page_text: HIGGIN'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HIGGIN, of the City of Norwich, Shawl Manufacturer, send greeting.
WHEREAS His present Majesty King George the Fourth, by His Letters
Patent, under the Great Seal of Great Britain, bearing date at Westminster,
the Eighteenth day of August now last past, did give and grant unto me, the
said Robert Higgin, His especial licence, full power, sole privilege and
authority, that I, the said Robert Higgin, my executors, administrators, and
assigns, and such others as I, the said Robert Higgin, 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 of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick upon Tweed, my Invention of "A
NEW OR IMPROVED METHOD OF CONSUMING OR DESTROYING SMOKE;" in which
said Letters Patent there is contained a proviso obliging me, the said Robert
Higgin, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, and to cause the same to be inrolled in His
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said recited Letters Patent, as in and by
the said recited Letters Patent, reference being thereunto had, will more fully
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Higgin, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described and
ascertained as follows, that is to say:―

page_text: My Invention consists in having an extra or upper furnace placed in any
convenient and proper situation in the flue through or up which smoke passes
or ascends from the ordinary furnaces of breweries, distilleries, steam engines,
or any other concern or establishment where furnaces are used, and such
extra or upper furnace must be placed in such a position and at such part of
the flue as circumstances will render best adapted to give effect to the object
hereafter stated, and which any competent workman employed upon the
occasion will easily determine, and it must be so exactly fitted to the flue as
to prevent the escape or passage of any smoke from the ordinary furnace
without passing through such extra or upper furnace. Care must also be
taken to let the extra or upper furnace be sufficiently supplied with atmo-
spheric air in addition to what is common to the ordinary furnace, for without
such additional supply of atmospheric air the fire in the extra or upper furnace
will be in danger of being extinguished. The extra or upper furnace may be
supplied with cinders, coke, charcoal, or any other fuel which will not emit
smoke in its consumption, for the use of any fuel which does emit smoke in its
consumption would to a certain extent deminish the object of my Invention.
Previously to the kindling or lighting the fire in the ordinary furnace, the fire
should be kindled. or lighted in the extra or upper furnace and continued
burning till after the fire is extinguished in the ordinary or lower futziace, and
the smoke from the ordinary or lower furuace having no means of passing or
escaping except through the fire in the extra or upper furnace, it is thereby
consumed or destroyed.
In witness whereof, I, the said Robert Higgin, have hereunto set my
hand and seal, the Thirteenth day of February, in the year of our
Low One thousand simht bundund and
AND BE IT REMEMBERED, that on the same Thirteenth day of February,
in the year above mentioned, the aforesaid Robert Higgin came before
our Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all an everything therein contained, in form above written.
And also the Specification aforesaid was stamped according to the tenor of
the Statute in that case made and provided.
