Wood, at the Office of the Commissioners of Patents with their Petition,

We, WILLIAM WOOD and JAMES WILLIAM WOOD, of Monkhill, near Pon-
tefract, in the County of York, do hereby declare the nature of the said In-.
vention for "IMPROVEMENTS IN THE MANUFACTURE OF POMPRET CAKES, ROLLS, AND
PIPES, AND OF LOZENGES, AND IN APPARATUS TO BE USED IN THE MANUFACTURE OF
SUCH ARTICLES," to be as follows:-
Our improvements in the manufacture of Pomfret cakes, rolls, and pipes,
and of lozenges, consist in forming them by means of repeated or accumulated
films, layers, or lamine of liquid or pasty material on prepared surfaces, or
dies of metal or other suitable material. We lay a film or thin layer of liquid
or pasty liquorice mixture or other material on to a prepared surface; the film
is then dried sufficiently by suitable means and another film laid on it, which
is in turn dried, and so on repeating or continuing the operation until a sheet
of the desired thickness is obtained, which on its removal from the prepared
surface can be made into rolls or pipes, or it can be passed through figuring
and cutting machines, or otherwise be made into Pomfret cakes or into
lozenges.
We form Pomfret cakes and, lozenges directly from the liquid or pasty
liquorice mixture or other material by laying the films or thin layers thereof
on to prepared plain or figured surfaces or dies of the desired form, pattern,
and size, drying the film sufficiently, then laying on another, drying again,

page_text: and repeating or continuing the operation until the desired thickness is
obtained, when the cakes or lozenges are removed from the dies or surfaces.
We also form such sheets, rolls, or pipes by dipping suitably prépared
sheets, plates, cores, or rods of metal, glass, or other suitable material, or of
liquorice or other confectionery material or combination of materials into
liquid or semifluid liquorice or other mixture, so as to form a film or layer
thereon, which is then dried and the operations repeated until the desired
thickness or size is obtained; the sheets, rolls, or pipes may then be formed
into cakes or lozenges.
We also form sheets Pomfret cakes and lozenges by alternately laying on
to prepared surfaces a film or thin layer of liquid or semifluid material, and
then dusting or laying thereon powdered dry sugar or other materials, then
drying and repeating the operations alternately until the desired thickness is
obtained.
Our improvements in apparatus to be used in the manufacture of Pomfret
cakes, rolls, and pipes, and of lozenges, consist, firstly, in the use of a cylinder
or endless sheet of copper or other suitable material, which being slowly
rotated in an enclosed space, and in contact with feed rollers, or a short end-
less sheet revolving in a trough or cistern, a thin film or layer of the liquid or
pasty material is continuously spread on its surface, which film'or layer is con-
tinuously dried by a current of air heated or otherwise passed over its surface
and through the enclosed space in which it is moved. These operations are
continued until the desired thickness is obtained, when the sheet of material
thus produced is removed from the cylinder or endless sheet on which it
had been formed,' and 'may then be made into Pomfret cakes, rolls, pipes, and
into lozenges.
'Our improvements in apparatus för förming Pomfret cakes and 'lozenges
directly from the liquid or pasty materials consist in the use of plain or figured
dies, of the size, pattern, and form 'required; attached to a cylinder for endless
sheet or other carrying apparatus, which being slowly rotated 'in' an enclosed
space, a thin film of the material is continuously laid on the dies by an endless
sheet of 'suitable fabric revolving in 'contact with them, and with a supply
roller in a trough or cistern, the quantity of such feed being regulated 'by a
"
doctor" or otherwise. The film'is continuously dried by'a current of cold 'or
heated air passed over its surface and through the enclosed space in which the
dies travel. These operations are continued until the desired thickness of
cakes or lozenges is obtained, when they are removed from the dies by suitable
means.
Our improvements in apparatus 'also consist of a system of endless chains,

page_text: or of discs or other arrangement for carrying frames, from which are suspended
sheets, plates, rods, or cores of suitable materials, which are consecutively
dipped into a cistern of liquid ingredients by the continuous rotation of the
carrying apparatus; the films or coatings thus formed on the sheets, plates,
rods, or cores are dried by passing a current of air, heated or otherwise, over
their surfaces and through the inclosed space in which they rotate.
operations are continued until the desired thickness or size is obtained.
These
In all arrangements where the finished article is removed from the sheets,
plates, surfaces, dies, cores and rods, we prepare these latter by laying thereon
a thin film of oily, fatty, or other substance, to prevent too great adhesion of
the materials to them.
Our improvements in apparatus for forming rolls or pipes into cakes or
lozenges consist in dividing the rolls or pipes transversely into the required
thickness by circular or other saws or cutters.
