I, JAMES WALWORTH of Albert Works, Lister Hills, Bradford in the County of
York, Corn 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 consists in a stationary apparatus for drying or conditioning grain,
rice, tea, crushed logwood and other similar material by means of hot air.
To carry out my invention I employ a vertical cylinder formed of perforated sheet
metal or wire gauze having a dome shaped top. I enclose this cylinder with another
perforated cylinder leaving a suitable space between the exterior of the internal
cylinder and the interior of the external cylinder for the material to be dried or
conditioned to pass or lodge until liberated. These cylinders pass from the floor of a
room to the ceiling to which they are secured, and are fixed together at the bottom
and top if necessary by means of a double ring having vertical Hanges, the two parts
of the ring being joined together by means of arms. The material to be dried is fed
in at the top by means of a suitable hopper and is distributed equally between the two
cylinders by the dome shaped top of the internal cylinder. The grain or other
thrown from side to side
material being operated upon after entering at the top
between the cylinders by means of angular flanges fixed alternatively round the
exterior of the internal cylinder, and the interior of the external cylinder, such flanges
projecting downwards. The material passing down or lodging between the two
cylinders is dried by means of hot air which is blown into, and passes through the
perforations of the internal cylinder through the material between the cylinders and
through the perforations of the external cylinder.
In order to enable my invention to be fully understood, I will proceed to describe
the same by reference to the accompanying drawings in which Fig. 1 represents a
sectional elevation of my improved apparatus for drying grain etc. Fig. 2 represents
a sectional elevation of the bottom of my improved drier showing the outlet for
Grain etc., and the inlet for hot air. Fig. 3 represents a plan of the double ring for

page_text: connecting the two cylinders together. Fig. 4 represents a plan of one of the angular
flanges for fixing round the internal cylinder. Fig. 5 represents a plan of one of the
angular flanges for fixing round the interior of the external cylinder. Fig. 6 repre-
sents a front elevation partly in section of the angular flange for fixing round the
internal cylinder and Fig. 7 represents a front elevation partly in section of the
angular flange for fixing round the internal cylinder and Fig. 7 represents a front
elevation partly in section for fixing round the interior of the external cylinder.
The internal cylinder is represented at A the dome B of which is formed of plain
sheet metal, the other part being formed of perforated sheet metal or wire gauze
secured to the angular rings or flanges Cand double rings D to the outer ring E of
which is fixed the perforated sheet metal or wire gauze forming the external cylinder L.
The angular rings or flanges C and rings D) of the internal cylinder are connected
together by means of the vertical rods F being secured to the lugs N by set screws.
The outer rings E and angular rings or flanges G are connected together in a
similar manner by means of the vertical rods H which rods pass through the floor J
to which they are secured. The material to be dried or conditioned enters the
apparatus at K and is equally distributed between the cylinders by the dome B, and
is then thrown from the interior of the cylinder L to the exterior of the cylinder A
and vice versa during its traverse to the bottom by means of the angular rings or
flanges and G where it is divided and liberated at two sides as shown in Fig. 2.
The material is dried or conditioned during its traverse from top to bottom of the
apparatus and whilst lodging therein by means of a current of hot air forced
through the pipe M and into the cylinder A, after leaving which it passes through
the perforations into the grain and through the perforations of the external
cylinder L.

:
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 :-
I. An apparatus for drying or conditioning grain tea, rice, crushed log-wood and
other similar material constructed in the manner described and represented in the
accompanying drawings.
II. In an apparatus for drying or conditioning grain tea, rice, crushed logwood
and other similar material, the vertical cylinders A and L formed of perforated sheet
metal or wire gauze as described and represented in the accompanying drawings.
III. In an apparatus for drying or conditioning grain, tea, rice, crushed logwood
and other similar material the vertical cylinders A and L in combination with the
angular rings or flanges C and G and the double rings D as described and repre-
sented in the accompanying drawings.
