PROVISIONAL SPECIFICATION.
An Improved Smoke Burning Fire-place for Houses.
JOHN HANDSLEY DALES of No. 45 Lofthouse Place Leeds in the County of
York, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists of an improved fire-place which can be used as an ordinary
open fire-place or as an open grate fronted stove or closed fire-place in which
latter form the products of combustion and all smoke and gases from the fuel used
are caused to pass through the incandescent portion of the fire and thus produce a
perfect smokeless combustion. In carrying out my invention I provide a fire
place with front bars as ordinarily and by preference a solid bottom. At the back
of the fire place and at or near the bottom I make a narrow opening or flue either
partly or right across the fire place. This bottom flue passes up behind the fire
back and joins the upper main flue a little above the top of the fire back. The
ordinary flue is provided for the top of the fire and this flue is provided with a
door or flap for closing it in a similar manner to an ordinary soot damper such as is
used in a register grate. The said door or flap is so placed that when it is pulled
forward it shuts the ordinary top flue of the fire and when it is pushed back for
opening the top flue it falls onto the opening of the bottom flue and closes it.
Thus either top or bottom flue may be made to serve for carrying off the products
of combustion from the fire and in order to cover the top of the fire when the
bottom flue is in action and to force the gases to pass into the bottom flue by the
suction of the chimney, I provide a second door or lid which covers the whole of
the top of the fire and forms a sort of stove top leaving only the bars or whatever
space is between them for the ingress of air to support the combustion of the fuel.
When out of use the fire lid or cover stands in front of the flue door or flap
which is covering the top opening of the back flue. By lifting the fire lid and
pushing back the flue lid the top flue is opened and the fire uncovered and the
result is that of an ordinary open fire place and by putting down the fire cover
and pulling the flue door forward the top flue is closed and the bottom flue opened
and the result is that of an open fronted stove with a suction through the lower
portion of the fire which will thus consume all smoke.
For the sake of clearness I refer to the accompanying drawings in which, Fig. 1 is a
vertical section, Fig. 2 is a front elevation and Fig. 3. a plan in section through the
chimney breast, of a fire place according to the invention. All the letters refer to
the same parts in the different figures. (a, a, a, a) are the fire bars as ordinarily,
(b) is the solid bottom, (c) is the fire back, (d) is the bottom flue, passing up behind
the fire back and out into the top flue (e). The register casting is shewn at (f).
The fire cover or lid is shewn at (g) and the top flue flap or door is shewn by (h).
The full lines shew the fire place in position for consuming the smoke and the
dotted lines shew the lids or flaps in position as an ordinary fire place the dotted
arcs shewing the motion of the lids or flaps.
Adjusting screws or racks can be applied to the top flue lid for regulating the
opening of the same at any time when the fire lid is down, and thus to regulate
the draught through the bottom flue when in action.
In applying the invention to kitchen fire places the boiler or oven flues can be
utilised.

An Improved Smoke Burning Fire-place for Houses.
JOHN HANDSLEY DALES of No. 45 Lofthouse Place Leeds in the County of
York Civil Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention consists of an improved fire-place which can be used as an
ordinary open fire-place or as an open grate fronted stove or closed fire-place in
which latter form the products of combustion and all smoke and gases from the
fuel used are caused to pass through the incandescent portion of the fire and thus
produce a perfect smokeless combustion. In carrying out my invention I provide
a fire place with front bars as ordinarily and by preference a solid bottom. At
the back of the fire place and at or near the bottom I make a narrow opening or
flue either partly or right across the fire place. This bottom flue passes up behind
the fire back and joins the upper main flue a little above the top of the fire back.
The ordinary flue is provided for the top of the fire and this flue is provided with
a door or flap for closing it in a similar manner to an ordinary soot damper such is
used in a register grate. The said door or flap is so placed that when it is pulled
forward it shuts the ordinary top flue of the fire and when it is pushed back for
opening the top flue it falls onto the opening of the bottom flue and closes it.
Thus either top or bottom flue may be made to serve for carrying off the products
of combustion from the fire and in order to cover the top of the fire when the
bottom flue is in action and to force the gases to pass into the bottom flue by the
suction of the chimney I provide a second door or lid which covers the whole of
the top of the fire and forms a sort of stove top leaving only the bars or whatever
space is between them for the ingress of air to support the combustion of the fuel.
When out of use the fire lid or cover stands in front of the flue door or flap which
is covering the top opening of the back flue. By lifting the fire lid and pushing
back the flue lid the top flue is opened and the fire uncovered and the result is
that of an ordinary open fire place and by putting down the fire cover and pulling
the flue door forward the top flue is closed and the bottom flue opened and the
result is that of an open fronted stove with a suction through the lower portion of
the fire which will thus consume all smoke.
For the sake of clearness I refer to the accompanying drawings in which Fig. 1
is a vertical section, Fig. 2 is a front elevation and Fig. 3 a plan in section through
the chimney breast, of a fire place according to the invention. All the letters
refer to the same parts in the different figures. (a, a, a, a) are the fire bars as
ordinarily, (b) is the solid bottom, (c) is the fire back, (d) is the bottom flue passing
up behind the fire back and out into the top flue (e). The register casting is
shewn at (f). The fire cover or lid is shewn at (9) and the top flue flap or door
is shewn by (h).
The full lines shew the fire place in position for consuming the smoke and the
dotted lines shew the lids or flaps in position as an ordinary fire place, the dotted
arcs shewing the motion of the lids or flaps.
Adjusting screws or racks can be applied to the top flue lid for regulating the
opening of the same at any time when the fire lid is down, and thus to regulate
the draught through the bottom flue when in action.
In applying the invention to kitchen fire-places the boiler or oven flues can be
utilised.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what
I claim is :-
The fire covering lid (g) in combination with an ordinary open fire soot lid (h),
5 and an opening into the closed flue in the fire back or bottom, substantially as
shewn in the drawings and as described for the purpose named.
