IMPROVEMENTS IN TANNING
Year: 1862

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN TANNING."-A communication from abroad by Joseph Mouren, of
Marseilles, France.
Sealed the 21st April 1863, and dated the 23rd October 1862.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
23rd October 1862.
'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 "IMPROVEMENTS IN TANNING," (Communicated to me from abroad by Joseph
Mouren, of Marseilles, France,) to be as follows:-
This Invention consists in the employment of pressure to cause the tannin
to penetrate into the pores of the hides and skins undergoing the operation, as
hereafter explained. I take a vessel, calculated to withstand the pressure it is
to be subjected to, and line it with lead; I provide man-holes in the cover,
and make them to screw on and off. Connected with or standing upon a vat
containing tanning liquid I place two pumps, one communicates with the
upper part of the vessel, while the other opens into a channel running up and
down the side of the vessel, and formed with numerous perforations in the
face. The skins are placed in the vessel between two layers of tan, tanning

page_text: liquid is pumped into the vessel at the upper part, and the whole vessel is
filled, the pump communicating with the perforated channel is then used to
force in more tanning liquid to any required pressure, which is denoted by a
gauge on the pipe leading into the channel. The skins or hides are kept
under pressure for periods varying with their nature and the purposes to which
they are to be applied. The operation may be performed once or oftener.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 23rd April 1863.
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 Twenty-third day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth 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, 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 Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN TANNING," (communicated to me from abroad by
Joseph Mouren, of Marseilles, 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 Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Sael 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 Drawings hereunto
annexed, that is to say...

page_text: This Invention consists in the employment of pressure to cause the 'tannin
to penetrate into the pores of the hides and skins undergoing the operation, as
hereafter explained. I take a vessel, calculated to withstand the pressure it is
to be subjected to, and line it with lead; I provide, man-holes in the cover,
and make them to screw on and off. Connected with or standing upon a vat
containing tanning liquid I place two pumps, one communicates with the
upper part of the vessel, while the other opens into a channel running up
and down the side of the vessel, and formed with numerous perforations in
the face.
...
.
Figure 1 of the accompanying: Drawings is an external elevation, Figure 2
a plan, and Figure 3, a section thro' the line 1, 2, of Figures, 1 and 2 of an
apparatus for tanning according to this Invention; Figure 4 is a vertical
section of one of the covers of the man-holes, and of the seat for the same.
A is the vessel in which the tanning is performed, it is, by preference, round
at bottom, and is supported on a frame o; the vessel A is lined with lead, in
order that the iron or other material of which the vessel is formed may not
come in contact with the materials contained therein; B is a channel running
up and down the side of the vessel A, and formed with numerous perforations
in its face. On the top of the vessel A are two man-holes, closed by covers L
screwing on to the seats K; D, E, are two pumps standing on a vat C; the
pump E communicates through the pipe M and cock F with the upper part
of the vessel A, while the pump E communicates through the pipe N with the
channel B; G is a guage on the pipe N. The suction pipes of the two pumps
are furnished with metallic gratings H, H, to prevent the passage of foreign
matters. The cock J at the bottom of the vessel A is for the purpose of
drawing off the liquid therein when required.
The action is as follows:-The skins are placed in the vessel A between two
layers of tan, tanning liquid is pumped into the vessel A at the upper part by
means of the pump D, and the whole vessel is filled. The pump E com-
municating with the perforated channel B is then used to force in more
tanning liquid to any required pressure, which is denoted by the guage G on
the pipe N leading into the channel. The skins or hides are kept under
pressure for periods varying with their nature and the purposes to which they
are to be applied. The operation may be performed once or oftener.
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 as the "
ments in Tanning,"-
Improve-
First, the employment of pressure to cause the tannin to penetrate the
pores of the hides and skins, substantially as herein-before described.

page_text: Second, the apparatus for supplying the tanning liquid, constructed and
acting substantially in manner herein-before described and illustrated in the
accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-third day of April, One 5
thousand eight hundred and sixty-three.
