AN IMPROVEMENT IN THE MANUFACTURE OF CAST TUBULAR BOILERS
Year: 1857

page_text: In the Matter of Letters Patent granted to HENRY ORMSON, of
Stanley Bridge, King's Road, Chelsea, Horticultural Builder and
Hot Water Apparatus Manufacturer, for the Invention of "AN
IMPROVEMENT IN THE MANUFACTURE OF CAST TUBULAR BOILERS," bearing
date the Nineteenth September, One thousand eight hundred and
fifty-seven, to which a Specification was duly filed.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
filed in the Great Seal Patent Office by the said Henry Ormson,
pursuant to the Statutes in that case made and provided.
WHEREAS the claim as made in the said Specification is too wide and
does not ascertain with sufficient precision the nature of my Invention, in
consequence whereof I, the said Henry Ormson, wish to disclaim and alter, by
a Memorandum of Alteration, and I do hereby disclaim and alter the said
Specification by altering and substituting for the words "and thus to form one
casting" at page 3, lines 3 and 4, the following words "so that the junctions
"exposed to the fire are cast with the tubes, as herein-after described, and
"shown in the Drawings;" and at page 4, line 7, by altering and sub-
stituting for the words "such as is above described in one piece," the words
"in the manner herein-before described, and shown in the Drawings."
.
And the said Specification, when amended as proposed by me by Disclaimer
and Memorandum of Alteration, will read as follows:-

page_text: NOW KNOW YE, that I, the said Henry Ormson, do hereby declare
the nature of the 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 thereof, that is to say:-
This Invention has for its object an improvement in the manufacture of cast-
iron tubular boilers, and is applicable to boilers used for the circulating of hot
water for heating horticultural and other buildings, and consists in causing
the upright tubes and the lower hollow ring (which connects tlie tubes together
at their lower ends) to be all cast at one time, so that the junctions exposed
to the fire are cast with the tubes, as herein-after described, and shown in the
Drawing. The upper ends of the tubes have also part of the hollow ring
which forms the upper water space cast with them. The lower hollow ring
is cast with one or more projecting sockets to receive the ends of the return
pipes. That portion of the upper hollow ring which is cast with the tubes is
suitably formed for receiving another casting, which is formed with a hopper
for receiving the fuel, also an outlet for the passage of smoke and products
from the fire, also with one or more sockets for receiving the ends of the flow
pipes. The tubes at one part of the lower end of the boiler.do not descend
so low down as the others, and the lower hollow ring is formed at this part in
such manner as to present an opening or doorway through to admit of the fire
on the interior of the boiler being readily got at.
Having thus stated the nature of my said Invention, I will proceed more
fully to described the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a cast-iron boiler made according to my Invention, the
lower part being in section; Figure 2 shews a view of the same boiler taken
at right angles to the view shewn in the previous Figure; and Figure 8 shews
a horizontal section. The lower hollow ring a, together with the tubes b, and
the upper hollow or trough-like ring c, and all cast in one piece. When the
casting has been made, the internal cores on which the tubes b and the core
on which hollow ring a have been cast are removed through the tubes 6 and
through the hollow trough-like ring c. The lower hollow ring a is cast with a
branch a', through which parts of the cores used may be removed. The upper
or hollow ring c is formed in a suitable manner to receive and have fixed
therein a cover, which is fixed and rendered water-tight by iron, cement, or
otherwise. This cover has formed thereon one or more sockets d, for flow
pipes, and through the cover there is an opening for feeding the fire. In some
boilers some of the tubes do not descend so low as the others, in order to

page_text: present an opening to get at the fire, in which case the lower hollow ring a
would be formed with bends accordingly; but I prefer that the fire-bars should
be sufficiently below the lower hollow ring a without having any bends therein.
In the arrangement shewn in the Drawing the fire-bars e, e, e, e, are cast
tubes, connected by the hollow castings e¹, e, which are cast in one casting
with the tubes e, e, as is shewn, and such castings e¹, e', are made with
sockets e, e, for a return pipe or pipes, and with a socket e³, to receive the
end of the branch a' of the boiler. The fire is made on the hollow tubes e, e,
and the return water passes through such tubes e, and then ascends into the
hollow ring a and tubes b, b.
I have not thought it necessary to shew the brickwork setting or the flues,
as the same may be varied according to the judgment of the workman.
I would remark that the form of the parts a, b, c, may be varied; but what
I claim is the casting a boiler in the manner herein-before described, and
shewn in the Drawing.
In witness whereof, I, the said Henry Orinson, have hereunto set my
hand and seal, the Fourteenth day of July, in the year of our Lord
One thousand eight hundred and sixty-three.
Signed, sealed, and delivered by
the said Henry Ormson, in
the presence of
THOS. STOCK,

HENRY ORMSON. (L.B.)
I hereby grant my fiat, giving leave to the above-named Henry Ormson to
file in the Great Seal Patent Office, with the Specification to which the same
relates, the above written Disclaimer and Memorandum of Alteration, dated
this First day of September, One thousand eight hundred and sixty-three.

for the Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF CAST
TUBULAR BOLLERS."
Sealed the 16th March 1858, and dated the 19th September 1857..
PROVISIONAL SPECIFICATION left by the said Henry Ormson at the
Office of the Commissioners of Patents, with his Petition, on the
19th September 1857.
I, HENRY ORMSON, of Stanley Bridge, King's Road, Chelsea, Horticultural
Builder and Hot Water Apparatus Manufacturer, do hereby declare the
nature of the Invention for "AN IMPROVEMENT IN THE MANUFACTURE OF CAST
TUBULAR BOILERS," to be as follows :-
.
This Invention has for its object an improvement in the manufacture of cast
tubular boilers, and is applicable to boilers used for the circulating hot water
for heating horticultural and other buildings, and consists in causing the
upright tubes and the lower hollow ring (which connects the tubes together at
their lower ends) to be all cast at one time, and this to form one casting. The
upper ends of the tubes. have also part of the hollow ring which forms the
upper water space cast with them. The lower hollow ring is cast with one or
more projecting sockets to receive the ends of the return pipes. That portion
of the upper hollow ring which is cast with the tubes is suitably formed for
receiving, another casting, which is formed with a hopper for receiving the

page_text: fuel, also an outlet for the passage of smoke and products from the fire, also
with one or more sockets for receiving the ends of the flow pipes. The tubes
at one part of the lower end of the boiler do not descend so low down as the
others, and the lower hollow ring is formed at this part in such manner as to
present an opening or doorway through to admit of the fire on the interior of
the boiler being readily got at.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Ormson in the Great Seal Patent Office on the
18th March 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ORNSON, of Stanley Bridge, King's Road, Chelsea, Horticultural Builder and
Hot Water Apparatus Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Ormson, Her special licence that I, the said Henry 'Ormson, my
executors, administrators, and assigns, or such others as I, the said Henry
Orinson, 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 "AN IMPROVEMENT IN
THE MANUFACTURE OF CAST TUBULAR BOILERS," upon the condition (amongst
others) that I, the said Henry Ormson, 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 J, the said Henry Ormson, do hereby declare the
nature of the said Invention, and in what mauner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object an improvement in the manufacture of
cast iron tubular boilers, and is applicable to boilers used for the circulating of

page_text: hot water for heating horticultural and other buildings, and consists in causing
the upright tubes and the lower hollow ring (which connects the tubes
together at their lower ends) to be all cast at one time, and thus to form one
casting. The upper ends of the tubes have also part of the hollow ring which
forms the upper water space cast with them. The lower hollow ring is cast
with one or more projecting sockets to receive the ends of the return pipes.
That portion of the upper hollow ring which is cast with the tubes. is suitably
formed for receiving another casting, which is formed with a hopper for
receiving the fuel, also an outlet for the passage of smoke and products from
the fire, also with one or more sockets for receiving the ends of the flow pipes.
The tubes at one part of the lower end of the boiler do not descend so low
down as the others, and the lower hollow ring is formed at this part in such
manner as to present an opening or doorway through to admit of the fire on
the interior of the boiler being readily got at.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a cast-iron boiler made according to my Invention, the
lower part being in section; Figure 2 shews a view of the same boiler, taken
at right angles to the view shewn in the previous Figure; and Figure 3 shews
a horizontal section. The lower hollow ring a, together with the tubes 6 and
the upper hollow or trough-like ring c, are all cast in one piece. When the
casting has been made, the internal cores on which the tubes 6 and the core on
which hollow ring a have been cast are removed through the tubes 6 and
through the hollow trough-like ring c. The lower hollow ring a is cast with a
branch a', through which parts of the cores used may be removed. The upper
or hollow ring c is formed in a suitable manner to receive and have fixed
therein a cover, which is fixed and rendered water-tight by iron cement or
O otherwise. This cover has formed thereon one or more sockets d for flow
pipes, and through the cover there is an opening for feeding the fire. In some
boilers some of the tubes do not descend so low as the others, in order to
present an opening to get at the fire, in which case the lower hollow ring a
would be formed with bends accordingly; but I prefer that the fire-bars should
5 be sufficiently below the lower hollow ring without having any bends
therein. In the arrangement shewn in the Drawing the fire-bars e, e, e, e, are
cast tubes, connected by the hollow castings e, e¹, which are cast in one casting
with the tubes e, e, as is shewn, and such castings e', e', are made with
sockets e, e, for a return pipe or pipes, and with a socket e³ to receive the end

page_text: of the branch a' of the boiler.. The fire is made on the hollow tubes e, e, and
the return water passes through such tubes e.and then ascends into the hollow
ring a and tubes b, b.
I have not thought it necessary to shew the brickwork setting or the flues,
as the same may be varied according to the judgment of the workman.
I would remark that the form of the parts a, b, c, may be varied; but what
I claim is, the casting à boiler such as is above described; in one piece.
In witness whereof, I, the said 'Henry Orimson, have hereunto set my
hand and seal, this Eighteenth day of March, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
FRANCIS HARRIS.
