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
METHOD OF AND IMPROVED APPARATUS FOR REVIVIFYING ANIMAL BLACK."-
A communication from abroad by Jean, Baptiste Felix Trolliet, of
Lyons, France:
Sealed the 23rd September 1864, and dated the 26th March 1864.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his'
Petition, on the 26th March 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 METHOD OF AND IMPROVED APPARATUS FOR REVIVIFYING
ANIMAL BLACK," to be as follows:-
This Invention consists in progressively drying and heating animal black.
until revivified, and then in cooling the same, and the improved apparatus
consists of an oven with retorts placed horizontally, and superposed; the fire
is inside the lower retort, and the upper retort is heated by flues from the
lower retort. The top of the apparatus serves for drying the black, and it is
progressively heated by passing through passages provided for that purpose
around the upper retort and between it and the flues surrounding it, and then
around the lower retort and its flues. On leaving this passage the black. is

page_text: revivified, and continues on into a cooling chamber furnished with cold air
flues, and traversed by air pipes below the lower retort. At the bottom of
this chamber doors are provided through which the revivified black is
withdrawn.
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 26th September 1864.
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-sixth day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh 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 1, 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 "AN IMPROVED METHOD OF AND IMPROVED APPARATUS FOR REVIVIFYING
ANIMAL BLACK," (communicated to me from abroad by Jean Baptiste Felix
Trolliet, of Lyons, France,) upon the condition (amongst others) that I, the said
Richard Archibald Brooman, my executors or administrators, by an instru-
ment 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 sanie 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 Drawings hereunto
annexed, that is to say:-
This Invention consists in progressively drying and heating animal black

page_text: until revivified, and then in cooling the same, and the improved apparatus
consists of an oven with retorts placed horizontally, and superposed; the fire is
inside the lower retort, and the upper retort is heated by flues from the lower
retort. The top of the apparatus serves for drying the black, and it is
progressively heated by passing through passages provided for that purpose
around the upper retort and between it and the flues surrounding it; and then
around the lower retort and its flues.. On leaving this passage the black is
revivified, and continues on into a cooling chamber furnished with cold air.
flues, and traversed by air pipes below the lower retort. At the bottom of
this chamber doors are provided through which the revivified black is
withdrawn.
The retorts may be made either with single sides, and with external plates
to form the passages through which the black passes, or they may be made
with double sides without external plates, in which case the black passes.
through the passages formed by the two sides.
Figure 1 of the accompanying Drawings is a vertical section taken through
two horizontal superposed retorts of an apparatus constructed according to
this Invention; Figure 2 is a horizontal section through the line 1, 2, of
Figure 1. In this arrangement the retorts have only single sides. Figure 8
is a transverse vertical section of a similar apparatus with the retorts formed
with double sides; Figure 4-is a longitudinal vertical section, and Figure 5 a
horizontal section through the line 3, 4, of Figure 3. The same letters
indicate the same parts in all the Figures.
A is the lower retort, which receives the flame and products of combustion
from the fire-place S (Figures 4 and 5); B, B, Figures 1 and 3 are flues into
which the products of combustion pass from the retort A; C, C³, Figures
1 and 2, are plates or divisions of iron, or of refractory material forming one
side of the flues. In the arrangement represented in Figures 3, 4, and 5,
these plates are replaced by the second or double side of the retorts. D is the
upper retort, which is heated by the products of combustion passing through
the flues B, B, and E, E; F, F, are other flues in which the products of
combustion circulate before passing off into the chimney G; these flues heat
the top H of the apparatus on which the animal black to be revivified becomes
dried before being heated in the apparatus, as about to be described. The
black is introduced into the apparatus by the orifices I, and becomes pro-
gressively heated in passing down through the passages J, J, and L, L; by
the time it reaches the bottom of the passages L, L, it has become sufficiently
heated to effect its revivification, it then falls into a cooling chamber M
surrounded with cold air flues N, N; O, O, are plates with doors P, through

page_text: which the revivified black is withdrawn; Q, Q, are passages for wagons for
carrying away the black as it leaves the chamber M; R, R, are air pipes (of
which there may be one or more): terminating, in the fire-place, and through
which a current of cold air is kept up by the draught through the fire.
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,
First, constructing apparatus for revivifying animal black in which the.
drying and heating of the. black until revivified are performed progressively in.
passages surrounding the retorts, and, in which the black after revivification.
is cooled in a cooling, chamber, all substantially in. manner herein-before
described and illustrated in the accompanying Drawings.
Second; constructing apparatus for revivifying animal black with two
horizontal superposed; retorts, the interior, of the lower of which is submitted
to the action of the fire, as herein-before, described. .
In witness whereof, I, the said Richard 'Archibald Brooman, have here-
unto set my hand and seal, this Twenty-sixth day of September, One
thousand eight hundred and sixty-four..
A BROOMAN Gal
