Year: 1871

page_text: LETTERS PATENT to George Arthur Fernley, of Stockport, in the
County of Chester, Cotton Spinner, for the Invention of "IM-
PROVEMENTS IN STEAM BOILERS."
وو
Scaled the 27th June 1871, and dated the 3rd January 1871.
PROVISIONAL SPECIFICATION left by the said George Arthur Fernley
at the Office of the Commissioners of Patents, with his Petition,.
on the 3rd January 1871.
I, GEORGE ARTHUR FERNLEY, of Stockport, in the County of Chester,
Cotton Spinner, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN STEAM BOILERS," to be as follows:-
:-
My Invention consists in a peculiar arrangement of flues applicable
chicfly to those steam boilers which are on what is called the Butterley
principle. In these boilers, as is well known, the fire-bars are placed.
across the whole width of the boiler and deliver the products of com--
bustion to a longitudinal flue or flues.
According to my Invention I cause these flues communicate at
their further ends with another flue or flues which return through.the.

page_text: boiler towards the front end thereof at which situation they dip through
the shell into any ordinary flue or flues formed by the setting, or they
may be continued in any other suitable manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Arthur Fernley in the Great Seal Patent
Office on the 3rd July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
ARTHUR FERNLEY, of Stockport, in the County of Chester, Cotton
Spinner, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of January One thousand
eight hundred and seventy-one, in the thirty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me,
the said George Arthur Fernley, Her special license that I, the said
George Arthur Fernley, my executors, administrators, and assigns, or
such others as I, the said George Arthur Fernley, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN STEAM BOILERS," upon, the condition, amongst others, that I, the
said George Arthur Fernley, by an instrument in writing under my
hand and seal, should particularly describe. and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.

NOW KNOW YE, that I, the said George Arthur Fernley, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawings (that is
to say):
:-
My Invention consists in a peculiar arrangement of flues applicable
chiefly to those steam boilers which are constructed on what is commonly

page_text: called the Butterley principle. In these boilers as is well known the
fire-bars are placed across the whole width of the boiler and deliver
the products of combustion to a longitudinal flue or flues.
According to my Invention I cause these flues to communicate at
their further ends with another flue or flues, which return through the
boiler towards the front end thereof, at which situation they dip through
the shell into any ordinary flue or flues, or they may be continued in
in any other ordinary manner.
In the accompanying Drawing Fig. 1 represents a side view of the
boiler with the setting and fire-bars in section; Fig. 2 is a cross section
taken about the line A, B. Fig. 3 is an end view; and Fig. 4 a plan
of the setting. The main shell of the boiler is at a provided- at its front
end with the dome shaped part 6 of the ordinary Butterley boiler, and
beneath this are the fire-bars d made in two sets and extending across
the whole width. At c, d, e, are flucs situate at the rear, of the fire-place
and extending through the boiler, their further ends being open to a
chamber f, in connexion with which are tubular flues g, h, which extend
therefrom towards the front end of the boiler. At i, k, are short pipes
open to the tubular flues g, h, and dipping down so as to communicate
with a chamber / situate beneath the main part of the boiler, which is
supported by walls m forming the boundaries of the said chamber.
The first above-mentioned chamber f is arched at n, the said arch con-
stituting the top of the longitudinal chamber which communicates
with the main flue o leading to the chinney. At p is a short wall for
the purpose of carrying the inward ends of two dampers q, r, and by
means of which the draft may be regulated at pleasure. The plan
view, Fig. 4, it will be perceived is not drawn in the proper relative
position to Fig. 1, this was simply to gain space for shewing the main
fluc o.
The working of this improved boiler is as follows:- -The pro-
ducts of combustion passing from the fire-place d enter the flues c, d, e,
and flow from thence into the chamber f, against the ends of which
the boiler d is fixed; here they are arrested in their direct course, and
are caused to return towards the front end of the boiler through the
tubular flues g, h, which are closed at their ends t; as therefore the said
products cannot proceed further in that direction they pass downward
through the short tubes i, k, into the longitudinal chamber ; here
their course becomes divided, portions thereof passing along the side

page_text: flues u, v, the whole uniting in the main flue o after having passed the
dampers g, r.
Having thus described and ascertained the nature of my said Inven-
tion and the manner in which the same is to be performed, I would
remark that although the Drawing shews' two flues g, h, more or less
may be employed, that which I claim as secured to me under the above
in part recited Letters Patent, and as applied to steam boilers of the
aforesaid description being the use of a flue or flues or tubes bringing:
the products of combustion from the back towards the front end of the
boiler and discharging the said products into another flue, such flue or
flues or tubes being illustrated at g, h, i, k.
In witness whereof, I, the said George Arthur Fernley, have here-
unto set my hand and seal, this First day of July, in the year
of our Lord One thousand eight hundred and seventy-one.
