page_text: FENNER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FENNER, late of Bushell Rents, Wapping, in the County of Middlesex, but
now of No. 11, Lower Fitzroy Place, New Road, in the said County,
Carpenter, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Sixth day of May, in the seventh year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
William Fenner, His especial licence that I, the said William Fenner, my
exors, admors, and assigns, or such others as I, the said William Fenner, my
exors, adiñors, or assigns, should at any time agree with, and no others, from
time to time and at all times 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 "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CURING SMOKEY AND CLEANSING FOUL
CHIMNEYS;" in which said Letters Patent is contained a proviso obliging me,
the said William Fenner, 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 same, referenco being thereunto had, will more fally and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Fenner, do hereby declare the nature of my said Invention to consist
in the application of a spiral pipe or flue to the upper part of an ordinary flue
or chimney, for the purpose of encreasing draft and giving a better direction
to the smoke, and also in means applied to cleaning the same; and in further
compliance with the said proviso, I, the said William Fenner, do hereby describe
the manner in which my said Invention is to be performed by the following
description thereof, reference being had to the Drawing annexed, and to the
figures and letters marked thereon (that is to say) :-
DESCRIPTION OF THE DRAWING.
Fig. 1 represents the section of a chimney with one of my said spiral pipes
or flues at its upper part. A is the said spiral pipe, make of copper or other
suitable material; and B, B, are two joints, the upper joint fitting over the
joint next below it, and fastening with a stud and slot, like a bayonet stop.
These joints are used for the purpose of taking the pipe asunder to clean it.
The spiral pipe is furnished with a flange D, D, at its lower end, which must
of course be suited to the top of whatever flue it has to rest upon, and upon it
is to be bedded in mortar, or secured in any other more convenient way, as
circumstances may suggest. Fig. 2 represents another application of my said
Invention, shewing the spiral pipe when it is inserted within the upper part of
a chimney, and also shewing the apparatus which must then be used for clean-
ing the same. A is the spiral pipe. It will be observed in this Drawing that
the brickwork round the spiral pipe is much less in thickness than the brick-
work of the strait or ordinary part of the fluo below. C, C, C, are three
sliding bolts moving in cases or hollow cylinders, which it will be seen are
built in the wall, and the object of these bolts is to tap against the spiral pipes
when they are gently struck with a hammer from the outside of the chimney,
in order to shake down the soot which may from time to time collect in the
spiral pipe. It will be seen that thero are small extra pieces of metal brazed
on to the pipe for the bolts to strike on. This operation will be greatly
assisted if the soot bo previously burned from below, a process which, where
the spiral pipe is used, would not be attended with any danger, since the soot
will thereby be prevented from accumulating.
Now whereas I claim as my Invention a spiral pipe as aforesaid, applied in
any way to the upper part of a chimney or flue, for the purpose aforesaid, and
also the bolts herein-beforo described for cleaning the same; and such my
Invention being, to the best of my knowledge and belief, entirely new and
never before used within that part of Iliad Majesty's United Kingdom of

page_text: Great Britain and Ireland called England, His Dominion of Wales, or Town
of Berwick upon Tweed, I do hereby declare this to be my Specification of
the same, and that I do verily believe this my said Specification doth comply
in all respects, fully and without reserve or disguise, with the proviso in the
said herein-before in part recited Letters Patent contained. Wherefore I
hereby claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said William Fenner, have hereunto set my
hand and seal, this Sixth day of November, in the year of our Lord
One thousand eight hundred and twenty-six.
(L.B.) W FENNER.
AND BE IT REMEMBERED, that on the Sixth day of November, in the
year of our Lord 1826, the aforesaid William Fenner came before our said
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Inrolled the Sixth day of November, in the year of our Lord One thou-
