CERTAIN IMPROVEMENTS IN BOLLERS OR STEAM GENERATORS
Year: 1867

page_text: LETTERS PATENT to Thomas Beeley, of Newton Moor, in the County
of Chester, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
BOLLERS OR STEAM GENERATORS."
Sealed the 30th August 1867, and dated the 5th March 1867.
PROVISIONAL SPECIFICATION left by the said Thomas Beeley at the
Office of the Commissioners of Patents, with his Petition, on the
5th March 1867.
I, THOMAS BEELEY, of Newton Moor, in the County of Chester, Engineer,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN BOILERS OR STEAM GENERATORS," to be as follows:-
The Invention relates principally to the description of boilers wherein two flues
are employed, and the improvements are designed for the purpose of obtaining a
greater amount of heating surface than hitherto, and therefore better generation
of steam, also for obtaining additional strength and durability, and also to
facilitate the cleaning of the interior of the boiler generally, and to effect the
cleaning of the flues and the exterior and some parts of the interior of the
tubes when the multitubular arrangement is adopted.
The improvements consist in combining the flues of such boilers (which I
prefer to make of solid welded rings of metal so as to dispense. with rivetted
joints) with an elliptical combustion chamber (detached from the sides of the
boiler), in which the flues terminate, the plates of such chamber being connected

page_text: together with and strengthened by the joint called the "flange seam joint,"
which has its bolts outside, and this elliptical chamber is further supported and
strengthened against collapse by the application of internal, vertical, or diagonal
tubes through which the boiler water circulates; the plates forming the flues
I also prefer to connect by the flange seam joint in an aunular form, and also
insure vertical or diagonal tubes for water in the flues. In the description
of boiler termed "multitubular" the tubes are employed in combination
with such said construction of flues and chamber, the lowest series of tubes
being made of larger diameter than usual, and the interior of the tubes are
fitted with a series of scrapers to remove soot and incrustation, baving an
alternating reciprocating movement effected by means of a handle outside,
which arrangement may also be applied to the ordinary smaller diameter tubes
for the same purpose. In some instances these lower tubes may be entirely
removed, in which case the cleaning of the outsides of the tubes may be readily
effected, access beneath them being obtained by means of a "manhole "
provided or introduced at the back of the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Beeley in the Great Seal Patent Office on the
4th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BEELEY, of Newton Moor, in the County of Chester, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Beeley, Her special licence that I, the said Thomas Beeley,
my executors, administrators, and assigns, or such others as I, the said Thomas
Beeley, 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 "CERTAIN IMPROVEMENTS
IN BOILERS OR STEAM GENERATORS," upon the condition (amongst others) that I,
the said Thomas Beeley, my executors 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

page_text: 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Beeley, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The Invention relates principally to the description of. boilers. wherein two
flues are employed, in combination with an elliptical combustion chamber in
which the flues terminate, and consists in connecting together the plates
forming the flues and also the plates forming the combustion chamber, by means
of the joint known as the "flange seam joint,". and also introducing into the
flues and elliptical chamber vertical or diagonal tubes to obtain a greater
heating surface and a better circulation of the water in the boiler. I prefer
to make the plates forming the flues and elliptical combustion chamber in the
form of solid welded rings, so as to dispense with riveted joints longitudinally.
The peculiar feature of the description of boiler termed multitubular, where
the tubes are employed in combination with such said construction of flues and
chamber, is the ready access given for the purpose of cleaning the tubes, and
the lower half of the boiler by the insertion of two manholes, one at the front
and below the flues and the other at the back end and below the tubes, and I
make the lower rows of tubes of larger diameter than usual.
In order that my Invention may be more clearly understood, I have annexed
a Drawing hereto of which the following is a description.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a sectional elevation of a boiler wherein my improvements are
embodied; Fig. 2 is a sectional plan of the same; Fig. 3 is a view of the
front end; and Fig. 4 is a cross section through the tubes. The same letters
refer to corresponding parts in all the Figures.
A is the boiler; B, B, the flues made with the flange seam joints C, C, and
the vertical or diagonal tubes D, D; E, is the combustion chamber with flange
seam joints F, F, and vertical or diagonal tubes G, G; H, H, are the tubes,
the bottom rows of which are made of larger diameter than the others as shown
at I, I; K, K, are manholes, one at either end of the boiler, by which access
may be had for the purpose of cleaning the lower part.
Fig. 5 is a cross section; Fig. 6, shews the flange joint; Fig. 7 is a back
end view.
Having thus described generally the nature of my Invention, I would

page_text: remark that I am aware that it is not new to make a boiler having its interior
flues or tubes terminating in an elliptical combustion chamber, and I am also
aware that these flues and the combustion chamber have been made with the
flange seam joint; but this plan, although having the advantage of the strength
of the flange seam joint, has not the extra heating surface and power of creating
the circulation of the water in the boiler which is possessed by the internal,
vertical, or diagonal tubes. I am also aware that vertical and diagonal tubes
have been adopted in the flues and combustion chambers of this class of
boilers, but in this case, although the boiler possesses a great heating surface,
and affords great facilities for the circulation of the water, the flues and con-
bustion chamber do not possess the same strength that would be imparted to
them by the flange seam joint.
What I claim, therefore, as my Invention is, the combination of the flange
seam joint and the vertical or diagonal tubes in the internal flues and com-
bustion chambers of these boilers, whereby I obtain a maximum of strength,
and also a maximum of heating surface.
I also claim making the bottom rows of tubes in a multitubular boiler of
larger diameter than the others as the lower tubes are most liable to fill with
soot.
In witness whereof, I, the said Thomas Beeley, have hereunto set my
hand and seal, this Third day of September, in the year of our Lord
One thousand eight hundred and sixty-seven.
