WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the year
of our Lord' One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Box, Her special licence that I,
-the said John Box, my executors, administrators, and assigns,' or 'such
others as I, the said John Box, my executors, administrators, and
assigns, should at any time agree with and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "A NEW OR IMPROVED MACHINE
FOR COMPRESSING DUST COAL," a communication to him from abroad by
Severin Surowiéz, of 47, Rue d'Angouléme, in the "City of Paris, upon
the condition (amongst others) that I, the said John Box, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals,

page_text: the following statement :—-
The machine consists of a solid framework of cast iron, upon which
rest all the accessories to the machine.
L
The machine is moved by steam or other motive power; it principally*
consists of a drum.or roller moved by a strap or driving band cogged at
the edge, hollowed in the centre. This drum or roller is pierced with
twenty-eight or more or less.orifices, in which are inserted twenty-eight
or more pistons which are hollowed out at one end-in-a-hemisphere.
In case the compressed fuel is to be of a spherical form or the one half 1
of any other form which may be considered: desirable, the other end of
each of the pistons is furnished with a small solid wheel or roller. The
pistons turn with the drum, but they have also an horizontal movement
which is caused by the rolling of the small wheels on two inclined
planes fixed to the frame of the machine. These pistons are placed, in
pairs facing one another, so that when brought, together by the circular
movement of the drum and the horizontal movement caused by the
rolling of the small wheels on the inclined planes form a mould, of the
desired form. Within the larger pistons or moulds are smaller pistons.
held in place by a spiral spring; when the hollow, pistons .or, moulds
separate the smaller pistons push the compressed coal from the mould.,
in which it may have remained attached.

The machine is fed or supplied by an ordinary elevator with buckets
or scoops which lifts the dust coal from a receptacle conveniently placed
to receive the dust after it is prepared in a cylindrical pug mill, through
which passes a shaft furnished with arms which mix the coal tar
or other adhesive or glutinous matter. The mixture is heated, by a
steam jet:

When the elevator has lifted the dust to the top of the machine.it
falls into a hopper which is regulated by a slide moved by an endless
chain, which takes its movement from the shaft or axis on which the
drums turn.

page_text: DESCRIPTION OF THE DRAWING!
Fig. 1 represents a side elevation; Fig. 2 represents a front elevation
of my new or improved coal dust compressing machine; Figs. 3, 4,
and 5 are detailed Drawings of the moulds or pressing pistons.
i
In Figs. 1 and 2 A is the framework of the machine; "B is the
hopper into which the previously prepared coal dust and pitch or other
material is continuously being fed; C is a crammer or feeder, which by
revolving upon its axis C forces the material into the chambers or
spaces D. in the drum E, in front of the moulds or pressing
pistons F, F; E is the drum or mould wheel mounted and free to turn
upon the axis E. The drum has a number of holes pierced in pairs
near to its periphery and parallel to its axis E¹. These holes are each
fitted with a piston or half mould F. These pistons F, F, travel round.
with the drum E, but they have another, and independent motion parallel.
with the axis E' of the drum E. One of these pistons F is shewn in
detail in Figs. 3, 4, and 5; one end K. forming the mould is shaped to a
hemispherical or other desired hollow form, and the other end is fitted
with a solid friction wheel L, and also a smaller friction wheel M. There
is also a small piston N contained within the larger one F; this small
piston is held in its place by the spiral spring O; it is shaped at one end
so as form a part of the hemispherical or other shaped cup or mould K.
It can only be moved forward by exerting a pressure upon the
small wheel P attached to the lever R moving upon the centre S.
G, G, Figs. 1 and 2, are inclined planes fixed to the framework A of the
machine upon which the large friction wheels L run; H, H, are other
inclined planes upon which the small friction wheels M run; J is a
regulating sluice for regulating the quantity of material in the moulds
at each charge. The drum or mould wheel E and also the crammer or
feeder C being caused to revolve by means of suitable gearing, the
pistons or moulds are alternately brought under the hopper B, and the
pistons or half moulds being (at that part of the revolution) open or
withdrawn, the material is fed into the chambers or spaces D in front of
each pair of pistons, and as the drum E continues to revolve the
charged chambers D past under and past the regulator J. The friction
wheels L, L, run up the inclines G, G, and each pair of pistons are
caused successively to close and compress or agglomerate the material
between them; so soon as the compression is complete the friction

wheels L, L, leave the inclines G, G, and the small wheels M, M,
run under the inclines H, H, and cause the large pistons or moulds
to begin to open; but as the small wheels P, P, on the end of the
levers. R, R, do not leave the inclines G, G, until a little later than
the large wheels L, L, the small pistons N are held forward for an a
instant and thus releases the balls or lump from the cups; immediately
the small wheels N leave the inclines G, G, the small pistons are returned
'to their places by the action of the springs O. The agglomerate, then
falls out and if made in a spherical form may be conducted by inclines
_ to any desired receptacle..
In witness whereof, I, the said John Box, have hereunto set my
hand and seal, this Thirteenth day of June, in the year of
our Lord One thousand eight hundred and seventy-two.
