Year: 1865

page_text: LETTERS PATENT to Thomas Brown Jordan, of Milton Cottage, South.
Lambeth, in the County of Surrey, Mechanical Engineer, for the Inven-
tion of "GENERATING STEAM IN COMBINED VERTICAL CYLINDERS."
Sealed the 24th April 1866, and dated the 28th October 1865.
PROVISIONAL SPECIFICATION left by the said Thomas Brown Jordan
at the Office of the Commissioners of Patents, with his Petition, on
the 28th October 1865.
I, THOMAS BROWN JORDAN, of Milton Cottage, South Lambeth, in the
County of Surrey, Mechanical Engineer, do hereby declare the nature of
the said Invention for "GENERATING STEAM IN COMBINED VERTICAL CYLINDERS,'
to be as follows:-
cylinders of iron, steel, copper,
brazing, riveting, solid drawing,
These cylinders are fitted into
This Invention is a peculiar arrangement of
or other metal which can be made by welding,
or casting into cylinders open at both ends.
connecting rings or collars, which are also open at the ends, and have steam
and waterways cast through their opposite sides. In general I make each of

page_text: these cylinders. of sufficient size for a boiler of one-horse power.. The ends
of the cylinders are closed by cast-iron covers, which are held in place by
stay bolts passing through the centre of each cylinder and through the top and
bottom covers so as to tie these covers together and make a good steam-tight
joint against the ends of the connecting rings. These joints are made tight
by any of the usual means of making manhole or other steam joints, but I
prefer turning the metal surfaces in the lathe, so that the joint may be made.
perfect with great facility by using a very small quantity of putty or mastic,.
to admit of their being broken and remade as often as may be found requisite.
for cleaning the boiler..
The accompanying Drawing is a section of one cylinder or a boiler of one-
horse power, and in the ordinary practice a boiler of twenty or thirty horse.
power would consist of twenty or thirty such cylinders grouped together as
may be most convenient for the situation it is to occupy, and connected together
by the flanges of the connecting collars, and such additional coupling pieces
as may be required.. For the most part I make the cylinders nine inches
diameter and seven feet long, but I do not limit myself to any particular size,
because under some circumstances it is desirable to use tubes of half the
usual diameter, or of any other size. In, mounting these boilers I prefer setting
them in brickwork, as shown in the section, whenever that method is admissible,
but for all locomotive engines a water case must be used which would then
form a part of the boiler and be connected with the cylinders by the flanges
F, G. It is not requisite to specify the details of a water case, because it
does not form any part of my claim..
Referring to the section it will be seen that the cylinders are set vertically
between two walls, and resting by lower flanges of connecting rings on a cast-
iron bed plate or horse,, in which there are openings under each cylinder of
sufficient size to admit of the lower cover being removed through the cleansing
door D, so that by removal of the covers all parts of the boiler are com-
pletely thrown open for examination and cleaning.
The small arrows show the course of the flame and heated air passing from
the furnace, to which course it is restrained by the. stop plates a, b, c, d, e,
which also perform the office of thoroughly mixing the gases so that no
particle can escape through the flue without being brought in contact with
the surface of the boiler..

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BROWN JORDAN, of Milton Cottage, South Lambeth, in the County of Surrey,:
Mechanical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Brown Jordan, Her special licence that I, the said Thomas
Brown Jordan, my executors, administrators, and assigns, or such others
as I, the said Thomas Brown Jordan, 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
"GENERATING STEAM IN COMBINED VERTICAL CYLINDERS," upon the condition
(amongst others) that I; the said Thomas Brown Jordan, 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 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 Thomas Brown Jordan, 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 thereof, reference being had to the Drawings hereunto
annexed, that is to say -
This Invention is a peculiar arrangement of cylinders of iron, steel, copper,
or other metal, which can be made by welding, brazing, riveting, solid
drawing or casting into cylinders open at both ends. These cylinders aro
fitted into connecting rings or collars which are also open at the ends and
have steam and water ways cast through their opposite sides. In general I make
each of these cylinders of sufficient size for a boiler of one-horse power. The
ends of the cylinders are closed by cast-iron covers, which are held in place by
stay bolts passing through the centre of each cylinder and through the top and
:

page_text: bottom covers so as to tie these covers together and make a good steam-tight
joint against the ends of the connecting rings. These joints are made tight by
any of the usual means of making manhole or other steam joints, but I
prefer turning the metal surfaces in the lathe so that the joint may be made
perfect with great facility by using a very small quantity of putty or mastic, 'to
admit of their being broken and remade as often as may be found requisite for
cleaning the boiler.
Figure 1 of the accompanying Drawings is a vertical elevation, with the
brickwork in section, showing a set of vertical cylinders for generating steam,
arranged or combined according to my Invention; Figure 2 is a vertical
section of one of the cylinders detached; and Figure 3 is a horizontal section
through the line a, b, of Figure 1.
A is the brickwork which encloses the furnace and the space in which the
cylinders are arranged; B, 'B, are the cylinders, they are open at both
ends and are formed of iron, steel, copper, or other suitable metal; C, C, are
metal rings or collars, which are fitted to each end of the cylinders B; these
collars C are open at the top and bottom and are cast with openings at
opposite sides for the passage of water or of steam as the case may be; these
openings are 'flanged so as to admit of a series of the cylinders being connected
together as shewn; D, D, are cast-iron covers, which are fitted to the collars
C so as to close the upper and lower ends of the cylinders B, and are held in
place by stay bolts E, E, which pass through the top and bottom covers and
are secured by nuts F, F. In order to make the joints steam-tight I prefer,
as before mentioned, to turn the metal surfaces which are brought in contact
in a lathe so that a perfect joint is formed with the addition of a little putty
or mastic, and this admits of the parts being readily taken apart for the
purposes of cleaning or repair. The cylinders are arranged vertically in rows
between the walls of the furnace, the flanges of the lower rings C rest on
projecting ribs of a cast-iron bed plate G. Spaces are left between the ribs
of the bed plate below each cylinder, so as to admit of the lower-covers of the
cylinders being removed on opening the door H, and in this way the interior
of each cylinder may be cleaned and thoroughly examined. The cylinders
which are contiguous to each other are connected by the flanges of the rings or
collars C, C, the end cylinders in each row being connected one with the other by
the coupling pieces I, I, and the elbow pipes J, J, so that the water.passages and
also the steam passages of the whole series are in communication throughout;
K is the feed pipe; L, the steam pipe; M, the blow off; N, the safety valve;
and O, the guage; P, P, are stop plates arranged in the furnace, which serve
to conduct the flame and heated gaseous matters round the cylinders, and which

page_text: by checking the escape of the gases cause them to mix intimately, so that their
complete combustion is effected. The arrows indicate the circuitous course
which the stop plates P cause the products of combustion to take before they
escape into the flue Q. The number of these stop plates may be varied
according to the size and power of the boiler, larger boilers not requiring
so many on account of the greater breadth of flue between the enclosing
walls.
In adapting these cylinders or steam generators to locomotive engines,
they are enclosed in a water case, which thus forms a portion of the boiler,
and they are connected thereto by the flanges of the rings or collars C, C.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
Arranging and combining vertical cylinders for generating steam, sub-
stantially as herein-before described and represented in the accompanying
Drawings, such cylinders being terminated by or fitted into rings containing
steam and water ways, and being closed by covers held in place by stay rods,
all substantially as described.
In witness whereof, I, the said Thomas Brown Jordan, have hereunto
set my hand and seal, this Twenty-seventh day of April, One thousand
eight hundred and sixty-six.
