Year: 1868

page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John
Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "A
PROCESS HAVING FOR OBJECT THE SEPARATION OF ANIMAL FROM VEGETABLE
SUBSTANCES IN TEXTILE FABRICS, RAGS, OR ANY OTHER MATERIAL
CONTAINING THEM."-A communication from abroad by Philibert
Antoine Hippolyte Schlosser, of 39, Faubourg St. Martin, Paris,
France.
PROVISIONAL SPECIFICATION left by the said William Edward
Gedge at the Office of the Commissioners of Patents, with his
Petition, on the 14th February 1868.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,
of No. 11, Wellington Street, Strand, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for
"A PROCESS HAVING FOR OBJECT THE SEPARATION OF ANIMAL FROM VEGETABLE
SUBSTANCES IN TEXTILE FABRICS, RAGS, OR ANY OTHER MATERIAL CONTAINING
THEM," a communication to me from abroad by Philibert Antoine

follows:-
The object of this process is to utilize the influence of the gases and
vapours of acids generally on vegetable fibre and to employ their action
upon rags (cotton warp), namely, those composed by juxtaposition of
cotton, hemp or flax, and wool, and sometimes silk.
"This operation consists (using chlorhydric acid vapours),―
Firstly. In spreading the rags on hurdles.
Secondly. In placing them in an oven chamber suitably constructed
'for the reception of the acid vapours while capable of supporting heat.
Thirdly. In introducing the hurdles suitably furnished and arranged
fin layers, regulating the disengagement of the acid vapours in proportions
sand arrangements ad hoc according to the quality and quantity of the
material under treatment.
Fourthly. In arresting the disengagement when the disaggregating
influence has been attained, purging the apparatus and opening the
.registers for the arrival of the heat, which is allowed to act until the
moment when by simple frictions the vegetable matter will fall in
<dust.
Fifthly. In submitting these rags to the action of a beating engine
from which the wool will issue free and without deterioration in rovings
or shreds suitable for re-employment, while the vegetable matter will
.be. collected to be used in chemical productions or as manure.
Sixthly. In dyeing, unravelling, carding, and so on by ordinary
processes, as may be desired by the operator.
By manufacturing sulphate of soda beneath the oven chamber a
profitable use is made on the one hand of the greater part of the
chlorhydric acid vapours (mostly a source of embarassment), and on
the other hand of the waste heat of the apparatuses in which the
-sulphate of soda is manufactured, an economical extraction being thus
obtained, as also by utilizing the hypoazotic vapours obtained in the
manufacture of iron mordants for dyeing and printing.
In some cases
the hurdles may be replaced by a cast-iron case or drum arranged so. as
to turn on bearings in the masonry of the oven. The movement, given
to the case causes the rags to constantly present fresh surfaces to the
influence of the gases or vapours as well as of the heat, which act on

page_text: the rags by passing through openings in the sides of the apparatus.
In the treatment of some materials a moist vaporization prépares and
facilitates the success of the operation.
In conclusion, this process consists in the separation of vegetable from
animal substances by means of acid vapours acting in an oven or kiln.
into which the materials are introduced.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 13th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD. GEDGE, of the Firm of John Gedge and Son, of No. 11,
Wellington Street, Strand, in the County of Middlesex, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Fourteenth day of February, in. the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Gedge, Her special
licence that I, the said William Edward Gedge, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward
Gedge, 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 Invention. for
"A PROCESS HAVING FOR OBJECT THE SEPARATION OF ANIMAL FROM VEGETABLE.
SUBSTANCES IN TEXTILE FABRICS, RAGS, OR ANY OTHER MATERIAL CONTAINING.
THEM,"
a communication to me from abroad by Philibert Antoine
Hippolyte Schlosser, of 39, Faubourg St. Martin, Paris, France, upon
the condition (amongst others) that I, the said William Edward Gedge,.
my executors or.admintstrators, 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

page_text: 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 William Edward Gedge, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
rained in and by the following statement :-
The object of this process is to utilize the influence of the gases and
vapours of acids generally on vegetable fibre and to employ their action
upon rags (cotton warp), namely, those composed by juxtaposition of
cotton, hemp or flax, and wool, and sometimes silk.
This operation consists (using chlorhydric acid vapours),―
Firstly. In spreading the rags on hurdles.
Secondly. In placing them in an oven chamber suitably constructed
for the continuous reception of the acid vapours while capable of
supporting heat.
Thirdly. In introducing the hurdles suitably laden and arranged in
layers and in regulating the disengagement of the acid vapours, and
keeping them in proportions and arrangements ad hoc according to the
quality and quantity of material under treatment.
Fourthly. In arresting the disengagement when the disaggregating
influence has been attained, purging the apparatus and opening the
registers for the arrival of the heat, which is allowed to act until the
moment when by simple frictions the vegetable matter will fall in
dust.
Fifthly. In submitting these rags to the action of a beating engine
from which the wool will issue free and without deterioration in rovings
or shreds suitable for re-employment, while the vegetable matter will be
collected to be used in chemical products or as manure.
Sixthly. In dyeing, unravelling, carding, and so on by ordinary
processes, as may be desired.
By manufacturing sulphate of soda beneath the oven chamber a
profitable use is made on the one hand of the greater part of the
chlorhydric acid vapours (mostly a source of embarassment), and on
the other hand of the waste heat of the apparatuses in which the sulphate
of soda is manufactured, an economical extraction being thus obtained,
as also by utilizing the hypoazotic vapours obtained in the manufacture
of iron mordants for dyeing and printing. In some cases the hurdles

bearings in the masonry of the oven. The movement given to the case
or drum causes the rags to constantly present fresh surfaces to the
influence of the gases or vapours as well as of the heat acting on the
rags by passing through openings in the sides of the apparatus.
moist vaporization prepares and facilitates for certain materials the
success of the operation.
A
To sum up, the object of this process is the separation of the
vegetable from the animal substances by means of acid vapours
acting in an oven or kiln into which the materials to be treated are
introduced.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and seal, this Thirteenth day of August,
in the year of our Lord One thousand eight hundred and sixty-
eight.
