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 IMPROVED APPARATUS FOR CARRYING OFF THE PRODUCTS OF THE COMBUSTION
OF, GAS, OR OTHER LIGHTS to be as follows:-
The light is placed within a structure composed of one or more pieces of glass,
metal, and mica, or of glass and metal, or of glass and mica, or other suitable
material in combination with glass. This structure is fixed to the wall of the
room or to a chimney. It is closed at the top and sides thus preventing the escape
of noxious matters into the room, but it communicates by an opening near the top
with the outside of the room or with the inside of a chimney either by an aperture
or by tubing or by other suitable closed pipes or structure, either by one piece or
more going directly through the wall; or the pipe after leaving the structure
which holds the light may go some distance up the wall and then be carried
through the wall or into the chimney. The top of the structure may be square or
flat on the top, or rounded, but preferably flat so that a vessel may rest upon it to
be used for boiling or cooking. The structure is open at the bottom so as to allow
of entrance of air, which, being heated, rises and escapes through the aperture near
the top. The structure which may be made of various patterns, shapes and
designs, may be covered in during the day by ornamental folding doors, which
may be swung back at night against the wall, and in case the pipe is carried some
distance up or across the wall it may be covered over by mirrors or ornamental
work. A damper may be placed in the pipe close to the structure or further off
to prevent down draft or regulate the draft. Should it be necessary for the benefit
of better light, or because of peculiarity of draft or otherwise the air of the room
may be allowed to enter the structure through a small or narrow space between
the bottom and the top of the structure, made by a vertical or horizontal separa-
tion of the segments of which the structure is composed, the upper segment, (if
the separation be made horizontally), overlapping the lower one but a space
intervening between the opposing surfaces, the two segments being kept fixed the
one partly within the other. by suitable brackets bands or other supports.

I, STEPHEN FRANCIS SMITH of Brunswick House 309 Holloway Road, London N
Physician 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:―
The light is placed within a structure S composed of one or more pieces of glass i
metal and mica or of glass and metal or of glass and mica or other suitable
material in combination with glass. This structure is fixed to the wall of a room
or to the chimney. It is closed at the top and sides thus preventing the escape of
noxious matters into the room, but it communicates by an opening A' near the top
with the outside of the room or with the inside of the chimney by tubing or other
'suitable closed pipes or structure either by one piece or more going directly
through the wall W, or the pipe after leaving the metal part of the structure M
which holds the light may go some distance up the wall and then be carried
through the wall W or chimney. The top T of the structure M which fits over the
glass part G may be made of metal and may be closed by a cup-shaped lid, or lid
of other shape, which may be either permanent, or may be taken out completely or
swung back on a pivot, P, or hinge joint. The top T of the structure is left .flat
or rounded but preferably flat so that a vessel may rest upon it to be used for
boiling or cooking. The structure is open at the bottom so as to allow of entrance
of air which being heated rises and escapes through the aperture A near the top,
but should it be necessary for better light or because of peculiarities of draft or
otherwise the air may be allowed to enter the structure also through a small or
narrow space between the glass, G, part of the structure and the top or metal
part M; the metal part M of the structure being made a little larger than the
lower or glass, G, part which fits into it.. The top or metal part, M, is made to
open laterally to admit the glass, G, or to be raised with a portion of the tubing, t,
from joint, J, or to be raised at its aperture A, or the glass if straight may be
slipped down through it; or it M may be taken quite off and the glass G then
put in its place and the metal M part adjusted to it and attached at A to the
tubing t. Again, the gas jet, g, may be turned aside and the glass part, G, put in
its place and then the gas jet, g, brought back in its place again. The structure S with
its M, and T & tubing t, may be supported on a bracket or gas jet, g, which
is inserted directly, in the wall or inserted into a block B, the block B helping to
support the tubing t. The structure S, with its top M & T may be made in various
shapes & patterns and designs and covered in during the day by ornamental
folding doors which may be swung back at night against the wall, and in case the
pipe or tubing t, is carried some distance up or across the wall it may be covered
over by mirrors or ornamental work. Should it be necessary to prevent too rapid
rush upwards of heated air, a gas oven O may be placed over the structure the
heated air being sent into it before escaping through the wall W being sent into.it
through the tubing t; or the oven, O, may be interposed between the bottom or

page_text: glass portion, G, of the structure and the upper or metal portion M, the air entering
directly into the bottom of the oven, O, from the glass, G, part of the structure
and escaping from the metal part, M, placed on the top of the oven O, through the
wall; the oven O and the metal part, M, thus forming the top part of the
structure and being then included in the structure for carrying off the products of
combustion.
A damper, D, may be placed in a suitable position in the pipe or tubing, t, to
prevent down draft.
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
A close structure but open at the bottom holding a light and so composed as
berein before described as to carry off the products of combustion out of a room,
claiming the structure and its system of tubing through the wall and when
necessary the interposition of a gas oven into the composition of the structure and
forming an integral portion of the same.
