IMPROVEMENTS IN THE SETTING OF AND IN MEANS OF CLEANSING STEAM BOILERS
Year: 1873

page_text: LETTERS PATENT to Louis Gooder, of Field Lane, Thorne's Lane,
Wakefield, in the County of York, Engineer, for the Invention of
"IMPROVEMENTS IN THE SETTING OF AND IN MEANS OF CLEANSING STEAM
BOILERS."
PROVISIONAL SPECIFICATION left by the said Louis Gooder at the
Office of the Commissioners of Patents, with his Petition, on the
8th May 1873.
I, LOUIS GOODER, of Field Lane, Thorne's Lane, Wakefield, in the
County of York, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE SETTING OF AND IN MEANS OF CLEANSING
STEAM BOILERS," to be as follows:-
-
This Invention relates to the setting or to the construction and
arrangement of the outside flues or passages for the circulation of the
heated gases arising from the combustion of fuel in such manner as to
obtain greater heating surface and afford. facilities for cleansing the
outside of the boiler, thereby to secure greater economy of fuel.
The side flues I construct so as to extend nearly to the crown of the
boiler, that is, nearly over the whole upper surface of the boiler, and the

page_text: under fiuo I construct wider than heretofore. By means of these
enlarged flues a greater heating surface is obtained or exposed to the
action of the heated gases. Also over the higher portion of these flues
are openings or apertures formed in the brickwork (closed by doors or
plates) for the purpose of affording facility for cleansing the outside of
the boiler either by a jet or jets of steam or by brushing or scraping
the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Gooder, in the Great Seal Patent Office on
the 8th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
GOODER, of Field Lane, Thorne's Lane, Wakefield, in the County of York,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of May, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Louis Gooder, Her special licence
that I, the said Louis Gooder, my executors, administrators, and
assigns, or such others as I, the said Louis Gooder, my executors, admi-
nistrators, 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 THE SETTING
OF AND IN MEANS OF CLEANSING STEAM BOILERS," upon the condition (amongst
others) that I, the said Louis Gooder, my exccutors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, 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 Louis Gooder, 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

page_text: say :-
This Invention relates to the setting or to the construction and
arrangement of the outside flues or passages for the circulation of the
heated gases arising from the combustion of fuel in such manner as to
obtain greater heating surface and afford facilities for cleansing the
outside of the boiler, thereby to secure greater economy of fuel.
The side flues I construct so as to extend nearly to the crown of the
boiler, that is nearly over the whole upper surface of the boiler, and the
under flue I construct wider than heretofore. By means of these enlarged
flues a greater heating surface is obtained or exposed to the action of
the heated gases. Also over the higher portion of these flues are
openings or apertures formed in the brickwork (closed by doors or plates)
for the purpose of affording facility for cleansing the outside of the boiler
cither by a jet or jets of steam or by brushing or scraping. the same.
Such being the nature and object of this my said Invention, I will
now proceed to describe the same, and in order that the Invention may
be clearly understood, I have hereunto annexed a Sheet of Drawings,
Fig. 1 of which is a cross vertical section and Fig. 2 a plan view.
A is the boiler; B, the setting or brickwork; C, C, are the side flues;
D is the under flue. Through the upper portions of the flues C, O, are
openings or apertures F, F, F, closed by doors or plates. The under side
of these doors have a projection or rib around them which is received
within a groove formed round the openings or apertures and filled with
sand to prevent the ingress of cold air, which doors or plates may be
opened or removed so as to facilitate cleansing the outside of the boiler
by a jet or jets of steam or by means of the brush M, or by scraping.
The soot or refuse will be removed from the bottom of the flues by rakes.
Having thus fully described the nature and object of this my said
Invention, together with the manner in which the same is to be or may
be performed or carried into practical effect, I would remark that I do
not claim separately the peculiar form of flues shewn in the Drawings,
but what I claim is,―
Firstly. The form and construction of flues in connection and com-
bination with apertures or openings formed therein as and for the
purpose herein fully described and illustrated.

page_text: Lastly. The use or employment of openings or apertures formed in
the flues of boilers and closed by doors or covered by plates for the
purpose herein set forth.
In witness whereof, I, the said Louis Gooder, have hereunto set
my hand and scal, this Fifth day of November, in the year
of our Lord One thousand eight hundred and seventy-three.
