We ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER, both of the Castle
Brewery St. George's Road, Southwark in the County of Surrey, Consulting Practical
Browers and Analatical Chemists, do hereby declare the nature of this invention to be
as follows:-
The invention has for its object a peculiar arrangement and combination of machinery
or apparatus for drying grain and is more particularly designed for the drying of
grain which has been soaked and steamed in order to prepare it for use in brewing,
distilling and vinegar making.
In carrying our invention into effect we employ a pair of inclined hollow cylinders
arranged one above the other and mainly enclosed within a close chamber heated by a
furnace contained within or underneath such chamber or exterior thereof.
The upper cylinder is inclined say from left to right and, the lower cylinder from
right to left so that the lower end of the upper cylinder and the upper end of the
lower cylinder are near each other.
The ends of these cylinders project a short distance through opposite walls of the
heating chamber where they are supported by wheels running in grooved rings fixed
around such cylinders. The upper end of the upper cylinder is fed continuously by a
worm or screw which delivers the grain into a hopper the lower tubular end of which
enters a short distance into said cylinder; the lower end of the upper cylinder delivers
the grain into the upper end of the lower cylinder by means of a hopper into which
the end of the said cylinder enters a short distance and the lower end of which hopper
enters a short distance into the lower cylinder through an axial opening in the end
thereof.
The lower end of the lower cylinder just within the heating chamber is formed
with an opening or openings in the side thereof through which the dried grain is
delivered into a hopper or shoot which delivers the dried grain outside the said
heating chamber.
The upper end of the upper cylinder is continued beyond the feed apparatus and
is connected with the Aue

and we drive them by means of chains in the following manner; around one end of
each of the cylinders we fix toothed rings and intermediate of adjacent cylinders
we arrange guide chain wheels and we drive all the cylinders by an endless chain
wheel which passes partly around the toothed rings with which it is kept in contact
by the guide wheels, said chain also passes partly around a driving wheel and partly
around a straining wheel which is capable of movement in its bearings so as to apply
the requisite tension to the chain.
If desired instead of employing chain wheels and an endless chain for driving these
cylinders toothed or worm gear may be used in lieu thereof.
A supporting wheel is placed on each side of the lower part of each cylinder and

gradually advanced through the cylinders.
The heating chamber is provided with apertures through which air may be admitted
for the purpose of regulating or reducing the temperature within such heating chamber
and the furnace is provided with means whereby the products of combustion may be
diverted from the heating chamber and carried directly into the main flue.
The action of the apparatus is as follows:-
The grain gradually finds its way from the feeding end of the upper cylinder to the
delivery end of the lower cylinder where it is discharged into the delivery hopper or
shoot which delivers the grain to the exterior of the heating chamber; the products
of combustion from the furnace pass into the heating chamber and heat the cylinders,
as however there is no outlet from said chamber except through the cylinders the
products of combustion pass into the discharge apertures of the lower cylinder and
after travelling through both cylinders find their way into the flue.

page_text: Improvements in Machinery or Apparatus for Drying Grain.
We, ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery, St. Georges Road, Southwark in the County of Surrey, Consulting Practical
Brewers and Analytical Chemists, 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 invention has for its object a peculiar arrangement and combination of machinery
or apparatus for drying grain and is more particularly designed for the drying of
grain which has been soaked and steamed in order to prepare it for use in brewing,
distilling and vinegar making.
In carrying our invention into effect we employ a pair of inclined hollow cylinders
arranged one above the other and mainly enclosed within a close chamber heated by a
furnace contained within or underneath such chamber or exterior thereof.
The upper cylinder is inclined, say from left to right and the lower cylinder from
right to left so that the lower end of the upper cylinder and the upper end of the
lower cylinder are near each other.
The ends of these cylinders project a short distance through opposite walls of the
heating chamber where they are supported by wheels running in grooved rings fixed
around such cylinders. The upper end of the upper cylinder is fed continuously by
a worm or screw which delivers the grain into a hopper the lower tubular end of which
enters a short distance into said cylinder, the lower end of the upper cylinder delivers
the grain into the upper end of the lower cylinder by means of a hopper into which
the end of the said upper cylinder enters a short distance and the lower end of which
hopper enters a short distance into the lower cylinder through an axial opening in the
end thereof.
The lower end of the lower cylinder just within the heating chamber is formed
with an opening or openings in the side thereof through which the dried grain is
delivered into a hopper or shoot which delivers the dried grain outside the said heating
chamber. The upper end of the upper cylinder in continued beyond the feed apparatus
and is connected with the flue.
We preferably arrange several pairs of such cylinders in a single heating chamber
and we drive them by means of chains in the following manner; around one end of
each of the cylinders we fix toothed rings and intermediate of adjacent cylinders we
arrange guide chain wheels and we drive all the cylinders by an endless chain which
passes partly around the toothed rings with which it is kept in contact by the guide
wheels, said chain also passes partly around a driving wheel and partly around a
straining wheel which is capable of movement in its bearings so as to apply the requisite
tension to the chain. If desired instead of employing chain wheels and an endless
chain for driving these cylinders toothed or worm gear may be used in lieu thereof.
A supporting wheel is placed on each side of the lower part of each cylinder and

page_text: where more than one pair of cylinders is employed a single intermediate supporting
roller may be employed to partially support each cylinder.
The cylinders are fitted around the interior with a number of blades or lifters so that
in revolving the grain shall be lifted and then dropped whereby the grain is gradually
advanced through the cylinders.
The heating chamber is provided with apertures through which air may be admitted
for the purpose of regulating or reducing the temperature within such heating chamber
and the furnace may be provided with means whereby the products of combustion may
be diverted from the heating chamber and carried directly into the main fluo.
And in order that our said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section and Figure 2 is an end elevation of grain drying
machinery or apparatus constructed according to our invention. In both figures like
parts are marked with similar letters of reference.
In carrying our invention into effect we employ a pair of inclined hollow cylinders
A, A¹ arranged one above the other and mainly enclosed within a close chamber B
heated by a furnace C contained within such chamber B as represented in the drawings
or the furnace C may be either underneath or exterior of such chamber.
The upper cylinder A is inclined in one direction and the lower cylinder A¹ in the
contrary direction so that the lower end of the upper cylinder A and the upper end of
the lower cylinder A' are near each other.
The ends of these cylinders A, A¹, project a short distance through opposite walls D, D
of the heating chamber B where they are supported by wheels e. e. running in grooved
rings a. a. fixed around each end of such cylinders. The supporting wheels e. e. are
mounted in suitable bearings carried by guides E fixed at their ends in vertical
supports D¹, D¹.
The upper end of the upper cylinder A is fed continuously by a worm or screw f
which delivers the grain into a hopper g the lower tubular end g¹ of which enters a
short distance into said cylinder A; the worm or screw f is mounted in bearings h
at the ends of the cylinder h enclosing the same and said cylinder h is provided with
a hopper which is kept continually supplied with the grain to be dried. Motion is
given to the worm or screw by means of a bevelled pinion f¹ fixed on the axis thoroof
and driven by a bevelled pinion on the shaft or axis i which is driven by a strap or
band from an engine or otherwise as may be found convenient. Thus a single shaft
or axis i may be employed to drive a number of these worms or screws, as many
bevelled pinions i¹ being fixed thereon as there are worms or screws f to be driven.
The lower end of the upper cylinder A delivers the grain into the upper end of the
lower cylinder A¹ by means of a hopper j into which the end of the said upper cylinder A
enters a short distance and the lower cylindrical end j¹ of which hopper enters a
short distance into the lower cylinder A' through an axial opening in the end thereof.
The lower end of the lower cylinder A' just within the heating chamber B is formed
with openings a¹ in the side thereof through which the dried grain is delivered into a
hopper or shoot k which delivers the dried grain outside the said heating chamber B
where said grain may be conveyed to any desired point by means of a worm or screw
working within a trough P.
The upper end of the upper cylinder A communicates with the chimney by means
of the tubular end g¹ of the hopper 9 which tubular end g¹ in continued beyond the
feed apparatus and is connected with the flue.
The
We preferably arrange several pairs of such cylinders A A¹ in a single heating
chamber B in the drawings we have represented a combination of three pairs of such
cylinders and we drive them by means of chains m in the following manner.
rings a on one end of each of the cylinders A A' are provided with toothed rings a
and intermediate of adjacent cylinders we arrange guide chain wheels n and we drive
all the cylinders by an endless chain m which passes partly around the toothed rings a²

page_text: with which it is kept in contact by the guide wheels n, said chain m also passes partly
around guide wheels p. pl and partly around a straining wheel q, this latter is capable
of movement in its bearings by means of a screw q', acting upon the frame ², carrying
said bearings by which means the requisite tension may be applied to the chain. The
chain guide wheel pl acts also as the chain driving wheel, it is fixed on the shaft or
axis pon which is also fixed a bevelled wheel p³ which is driven by a bevelled
pinion p' on the shaft or axis p' and this latter is driven by a chain (not shown) passing
around the chain wheel p fixed thereon. Other suitable means may however be
employed to give motion to the wheel p¹. If desired instead of employing chain
wheels and an endless chain for driving these cylinders A. A¹ toothed or worm gear
may be used in lieu thereof.
A supporting wheel e is placed on each side of the lower part of each cylinder A A¹
in cases where only one pair of such cylinders is employed and such may also be the
case where several pairs of such cylinders are employed as shown by the full lines in
Figure 2 but if desired a single intermediate supporting roller e may be employed to
partially support each cylinder A, A', as shown by the dotted lines in Figure 2. The
cylinders A A¹ are fitted around the interior with a number of blades or lifters a³ so
that in the revolution of the said cylinders the grain shall be lifted and then dropped
whereby the grain is gradually advanced through the cylinders.
The heating chamber B is provided with apertures b. b. through which air may be
admitted for the purpose of regulating or reducing the temperature within such
heating chamber B suitable dampers or valves being employed in connection with such
apertures b. b. for the said purpose.
If desired the furnace instead of being enclosed within the chamber B may be
placed underneath or exterior of said chamber in which case it will be provided with
means whereby the products of combustion may when required be directed into and
diverted from the heating chamber B in which latter case they would be carried
directly into the main flue.
The action of the apparatus is as follows:-
The grain gradually finds its way from the feeding end of the upper cylinder A to
the lower end thereof thence through the hopper j into the upper end of the lower
cylinder A¹ and after traversing to the lower end of such cylinder it is. discharged
therefrom through the apertures a¹ into the delivery hopper or shoot k which delivers
the grain to the exterior of the heating chamber B, the products of combustion from
the furnace C pass into the heating chamber B and heat the cylinders A A¹ as however
there is no outlet from said chamber B except through the cylinders A A' the products
of combustion pass into the lower cylinder A' through the discharge apertures a¹ and
after travelling through both cylinders find their way into the flue.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
The peculiar combination and arrangement of machinery or apparatus for drying
grain substantially as herein shown and described.
