PROVISIONAL SPECIFICATION left by the said John Partington and
David Riley at the Office of the Commissioners of Patents, with
their Petition, on the 25th October 1872.
We, JOHN PARTINGTON, Boiler Maker, and DAVID RILEY, Manu-
facturer, both of Thornton Road, Bradford, in the County of York, do
hereby declare the nature of the said Invention for "A NEW OR IMPROVED
STEAM GENERATOR OR BOLLER," to be as follows, that is to say:-
Our Invention relates to making steam boilers with seven or more
wrought-iron tubes connected together by means of a series of conical
tubes fixed at angles; also in dividing the fire chambers or flues. For
this purpose we employ wrought-iron tubes of small diameters and place
the two first tubes at a suitable distance equal to the size of the fire-grate

page_text: required. The two next tubes are placed at a suitable height and
brought towards the centre. Two more tubes are placed at equal height
to the bottom tubes and at equal centres. The seventh tube is placed in
the centre and at a suitable height above the two top tubes. These
tubes are joined together by a series of conical tubes fixed at angles.
The feed water enters at the back end and into the two bottom tubes,
and passes from tube to tube by means of the conical tubes giving free
circulation to the water and steam. The steam chest or eighth tube is
fixed above the seventh tube, and joined by means of two parallel pipes
or tubes rivetted to the seventh tube. We may employ the seventh tube
as a steam chest; in that case we make the seventh tube larger in
diameter than the other tubes.
The front part of the boiler tubes are rivetted on cast-iron round
blocks having flanges, in which are fitted round doors securely bolted
These doors are for the purpose of cleaning out and repairing the

When the boiler is set on its seat the two bottom and top boiler tubes
touch or nearly touch the sides of the brickwork forming the flues.
The two centre tubes have near the top a fire-brick tile partition placed
the whole length of the tubes and closing all openings to the third set 2
of tubes and second chamber. On the top sides of the conical tubes,
and placed the whole length and sides of the boiler, are also fire-brick
tile partitions closing all communication between the inside or fire-place
of the boiler and side flues. The inside of the flues of the third set of
tubes are also closed by means of fire-brick tile partitions. The fire 2
from the combustible passes and acts first on the two sets of boiler tubes
and round the first series of conical tubes, passing through a back
chamber and forward to the third set of tubes and second chamber and
round the top conical tubes. From there it passes in front through two
openings on each side of the remaining sides of the boiler tubes and 3
conical tubes to the chimney flue.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PARTINGTON, Boiler Maker, and DAVID RILEY, Manufacturer, both of
Thornton Road, Bradford, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John Partington and David Riley,
Her special licence that we, the said John Partington and David Riley,
our executors, administrators, and assigns, or such others as we, the
said John Partington and David Riley, our 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 "A NEW OR IMPROVED STEAM GENERATOR OR BOILER,"
upon the condition (amongst others) that we, the said John Partington
and David Riley, our executors or administrators, by an instrument in
writing under our, 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 we, the said John Partington and David
Riley, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to
the Drawing hereto annexed and to the figures and letters marked
thereon, that is to say :-
The said Invention relates to making steam boilers with seven or more
wrought-iron tubes connected together by means of a series of conical
tuhoc fived of anclos also in
the fine abouch
T

page_text: this purpose we employ wrought-iron tubes of small diameter, and place
the two first tubes at a suitable distance apart equal to the size of the
fire-grate required. The two next tubes are placed at a suitable height
above the first tubes, and are brought towards the centre.
Two more
tubes are placed above the last tubes, but exactly over or at equal centres
with the bottom tubes. The seventh tube is placed in the centre and at
a suitable height above the two top tubes. These tubes are joined
together by a series of conical tubes fixed at angles. The feed water
enters at the back end and into the two bottom tubes, and passes from
tube to tube by means of the conical tubes, allowing free circulation to
the water and steam. The steam chest or eighth tube is fixed above the
seventh tube, and is joined to it by means of two parallel pipes or tubes.
We may employ the seventh tube as a steam chest. In that case we
make the seventh tube larger in diameter than the other tubes.
.
The front parts of the boiler tubes are rivetted on cast-iron round
blocks having flanges, in which are fitted round doors securely bolted on.
These doors are for the purpose of cleaning out and repairing the tubes
forming the boiler.
When the boiler is set on its seat the two bottom and top boiler tubes
touch or nearly touch the sides of the brickwork forming the flues. The
two centre tubes have near the top a fire-brick tile partition placed the
whole length of the tubes and closing all openings to the third set of
tubes and second chamber. On the top sides of the conical tubes and
placed the whole length and sides of the boiler are also fire-brick tile
partitions closing all communication between the inside or fire-place of
the boiler and side flues. The inside of the flues of the third set of
tubes is also closed by means of fire-brick tile partitions. The fire from
the fuel passes and acts first on the two sets of boiler tubes and round
the first series of conical tubes, passing through a back chamber and
forward to the third set of tubes and second chamber and round the top
conical tube. From thence it passes in front through two openings on
each side of the remaining sides of the boiler tubes and conical tubes to
the chimney flue.
We obtain by our system a large heating surface in a small space and
utilize the heat to great advantage; producing a great saving in fuel.
But in order to enable our improvements to be better understood we
will proceed to describe the same by reference to the accompanying

page_text: Drawing, in which Figure 1 represents a sectional side view of a steam
boiler; Figure 2 sectional side view and front view; and Figure 3. plan
of the same. Similar letters of reference are used to represent similar
parts.
A, A, are the iron tubes forming the bottom tubes of the boiler con-
nected by means of the conical tubes E with the next tubes B, which
are placed towards the centre. Near the top of the tubes B another set
of conical tubes F is fitted connecting the tubes B with the tubes C.
Another set of conical tubes G is also fitted to the tubes C connecting
them with the steam chest D. All the conical tubes are fixed at angles.
The feed water enters at the back of the tubes A, and passes from them
through the conical tubes E into the tubes B, and onwards through the
conical tubes F into the tubes C, and through the conical tubes G into
the steam chest D, giving free circulation to the water and steam.
We have shewn the seventh tube forming the steam chest, but we can
employ eight tubes as herein-before described. H, H, are the cast-iron
round blocks liaving flanges, in which are fitted the round doors I,
securely bolted on by the bolts J. K is the fire-brick tile partition
placed the whole length of the tubes and closing all openings to the
chamber L. The fire from the fuel is kept in the chamber M by means
of the fire-brick tile partitions K and N, and first acts on the tubes A,
conical tubes E, and tubes B, and passes, as shewn by the arrows
Figure 1, through the back chamber R into the chamber L, acting on
the conical tubes G, and on part of the tubes B and C, and on the water
contained in the steam chest D. This chamber L is also closed by the
fire-brick tile partitions K, O, and P. The fire coming forward passes
thence through the opening S into the side flues Q, and then into the
chimney flue. T, safety valves; U, stop valve; V, man hole.
Having thus described our improvements and the best means we are
acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shewn
and described, as the same may be varied without departing from the
peculiar character of the Invention; but what we do claim is,-
Firstly. Making steam boilers with seven or eight tubes connected
together by means of conical tubes set at angles substantially as described
and represented in the accompanying Drawing.

page_text: Secondly. Dividing the fire chambers or flues by means of fire-brick
tile partitions substantially as described and represented in the accom-
panying Drawing.
In witness whereof, we, the said John Partington and David Riley,
have hereto set our hands and seals, this Seventeenth day of
April, in the year of our Lord One thousand eight hundred and
seventy-three.
