I, STEPHEN FRANCIS SMITH, of Brunswick House, 309 Holloway Road,
London, N, County of Middlesex, Physician, do hereby declare the nature of my
invention for AN APPARATUS FOR CARRYING OFF THE PRODUCTS OF COMBUSTION
FROM GAS & OTHER LIGHTS to be as follows:-
The light is placed within a glass enclosure, or structure, which is fixed to the
wall of the room, or to a chimney. This structure is closed at the top and sides
thus preventing the escape of noxious matters into the room, but it communicates
with the outside of the room or with the inside of the chimney, either by an
aperture or by tubing, either one piece or more, going through the wall. The glass
structure is open at the bottom, (but closed elsewhere) so as to admit of the
entrance of air, but the air being heated rises and escapes from the structure
through the wall. The structure during the day is covered in, or enclosed by
folding doors of ornamental work, to make an ornament for the room, but at night
they are swung back resting against the wall, or chimneys.

page_text: I, STEPHEN FRANCIS SMITH of Brunswick House, 309 Holloway Road
London N. Physician, do hereby declare the nature of my invention for AN
APPARATUS FOR CARRYING OFF THE THE PRODUCTS OF COMBUSTION FROM GAS AND
OTHER LIGHTS, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement :-
The apparatus, S, within which the light L is fixed, is a glass structure, S, or
enclosure, composed of one or more pieces of glass standing up on a bracket or
brackets, B, fixed to the wall or chimney W, either close to the wall or chimney W,
as in figure 1, or the most of the structure, S, standing a slight distance from the
wall or chimney W as in figs 2 and 3. The difference in shape and distance from
the wall or chimney W being due to option of user or peculiarities of draft through
wall or chimney W. The structure S is closed to the room at the top and sides
thus preventing the escape of noxious matters into the room, but it communicates
directly with the outside of the room, or the inside of a chimney through an
aperture A, through which goes metal tubing T either one or more pieces, according
to draft or downdraft. The glass structure, S is open at the bottom (but closed
elsewhere except as aforesaid) so as to admit of the entrance of air, but the air
being heated, rises and escapes from the aperture A, which is at the top of the
structure, S, the light, L, being at the bottom. The structure S, which may be
made of various artistic paterns, is covered or enclosed during the day by folding
doors of ornamental work 0, as in fig 4, but at night the doors are swung back
resting against the wall or chimney W. The bracket which supports the structure S
may also be used to carry the light as in figures 2 & 3 but I make no claim to a
bracket except in connection with this closed structure.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I'declare that what
I claim is
1st A glass structure S, composed of one, or more pieces; closed at the top and
sides to the room, but communicating directly through an aperture A in the wall
or chimney W., (to which it is fixed by a bracket or brackets B,) with the outside
of the room or the inside of a chimney, as aforesaid.
2nd The ornamental folding doors O, covering the structure S by day but
swinging back against the wall to shew the light by night.
