PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Hot and Cold Air in:
Drying Machines for Wheat or Cereals or other analogous
Materials.
I, JAMES HIGGINBOTTOM of 32 Seel Street, Liverpool in the County of
Lancaster, Milling Engineer, do hereby declare the nature of this invention to be
as follows:
My invention has for its object the reduction of the cost of applying fans for the
supply of hot and cold air to drying machines, which are used for drying wheat,
cereals and the like.
In carrying out my invention, I arrange a fan in such a manner that hot air enters.
at one side of the fan and cold air at the other side. Thus one fan serves to
discharge hot and cold air.
I preferably make the fan with a diaphragm, and I make a divided discharge
orifice to the fan casing.
By these means I am enabled to provide a cold air current and a hot air current.
by the use of one fan, instead of using two fans as is ordinarily the case.
Dated this 10th day of December 1894.

Improvements in Apparatus for Supplying Hot and Cold Air in
Drying Machines for Wheat or Cereals or other analogous
Materials.
I, JAMES HIGGINBOTTOM, of 32, Seel Street, Liverpool, in the County of
Lancaster, Milling 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 has for its object the reduction in the cost of applying fans for
the supply of hot and cold air to drying machines which are used for drying
wheat, cereals and the like.
In machines for drying wheat or other grains it is usual in modern practice
to subject the wheat or other grains to be dried, firstly, to the action of a current
of hot air and secondly, to a current of cold air as is well understood by millers,
also such drying machines are provided with two distinct fans viz., one for hot
air and one for cold air.
Now by means of my invention I am enabled to provide the necessary currents
of hot and cold air simultaneously by the use of one fan only, thus reducing the
cost of applying fans to drying machines when used for drying wheat, cereals
and the like.
In carrying out my invention, I arrange a fan in such a manner that hot air

serve to discharge both hot and cold air at the same time.
The accompanying drawing shows a fan constructed according to my invention
and applied to a drying machine, such fan being divided into two portions by
means of a diaphragm A, and the fan casing and discharge orifice B I also divide
by plate C. The hot air enters at D and the cold air at E.
The streams of hot and cold air leaving the sides F1 and F' of the fan are
carried by conduits G and G' to the wheat drying machine H.
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 improved apparatus for supplying currents of hot and cold air simultaneously
to machines for drying wheat, cereals and the like, consisting of a divided fan and
fan casing arranged substantially as shown, whereby hot air is drawn in at one side
and cold air at the other, and discharged through separate orifices substantially as
described.
