I, LODI MONTAIGUE, of No. 11, Rue Villedo, in the City of Paris, in
France, Mechanician, do hereby declare the nature of the said Invention
for "AN IMPROVED TURBINE FOR DRYING SUGAR AND OTHER WATERY MATTERS," to
be as follows:-
This Invention consists in obtaining continuous working of the turbines
applied to the separation and desiccation of sugars or other matters, the solid
and liquid parts of which have to be separated. I obtain this continuous
working by causing to turn within the druin acting as sieve, a screw, the edge
of which nearly touches the sieve, and which receiving a motion slightly more
rapid than that of the sieve, forces the sweet juices or other matters to descend
with a speed which may be regulated at will by giving more or less speed to
the screw. The sieve is open at the lower part to permit the solid matters to
fall freely while the liquid matters are received in a gutter made near the
casing which surrounds the sieve, so that it is only requisite to pour the
matters to be treated into the top to gather separately at the bottom the liquid
and solid parts.
On the accompanying Drawing forming part of this my Provisional.
Specification, T, R, indicates a hopper; I, introduction pipe; M, moderator
for introduction of the sugar; P, turn-plate throwing in the matters; H,
screw; C, D, sieve; O, cylinder or casing; G, gutter; R, slab receiving the

page_text: sirups; A', shaft of the screw; B, shaft of the sieve; J", pulley driving the
sieve; L, driving pulley of U and V; U and V; J and J', turn-plates trans-
mitting the motion of L to J"; F, driving pulley; I', turn-table receiving
the sugars; E, moderator of the movements of J, J¹, and J; S, box to hold
the sugar; T, pipe for running off the oils; T', injection pipe; Ju, slab
receiving the oils from Z; N, N, gearing of E and L; Z, passage of the oils;
Y, point, to which descends the injection pipe; X and X', continuation of
the pipe T', by which the injection is spread. At O is seen the cylinder,
and at C, D, the sieve, as in ordinary turbines. The part H representing
the screw. The sugars or other matters are introduced into the turbine
by means of the hopper T, R, from which they pass by the tube I, and
this introduction is regulated by a conical valve M, or by means of a
small screw placed in the pipe I, or by other means according to circum-
stances. The sugars fall on to P, and by centrifugal force are pre-
cipitated against the sieve C, D, and the screw turning faster than the sieve,
pushes the sugar, and consequently causes it to descend with a speed pro-
portioned to the difference in the turns of the screw and the sieve. The
sugars therefore descend along the entire surface of the sieve C, D, while the
liquid parts or sirups escape by the centrifugal force through the sieve.
Arrived at D, the sugars or other solid matters fall on a turn table I', from
whence they are directed towards sacks or other receivers. The sirups or
liquids arrive on the cylinder O and run off by the gutter G on to the slab R.
The tube T¹ serves for injections on to the matters to be treated, and descends
to Y, where the injection is projected towards X and X. The turn-plate J"
gives the rotary movement to the sieve C, D, by means of the shaft B. The
screw takes its motion from the shaft A', which is moved by the pulley F.
The length of the operation may be varied according to the desire of the
manufacturers by the turn-plates L, U, V, J, J, J", which are arranged for
this purpose. The oils which fall at Z go to J by the centrifugal force,
and from thence to T pipe, which empties the small slab J.
The Drawing indicates transmission of motion by friction plates, and the
rolling is on friction rollers; but it is needless to observe that bands and
pulleys or toothed gearing may be used for transmitting the power, and the
rolling take place in any sort of bearing.
