page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
CROSS, of Quaker's Brook within Hoghton, in the County County of Lancaster,
Tanner, and THOMAS SOUTHWORTH, of Hoghton aforesaid, Cotton Manufac-
turer, send greeting.
WHEREAS His present Majesty King George the Third, by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Thirty-first day of December now last past, hath given and granted unto
us, the said Robert Cross and Thomas Southworth, our executors, administra-
tors, and assigns, special licence, full power, sole privilege and authority, to
make, use, exercise, and vend within that part of the United Kingdom of
Great Britain and Ireland called England, the Dominion of Wales, and the
Town of Berwick upon Tweed, during the term of fourteen years therein
mentioned, our Invention of "A MODE OF HEATING SUCH PANS, VATS, CISTERNS,
AND OTHER VESSELS AS ARE REQUIRED TO BE HEATED BY FIRE AND USED FOR WORKING
STEAM ENGINES, AND IN THE BUSINESS OF A CALICO PRINTER, DYER, BREWER, PAPER
MAKER, BLEACHER, SALT MAKER, TANNER, AND OTHER SUCH LIKE TRADES, BY WHICH
INVENTION MUCH EXPENCE WILL BE SAVED NOT ONLY IN THE FUEL TO BE USED IN THE
HEATING SUCH VESSELS, BUT ALSO IN THE CONSTRUCTING THE VESSELS THEMSELVES;"
which Letters Patent contain a proviso requiring the said Robert Cross and
Thomas Southworth, by an instrument in writing under our hands and seals,
or under the hand and seal of one of us, to describe and ascertain the nature
of our said Invention, and in what manner the same is to be performed, and

page_text: cause the same 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.
NOW KNOW YE, that we, the said Robert Cross and Thomas Southworth,
in compliance with the said proviso, do hereby declare that the nature of our
said Invention, and the manner in which the same is to be performed, is parti-
cularly described as follows, that is to say :-
That instead of applying the fire to these boilers, &c., as heretofore in general
use, under the boiler, and the flues being on the outside, the fire is to be put
into the furnace in the inside of the boiler, and the flues also, which flues may
be carried once, twice, thrice, or more times round the inside of the boiler, and
surrounded with water, by which means a much greater surface of water is
applied to the fire, and much expence will be saved in the fuel, as also in the
erection of the boilers, particularly where used by dyers, printers, brewers, and
others using coppers. The boilers may be made of wood, stone, brick, cast or
wrought iron, or any other material waterproof, as may best serve the interest
of the person using the same, and less injury will be done to a vessel itself by
this mode of use than the general one by reason of the fire passing through
the cast or wrought iron furnace and flues. Soot and light ashes will of course
accumilate within the furnace and flues; but in order to clear away such
obstructions a cistern must be fixed above the boiler to hold as much water as
to fill the boiler when cleaned, &c., and the water must be admitted into the
chimney and flues by a valve or inlet fixed in the cistern, which is shewn in
the annexed Plans or Drawings, and explained by the references to the said
Plans or Drawings hereafter mentioned. References to the annexed Plans
or Drawings-Figure 1st, a, a, a, a, the boiler or cistern, made of cast or
wrought iron, or any other waterproof material; b, the furnace, made of cast
or wrought iron, in which the fire is contained, the fuel being admitted through
the hopper or furnace mouth at c; d, d, d, the flues or pipes through which
the flame passes one, two, three, or more times round the inside of the boiler,
all being surrounded with water up to the dotted lines above the pipes at e.
The flues may be made of cast or wrought iron. f, the chimney pipe, made of
cast iron, brick, or stone; g, a frame of timber or foundation of stone or brick,
on which the cast iron pillers h, h, are fixed (brick or stone will answer the
same purpose); i, the quadrant pinion, &c., for the purpose of letting out the
fire, or setting the grate bars to any angle at pleasure; j, a copper buoy, float-
ing on the surface of the water in the boiler, which, when the boiler wants
water, opens a valve in the cistern k, to feed the boiler through the pipe l;

buoy j. (This is to prevent the flues or pipes from receiving damage for want of
water.) r, r, the pillars to supply the water cistern m, n, supplied by the over-

In witness whereof, we, the said Robert Cross and Thomas Southworth,
have hereunto set our hands and seals, this Twenty-first day of January,
