PROVISIONAL SPECIFICATION left by the said.Henry Mortlock
Omanney at the Office of the Commissioners of Patents, with
his Petition, on the 1st October 1852.
I, HENRY MORTLOCK OMMANNEY, of the City of Chester, Esquire,
do hereby declare the nature of the said Invention for "AN IMPROVED
FURNACE POR MELTING OF METALS IN CRUCIBLES." to be as follows, that is
to say:
My improved furnace for melting of metals: in crucibles consists in
arranging or building the furnace in compartments in such manner
as that the coke or other fuel is not brought into contact with the
crucibles. For this purpose I construct the furnace in, two or more
compartments, but I prefer three as the most convenient. If, three
compartments are used 'I call the centre compartment the crucible
chamber, into which I direct the flues from the other two, which may
be called the coke chambers, and which are best fed from above.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRY MORTLOCK OMMANNEY, of the City of Chester, Esquire, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October, in the
year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Henry Mortlock Ommanney, Her special
licence that I, the said Henry Mortlock Ommanuey, my executors,
administrators, and assigns, or such others, as I, the said Henry Mort-
lock Ommanney, 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 Inven-
tion for AN IMPROVED FURNACE FOR MELTING OF METALS IN CRUCIBLES,"
upon the condition (amongst others) that I, the said Henry Mortlock
Ommanney, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 I, the said Henry Mortlock Ommanney, do
hereby declare the nature of my 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 (that is to say):
My improved furnace for melting of metals in crucibles consists in
arranging or building the furnace in compartments in such manner as

page_text: that the coke is not brought into contact with the crucibles. For this
purpose I construct the furnace in two or more compartments, but I
prefer three or four as the most convenient. If three or four compart-
ments are used I call one of them the crucible chamber, into which I
direct the flues from the other two or three compartments, which may
be called the coke chambers, and which I have found advantageously
fed from above. I find
I find this arrangement of three or four chambers to
be the means of effecting a great saving of time, labor, and materials
over the furnaces for the purpose hitherto in use.
In witness whereof, I, the said Henry Mortlock Onimanney, have
hereunto set my hand and seal, this First day of April, in the
year of our Lord One thousand eight hundred and fifty-three.
H. M. OMMANNEY. (L.s.)
