IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRYING, CLEANING AND
DRESSING, WHEAT, BARLEY, OATS, MALT, RICE AND OTHER GRAIN AND ALSO
FOR DRYING AND TREATING OTHER MATTERS AND MATERIAL.
"
The said invention relates to drying, cleaning and dressing wheat, barley, oats,
rice, malt, damp grain, seeds and other agricultural products also in treating and
drying drysalteries and other matters and material preparatory to grinding or when
ground.
For this purpose I fit three frames at a suitable distance from each other and
stay the same with wrought iron bars or with wrought iron tubes which are secured
in position by nuts; the frames are made with inside curved tops and brackets on
which rest at each end of the apparatus circular steam chests; in the side plates
of these steam chests are secured the ends of long tubes which extend nearly the
length of the machine, the tubes are secured in the plates of the steam chests by
nuts inside and outside of the plates. On each side of the steam chests and on the
tops of the frames are fitted plummer blocks through which pass and work shafts
extending the length of the machine and on which are secured grooved pullies; the
shafts are actuated by pullies driven by belting; in the grooves of the pullies work
angular projecting rings which are cast on the top of broad rings; in the inside of
these broad rings are cast projecting angular brackets; to some of these brackets
are secured long flat stays extending the length of the machine, on the other

page_text: brackets are secured broad flat bars fixed at an angle for the purpose of lifting and
turning the grain, seeds or other material operated on and give a free action to the
current of heated air through the same; one, two or more of these flat bars is or
are fitted through the length with moveable angular castings which are secured on
a bar extending the length of the tubes or nearly so, the bar works in bearings
secured inside the broad ring, and, the bar is actuated by a small hand wheel to
allow of setting the movable castings to any desired angle to give more or less
speed to the delivery of the grain, seeds or other material operated on.
A steam pipe is fitted to the cover of the steam chest on the feeding side which
furnishes steam to the steam tubes of the apparatus and the cover is also fitted with
a hopper which is fitted in the centre of the steam chest cover, with a tubular
casting in which is fitted a worm which delivers through the open end of the
tubular casting the grain, seeds etc witbin the inside of circular revolving
casings which are secured to the rings having angular projecting circles and which
work in the grooves of the grooved pullies, the grooved pullies actuate the circular
casings which revolve round the fixed steam tubings and keep turning and agitating
the grain etc; whilst the broad long levers keep lifting and turning the same, the
worm is actuated by a small pulley which receives action from a belt working over
a pulley fitted on one of the shafts of the grooved pullies.
The steam chest of the other end is fitted with an upright chamber which is
connected with a fan which exhausts the heated air dirt or vapour from the
revolving circular casings as the operation of drying, cleaning and dressing proceeds
and in the bottom part of the machine and at the delivery end is made an opening
which discharges through a shoot the grain, seeds or other material that has or have
been operated on and which is or are kept moving forward by the moveable angular
guides and which falls or fall into suitable receivers; a chamber is also fitted in
front of the delivery side, which leads to an opening in the side of the fan, and
which exhausts through the fan and out of the delivery opening any light matter
or dust coming from the grain etc; a pipe is fitted to the delivery steam chest to
discharge the steam and condensed water, this pipe is connected to an equilibrium
valve and guards are fitted in the inside of the tubular castings and also on the
outside of the delivery side to prevent the escape of grain, seeds or other
material.
One of the tubular castings or each tubular casting can be removed and a wire
net fitted over the tubes and secured to the broad circular rings and a fire place,
and fire bars can be fitted under the apparatus on which a fire can be made and act
upon the grain, seeds, etc. instead of, or in combination with the steam, this latter
application is more specially intended to dry malt, oats and other grain which is
or are at present dried in kilns, producing a more even drying of each grain.

JAMES WALWORTH of Bradford in the county of York, Corn Mill Engineer
"IMPROVEMENTS IN MACHINERY
AND
OR APPARATUS FOR DRYING, CLEANING
DRESSING WHEAT, BARLEY, OATS, MALT, RICE AND OTHER GRAIN AND ALSO FOR
DRYING AND TREATING OTHER MATTERS AND MATERIAL.
"'
The said invention relates to drying, cleaning and dressing, wheat, barley, oats,
rice, malt, damp grain, seeds and other agricultural products, also to treating and
drying drysalteries and other inatters and material preparatory to grinding or
when ground.
In order to enable my invention to be better understood I will proceed to
describe the saine by reference to the accompanying drawing in which figure 1,
represents a sectional side elevation of my improved apparatus, figure 2, is a side
elevation, and figure 3 an end elevation of the same.
Figure 4, represents a section through the circular or tubular casing shewing the
steam pipes and lifting and turning and agitating gear. Similar letters of reference
are employed to represent similar parts.
For this purpose, I fit three frames A, at a suitable distance from each other and
stay the same with wrought iron bars or with wrought iron tubes B secured in
position by nuts C; the frames are made with inside curved tops and brackets on
which rest at each end of the apparatus circular steam chests D; in the side plates
of these steam chests are secured the ends of long tubes E which extend nearly
the length of the machine; the tubes are secured in the plates of the steam chests
by nuts F, inside and outside the plates.
On each side of the steam chests and on the tops of the frames are fitted plummer
blocks G through which pass and work shafts H, extending the length of the
machine and on which are secured grooved pullies I; the shafts H, are actuated by
pullies J, driven by belting; in the grooves of the pullies work angular projecting
rings K cast on the tops of broad rings L and in the inside of these broad rings are
cast projecting angular brackets M; to some of these brackets are secured long flat
stays N, extending the length of the machine and on some of the brackets are
secured broad flat bars O fixed at an angle for the purpose of lifting and turning
the grain, seeds or other material to be operated on and for giving a free action to
the current of heated air through the same; one, two, or more of these flat bars is
or are fitted throughout their length with movable angular castings P, secured on
a bar extending the length of the tubes or nearly so; the bar works in bearings
secured inside the broad ring and is actuated by a small hand wheel Q which allows
of setting the movable castings to any desired angle to give more or less speed to
the delivery of the grain, seeds or other material operated on. A steam pipe is
fitted to the cover of the steam chest on the feeding side which furnishes steam to
the steam tubes of the apparatus and the cover is also fitted with a hopper R fitted
in the centre of the steam chest cover with a tubular casting S in which is fitted a
worm T which delivers the grain, seeds, or the like through the open end U of
the tubular casting, into the inside of circular revolving casings V secured to the
rings L having angular projecting circles which work in the grooves W of the
grooved pullies I; the pullies I actuate the casings V which revolve round
the fixed steam tubes E and keep turning and agitating the grain or the like whilst
the long broad bars O keep lifting and turning the same. The worm T is actuated

page_text: by a small pulley X which receives action from a belt working over a pulley fitted
on one of the shafts of the grooved pullies I.
The steam chest at the other end of the apparatus is fitted with a vertical
chamber Y connected with a fan Z which exhausts the heated air, dirt or vapour
from the revolving circular casings V as the operation of drying, cleaning and
dressing proceeds; in the bottom part of the machine and at the delivery end an
opening A', is formed which discharges through a shoot B' the grain, seed or other
material which has been operated on and which is kept moving forward by the
movable angular guides and the discharged grain, seed or other material falls into
suitable receivers; a chamber is also made leading to the opening at the side
of the fan Z and which exhausts through the fan and out of the delivery opening
any light matter or dust coming from the grain or the like; a pipe is fitted to the
delivery steam chest to discharge the steam and condensed water and this pipe is
connected with an equilibrium valve; guards are fitted in the inside of the tubular
casings and on the outside of the delivery side so as to prevent the escape of grain,
seeds or other material.
One of the tubular casings or each tubular casing V can be removed and a wire
net or casing D' is fitted over the tubes E and secured to the broad circular
rings L; a fire place and fire bars can be fitted under the apparatus on which a
fire can be made to act upon the grain, seeds or the like instead of steam or in
combination with the steam and this latter application is more especially intended
for drying malt, oats and other grain (which is at present dried in kilns) by which
means I produce a more even drying of the grain.
Having thus described my improvements and the best means I am acquainted
with for carrying the same into effect I would have it understood that what I
claim is :-
Firstly. The combination of parts forming the improved machine or apparatus
for drying, cleaning, and dressing wheat, barley, oats, malt, rice and other grain
and for drying and treating other matters and material, substantially in the manner
and for the purposes hereinbefore described and illustrated in the accompanying
drawing or any mere modifications thereof.
or
Secondly. The construction and employment of the improved machine
apparatus for drying, cleaning and dressing, wheat, barley, oats, malt, rice and
other grain and for drying and treating other matters and material, substantially as
herein before described and represented in the accompanying drawing.
In Witness whereof I the said James Walworth have hereto set my hand
and seal this ninth day of September in the year of our Lord one
thousand eight hundred and eighty two.
