Year: 1864

page_text: LETTERS PATENT to Morgan Morgans, of Brendon Hills, in the County
of Somerset, Engineer, for the Invention of "IMPROVEMENTS IN BLAST
FURNACES.":
Sealed the 8th November 1864, and dated the 10th May 1864.
PROVISIONAL SPECIFICATION. left by the said. Morgan Morgans at the
Office of the Commissioners of Patents, with his Petition, on the
10th May 1864 ? [......
I, MORGAN MORGANS, of Brendon Hills, in the County of Somerset,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN BLAST FURNACES," to be as follows:-
My Invention consists in constructing blast furnaces with a central core, by
preference conical, and extending upwards to any desired height in the
furnace. I insert tuyeres pointing inwards to the furnace in the core when
made hollow, and am thus enabled to introduce, when required, a blast through
the core in addition to the ordinary blast. In some cases the whole blast
may be driven through the central core. Or the core may be made solid, and
then the blast may be introduced in the ordinary manner.

TO ALL TO WHOM THESE PRESENTS, SHALL COME, I, MORGAN
MORGANS, of Brendon Hills, in the County of Somerset, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of May, in the year of our Lord One
thousand eight bundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the

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
BLAST FURNACES," upon the condition (amongst others) that I, the sail Morgan
Morgans, 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:
NOW KNOW YE, that I, the said Morgan Morgans, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol
lowing statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
My Invention consists in constructing blast furnaces with a central core,
by preference conical, and extending upwards to any desired height in the.
furnace. I insert tuyeres pointing inwards to the furnace in the core when
made hollow, and am thus enabled to introduce, when required, a blast through.
the core in addition to the ordinary blast. In some cases the whole blast;
may be driven through the central core. Or the core may be made solid; and
then the blast may be introduced in the ordinary manner.
Figure 1 of the accompanying Drawings is a vertical section, and Figure 2
is a plan on the line A, B, of Figure 1 of one of my blast furnaces; C is a

page_text: central core extending to the top of the furnace; D is a chamber inside the
core which may be entered at the bottom under the furnace, while the waste
gases may be carried off from the upper part.
The blue lines a, a, represent the centre lines of blast or tuyere irons,
through which blast may be forced from the inside of the central core, and
the lines b, b, represent the centre lines of tuyere irons for the blast from the
outside of the furnace; c, c, are tapping holes; Figure 3 is a vertical section,
and Figure 4 a plan on the line A, B, of Figure 3 of another of my furnaces;
C is the central core; D is the chamber which is entered at the sides; and
the annular hearth is shewn divided in two places, but the hearth may be
made to pass under the entrance arches as shewn in dotted lines in the plan;
a, a, and b, b, represent respectively the centre lines of internal and external
tuyere irons; c, c, are tapping holes; Figure 5 is a vertical section, and
Figure 6 a plan on the line A, B, of Figure 5, of another of my furnaces.
Here the chamber inside the core is dispensed with, as also the blast from
the interior; b, b, represent the centre lines of tuyere irons for the blast from
the outside; c, c, are tapping holes. The core C may be either hollow or
solid. Figures 7 and 8 are respectively vertical section and plan of a blast
furnace. The dotted lines shew the manner in which an ordinary blast
furnace as already constructed may be converted into one according to my
Invention, the central core C may be either hollow or solid; and the walls
between the core C, and the outer dotted lines d, d, must be removed; b, b,
represent the centre lines of the tuyere irons for the blast from the outside;
c, c, are tapping holes.
:
And having now. described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, constructing
blast furnaces with a central core substantially in manner herein-before
described and represented in the accompanying Drawings.
In witness whereof, I, the said Morgan Morgans, have hereunto set'
my hand and seal, this Ninth day of November, One thousand eight
hundred and sixty-four.
MORGAN MORGANS. (L.S.)
