Abating Smoke.
HENRY JUSTINIAN NEWCOME Shenley Hertfordshire, Clergyman, 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 :-
This invention is mainly designed for use in connection with open hearth fire
grates, but also with stoves of any description burning either solid fuel, oil or gas-
its object being to heat the air of a room by means of utilizing a great part of the heat
which would otherwise escape with the smoke up the chimney.
For this purpose I use a flat box or chamber of iron or other metal, exposing as
much surface as practicable to the air of the room, and through this chamber, I compel
the hot smoke proceeding from the grate or stove to pass before making its exit up the
chimney or flue pipe. This chamber may be divided internally by diaphragms into
several compartiments, the whole forming a continuous flue of one or several con-
volutions, through which the heated smoke passes on its way to the chimney. The
surfaces of this chamber thus become heated, and the heat is communicated to the
air of the room.
In order that my invention and the mode of carrying it out may be fully understood,
I will proceed to describe the same with the aid of the accompanying drawings
fig. 1. 2. 3. 4. 5. 6. 7. and 3 whereof Fig. 1 is a front elevation; Fig. 2 a plan;
Fig. 3 a vertical section through the line A B on Fig. 2; Fig. 4 a vertical section
through the line G. H. on Fig. 2. Fig. 5 a vertical section through the line CD
on Fig. 2. Fig. 6. a vertical section through the line E F on Fig. 2; and Fig. 7 a
sectional plan through the line I K. on Fig. 5. The Figures together with Fig. 3ª to
be hereafter described are illustrative of one mode in which my invention may be
carried out. The letters on each Fig. indicate corresponding parts.
A horizontal plate 'a' is fitted over the grate, its object being to prevent the smoke
going directly up the chimney; the front part of this plate '6' is bent vertically
downwards and continued to the bottom of the grate or thereabouts, and forms a
"blower." It is supported by two hooks "gg" fitting over the topmost bar of the
го

grate. In the centre of the blower I prefer to make a rectangular aperture closed by
one or two doors "c"c" which may be opened by means of the handles s. "s." when
it is required to reduce the draught or replenish the fuel in the grato. These doors are
shewn open by the dotted lines on Fig. 3 and 3. In the horizonal plate a" is an
aperture "d" through which the smoke passes into or through the smoke chamber.
This chamber or portable chimney "e" is a rectangular box formed horizontally in
the shape of the letter T and is supported in front by two standards or tressles """"
and at the back rests upon the plate "a." This chamber or chimney is divided
longitudinally by a vertical diaphragm " 9," apertures """h" being left at each end
for the passage of the smoke from one half of the chamber to the other, and it is
divided in a transverse direction by another diaphragm " "preferably inclined at
an angle as shewn in figs. 5 and 6 the object of the inclined direction being to obtain
a greater width for the aperture "" in the bottom of the chamber corresponding to
and immediately over the aperture "d" in the plate "a." In the top of the smoke
chamber on the other side of the diaphragm "" is another aperture ";" through
which the smoke finally escapes up the chimney.-The course of the smoke after
leaving the grate is indicated in Figs. 2 3 and 4 by the arrows numbered 123456
respectively and follows the arrows in the order of these numbers. Passing through
the apertures "d" and "" into the smoke chamber as shewn by the arrow 1 in fig. 3
the smoke then traverses the chamber in both directions on each side of the diaphragms
successively as shewn by the arrows 2 3 4 5 on Fig. 2 finally emerging through the
aperture "" into the chimney as indicated by the arrow 6 in figs. 3 and 4. In a
very short time the outer surface of the smoke chamber becomes considerably heated
and the heat is communicated to the air of the room.
In Figs. 1 & 2 part of the side and top respectively of the chamber "e" are
supposed to be cut away in order to shew its interior. The ends of the smoke chamber
are closed by movable caps "kk" and "" by the removal of which a brush may be
inserted to clean out the soot deposited by the smoke in its passage through the
chamber.

To meet those occasions on which it may be desirable without removing the
apparatus, to allow the smoke to escape directly up the chimney, for instance on
first lighting the fire, there is another aperture m in the top of the chamber
immediately above the aperture "" in the bottom. This aperture is ordinarily
closed by a sliding damper "n "actuated by a rod "o" and handle "p." Fig. 3ª
is a vertical section on the same line as fig. 3 but shewing the damper pulled
forward and the hole " m "uncovered. The smoke can then escape directly from the
grate up the chimney as indicated by the arrow on Fig. 3ª.

Having thus particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim
1st. The construction and use of a Portable Flue or Chamber substantially as here
described, through which the heated smoke proceeding from either an open hearth
fire grate or a close stove is compelled to pass before escaping up the chimney.
2nd. The power of obtaining nearly instantaneous warmth from the smallest quantity
of fuel and so warming any apartment in a shorter space of time than can be done by
either stoves or open fire grates.
3rd. The abatement of smoke by retaining the soot in the smoke chamber.
