Improvements relating to the Preparation of Tar, Chiefly Designed
for Use in the Manufacture of Artificial Fuel.
1, HENRY HARRIS LAKE, ot, the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:―
This invention relates to the preparation of an improved tar by the combination
either of tar from coal-tar distilleries with tar from blast-furnaces; or of these two
tars mixed together, with the addition of heavy oils of creosote or coal-tar; or of tar
from blast-furnaces mixed with heavy oils of creosote or coal-tar.
The improved process of preparing this tar is as follows
-
The tar from blast furnaces is not sufficiently cohesive for agglomerating coal owing
to the absence of suitable elements as is shown by the pulverulent and swollen nature
of their coke. It will be understood that if with this coke are mixed the above-
mentioned tars an improved tar having special properties will be obtained which can
under certain conditions be advantageously used for the manufacture of blocks of
artificial fuel.
The said process therefore enables the preparation of tar which has not heretofore
been known by the employment of the above mentioned tars which are mixed in any
desired proportion, and then cast together at a suitable temperature without burning
them, with or without an addition of coal-tar or creosote-oils if greater adhesive
qualities are to be given to the tar.
It has not heretofore been known that tar from blast-furnaces has been mixed and
cast together with the tar from distilleries in order to prepare tar suitable for the
manufacture of blocks of artificial fuel; nor that creosote oils have ever been added to
tar from blast-furnaces like the tar from distilleries.
From this it will be obvious that my process of preparing tar as above described
constitutes an invention which will be found exceptionally advantageous in its applica-
tion to industrial purposes.

Improvements relating to the Preparation of Tar, Chiefly Designed
for Use in the Manufacture of Artificial Fuel.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 the preparation of an improved tar by the combination
either of tar from coal-tar distilleries with tar from blast-furnaces; or of these two
tars mixed together, with the addition of heavy oils of creosote or coal-tar, or of tar
from blast-furnaces mixed with heavy oils of creosote or coal-tar.
According to the aforesaid invention the improved tar is prepared with the aid of
one or the other of the above mentioned tars mixed at will in any suitable proportion
and melted together, when thus 'mixed, at a proper temperature so as not to burn
them, heavy oils of creosote or coal-tar being added if a greater adhesive power is to.
be imparted to the tar.

page_text: tion of the coal, owing to the absence of binding elements as shown by the pulveru
Turnaces is not sufficiently cohesive for the
and swollen nature of their coke. It will be understood that if to this coke is impa
proper agglom
some of the aforesaid binding elements a tar having special properties is obtai
which in certain cases and according to the qualities which are given to it can
advantageously used for the manufacture of blocks of artificial fuel.
The mixing and melting of the materials above named can be effected in any ki
of boiler or vessel, so that it will not be necessary to give a special description of
same; any vessel or boiler having a fire-place, provided that it be sufficiently larg
can be employed for carrying out the operation.
Having put the materials which I desire to melt into the boiler or vessel
disposal, I preferably proceed as follows:-
:-
First. As regards the first case, supposing that I operate upon 10,000 kilogramm
of tar, I put in the boiler
7500 kilogrammes of tar from distilleries and 2500 kilogrammes of tar from blas
furnaces.
I cause the whole to melt by means of a moderate fire; when the whole has bee
well melted I cover the fire in the fire-place in order to prevent the melted materia
being burnt; if the boiler or vessel is provided with a stirrer, I actuate the latter fo
intimately mixing the melted materials, and in the absence of a stirrer, I prepar
this mixture by hand through the medium of bent shovel or any similar tool. I ther
allow the melted tar thus mixed to flow into a pit provided for this purpose, where i
is allowed to cool, and the operation is terminated.
Second. As regards the second case, making use of the same means as above-
described, I chargo the boiler or the vessel with
7000 kilogrammes of tar from distilleries, 2500 kilogrammes of tar from blast-
furnaces, and 500 kilogrammes of heavy oils of creosote or coal-tar.
The whole is caused to melt and is mixed as in the first case, but at a somewhat
higher temperature ;
Third. As regards the third case, also making use of the same means as above
then allow it to flow out, and the operation is terminated.
described, I charge the boiler with
of creosote or coal-tar.
9500 kilogrammes of tar from blast-furnaces, and 500 kilogrammes of heavy oils
the operation is then terminated.
I cause it to melt and flow out as in the first two cases and
The above examples of the method of operation being given only for the purpose
of enabling the means by which the improved process can be carried out, to be better
understood, I wish it understood that my invention does not consist in the application
of the apparatus used, which may be changed or modified at will; but that my said
invention consists solely in the mixing and fusion of the materials as. hereinbefore
described, for making an improved tar which will be found exceptionally advantageous
in its application to the agglomeration of the coal in the manufacture of artificial fuel.
Tar from blast furnaces has not heretofore been mixed and melted together with
tar from distilleries for treating the tar of gas-works or coke-furnaces, in order to
make a tar adapted for the manufacture of blocks of artificial fuel.
Moreover heavy oils of creosote have never (like tar from distilleries for enriching 4
the same) been added to tar from blast-furnaces by the producers nor have these tars
been given the carbon which they require to adapt them for the agglomeration of the
coal.
From the above it will be seen that the improved process of manufacturing a tar by
the above described means constitutes a valuable invention.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed as communicated to
by my foreign correspondent, 1 wish it understood that I claim :-
me
First. The mixing during fusion of tar from coal-tar distilleries, that is to say, tar
btained from gas-works or coke-furnaces with tar obtained from blast-furnaces the 55
ame being effected at any suitable temperature and in any suitable proportion.

page_text: Second. The mixing during fusion of the above-mentioned tars together with the
addition of coal-tar or heavy oils, that is to say, with heavy oils of creosote or with
one or the other of the materials contained in the heavy oils of creosote the same
being effected at any suitable temperature and in any suitable proportion.
Third. The mixing, during fusion of tar from blast furnaces mixed with coal-tar or
heavy oils of creosote that is to say with heavy oils of creosote or with one or the
other of the materials contained in the heavy oils of creosote, the same being effected
at any suitable temperature and in any suitable proportion.
