AN IMPROVED FUEL
Year: 1800

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
DAVEY, of the Parish of Christchurch, in the County of Surry, Coal
Merchant, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twentieth day of May, in the fortieth year of His
reign, give and grant unto me, the said Peter Davey, His especial licence that
I, the said Peter Davey, during the term of years therein mentioned, should
and lawfully might use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "AN IMPROVED FUEL;" in
which said 'Letters Patent there is contained a proviso obliging me, the said
Peter Davey, by an instrument in writing under my hand and seal, to cause a
particular description of the nature of my said Invention, and in what manner
the same is performed, to be inrolled in His Majesty's High Court of Chancery
within one calendar month 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
Peter Davey, do hereby declare this my method of Making Improved
Fuel is by coking or in part coking or cementing the following or any
other materials which are capable of being united with sea coal by being
coked or in part coked or cemented by fire in a kiln, oven, or furnace, or in
any other way by which heat can be conveyed, so as to char or coke, or in
part to char or coke, so as to cement mixt materials, leaving a sufficient
substance in them to answer many of the various purposes in which it is
necessary or desirable to avoid the inconveniences of smoak or the smell of
sulphur; that is to say, I take the small of the best or other sea coal, to
which I put charcoal or wood, breese, turf, tan, sawdust, cork cuttings, peat, or
other inflammable ingredient or ingredients, which ingredient or ingredients
is or are proportioned in quantity to the quality of the sea coal with which it
is mixt. The substance or substances mixt with the sea coal are likewise
proportioned according to the purposes for which the fuel is required. For
example, if it is designed for large fires, for register or other stoves with a
powerful draft, a greater proportion of sea coal or the most durable materials is
used; if to burn in small fires, as in bed rooms, or instead of charcoal, where
there is but little draft, a greater proportion of the lighter materials is neces-
sary. The materials are then well mixed and put into kilns, ovens, or other
furnaces, either dry or moistened, and by means of dampers, slides, vent or air
holes, or other contrivances, the heat is so regulated as to be equal to cementing
the materials without destroying them. The degree of heat necessary to effect
my purpose, as well as the time required for cementing any given quantity, is
known by means of vent or air holes or other contrivances, and by the colour
and state of the steam, smoak, or vapour which proceeds from the materials.
The heat and time must not only be well suited to the quantity cemented at
one process, but likewise to the quality or strength of the sea coal, and the
proportions of the different materials, and which proportions, as before
mentioned, are varied according to the purposes for which the fuel is
required.
In witness whereof, I, the said Peter Davey, have hereunto set my
hand and seal, this Nineteenth day of June, in the year of our Lord
One thousand night hundred
P. DAVEY. (L.S.)
