line with the space enclosed by the plates below and in
communication therewith, substantially as specified. (3.) In
boiler and other furnaces, a double fire-bridge at the back
of the furnace arranged with a vertical space between, a space extending beneath the grate, double plates
arranged within such space with a vertical space between
them in a direct vertical line with the space between
the double bridge and in communication therewith, the outer
one of such plates being formed with air-apertures therein,
in combination with means whereby such apertures will be
kept normally covered and will be opened upon the furnace-
door being opened and then gradually covered again after
the furnace-door has been closed, substantially as specified.

(4.) In boiler and other furnaces, a space extending beneath
the furnace, double plates beyond the back end of the fur-
nace arranged with a vertical space between in communica-
tion with the back of the furnace, air-openings in the outer
