Improvements in Appliances for Drying Roofing Tiles, Bricks, and
the like.
...
I, LEO NEFKENS, of Blerick, near Vendo, Holland, Manufacturer, 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:-
-
The subject of the present invention is a chamber or chambers for drying
roofing tiles, bricks, and the like, and the invention mainly consists in the roof
being formed as a desk or saddle roof, the gable stone of which consists of a
moulded brick of either desk or saddle shape, and provided with small channels
through which air may pass from the inside to the outside.
-
In employing the moulded brick, special constructions of the roof are required,
so that same is provided with an air insulating space, through which air, coming
from the chamber, may escape into the open, and moisture or the like is pre-
vented from entering the drying chamber from the outside.
When used in connection with a desk roof, the moulded brick is hollow in the
centre, and the cavity is filled with peat litter, or other heat non-conducting
material so as to insulate the interior of the drying chamber. This is necessary,
in the case of desk roofs, as one side of the brick is protected against the outer air,
only by a thin boarding.
In the chamber itself, grates or the like are arranged, upon which the material
to be dried is placed, whilst above or below the grating or floor, or directly in the
material, heating pipes are disposed.
The invention is illustrated in the annexed drawings, in which,
Figure 1 shews the drying chamber with a desk roof, whilst
Figure 2 shews the same with saddle roof.
Figures 1", 1, and 2", 2b, are sections and views from above, of the gable stones
or bricks used in connection with these roofs.
Referring now to the drawings, and more particularly to Figures 1, 1º,
and 1, a a are the drying chambers, which are provided with gratings b b near
their floors, and underneath same are disposed the heating pipes c.
The roof of the chambers a a is of desk shape, as also is the gable stone d.
This gable stone d at its shoulders e possesses fine channels f, through which
the air from the drying chambers may escape to the outside, and without allowing
cold air to penetrate from the outside into the interior of the chambers. The
gable stone or brick, at its centre is provided with a cavity g, containing peat
litter, or the like, the two outer sides of the brick being held together by means
of a screw h.
The roof of the chambers a a is provided with insulating spaces i, formed
by first providing the roof with wooden boardings. The insulating spaces may
be filled with tar, or other material.
In the case of the desk roof, the ventilating arrangement is of course applied
only on one side, the roof itself being covered with roofing felt, or the like, so

page_text: that it offers complete security against moisture. The wooden boarding k is
arranged in such a manner that one side covers the other, and so prevents moisture
from getting into the channels f from the outside, the air nevertheless being
carried into the open, underneath the boarding. The boarding k is required only
on the one side.
Referring now more particularly to Figures 2, 2ª, and 2b, the roof may be made
of saddle shape, the moulded brick or gable stone, being also made saddle shaped,
and having shoulders e and channels fon both sides. The roof is double boarded,
whereby insulating spaces are formed, but in this case the boardings mutually
cover each other, so that the warm air may get into the open, from underneath
the boarding, without any moisture getting into the channels f.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a chamber or chambers for drying roofing tiles, bricks, and the like, the
employment of roofs of desk or saddle shape provided with boardings, whereby
insulating spaces are formed; and a gable stone consisting of a moulded brick of
clay, loam, plaster of Paris, or the like, provided with fine vertical channels in
its protruding ends, through which heated air may escape; substantially as
set forth.
2. In a chamber or chambers for drying roofing tiles, bricks, and the like, as
characterised by the preceding claim, the arrangement of the boarding of the
roof above the gable stone, by which the edges of the roof mutually overlap each
other, and form shafts, through which hot air may pass from the chamber or
chambers, and moisture is prevented from entering the chamber or chambers;
substantially as described.
3. In a chamber or chambers for drying roofing tiles bricks, and the like, as
characterised by Claim 1, providing the gable stone of desk shaped roofs with
a cavity containing a heat non-conducting substance, as peat litter, or the like,
for the purposes set forth.
