Year: 1864

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet. Street,
in the City of London, Patent Agent, for the Invention of "AN IMPROVED
PACKING FOR STUFFING BOXES."-A communication from abroad by Alix
Laconfourque and Grand Perrin, of Paris, France.
Sealed the 3rd February 1865, and dated the 7th November 1864.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
7th November 1864.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "AN IMPROVED PACKING FOR STUFFING BOXES," to be as follows:-
This Invention consists in substituting for the ordinary hemp and combustible
packing an incombustible metallic thread packing, which retains the ad-
vantages due to a filamentous form. The fineness of the thread affords
flexibility to the packing without the disadvantage of being combustible. The
stuffing box is provided in the inside with a metallic thread rolled in multiple
spirals; upon this thread I place a ring composed of rope or strands of textile
or mineral material; such for example, as amianthus.

by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 6th May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of November, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, 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 Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED PACKING FOR STUFFING BOXES," (communicated to
me from abroad by Alix Laconfourque and Grand Perrin, of Paris, France,)
upon the condition (amongst others) that I, the said Richard Archibald
Brooman, 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 sanio
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, 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 thereof, reference being had to the Drawing
hereunto annexed, that is to say:-
This Invention consists in substituting for the ordinary hemp and combustible
packing an incombustible metallic thread packing, which retains the advantages
due to a filamentous form. The fineness of the thread affords flexibility to
the packing without the disadvantage of being combustible. The stuffing box
is provided on the inside with a metallic thread rolled in multiple spirals;
upon this thread I place a ring composed of rope or strands of textile or
mineral material, such for example, as amianthus.

page_text: The accompanying Drawing represents in vertical section a stuffing box in
which a metallic thread packing is employed.
a is the packing composed of threads of brass or other metal rolled in
multiple spirals round the rod b, so as to fill up the space between the rod and
the cone or socket c fitted in the box d; g is a ring or wrapping of amianthus
or other suitable material over the thread a.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim forming packing
for stuffing boxes of incombustible metallic thread, substantially as herein-
before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fourth day of May, in the year of
our Lord One thousand eight hundred and sixty-five.
R. A. BROOMAN. (L.S.)
