Middlesex, for an Invention of IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF AGGLOMERATED OR ARTIFICIAL FUEL
PROVISIONAL SPECIFICATION left by the said Elizabeth Marriott at the
Office of the Commissioners of Patents on the 8th October 1883.

MENTS IN APPARATUS FOR THE MANUFACTURE OF AGGLOMERATED OR ARTIFICIAL
FUEL

My Invention relates to apparatus for the manufacture of perforated blocks or
bricks of patent fuel composed of coal dust slack, and similar waste material
agglomerated by admixture with bituminous and other substances in suitable
proportions. The agglomerated materials are formed into bricks or blocks by
compression in moulds of suitable shape and dimensions, and the invention has for
its object to provide a machine of simple construction whereby the moulding and
perforating of the blocks or bricks may be expeditiously performed at one and the
same operation. The machine consists essentially of a mould of suitable form and
dimensions provided with a false bottom or follower operated by a cam or other
mechanical contrivance for raising the compressed block out of the mould, a plunger
corresponding to the area of the mould and capable of receiving reciprocating
motion for the purpose of compressing the agglomerated material therein, and a
series of core pins suitably arranged for forming the perforations in the desired
number and position in the block or brick of fuel said pins passing through
corresponding apertures in the plunger and being carried by a sliding head capable
of receiving reciprocating motion independently of the compressing plunger. To
ensure the through perforation of the compressed block of fuel the points of these
pins may be received in corresponding sockets in the bottom or follower of the
mould.
The parts will be so arranged and operated that the material may be readily
filled into the mould compressed therein around the pins by the plunger, the
pins withdrawn, the plunger removed and the compressed and perforated block
raised out of the mould. Or instead of the core pins passing downwards through
the plunger they might be attached to a fixed bottom of the mould and rise
through holes in the false bottom in which case the block would be removed from
the mould and raised off the core pins at the same time.

My Invention relates to apparatus for the manufacture of perforated blocks or
bricks of patent fuel composed of coal dust slack and similar waste material
agglomerated by admixture with bituminous and other substances in suitable
proportion. The agglomerated materials are formed into bricks or blocks by
compression in moulds of suitable shape and dimensions and the invention has for
its object to provide a machine of simple construction whereby the moulding and
perforating of the blocks or bricks may be expeditiously performed at one and the
same operation. The moulding part of the machine consists essentially of a
mould of suitable form and dimensions provided with a false bottom or follower
corresponding to the area of the mould and operated by a cam or other mechanical
contrivance for compressing the agglomerated material and raising the compressed
block out of the mould and a series of core pins suitably arranged for forming the
perforations in the desired number and position in the block or brick of fuel said
pins rising through corresponding holes in the false bottom or follower; the block
being removed from the mou'd and raised off the core pins at the same time.
In order that the invention may be more readily understood I have illustrated it
in the accompanying drawings and will proceed to describe it with reference
thereto.
Figure 1 is a part sectional elevation of the machine. Figure 2 is a vertical
section at right angles to figure 1 taken across the revolving mould table.
Figure 3 is a plan partly in section of the moulding apparatus and Figure 4 is a
plan of one of the moulds.
The agglomerated materials are placed in the pug mill A whereby they are
thoroughly mixed and are delivered through an apertare below into the mould
filling apparatus B whence it is delivered by rotating scrapers 5 into two adjacent
moulds c of the mould table C where it is compressed in the form of a perforated
block. A single main shaft D which derives its motion from the prime mover
actuates the three principal parts of the apparatus by means of suitable driving
wheels and pinions as will be clearly seen in the drawing and the rotating scrapers
are driven by a vertical shaft E actuated by the driving wheel F on the pug mill
shaft through the intervention of an intermediate wheel which gears into a toothed
wheel on the lower end of the shaft E. The moulds of the moulding or com-
pressing apparatus are arranged to come twice under the arms 6 of the scraper so
that the filling operation may be more completely effected than if the moulds were
filled at one operation.
The rotating mould table C is supported by a series of antifriction rollers G and
receives an intermittent motion from a crank H through a rod (figure 3) the
outer end of which takes into teth i on the periphery of the mould table. The
material in the moulds is subjected to pressure by the action of steam on the piston
in the steam cylinder K Figures 1 and 2 the lower end of the piston rod being
jointed to one end of the horizontal vibrating arın or lever L which has its fulcrum
at figure 2 and whenever the piston rises in the steam cylinder, the lever L forces
up one of the followers M m of the mould table and by this means a perfect
compression of the blocks is insured.
The compressing lever is provided with a thrust piece N jointed to it by a
knuckle and which bears against the bottom part of the mould follower. The
piston rod whereby the lever L is worked is accurately guided in a vertical

page_text: direction at its lower end. o are the core pins fixed in a plate O fixed in the
moul. These core pins rise up to the level of top face of the table and their
upper ends are tapered for a distance equal to the thickness of the compressed
block.
In the example shown the mould is divided into four by a cross piece O+ in one
with O for the purpose of moulding four blocks at once each with a central hole.
There is consequently one core pin in each cavity of the mould.
The follower is also divided into four perforated plates or false bottoms m fitting
the cavities of the mould and having holes fitting on the cylindrical portion of the
core pins and supported by distance posts m¹ rising from the lower part M of the
follower and passing freely through the plate O these posts screwing into the plate,
at top and into the lower part M. The compression of the materials in the mould
is effected by the follower being raised by the lever L at the moment when the
mould is under an abutment P.
By the rotary motion of the mould table C the moulds pass from under the
abutment and the lower parts M of the follower slide upon an incline Q whereby
the blocks are raised entirely out of the moulds by the time they arrive opposite a
vibrating lever R which is actuated by a cam r on a shaft mounted above the
steam cylinder, and whereby the compressed block is swept off on to an endless
band S.
Having described the nature of the said Invention and the manner of performing
the same I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is :
The herein described moulding apparatus consisting in the combination of the
follower M, the false bottoms m fixed to the follower and perforated to correspond
to the core pins, the stationary plate O and cross piece O, and the tapered core
pins o fixed to said plate and rising level with the top face of the mould table, the
whole fitted in each of the moulds of a rotary mould table for operation in
connection with the stationary abutment P, substantially as herein shown and
described for the purpose specified.
In witness whereof I the said Elizabeth Marriott have hereunto set my hand
and seal this nineteenth day of March A.D. 1884.
