IMPROVEMENTS IN APPARATUS FOR THE RE-BURSTING OF ANIMAL CHARCOAL
Year: 1864

page_text: LETTERS PATENT to John Frederick Drinjes, of Fieldgate Street, White-
chapel in the County of Middlesex, Engineer, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR THE RE-BURSTING OF ANIMAL CHARCOAL"
PROVISIONAL SPECIFICATION left by the said John Frederick Brinjes at
the Office of the Commissioners of Patents, with his Petition, on the
1st November 1864:
I, JOHN FREDERICK BRINJES, of Fieldgate Street, 'Whitechapel, in" the
County of Middlesex, Engineer, do hereby declare the nature of, the said
Invention for "IMPROVEMENTS IN APPARATUS FOR THE RE-BURNING OF ANIMAL
CHARCOAL," to be as follows:-
This Invention relates to improvements in the apparatus for re-burning
animal charcoal, for which Letters Patent were granted to me, on or about
the 23rd of April 1864, No. 1038, whereby such apparatus is rendered more
simple in its construction.
According to this' Invention it is proposed to replace the moveable or self-
adjusting doors or vanes inside the cylinders or retorts by double inclined
pieces fixed immoveably to the retort between each of the internal rings or
flanges, and opposite to the openings therein, the circular, reciprocating, or
to-and-fro motion of the retort causing the charcoal to slide along the inclines
and so pass from one space to another throughout the length of the cylinder
or retort. Or, if preferred, the internal rings or flanges may be either wholly

cylinder or retort serving by the aid of the to-and-fro circular motion thereof
to cause the charcoal to travel from end to end of such retorts.
In lieu of making the cooling drum with an inner and an outer skin, as
described in the said Specification. it may be made with a single skin only,
and caused to revolve in a trough or tank of cold water. or a stream of cold
water may be caused to flow over its surface, thereby more rapidly cooling its
contents.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Frederick Brinjes in the Great Seal Patent Ollice on
the 1st May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FREDERICK BRINJES, of Fieldgate Street. Whitechapel, in the County of
Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent. Majesty Queen Victoria, by ller Letters
Patent, bearing date the First 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 John Frederick Brinjes, Her special license that I, the said
John Frederick Brinjes, my executors, administrators, and assigns, or such
others as I, the said John Frederick Brinjes, my executors, administrators, or
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 "IMPROVEMENTS IN APPARATUS FOR THE RE-BURNING OF
ANIMAL CHARCOAL," upon the condition (amongst others) that I, the said John
Frederick Brinjes, my executors or administrators. by an instrument in writing
under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same 10 he 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 1, the said John Frederick Brinjes, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say:-
My said Invention relates to improvements in the apparatus for re-burning
animal charcoal for which Letters Patent were granted to me on or about the
23rd of April 1864, No. 1038, whereby such apparatus is rendered more
simple in its construction.
According to this Invention it is proposed to replace movable or self-
adjusting doors or vanes inside the cylinders or retorts by double inclined
pieces fixed immoveably to the retort between each of the internal rings or
flanges, and opposite to the openings therein, the circular, reciprocating, or
to-and-fro motion of the retort causing the charcoal to slide along the inclines,
and so pass from one space to another throughout the length of the cylinder
or retort. Or, if preferred, the internal rings or flanges may be either wholly
or partly dispensed with, the double inclined pieces fixed to the interior of the
cylinder or retort serving, by the aid of the to-and-fro circular motion thereof.
to cause the charcoal to travel from end to end of such retorts.
And in order that my said Invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose shall
refer to the several Figures on the annexed Sheet of Drawings, the same
letters of reference indicating corresponding parts in all the Figures.
Fig. 1 of my Drawings represents a sectional elevation of a pair of retorts,
showing my improved appliances for causing the animal charcoal to travel
along them, the retorts being fully represented in complete working order;
Fig. 2 is a sectional plan of one of the retorts, and also illustrates in plan the
appliances above referred to; Figs. 3 and 4 are external front and back
elevations, corresponding to Fig. 1. showing the general arrangement and
mode of working the apparatus.
A and B are the upper and lower retorts respectively made to reciprocate
on their axes in any convenient manner, and provided inside with a series of
internal rings or flanges C, C, in combination with the double inclined
projections D, D, which may be either cast in one with the retort, as shewn
in the Drawings (Figs. 1 and 2) or made separately and fitted inside the
retorts by screws, rivets, or otherwise. These double inclined projections are
situate between each of the adjoining rings or flanges C, and in the line of the
openings or gaps left in such rings or flanges, and are placed in reverse
directions in each retort, as the charcoal has to travel in opposite directions
along the two retorts. When the retort turns in one direction, the animal
charcoal, after being raised to a certain height by the projecting ledges E
inside the retorts. will descend and fall against. the inclined face a of the

page_text: double inclined projection D, and will be thereby deflected or diverted laterally
into the next adjoining space, and when the retort reverses its motion the
charcoal will be elevated on the opposite side, and will then fall against the
inclined face b of the double inclined projection, and by it be directed into the
next space, and so on continuously until it is discharged down the pipe F
leading to the lower retort B, through which it is caused to travel in the
same manner as that already described with reference to the retort A, and is
finally discharged into any ordinary or other cooling apparatus G. In some
cases in lieu of combining the double inclined projections D with the internal
rings or flanges C, these projections may be employed without the said rings
or flanges C.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, the application and use to and in
retorts employed in the re-burning of animal charcoal of double inclined
projections, either alone or in combination with internal rings or flanges
having openings left therein, substantially in the manner and for the purpose
herein-before described, and illustrated by my Drawings.
In witness whereof, I, the said John Frederick Brinjes, have hereunto
set my hand and scal, the Twenty-seventh day of April, One thousand
eight hundred and sixty-five.
JOHN FREDERICK BRINJES. (L.S.)
