Fig. 6 with only one tubular layer of sheet
metal.

page_text: Fig. 8 shews a section of packing with canvas and rubber core, with thin metal
sheet wrapped or rolled on in layers to form a tube, the out side is rubber and,
cotton felt.
Fig. 9 shows a sectional elevation of solid metal, tube packing, with core the.
outside being braided or plaited.
Fig. 10 shews a section of canvas packing with layer of metal tubing the edges
of which meet or join made out of metal sheet cut to the exact width, so as to
just wrap once around the core in tubular form.
A are the metal tubes, B are the cores C is the rubber, canvas, or other covering.
The metal may be in solid tube then filled inside and covered on the out side, with
other materials suitable for use as packing.
I may take a core of rope, indiarubber, or other suitable packing material and
roll on one or more layers of metal sheet, cut to the width required to form a tube,
or I may force or draw upon the core or rope a metal tube by pressure through dies
of any required thickness the outside of the metal is then covered with the required
material suitable for use as packing.
I may use two or more layers of the soft metal sheet or tubing along with other
materials used in making the packing in the same manner as described for making
one layer.
These packings can be formed into endless rings and washers.
More particularly those made with the solid metal tubing which can be cut
the required lengths then fused or soldered together by displacing a portion of the
covering from the metal until it is pieced then the covering is replaced on the metal
and the joint made good.
I also take a core of indiarubber fibrous rope or other suitable packing material
and then roll upon it soft metal sheet with or without canvas felt or other materials
(see Figs. 7 and 10) to form a tube the metal is cut in suitable widths to form one
or more tubes or layers of metal with canvas felt or other materials which is then
continued to be rolled on, plaited or otherwise until the packing is made the desired
thickness (see Fig. 5 6 7 and 9) for covering I may or may not braid or plait a
covering on the outside or between the layers of these packings, and the interior
metal tube may be with or without core.
By the application of metal as described when used for joints, it can be made to
withstand any working pressure that may be brought to bear against it whilst it
requires less screwing down than most other packings, and the interior portion of
the packing is protected from injury by the metal tube, thus making it a very
solid yet elastic packing, it has the advantage of being able to be bent or formed,
and retained in any desired shape of joint.
When used in glands or stuffing boxes the metal preserves the interior portion
of the packing so that the rubber core, other materials, and lubricants, are kept
more in their natural state to better serve the purposes for which they are intended
and the metal itself also acts as an antifriction medium thus making it a very
pliable and durable packing. When manufacturing these packings in the various
forms described I apply or add any of the materials that are used in the manufac-
ture of packings, namely; Vulcanized Indiarubber, Indiarubber Solution, fibrous
materials, Asbestos, Plumbago, Chalk, Mica, powdered lead, Oil, Greace, and other
lubricants and heat resisting materials which may be considered necessary for the
purpose.
These packings.can be formed round, square, Oval, or other desired shape in
section by compression or otherwise.
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
(1.) The use of soft solid metal tubing in combination with other materials for
packing as shewn and described.

page_text: (2.) Soft metal drawn or forced on to a core or rope in the form of a tube as a,
covering for the core or packing as shewn and described.
(3.) The use of soft metal sheet cut in suitable widths and wrapped or rolled in
one or more thicknesses on the cores of packing as shewn and described.
(4.) Packing composed of one or more layers of metal sheet tubing or tubes as 5
shewn and described.
