I, ALEXANDER HENRY REED, of Suffolk House, Laurence Pountney Hill, Cannon
Street, in the County of Middlesex, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to a machine which is intended principally for concentrating
magnetic iron ore in an economical manner, but which can also be used for separating
iron filings from non-magnetic matter The peculiar and novel construction of the
machine is set forth in the following specification and claims and illustrated in the
accompanying drawing in which
Fig 1 is a plan view, some portion being broken away to expose the parts below.
Fig 2 is a vertical section in the plane ax, fig 1, looking in the direction of the
arrow opposite to that line.
Fig. 3 is a similar section in the plane y y, fig. 1, looking in the direction of the
arrow opposite to that line.

In this drawing the letter A designates a frame which forms the bearings for four
rollers B B, B B¹. The rollers B B support the primary endless apron D, and the
rollers B B support the secondary endless apron C which runs transversely to the
apron D
a hopper placed over the primary apron D In proximity to
the secondary apron Care placed one or more magnetized plates F. These plates are
made preferably of hardened steel, and by placing upon them one or more magnets G,
they become magnetized. The magnets G may be permanent magnets or electro-
magnets. The plates F are secured to traverses E¹ which are connected by screws a a
to the frame A, so that by means of said screws the plates F can be raised or lowered.
A hopper H is placed in suitable relative position to the secondary apron C fig. 8,

provided, one for the concentrated ore or iron particles, and the other for the gangue
or refuse A belt N which extends round pulleys L M is made to impart motion to
the aprons CD Said belt passes over guide rollers 0 0, figs. 1 and 3.
The machine operates as follows: the ore or the material to be treated is crushed
or pulverized and fed to the primary apron D through the hopper E so as to form
a thin layer on said apron. As the apron is moved in the direction of the arrow
thereon in figs 1 and 2, the layer of pulverized ore passes slowly beneath the
magnetized plates F, and the iron contained in said layer being attracted hy said
plates is caused to adhere to the secondary apron C which moves in the direction of
the arrows shown thereon in figs. 1 and 3 As this secondary apron moves along,
the particles of iron adhering to it are carried over the hopper H and they drop down
through the hopper into the receptacle J, being separated from the apron either by
their inherent gravity or by the action of the scraper I The non-magnetic particles
in the layer formed on the primary apron D are dropped into the receptacle K. The
machine can be used for concentrating iron ores of different kinds, and it has been
found very useful in treating magnetic iron ore containing phosphorus or titanium.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim 18.
1. The combination with a primary apron, of a secondary apron made to operate
transversely to the primary apron, a magnetized plate secured in proximity to said
secondary apron so as to draw the iron particles to said secondary apron, and suitable
driving mechanism for actuating the apions, substantially as set forth.
2. The combination with a primary apron and a secondary apron made to operate
transversely to the primary apron of a magnetized plate secured in proximity to said
secondary apron so as to draw the iron particles to said secondary apron, suitable
driving mechanism for actuating the aprons, and a scraper or brush made to act on
said secondary apron, substantially as set forth.
3 The combination with a primary apron, of a secondary apron made to operate
transversely to the primary apron, a magnetized plate secured in proximity to said
secondary apron so as to draw the iron particles to said secondary apron, and means
for adjusting the magnetized plate in relation to the secondary apron, substantially
as set forth.
