COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Removing or
Separating Metals from Seeds and other Granular Substances,
and the like, or from Fibrous Matter.
I, WILLIAM ROBERT HARRISON, of 191 St. Georges Road, Hull, in the County
of Yorks, Mechanical and Consulting Engineer, do hereby declare the nature of

page_text: this Invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to provide an improved method of, and apparatus
for separating scraps or particles of iron, steel, or the like from seeds or other
granular substances, or from fibrous or other matters.
DESCRIPTION OF DRAWINGS.
Fig 1 is a vertical elevation of my improved contrivance for extracting particles
of metal from seeds or other granular substances, or from fibrous matter.
Fig 2 is a plan view of Fig 1.
For the purpose of my invention, I employ any suitable type of band or other
conveyor for conveying the seed or matter to be treated. Over this conveyor, and
placed parallel to it, but not necessarily moving in the same direction, I mount an
endless metallic band, or belt of any suitable material, carried by rollers, to which
I impart motion by means of suitable gearing, this metallic band, may be composed
either of a thin continuous plate, or of a succession or combination of plates, links,
or chains, or a belt of canvas, indiarubber, or the like may be employed if desired.
I connect this metallic band or the like, with a dynamo or other electrical.
generator, preferably by means of a horseshoe or other suitable form of magnet, or
magnets, or the like supported in any suitable manner, such magnet or the like,
being placed preferably within the continuous band, that is, the lower half of the
band as it revolves, interposes between the said magnet or the like, and the sub-
stance to be operated upon and where necessary, I insulate the metallic band or
belt by means of non-conducting rollers, or non-conducting bearings, or by other
suitable means.
I arrange the bearings carrying this metallic band or belt, in such a manner,
that I can bring the underside of such belt, by adjustment, into close proximity
with the top side of the conveyor, and I further place it in such a position, that
one end roller of it extends beyond the said conveyor. Against this end roller of
the metallic band, I place a non-conducting scraper, scrubber, or brusher, and
immediately under this, I place a trough or spout for conveying away the pieces of
metal which have been attracted and have adhered to the metallic or other belt
or band.
A, A, A, represents the terminal end of an ordinary band conveyor, B being the
terminal drum over which the band passes. CC are supporting rollers for the
conveyor band, D being the supporting frame for same; E E is an endless band
of any suitable metal or material through which the magnetic action can pass,
sheet steel, charcoal-iron, or even canvas, indiarubber, or the like, and is carried
by the rollers FF, which are supported by brackets G G, each bracket having a
means of adjustment for raising or lowering on the frame H, by means of bolts,
pins, or the like J J, or any other suitable means of adjustment and support.
K is a magnet of horse shoe or any other suitable shape or type, working in
conjunction with a dynamo or other electrical generator. A brusher or scrubber
L, is employed for removing any particles of metal which might adhere to the end-
less band or the like.
M is a baffle plate, employed for catching the pieces of iron, steel, or the like,
which have been extracted from the material operated upon, and have then being
carried out of the range of magnetic action by means of the endless band E.
N is a spout or trough, into which the aforesaid particles fall, after sliding down
the baffle plate M.
O and are respectively the hopper, and spout into which the material falls
after any pieces of iron, steel or the like have being separated or extracted from
it is the pulley for driving the endless band E, and R is the pulley which
drives the band conveyor A. The action is as follows:-The material to be treated
is placed upon the conveyor A, and by it is brought, preferably at its terminal
end, underneath the apparatus for extracting the metal or the like particles, and
as soon as it arrives within the range of the magnetic action induced by the horse-

page_text: shoe or other magnet, any pieces or particles of iron, or steel which it may contain
are drawn towards the face of such magnet, but on account of the endless band E,
being interposed between the magnet or the like and the substance being operated
upon such pieces or particles are attracted to the said endless band, and are moved
along by it until they get beyond the action of the magnetic lines, when they drop
by gravity on to the sloping baffle plate M, which in turn deposits them into the
collecting trough N or into any other convenient receptacle, the sweeper or brusher
L, removing any small particles which may be left adhering to the endless band E
and dropping them on to the same sloping baffle plate M.
The rollers FF, which carry the endless band E, being adjustable admit of the
space between the endless band and the conveyor belt being adjusted to suit the
class of materials operated upon, and the nature of the metals to be extracted.
This apparatus is also applicable to any other suitable type of conveyor on which
the substances to be treated can be spread out and passed along. If desired, in
place of having an endless band and interposing belt, a moving plate or disc or the
like, may be employed whether with a reciprocating or other suitable motion.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is.
1. An apparatus for extracting or separating particles or pieces of metal from
seeds or other granular substances or fibrous matters or the like consisting of a
band or belt of any suitable metal or material passing over rollers, a magnet or
magnets for attracting the particles of metal such magnet or magnets being pre-
ferably electro magnets connected to a dynamo or other suitable electrical generator
the apparatus being placed over or in close proximity to a suitable conveyor
carrying the substance to be operated upon in the manner and for the purposes
substantially as shown and described.
2. Energizing an endless band placed in close proximity to the substance to
be operated upon by means of an electro or other magnet for attracting the metal
particles in the manner and for the purposes substantially as shown and described.
3. The placing of a moving medium whether revolving or reciprocating between
the face or faces of an electro or other magnet or the like and the material to be
operated upon whereby the pieces of iron, steel or the like are attracted out of it
and to the interposing medium which by its motion carries them out of the range
of the magnetic action and so deposits them clear of or away from the materiai
from which they have being extracted in the manner and for the purposes
substantially as shown and described.
