CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF FURNACE DOORS FOR PUDDLING FURNACES
Year: 1869

page_text: LETTERS PATENT to William Goodreds, of Tipton, in the County of
Stafford, Ironfounder, for the Invention of "CERTAIN IMPROVEMENTS
IN THE CONSTRUCTION OF FURNACE DOORS FOR PUDDLING FURNACES."
Sealed the 2nd October 1869, and dated the 7th April 1869.
PROVISIONAL SPECIFICATION left by the said William Goodreds at
the Office of the Commissioners of Patents, with his Petition, on
the 7th April 1869.
I, WILLIAM GOODREDS, of Tipton, in the County of Stafford, Iron-
founder, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN THE CONSTRUCTION OF FURNACE DOORS FOR PUDDLING FURNACES.'
"
The object of this Invention is, by the means herein-after explained,
to preserve the furnace doors of puddling furnaces from burning, and
my Invention is also designed to protect puddlers working the furnace
from the excessive heat they now have to suffer.
My Invention consists substantially in introducing and preserving a
current of water through the furnace door. The inlet of the water is

page_text: at the top of the door, from whence it is carried round the stopper hole
of the door to the outlet which is at the bottom of the door. The
water may be carried by any convenient means, but by preference gas
tubing of a suitable size and kind is employed. The water is caused
to circulate continually through the pipe provided by any of the well-
known means usually employed for the forced circulation of water.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Goodreds in the Great Seal Patent Office
on the 7th October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GOODREDS, of Tipton, in the County of Stafford, Ironfounder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year
of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Goodreds, Her
special licence that I, the said William Goodreds, my executors, adminis-
trators, and assigns, or such others as I, the said William Goodreds, 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 Invention for "CERTAIN IM-
PROVEMENTS IN THE CONSTRUCTION OF FURNACE DOORS FOR PUDDLING FURNACES,'
upon the condition (amongst others) that I, the said William Goodreds,
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 William Goodreds, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
The object of this Invention is, by the means herein-after explained,
to preserve the furnace doors of puddling furnaces from burning, and my
Invention is also designed to protect puddlers working the furnace from
the excessive heat they now have to suffer.
My Invention consists substantially in introducing and preserving a
current of water through the furnace door. The inlet of the water is
at the top of the door, from whence it is carried round the stopper
hole to the outlet, as herein-after explained in the Drawings hereunto
annexed. The water may be carried by any convenient means, but by
preference gas tubing of a suitable size and kind is employed. The
water is caused to circulate continually through the pipes provided
by any of the well-known means usually employed for the forced
circulation of water. For the purpose of effectually cooling the front
of the door there may, if needed, be also provided a vessel in front of
the door, as shown in the Drawing herein-after described, and through
which vessel there is also caused to circulate a current of water. The
stopper hole in the furnace door may be constructed either with or
without loose pieces, but I find it an advantage to use loose pieces in its
construction, because of the ease with which they can be renewed from
time to time as necessary.
I now proceed to describe the Drawings hereunto annexed, which
will fully explain the details of my Invention.
Fig. I. is a front elevation, Fig. II. is an end elevation, and Fig. III.
is a horizontal section at the line A, B.
a is the door of the puddling furnace; b is the sill or fore plate of
the doorway; c is the inlet pipe conveying the water to the curved
pipe d, which is contained within the door a and passes over and near
to the stopper hole e. The water is discharged from the pipe f, which
is a continuation of the pipe d, into a slide box g. In order to allow
the door a to be opened and closed while the slide box remains stationary
the slide box g has a vertical slot or opening h, through which the
end of the pipe d enters and travels upwards or downwards as the
case may be. From the bottom of the slide box g the water passes
along the pipe i, which is contained within the door sill b; the door sill
is thus cooled. The water may be then used for any other purpose,
or may be allowed to run to waste. The strong dotted lines k represent

page_text: a box or vessel attached to the front of the door a in order to intercept
the heat therefrom. The vessel k may be supplied with water from
the inlet pipe c, a portion of the pipe c being removed from within
the box or vessel k, so that the box or vessel k forms a part of the
system of pipes through which the water passes on its way to the
outlet l.
Having now described the nature of my said Invention and the
manner in which the same is or may be performed, I desire it to be
understood that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is, the improvements in
the construction of doors for puddling furnaces, as herein-before described
and illustrated in the Drawings hereunto annexed, and which consist
substantially in introducing and preserving currents of water in, through,
or round the furnace door, as herein-before explained, and by means of
which puddlers working the furnace are protected from the excesive
heat they now have to suffer, and the furnace doors are preserved
from burning.
In witness whereof, I, the said William Goodreds, have hereunto
set my hand and seal, this Fifth day of October, 1869.
WILLIAM GOODREDS. (L.B.)
