IMPROVEMENTS IN SINGE PLATES
Year: 1860

page_text: LETTERS PATENT to Joseph Pickles Jennings and Frederic Sarley Stott,
both of Bradford, in the County of York, Engineers and Ironfounders,
for the Invention of "IMPROVEMENTS IN SINGE PLATES."
PROVISIONAL SPECIFICATION left by the said Joseph Pickles Jennings
and Frederic Sarley Stott at the Office of the Commissioners of Patents,
with their Petition, on the 23rd March 1860.
We, JOSEPH PICKLES JENNINGS and FREDERIC SARLEY STOTT, both of
Bradford, in the County of York, Engineers and Ironfounders, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SINGE PLATES,"
to be as follows:-
The improvements consist in introducing a wrought iron, steel, or other
malleable framework or skeleton into the cast-iron singe plate, by which
means the singe plate is strengthened, and prevented from cracking by the
heat to which it is subjected, as it does generally, without the wrought iron,
steel, or other malleable frame. This wrought iron, steel, or other malleable
frame or skeleton being constructed of length bars connected by cross bars,
and lugs is placed into the mould previous to casting the singe plate, and is so
after the liquid iron has been poured over it, closely connected or incorporated
with the body of the cast iron to the above-mentioned effect.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Pickles Jennings and Frederic Sarley Stott in the
Great Seal Patent Office on the 22nd September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
PICKLES JENNINGS and FREDERIC SARLEY STOTT, both of Bradford, in the
County of York, Engineers and Ironfounders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of March, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Joseph Pickles Jennings, and Frederic Sarley Stott, Her special licence that
we, the said Joseph Pickles Jennings and Frederic Sarley Stott, our executors,
administrators, and assigns, or such others as we, the said Joseph Pickles
Jennings and Frederic Sarley Stott, our 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 SINGE PLATES," upon the condition (amongst others)
that we, the said Joseph Pickles Jennings and Frederic Sarley Stott, our
executors or administrators, by an instrument in writing under our, 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.
NOW KNOW YE, that we, the said Joseph Pickles Jennings and Frederic
Sarley Stott, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The improvements consist in introducing a wrought iron, steel, or other
malleable framework or skeleton into the body of the cast iron singe plate, by
which means the singe plate is strengthened, and effectually prevented from
cracking or breaking by the heat to which it is subjected when used, as it does
generally without the malleable framework or skeleton. This wrought iron,
steel, or other malleable frame or skeleton being constructed of length bars,
pierced with holes, connected by cross bars and lugs, is placed into the mould
previous to casting the singe plate, and so fixed therein, that after the liquid

page_text: iron has been poured over and allowed to fill the mould, it surrounds the
malleable frame or skeleton on all sides, so that the said malleable frame or
skeleton is closely connected or incorporated with the body of the cast-iron
singe plate, to the above-mentioned effect.
The length bars which form part of the frame we prefer making of flat iron,
steel, or other malleable substance, of dimensions varying with the size and the
strength of the singe plate, for which they are to be used, which flat bars are
pierced with holes, so that when the liquid iron is poured into the mould it
may fill each one of these holes, which will have the effect of uniting more
closely the cast-iron body of the singe plate and the malleable frame. These
length bars are connected or firmly fixed at each end by a cross bar, which we
also prefer of flat iron, steel, or other malleable substance, and between these
two end bars sometimes by other cross bars, which we then prefer either of
round or square iron, steel, or other malleable substance.
But that the nature of our said Invention, and in what manner we carry
the same into effect, may be fully understood, we will now proceed to describe
the Drawings annexed.
DESCRIPTION OF DRAWINGS.
In the annexed Sheet of Drawings Figure 1 is a front elevation, and
Figure 2a longitudinal section, through A, B, of a singe plate with our
improvements applied; Figure 3 shows a ground plan, and Figure 4 a
transversal section through C, D, of the malleable framework, in the applica-
tion of which our improvements consist. a, a, is the cast-iron body of the
singe plate; b, b, are the two end cross bars of the malleable frame; and
b, b, b, the length bars of the same, 6 and b, being firmly riveted into each
other, and 6 being perforated at certain distances with holes c, for the purpose
of uniting the malleable framework more closely to the cast-iron body of the
singe plate, by the liquid iron filling the holes c, c. Sometimes we prefer to
apply cross bars, as shown in d, d, but this is left to the option of the workman
wether and how many he thinks necessary. We also prefer making the
bars 6 and b₁, of flat iron, but square or round iron might be used for the same
purpose.
Having thus described the nature of our said Invention and in what manner
we carry the same into effect, we would have it understood, that we do not
confine ourselves to the precise details for fixing and constructing the wrought-
iron, steel, or other malleable framework or skeleton, as shown and described,
as these may be varied without departing from the peculiar character of our
improvements; but what we do claim is,-

page_text: Firstly, the system of introducing into the cast-iron body of singe plates a
malleable framework or skeleton, which has the effect of preventing the
breaking of them, substantially as described.
And, secondly, the combining and arranging of the said malleable frame, as
set forth in our Specification, or any mere mechanical alteration thereof.
In witness whereof, we, the said Joseph Pickles Jennings and Frederic
Sarley Stott, have hereunto set our hands and seals, this Twentieth
day of September, in the year of our Lord One thousand eight hundred
and sixty.
Witness,
ADOPH PFEILSCHMIDT.
