VISIONAL SPECIFI
Improvements in or relating to Whizzers or Devices for Drying or
Purifying Wheat Grain.
I, FRANK THOMPSTONE, of Dane Corn Mills, Bosley, near Macclesfield, in the
County of Chester, Miller, do hereby declare the nature of this invention to be
as follows:-
In the ordinary vertical whizzer the grain is fed in at the bottom and the
oblique beaters whirling round in the inside gradually carry the grain up to
the exit spout at the top. In the meantime the water and any dirt there may be
among it escape through the perforated casing.
Now by my invention I apply a blast of air to these whizzers, whereby the
drying and purifying properties are very greatly increased and improved, and
the air currents can be regulated by valves according to the dryness of wheat
required. I prefer to place a fan both at the bottom and at the top and place a
guard or projecting sleeve at the top and a cone guard fixed to the beaters near the
bottom to prevent grain coming in contact with the fans. The inlets to the fans or
the outlets from the fans as the care may be, preferably the former, are provided with
valves for regulating the amount of air supply. The air can be hot or cold. In most
instances it will be cold. By means of my invention the grain can be kept in
the whizzer a very much shorter time and the beaters consequently placed at
a steeper angle, or the whizzer shortened in its length and thus a given size of
whizzer will treat successfully a very much larger amount of grain or dry the
same amount of grain to a very much greater extent in the case of my whizzer
than in the case of an ordinary one.
I have described the preferred way of carrying my invention into effect, but
I wish it to be understood that, I do not restrict myself to the details described
as these can be altered without departing from the nature of the invention.
Thus the fans may be arranged in a different manner, or separate fans may be
used delivering air to one or more whizzers by pipes.

Improvements in or relating to Whizzers or Devices for Drying or
Purifying Wheat Grain.
I, FRANK THOMPSTONE, of Dane Corn Mills, Bosley near Macclesfield, in the
County of Chester, Miller, do hereby declare the nature of this invention and in
what manner the same is to he performed, to be particularly described and a-cer-
tained in and by the following statement:-
E
hin the min in faol in at the bottom and

page_text: oblique beaters whirling round in the inside of the perforated casing gradually
carry the grain up to the exit spout at the top. In the meantime the water and
any dirt there may be among it escape through the perforated casing.
Now by my invention I apply a blast of air to these whizzers, whereby the
drying and purifying properties are very greatly increased and improved, and
the air currents can be regulated by valves according to the dryness of wheat
required.
For the better understanding of my invention I append the accompanying
drawings,
Figure 1 being a sectional elevation of the whizzer and
Figure 2 front elevation of bottom half of whizzer.
In these A is a vertical shaft in bearings B and C. This carries the frame-
work of beaters D D by means of brackets E E. F and I are two fans one above
and the other below. One fan only need be used, but I prefer two as giving a
more equable result. Above the lower fan I place cones G to prevent grain
falling into the fan when machine is stopped with feed on. In the lower cone
there are holes g but in the one above there are no holes. II is the perforated
wire casing. I a sleeve depending into the centre so as to induce the air from
the top fan. J is the delivery spout and K the frame-work of the machine.
L is a further protection for the upper fan so as to prevent the upwardly rising
grain being dashed into it. M feed spout. It will be noticed that the size of
the upper fan is much larger than the lower. This I find to act best in practice.
The inlets to the fans are provided with valves or shutters not shown in the
drawings, but of any convenient form for regulating the amount of air supply.
By means of my invention the grain can be kept in the whizzer a much shorter
time and the beaters consequently placed at a steeper angle or the whizzer
shortened of its length and thus a given size of whizzer will treat success-
fully a much larger amount of grain or dry the same amount of grain
to a much greater extent in the case of my whizzer than in the case of
an ordinary one. In thus describing my invention I do not bind myself to this
exact form of wltizzer. The fans may be arranged in any desired nanner;
indeed they can even draw out from the outside of the perforated wire instead
of driving the air in, or separate fans may be used delivering air to one or more
whizzers by means of pipes or of sucking air out from an outside casing sur-
rounding the wire casing. I do not however advise the second plan, as it involves
an outside air-tight casing, and is thus very undesirable.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The improvement in or relating to whizzers or devices for drying wheat
and other grain, which consists in the combination with beaters rotated in a
perforated wire casing of a device for causing a strong regulated current of air
through the machine substantially as described.
2. The general arrangement of whizzer with fans or any propelling or inducing
mechanism, substantially as described.
