PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying Flake Oatmeal and such
like Substance.
I, LEWIS SCOTT, of Omagh, County Tyrone, Ireland, Gentleman, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to improvements in apparatus for drying flako
oatmeal and such like substance in a simple, expeditious and efficient manner.
In carrying out my invention I propose to construct a suitable chamber in which
are arranged a series of rectangular trays so placed that each alternate plate
assumes longitudinally an inclined plane to its neighbours thus forming in
appearance a zig-zag arrangement.
The chamber thus fitted is hung in suitable framework and receives a lateral
oscillation, or to and fro movement through the agency of a horizontal shaft
provided with suitable cams for the purpose.
Over the framework is arranged a suitablo fan for the purpose of drawing
heated air through the chamber and thus through the series of rectangular
plates.
"
As thus constructed the action of my said invention is briefly as follows:-
The oatmeal or other substance to be dried is received from a pair of ordinary
rollers on to the first or upper rectangular plate, thence on to the second and
so on passing from one plate to the other until it reaches the last in the series
from which it falls in a dry and wholesome condition into a suitable hopper or
bench.
To facilitate the passage of the heated current through the chamber the plates
may be suitably perforated.
It is obvious that the speed at which the substances passes over the series of
plates may be adjusted at pleasure by altering the angle of each respective
plate.
Likewise the lateral oscillating movement may be adjusted by altering the throe
of the cams on the rotating borizontal shaft.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Drying Flake Oatmeal and such
like Substance.
I, LEWIS SCOTT of Omagh County Tyrone, Ireland, Gentleman 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 reference to improvements in apparatus for drying flake
oatmeal, and such like substance, in a simple expeditious, and efficient manner. .

page_text: In carrying out my invention I propose to construct a suitable chamber in which
are arranged a series of rectangular trays, so placed that each alternate plate
assumes longitudinally an inclined plane to its neighbours, thus forming in
appearance a zigzag arrangement.
The trays are fixed to a suitable framework which is suspended from the top of
the chamber by means of vertical springs, and receives a lateral oscillation or
to & fro movement through the agency of a horizontal shaft provided with suitable
cams, or eccentrics for the purpose, such eccentrics being connected with the
framework of the trays.
Over the framework is arranged a suitable fan for the purpose of drawing
heated air through the chamber, and thus through the series of rectangular trays
or plates.
The oatmeal or other substance to be dried is received from a pair of ordinary
rollers, on to the first or upper rectangular plate or tray, thence on to the second,
and so on passing from one plate to the other until it reaches the last in the series,
from which it falls in a dry, and wholesome condition, into a suitable hopper or
bench.
To facilitate the passage of the heated current of air through the chamber, the
plates or trays may be suitably perforated.
It is obvious that the speed at which the substances pass over the series of
plates, or trays may be adjusted at pleasure by altering the angle of each respective
plate or tray.
Likewise the lateral oscillating movement may be adjusted by altering the throw
of the cams or eccentrics on the rotating horizontal shaft.
In order that my invention may be fully understood, I will describe the same
with reference to the accompanying drawings in which
Figure 1 represents a side elevation of my improved apparatus partly in section,
having the outside caseing removed.
Figure 2 represents a front elevation of my improved apparatus partly in section
having the front caseing removed, and
Figure 3 represents a plan of my improved apparatus.
Similar letters refer to similar parts in each figure.
The rectangular chamber is represented at A, this chamber is composed of
galvanized, or ordinary sheet iron or steel, and connected together at the
corners, and the top, and bottom by means of the angle iron B or by suitable
castings.
The frames C to which the perforated trays or plates D are secured, are
suspended from the cross bars E, by the springs F, these springs being secured
at the top to the cross bars E and at the bottom to the frames C.
The framework C receives the lateral oscillation through the agency of the
horizontal shaft G provided with the eccentrics H and connecting rod S which is
secured at one end to the framework C. The suction fan K draws the hot air
through the perforations in the trays D and thus through the substance being
passed over them.
The substance to be dried is fed into the hopper L, and from thence passes
down to the top tray, or plate M, along which it travels until reaching the
opening N, through which it falls onto the second tray, or plate, and so on until it
arrives at the bottom plate or tray O, from whence it is discharged into the delivery
hopper P.
The heated air is supplied through the pipe Q, and is evenly distributed by means
of the inverted fixed plate R.
The substance being operated upon is caused to travel over the series
of trays, at the same time being subjected to a suitable heat in such a
manner that by the time it reaches the bottom or delivery tray O, it is
perfectly dry.

page_text: Having now particularly described, and ascertained the nature of my said iuven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1. An apparatus for drying flake oatmeal or other like substances, constructed in.
the manner described, and represented in the accompanying drawings.
Dated this 24th day of April 1896.
