I, NICOLAUS HEID, of. Stockeran, Lower Austria, Engineer and Manufacturer,
do hereby declare the nature of this invention to be as follows:
The wire-net.floors-used-hitherto for malt-kilns have several disadvantages such
as the small area of delivery passage through them (about 35%) and the unevenness
of their surface which is an important defect.
They have to be provided with a supporting forged iron grating, but the
numerous connections of the bars. of the grating render-it very difficult to obtain
an even surface, especially as: the pressure to which the wires are subjected in
manufacturing the network causes it to become warped.
According to this invention the floor is made of specially shaped rolled bars, and
this construction entirely obviates the defects mentioned above by increasing the
active area more than one half, providing a strong floor without any supporting
grating being required, and a perfectly, even. drying surface; and since the
expensive grating is entirely dispensed with, the cost of the floor is much reduced.
In the accompanying drawings Figs. 1 to 3 shew in side view.section and plan
part of a kiln Hoor constructed according to this invention;- Figs. 4 and 5 are
respectively a plan and a side elevation of the structure carrying these gratings.
As shewn, each grating is formed of; iron bars a rolled with the head portion a¹
widened so that when they are put together they form between them continuous
slots, without the interruptions and indentations which the wire net present at the
places where the wires interlace.
+ '
These iron bars a have holes near their ends and are strung on rods b with
intermediate washers a keeping them at the proper intervals apart.
In order to firmly secure the bars a on the rods b, the projecting ends of the rods
are rivetted or burred over by hammering.
As shewn in Figs. 4 and 5 the gratings I, II, III, IV, constructed as above
described, are supported where they meet, and also with advantage in their middles,
by iron cross girders d, resting on longitudinal girders arranged. on both sides. of
the kiln.
These supports being made of. straight bars, they are easily fixed in a horizontal
plane, so that the gratings laid on them have a perfectly even surface, which is not
subject to distortion, as the grating can carry considerable weight and the bars a
are not liable to become warped.

Improvements in Floors for Malt-kilns.
I, NICOLAUS HEID, of Stockerau, Lower Austria, Engineer and Manufacturer,
0 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 wire net floors used hitherto for malt kilns have several disadvantages such as

page_text: the small area of delivery passage through them (about 35%) and the unevenness
of their surface which is an important defect.
They have to be provided with a supporting -forged iron grating, but the
numerous connections of the bars of the grating render it very difficult to obtain
an even surface especially as-the pressure to which the wires are subjected in
manufacturing the network causes it to become warped.
According to this invention the floor is made of specially shaped rolled bare,
and this construction entirely obviates the defects mentioned above by increasing
the active area more than one half, providing a strong floor without any supporting
grating being required, and a perfectly even drying surface; and since the
expensive grating is entirely dispensed with, the cost of the floor is much reduced.
In the drawings accompanying my Provisional Specification, Figs. 1 to 3 shew
in side view, section and plan part of a kiln floor constructed according to this
invention; Figs. 4 and 5 are respectively a plan and a side elevation of the structure
carrying these gratings.
$
As shewn, each-grating is formed of, iron bars a rolled with the head- portion a¹
widened so that when they are put together they form between them continuous
slots, without the interruptions and indentations which the wire net present at the
places where the wires interlace.
2.
These iron bars, a have holes near their ends and are strung on. röds' & 'with
intermediate washers c keeping them at the proper intervals apart.
In order to firmly secure the barsa on the rods b, the projecting ends of the rods
are rivetted or burred over by hammering.

As shewn in Figs. 4 and 5 the gratings I, II, III, IV, constructed as above
described, are supported where they nect, and also with advantage in their middles,
by iron cross girders d, resting on longitudinal girders farranged on both sides
of the kiln, :
These supports being made of straight-bars, they are easily fixed in a horizontal
plane, so that the gratings laid on them have a perfectly even surface, which-is-not
subject to distortion, as the grating can carry considerable weight and the bars are
not liable to become warped.

Having now particularly described, and ascertained the nature of this inven
tion and in what manner, the same, is to be performed, declare that what I
claim is :-
1.A kiln-floor consisting of parallel bars with widened heads strung on rods
passing through holes of the bars with intermediate washers or distance pieces,
substantially as and for the purpose set forth;
2. Supporting a kiln floor such as is above referred to on cross girders resting on
longitudinal girders at the sides of the kiln, substantially as described
