Year: 1820

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, late of Gospel Oak, in the Parish of Sedgley, but now of the Parish.
of Wednesbury, in the County of Stafford, Furnace Worker, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did,
by His Letters Patent under the Great Seal of that part of the United
Kingdom of Great Britain and Ireland called England, bearing date at
Westminster, the Twenty-third day of October, in the first year of His reign,
give and grant unto me, the said William Taylor, my exors, admiors, and
assigns, His especial licence, full power, sole privilege and authority, that
I, the said William Taylor, my exors, adññiors, and assigns, during the term of
years therein mentioned, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "AN IMPROVED FURNACE FOR THE SMELTING OF IRON AND OTHER.
ORES;" in which said Letters Patent there is contained a proviso that if I, the
said William Taylor, shall not particularly describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed,
by an instrument in writing under my hand and seal, and cause the same to
be inrolled in His Majesty's High Court of Chancery within six calendar
month next and immediately after the date of the said Letters Patent, that.
then the said Letters Patent, and all liberties and advantages whatsoever
thereby granted, shall utterly cease, determine, and become void, as in and by
the same, relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Taylor, do hereby declare that the nature of my said Invention, and

page_text: manner in which the same may be, performed, are particularly described and
ascertained in and by the Drawings hereunto, annexed, and the following
description thereof, that is, to say-
That my Invention doth consist in An Improved Furnace for the Smelting of
Iron and other Ores, the hearth of which is so constructed that the blast may
be conveyed into it through two or more holes or apertures made in one and
the same side or sides, or the front or the back of the hearth; either any or
all of the same one or more of such holes or apertures being opened or made
at a height or heights from the bottom of the hearth greater or less than the
other or others of them, by which means the blast is distributed equally through
the whole of the fire contained in the hearth.
DESCRIPTION OF THE DRAWING.
Fig. 1. The whole of that part of the furnace represented in the Drawing as
square, and contained within the framework x, x, x, x, x, x, I call the hearth.
A represents the back, and B the side of a hearth. c, c, c, c, c, are twyer holes
for the admission of the blast, which is conveyed into the hearth through blow
pipes, as at T, T, T, T. It will be seen that these twyer holes are at various
heights from the bottom of the hearth or internal floor H, H, Figure 2.
They may be at any convenient distance above one another, perpendicularly
or otherwise, but the height that I have found most useful is about fourteen
or fifteen inches. The lower twyer holes I prefer to be about twenty-four
inches from the bottom of the hearth or internal floor. "P, P, represent a part
of the cupola.
The different parts of the furnace are built of the ordinary materials, and
(with the exception of the twyer holes, as herein-before explained) of the
ordinary form.
Figure 2 is a section, from back to front, of what I call the hearth, of which
H, H, is the internal floor; T, T, T, T, the blow pipes; and c, c, c, twyer
holes; R is the tap hole.
Figure 3 is a section from side to side of the same.
Now a furnace having its hearth so furnished with twyer holes situated as
aforesaid being, to the best of my knowledge and belief, entirely new, and
never before used in these Kingdoms, I am desirous to maintain this my
exclusive right and priviledge to the same.
In witness whereof, I, the said William Taylor, have hereunto set my
hand and seal, this Twenty-first day of April, in the year of our
Lord One thousand eight hundred and twenty-one.
WILLIAM (L.S.) TAYLOR.
