Year: 1806

page_text: CAPARN'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CAPARN, of Leicester, in the County of Leicester, Brazier, send greeting..
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent, under the Great Seal of His United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Thirtieth day of October,
in the forty-seventh year of His reign, give and grant unto me, the said James
Caparn, my executors, administrators, and assigns, His especial licence that I,
the said James Caparn, my executors, administrators, and assigns, should and
lawfully might, during the term of years therein mentioned, make, use, exercise,
and vend within England, Wales, and the Town of Berwick upon Tweed, my
Invention of "A MACHINE FOR DISCHARGING SMOKE FROM SMOKING CHIMNIES," in
which said Letters Patent there is contained a proviso obliging me, the said
James Caparn, 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 to be 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, will more fully and
at large appear.
NOW KNOW YE, that in compliance with .the said proviso, I, the said
James Caparn, do hereby declare that my said "Invention is described in the
Drawings delineated in the margin of these presents, and by the .description
thereof herein-after particularly set forth (that is to say) :-
This machine (which I denominate "Caparn's smoke disperser," and have
invented for the prevention and cure of smoky chimneys) is to be placed on
the top of the chimney over the vent or orifice, and secured thereto by brick-
work or by any other method which may be deemed expedient. The funnel

page_text: of the chimney should be cleared from all contractions or other obstructions
which might impede the smoke in its passage into the body of the machine.
The current through the chimney gives a rotary horizontal motion to the flyers
or vans at the top of the machine, which thereby disperse the smoke, and
prevent the action of the atmosphere from returning it into the funnell of the
chimney. The machine and its several parts are represented in the Drawings
delineated in the margin of these presents. N° 1 represents the internal
structure of the body of the machine; N° 2, and 2 are bars crossing cach
other rivetted to the sides and supporting the upright spindle, No 4, which
is encircled by the hollow barrel or cylinder, N° 3, which is open at the
upper end, and screwed at the bottom to the base, from which the spindle.
N° 4 arises, and is intended to contain oil for facilitating the motion of the
vans or flyers. This barrel must be made large enough to admit the hollow
cylinder No 6, which contains a female centre to run or turn on the spindlo
N° 4. The-Figure N° 5 represents the cap or top of the machine, and consists
of a set of vans or flyers fastened at their upper extremities to the upper end
of the cylinder N° 6, and rivetted at the bottom to a circular rim of metal.
N° 7 represents the external appearance of the whole machine when put
together and complete.for use, the size of which must be in proportion to the
funnel of the chimney whereon it is to be placed. The body or external case of
the machine, and also the vans or flyers.and the rim to which the same are
rivetted, may be made of iron, copper, or tin. The cross bars may be made of
iron, and the spindle of steel or iron faced with steel hardened at the point,
working in the female centre. The female centre may also be made of steel
or iron faced with steel hardened at the part receiving the spindle, and the
two cylinders may be made of iron, cast iron, copper, or tin.
In witness whereof, I, the said James Caparn, have hereunto set my
hand and seal, this Twenty-seventh day of November, in the year of
our Lord One thousand eight hundred and six.
Signed, sealed, and delivered by
the above-named James
Caparn (having been first
--duly stamped) in the pre-
sence of us,
J' BARNES,
