Year: 1869

page_text: LETTERS PATENT to Julian Bernard, of Salisbury Street, Strand, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
SMELTING, AND IN FURNACES, MACHINERY, AND APPARATUS CONNECTED THERE-
WITH."
Sealed the 11th January 1870, and dated the 15th July 1869.
PROVISIONAL SPECIFICATION left by the said Julian Bernard at the
Office of the Commissioners of Patents, with his Petition, on the
15th July 1869.
I, JULIAN BERNARD, of Salisbury Street, Strand, in the County of
Middlesex, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN SMELTING, AND IN FURNACES, MACHINERY, AND APPARATUS CON-
NECTED THEREWITH," to be as follows:-
My improvements relate, firstly, to an improved mode of obtaining
a draught, which I effect by encasing a series of minute jets of water
alone or combined with gas or atmosphere in a shaft or cylinder, which
by preference I prefer to be vertical and suitably connected to or

page_text: forming part of a flue through which the draught is to be effected,
such jet or jets being forced into the flue under a considerable
pressure.
Secondly. To an improved furnace, the improvements consisting in
making or forming the lower bottom part of the furnace so as to be
independent or separate from the top or upper part, by which means
the lower portion can be readily removed, replaced, repaired, or taken
away without the necessity of disturbing the other portions; this I effect
by suspending or supporting the upper part or parts in any convenient
manner while the bottom or lower portion may be placed on a carriage
or slide for the greater facility of removal. The upper part of the furnace
may also be constructed so as to leave an air space between its inner
and outer portions through which air may be forced; this is effected
by means of a series of concentric rings or passages through which
the air is forced so as to take up the greatest amount of heat in its
passage.
This Invention relates, lastly, to an improved mode of feeding or
charging furnaces with fuel and with the material to be smelted by
mechanical or self-acting means, which I effect by placing the material
to be introduced into the furnace in a suitable receptacle, forming
part of a travelling or moveable carriage or platform, the whole so
formed, combined, and arranged that it can be readily introduced into
the furnace at the proper place and time, suitable movements and
arrangements being made for opening the furnace, moving the carriage
in and out, and actuating its different parts by cams and levers or
other suitable mechanism, so as to cause the materials to be deposited
or discharged at the proper time and in the exact position desired.
SPECIFICATION in pursuance of the conditions. of the Letters Patent,
filed by the said Julian Bernard in the Great Seal Patent Office on
the 15th January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JULIAN
BERNARD, of Salisbury Street, Strand, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of July, in the year of our

page_text: Lord One thousand eight hundred and sixty-nine, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Julian Bernard, Her special license that
I, the said Julian Bernard, my executors, administrators, and assigns,
or such others as I, the said Julian Bernard, my executors, adminis-
trators, or 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 SMELTING,
AND IN FURNACES, MACHINERY, AND APPARATUS CONNECTED THEREWITH," upon the
condition (amongst others) that I, the said Julian Bernard, my executors
or administrators, by an instrument in writing under my hand and
seal, 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 Julian Bernard, 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
following statement, reference being had to the accompanying Drawings
and to the letters and figures marked thereon, that is to say :-
My said Invention relates to an improved mode of feeding or charging
furnaces with fuel and with the material to be smelted by placing
the material to be introduced into the furnace in a suitable receptacle
forming part of a travelling or moveable carriage or platform, the whole
so formed, combined, and arranged that it can be readily introduced
into the furnace at the proper place and time, suitable movements and
arrangements being made for opening the furnace, moving the carriage
in and out, and actuating its different parts by cams and levers or other
suitable mechanism, so to cause the materials to be deposited or dis-
charged at the proper time and in the exact position desired.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the annexed Sheet of Drawings,
the same letters of reference indicating corresponding parts in all the
Figures.

page_text: Figure 1 of my Drawings is a plan, Figure 2 a side elevation, and
Figure 3 a part or detail of a machine which I employ for feeding or
charging furnaces more particularly employed for lead smelting.
The machine consists of a framing or carriage with wheels, which is
placed upon rails; its principal part consists of a sliding plate A capable
of being moved backwards and forwards by means of rack and pinion
B and C, motion being given to these parts by turning the wheels D.
The circular ring E, Figure 3, is placed upon the frame and occupies
the position shewn in the side elevation and dotted lines in the plan.
When a furnace is fed or charged by means of this machine the
materials to be inserted and smelted are placed in the receiver E in
such a position as it is considered most advisable they should be disposed
of in the furnace and in relation to the fuel, which in some cases is
inserted simultaneously with the material to be operated upon. The
machine is then moved by the attendant upon the rails F, F, until the
receiver occupies a central position in the furnace, by which time the
machine occupies the position on the rails which is represented, it being
ready for discharging its contents in the furnace; this is effected by the
attendant turning the wheel in such a direction as will withdraw the
plate or slide A, said plate being secured to the rack as shewn. As this
plate is withdrawn the material placed in the receiver falls in succession
through the different sections or divisions of the framing into the
furnace, and as may be desired as the plate is withdrawn; this ope-
ration performed the attendant withdraws the machine by releasing
the catch G by moving the carriage backwards upon the rails. By this
arrangement the material can be distributed in the furnace in any
desired position, and the fuel and material to be smelted distributed
and disposed in relation to each other with great nicety, and which
insures a more successful result in the operation of smelting. Furnaces
fitted with this arrangement have moveable sliding doors of sufficient
width to admit of such feeding apparatus.
Having now described and particularly ascertained the nature of my
Baid Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the peculiar
construction and arrangement of machinery or apparatus for feeding

page_text: or charging furnaces with fuel and with the material to be smelted or
operated upon, as herein-before described.
In witness whereof, I, the said Julian Bernard, have to this my
Specification set my hand and seal, the Fourteenth day of
January One thousand eight hundred and seventy.
