PROVISIONAL SPECIFICATION.
: An Improved Combined Grain Cleaner and Magnetic Separator.
JAMES POWLES WEST Engineer 156 Devon's Road Bow London E. do hereby
declare the nature of this invention to be as follows:-
For this improvement I employ an enclosed casing or box: on the top of which
is placed a regulating inlet hopper for admitting the grain & seed, fixed in the
bottom of the said inlet hopper is an agitator revolving in same to prevent the
grain & seed from choking.
I suspend in the enclosed casing or box a separator fitted with various sized
seives for grading and sizing the grain and seed, and also for separating the rough
material, such as sticks, straws, stones string &c.: the said separator receives its
joggling motion by either a cam or crank, and the incline of this said separator is
regulated by means of an adjusting screw. The grain and seed after leaving the
separator drops on to a series of slides or shutes, and passes down arranged divisions,
and out of its various openings at the bottom of the said enclosed casing or box.
I also attach in the above mentioned slides or shutes: which are adjusted in
the said enclosed casing or box: a series of compound magnets, which extracts all
the pieces of steel, iron, nails &c. from the grain & seed as they pass over the
compound magnets. An exhaust fan is also attached inside the above said enclosed
casing or box, this said exhaust fan extracts and removes all the dust, and lighter
material from the grain & seed during its passage over the separator, slides or
shutes, from the inlet of the grain and seed into the enclosed casing or box to the
outlets of the said enclosed casing or box. A perforated slide valve is attached to
one of the sides of the said casing or box, for the further admission of air when
required. The above said exhaust fan, and separator are driven by power or by
hand by means of an arrangement of gearing or pullies to obtain the speed
required.

An Improved Combined Grain Cleaner and Magnetic Separator.
JAMES POWLES WEST Engineer 156 Devon's Road Bow London E. 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:-
For this improvement I enclose in an oblong box or casing an exhaust fan, a
separator with sizing sieves, and a series of combined compound magnets: the said
box or casing having an inlet for the uncleaned grain or seed, with outlets for the
The inlet
separated and cleaned grain or seed, and also for the refuse from same.
hopper for the uncleaned grain or seed is attached on the top of the said box or
casing, and is fitted with a revolving roller or agitator driven by pullies from one
of the hereinafter mentioned spindles so as to prevent the grain or seed from
choking and the inlet of the grain or seed to the reciprocating separator being
.

page_text: regulated by a quadrant valve. The separator with sizing sieves is hung up in the
said box or casing by flat steel or ash springs, receiving its recipricating motion by
a connecting rod from an eccentric or cam fixed on a spindle revolving in bearings
fitted up outside the said box or casing.
The said separator is fitted with a top sieve of a coarse mesh for separating and
throwing off the rough refuse from the grain or seed, such as sticks, straws, stones,
and such like refuse; the lower sieve being of a fine mesh, through which all the
heavy grit and dirt is separated, and falls on to the bottom of the said separator,
and is thence delivered outside the said box or casing, by a spout coming through
the side as shewn on the accompanying drawings, Sheet 1. Fig. 1, and lettered. A:
the rough refuse is thrown off the end of the said separator at the outlet in said
box or casing, as shewn on the accompanying drawings, Sheet 2, Fig. 3, and.
lettered e, e, and thence delivered into a receptacle provided for same and
lettered F: the separated grain or seed after leaving the separator falls on to
inclined planes or shutes fitted up inside the said box or casing as shewn in the
accompanying drawings Sheet 2, Fig. 3, and lettered G, and thence passes over the
face of the combined compound magnets, the said combined compound magnets
being fixed to one of the inclined planes or shutes, the face of both of same being
true and flush one with another as shewn in the accompanying drawings Sheet 2,
Fig. 3, and lettered H, and the grain or seed in passing over the face of the said
combined compound magnets, are thus freed from all particles of steel, nails, and
such like metallic substances by the same being attracted and held by the magnetic
power of the said combined compound magnets: a sliding door being made in one
side of the said box or casing as shewn in the accompanying drawings Sheet 1,
Fig. 1, and lettered B, for the purpose of clearing and freeing the said combined
compound magnets of the metallic substances adhering thereto.
:
The exhaust fan is fitted up and attached inside the said enclosed box or casing
as shewn in the accompanying drawings, Sheet 2, Fig. 3, and lettered I, and the
said exhaust fan extracts and removes all the dust and lighter material from the
grain and seed, which is created by the action of the separator, and also extracts
what remains in the separated grain or seed as it passes to and through the outlet,
lettered K a regulating perforated slide is fitted to the said enclosed box or casing
at top end of the same, as shewn on the accompanying drawings, Sheet 2 Fig. 3,
and lettered J and by opening or closing this said regulating perforated slide the
admission of air to the exhaust fan may be regulated as required. The said
exhaust fan is driven by a pulley in the ordinary manner, attached and fixed on the
fan spindle, and the said fan spindle is connected to the eccentric or cam spindle by
pullies for driving same to speed required. Should the same at any time be
required to be driven by hand power, geared wheels and pinions may be used to
obtain the speeds required.
When the grain or seed is required to be sized or graded as well as being cleaned,
various sized sieves may be fixed in the separator for that purpose to suit the grain
or seed that is to be thus treated, and divisions placed on the inclined planes or
shutes to receive the different sized grain or seed.
In order that my invention may be more fully and clearly understood, I will
herewith aided by the accompanying drawings describe the same.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
The combination of the exhaust fan, separator, and combined compound magnets,
enclosed in a box or casing.
