1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham, in
the County of Warwick, and 322, High Holborn, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in the arrangement of dry or drying
chambers, and is designed to effect, by its peculiar construction, a considerable
saving in coal or other fuel.
In drying chambers as hitherto employed, either a large part of the heat of the
drying chamber is withdrawn by the steam being directly carried away, or the
steam is left in the drying chamber and condensed, which also causes a considerable
loss of heat.
This drawback is removed in the present invention by the moisture being
separated from the heat, whereby the above mentioned saving in fuel is effected.
In the accompanying drawings a form of construction of the improved arrangement
of drying chamber is shown in two sectional views.
The inner drying chamber is surrounded by a second inner wall y, which
consists of such material as absorbs moisture, whilst at the same time is a bad
conductor of heat.
By this means, whilst the moisture is absorbed by the inner covering material, it
passes, in consequence of the heat of the inner chamber, as steam into the space 2.
Suitably arranged air holes a and c which are preferably formed some above and
some below, cause a constant air current to be produced in the space in the direction
indicated by the arrows, so that the vapour or steam rising from the inner lining
or wall is carried away without there being carried with it any essential amount of
heat from the actual drying chamber. In order to prevent condensation in the
space, a small portion of the heat of the inner chamber is utilised for preliminarily
heating the fresh air which enters.
As a suitable material for the construction of the inner wall, ordinary bricks or
tiles are selected in such a way that thereby a saving of fuel of from 35% to 50%
is attained. If the intermediate wall.be built in accordance with the principle of
the invention of a very porous, cellular, material readily susceptible to damp
but on the other hand a bad conductor of heat, such for instance as kieselguhr
(silicious sinter), calcined kieselguhr, or the like, the useful effect is correspondingly
increased.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham in the
County of Warwick and 322 High Holborn in the County of Middlesex, 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 ascertained in and by
the following statement :-
This invention relates to an improvement in the arrangement of dry or drying
chambers, and is designed to effect, by its peculiar construction, a considerable
saving in coal or other fuel.
In drying chambers as hitherto employed, either a large part of the heat of the
drying chamber is withdrawn by the steam being directly carried away, or the
steam is left in the drying chamber and condensed, which, also causes a considerable
loss of heat.
This drawback is removed in the present invention by the moisture being
separated from the dry air, whereby the above mentioned saving in fuel is
effected.
In the drawings filed with the Provisional Specification a form of construction of
the improved arrangement of drying chamber is shown in two sectional views.
The inuer drying chamber is surrounded by a second inner wall Y which
consists of such material as absorbs moisture, whilst at the same time is a bad
conductor of heat.
By this means, whilst the moisture is absorbed by the inner covering material, it
passes, in consequence of the heat of the inner chamber, as steam into the space z.
Suitably arranged air holes a and c which are preferably formed some above. and
some below, cause a constant air current to be produced in the space z in the direction
indicated by the arrows, so that the vapour or steam rising from the inner lining
or wall is carried away without there being carried with it any essential amount of
heat from the actual drying chamber. In order to prevent condensation in the
space, a small portion of the heat of the inner chamber is utilised for preliminarily
heating the fresh air which enters.
As a suitable material for the construction of the inner wall, ordinary bricks or
tiles are selected in such a way that thereby a saving of fuel of from 35% to 50%
is attained. If the intermediate wall be built in accordance with. the. principle of
the invention of a very porous, cellular, material readily susceptible to damp
but on the other hand a bad conductor of heat, such for instance as kieselguhr
(eilicious sinter), calcined kieselgubr, or the like, the saving in fuel is correspondingly
increased.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, 1 declare that what I claim is,
An arrangement of dry or drying chambers, characterised by the inner chamber
being enclosed by a wall or partition of such material as will absorb moisture, and

page_text: by a current of air being brought into contact with the outside of said wall in such
a way as to carry away the steam arising from the wall or partition, substantially
as herein before set forth.
