Year: 1872

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN METALLIC PACKING FOR MAKING
STEAM, AIR, GAS, OR WATER-TIGHT JOINTS."-A communication from
abroad by Frank Watson Campbell and Ira Saunders, both of
Chicco Illinois United States of America.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 31st May 1872.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
Dature of the said Invention for "IMPROVEMENTS IN METALLIC PACKING
FOR MAKING STEAM, AIR, GAS, OR WATER-TIGHT JOINTS," a communication,
to be as follows:-
This Invention relates to an improved metallic packing for making
steam, air, gas, or water-tight joints in cylinders, pipes, and other

page_text: apparatus for holding or conducting fluids, and consists in using a
rod of copper, lead, or other soft or compressible metal, rolled or
drawn into the proper form, so that the parts connected being forced
against the edges of the packing the same may be readily compressed
to form between the packing and the surfaces between which it is
compressed a joint impervious to air, steam, gas, water, or other fluid.
The aforesaid rod is formed with edges on its upper and lower faces,
preferably with two edges, as two packings may thus be cheaply formed.
The said rod is rolled or drawn through steel plates into the required
form, and in using it one side is embedded into one of the two surfaces
between which the joint is to be made, leaving the opposite edges
projecting. The rod as above described is composed of copper, lead, or
other compressible metal, and when the other surface to be connected is
forced against it with power sufficient to compress it the said rod will be
forced into any irregularities of surface, thereby forming an impervious
joint. The aforesaid rods may be rolled or drawn into the form of
squares, and one or more of said rods may be used, or the squares may
be duplicated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 29th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year
of Her reign, did for Herself, Her heirs and successors, give
and grant unto me, the said William Robert Lake, Her special licence,
that I, the said William Robert Lake, my executors, administrators, and
assigns, or such others as I, the said William Robert Lake, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
METALLIC PACKING FOR MAKING STEAM, AIR, GAS, OR WATER-TIGHT JOINTS,"
a communication to me from abroad by Frank Watson Campbell and
Ira Saunders, both of Chicago, Illinois, United States of America, upon
the condition (amongst others) that I, the said William Robert Lake,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification :-
This Invention relates to an improved metallic packing for making
steam, air, gas, or water-tight joints in cylinders, pipes, and other apparatus
for holding or conducting fluids, and consists in using a rod of copper,
lead, or other soft or compressible metal rolled or drawn into the proper
form, so that the parts to be connected being forced against the edges
of the packing the same may be readily compressed and will form
between the packing and the surface between which it is compressed
a joint impervious to air, steam, gas, water, or other fluid.
In the accompanying Drawing the said Invention is shown as applied
to a steam chest, but it is not limited to this or any other special
application.
DESCRIPTION OF THE DRAWING.
Figure 3 is a section of a packing rod having square sides.
Figure 4 is another section of a packing rod, the opposite faces of
which are round.
The aforesaid rods A are formed with edges B on their upper and lower
faces, preferably with two edges, as two packings may thus be cheaply
formed. The rod is rolled or drawn through steel plates into the form

page_text: shown in Figures 2, 3, or 4; in using it one side is embedded into one
of the two surfaces between which the joint is to be made, leaving the
opposite edges projecting as shown. The rod as above described is
composed of copper, lead, or other compressible metal, and when the
other surface to be connected is forced against it with power sufficient &
to compress the rod it will assume a form corresponding with any
irregularities of surface, thereby forming an impervious joint.
The aforesaid packing rods may be rolled or drawn into the form of
squares and arranged as set forth, and one or more of such rods may be
used, or the squares may be duplicated as represented in Figures 2, 3,
and 4, if preferred.
Having thus fully described the said Invention as communicated
to me by my foreign correspondents, and the manner of performing the
same, I wish it understood that I claim, metallic packing for forming
steam, air, gas, or water joints, consisting of pieces of a compressible.
metal rolled or drawn into the forms herein set forth and forming joints
between opposed faces by compression in the manner described.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and scal, this Twenty-ninth day of November,
in the year of our Lord One thousand eight hundred and seventy-
two.
Witness,
W. J. LOWE.
