PROVISIONAL SPECIFICATION.
A New or Improved Device for Preventing Chimneys Smoking.
I, JOSEPH JOHN BARTON, of 122 St. John Street Road London E.C. Builder
do horeby declare the nature of this invention to be as follows :-
This invention relates to an arrangement intended to prevent smoke being blown
down the chimney into the room.
The arrangement consists of a device which is attached to the bars of the grate,
in the form of a curved plate approximately semicircular in cross section. The
plate projects almost to the bottom of the grate and curves towards the back over
the fire, curving upwards at the end to an approximataly vertical position. This
forms a hot air chambor, thus directing a column of hot air up the chimney,
carrying the smoke with it and helping to consume the same. A strong current is
thus produced which effectually provente any down draught.
In order to reuder the devico more effective a fan of mica, tin or other suitable
material may be placed at the upper end of the plate. For firoplaces where the
height of the opening is great, I fix a tubo on to the top of the curved plate
projecting upwards for a suitable distance in order to direct the stream of hot air
better and make it more powerful. Hooks of any ordinary description are
employed to fasten it on to the bars so that it can be removed or replaced at any
time without difficulty, a handle being furnished for that purpose.
The device may be constructed of tin, iron, brass or other material, and can be
cast in an ornamental form, or made in any other suitable manner.

COMPLETE SPECIFICATION.
A New or Improved Device for Preventing Chimneys Smoking.
I JOSEPH JOHN "BARTON of 122 St. Johns Street Road, London, E.C. Builder,
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 relates to an arrangement intended to prevent smoke being blown
down the chimney into the room.
The arrangement cousists of a device which is attached to the bars of the grate,
in the form of a curved plate approximately semicircular in cross section. The
plate projects almost to the bottom of the grate and curves towards the back over
the fire, curving upwards at the end to an approximately vertical position. This
forms a hot air chainber directing a column of hot air up the chimney carrying the
smoke with it and helping to consume the same. A strong current is thus provided
which effectually prevents any down draught.
In order to render the device more effective a fan of mica tin or other suitable
material may be placed at the upper end of the plate. For fireplaces where the
height of the opening is great, 1 fix a tube onto the top of the curved plate
projecting upwards for a suitable distance in order to direct the stream of hot
air better and make it more powerful. Hooks of any ordinary description are
employed to fasten it onto the bars so that it can be removed or replaced at any
time without difficulty, a handle being furnished for that purpose.

page_text: The device may be constructed of tin, iron, brass or other material, and can be
cast in an ornamental form, or made in any other suitable manner.
In order that the invention may be more clearly understood reference is had to
the accompanying drawings in which
Fig. 1 is a section and Fig. 2 a front elevation of a fireplace fitted with my
invention,
Fig. 3 is a section of the device with the additional tube, and
Fig. 4 is a plan showing the fan attached.
The curved plate A, which is of swan neck form, pointing vertically at both
ends a and a', is furnished with the hooks B on each side which as shown in Fig. 1,
are placed over the top or other bar of the grate, holding the plate securely in
position. A chamber of curved form is thus produced, which as the air in it
becomes heated draws a constant current from its lower end a and directs it up the
chimney from a point a little above the fire. The flames, smoke and heated air
from the fire will thus be drawn towards the centre and ascend in a narrow column,
with greatly increased force. The handle C is furnished by which the device can
be readily removed or replaced when desired.
In some cases a supplementary tubo D may be employed fitted on the end a' and
projecting upwards into the chimney for some distance. For convenience in fixing,
the top of the plate A may be furnished with a ring or loop d'in which the tube D
is placed, a collar on the tube supporting it.
As shown in Fig. 4 a small fan E of the kind commonly used with lamps for the
production of a better draught, is fitted at the top a'. This may be used with or
without the additional tube D.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
°
(1.) A device for the prevention of smoking chimneys, consisting of a curved
plate approximately semicircular in cross section, fitted to the fire place and
forming a chamber directing a current of air up the chimney, substantially as
described.
(2) A dovice for preventing chimneys smoking, consisting of a plate approxi-
mately semicircular in cross section and of swan neck form, furnished with hooks
for attachment to the bars of grate and a handle for removal or replacement,
substantially as and for the purposes specified.
(3.) In combination with the device above claimed, a detachable tube fitted on
top of the said chamber substantially as and for the purposes specified.
(4.) A device for the prevention of smoking chimneys, consisting of a plate
