PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying Minerals, Brewers' Grains,
or other Materials.
We RICHARD MORRIS of Beechfield Doncaster in the County of York Engineer
and JAMES WOOD of West Stockwith in the County of Nottingham Engineer do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide an apparatus which will efficiently and
continuously effect the drying of materials fed thereinto and expel them as the drying
is completed. According to this invention we mount on brickwork or other suitable
support a long cylinder which may be constructed of boiler plate or other suitable
material. Lengthwise through it passes a shaft provided with means for imparting
rotary motion thereto. Upon this shaft inside the cylinder are mounted blades
forming the segments of a helix or screw with spaces between the segments. They
are attached to the shaft by arms so as to leave a space also between the segments
and the shaft. These arms and segments are of such shape that as they revolve they
pass forward the material towards the outlet and at the same time lift and turn the
material.
The spaces between the segments allow the material to remain a proper time in
the cylinder for efficient drying. The heat which is applied to the cylinder for
drying may be either applied internally or externally or both for instance, we may
use an ordinary fire underneath the cylinder with a flue extending throughout any
portion of its length or circumference, or we may use a jacket for steam or hot
water. In cases where we introduce hot air into the cylinder we may effect the
heating of the air prior to its admission by causing it to pass through a supplemental
casing surrounding or partly surrounding the cylinder and preferably arranged so
that the inlet from this air casing to the cylinder is at the discharge end of the said
cylinder. The shaft may be made hollow so as to admit of water being admitted
thereto to prevent it from getting too hot and damaging the bearings. The arms or
segments or both may also be made hollow for the water to circulate through
them also.

We RICHARD MORRIS of Beechfield Doncaster in the County of York Engineer
and JAMES WOOD of West Stockwith in the County of Nottingham 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:
The object of this invention is to provide an apparatus which will efficiently and
continuously effect the drying of materials fed thereinto and expel them as the drying
is completed. We will describe our invention with reference to the accompanying
drawings
Figure 1 being a longitudinal section.
Figure 2 a transverse section (on the line 1, 2 Figure 1) and
Figure 3 an end view of an arrangement of apparatus according to our invention.
According to this invention we mount on brickwork or other suitable support A

page_text: a long cylinder B which may be constructed of boiler plate or other suitable material.
Lengthwise through it passes a shaft C provided with means for imparting rotary
motion thereto (illustrated by the wheel o) to which motion from any convenient
driver is transmitted. Upon this shaft inside the cylinder are mounted blades D
forming the segments of a helix or screw blade with spaces between the segments.
Theyare attached to the shaft byarms & so as to leave a space alsobetweenthe segments
and the shaft. These arms and segments are of such shape that as they revolve they
pass forward the material towards the outlet and at the same time lift and turn the
material. The material is introduced by the hopper E and is delivered in a dried
condition by the outlet F. The spaces between the segments allow the material to
remain a proper time in the cylinder for efficient drying. The heat which is applied
to the cylinder for drying may be either applied interually or externally, or both, for
instance, we may use an ordinary fire underneath the cylinder as at G with a flue
extending throughout any portion of its length or circumference, or we may use a
jacket or jackets as at H in Figure 4 for steam or hot water. In cases where we
introduce hot air into the cylinder we may effect the heating of the air prior to its
admission by causing it to pass through a supplemental casing surrounding or partly
surrounding the cylinder as at I Figure 4 and preferably arranged so that the inlet i
from this air casing to the cylinder is at the discharge end of the said cylinder., The
shaft C may be made hollow so as to admit of water being admitted thereto to prevent
it from getting too hot and damaging the bearings. The arms or segments or both,
may also be made hollow for the water to circulate through them also.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same_is_ to be performed we declare that what we
claim is.
1st. In an apparatusfordrying mineralsbrewers grains or other materials a cylinder
providedwith a shaft carrying segments D shaped and mounted as, and for the purpose,
herein before described.
2nd. The arrangement and combination of parts constituting a drying apparatus as
herein before described and illustrated in Figures 1, 2 and 3 of the accompanying
drawings also the modification thereof shewn in Figure 4. whether either the jacket H
or the air heating casing I be used, or both be used.
