page_text: LETTERS PATENT to Joseph Rhodes, Enoch Rhodes, Cotton Warp
Sizers and Dressers, and William Frankland, Manager, all of
Bradford, in the County of York, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING FUEL FOR
STHA ARVORATORE
AND Y ADAMS
دو
PROVISIONAL SPECIFICATION left by the said Joseph Rhodes, Enoch
Rhodes, and William Frankland at the Office of the Commissioners
of Patents, with their Petition, on the 21st April 1873.
We, JOSEPH RHODES, ENOCH RHODES, Cotton Warp Sizers and
Dressers, and WILLIAM FRANKLAND, Manager, all of Bradford, in the
County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING
FUEL FOR STEAM GENERATORS AND FIRE-GRATES," to be as follows, that is
to say:-
Our Invention relates to employing the draught or current of air
coming through the firc-door which we cause to pass downwards,

page_text: forcing the smoke and gases to pass through the fire, thereby con-
suming the smoke and economizing fuel. For this purpose we employ
a fire-brick bridge fitted in the fire-tube or flue of the boiler in the
usual way, but instead of being open at the top as heretofore to allow
of the escape of smoke and gases, it is closed and an opening is mado
in the bottom part of the fire-brick bridge underneath the fire-bars; the
present opening left in the front part of the ash-pit through which a
current of air passes is also closed by means of a door, allowing by these
means the draught or current of air to come through the fire-door and
to pass downwards through the fire; forcing the smoke and gases to
pass through the said fire, thereby consuming the smoke and leaving
only hot air and gases to pass through the bottom door or opening
in the fire-brick bridge into the boiler flue and side flues to the
chimney.
In the fire-brick bridge are fixed doors one in the top and one in the
bottom; they are actuated by hand gear and are for the purpose of
admitting the draught or current of air over the fire when the fuel is
free from smoke; in that case the bottom door is shut and the top
door open.
We can do away with the bottom door and leave an open
space in the bottom of the bridge, if found desirable, by using the front
door fitted on the ash-pit front.
A small bridge is also used placed in the fire flue and at a short
distance from the fire-brick bridge; this small bridge is for the
purpose of preventing ashes and cinders entering the flue of the
boiler.
The stoking door is made with a slide and openings to regulate the
admission of atmospheric air.
We can also employ the draught or current of air to act upward
or downward in the case of more than one fire being in proximity.
For fire-grates we employ the same system of forcing the draught
downwards; for this purpose our grates are made with openings under
the fire-grates through which the gases, heated air, and smoke (if any)
pass, and through openings made behind the fire-places forming a back
flue into the chimney.
The top of the fire-places is fitted with iron plates having holes cast
therein to admit of kettles, saucepans, or boilers, being placed thercon ;
these holes have covers fitted to them.

TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOSEPH
RHODES, ENOCH RHODES, Cotton Warp Sizers and Dressers, and
WILLIAM FRANKLAND, Manager, all of Bradford, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Joseph Rhodes, Enoch Rhodes, and William
Frankland, Her special licence that we, the said Joseph Rhodes, Enoch
Rhodes, and William Frankland, our executors, administrators, and
assigns, or such others as we, the said Joseph Rhodes, Enoch Rhodes,
and William Frankland, 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 "IMPROVEMENTS IN APPARATUS FOR CONSUMING
SMOKE AND ECONOMIZING FUEL FOR STEAM GENERATORS AND FIRE-GRATES,"
upon the condition (amongst others) that we, the said Joseph Rhodes,
Enoch Rhodes, and William Frankland, 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,

page_text: 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 Joseph Rhodes, Enoch Rhodes,
and William Frankland, do hereby declare the nature of the 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 employing and causing the draft or
current of air coming through the fire-door to pass downwards and
force the smoke and gases to pass through the fire, thereby consuming
the smoke and economizing fuel. For this purpose we employ a
fire-brick bridge fitted in the fire-tube or flue of the boiler in the
usual way, but instead of being open at the top as heretofore to allow
of the escape of smoke and gases, it is closed and an opening is made
in the bottom part of the fire-brick bridge underneath the fire-bars; the
present opening left in the front part of the ash-pit through which a
current of air passes is also closed by means of a door, allowing by these
means the draft or current of air to come through the fire-door and
to pass downwards through the fire, and forcing the smoke and gases to
pass through the said fire, thereby consuming the smoke and leaving
only hot air and gases to pass through the bottom door or opening
in the fire-brick bridge into the boiler flues and side flues to the
chimney.
In the fire-brick bridge are fixed doors one in the top and one in the
bottom; they are operated by hand gear and are for the purpose of
admitting the draft or current of air over the fire when the fuel is free
from smoke; in this case the bottom door is shut and the top door
open. We can do away with the bottom door and leave an open space
in the bottom of the bridge if found desirable by using the front door
fitted on the ash-pit front.
A small bridge is also used which is placed in the fire flue and at a
short distance from the fire-brick bridge; this small bridge is for the
purpose of preventing ashes and cinders entering the flue of the
boiler.

page_text: The stoking door is made with a slide and openings to regulate the
admission of atmospheric air.
We can also cause the draft or current of air to act upward or
downward in the case of more than one fire being in proximity.
For fire-grates we employ the same system of forcing the draft
downwards. For this purpose our improved grates are made with
openings under the fire-grates, through which the gases, heated air,
and smoke (if any) pass, and through openings made behind the fire-
places forming a back flue into the chimney.
The top of the fire-places is fitted with iron plates having holes cast
therein to admit of kettles, saucepans, or boilers being placed thereon;
these holes have covers fitted to them.
On the top of the fire-bars are fitted frames fixed to the sides of the
oven and boiler; in these frames are fitted circular doors working on
hinges; these doors are for the purpose of putting in the coals.
Dampers are fitted in a back flue leading to the chimney for regulating
the admission of the draft.
But in order to enable our improvements to be better understood
we will proceed to describe the same by reference to the accompanying
Drawing in which Figure 1 represents a front view of boiler flucs,
shewing outside view of door frame with doors, and a sectional front
view of longitudinal hollow fire-bars and back water bridge; Figure 2,
sectional elevation; and Figure 3, plan of the same.
.
Figure 4 represents a front view of the boiler flues shewing an
outside view of door frame and sectional front view of horizontal hollow
fire-bars; Figure 5, plan of the same. Similar letters of reference are
used in all the Figures to represent similar parts.
A, fire-brick bridge closed at the top and open at the bottom part B
through which the gases and hot air pass; the openings left in the front
part of the ash-pit C are closed by means of the doors D, thus allowing
the draft or current of air to pass through the openings E of the
fire-door F fitted on the door frame G, causing the current of air to
come through the openings E of the fire-door and to pass downwards
through the fire, and forcing the smoke and gases to pass through the
said fire, thereby consuming the smoke and leaving only hot air and

page_text: gases to pass through the opening B into the boiler flues to the
chimney. We may use doors fitted in the fire-bridge A, one at the
top and one at the bottom part B; these doors are operated by hand
gear and are for the purpose of admitting the draft or current of air
over the fire when the fuel is free from smoke; H, small fire-brick
bridge for preventing ashes and cinders entering the flue of the boiler;
K, front water bridge fixed in the front part of the fire-place supported
on brackets I; L, back water bridge supported on brackets J fitted to
the boiler flue longitudinal hollow fire-bars M. are fitted to the
bridges K and L in which the water coming through the feed pipe N
circulates and enters the boiler in a heated state through the pipe O,
the feed pipe N if necessary may be fitted up with a branch pipe and
tap; this branch is fitted to the front water cistern K or water tube R¹
and connected to the boiler, a branch pipe being fitted to the feed pipe,
allowing the means of shutting off the feed water when necessary, and
giving a constant circulation to the water in the boiler and fire-bars
independently of the feed water; P, brass or metal plugs screwed into
the front water bridge K for the purpose of cleaning out the hollow
fire-bars or tubes M; the water bridge K forms the dead plate in the
fire-place, the longitudinal hollow fire-bars are inclined towards the
front of the boiler; Q, horizontal hollow fire-bars fitted in wrought-iron
water tubes R and R'; in these tubes R and R¹³ are fitted metal plugs
U; screwed in these plugs are placed alternately the water tubes; R
and R¹ are supported on brackets S rivetted to the boiler flue; the feed
water enters through the feed pipe T passes through the water tu be R¹
and through the hollow horizontal fire-bars or tubes Q into the water
tube R, and enters in a heated state the boiler through the pipes V
and W; Y, fire-clay lining to prevent coals or cinders falling between
the water tubos R and R' and the sides of the flue.
Our improved fire-grates are constructed on the same system of
forcing the draft downwards as herein-before described, and we use a
plate placed in the front part of the ash place to force the draft to pass

page_text: ment of the several parts, substantially as herein-before described and
represented in the accompanying Drawing.
In witness whereof, we, the said Joseph Rhodes, Enoch Rhodes,
and William Frankland, have hereunto set our hands and seals,
this Twentieth day of October, in the year of our Lord One
thousand eight hundred and seventy-three.
