Year: 1866

page_text: LETTERS PATENT to Daniel Adamson, of the Newton Moor Iron Works,
Hyde, near the City of Manchester, Engineer, for the Invention of
"IMPROVEMENTS IN VERTICAL STEAM BOILERS FOR MARINE AND OTHER
PURPOSES."
Sealed the 13th July 1866, and dated the 18th January 1866.
PROVISIONAL SPECIFICATION left by the said Daniel Adamson at the
Office of the Commissioners of Patents, with his Petition, on the 18th
January 1866.
I, DANIEL ADAMSON, of the Newton Moor Iron Works, Hyde, near the
City of Manchester, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN VERTICAL STEAM BOLLERS FOR MARINE AND
OTHER PURPOSES," to be as follows
My Invention consists in the combination of a series of vertical steam
boilers with internal fire boxes, which are arranged so as to economise space and
to increase the strength and evaporating power in comparison with boilers of
the ordinary construction. Each vertical boiler consists of an outer shell or
casing of a cylindrical or other form, inclosing the fire-grate and ash-pit; to
the roof of the fire box are secured the lower ends of the tubes or flues, the
upper ends of which are secured to the top plate of the boiler; a water buffle
plate is or may be introduced to prevent the displacement of the water. In
order to prevent the corrosion of the tubes or flues in the steam space of the
boiler, I cause that part thereof to be enamelled with glass or other vitrious

page_text: substance. The products of combustion from the series of boilers are collected
into one or more chimneys, and the steam from the boilers is collected into
one or more main steam pipes or domes, but each boiler may be disconnected
by dampers and valves from the chimney and main steam pipe, so that each
portion of the compound boiler may be cleaned or repaired without interfering
with the working of the remainder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Daniel Adamson in the Great Seal Patent Office on the
18th July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
ADAMSON, of the Newton Moor Iron Works, Hyde, near the City of Man-
chester, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Daniel Adamson, Her special license that I, the said Daniel Adamson,
my executors, administrators, and assigns, or such others as I, the said Daniel
Adamson, 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' VERTICAL
STEAM BOILERS FOR MARINE AND OTHER PURPOSES," upon the condition (amongst
others) that I, the said Daniel Adamson, 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 Daniel Adamson, 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 (that is to say):-
My Invention consists in the combination of a series of vertical steam boilers
with internal fire-boxes, which are arranged so as to economise space and

page_text: increase the strength and evaporating power. Each vertical boiler consists of
an outer shell or casing of a cylindrical or other form inclosing the fire-grate
and ash-pit. To the roof of the fire box are secured the lower ends of the
tubes or flues, the upper ends of which are secured to the top plate of the
boiler. A water baffle plate is or may be introduced to prevent the displace-
ment of the water. In order to prevent the corrosion of the tubes or flues in
the steam space of the boiler I cause that part thereof to be enamelled with
glass or other vitrious substance. The products of combustion from the series
of boilers are collected into one or more chimneys, and the steam from -the
boilers is collected into one or more main steam pipes or domes, but each
boiler may be disconnected by dampers and valves from the chimney and
main steam pipe, so that each portion of the compound boiler may be cleaned
or repaired without interfering with the working of the remainder.
And in order that my Invention may be more fully understood I will
proceed to describe the accompanying two Sheets of Drawings, reference.
being had to the figures and letters marked thereon.
On Sheet 1, Figure 1 is an elevation, partly in section, of a vertical steam
boiler constructed according to my improvements; Figure 2 is a plan in
section through the fire boxes; and Figure 3 is a plan of the entire boiler.
a and b are the outer shells or casings of the two portions of the compound
boiler, each shell or casing consists of two or more plates welded into hoops
to dispense with the vertical seams and rivets, and the holes for the circular
seams and rivets are drilled, and the hoops are then rivetted together, as
heretofore practised by me. Each shell or casing contains a fire box marked
respectively a and b, the casings a and b are secured to the ash-pits a³ and ³,
and each fire box contains a fire-grate a³ and 6%. The fire boxes may be
placed eccentrically in the shells a and b for the purpose of giving more
facilities for internal cleaning and repairs. To the roof of each fire box are
secured the lower ends of the tubes or flues c and d, the upper ends of which
are secured to the top plates c¹ and d₁ of the casings; c is a baffle plate in
the boiler and a similar baffle plate is placed in the boiler d; the object of
these baffle plates is to prevent the displacement of the water when the boilers
are under steam. And in order to prevent the corrosion of the tubes or flues
in the steam space of the boiler I cause that part thereof to be enamelled,
with glass or other vitrious substance. The annular tube e is perforated to
distribute the feed water in the boiler as described in the Specification,
of Letters Patent granted to me in conjunction with Levi Leigh, on the
Twentieth day of June, One thousand eight hundred and sixty-two, No. 1820.
The tube e is coupled to the ordinary water supply pipe; the annular pipe e¹
a

page_text: is also perforated and coupled to the ordinary blowing-off apparatus, the pipe e
may have a V-trough on the top to collect the sedimentary deposit. The
products of combustion from the two fire-grates unite in the smoke box g, and
pass to the chimney f. The chimney is fixed to the chimney base or smoke
box g, which connects the upper ends of the two portions of the boiler, and
large doors h are provided in the said smokė box for the convenience of cleaning
out the sets of tubes or flues c and d, a damper is placed in the smoke box
to intercept the products of combustion from any one portion of the compound
boiler to the chimney when the other is under repair, or having the tubes
brushed out. The steam spaces of the boilers à and b are connected by the
pipes, which unite in the pipe , by which the steam is conveyed to the
engine, and at each side of the pipe is a shut-off valve 2, by means of which
each portion of the compound boiler can be disconnected from the other when
requisite for repairs or for other purposes. The safety valves are contained
in the boxes j,, and the steam blown off is conveyed away by the pipe j'.
The water gauges and blow-off cocks, which are not shewn in the Drawing,
are made as usual.
Figures 4, 5, and 6, are three views of another compound boiler constructed
according to my improved arrangements, only one outer shell or casing a is
required, and the fire boxes a¹ and are divided by a partition or midfeather
provided with stays k and tubes 1, the latter of which allow the products of
combustion to circulate from one fire box to the other. The tubes or flués
c and d unite in the smoke box g, and the chimney f is placed to one side of
the boiler as shewn in Figure 6 to give room for the doors h.
Figures 7, 8, and 9 are three views of another modification of my improved
compound vertical steam boilers. In this arrangement a and b'are the two
outer shells or casings, each of which contains four fire boxes and four sets of
tubes or flues, each of which can be 'cleaned independently of the others by
opening the doors h. The smoke box g is also divided into four chambers by
partitions with moveable dampers. The steam froin both portions of the
boiler is connected in the 'domes m, and conveyed to the engine by the pipes
2 and as before described.
Figures 10, 11 and 12, are three views of another of my improved compound
vertical steam boilers. In this arrangement the fire boxes a unite in a circular
combustion chamber k, through the centre of which is the pipe k to allow the
water to circulate. The tubes c form the communication between the con-
bustion chamber k and the smoke box 'g.
On Sheet 2, Figures 13 and 14 are 'an élévation and plan of another modi-
fication of my Ingention, the four separate portions of this compound boiler

page_text: are similar to the two shown in Figures 1, 2, and 3, and the products of
combustion are all united in a single smoke box 9, to which is fixed the
chimney f. The steam pipes i are also united to the pipe ; each portion of
this compound boiler can be disconnected from the others as above described.
Figures 15, 16, and 17 are three views of one portion of a compound boiler
constructed according to a modification of my Invention; in these views the
tubes c terminate in the smoke box g, placed within the external casing a, by
which arrangement the tubes are shortened.
I wish to observe that many other modifications of my improved compound
vertical steam boilers might be given, but the foregoing are sufficient to illus-
trate the nature and particulars of my Invention.
I would also remark that vertical steam boilers with tubes or flues have
been in use for many years, I therefore make no claim to such boilers
individually; but what I do claim is, the general combinations and arrange-
ments of compound vertical steam boilers as shewn and described.
And, secondly, the application of enamel to that part of boiler tubes that is
exposed to the action of steam as described.
In witness whereof, I, the said Daniel Adamson, have hereunto set my
hand and seal, this Fourteenth day of July One thousand eight hundred
and sixty-six.
DANIEL ADAMSON. (L.S.)
