Improvements in Thermo-electrical Building Bricks or Blocks,
I, JOSEPH MATTHIAS, of 56, Gymnasiums-strasse, Stuttgart, in the German
Empire, Telegraph Secretary, 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 building-bricks oi blocks such as ordinary bucks, arch-
stones, flag-stones and the like for the thermo-electrical utilization of waste heat,
having hollow spaces which are not completely filled with the thermo-elements.
which spaces form, when the blocks are laid in position, continuous passages for
the cooling aur, and which passages may be closed when requned In the
accompanying drawing is shown one method of carrying this invention into effect
Figure 1 is a vertical section, Figure 2 an underside view, Figure 3 a section
taken on line y of Figure 1 Figure 4a plan view and Figure 5 & perspective
view of a building buck or block The brick on bloch a 18 made of a suitable fire-
proof material, cement, or the like, and is provided with a recess e in which a
suitable number of theimo-electrical elements is so inserted that the end surfaces
g of the electrodes completely close the recess e on one side For this
pui pose the end surfaces of the electiode on this side are of square or rectangular
sertion,
The electrodes f f of an element are so shaped that a projection h on one elec-
tiode f takes into the other electiode Each element is separated from its
neighbour by an insulating laver of mica or the like These insulating layers
may consist of the same material as the stone itself and may be so arranged that
the side d is formed with cells in which the electrodes can be placed Of course
besides these layers of the same material as the stoue itself, other laveis of mica
or the like may be employed at the same time
At their other ends the electiodes terminate in a number of points ¹³ m
such a manner that the points of every two adjacent electrodes of opposite polarity
are connected together by a netal conductor m The conductor of the diagonally
opposite electrodes E E is led through holes in the wall of the buck oi block
and serves as a means of connection with the corresponding electrodes of the
neighbouring buck or block These building bricks oi blocks can be emploved
in all places where then surfaces will be radiated by heat, and vertical, horizontal,
or inclined, structures can be built up or lined therewith in exactly the same
manner as bricks, stones, arch-pieces, flags and so forth of the usual kind are
ordinarily employed but are so placed that the surfaces from which the ends of
the electrodes project are next the warm space The bricks on blocks are also
so arranged that the beforementioned hollow spaces form continuous passages or
channels through which is drawn by means of a ventilator, for example, a current
of cold an which cools the points of the inner ends of the electiodes
Thus the wall of a house exposed to the mid-day sun can be lined or covered
in this manner, and by means of the aforesaid cooling electrical energy can be
obtained For the same purpose in work-rooms in which during the evening or

page_text: might a number of gas flames burn, or in cases where heat-radiating machines
are used the whole ceiling may be lined with bucks on blocks of this kind
Having now particularly descubed and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1
Fust Building bucks or blocks provided with thermo-elements for the thermo-
electrical utilization of waste heat, the feature of which is that the hollow space
open at three side, and not completely filled up by the thermo-elements is com-
pletely closed by the ends of the electrodes and the insulating material between
them on the side which is turned towards the source of heat but ou the other sides
18 only partly closed whereby when the sand bucks or blocks are placed together
a continuous channel is produced for the air effecting the cooling of the pointed
ends of the electrodes in the inside of the buck or block substantially as described
Second Building bucks on blocks of the kind forming the subject of the first
claiming clause hereof in which the insulating material between the electrodes
consists of the material of the buck on block itself, and can be formed in the
moulding of the same, in which case still other insulating layers may be used at
the same time, substantially as described
