PROVISIONAL SPECIFICATION,
Improvements in the Manufacture of Fire-lighters or Artificial Fuel
from Wood, Sawdust, Turf, Peat, or similar Materials, applicable
for Stoves, Hearths, Fireplaces, or the like.
I, HILDING WILHELM REGNANDER, C.E., of Skönvik, in the Kingdom of Sweden.
do hereby declare the nature of this invention to be as follows:-
The present invention relates to a process for the production of fire lighters or
artificial fuel for earthenware stoves, chimneys, hearths and other fire places, from
wood, sawdust, turf, peat and other material.
In carrying out the invention one or several of the above mentioned materials
are mixed with a proper quantity of resinous matters and the compound pressed.
into briquettes or other shape, the kindling of which may be facilitated by steep-
ing them in a resinous liquid or in a solution of resinous substances in oil (for
instance tar oil) and subsequently drying them. The briquettes may be made of
such a shape that they present the greatest possible surface to the access of air
during combustion, say, by means of perforation, making a hole in the centre,
grooving them, or by two or more of these methods combined..
The briquettes are made as follows. The raw material, which must be dry, is
pulverized (in case the pieces should not be already sufficiently small) and is
mixed with 10 to 30 per cent. in weight or resin or resinous substances. The
material thus produced is passed into a briquette press which is constructed with
suitable dies to give the briquettes the greatest possible extent of surface. When
the briquettes are made they are steeeped in molten resin or in a concentrated
solution of resinous substances in oil (say tar oil) and are dried in the usual way;
they are then ready for use.
The firelighters produced in the way above described are very effective and
comparatively cheap.

ing statement:-
The invention relates to a process for the production of fire lighters or artificial
fuel for earthenware stoves, chimneys, hearths and other fire-places, from wood,
sawdust, turf peat and other material.
In carrying out the invention one or several of the above mentioned materials
are mixed with a proper quantity of pulverized resin and the compound pressed
into briquettes or other shape, the kindling of which may be facilitated by steep-
ing them in a solution of resin in oil (for instance tar oil) and subsequently drying
them. The briquettes may be made of such a shape that they present the greatest
possible surface to the access of air during combustion, say, by means of perforation
making a hole in the centre, grooving them, or by two or more of these methods
combined.
The briquettes are made as follows. The raw material, which must be dry, is
pulverized (in case the pieces should not be already sufficiently small) and is
mixed with 10 to 30 per centum in weight of pulverized resin. The material thus
produced is passed into a briquette press which is constructed with suitable dies to
give the briquettes the greatest possible extent of surface. When the briquettes
are made they are steeped in a concentrated solution of resinous substances in oil
(say tar oil) and are dried in the usual way; they are then ready for use.
The firelighters produced in the way above described are very effective and
comparatively cheap.
Having now particularly described 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. A process for the production of fire-lighters or fuel from wood sawdust, turf,
peat and similar substances for tiled stoves, chimneys, hearths and other fire places
in which process the above mentioned substances are mixed with 10 to 30 per
centum by weight of pulverized resin and the resulting compound compressed into
briquettes of a suitable shape and dipped in a resinous solution in oil (for instance
tar oil) to cover them with a coating which facilitates their being kindled sub-
stantially as described.
2. Firelighters produced according to the process substantially as described.
