IMPROVEMENTS IN THE CONSTRUCTION AND HEATING OF PROVISIONAL SPECIFICATION
Year: 1881

page_text: LETTERS PATENT to Alfred Savill Tomkins, Frederic Michell Courage, and
Frank Arthur Cracknall, of 61, Mark Lane, London, Malt Factors, for an
Invention of " IMPROVEMENTS IN THE CONSTRUCTION AND HEATING OF
PROVISIONAL SPECIFICATION left by the said Alfred Savill Tomkins,
Frederic Michell Courage, and Frank Arthur Cracknall, at the Office of the
Commissioners of Patents on the 7th February 1881.

CONSTRUCTION AND HEATING OF KILNS FOR DRYING MALT, GRAIN, OR OTHER
MATERIALS."
the
Figures 1 & 2 in the Drawings annexed are plan views of the lower and the
upper parts of the kiln respectively; No. 3 is a sectional elevation; and No. 4
represents the hot plate, which is a case, into which the heat and fumes of the
furnace are discharged and carried off by one or more chimnies (four are shown in
the Drawing) placed at a distance from the furnace. Air is supplied to the kiln
by air ducts (which may pass near the chimnies) discharging under the ash pit, so
that the already partially heated air by the help of bafflers has to pass under and
over the hot plate before reaching the kilns, of which there may be several, one
above the other, two being shewn in the Drawing. A separate air-duct supplies
the furnace. The temperature is placed under complete control by dampers, being
adjusted to all the air and smoke or fume ducts. The advantages of this kiln are
that a furnace consuming its own smoke may be employed, and any kind of fuel
can be used; that the fumes from the furnace do not pass through the grain or
material being dried; that the under heat of the furnace and ash pit, as well as the
Great regularity
upper heat, are employed in raising the temperature of the kiln.
of temperature can be maintained, and malt and other grain can be cured highly
without imparting colour, and with great economy of fuel. Having now described

page_text: the nature of our said Invention, and in what manner the same is to be performed,
we declare that we do not confine ourselves to the precise details herein specefied,
as the same may be varied without departing from the nature of the said Invention,
but what we claim and wish to secure is the so forming, arranging, combining, and
constructing the said parts or apparatus constituting our Invention for improvements
in the construction and beating of kilns for drying malt, grain, or other materials,
substantially as set forth.
SPECIFICATION 'n pursuance of the conditions of the Letters Patent filed by
the said Alfred Savill Tomkins, Frederic Michell Courage, and Frank Arthur
Cracknall, in the Great Seal Patent Office on the 11th July 1881.

showing the heating apparatus; Figure 3 is a plan view of the upper part of the kiln
showing the kiln wire and smoke and air ducts; Figure 1 is a sectional elevation.

placed at a distance from the furnace. Air is supplied to the kiln by air-ducts,
which may pass near the chimnies, discharging under the ash-pit and hot-plate, so
that the already partially heated air has, by the help of bafflers, to pass under, over,
and through hot plates before reaching the kiln.. A separate air duct supplies the
furnace. The temperature is placed under complete control by dampers being'
adjusted to all the air and smoke or fume ducts.
The advantages of this kiln, are that a furnace consuming its own smoke may be
employed, and any kind of fuel can be used; that the fumes from the furnace do
not pass through the grain or material being dried; that the under heat of the
furnace and ash-pit as well as the upper heat is employed in raising the temperature
of the kiln. Great regularity of temperature can be maintained, and malt and
other grain can be cured highly without imparting colour. There is also a great
saving of fuel:
Having now described the nature of our said Invention and in what manner the
same is to be performed, we declare that we do not confine ourselves to the precise
details herein specified, as the same may be varied without departing from the
nature of the said Invention, but what we claim and wish to secure is the so
forming, arranging, combining, and constructing the said parts or apparatus

page_text: constituting our said Invention for improvements in the construction and heating
of kilns for drying malt, grain, or other materials, substantially as set forth.
In witness whereof, we, the said Alfred Savill Tomkins, Frederic Michell
Courage, and Frank Arthur Cracknall, have hereunto set our hands and
seals, this Eleventh day of July, in the year of our Lord One thousand
eight hundred and eighty one.
