PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Production of Artificial Fuel.
I THOMAS WILLIAM JOHNSON of 32 Harrogate Street Sunderland in the
County of Durham Engineer do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in that type of machinery for the
manufacture of artificial fuel in which a trough is formed of 4 adjustable parts for
the filling, compressing, & discharging of the bricks or briquettes, which in this
invention, each receives the pressure 5 times previous to being discharged.
Heretofore bricks or briquettes have only received one compression previous to
being discharged and the moulds not adjustable, whereby the capacity of this
machine, is greatly increased and the bricks or briquettes are solid and hard.
The trough or mould for receiving the mixture for compression and discharging
is composed of the following adjustable parts.
A. is a slab or bottom.
B. B. are the sides.
C. is the ram.
D. is the cover.

COMPLETE SPECIFICATION.
Improvements in Machinery for the Production of Artificial Fuel.
I, THOMAS WILLIAM JOHNSON 34, Lichfield Road Bow London E. and
formerly of 32, Harrogate Street Sunderland in the County of Durham, Engineer,
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 improvements in that type of machinery for the
production of artificial fuel in which a trough is formed of four adjustable parts
for the filling compressing and discharging of fuel, by this invention each brick
receives the full pressure 5 times previous to being discharged.
Heretofore bricks have only received full pressure once previous to being
discharged. Now in this improved machine the mixture of coal & pitch or other
materials, while leaving the cooling pan is regulated by the slide G, & assisted by
the revolving breakers H to front of ram C, which is actuated by a connecting
rod & crank, driven by a spur wheel & pinion, as the ram recedes a sufficient
quantity of the mixture to make a block, falls in front of the ram, and as the ram
advances the mixture when sufficiently pressed against the nearest block, causes
all the others to advance, the block nearest the end of trough being pushed ont
on to a table not shewn, the lever F presses on the cover D which works on
gudgeon E. The trough is composed of the 4 following parts.

page_text: C. the cover.
The sides are so arranged that by replacing the ram & cover blocks of various
sizes can be made, hitherto moulds have been made in one piece & not adjustable.
The same letters of reference indicate corresponding parts in drawings left with
the Provisional Specification.
Having now particularly described & ascertained the nature of the said inven-
tion, and in what manner the same is performed, I declare that what I claim is
First. An adjustable trough or mould which can be adjusted to make blocks of
different sizes.
Second. The slide & breakers to regulate the supply of mixture to trough for
compression.
