Improvements in Apparatus for Separating Metallic Substances
from Cut Chaff or other Materials.
I, SAMUEL EDWARDS, of The Glen, Ladywell, Eccles in the County of:
Lancaster, Engineer, do hereby declare the nature of my invention to be as
follows:-
My invention relates to improvements in apparatus for separating metallic
substances from cut chaff more particularly, but it may also be used for other
materials if desired.
It is found that in most cases the primary cause of the formation of the hard
balls found in the stomachs of horses and cattle, is some small piece of metal, round
which the other substance forms, and it is the object of my invention to arrest and
eliminate these particles of metal.
I therefore construct a framework of wood or other material, in the form of a
hopper into which the cut chaff will fall from the chaff cutter, dropping upon one
of the sides which is inclined.
Upon this inclined side of the hopper I arrange a vertically travelling series of
magnets fixed upon an endless chain which carries the magnets down the incline,
through an opening and up the outside.
In a convenient position outside I fix a revolving brush which acts against the
surface of each magnet as it passes upwards, thus any particles of metal caught by
the magnets in the hopper are carried to the outside and are there swept off by the
brush into a receptacle.
To render the apparatus more effective and to catch any bits of metal that may
have escaped the first named magnets, I fix at or near the bottom of the hopper
frame a rotary magnet upon which all such escaped particles must fall and be
caught and are scraped or brushed off as they are carried round.
The apparatus with its various motions may be driven by any suitable motive
power or by hand.

1, SAMUEL EDWARDS of The Glen, Ladywell, Eccles, in the County of
Lancaster, Engineer do hereby declare the nature of this invention and in what
manner the same has to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention relates to improvements in apparatus for separating metallic

page_text: substances from "cut chaff" more particularly, but it may be also adapted for use
in separating particles of metal from other substances.
In relation to the cleansing of chaff I may premise that it is found in most cases,
the primary cause of the formation of the hard balls found in the stomachs of
horses and cattle is some small piece of metal eaten with the food round which
the other substance forms, and it is the object of my invention to arrest and
eliminate these metallic particles from the food before it is eaten.
The apparatus constructed as I prefer is shown in the annexed drawings in
which
Fig. 1, is a side elevation showing the interior mechanism.
Fig. 2, is a front end elevation of same.
I construct a suitable framework preferably of wood A, having in its upper part
a hopper B, to receive the chaff as it falls from the chaff cutter.
In the body of the framework and passing below the hopper B, I fix an inclined
endless machine chain traveller, revolving upon two sets of chain wheels C, C²,
(or in some cases an endless band of cheaper construction may be used) held in
suitable bearings resting upon diagonal bearers D.
Across the chain are wooden slats or boards E, and upon the boards are fixed a
series of magnets F; an inclined table G, being placed under the upper series of
magnets to catch the chaff and conduct it downwards.
To cleanse the magnets from any pieces of metal caught by then and attaching
thereto, I fix a revolving brush H, in the upper part of the frame, which, acting
upon each passing magnet brushes the pieces of metal off into the chamber I, or
into a removable receptacle placed in that position.
To render the apparatus more effective and to catch any bits of metal that may
have escaped the first named magnets, I fix underneath the lower end of the
chain traveller a revolving drum J, provided with a series of magnets upon which
the chaff and any escaped particles of metal must fall on their way to the outlet K,
and by which they are caught, and from which they are scraped by a scraper L, or
its equivalent. M is the driving pulley, N is the belt driving the rotary brush H,
O is the cross belt transmitting power from the shaft of brush H, to the drum J.
The arrows indicate the lines of motion of any of the parts to which they are
adjacent.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that what I
claim, is :-
1. The apparatus for separating metallic substances from cut chaff or other
materials, as hereinbefore described and shown.
2. An apparatus for separating metallic substances from cut chaff, having a
travelling band of magnets upon which the chaff falls, a revolving brush acting
upon the magnets to cleanse same, and a revolving drum provided with magnets
situated beneath the travelling band, to intercept and catch metallic particles
escaping from the upper magnets, constructed substantially as herein before
described and shown.
