PROVISIONAL SPECIFICATION.
Heat Reflector for Domestic Fire-places.
I GOTTLIEB WALTER EVERTH 3 Love Lane Eastcheap E.C. Merchant do
hereby declare the nature of this invention to be as follows:-
A plate made of non combustible material mostly metal and asbestos has several
parallel and horizontal slits cut in it, the slips thus cut being bent forwards and out-
wards so as to form rigid flaps at right angles to the plate. The plate which can be
made of any size or shape to suit the chimney to be fitted, is fixed over the chimney
opening. The smoke ascends the chimney through the apertures in the plate but.
the bent forward flaps prevent the heat ascending and eject it into the room.

GOTTLIEB WALTER EVERTH.
I, GOTTLIEB WALTER EVERTH, Merchant, of 3, Love Lane, Eastcheap, in the
City of London, 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 has for its object to economise the heat produced by the combustion
of fuel in domestic fireplaces.
For this purpose I place in the flue leading to the chimney or in the chimney
itself a perforated plate of iron, asbestos or other practically fire-proof material,
preferably at an angle of about 45 degrees, so as to obstruct the passage of the
gases and reduce the area for the escape of the products of combustion up.
the chimney.
The shape and size of the said plate depend, of course, on those of the fireplace.
or flue, and the perforations are preferably horizontal slots placed parallel to each
other, each slot being combined with a narrow baffle-plate formed from the material
cut out of the slot.
In the accompanying drawings Fig. 1 is a vertical section and Fig. 2 a front.
view of an approximately rectangular heat reflector embodying my invention.
The material of the reflector plate is "asbestos aluminium mill board or other
suitable asbestos composition and sheet metal, the latter being sandwiched between
two thin sheets of the former.
a, a, a, are parallel horizontal slots, and the baffle plates formed by turning the.
blanks outward on their lower edge. These baffle plates or strips may form any
desired angle to their base; they may be separate from their base and adjustable to.
vary their angle at will when required.
In the drawing the baffle plates or deflecting strips are arranged along the lower
edge of the slots, but they may be placed along their upper edge, and the per-
forations or slots are not necessarily horizontal, but may be curved or placed at
any desired angle, and they may be varied in size, shape and number. The heat.
reflector is not necessarily made from a flat plate, but may be concave, and if it is.
[Price Bil.]

page_text: made from cast metal, the flaps may be formed in the casting. The outline of the
heat reflector may be a semi-circle or other suitable figure, instead of a rectangle.
The heat reflector may be secured to the sides of the flue or to the chimney plate
by means of lugs and screws, clips, or other suitable devices in such a manner that
it can be removed without difficulty for sweeping the chimney. Or it may be
adapted to turn on hinges.
If a fireplace is provided with a heat reflector as described above, the gases of
combustion arising from the fire will be deflected by the baffle plates and the
area for the passage of the gases up the chimney will be contracted, in conse-
quence of which a portion of the heat will be reflected into the room, the volume
of air drawn up the chimney will be reduced, the fire will burn more uniformly,
and the fuel will be used more economically than would be the case without a
reflector.
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 heat reflector for domestic fire-places, consisting of a reflector plate
provided with slots or perforations and baffle plates, substantially as described and
for the purpose specified.
2. A heat reflector for domestic fire-places, consisting of a plate provided with
slots and with baffle plates formed from the blanks cut out of the slots, substantially
as described.
3. A slotted heat reflector plate composed of sheet metal and asbestos aluminium
mill board or similar asbestos composition arranged as described.
4. A slotted heat reflector plate arranged and adapted to operate substantially
as described.
