WILLIAM CHAPMAN, 14, Limerston Street, Chelsea, S.W., Builders Foreman,
do hereby declare the nature of this invention to be as follows:-
For Lancashire, Cornish and all other boilers with flues through them, under
them. By the the side of them, or in any position in connection with the
boiler.
Fire clay division with bafflers placed thereon, fixed in the boiler flue, as
described in Cornish boiler:
Cornish boiler, horizontal fire clay division fixed through the whole length
of the boiler flue, from the bridge at the back of the fire to the back end of
the boiler flue. The division to be on a level with the top side of the firebars.
The division is made in narrow widths, from 6" wide and upwards, and, about,
24" thick, fixed across the boiler flue, the edges groved and tongued to fit closely
together. For boilers with cross tubes in the flues, special fire clay slabs are
made to fit round the cross tubes, making the boiler flue tight and compact as
a clear flue without cross tubes.
The division is carried by fire clay bearers, about 4" x 2" fixed on each side
of the boiler flue, supported by fire clay qudrants, 4" x 22", made to fit the
boiler flue.
The bearers and supports can also be made in angle and bar iron.
Bafflers made in fire clay to stand in the division.
These bafflers are made with bottom plate, about, 10" x 11" with plates to
fit the side and crown of the boiler flue, about 6" x 14". Between these plates
louvers are fixed at an angle of, about, forty-five degrees, and, about, 11" apart.
These bafflers are made right and left handed, and placed alternately, from
side to side, on the division, extending three fourths of the distance across the
boiler flue, and in numbers suitable to the size of the boilers.
The bafflers are placed in position on the division by the aid of a long arm,
made in round, or flat bar iron, with forked ends, and turned down points to
catch in the slotted holes in the bottom plate of the bafflers.
The fire clay division through the boiler flue, with the bafflers thereon, arrest,
retain, and utilise the heat, in place of the said heat passing away to the
chimney.
The bafflers standing on the division, some 15" apart and extending three
fourths of the distance across the boiler flue, from either side, covering the line

louvers of the bafflers, and be consumed by the heat created in the fire clay
division and bafflers.
The bafflers to be made in all sizes and shapes to fit any flue whatever.
The division and bafflers can be used together or separately in flues of kilns,
coppers, ovens, and every kind and description of flues connected with stationary,
travelling, marine and all other steam boilers.

WILLIAM CHAPMAN, 14, Limerston Street, Chelsea, Builder's Foreman, 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:-
Improved method for consuming smoke from stationery boiler furnaces &
from all & every kind and description of furnaces whatever.
For Lancashire, Cornish & all other boilers.
Fire clay divisions, A. This division is made in fire clay and fixed hori-
zontally through the centre of the boiler flue from the bridge B at the back of
the fire to the end of the boiler flue & on a level with the top side of the fire
bars C.
This division is made in pieces varying from 1 foot to two feet wide, by
about two and a half inches thick, the edges to be groved & tongued to fit
closely together. This division rests upon angle iron bearers fixed on each side
of the flue & supported by flat iron bars bent to fit boiler flue, and turned at
the ends to fit the angle iron.
The above bearers can also be made in fire clay.
Fire clay bafflers D shown separately in Figs. 4 and 5.
These bafflers are made in fire clay with a wide bottom plate E, Figs. 4 & 5,
with circular side & top plate, F about six inches wide, to fit the boiler flue.
Between these plates louvres G are filled in about two inches apart, and at
an angle of 45%. These bafflers are made right & left handed and placed alter-
nately on the division on each side of the boiler flue, extending of the distance
across the flues and in such numbers to suit the size of the boiler. These hafflers
are placed in position by the aid of a long arm with forked ends & turned down
points to catch in the slotted holes in the bottom plate of the bafflers.
This fire clay division through the centre of the boiler flue, with the fire clav
bafflers placed thereon will arrest, retain & utilise the heat instead of the said
heat passing away to the chimney.
The bafflers standing on the division, about 15 inches apart, and extending
three fourths of the distance across the flue from either side thus covering the
line of each other in the centre of the flue, cause the smoke to pass through &
between the louvres, and be consumed before reaching the end of the boiler flue,
through and by the heat created by the fire clay bafflers.
The fire clay division and bafflers, can be used in every description & kind
of flue whatever, & can be made in all sizes & shapes & made together or
separately in furnaces and flues of kilns, coppers & ovens of every description.

page_text: The above device can be applied to all furnaces & flues already constructed.
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what
I claim is:
