I, WILLIAM FISKEN, of Stamfordham, in the County of Northumber-
land, Presbyterian Minister, do hereby declare the nature of the said.
Invention for "IMPROVEMENTS IN APPARATUS FOR HEATING OR WARMING
BUILDINGS, ALSO APPLICABLE FOR COOKING PURPOSES," to be as follows:-
The object of this Invention is to effect an economy in the con-
sumption of fuel in stoves used for heating or cooking by utilizing a large
per centage of the heat generated. This result I obtain by combining
with the stove or fire-place a series of flat tubes in such manner that the
smoke and hot gases from the fire will have to pass through the tubes
on their way to the chimney. The tubes are placed side by side but at
a short distance apart to allow of air circulating between them and
taking up the caloric from the escaping gases of combustion and
distributing it through the apartment to be warmed. The tubes are
arranged between and secured to two tube plates, the one tube plate

page_text: facing the fire the other the smoke-way or chimney. These tube plates
are of iron or other fireproof material. The flat tubes are made of sheet
or cast iron or other metal. A baffle plate may be used above the fire
to protect the tube plate and tubes from the direct action of the fire.
In each tube plate there are formed long narrow slots corresponding
to the sectional figure of the flat tubes and the slots or openings are
surrounded by flanges on the side next the tubes to receive the ends of
the flat tubes which are slipped on the flanges corresponding to each
other on opposite faces of the tube plates and are secured thereto by
wedges or otherwise.
The heating power of the apparatus is increased by increasing the
number of tubes and extending the tube plates and fire-space, or the
tube plates can be made in sections and pairs, the heating power of the
apparatus may then be increased by increasing the number of sections
and their corresponding tubes.
The heating tubes may be situate either within the apartment to be
heated or the air may be admitted to the heating spaces between the
tubes, and then conducted into the apartment.
For heating dwelling houses the apparatus is arranged to stand in the
the ordinary fire-places.
Fitted to the face of one of the tube plates is a slide or regulator
slotted to correspond to the slots and spaces on the tube plate. By
means of a lever this slide may be moved to open entirely the spaces or
close them partially in proportion to the amount of heat required to pass
through the tubes, and also to cause the hot gases to be more equitably
spread over the face of the tube plate next the fire. The tube plates are
secured together by means of rods.
The flat tubes may either lie horizontally from the side of the
fire-space or they may stand vertically above the fire, as found most
convenient. When placed vertically air guides are used to cause the air
to pass horizontally between the tubes.
When applying the apparatus to cooking the series of flat tubes are to
be enclosed in a brick or iron chamber of sufficient size to contain the

page_text: viands or articles to be cooked, and fitted with a door in front. This
chamber is readily heated up to and maintained at the cooking degree
by allowing little or no air to enter the tubes but that which passes
through the fire. This is done by closing the fire-place above the grate.
The heat will be regulated by the slide or regulator already described.
