Improvements in Machinery for Moulding Fuel into Blocks.
J, LINCOLN FURRELL of Hope Wharf Rotherhithe London S.E. Coal Merchant do
hereby declare the nature of this Invention to be as follows:-
This Invention has for its object improvements in machinery for moulding fuel into
blocks.
I employ for this purpose a disc having in its face eight or other number of recesses
which serve as moulds. This disc is mounted so that it can turn about a vertical stud
or axis.
Together with this disc two rams are employed; they are connected with a rocking
beam and at each descent of the beam one of the rams enters one of the recesses and
by exerting a pressure on the material which it contains moulds it into a block and
at the same time the other ram enters another recess on the other side of the disc
and ejects from it the block previously moulded.
The disc is caused to move round step by step between the descents of the ram.
This movement is obtained by means of a driving pawl engaging with ratchet teeth
formed on the periphery of the disc. The driving pawl is carried by a lever which
is moveable around the stud on which the disc is mounted. The lever carrying the
driving pawl is connected by a link with an arm upon an horizontal axis which is
also furnished with a second arm and the end of this second arm is held by a slotted
connecting rod jointed to the extremity of the beam. The material to form the
blocks is fed into a hopper and the disc is immediately beneath the lower end of the
hopper.
There is a plate beneath the disc at the point where the hopper is placed which
closes the lower ends of the moulding recesses as they pass beneath the hopper.
Similarly the moulding recesses are closed as they pass the moulding ram by the
plate which rests upon a suitable foundation.
The further end of the beam is connected by a connecting rod with a crank on an
horizontal axis which carries a fly wheel and is driven by suitable gearing. The
action of the machine is then as follows:-The moulding recesses in the disc pass in
turn beneath the hopper and so are filled with the material, then by the movement
which the ratchet and pawl imparts to the disc the charged recess is brought beneath
the moulding rain and the block is consolidated; then by the time the disc has
made a further half revolution the recess containing the moulded block reaches the
ejecting ram and finally when this ram descends the block is pushed out of the
recess whilst simultaneously another block is consolidated. The blocks are conveyed
away down an incline or in other convenient manner.

Improvements in Machinery for Moulding Fuel into Blocks.
I, LINCOLN FURRELL of Hope Wharf, Rotherhithe London, S.E. Coal Merchant
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 has for its object improvements in machinery for moulding fuel into

page_text: employ for this purpose a disc having in its face eight or other number of
recesses which serve as moulds. This disc is mounted so that it can turn about a
vertical stud or axis.
Together with this disc two rams are employed preferably each is provided with
several heads or plungers, they are connected with a rocking beam and at each
descent of the beam the plungers of the ram enter one set of recesses and by exerting
a pressure on the material which they contain moulds into blocks and at the same time
the plungers on the other ram enter another set of recesses on the other side of the
disc and ejects from them the blocks previously moulded.
The disc is caused to move round step by step between the descents of the rams.
This movement is obtained by means of a driving pawl engaging with ratchet teeth
formed on the periphery of the disc. The driving pawi is carried by a lever which is
moveable around the stud on which the disc is mounted. The lever carrying the
driving pawl is connected by a link with an arm upon a horizontal axis which is also
furnished with a second arm and the end of this second arm is held by a slotted
connecting rod jointed to the beam. The material to form the blocks is fed into a
hopper and the disc is immediately beneath the lower end of the hopper.
There is a plate beneath the disc at the point where the hopper is placed which
closes the lower ends of the moulding recesses as they pass beneath the hopper.
Similarly the moulding recesses are closed as they pass the moulding ram by the
plate which rests upon a suitable foundation.
The further end of the beam is connected by a connecting rod with a crank on
a horizontal axis which carries a fly wheel and is driven by suitable gearing. The
action of the machine is then as follows:-The moulding recesses in the disc pass
in turn beneath the hopper and so are filled with the material, then by the movement
which the ratchet and pawl imparts to the disc the charged recesses are brought
beneath the moulding ram and the blocks are consolidated then by the time the
disc has made a further half revolution the recesses containing the moulded blocks
reach the ejecting plungers and finally when this ram descends the blocks are pushed
out of the recesses whilst simultaneously other blocks are consolidated. The blocks
are conveyed away down an incline or in other convenient manner.
Preferably the apparatus is duplicated consolidating and ejecting rams being placed
on each arm of the beam.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation partly in section of a machine constructed according to
my Invention.
Figure 2 is an end elevation, and
Figure 3 a plan.
In this machine there are four plungers on each ram and a set of rams is placed
on each arm of the beam.
A is the beam which is caused to oscillate by means of the connecting rod B and
crank shaft C which carries the wheel C gearing with the pinion D₁ on the same
axis as the pulley D driven by a band. Pivotted to the beam are four rams E E,
and F F, each of which carry four plungers E₁ and F. These plungers enter the
recesses in the rotating moulds G G. The rams E E, which have the least travel are
the compressing rams by which the material is compressed into blocks, whilst the
rams F, F, which have a longer travel are the expelling rams.
The rotating
moulds G G, are mounted upon plates H which are cut away beneath the expelling
rams to allow the blocks to be forced out of the moulds. The moulds G are pivotted upon
vertical axes J J. K, K, are levers also pivotted to the axes J, J, their outer ends
carry pawls L L, which take into notches on the peripheries of the moulds G. M. is
a rod one end of which is pivotted to the lever K whilst the other end is pivotted to
the arm N on the spindle N. The other arm N of the spindle N carries a pin
which works in the slot O' of the connecting rod O whose upper end is pivotted to the
beam A. P is the hopper which is provided with two mouths or spouts Q, Q,

page_text: one for each set of moulds. The stirrers R R in the hoppers are driven by the
band S from the main axis.
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 combination of a rocking beam carrying compressing and expelling rams
each of which has one or more plungers and a rotating mould substantially as
described.
2. The combination of a rocking beam, a rotating mould and connections between
the beam and the mould by which a step by step motion of rotation is given to the
latter substantially as described.
3. The combination of the rocking beam A, the connecting rod O the lever N, the
rod M the lever K the pawl L and mould G substantially as described.
4. Machinery for moulding fuel into blocks substantially as described.
