PROVISIONAL SPECIFICATION
Improvements in or applicable to Open Fire Places.
I, CHARLES WHITFIELD, of Union Street, Kettering, in the County of
Northampton, Engineer, do hereby declare the nature of my said invention to be
as follows:-
The object of this invention is to so improve an open fire place that it shall give
all the heating effect of an enclosed stove and considerably promote the ventilation
of the room in which such fire place is situated.
In performing my invention I enclose the top of the fire by a suitable plate or
casting forming a canopy. over the fire and enclose the opening leading into the
chimney flue by extending upwards the back of the plate or casting and to take off'
the smoke and products of combustion from the fire I carry up from the canopy
a metallic tube by preference through the canopy and flue enclosing plate or form
the same behind the back plate. In this manner 1 partially enclose the fire without
materially interfering with the cheerful appearance of an open and visible fire
whilst I obtain the extra heating effect of the top plate or canopy and of the flue
and thus approximate to the effectiveness of an enclosed stove. In some cases I
hinge the canopy to the back plate at a suitable angle so as to form a space behind
it for banking up the fresh fuel and in this case I take off the products through the
front edge of the canopy which is formed as a tubular opening leading into the
flue.
I further produce a great difference in the barometrical pressure between the flue
and the room which will improve and considerably facilitate the position of the
latter.

COMPLETE SPECIFICATION.
Improvements in or applicable to Open Fire-places.
I, CHARLES WHITFIELD, of Union Street, Kettering, in the County of
Northampton, Engineer, do hereby declare the nature of my said invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement: -
The object of this invention is to so improve an open fire place that it shall give
all the heating effect of an enclosed stove and considerably promote the ventilation
of the room in which such fire place is situated or an adjacent compartment.
On the accompanying drawing Fig. 1 is a front view and Fig. 2 a side sectional
view of an open fire place or grate having my improvements applied thereto and
Figs. 3 and 4 are similar views of modifications of my invention.
In performing my invention I enclose the top of the fire by a suitable plate or
casting a forming a canopy over the fire and I enclose the opening leading into the
chimney flue by a plate 6 as illustrated in Figs. 1 and 2.
To take off the smoke and products of combustion from the fire I carry upwards
from the canopy a by preference breeches pipe cand connect the single branch
pipe e from the same at the top to the plate b. Or I carry up the back d of the
plate or casting (forming the canopy) as seen in Fig. 3 and so form the flue behind
such back plate. In this manner I practically enclose the fire without materially
interfering with the cheerful appearance of an open and visible fire, whilst I obtain

page_text: the extra heating effect of the top plate or canopy and of the flue and thus approxi-
mate to the heating effectiveness of an enclosed stove. e' is a swivel damper for
regulating the draught.
I hinge the front portion of the canopy in position so as by turning up the same
to facilitate the feeding of the fire place with fresh fuel from time to time-or a
portion of the canopy may be caused to slide back or to be capable of otherwise
opening for this purpose.
As illustrated in Fig. 4 I sometimes form a receptacle for fresh fuel behind
my improved fire place and which I mount upon pivots or hinges f³ so as to
be drawn forwards when required to the position illustrated in Fig. 4. to be
recharged and thus by having an air tight hinged or other lid applied to the
mouth of the receptacle I form a self-feeding apparatus-and take off the smoke
and products through side flues.
In Figs. 1 and 2 I shew a ventilating pipe applied to the chimney breast ; of
my improved enclosed fire place such pipe leading from the top or any other level
in the apartment or in any adjacent apartment and opening into the flue and which
being provided with a regulator and damper k as illustrated thus forms an adjustable
means of ventilating which is impossible with an open flued fire place.
I wish it to be understood that I do not confine myself to the precise form
of top or canopy to the fire place nor to the distance or height of the same
above the fire as these may be considerably varied without departing from my
invention.
-
Having thus particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what 1
claim is :-
1st. In an open fireplace or grate the employment of an enclosing top or canopy
in combination with a flue enclosing plate and intermediate pipe or passage for
enabling the smoke or other products to pass into the main flue substantially as and
for the purposes hereinbefore described and illustrated on the accompanying
drawing.
2nd. The improved apparatus detailed in the preceding claim in combination
with a fuel supplying device substantially as hereinbefore described and illustrated
in Fig. 4 of the annexed drawing.
Dated this 11th day of December 1890.
