JAMES POWLES WEST, Engineer, 82 Campbell Road Bow, London, E. do hereby
declare the nature of my invention for REMOVING DUST AND REFUSE FROM CHAFF,
GRAIN SEEDS, AND LIKE MATERIALS, to be as follows :-
For this purpose I employ a Valve Box with hopper, made of any suitable material,
and also fitted with various, valves slides and shelves arranged as may be required,
attached to which is a fan or blower or such like arrangement for the purpose of.
exhausting and extracting the dust and refuse from Chaff, Corn, and all kinds of
grains and seeds, and such like matter as may be desired.
I also employ a series of seives in motion for the purpose of sizing the Chaff Corn,
and all kinds of grains and sceds after the same has passed through the Valve Box.
Dated this 10th day of April 1888.

Chaff, Grain, Seeds, and like Materials.
JAMES POWLES WEST Engineer 82 Campbell Rond, Bow London E. I do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR REMOVING
DUST & REFUSE FROM CHAFF, GRAIN, SEEDS, AND LIKE MATERIALS and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention and improvement relates to an apparatus whereby I am enabled to
exhaust, extract and separate the dust refuse, and other pernicious matter from Chaff,
Corn, and all kinds of grain and seeds, without extracting any of the valueable
matter whatsoever.
For this purpose I employ and use a Fan, blower, exhaustor, or any such like
arrangement, the same being fixed and enclosed inside a Valve Box which also forms
a Vaccum Chamber made of wood or any other suitable material, and fitted up with
various adjustable balanced air valves, swing valves, slides, and shelves arranged as
may be desired: The said Fan, blower, or exhauster, being fixed inside the Valve
Box or Vaccum Chamber at the one end; and made perfectly tight and secure, so that
all the dust and refuse is drawn through same; and at the other end are attached
one or more adjustable balanced swing valves, slides and shelves, and for this purpose
I fix or attach to the Valve Box or Vaccum Chamber an hollow oblong box and
hopper, which is also for the purpose of receiving the chaff, corn, and all kinds of
grain and seeds. I also fix at or near the centre of the top of Valve Box or Vaccum
Chamber an adjustable balanced air valve by which means a certain quantity of air
may be admitted if required. I may also mention that this adjustable balanced air
valve acts automatically so that should the Fan, blower or exhauster after being
regulated create a greater vaccum than required this balanced air valve will admit air,
and thus prevent the heavier material coming away with the lighter dust and refuse.
The Chaff, Corn, and all kinds of grain & seeds passes or drops right through the
said oblong box and hopper, the adjustable balanced swing valves which are flat and
hung at a slight angle of inclination receiving same, and thereby as it passes from
one valve to another causes it to glide through in a thin film instead of in a bulk,
and whilst thus passing through this oblong box the exhauster so extracts the dust
and refuse through the vaccum chamber and thence through the Fan, blower, or
oxbauster and then it is passed out through the outlet into a dust room or into the
open air as may be desired, and also should the chaff, corn, grain or seeds at any
time come down in an extra quantity the swing valves are so adjusted with the
balance weights that they immediately relieve themselves, by the extra weight coming
upon them, and so opening and allowing the chaff corn & grain to go straight
through, and then return to their norinal position and thus preventing any choking
taking place. At the bottom end of oblong box and hopper are a series of perforated
holes, attached to which is a slide with duplicate perforated holes same being regulated
by a thumb screw, this said slido being for the purpose of admitting more air into
the vaccum chamber if required; at the box end and inside the Vaccum Chamber
is also attached a flat valve or baffle plate, same may be adjusted as desired by a
set screw and qudrant which are attached outside, to any angle of inclination
according to the subject matter that is being treated.

page_text: In the case of chaff cleaning I attach the Box immediately underneath the chaff
cutting machine so that the chaff falls direct from the knives as it is being cut and
at once into the hopper. The upper part of the knives of the chaff cutter are also
enclosed and attached direct to the Vaccum Chamber by means of pipes or any such
like arrangement, so that the dust and refuse is also extracted and exhausted direct
from the knives of the chaff cutter both above and below same and 1 can attach one or
more pipes to a box above the knives and instead of connecting same to the vaccum
chamber connect and carry same direct into an upright pipe into the open air, the
length of pipe thus acting as an exhauster.
It is obvious by the apparatus thus described that I am enabled to effectually
remove and extract the dust and refuse from Chaff, Corn, grain, and all kinds of
seeds without extracting any valueable matter whatsoever.
In order that my invention and improvement may be more fully and clearly under-
stood I will herewith aided by the accompanying drawings describe same.
