page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
WALL, of India Road, East India Road, in the County of Middlesex, Surgeon,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourteenth day of
October, One thousand eight hundred and forty-seven, in the eleventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Arthur Wall, my exors, adiñors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said Arthur Wall, my
exors, admors, and assigns, or such others as I, the said Arthur Wall, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the terin of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A NEW OR
IMPROVED APPARATUS FOR AND METHOD OF SEPARATING OXIDES FROM THEIR COM-
POUNDS AND EACH OTHER;" in which said Letters Patent is contained a proviso
that I, the said Arthur Wall, shall cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in

page_text: and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Arthur Wall, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say
My Invention consists of so arranging magnets that they may be made the
means of separating oxides of iron from other oxides and other compounds
containing them.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 is a longitudinal elevation of an apparatus constructed according
to my Invention, partly in section, and Figure 2 is a plan thereof. In each
of these Figures the same letters of reference indicate similar parts. The
machine or apparatus is so constructed and arranged that a series of magnets
may come successively into action on oxides of iron mixed with other oxides
or with other matters, and thus separate the oxides of iron from the other
oxides or from other matters. a, a, are two frames or drums, on which is an
endless strap of leather or other suitable flexible material. On the surface of
such endless strap are fixed a series of magnets b, b, and in connection there-
with are thin iron or steel plates c, c, which are split into narrow strips, and
which are turned edgewise so as to leave spaces between them. The manner
in which I connect the plates c is by having in each case two magnets, one
laid and fastened down on the other, there being placed between each pair of
limbs a plate c, as shewn; but other modes of fixing the magnets, and con-
necting plates c therewith, may be resorted to in carrying out my Invention.
d is an inclined plane on to which the ground ore is supplied, e being a
trough which receives the ore. f is an inclined plane at the other end of the
trough, and g are magnets with the poles reversed, by which means, when
the plates c come up charged with oxides of iron, they will drop off by the
neutralizing effect produced by the magnets g on the magnets b. In using
this apparatus, supposing iron is to be separated from copper ore, the ore is to
be first roasted and ground, and placed on the inclined platform d, and motion
is to be given to the drums or frames carrying the endless strap, by which
the plates c will enter amongst the ground matter, and the oxides of iron will

page_text: be attracted by and separated from the other oxides or other matters; and thus
will the oxides of iron be separated from other oxides and from other matters,
and it will leave the copper ores in a better condition to be dealt with in
manufacturing copper. And in this manner may oxides of iron be separated
from other ores or matters than copper ores. In the above description I have
spoken only of permanent magnets, because I believe them to be most suitable
for carrying out my Invention; but I do not confine myself thereto, as electro-
magnets may be employed in place thereof.
Iaving thus described the nature of my Invention, and the best means with
which I am acquainted for performing the same, I would wish it to be under-
stood that I do not confine myself to the details as shewn and described; but
what I claim is the arranging of a series of magnets into an apparatus for
separating oxides of iron from other oxides and from other matters.
In witness whereof, I, the said Arthur Wall, have hereunto set my band
and seal, this Fourteenth day of April, in the year of our Lord One
thousand eight hundred and forty-eight.
