PROVISIONAL SPECIFICATION.
An Improved Kiln or Drying Apparatus.
I, XAVIER CHARLES, Contractor, of Wavreille, Belgium, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a kiln or drying apparatus of the following description.
In the middle of a rectangular or square structure in brickwork or masonry is a fire
with ashpit below it. From the fire rises a flue tapering to a smaller size as it.
ascends and baving flue pipes branching off from it at angles, these pipes being
provided at the top with deflecting caps and being also furnished with dampers by
which their upper ends can be closed while branches from them leading to a central
chimney remain open.
There are also passages for entrance of air to the interior of the structure and to
flues enclosing the central fire flue. The parts described are all floored over by a
metal plate which may be perforated, and through which the central chimney
passes, and hot air tubes also pass when it is desired to transmit hot air to drying
chambers which may be erected above. When the material dried upon the floor is
not liable to be damaged, the products of combustion as well as the heated air may
ascend through the floor. But when the material to be dried is such as might be
injured by the combustion gases, the flues for these are closed at the top, only the.
hot air being allowed to pass through the floor.

COMPLETE SPECIFICATION.
An Improved Kiln or Drying Apparatus.
I, XAVIER CHARLES, Contractor of Wavreille, Belgium do hereby declare the.
nature of this invention and in what manner the same to be performed, to be.
particularly described and ascertained in and by the following statement:―
This invention relates to a kiln or drying apparatus shewn in the accompanying
drawings, Fig. 1 being a vertical section of the stove, Fig. 2 a plan at the fire grate,.
Fig. 3 a plan above and Fig. 4 an elevation of a drying chamber above the stove,
of which Figs. 5 and 6 are side views.
In the middle of a rectangular or square structure in brickwork or masonry is a
fire B with ashpit A below it. From the fire rises a flue tapering to a smaller size
as it ascends and having flue pipes D branching off from it at angles, these pipes being
provided at the top with deflecting caps and being also furnished with dampers by
which their upper ends can be closed while branches from them remain open leading
to a central chimney F having damper G. There are also passages E for entrance
of air to the interior of the structure and to flues enclosing the central fire flue,.
from which branch flues, also furnished with caps. The parts described are all
floored over by a metal plate I which may be perforated, and through which the
central chimney passes, and hot air tubes also pass when it is desired to transmit
hot air to drying chambers which may be erected above.
When the materials dried upon the floor are not liable to be damaged, the
products of combustion as well as the heated air may ascend through the floor. But
when the material to be dried is such as might be injured by the combustion gases,
the flues D for these are closed at the top, only the hot air from the pipes E and
the space H being allowed to pass through the floor.

page_text: When a perforated floor is used to dry finely granulated materials, such of the
granules as fall through into the space H slide down inclined passages C from which
they can be removed by opening external doors. The stove, so far described, may
be surmounted by a drying chamber such as is shewn in Fig. 4, K being the wall,
Na door, L the roof, F the chimney, M ventilators.
This chamber may be
supplied with heated air by pipes in the corners of the stove. The pipes D and E
are preferably made of square section with an angle of the square presented upper-
most to let any granules falling on them from the kiln slide off. An oven for
baking might be arranged either above or below the floor I.
The apparatus described presents the following advantages.
1. No heat is lost, and consequently there is great economy of fuel.
2. Owing to the concentration of the heat, there is a strong draught so that fuel
of inferior quality can be used.
3. The apparatus may be applied to dry or bake any kind of materials.
4. By means of dampers in the pipes conveying air and combustion products the
fire heat and air supply can be regulated as desired.
5. The apparatus can be varied in form and dimensions to suit different uses.
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-The kiln or drying apparatus consisting of a fire with pipes and chimney for
passage of combustion products, surrounded with air pipes, and covered by a floor,
the whole enclosed in masonry substantially as herein described.
2-In combination with the apparatus referred to in the preceding claim, a
drying chamber or several of these above the stove supplied with heated air,
substantially as described.
