Year: 1807

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BRADLY, of Maid Lane, Southwark, in the County of Surry, Ironfounder, do
send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Thirteenth day of July, in the
forty-seventh year of His reign, did give and grant unto me, the said James
Bradly, my executors, administrators, and assigns, His special licence, full
power, sole privilege and authority, that I, the said James Bradly, my exe-
cutors, administrators, and assigns, during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my new invented "IRON
BAB TO BE USED IN FIRE PLACES FOR BOILERS, FURNACES, HOTHOUSES, AND ANY
OTHER FIRE PLACE WHERE BARS ARE USED;" in which Letters Patent there
is contained a proviso obliging me, the said James Bradly, under my hand
and seal, to cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in His
Majesty's High Court of Chancery within one calendar month next and
immediately after the date of the said recited Letters Patent, as in
and by the same (relation being thereunto had) may more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
James Bradly, do hereby declare that my said Invention is described as follows,
that is to say-
My said Invention of a new kind of iron bar to be used in fire places for
boilers, furnaces, hothouses, or any other fire place where iron bars are used
consists in making the same hollow instead of solid, and in leaving them open
from one end to the other, so that air may pass through them, and this I
perform by casting them in the way that hollow things are usually cast, and
of any required shape or form, but the form which I prefer, and the
dimensions in general use for large fire places, are described in the margin
hereof. Care should be taken in placing these bars in the fire place so that the
air may have freo entrance and exit at both ends, by which means they will be
kept cooler than solid bars, and will not be subject to be burnt and wasted
like them from violent heat; but in case these bars should be placed by
accident or the carelessness or designs of the workmen so that their ends might
become closed with morter or other substance, I make them with a hole or
holes on each side and at opposite ends or at the lower edge of each bar, so
that the air may be freely admitted into them through these openings. The
advantage of making furnace bars hollow, so that the air may have a free passage
through them, is considerable, for, independent of their being capable by this
means of enduring a greater degree of heat than solid ones without injury,
they will last longer, will in a great degree prevent the coals from burning
to clinkers, and may be afforded for the same and perhaps less cost in the
Fig. 1, longitudinal view of a bar 24 inches long. a, a hole in one side
about ono inch diameter. A similar hole is made on the other side at the
opposite end.

In witness whereof, I have hereunto set my hand and seal, this Thirteenth
day of August, in the year of our Lord One thousand eight hundred
and seven.
