Boiler and other Furnaces.
JAMES RIXSON Bleacher 35 Chelsea Terrace Elton Bury Lancashire do hereby
declare the nature of my invention to be as follows:-
By building a bridge about 10 inches from the end of fire bars. Then fixing an
iron cross bar across the middle of flue and build another bridge about one inch from
the other bridge & one inch higher on both bridges I fix an iron plate the back
bridge being 1 inch lower than front bridge it allows one inch for the air to get
from between the 2 bridges two bridges being red hot and the iron plate being red
hot the air going between two red hot bridges & against a red hot plate the air
almost red hot too, this air being full of oxygen gas when it gets from under the
plates ignites with the flame from the furnace and consumes the smoke.

COMPLETE SPECIFICATION.
Improvements in Smoke Consuming Arrangements for Steam
Boiler and other Furnaces.
I JAMES RIXSON Bleacher 35 Chelsea Terrace Elton, Bury, Lancashire, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
I construct (of brick & iron) the bridges of boilers in such a manner that fresh
air is caused to pass through & between the said bridges & during such passage is
caused to become hot, & is then caused to mix with the smoke from the fire &
consume it. I do this in the manner following, I build the bridges in two parts,
one part being in front of the other & about one inch from each other as shown
at (B B) in the drawings. In the front part of this bridge, I construct
passages p, p, p the letters all refer to the drawings, below the level of the fire
bars (b) & the fire bars bearer (D) such passage being for the inlet of fresh
air, (A) as shown in the drawings, the air passing through, p, p, p gets in the space
between the fore & back parts of the bridges & turn upwards covering this space
at the top of the bridges but still allowing a passage for the air, is a plate (P) of
iron or other suitable material against which the air impinges or comes in contact
with & then passes along under this plate & emerges above the bridge & mixes
with the smoke at (As) as shown.
Now the bridges being very hot & the plate (P) being red hot from the heat of
the fire the air in its passage becomes so heated that when mixed with the smoke
at (As) the smoke is consumed.
The explanation on the drawings & not above referred to, are as follows,
W, W is the water in the boiler.
S is the boiler shell.
FF is the boiler flue

page_text: Having now particularly described & ascertained the nature of my said inven-
tion & the way the same is to be performed & constructed I declare that what
I claim is
(1) That by thus heating the air in the manner described the air gets more
nearly to the heat of the fire & thus becomes more able to consume the smoke than
by previous methods.
I claim the method of passing air through the bridge as described.
(3) I claim the use of the cover plate (P) on the top of bridge for insuring the
air becoming hot enough to consume the smoke.
