CERTAIN IMPROVED APPARATUS FOR WASHING AND CLEANSING ORES
Year: 1856

page_text: LETTERS PATENT to Jean Baptiste Honoré de Roussen, of 39, Rue de
l'Echiquier, Paris, in the Empire of France, and of No. 4, South Street,
Finsbury, London, for the Invention of "CERTAIN IMPROVED APPARATUS
FOR WASHING AND CLEANSING ORES."
Sealed the 17th March 1857, and dated the 19th September 1856.
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Honoré de
Roussen at the Office of the Commissioners of Patents, with his Petition,
on the 19th September 1856.
I, JEAN BAPTISTE HONORÉ DE ROUSSEN, of 39, Rue de l'Echiquier, Paris, in
the Empire of France, and of No. 4, South Street, Finsbury, London, do
hereby declare the nature of my Invention of "CERTAIN IMPROVED APPARATUS
FOR WASHING AND CLEANSING ORES," to be as follows, that is to say :-
This Invention consists of an improved construction of sieve and brush for
washing and purifying metallic ores.
The sieve is composed of a wooden frame of suitable dimensions, in which
are placed thirty-six or any convenient number of squares formed of cast iron
or other metal. Each square is cast with twenty-six (more or less) parallel
bars, with one in the middle, at right angles to the others, for strengthening and
uniting them together. In this manner is formed a sieve having small inter-
stices or spaces for the impurities contained in the ore to pass through.

page_text: The brush employed in connection with the sieve consists of a hard piece of
wood of an oblong shape, and has several rows of square holes formed in it, in
which holes square iron or other metallic rods or teeth of different lengths are
fixed by nuts. Over the heads of the rods is secured a wooden cap or cover,
to which are fastened two moveable forks having long handles attached to them
for working the brush.
When using the sieve, it is placed in water at about three inches from the
surface, and the ore to be cleansed is thrown into it in considerable quantities;
the water and ore are then agitated by the brush, which causes the earthy and
other impurities to pass through the interstices of the sieve, and by this
operation the ore becomes purified.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Baptiste Honoré de Roussen, in the Great Seal Patent
Office on the 18th March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE HONORÉ DE ROUSSEN, of 39, Rue de l'Echiquier, Paris, in the
Empire of France, and of No. 4, South Street, Finsbury, London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did for Herself, Her heirs and successors, give and grant unto me, the said
Jean Baptiste Honoré de Roussen, Her special license that I, the said Jean
Baptiste Honoré de Roussen, my executors, administrators, and assigns, or
such others as I, the said Jean Baptiste Honoré de Roussen, 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 "CERTAIN IMPROVED APPARATUS FOR WASHING AND
CLEANSING ORES," upon the condition (amongst others) that I, the said Jean
Baptiste Honoré de Roussen, by an instrument in writing under my hand and
seal, 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 Seal Patent Office within six calendar months next and
immediately after the date of said Letters Patent.

page_text: NOW KNOW YE, that 1, the said Jean Baptiste Honore de Roussen, do
hereby declare the nature of my 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 hereto
annexed, and to the figures and letters marked thereon, that is to say:-
This Invention consists of an improved construction of sieve and brush for
washing and purifying metallic ores.
The sieve is composed of a wooden frame of suitable dimensions, in which
are placed thirty-six or any convenient number of squares formed of cast iron
or other metal. Each square is cast with twenty-six (more or less) parallel
bars, with one in the middle, at right angles to the others, for strengthening and
uniting them together. In this manner is formed a sieve having small inter-
stices or spaces for the impurities contained in the ore to pass through.
The brush employed in connection with the sieve consists of a hard piece of
wood of an oblong shape, and has several rows of square holes formed in it, in
which holes square iron or other metallic rods or teeth of different lengths are
fixed by nuts. Over the heads of the rods is secured a wooden cap or cover,
to which are fastened two moveable forks having long handles attached to them
for working the brush.
When using the sieve, it is placed in water at about three inches from the
surface, and the ore to be cleansed is thrown into it in considerable quantities;
the water and ore are then agitated by the brush, which causes the earthy and
other impurities to pass through the interstices of the sieve, and by this
operation the ore becomes purified.
In order that the Invention may be better understood, I will now refer to
the Figures on the Sheet of Drawings.
Figure 1 is a plan of the sieve, which consists of a wooden frame A, about
It is
nine feet long by about eight feet wide, or other suitable dimensions.
furnished with cross bars A', on which are placed the small squares B forming
the sieve. These squares are shewn on a larger scale, Figure 2, and are con-
structed of wrought or cast iron, about seventeen inches in length, fifteen in
breadth, and about half an inch in thickness. The square is formed with
twenty-six (more or less) parallel bars C, united and strengthened by the
central bar D at right angles to them; these bars may be of an angular shape,
as shewn in the plan, Figure 3, and section, Figure 4. The sieve is formed by
filling up the frame with a series of these squares properly adjusted. The
impurities contained in the ore, while undergoing the washing process, pass
through the small interstices or spaces E.
The brush employed in the washing process is shewn in plan, Figures 5 and 6.

page_text: It consists of a hard piece of wood, forming the back, of about fifteen inches
in length, eight inches in breadth, and one inch in thickness. It is pierced
with a number of holes, in which are fixed by nuts F the screw pins or teeth G
of different lengths. The row of pins No. 1 are half an inch, the row No. 2
one-third, and the row No. 3 one-fourth of an inch in length. Upon the top
of the wooden cover H of the brush are placed two moveable forks I, to which
are fastened long handles J for working the brush.
When using the sieve, it is placed in water at about three inches from the
surface, or under a stream of water; the water and ore are then agitated by the
brush, which causes the earthy and other impurities to pass through the inter-
stices of the sieve, and by this operation the ore becomes washed and purified.
Having now described the nature of my said Invention, and in what manner
the same is to be performed, I would have it understood that I do not confine
myself to the precise details herein laid down, so long as the peculiar character
of my Invention be retained; but what I claim is, the construction and
employment of the sieve and brush, as herein-before described, and represented
in the annexed Drawings, for washing and purifying metallic ores.
In witness whereof, I, the said Jean Baptiste Honoré de Roussen, have
hereunto set my hand and seal, this Sixteenth day of March, in the
year of our Lord One thousand eight hundred and fifty-seven.
