PROVISIONAL SPECIFICATION.
Improved Means or Process for Producing Block Fuel.
I ALFRED NORREYS, of 14 Great Winchester Street, City of London, Stock
Broker, do hereby declare the nature of this invention to be as follows :-
This invention relates to Improved Means or Process for Producing Block Fuel
in which certain well known ingredients are employed and mixed in about given
quantities and manner and finally amalgamated and moulded without pressure.
For the purpose of my invention I use soap, dextrine, water, petroleum, (crude),
stearine or waste from stearine, peat or sawdust and rosin in or about the following
proportions.
Soap
Dextrine
Water
Petroleum (crude)
Stearine (or waste)
Peat or sawdust

I mash up the soap with 8 parts water and heat it to boiling point in a cauldron,
the petroleum is introduced gradually, then the stearine or stearine waste, next the
dextrine with the remainder of the water as a paste, then the peat and rosin in
powder, stirring going on all the time to thoroughly associate the ingredients.
The mass can be scooped or run into moulds to solidify.
The fuel so made produces no clinker, no pitchy residue, very little smoke, lights
easily, burns freely and leaves an ash.

same is to be performed to be particularly described and ascertained in and by
the following statement :—

For the purpose of my invention I use soap, water, petroleum (crude), stearine

I mash up the soap with 8 parts of water and heat it to boiling point in a
cauldron, the petroleum is introduced gradually, then the stearine or stearine waste 1
or earth wax waste with the remainder of the water as a paste, then the peat and
rosin in powder stirring going on all the time to thoroughly associate the
ingredients.
The mass can be scooped or run into moulds to solidify.
The fuel so made produces no clinker, no pitchy residue, very little smoke, lights 1
easily, burns freely and leaves an ash and not a hard caked substance as with most
block fuel.
In my Provisional Specification I refer to the use of dextrine but I find in
completing my experiments that such material does not play any important feature
in the manufacture of the fuel blocks.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The ingredients hereinbefore referred to, treated in the manner set forth for
the manufacture of block fuel.
2. The manufacture of block fuel from a combination of the ingredients named
in or about the proportions mentioned, and prepared or treated as described.
