Office of the Commissioners of Patents, with his Petition, on the
21st October 1865.-A communication from Monsieur Joseph Jules
Derriey, residing at No. 21, Ancien Chemin de Ronde Ménilmontant,
Boulevard Belleville, Paris, in the Empire of France.
I, HECTOR AUGUSTE DUFRENÉ, of the General Patent Offices, 10,
Rue de la Fidélité, Paris, in the Empire of France, and 4, South Street,
Finsbury, London, Civil Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY POR THE MANUFACTURE OF
LOZENGES, WAPERS, OR PASTILLES OF PASTY MATERIALS," to be as follows, that
is to say:-
The Invention communicated to me consists in an improved arrange-
ment or construction of machine for making pastilles, or lozenges, and other
similar articles, and is as follows:-
This machine is mounted on a strong iron frame, and consists of a
marble slab for supporting the paste to be made into pastilles, for which
operation three series of cylinders are employed, the space between them
being regulated at will to give the pastilles the required thickness. During
the action of the cylinders they cause the paste to advance a distance
equal to the required size of the pastilles in such manner as to leave but
very little cuttings between the pastilles that are formed from the rolled
Daste.

page_text: Behind the laminating cylinders is an endless cloth for conducting the
rolled paste in front of the machine, where it is made into pastilles in the
following manner:-In front of the machine is a hollow cylinder con-
taining all the pastilles, which are cut and stamped in relief on both sides;
at each stroke of the piston this cylinder makes half a turn and deposits
the pastilles in a line on a plank underneath, which gradually advances in
the play of the machine. This plank is placed empty at the back of the
machine, and is withdrawn in front loaded with pastilles. In front of
this cylinder is another endless cloth, which carries with it the cuttings
separated from the pastilles, which cuttings are doubled several times to
enable a larger quantity to be taken at once, when they are again passed
under the machine to be made into pastilles. This machine can be worked
by hand by means of a crank or by any other motive power, and will give
according to its size from 30 to 40 strokes of the piston per minute,
producing at each stroke from 10 to 40 pastilles of any desired form. The
crank transmits movement to two gearing wheels, one of which in turning
gives by means of an excentric a to-and-fro movement to the stamp carrier,
and communicates to the other placed underneath an alternate rotative
movement, which, when the pastilles are cut and enclosed in the cutting
cylinder causes the latter to make half a turn, so that the pastilles may fall
on the plank underneath. The driving shaft carries a regulating fly-wheel,
and gives motion to a wheel carrying an excentric pin attached to a
connecting rod, which changes the rotative movement to a to-and-fro
movement and causes a click to catch on a ratchet wheel, which turns the
rolling cylinders, one of which turns the other. The more excentric the
pin is the greater will be the movement communicated to the cylinder, so
as to roll a quantity of paste proportionate to the required size of the
pastilles. In putting the click in or out of gear a continuous movement
is communicated to the cylinder, which in 4 or 5 turns causes the paste to
advance just under the stamps, when there the click is lowered, and the
paste continues to be rolled in proportion as the pastilles are cut. This
operation permits of working with greater rapidity.
