Year: 1873

page_text: LETTERS PATENT to Edwin Clayton, of the Town and County of the
Town of Nottingham, Baker, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR FERMENTING DOUGH."
Sealed the 20th February 1874, and dated the 10th October 1873.
PROVISIONAL SPECIFICATION left by the said Edwin Clayton at the
Office of the Commissioners of Patents, with his Petition, on the
10th October 1873.
I, EDWIN CLAYTON, of the Town and County of the Town of Notting-
ham, Baker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR FERMENTING DOUGH," to be as follows:-
When the batch is made I place upon the upper surface of the batch
within the working trough the flame of a lamp, gas burner, or other
apparatus producing a flame, and on the under side of the trough lid I
attach a metal plate or shield in such position as to be immeadiately over

page_text: the flame to protect the lid from being burnt by it; and I perforate the
lid of the trough and plate and insert a tube therein to carry off any
objectionable matter that may arise, the effect of which is that the
fermenting properties of the batch is improved and purified.
the 25th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN
CLAYTON, of the Town and County of the Town of Nottingham, Baker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edwin Clayton, Her special licence
that I, the said Edwin Clayton, my executors, administrators, and
assigns, or such others as I, the said Edwin Clayton, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN FERMENTING
DOUGH," upon the condition (amongst others) that I, the said Edwin
Clayton, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
TAY ZNAM VE that T the said Edwin Clayton do hereby declare

page_text: performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawing
forming a part of this Specification:―
When the batch is made I place upon the upper surface of the batch
within the working trough the flame of a lamp, gas burner, or other
apparatus producing a flame, and on the under side of the trough lid I
attach a metal plate or shield in such position as to be immediately over
the flame to protect the lid from being burnt by it; and I perforate the
lid of the trough and plate and insert a tube therein to carry off any
objectionable matter that may arise; the effect of which is that the
fermenting properties of the batch is improved and purified.
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 are sectional views of a working trough; Figure 1
represents the lid of the trough closed; and Figure 2 shews the lid open.
In carrying out my Invention I proceed as follows :-When the batch
is made I place upon the upper surface of the batch within the working
trough A, or other vessel, a tray B of wood or other suitable material;
upon this tray I place a lamp, gas burner, or other apparatus producing
a flame C; in Figure 1 the flame is shown produced by a lamp, and in
Figure 2 by means of gas, which is conducted to a suitable burner or
burners by a flexible tube D communicating with an adjacent gas pipe E;
the tray is employed to lift the flame as the batch rises, and on the under
side of the trough lid I attach a metal plate or shield F in such position
as to be immediately over each flame to protect the lid from being
burnt; and I perforate the lid of the trough or other vessel and plate
and insert a tube F" therein to carry off any objectionable matter that
may arise.
In Figure 1 the batch is shown before it has risen; and Figure 2
shows the batch when it has risen.
By employing a flame within the working trough or other vessel, as
above described, the fermenting properties of the batch are improved
and purified, and the batch rises in considerably less time than by the
means heretofore employed.
Having now described the nature of the Invention, and the manner of
performing the same, I declare that I claim, the apparatus arranged and

page_text: employed as above described, and illustrated in the Drawing annexted,
for the purpose set forth.
In witness whereof, I, the said Edwin Clayton, have hereunto set
my hand and seal, this Twenty-fourth day of February, in the
year of our Lord One thousand eight hundred and seventy-four.
Witness,
H. W. GOUGH, C.E.,
Nottingham.
