PROVISIONAL SPECIFICATION.
An Improved Blower and Draught Regulator for use in Open
Fire-places.
ROBERT JAMES LEE 39 Gunterston Road West Kensington, London Doctor
of Medicine of Cambridge do hereby declare the nature of this invention to be as
follows:-
A combination of two parts, one to fit in front of the fire-place, closing to some
extent the area above the bars and acting as an ordinary blower.
The second part acts more or less horizontally across the mouth of the chimney,
and regulates the up-draught from the fire into the chimney.
These parts are connected by hinges or otherwise to one another, and the second
part can be raised or lowered by means of a rod, or bar or other method, passing
through the first part and workable from in front of it.
The two parts form one apparatus which can be easily applied to open fire-
places.
COMPLETE SPECIFICATION.
An Improved Blower and Draught Regulator for use in Open
Fire-places.
ROBERT JAMES LEE 39 Gunterston Road West Kensington London, W.
Doctor of Medicine, 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 is a combination of two parts which are connected with one
another and form one apparatus, which can be applied easily to open fire-places.
The first part called the blower closes to some extent the area of the fire-place
above the bars, and acts as an ordinary blower.
The second part called the regulator acts more or less horizontally across the
mouth of the chimney and regulates the up-draught from the fire into the chimney
according as being raised or lowered, it tends to open or close, increase or diminish,
the passage from the fire-place into the chimney.
These two parts are connected by hinges or otherwise so that the second, the
regulator, can be raised or lowered by means of a rod, bar, ratchet, or chain, one
end of which is attached to the regulator, the other end is carried through the
blower so as to be reached from in front of it, and thus the raising or lowering of
the regulator permitted. Or this movement of the regulator may be effected by
any well known contrivance. The blower and the regulator may be made of thin
sheet iron or other metal: their shapes being adapted to the size and shape of the
front and the back of the fire-place respectively.
The blower may be fixed to the fire-place by small hooks, screw nuts or other
simple contrivance; and the two parts may be hinged by stiff wire passed through
the turned-down edges of the plates or other simple form of hinge may be used.
By the action of the blower the combustion of such fuel as coke or anthracite may
be effected, and smoke be prevented. By the action of the regulator the amount of
air passing up the chimney is diminished, and thus excessive ventilation of an
apartment is provided against, and loss of heat by excessive updraught in the
chimney prevented.
In Fig. 1, an ordinary register stove is represented fitted with my invention,

page_text: The blower is indicated by B; and takes the form of a semicircular plate fixed
to the margin of the fire place, so as to close the area above the top-bar, to within
about 6 inches distance from it; and is held in position by two screw nuts and a
button.
The regulator in Fig. 1. is shewn by the plate R in dotted outline; and hinges
or passes horizontally back from the blower across the inlet into the chimney.
In Fig. 2 the regulator R is shewn quite low, so that a narrow space only
intervenes between it and the back of the fire-place. It is indicated half raised by
dotted lines. The ratchet or chain by which the regulator is lowered or raised is
indicated by d.
Fig. 3 shews the apparatus removed from the fireplace view.
B is the front or blower: R the adjustable damper, plate, or regulator: D is the
ratchet or chain by which means adjustment is effected.
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
A combination of a blower to promote combustion, with a regulator to regulate
the up draught so as to form one apparatus which can easily be applied to any
open fire-place substantially as described.
