PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Fire Lighters.
We, WILLIAM DAVID ASHTON BOST and THOMAS FREDERICK HALDANE
Managing Directors of the Cartvale Chemical Company Limited, 59 New Sneddon
Street, Paisley, in the County of Renfrew, North Britain, do hereby declare the
nature of this invention to be as follows, that is to say :—
Our said invention has for its object the manufacture of fire lighters of improved
and superior kinds, in a simple and economical manner.
In carrying out our invention according to one modification we mix wood
charcoal in small pieces or roughly granulated with tar and with rosin in apparatus
of any suitable known kind; and thereby form a plastic mass which we mould into
any forms suitable for fire lighters. The moulded blocks are then dipped into
melted rosin which seals or coats their surfaces; and whilst the coating rosin is
still soft we place them in sawdust or other suitable powdered carbonaceous
materials which adhereing to their surfaces prevents the blocks from sticking
together and allows of their being handled without inconvenience. The sawdust
also facilitates the ignition of the blocks, and prevents the rosin from running.
The proportions of the ingredients may be varied but we obtain satisfactory
results by mixing two parts by weight of charcoal with one part of tar and one part
of rosin, whilst about one part of rosin is added in the dipping operation. The
mixing and moulding is facilitated by the addition of a little inexpensive oil or
fatty matter.
For the wood charcoal, or more or less of it, common coke or other suitable
carbonised vegetable matter may be substituted; and for the tar or a part thereof
there may be substituted any suitable tarry or bituminous matter capable of
forming an adherent mouldable mass with the other ingredients.
Dated this Eighteenth day of June 1892.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Fire Lighters.
We, WILLIAM DAVID ASHTON BOST and THOMAS FREDERICK HALDANE,
Managing Directors of the Cartvale Chemical Company, Limited, of 59, New
Sneddon Street, Paisley, in the County of Renfrew, North Britain, 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, that is to say :-
Our said invention has for its object the manufacture of fire lighters of improved
and superior kinds, in a simple and economical manner.
In carrying out our invention according to one modification, we mix wood
charcoal in small pieces, or roughly granulated, with tar and with rosin, in
apparatus of any suitable known kind; and thereby form a plastic or mouldable
mass which we mould into any forms suitable for fire lighters. The moulded
blocks are then dipped into melted rosin, which seals or coats their surfaces; and
whilst the coating rosin is still soft, we place them in sawdust or other suitable
powdered carbonaceous material, which adhering to their surfaces prevents the
blocks from sticking together, and allows of their being handled without incon-
venience. The sawdust also facilitates the ignition of the blocks, and prevents the
rosin from running.

page_text: The proportions of the ingredients may be varied, but we obtain satisfactory
results by mixing two parts by weight of charcoal with one part of tar and one part
of rosin, whilst about one part of rosin is added in the dipping operation. In some
cases as for example when less tar is used or when the tar is of low fluidity, the
mixing and moulding is facilitated by the addition of a little inexpensive oil or
fatty matter.
For the wood charcoal, or for more or less of it, common coke, or other suitable
more or less carbonised vegetable matter may be substituted; and for the tar or
for a part thereof there may be substituted any suitable tarry or bituminous matter
capable of forming an adherent mouldable mass with other ingredients.
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. Making fire lighters of the materials and in the manner substantially as
herein before described.
2. The coating or sealing of fire lighter blocks made of any suitable materials
with melted rosin, and causing sawdust or other suitable powdered carbonaceous
material to adhere to the coating substantially as and for the purposes herein before
described.
Dated this Sixteenth day of March 1893.
