"The
tested
gain
by
the
use
of
this
grate
is
an
increase
of
15
degrees
of
temperature,
with
a
saving
of
one-third
in
fuel.
I
believe
that
there
are
several
millions
of
grates
on
the
wrong
principle,
hurrying
the
heat
up
the
chimney
instead
of
into
the
room,
and
thus
causing
an
in-draught
of
cold
air.
This
is
especially
the
case
with
strong
drawing
registers.
No
part
of
a
grate
should
be
of
iron,
except
the
thin
front
bars;
for
iron
is
a
conductor
away
of
heat,
but
fire-bricks
are
not
so."
The
principle
of
the
grate
is
thus
explained
by
a
writer
in
'The
Field',
who
says:
"If
any
of
your
readers
are
troubled
with
smoky
fires
and
cold
rooms,
allow
me
to
recommend
them
to
follow
Mr.
Mechi's
plan,
as
I
have
done.
Remove
the
front
and
bottom
bars
from
any
ordinary
grate;
then
lay
on
the
hearth,
under
where
the
bars
were,
a
large
fire
tile,
three
inches
thick,
cut
to
fit
properly,
and
projecting
about
an
inch
further
out
than
the
old
upright
bars.
Then
get
made
by
the
blacksmith
a
straight
hurdle,
twelve
inches
deep,
having
ten
bars,
to
fit
into
the
slots
which
held
the
old
bars,
and
allow
it
to
take
its
bearing
upon
the
projecting
fire-brick.
The
bars
should
be
round,
of
five-eighth
inch
rod,
excepting
the
top
and
bottom,
which
are
better
flat,
about
1-1/4
in.
broad.
My
dining-room
grate
was
thus
altered
at
a
total
cost
of
eighteen
shillings
two
years
ago,
the
result
being
that
a
smoky
chimney
is
cured,
and
that
the
room
is
always
at
a
really
comfortable
temperature,
with
a
smaller
consumption
of
coal
than
before.
The
whole
of
the
radiation
is
into
the
room,
with
perfect
slow
combustion."
