PROVISIONAL SPECIFICATION.
Improvements in Insulating Bricks and the like..
We, SAMUEL POLLAK, of Klansenburg, in the Kingdom of Hungary, Cement
Manufacturer, and NORBERT ZWILINGER, of Egeres, in the Kingdom of Hungary,
Factory Manager, do hereby declare the nature of our said invention to be as
follows:-
This invention relates to a method of making insulating bricks for building
purposes, such bricks replacing the usual asphalt fabric, tarred roofing-folt, and
asphalt-sheets, and being also applicablo for whole buildings which are subject to
the action of water, acids and alkalics, or their respective vapours.
The method of making the bricks is as follows:-
Ordinary bricks, on being removed from the kiln and whilst in the hottest state
possible, are placed upon paternosters, travelling-chains or bands of known con-
struction, and thus passed through a heated receptacle made of iron or other
suitable material and containing hot tar, asphalt, paraffin, pitch, or a mixture or
solutions of samo. The length of time for passing the bricks through such bith
is dependent upon the porosity of the former; they are, however, kopt in the bath
until thoroughly impregnated.
This manner of imprognating is very advantageous, seeing that the bricks, which
pass directly from the kiln into the bath, aro uniformly hot all through, and
practically void of air; hence they are in the best possible stato for receiving the
impregnating medium. If the bricks were first allowed to cool, much time, labour
and expenso would have to be incurred in the re-heating of same, and, moreover,
such bricks would not receive the impregnating modium nearly so well.
use
Bricks impregnated in the manner above described are ready for
immediately they cool, and may be embedded in Portland, hydraulic, tar or
asphalt cement.
These insulating bricks offer the further great advantage over the tarred roofing-
felt and asphalt-fabric or plates in use, that walls built with same are not broken
at intervals as, for instanco, when asphalt plates are used, and hence a horizontal
displacement cannot possibly occur. Seeing that the bricks possess no capillary
action, their insulating property is equal in evory respect to that of the plates
previously used, while one layor of such bricks is at least five times higher
than such plates; walls formed with same are thus far safer and perfectly
insulated.
These bricks are particularly adapted for the walls of rooms or chambers subject
to the action of steam, acid or alkaline vapours, seeing that they are not .acted
upon by, and are impermeable to such vapours. Moreover, they are also well
adapted for decomposing, black-ash, or other furnaces used in the chemical industry.
It will also be evident that the bricks may be made of all shapes, and that they
may even be mado into insulators for electric conductors and cables; they may also
replace the porcelain insulators and tubes.
In consequence of the cheapness of production, the bricks may be used for an
unlimited number of purposes, especially as they form at the same time an effective
agent for destroying vermin, contagious germs and the like.

We, SAMUEL POLLAK of Klausenburg in the Kingdom of Hungary, Cement
Manufacturer, and NORBERT ZWILINGER of Egeres, in the Kingdom of Hungary,
Factory Manager, do hereby declare the nature of our said 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 a method of making insulating bricks for building purposes,
such bricks replacing the usual asphalt fabric, tarred roofing-felt and asphalt-sheets,
and being also applicable for whole buildings which are subject to the action of water,
acids and alkalies, or their respective vapours.
The method of making the bricks is as follows:-
Ordinary bricks on being removed from the kiln and whilst in the hottest state
possible, are placed upon paternostors, travelling-ohains or bands of known con-
struction, and thus passed through a heated receptacle made of iron or other suitable
material and containing hot tar, paraffin, pitch, or a mixture or solutions of same.
The length of time for passing the bricks through such bath is dependent upon
the porosity of the former; they are however, kept in the bath until thoroughly
impregnated.
This manner of impregnating is very advantageous, seeing that the bricks which
pass directly from the kiln into the bath are uniformly hot all through, and practically
void of air; hence they are in the best possible state for receiving the impregnating
medium. If the bricks were first allowed to cool, much time, labour and expense
would have to be incurred in the re-hoating of samo, and moreover, such bricks would
not receive the impregnating medium nearly so well.
Bricks impregnated in the manner above described are ready for use immediately
thoy cool, and quay be ombedded in Portland, hydraulic, tar, or asphalt cement.
These insulating bricks offer the further great advantage over the tarred roofing
felt and asphalt fabric or plates in use, that walls built with same are not broken
at intervals as, for instanco, when asphalt plates are used, and hence a horizontal
displacement cannot possibly occur. Seeing that the bricks possess no capillary
action, their insulating property is equal in every respect to that of the plates,
previously used, while one layer of such bricks is at least five times higher than
such plates; walls formed with same are thus far safer and perfectly insulated.
These bricks are particularly adapted for the walls of rooms or chambers subject
to the action of steam, acid or alkaline vapours, seeing that they are not acted
upon by and are impermeable to, such vapors.
Moreover, they are also well adapted for decomposing black-ash, or other furnaces
used in the chemical industry.
'
It will also be evident that the bricks may be made of all shapes, and that they may
oven be made into insulators for electric conductors and cables; they may also replace
the porcelain insulators and tubes.
In consequence of the cheapness of production, the bricks may be used for an
unlimited number of purposes especially as they form at the same time an effective
agent for destroying vermin, contagious germs and the like.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The method of making bricks or the like for insulating purposes, consisting
in laying such bricks direct from the kiln on to a paternoster or travelling band,

tar, paraffin or pitch, or a mixture of same, substantially as described.
2. The use of insulating bricks or tho like for building purposes, electric
insulators and for rendering floors and walls damp-proof, snoh bricks being made
by impregnating same immediately on leaving the kiln with a hot solution of
asphalt, tar, paraffin or pitch, or a mixture of saine, substantially as described.
