IMPROVEMENTS IN DRYING MALT AND GRAIN
Year: 1843

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
POOLE, of Mornington Place, Camberwell New Road, in the County of
Surrey, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fifth day of May, in the sixth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Alfred
Poole, Her especial licence, full power, sole privilege and authority, that I,
the said Alfred Poole, my exors, adiñors, and assigns, or such others as I, the
said Alfred Poole, my exors, adññiors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN DRYING MALT AND GRAIN;" in which said
Letters Patent is contained a proviso, that I, the said Alfred Poole, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I the said
Alfred Poole, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to cov
Figures 1 and 2 are the two. end views of the furnace and apparatus
arranged according to my improvements; Figure 3 is a longitudinal section of
the apparatus; Figures 4 and 5 are two transverse sections of the apparatus;
Figure 4 being taken through the line marked a, a, in Figure 3, and the
section, Figure 5, is taken through the line b, b, in Figure 3; and Figures 6,
7, and 8 show a longitudinal section, a transverse section, and also a view of
one of the ends of the revolving cylinder into which the malt or grain to be
dried is put, the two ends being similarly formed; and Figure 9 is the door to
close the chamber in which the cylinder revolves, so as to prevent the escape
of heat in that direction. In all these Figures the same letters are used to
indicate the same parts wherever they occur.
The revolving cylinder consists of a frame c, c, covered with woven wire, or
otherwise made so open, that whilst it will retain the malt or grain, the vapours
arising therefrom may pass freely out and away from the cylinder. The cylinder
has a sliding door d for the introduction of the malt or grain to be dried, and for
discharging the same when dried; 9, 9, are inclined arms, which deflect off the
malt or grain, and change the positions of the same as carried round with the
cylinder. Rotatory motion is communicated to the cylinder c by means of the
crank handle j, affixed on the axis k, on which is affixed the fly-wheel / and the
pinion m. The pinion m takes into and drives the cog wheel n, affixed on the
axis e, which axis e turns in bearings at o, o, as is shown. p is a toothed rack,
which at one end has a collar 2, which embraces the hollow axis f, which is
capable of sliding on the axis e when it is desired to remove the cylinder from the
oven or chamber 1, 2, in order to discharge malt or grain from the cylinders c
into the truck or receiver s. The other end of the toothed rack p slides along
the frame or bar t, and motion is communicated to the toothed rack p (and
consequently to the cylinder c, so as to draw the cylinder c out of the oven r
into the position shewn by red lines in the longitudinal section, Figure 8,) by
means of the crank handle and pinion v, as will readily be understood on
examining the Drawings. u is a double cylindrical door, secured to the hollow

page_text: axis fat the right-hand end of the cylinder c, in order to prevent heat passing in
that direction from the oven r, such double cylindrical door nearly filling the
opening into the oven r, through which the cylinder centers and leaves the
oven . The oven within which the cylinder c works is heated externally by
a fire w, and the flues surround the larger portion of the oven so as to heat
the same, there being two chimneys x, x, having dampers, as shown, by which
the combustion of the fuel is regulated. At the upper part of the oven is also
applied a slide y, to regulate the passage of heat and vapour passing off in that
direction from the oven.
It is desirable here to remark that I am aware that malt and grain have
before been proposed to be dried by being placed in a revolving cylinder very
similar to that herein described, placed in a malt kiln or similar place where
the malt or grain under process would be liable to the direct action of the
heated air and products of combustion passing from the fuel by which such
kiln was heated. I would therefore call particular attention to the arrange-
ment herein described, where the oven or chamber in which the revolving
cylinder containing malt or grain works is so constructed that the malt or grain
under process of drying will not be subject to the direct action of heated air
and vapours from the fire, owing to the oven or chamber r being heated exter-
nally, and any heated air or vapours rising from the fire will not pass into the
oven, but be excluded therefrom; and it is the combining the use of a
revolving cylinder c within an oven or chamber externally heated which con-
stitutes the peculiar character of my Invention.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would wish it to be understood that I do not claim any of
the separate parts of the apparatus herein described, nor do I confine myself
to the precise details, so long as the peculiar character of the Invention be
retained.
And I would wish it to be understood that what I claim is, the combining a
rotatory cylinder or such like apparatus within an oven or chamber externally
heated, when for the purposes of drying malt or grain, as herein described.
In witness whereof, I, the said Alfred Poole, have hereunto set my hand
and seal, this Twenty-fifth day of November, in the year of our Lord
One thousand eight hundred and forty-three.

page_text: AND BE IT REMEMBERED, that on the Twenty-fifth day of November,
in the year of our Lord 1843, the aforesaid Alfred Poole came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification ȧfore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Enrolled the Twenty-fifth day of November, in the year of our Lord One
thousand eight hundred and forty-three.
