PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Fuel Blocks.
I, WILLIAM BAKER HARTRIDGE, of 28, Victoria Street, Westminster, in the
County of London, Director of Public Company, do hereby declare the nature
of this invention to be as follows:
--
In my Specification No. 12389 of 1893 I have described fuel blocks each con-
sisting of a shell of carbonaceous material filled with coal and the like and in my
Specification No. 24796 of 1896, I have described a manufacture of such blocks
consisting of lengths of tube filled with coal or the like and closed at the ends
with suitable plugs.
My present invention relates to improvements in the manufacture of such blocks
whereby they can be produced more rapidly and economically.
For this purpose, I make a paste of carbonaceous and agglutinant material
as set forth in my previous Specification No. 12389 of 1893, and I form this paste
into tubes of circular rectangular or other section of suitable lengths as described
in my Specification No. 24796 of 1896
Instead of filling these tubes with coal dust or other combustible material as
described in my previous Specifications and then closing their ends with suitable
plugs, I, according to my present invention, form such coal dust or other suitable
material into columns or rods of section the same as that of the interior of the
tubes above referred to. These columns or rods are then forced into the tubes as
cores or the tubes are forced over these cores, so that the core occupies the whole
length of the tube. When fuel blocks of this kind are burnt the ends of the cores
being exposed to the fire become coked forming as it were plugs, preventing the
too rapid escape of the gas evolved from the inner part of the core.
cases I dispense with the inner core of combustible material, in which case I
prefer to make the tube of richer combustible materials and to make perforations
or cut holes through the sides of the tube at suitable distances apart so as to
facilitate the better combustion of same.

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
In my Specification No. 12389 of 1893 I have described fuel blocks each con-
sisting of a shell of carbonaceous material filled with coal and the like and in my
Specification No. 24796 of 1896, I have described a manufacture of such blocks
consisting of lengths of tube filled with coal or the like and closed at the ends
with suitable plugs.
My present invention relates to improvements in the manufacture of such blocks
whereby they can be produced more rapidly and economically.
For this purpose, I make a paste of carbonaceous and agglutinant material
as set forth in my previous Specification No. 12389 of 1893, and I form this paste
into tubes of circular rectangular or other section of suitable lengths as described
in my Specification No. 24796 of 1896.
Instead of filling these tubes with coal dust or other combustible material as
described in my previous Specifications and then closing their ends with suitable
plugs, I, according to my present invention, form such coal dust or other suitable
material into columns or rods of section the same as that of the interior of the
tubes above referred to. These columns or rods are then forced into the tubes as
cores or the tubes are forced over these cores, so that the core occupies the whole
length of the tube. When fuel blocks of this kind are burnt the ends of the cores
being exposed to the fire become coked forming as it were plugs, preventing the
too rapid escape of the gas evolved from the inner part of the core. In some
'cases I dispense with the inner core of combustible material, in which case I
prefer to make the tube of richer combustible materials and to make perforations
or cut holes through the sides of the tube at suitable distances apart so as to
facilitate its combustion.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
The herein described manufacture of fuel blocks each consisting of a tubular
shell of agglutinated combustible material filled with a core of agglutinated coal
dust or the like.
