IMPROVE- MENTS IN BOILERS, AND IN APPARATUS FOR EFFECTING THE CONSUMPTION OP. SMOKE IN THE FURNACES OF BOILERS."
Year: 1868

page_text: LETTERS PATENT to Thomas Beeley, of Hyde Junction Iron Works, in
the County of Chester, Engineer, for the Invention of "IMPROVE-
MENTS IN BOILERS, AND IN APPARATUS FOR EFFECTING THE CONSUMPTION OP.
SMOKE IN THE FURNACES OF BOILERS."
PROVISIONAL SPECIFICATION left by the said Thomas Beeley at the
Office of the Commissioners of Patents, with his Petition, on the
30th April 1868.
I, THOMAS BEELEY, of Hyde Junction Iron Works, in the County of
Chester, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN BOLLERS, AND IN APPARATUS FOR EFFECTING THE CON-
SUMPTION OF SMOKE IN THE FURNACES OF BOILERS," to be as follows:-
My improvements consist, in the first place, in attaching the cross
tubes in the flues of boilers to the flues by welding them in, these

page_text: tubes having been hitherto attached to the flues by rivetted joints,
which possess the disadvantage of being liable to leak.
The most convenient mode of putting this part of my Invention into
practice is as follows:-The parts to be attached being brought to the
required heat the flue is placed upon an anvil made of such a form that
it extends about half way round the tube, and fits up into the corner
formed by the tube and the flue. The parts are then welded together,
the flue being turned round as may be necessary.
In the second place my improvements refer to an improved apparatus
for effecting the consumption of the smoke in the furnaces of boilers.
To effect this I employ a partition or midfeather extending longi-
tudinally through a portion of the furnace, so as to divide the back into
two separate chambers. A communication may be made between these
chambers by means of a number of holes in the partition, and these
holes communicate with the air by means of other holes leading from
them down to the space below, the grate bars. At the back of the
partition is a swing door, by means of which only one of the chambers
can be closed at a time, and it is arranged so that it is commanded to a
certain extent by the movements of the fire door. This is accomplished
as follows:-The fire door is made in. two halves corresponding to the
two chambers. In connection to each of these doors is a quadrant,
upon which is a catch or shoulder in such a position that when the
door is opened it must pull the quadrant with it, but the door:
may be
shut again without moving the quadrant. The quadrants are connected
with the swing door at the back of the furnace by means of chains and
rods passing round a pulley, and they are so arranged that when
either fire-door is opened the corresponding chamber is closed by the
swing door.
•
The action of the apparatus is as follows:-The man opens one of the
doors, thus drawing out the quadrant and closing the corresponding
chamber by the swing door; he then throws in the coal and closes the
door without moving the quadrant. A large quantity of smoke is
necessarily produced in this chamber, but the chamber being closed
this smoke must either return and pass round in front of the partition or
pass through the holes, in doing which it gets well mixed with the air 8
rising up the holes leading from the ash space; it has then to pass over
the incandescent fuel in the other chamber, where it is effectually

page_text: consumed. When it is necessary that both chambers be open at the
same time both quadrants should be drawn half way out. Levers may
be used instead of the quadrants. Instead of being of fire-brick the
partition or midfeather may be a water space.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Beeley in the Great Scal Patent Office on
the 30th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BEELEY, of Hyde Junction Iron Works, in the County of Chester,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Beeley, Her special licence that
I, the said Thomas Beeley, my executors, administrators, and assigns, or
such others as I, the said Thomas Beeley, 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 BOILERS, AND IN
APPARATUS FOR EFFECTING THE CONSUMPTION OF SMOKE IN THE FURNACES OF
BOILERS, upon the condition (amongst others) that I, the said Thomas
Beeley, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly 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.

page_text: be performed, to be particularly described and ascertained in and by the
following statement :-
My improvements consist, in the first place, in attaching the cross
tubes in the flues of boilers to the flues by welding them in, these
tubes having been hitherto attached to the flues by riveted joints which
posses the disadvantage of being liable to leak.
The most convenient mode of putting this part of my Invention into
practice is as follows:-The parts to be attached being brought to the
required heat the flue is placed upon an anvil made of such a form that
it extends about half way round the tube and fits up into the corner
formed by the tube and the flue. The parts are then welded together,
the flue being turned round as may be necessary.
In the second place my improvements refer to an improved apparatus
for effecting the consumption of the smoke in the furnaces of boilers.
To effect this I employ a partition or midfeather extending longi-
tudinally through a portion of the furnace so as to divide the back into
two separate chambers. A communication is made between these
chambers by means of a number of holes in the partition, and these
holes communicate with the air by means of other holes leading from
them down to the space below the grate bars. At the back of the
partition is a swing door, by means of which only one of the chambers
can be closed at a time, and it is arranged so that it is commanded to a
certain extent by the movements of the fire-door. This is accomplished
as follows:-The fire-door is made in two halves corresponding to the
two chambers. In connection with each of these doors is a quadrant
upon which is a catch or shoulder in such a position that when the door
is opened it must pull the quadrant with it, but the door may be shut
again without moving the quadrant. The quadrants are connected with
the swing door at the back of the furnace by means of chains and rods
passing round a pulley, and they are so arranged that when either fire-
door is opened, the corresponding chamber is closed by the swing
door.
The action of the apparatus is as follows:-The man opens one of the
doors, thus drawing out the quadrant and closing the corresponding
chamber by the swing door. He then throws in the coal and closes the
door without moving the quadrant. A large quantity of smoke is

page_text: necessarily produced in this chamber, but the chamber being closed this
smoke must either return and pass round in front of the partition or
pass through the holes, in doing which it gets well mixed with the
air rising up the holes leading from the ash space. It has then to
pass over the incandescent fuel in the other chamber, where it is
effectually consumed. When it is necessary that both chambers should
be open at the same time both quadrants should be drawn half way
out. Levers may be used instead of the quadrants. Instead of being
fire-brick the partition or midfeather may be a water space.
In the annexed Drawings Fig. 1 shews an end view of a flue
provided with my improved apparatus for burning smoke; Fig. 2 is a
longitudinal section; Fig. 3 is a transverse section shewing the swing
door at the back; Fig. 4 is a transverse section through the fire-brick
partition, and Fig. 5 is a horizontal section. The same letters refer to
all these Figures.
A, A, is the front door, which. is made in two halves as shewn;
B, B, is the fire-brick partition perforated by the holes C, C, which
communicate with other holes D, D, leading from the ash space. E is
the swing door. The quadrants are shewn at F, F; these quadrants
are connected to the pulley G on the axis of the swing door by means
of the chains & rods H, H. The proportions of the quadrants and
the pulley G must be so arranged that the movement of the quadrants
is sufficient to impart the necessary amount of motion to the swing
door.
Figs. 6, 7, 8, 9, & 10 illustrate the method I adopt to weld the cross
tubes into the flues; Figs. 6 and 7 being two views of an anvil con-
structed for this purpose. To use this anvil it is mounted on a stand
such as that shewn at A, Figs. 8, 9, and 10, the upper portion of which
is capable of being turned in different directions in a horizontal plane.
Figs. 8, 9, & 10 shew a tube being welded into a portion of a flue,
but the anvil shewn in these Figures is different in its construction
from that just described, being arranged so that one end of the tube
can be welded at once without the necessity of turning the flue round.
This anvil block is made in two portions B and C, one of these B is a
fixture, the other C being fixed on to the axis D so that by means of the
lever E it may be moved away from the side B and the anvil be thus

page_text: opened to admit the tube, the weight F keeping it up to its place while
the tube is being welded.
In witness whereof, I, the said Thomas Beeley, have hereunto set
my hand and seal, this Twenty-ninth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight.
