A NEW OR IMPROVED SELF-ACTING APPARATUS FOR DIS- TRIBUTING THE FEEDING MATERIALS IN HIGH FURNACES
Year: 1865

page_text: LETTERS PATENT to Alexander Prince, of the Office for Patents, No. 4,
Trafalgar Square, Charing Cross, in the County of Middlesex, for the
Invention of "A NEW OR IMPROVED SELF-ACTING APPARATUS FOR DIS-
TRIBUTING THE FEEDING MATERIALS IN HIGH FURNACES."-A communication
from abroad by Emile Langen, residing at Froisdorf, in the Kingdom of
Prussia.
Sealed the 22nd December 1865, and dated the 29th June 1865.
PROVISIONAL SPECIFICATION left by the said Alexander Prince at the
Office of the Commissioners of Patents, with his Petition, on the 29th
June 1865.
I, ALEXANDER PRINCE, of the Office for Patents, No. 4, Trafalgar Square,
Charing Cross, in the County of Middlesex, do hereby declare the nature of
the said Invention for "A NEW OR IMPROVED SELF-ACTING APPARATUS FOR DIS-
TRIBUTING THE FEEDING MATERIALS IN HIGH FURNACES," a communication to me
from abroad by Emile Langen, resident at Froisdorf, in the Kingdom of
Prussia, to be as follows:-
This Invention relates to a new or improved apparatus for distributing the
feeding materials, such as ores, limestone, flux, and charcoal, in high furnaces,
and consists in the combination of a hood or dome and a feeding or pouring-
in cone, having a series of boxes or guides on its surfaces, in which a corres-
ponding series of shovels are set and guided, being provided with friction
breaks, the guides serving to direct the course or action of the feeding shovels.

page_text: These distributing shovels extend beyond the edge of the cone towards its
apex, and their upper surfaces cause the coarser pieces to be thrown into the
middle of the fusing room, while the rubbish is left between the different
distributing shovels. The broader the shovels are made, and the further they
are extended into the furnace, the more the coarse pieces are conducted into
the middle of the furnace, and the smaller the shovels are, and the less they
are extended the more the materials are heaped against the wall of the
furnace. The cross sections of the distributing shovels may be Ṭ shaped, or
convex, or concave on the upper side, or they may have sloping surfaces from
the middle, or be of any desired form to suit the work required.
The apparatus is not only adaptable to the mouths of furnaces shut by a
cover, but to open mouths; it may be combined with the pouring-in cone,
but of course the apparatus is not applicable to furnaces when hand shovels
are used for feeding.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Prince in the Great Seal Patent Office on the
29th December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
PRINCE, of the Office for Patents, No. 4, Trafalgar Square, Charing Cross, in
the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of June, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alexander Prince, Her special licence that I, the said Alexander Prince,
my executors, administrators, and assigns, or such others as I, the said
Alexander Prince, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "A NEW OR IMPROVED
SELF-ACTING APPARATUS FOR DISTRIBUTING THE FEEDING MATERIALS, IN HIGH
FURNACES," a communication to me from abroad by Emile Langen, resident at
Froisdorf, in the Kingdom of Prussia, upon the condition (amongst others) thät
I, the said Alexander Prince, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly

page_text: 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 Alexander Prince, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This Invention relates to a new or improved apparatus for distributing the
feeding materials, such as ores, limestone, flux, and charcoal in high furnaces,
and consists in the combination of a hood or dome and a feeding or pouring-in
cone, having a series of boxes or guides on its surfaces, in which a corres-
ponding series of shovels are set and guided, being provided with friction
breaks, the guides serving to direct the course or action of the feeding shovels,
These distributing shovels extend beyond the edge of the cone towards its'
apex, and their upper surfaces cause the coarser pieces to be thrown into the
middle of the fusing room, while the rubbish is left between the different
distributing shovels. The broader the shovels are made, and the further they
are extended into the furnace, the more the coarse pieces are conducted into
the middle of the furnace; and the smaller the shovels are, and the less they
are extended, the more the materials are heaped against the wall of the furnace.
The cross sections of the distributing shovels may be T shaped, or convex, or
concave on the upper side, or they may have sloping surfaces from the middle,
or be of any desired form to suit the work required.
The apparatus is not only adaptable to the mouths of furnaces shut by
a cover, but to open mouths; it may be combined with the pouring-in cone,
but of course the apparatus is not applicable to furnaces when hand shovels
are used for feeding.
Fig. 1 is a plan of the apparatus; Fig. 2 its cross section. The apparatus,
as mentioned, is combined with a hood or dome and a pouring-in cone; there
are a certain number of little boxes, as to be seen in the cross section x, y,
fastened at the cone a, a, Fig. 2, in regular distances from one another.
Each of these little chests serves for the directrix of a shovel i, which is to be
regarded as a lengthening piece of the cone (with suitable breaks) in the
direction of the sliding level. The upper side of these shovels i, i, i, i, which
are called "distributing shovels," causes the coarser pieces to be tumbled into
the middle of the fusing room, while the rubbish is let through between the
different distributing shovels.
I claim as the Invention to be secured by the herein in part recited Letters

page_text: Patent the new or improved self-acting apparatus for distributing the feeding
materials in bigh furnaces, substantially as herein specified and shewn by the
Drawings annexed.
In witness whereof, I, the said Alexander Prince, have hereunto set my
hand and seal, this Twenty-ninth day of December, in the year of 5
our Lord One thousand eight hundred and sixty-five.
ALEX. PRINCE. (L.S.)
