PROVISIONAL SPECIFICATION.
Improvements in Fire or other Bricks for Boiler Seating and Flues,
and in Seatings and Flues Constructed therewith.
I, WILLIAM POULTON, Manufacturer, of The Adamantine Brick Works,
Reading, in the County of Berks. dó hereby declare the nature of this invention to
be as follows:-
My invention relates to the fire or other bricks used for boiler seatings and
flues. In such boiler seatings and flues as at present constructed certain great
disadvantages are now experienced which it is my object to remedy. In the said
boiler seatings and flues the metal of the boiler rests upon broad surfaces of
brickwork and considerable surfaces of brickwork forming the upper parts and the
ends of the flues rest upon the metal of the boiler and it is well known that at these
considerable surfaces of contact the boiler plates are exceedingly liable to serious
oxidation and deterioration due to the accumulation of moisture in the brickwork,
and defects are often hidden by the broad surface of the brickwork.
To avoid this serious danger I have produced the present invention, and in
carrying my invention into effect I construct terminal bricks with circular or
curved. edges where the said bricks are intended to come into contact with the
boiler plates. In constructing boiler seatings and flues I arrange to rest the boiler
on or against the said circular or curved edges of my bricks and I rest the circular
or curved edges of my flue cover blocks or terminal blocks so that both in the
seating and at the points of contact of the brickwork with the boiler I reduce what
is at present a broad surface of contact to a mere line of contact.
By my invention I greatly increase the life of a boiler and cover so little of the
boiler surface with brickwork in contact with the said surface that I am easily able
to keep the whole metallic surface of the boiler in an excellent state of preservation,
and at the same time I can easily inspect the whole surface without substantial
disturbance of the brickwork.

Improvements in Fire or other Bricks for Boiler Seating and Flues,
and in Seatings and Flues Constructed therewith.
I, WILLIAM POULTON, Manufacturer, of The Adamantine Brick Works,
Reading, in the County of Berks. 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 :-
My invention relates to the fire or other bricks used for boiler seatings and flues.
In such boiler seatings and flues as at present constructed certain great disadvantages
are now experienced which it is my object to remedy. In the said boiler seatings
and flues the metal of the boiler rests upon broad surfaces of brickwork and
considerable surfaces of brickwork forming the upper parts and ends of the flues
rest upon the metal of the boiler and it is well known that at these considerable
surfaces of contact the boiler plates are exceedingly liable to serious oxidation and
deterioration due to the accumulation of moisture in the brickwork, and defects are
often hidden by the broad surface of the brickwork.
To avoid this serious danger I have produced the present invention.

page_text: Referring to the accompanying sheet of drawings
:-
Figure is an elevation of a Lancashire boiler showing in section a brick setting
constructed in accordance with my invention.
Figure 2 is a transverse section corresponding to Figure 1.
Figure 3 shows in end and side elevations a brick constructed in accordance with
my invention.
In carrying my invention into effect I construct terminal bricks as A B C with
circular or curved edges where the said bricks are intended to come into contact
with the boiler plates of the boiler E. In constructing boiler seatings and flues I
arrange to rest the boiler on or against the said circular or curved edges of my
bricks as at B and I rest the circular or curved edges of my flue cover blocks A or
terminal blocks C so that both in the seating and at the points of contact of the
brickwork with the boiler I reduce what is at present a broad surface of contact to
a mere line of contact.
This is clearly shown at Figures 1 and 2, where A A are the flue cover. blocks
with a curved edge in contact with the boiler surface. B B are the seating bricks
also with curved edges and C illustrates the terminal blocks.
By my invention I greatly increase the life of a boiler and cover so little of the
boiler surface with brickwork in contact with the said surface that I am easily able
to keep the whole metallic surface of the boiler in an excellent state of preservation,
and at the same time I can easily inspect the whole surface without substantial
disturbance of the brickwork.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. An improved fire brick for boiler seatings, flues and terminals having a semi-
circular or curved edge which edge is placed in contact with the boiler plates where
necessary and so reduces the surface of contact to a minimum substantially as and
for the purposes hereinbefore described reference being had to the accompanying
drawings.
2. The construction of boiler flues and seatings in such manner that the positions
of contact of the boiler with the brickwork occur at curved brick surfaces and so
form lines of contact only instead of broad surfaces of contact substantially as and
for the purposes hereinbefore, described.
