REMOVAL OF DUST ASHES AND CINDERS THEREFROM AND IN THE ABATEMENT

"
PROVISIONAL SPECIFICATION left by the said Richard Wright at the
Office of the Commissioners of Patents on the 13th March 1882.
RICHARD WRIGHT of Richmond in the County of York. "IMPROVEMENTS
IN FIRE GRATES FOR FACILITATING THE REMOVAL OF DUST ASHES AND CINDERS
THEREFROM AND IN THE ABATEMENT OF SMOKE ARISING FROM FUEL BURNT
THEREIN
"
This Invention has for its object improvements in fire grates for facilitating the
removal of dust ashes and cinders therefrom and in the abatement of smoke arising
from fuel burnt therein.
For the abatement of the smoke arising from coals burnt in the fire grate,
powdered lime dry as from the kiln is used. After the fire in the grate has been
lighted and is burnt up a small quantity of lime is sprinkled on the top of the
coals and as often as more coals are put on the fire the lime is sprinkled on the
top. The lime thus sprinkled has the effect of reducing the quantity of smoke
to a minimum and prevents any sulphureous gases from escaping into the
room.
I sometimes employ a composition of coal, lime and clay as fuel. The materials
are ground and mixed together, made into bricks or lumps and dried this fuel is
more durable than coal cheaper and produces less smoke.
In the construction of fire grates to render more easy speedy and convenient the
removal of the refuse of the fuel used in such grates, I forin the grate stand about
13 inches from the ground having a depth of about 7 inches or more as desired
and with from 4 to 6 bars in the front straight or only a little projecting if 80
desired with a somewhat narrow top but showing a rather deep frontage of fire.
Instead of a fixed bottom to the grate is placed a grate with small bars filling up
the entire bottom and so constructed as to slide in and out in a similar manner to
the drawer bottom of a bird cage having a knob or handle in front for that
purpose. Underneath this grate or bottom is placed a box or pan fitting to the
sides of the grate so that when the grate or bottom is pulled out the dust ashes and
cinders may fall into it and thus be easily carried away.

This Invention has for its object improvements in fire grates for facilitating the
removal of dust ashes and cinders therefrom and in the abatement of smoke arising
from fuel burnt therein.
+
For the abatement of the smoke arising from coals burnt in the fire grate
powdered lime dry as from the kiln is used. After the fire in the grate has been
lighted and is burnt up a small quantity of line is sprinkled on the top of the
coals and as often as more coals are put on the fire the lime is sprinkled on
the top.
The lime thus sprinkled has the effect of reducing the quantity of
smoke to a minimum and prevents any sulphureous gases from escaping into the
room.
I sometimes employ a composition of coal lime and clay as fuel-The materials
are ground and mixed together, made into bricks or lumps and dried.
This fuel is more durable than coal cheaper and produces less smoke.
In the construction of fire grates to render more easy speedy and convenient the
removal of the refuse of the fuel used in such grates I form the grate to stand about
13 inches-from the ground having a depth of about 7 inches or more as desired
and with from 4 to 6 bars in the front straight or only a little projecting if so
desired with a somewhat narrow top but shewing a rather deep frontage of fire.
Instead of a fixed bottom to the grate is placed a grate with small bars. filling up
the entire bottom and so constructed as to slide in and out in a similar manner. to
the drawer bottom of a bird cage having a nob or handle in front for that purpose
-Underneath this grate or bottom is placed a box or pan fitting to the sides of
the grate so that when the grate or bottom is pulled out the dust ashes and cinders
may fall into it and thus be easily carried away.
.
The annexed drawing shows a fire grate constructed according to my invention.
-a is the bottom grating filling up the bottom of the fire basket and arranged to
pull out like a drawer-b is a box or pan to receive the ashes; it also runs in
guides and can be withdrawn like a drawer-At c the lime sprinkled upon the top
of the fuel is represented.
What I claim is, my improvements in fire grates and in the abatement of smoke
arising from fuel burnt therein substantially as described.
In witness whereof I the said Richard Wright have hereunto set my
hand and seal this 29th day of August in the year of our Lord One
thousand eight hundred and eighty two.
RICHARD WRIGHT. (L.S.)
