BACKGR'OUND 'OF'THE''INVENTION
' FIELD 'OF THE''INVENTION
This invention relates to a block or brick for the
construction of a two-shell tile stove having an internal
shell of refractory blocks or bricks and an external shell
- of tiles.
' DE'SCRIPTION''OF'THE'PRIOR ART
!
Tile stoves, which are generally made by stove fitters,
consists of ceramic tiles with ribs arranged on their rear
sides and running parallel to their edges. Said ribs are
adapted to link the individual tiles to one another by
means of connecting clamps or the like, and the joints
between the tiles are closed by means of a refractory
material. The internal structure, the flue gas vents, are
also made by refractory blocks, which have to be processed
to get to the required shape. The construction of a tile
stove requires hard work, skill in the art as well as
great technical skill. In order to facilitate such work,
it has already been tried to construct the tile stove with
two shells. In such case, the internal shell and structure
~ ` 113873~i
are made of refractory blocks, and then the outer surface is
covered by tiles, either by individual tiles or by slabs consist-
ing of tiles. This work, too, should be done by a person skilled
in the art even in view of the fact that the work has been sub-
stantially facilitated because of the external shell of tiles.
SUMMARY OF THE INVENTION
It is, therefore, the object of this invention to pro-
vide blocks of the afore-mentioned kind for the construction of
a two-shell tile stove by means of which tile stoves of any
size can easily be constructed without requiring any particular
skill in the art. It is a particular object of the invention to
facilitate the assembly of the internal shell and structure, such
as flue gas vents etc.
According to the invention this is achieved by providing
a refractory block of brick for the construction of the internal
shell and i~ternal structure of a two-shell tile stove with an-
external shell of tiles, characterized in that said block or
brick has a longitudinal center rib in two faces being in con-
tact with adjacent blocks, further having a corresponding longi-
tudinal groove on the two other faces being in contact with ad-
jacent blocks and at least one first lateral groove arranged on
the first of the two side faces as well as at least one second
lateral groove intersecting said first lateral groove at a right
angle, one marglnal distance of one of said first and second
lateral grooves, each, corresponding to the marginal distance
of said longitudinal groove in said two other faces of said block,
and that the second of said two side faces is closed and planar~

Blocks having grooves and ribs on their faces being
in contact with adjacent blocks and on their side faces
have already been described in the AT-PS 314.165. The
blocks described therein have, however, grooves and ribs
on both side faces so that they are unsuitable for
the construction of the internal shell of a tile stove.
- In tile stoves, the side faces of the blocks directed
towards the tiles must be closed and planar in orde~ to
prevent the formation of air cushions between the adjacent
tiles and -the blocks, which cushions would impair the
heat conduction.
A firs-t embodiment provides that the side faces are
provided with at leas-t two first parallel lateral grooves,
the center distance of said grooves corresponding to the
wall thickness of the block.
A particularly great number of positions of the.blocks
in respect of one another will be obtained by providing
the side face wlth a-t least one second latera:L groove
being to the longitudinal yroove, said second lateral
groove intersecting the first lateral groove or grooves
at a right angle, the marginal distance of said second
lateral groove corresponding to the marginal distance of
the londitudinal groove. This embodiment, too, preferably
-" :` 113~736

provides that at least two second parallel lateral grooves
are arranged on the side face, the center distance of
said second lateral grooves corresponding to the wall
thickness of the block.
The block or brick according to the invention comprises,
as already mentioned, a closed planar side face which
is directed towards the tiles. Hence, the internal shell
has a plane external face on which the tiles fit snuggly,
and the formation of air cushlons and air channels is
eliminated. In spite of the fact that grooves are only
provided on three sides, an easy construction of the
internal structure is ensured, the longitudinal ribs of
horizontally arranged blocks being adapted to engage
.~ .
the lateral grooves of the blocks of the internal shell.
A thin layer of adhesive mortar is preferably employed
for connecting the blocks. The blocks can be prefabricated
to form a construction kit and can easily be built
! together without any skill in the art by means of en-
closed instructions or plans. The correct cross-sections
of flue gas vents need not be determined, no particular
attention is required, when bricking up the blocks etc.,
as the blocks have been put together correctly, when one
¦ rib provided on the block face engages one longitudinal
¦ groove or lateral groove.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
.
The blocks 1 according to the invention preferably have
square side faces 14,15, one side face 15 being closed and plan-
ar. When constructing the internal shell of a tile stove, the
blocks 1 are staggered in such a manner that the closed planar
side faces 15 form the external side of the internal shell so that
the tiles 4 fit snuggly on the blocks 1 without forming air
cushions or air channels. The tiles 4 obviously have planar
closed rear faces without ribs. For linking the tiles 4 to one
another (Fig. 6), their faces 20 being in contact with adjacent
tiles are provided with circumferential grooves 18. T-shaped
connecting members 19 are inserted into the grooves of the tiles
4, the center leg of the T-shaped connecting member 19 ,c"onnecting
two adjacent
5 -
--~ 113~l736
tiles 4 and the cross bar of the connecting member 19 said two
adjacent tiles with a tile 4 of the following row.
Two faces 10 of the block 1 being in contact with adja-
cent blocks are provided with longitudinal center ribs 12, and
the two opposite faces 11 are provided with longitudinal grooves
13 corresponding to the longitudinal ribs 12. As illustrated in
Figures 1 and 2 as well as 5 and 6, the longitudinal ribs 12
and the longitudinal grooves 13 can be arranged on adjacent
faces of the block or, according to Figures 3 and 4, on opposite
faces of the block.
The construction of the tile stove is substantially
facilitated by first and second lateral grooves 16,17, which
are provided on the other side face 14 of the block 1 directed
towards the inside, when being bricked up.

Figures 1 and 2 show a preferred embodiment. Four
first lateral grooves 16 are provided' on the side'faces 14,
,said grooves 16 having the breadth'y being equal to the breadth
of the longitudinal groove 13, the'center distance z or two
first lateral grooves 16, each, being equal to the wall thickness
d and the marginal distance x being equal to the marginal distance
of the longitudinal groove 13. Moreover, four second lateral
grooves 17 are provided, which intersecting the first lateral
grooves 16 at a right angle and for which the same relations are
true. Elevations remain between the lateral grooves 16, 17, the
surfaces of said elevations having the size x mu].tiplied by x in
the corner region, the size x multiplied by 2 x in the
- 7 -

residual marginal portion and the size 2 x multiplied
by 2 x in the center portion.
Because of its great number of lateral grooves, this
block can be used for all intermediate plates, partition
walls ~or flue gas vents etc. required in the internal
structure of the tile stove, as, according to the
embodiment illustrated in Fig. 5, any arrangements can
be bricked up in a simple manner.
The brick illustrated in Figures 3 and 4 shows a further
variant with rectangular side faces 14, 15. Two first and
two second lateral side grooves 16, 17, each, are provided
on the side faces 14, said lateral grooves having the
marginal distances x corresponding to the marginal
distances of the longitudinal grooves 13 and longitudinal
r:ibs 12. This embodimen-t shows the possibility of providing
the longitud:Lnal ribs 12 and the longitudinal ~rooves 13
on two op"osi-te faces 3. This ~lock can obviously also De
provided with further lateral grooves.
By means of the blocks or bricks according to this in-
vention, the dimensions of the individual blocks required
for -two-shell -~:ile s-toves can he pre-calculated and
bought preferably together with the tiles 4 as a
construction kit. The internal shell and the internal
structure can be built according to instructions without
requiring any particular skill in the art as the length of
113t~736
the individual blocks is clearly defined by the grooves
and ribs, and,moreover, in case of several possibilities
said length can be easily pre-marked.
