Year: 1873

page_text: LETTERS PATENT to Georgo Rydill, of Grove House, Dewsbury, in the
County of York, for the Invention of “IMPROVEMENTS IN STEAM ENGINES
AND BOILERS."
Scaled the 15th April 1873, and dated the 24th February 1873.
PROVISIONAL SPECIFICATION left by the said George Rydill at the
Office of the Commissioners of Patents, with his Petition, on the
21th February 1873.
I, GEORGE RYDILL, of Grove House, Dewsbury, in the County of York,
do hereby declaro the nature of the said Invention for "IMPROVEMENTS IN
STEAM ENGINES AND BOILERS," to be as follows :—
My Invention of improvements relates to the working of sectional
steam boilers on land and sea, which sectional steam boilers aro named
in my Specification of December 28th 1872, No. 8938, and in my Speci-
fication of January 28th 1878, No. 329, and I further describe the

page_text: working arrangements of sectional boilers, showing how they may be
worked on railways.

This Invention of improvements is in the working of steam engines
and sectional boilers, which I describe as follows, and in order to make
my improvements clearly understood I will call a locomotive steam 5
engine and boiler attached to a train of carriages the first steam engine
and boiler, and my improvements in sectional locomotive engine and
boiler I call the second steam engine and boiler, the chimney being at
the front end of the second engine boiler :-The chimney of the first.
engine and boiler I dispense with or make up, and a tube or chamber is 1
fixed to the boiler at the smoke-box end of the first steam engine boiler.
The second sectional, steam engine and boiler, with its working parts, is
in every respect like the first steam engine and boiler, except that no
fire-box is in the second engino boiler, which boiler may contain the
same number of tubes as the first steam engine boiler, or it may contain 1
less tubes of larger diameter, or it may contain more tubes than the first,
engine boiler, which tubes may be brought up to the end of the second.
steam engine boiler. Projecting beyond the back end of the second
steam engine boiler is a tube or chamber, which is firmly secured to the
boiler of any required-length or diameter. Affixed to the front end of 2
the first steam engine boiler, projecting beyond the boiler or smoke box,
is a tube or chamber, being of any required length or diameter, which
extends and fits into the interior, or it may fit on to the exterior of the
tube or chamber of the second engine boiler in the form of a sliding tubo
of a telescope, which tube or tubes and chambers are made to fit, so that 2
they form a joint or union to resist the steam and the products of com-
bustion coming from the first steam engine and boiler. This joint, to
resist the smoke and products of combustion from the first engine and
boiler, I make with a spring packing, either in one spring or in spring
segments, so that in running round a curve the spring will give way. 3
The exhaust steam from the first steam engine and boiler cylinders is
discharged by the exhaust tube or tubes into a bent pipe or tube in the
form of an elbow, which faces the tubes of the second engine boiler, so
that the steam of those cylinders is discharged into the tubes or chambers.
which connect the first and second engines and boilers together, so that 8
the exhaust steam from the first engine cylinders passes along with the
products of combustion through the connecting tube or chamber of tho

page_text: tivo boilers, and through the boiler tubes of the second steam engine
boiler, heating the water and raising steam, so that when the heated
products of combustion, along with the exhaust steam from the first
engine cylinders reaches the front end of the second engine boiler, which
I call the smoke-box end, the products of combustion and the exhaust
steam from the first engine cylinders unites with the steam of the second
engino cylinders in passing up the chimney. The exhaust steam from¯
the second angine cylinders creates a strong draught through all the
tubes and up the chimney. In this manner the exhaust steam and
O products of combustion may be carried through any required number of
sectional boilers.
The two engines and boilers are coupled together, having spring
buffers, so that the engines and boilers give and tako, as also the spring
attached to the tubes and chambers, which spring is held back with
levers when the engine tubes and chambers are coupled together,
enabling curves to bo casily run over. By this arrangement several
engines and boilers may be attached together, or a second boiler may
bo fixed upon wheels for raising steam only, and coupled to the first
engine and boiler, and the exhaust steam from the first engine cylinders
.may be carried in pipes to the front end of the second boiler to create a
draught for the firo and products of combustion from the first 'engine
boiler.
I profer to place at the end of the exhaust pipo or pipes a funnel-
shaped or roso end, which rose and contains as many holes as there are
tubes in the second boiler, and I fix, screw, or couplo into the holos of
the rose end pipes or tubes, which tubes or pipes ends rest in the tubes
of the second steam boiler, so that the steam from the exhaust of
the first engine cylinders is equally distributed through the tubes in the
second boiler, forming a suction for the products of combustion from the
furnace in the first boiler, which forces the same through the second
boiler tubes and up the chimney. The funnel-shaped or rose and is made
to slido, so that it will allow the pipes or tubes fixed in the rose end being
drawn out of the tubes in the second boiler on detaching the two ongines
and boilers. A door is fixed in the tubo or chamber, in order to have
access to the pipes or rose end.

page_text: jacketed to keep in the heat within the tubes. At the front of the fire-
box, over the furnace door, I fix an air tube with a metal plate balanced
by a lever. This metal plate is to allow air to come in on the top side of
the door to be brought in contact with the fire. A chain attached to the
door puts the metal plate in a horizontal position when firing, and falls
down gradually by means of a chain and balance weight attached to the
door. I also fix in the air tube over the door a plate or door working on
two pivots, so that the air is cut off when desired.
The arrangement of carrying the two engines and boilers over a curvo
line of railway is on two bogies, allowing the front end of the leading
engine to rise and fall with case, the bogies being so constructed that
curves form no obstruction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Georgo Rydill in the Great Seal Patent Office on
the 23rd August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
RYDILL, of Grove House, Dewsbury, in the County of York send
greeting.

page_text: 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 bo
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 Georgo Rydill, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by tho
following statement :—
-
This Invention relates to improvements in combined steam engines
and boilers on land and sea for more effectually consuming smoko and
saving fuel.
My Invention of improvements relates to the working of sectional
steam boilers on land and sea, which sectional steam boilers are named
in my Specification of December 28th 1872, No. 3938, and in my
3 Specification of January 28th 1873, No. 329, and I further describo the
working arrangements of sectional boilers, showing how they may bo
worked on railways.
This Invention of improvements is in the working of steam engines
and sectional boilers, which I describo as follows; and in order to make
my improvements clearly understood I will call a locomotive steam
engino and boiler attached to a train of carriages the first steam engine'
and boiler, and my improvements in sectional locomotive engine and
boiler I call the second steam engine and boiler, the chimney being, at
tho front end of the second engine boiler:-The chimney of the first
engine and boiler I dispense with or make up, and a tubo or chamber is
fixed to the boiler at the smoke box end of the first steam engine boiler.
The second sectional steam engine and boiler, with its working parts, is.
is every respect like the first steam engine and boiler, except that no
fire-box is in the second engino boiler, which boiler may contain tho.
same number of tubes as the first steam engine boiler, or it may contain
less tubes of larger diameter, or it may contain more tubes than the first
engine boiler, which tubes may bo brought up to the end of the second
steam engine boiler. Projecting beyond the back end of the second
steam engine boiler is a tubo or chamber which is firmly secured to tho'
boiler of any required length or diameter. Affixed to the front end of
the first steam engine boiler, projecting beyond tho boiler or smoke box,
>>

page_text: is a tube or chamber, being of any required length or diameter, which
extends and fits into the interior, or it may fit on to the exterior of the
tube or chamber of the second engine boiler in the form of a sliding
tube of a telescope, which tube or tubes and chambers are made to fit so
that they form a joint or union to resist the steam and the products of i
combustion coming from the first steam engine and boiler. This joint
to resist the smoke and products of combustion from the first engine
and boiler I make with a spring packing oither in one spring or in
spring segments, so that in running round a curvo the spring will give
way. The exhaust steam from the first steam engine and boiler cylinders
is discharged by the exhaust tube or tubes into a bent pipe or tubo in
the form of an elbow which faces the tubes of the second engine boiler,
so that the steam of those cylinders is discharged into the tubes or
chambers which connect the first and second engines and boilers together
so that the exhaust steam from the first engine cylinders passes along 1
with the products of combustion through the connecting tube or
chamber of the two boilers and through the boiler tubes of the second
steam engine boiler, heating the water and raising steam, so that when
the heated products of combustion along with the exhaust steam from
the first engine cylinders reaches the front end of the second engine 2
boiler, which I call the smoke box end, the products of combustion and
the exhaust steam from the first engine cylinders unites with the steam
of the second engine cylinders in passing up the chimney. The exhaust
stcam from the second engine cylinders creates a strong draught through
all the tubes and up the chimney. In this manner the exhaust steam 2
and products of combustion may be carried through any required
number of sectional boilers.
The two engines and boilers are coupled together, having spring
buffers, so that the engines and boilers give and take, as also the spring
attached to the tubes and chambers, which spring is held back with 3
levers when the engine tubes and chambers are coupled together,
enabling curves to be easily run over. By this arrangement several
engines and boilers may be attached together, or a second boiler may be
fixed upon wheels for raising steam only and coupled to the first engino
and boiler, and the exhaust steam from the first engine cylinders may bo 3
carried in pipes to the front end of the second boiler to creato a draught
for the firo and products of combustion from the first engine boiler.

page_text: I prefer to place at the end of the exhaust pipe or pipes a funnel or
bell-mouth shaped roso end, which roso end or bell-mouth contains as
many holes as there are tubes in the second boiler, and I fix, screw, or
couplo into the holes of the bell-mouth or rose end pipes or tubes, which
tubes or pipes' ends rest in the tubes of the second steam boiler, so that
the steam from the exhaust of the first engine cylinders is equally
distributed through the tubes in the second boiler, forming a suction for
the products of combustion from the furnace in the first boiler, which
forces tlio samo through the second boiler tubes and up the chimney.
The bell-mouth or roso end is made to slide so that it will allow tho
pipes or tubes fixed in tho rose end being drawn out of the tubes in tho
second boiler on detaching the two engines and boilers. A door is
fixed in the tubo or chamber in order to have access to the pipes or
roso end.
The tubes forming chambers from ono boiler to another may bo
jacketed to keep in the heat within tho tubes. At the front of the fire-
box over the furnace door I fix an air tube with a metal plate, balanced
by a lever. This metal plate is to allow air to come in on the top sido
of the door which projects to bo brought in contact with the fire. A
chain attached to the door puts the metal plate in a horizontal position.
when firing, and falls down gradually by means of a chain and balance
weight attached to the door. I also fix in the air tube over the door a
plato or door working on two pivots, so that tho air is cut off when
desired.
•
The arrangement of carrying the two engines and boilers over a curve
line of railway is on two bogics, allowing the front end of the leading
engine to rise and fall with case, the bogies being so constructed that
curves form no obstruction.
Having clearly described my Invention, and the principle of locomo
tives being so well understood, I do not feel it necessary to filo Drawings
after my clear explanation shewing the connection of the two sectional
boilers, which may, bo riveted or mado to slido one on to tho other. But
the arrangement of distributing the steam from the cylinders into tubes
may be adapted to licat the feed water or for other purposes. Believing.
that a projecting door with hot air tube is now I feel it my duty to give
Drawings showing how it may be applied to locomotives and otlier steam
boiler furnaces.

page_text: Third. The connection or attaching one boiler to another either by one
boiler tubo sliding on to another to mako a joint by themselves or by
means of spring packing or coupling, or I-rivet the two boiler tubes and
boilers together and carry the same on bogies on railways.
In witness whereof, I, the said George Rydill, have hereunto set
my hand and seal, this Twenty-third day of August, in the year
of our Lord One thousand eight hundred and seventy-three.
