COMPLETE SPECIFICATION.
An Improved Kiln for Drying Oats, Malt, Indian Corn, and other
similar Material.
I, JAMES WALWORTH, of Longfield Villa 130 Legrams Lane, Bradford in the
County of York, 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 :-
Having found by experience in employing my patent grain dryer (No. 5956
of 1889) for oats, Indian corn, malt, or any material which it is necessary to subject
to an intense heat, that the perforated metal or wire gauze towards the top of the
cylinder corrodes, and becomes useless, thus requiring to be frequently renewed.
To obviate this I form the outer cylinder, or both outer and inner cylinder of
perforated tiles, or I'may employ part tiles in combination with wire gauze, or
perforated sheet metal.
To carry out my invention 1 form the framework of two vertical cylinders, one
within the other, similar to those mentioned in my Specification No. 5956 of 1889.
but in place of the angular rings, or flanges I employ rings, or ribs having
rectangular grooves or gutters formed round the top, and under side, these rings or
ribs are secured to vertical rods, at a suitable distance apart. I make up the space
between each rib, with perforated tile segments, which are formed to fit into the
rectangular grooves or gutters. The oats, or other similar material passes down
between the two cylinders, and is dried in its descent by means of a current of hot
air being blown through it.
In order that my invention may be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which
Fig. 1 represents a front elevation partly in section, of the upper part of
the kiln.
Fig. 2 represents a sectional plan of the kiln.
Fig. 3 represents a cross section of one of the tile segments.
Fig. 4 represents a transverse section of part of one of the internal ribs or
rings.
Fig. 5 represents a transverse section of part of one of the external ribs, or
rings.
Fig. 6 represents a frout elevation of part of a tile segment.
Fig. 7 represents a transverse section of part of an internal ring, or rib for
forming the junction between the wire gauze or perforated sheet metal, and the
tiles, and
'
Fig. 8 represents a transverse section of part of an external ring or rib, for
forming the junction between the wire gauze, or perforated sheet metal and the
tiles.
Similar letters refer to similar parts in each figure.
The interual cylinder is represented at A, and the external cylinder at B, such
cylinders being formed of perforated tile segments C, and D respectively, which
tiles are held in position by means of the grooves or gutters E formed round the
top and bottom of the rings, or ribs F which may be formed in two or more
segments to complete a circle.
The lugs G formed ou the rings or ribs F are fixed to the vertical rods K which
are secured to, and suspended from the plate L. The ribs F are arranged at a
suitable distance apart in order to receive the perforated tile segments C, and D
into the grooves, or gutters E.
In employing perforated sheet metal or wire gauze in combination with perforated

page_text: tiles, I form the junction rings or ribs 0 (shown in Figures 7, and 8) with rectangular
grooves or gutters M for receiving the tiles, and the flanges N to which I secure the
wire gauze, or perforated sheet metal P.
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. In vertical cylindrical drying kilns the tile segments C, and D constructed in
the manner described, and represented in the accompanying drawings.
2. In vertical cylindrical drying kilns the perforated tile segments C, and D, in
combination with the rings or ribs F, having the grooves, or gutters E, and M, and
flanges N constructed in the manner and for the purpose described and represented
in the accompanying drawings.
3. In vertical cylindrical drying kilns, employing perforated tile segments in
combination with wire gauze or perforated sheet metal.
Dated this 4th day of September 1894.
