Year: 1860

page_text: LETTERS PATENT to John Parkinson, of the Victoria Brass Works, Bury,
in the County of Lancaster, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SEPARATING SMALL PARTICLES OF IRON OR STEEL FROM
BRASS AND OTHER METALS OR MATERIALS."
Sealed the 4th October 1860, and dated the 23rd April 1860.
PROVISIONAL SPECIFICATION left by the said John Parkinson at the
Office of the Commissioners of Patents, with his Petition, on the
23rd April 1860.
I, JOHN PARKINSON, of the Victoria Brass Works, Bury, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR SEPARATING SMALL PARTICLES OF IRON OR.
STEEL FROM BRASS AND OTHER METALS OR MATERIALS," to be as follows:-
The object of my Invention is principally intended to cleanse brass filings,
borings, or turnings, that is to say, to remove the steel and iron filings,
borings, or turnings from them, so that the brass may be again used for
making brass castings or otherwise. In performing my Invention, I place a
number of magnets in a spiral line on the circumference of a roller revolving
in a trough, one end of which has a hopper into which the mixed filings,
borings, or turnings are fed, and the other end is open to discharge them

page_text: when cleansed. The filings, borings, or turnings, are traversed along the
trough by the magnets. The discharge from the hopper is regulated by an
agitator acted upon by the roller or other part of the machinery. The par-
ticles of steel and iron which adhere to the magnets are brushed off and
deposited into a box by a revolving brush or other suitable agent. It is
evident that this improved machinery may be used to separate small particles
of iron or steel from any other metals or materials.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Parkinson in the Great Seal Patent Office on the
22nd October 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PARKINSON, of the Victoria Brass Works, Bury, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said John Parkinson, Her special licence, that I, the said John Parkinson,
my executors, administrators, and assigns, or such others as I, the said
John Parkinson, 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, usc,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY FOR SEPARATING SMALL PARTICLES OF IRON OR STEEL FROM BRASS
AND OTHER METALS OR MATERIALS," upon the condition (amongst others) that
I, the said John Parkinson, my executors or administrators, 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 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 John Parkinson, 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, that is to say:-

page_text: The object of my Invention is principally to cleanse brass filings, borings,
or turnings, that is to say, to remove the small particles of steel and iron
from them so that the brass may be again used for making brass castings or
otherwise. In performing my Invention, I place a number of magnets in a
spiral line on the circumference of a roller, revolving in a trough, one end of
which has a hopper, into which the mixed filings, borings, or turnings are
fed, and the other end is open to discharge them when cleansed. The filings,
borings, or turnings are traversed along the trough by the magnets. The
discharge from the hopper is regulated by an agitator acted upon by the
roller or other part of machinery. The particles of steel and iron which
adhere to the magnets are brushed off and deposited into a box by a revolving
brush or other suitable agent. It is evident that this improved machinery
may be used to separate small particles of iron or steel from any other metals
or materials.
And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to describe the means pursued by me, reference.
being had to the figures and letters marked on the, accompanying Sheet of
Drawings.
Fig. 1 is a transverse section; Fig. 2 is a front elevation; and Fig. 3, a
plan of my improved machinery. a, a, aro two standards, to which are
fixed the bearings for the axles of the magnet roller band brush roller c; the
circumference of the roller b is furnished with the magnets 6', bolted to little
angle brackets which are screwed to the roller b, or connected thereto in any
other convenient manner. The magnets are arranged in a spiral line around
the roller b, as shewn by the dotted lines in Fig. 3, and they revolvo within'
the trough d, above one end of which is the hopper e; the bottom of the
hopper is placed above the wheel f, which has ten or other convenient number
of chambers, and which is turned round one-tenth or other part of a revo-
lution for each revolution of the roller 6 by the stud acting on pins pro-
jecting from the wheel f. At the other end of the roller 6 is a spout g,
beneath which is placed a vessel to receive the cleansed filings, borings, or
turnings. The requisite rotary motion is communicated to the rollers 6 and c
by a strap passing round the pulley c¹ on the axle of the roller c, to which is
fixed a pinion &, gearing into a wheel 6, fixed to the axle of the roller b. The
mode of operation is as follows:-The mixed filings, borings, or turnings to
be operated upon are fed into the hopper e, and the driving strap is then put
on the pulley c; a slow rotary motion is thus given to the roller b, which, in
revolving, gives motion to the wheel f, thereby bringing the mixed filings,
borings, or turnings from the hopper in small quantities into the trough d,

page_text: where they are acted upon by the magnets b, which being placed so as to
form a spiral line round the roller, gradually traverse the filings, borings, or
turnings to the other end of the trough, where they drop through the
spout into a receptacle placed beneath it to receive them. The small
particles of iron and steel mixed with the brass filings, borings, or turnings
adhere to the magnets and are struck off them by the revolving brush c into
the box h, placed under the brush. It is evident that this improved
machinery may be used to separate small particles of iron or steel from any
other metals or materials.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim the general arrangement and
combination of the machinery shewn and described for separating small
particles of iron and steel from any other metals or materials, and particularly
the placing of the magnets in a spiral line on the circumference of a roller,
together with the self-acting feeding and delivering apparatus, whereby the
supply and discharge are self-regulating.
In witness whereof, I, the said John Parkinson, have hereunto set my
hand and seal, this Twentieth day of October, in the year of our Lord
One thousand eight hundred and sixty.
Witness,
H. B. BARLOW,
Manchester.
