Invention for "A NEW AND IMPROVED APPARATUS FOR DRYING UP BAGAUZE
AND OTHER MATERIALS," communicated to me by Auguste Alexandre
Rampant, a person resident at Saigon, Cochin China, Architect, upon the.
condition (amongst others) that I, the said Henri Adrien Bonneville,
my executors or administrators, by an instrument in writing under.
my, or their, or one of their hands and seals, should particularly.
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :—
This Invention relates to dessicating almost instantaneously the bagauze
of sugar cane houses and other materials by utilizing the waste heat from
generators, and consists of a new and improved stationary or portable
apparatus consisting of a hollow cylinder of sheet iron or other suitable
metal, heated underneath by the waste heat or fire.
The top of the cylinder provided with evaporating pipes is covered
with an insulating paste formed with two parts of clay or silicious sand
and one part of sawdust treated with sulphate of copper, and it is
further surrounded by a shell of masonry or of some suitable metal.
Inside the said cylinder rotates an Archimede's screw or helix, to the
shaft of which the rotating motion is imparted through the gearing of
the motive power of the works. At one end of the said cylinder is a
hopper provided with a cutting apparatus, into which is thrown the
bagauze or other material to be dried, which is gradually carried along?

page_text: the cylinder by means of the spiral screw. towards its other end, where
being dried it is thrown out of the cylinder on to an incline through an
opening in the end plate of the cylinder.
Having thus briefly described the said apparatus I am now going to
describe the same more particularly, reference. being had to the accom-
panying Drawings, in which Fig. I. is a longitudinal vertical section of
the apparatus; Fig. II., a longitudinal elevation of the same; Fig. III.,
an end view of the same; and Fig. IV., a transversal section of the same.
In these Figures the same letters of reference indicate corresponding
parts.
The dimensions of the said apparatus vary according to the motive
power by means of which the motion is imparted to it, and the size of
the works. It is made of iron, sheet iron, and cast iron, and the rotating
motion is imparted to it by means of a belt passing over a pulley
mounted on the main shaft of the works at the rate of one turn of the
helix a minute.
The apparatus is formed with a fire casing A, a cylinder B, and a
rotating helix C therein, and an insulating shell. The shell A is made.
of strong sheet iron joined together in sheets bolted and rivetted on angle
or band iron resting on the ground if the apparatus is immoveable, or
upon rollers if it is moveable. The flames circulate in this casing, made
with masonry or metal surrounding the external surface of the enclosed
cylinder B, in which the helix rotates.
The mode of the introduction of the flames into the apparatus as well
as that of their exit is left to the discretion of the engineer, who should
be guided according to the arrangement of the works. But whatever
may be the system adopted it is absolutely indispensable that the flames
should go over the whole length of the apparatus from one end to the
other.
To regulate the work it will be easy to make use of a damper at the
point of entrance of the flames, by means of which they could quicken
or moderate at will the introduction of the flames into the apparatus. It
will also be useful to place upon the top part of the casing A, near the
man-hole D, an indicator telling the exact degree of the dry heat of the
flames.
The cylinder B is of an equal diameter from end to end. It is made
of strong sheet iron rivetted and jointed externally, the internal sides

page_text: being perfectly smooth. The two ends of the said cylinder are adjusted
to the casing A by firmly rivetted corner iron. At the top near the
outlet E, through which is thrust the bagauze, coming out of com-
pressing cylinders, a slope F is formed in the shape of a funnel about
the diameter of the cylinder B, through which the damp bagauze is
introduced into the apparatus.
The outlet of the dry bagauze G at the other end of the cylinder is
elongated beyond a half spiral of the helix C herein-after mentioned.
At the lower part of the outlet is fixed an incline upon which the dry
bagauze is automatically thrown by the rotation of the helix. .
At the top of the cylinder B áre fitted steam escape pipes passing
through the upper part of the casing A, by which the water with which
the bagauze is saturated on its insertion in the apparatus escapes as
steam.
An overheating apparatus may be placed under the apparatus to give
back its lost force to the condensed steam coming from the engines of the
works.
The iron axis K of the helix, made of variable size, according to that
of the helix C, is hollow, and each end of which rests on an iron
pedestal L.
These pedestals are moveable, and are under the action of
screws, which serve to control the working of the helix and to prevent
obstructions. At the middle this axis is sustained by an iron rod M, the
lower end of which is provided with a socket in which the axis turns,
while the upper end is threaded to receive above the casing A a key N,
by means of which the axis may be raised or lowered at will. Along
the rod or support above described a little copper pipe is fitted for
lubricating.
In order to place this support M a man-hole D is pierced in the
casing A, with a double joint shutting closely to prevent the intro-
duction of the flames into the cylinder.
The sheet-iron spiral C fixed on the axis K is provided with three
parallel and alternate iron rods, each one armed with two S, placed on
the same line as the circumference of the helix and fulfilling the work
of "rummagers," whose length should not exceed 0.33. Beyond these
rummagers on the same rods and each side of the spiral of the
helix, "pickers up" O, provided with straight and stiff points, are.

page_text: rummagers
placed, which stand out towards the external face of the helix, being
half the designated size of the S above. These
" and
"pickers up" are used to move about and divide the bagauze in the
cylinder constantly.
The front of the apparatus is closed by means of a cast-iron plate P,
on which are fixed the pedestal L and the screw S, used for regulating
the motion of the helix. All is in one piece. The cylinder fits in the
said plate P, to which it is firmly connected by means of three screw
nuts. This plate allows and facilitates the placing and the taking out of
the helix.
The front pedestal L is supported by two brackets T.

The diameter of the helix should be 0.04 less than that of the
cylinder, so that a slight friction will be produced in the lower part of
this cylinder, and a sufficient space shall exist in the upper part to main-
tain a permanent current of air necessary for the clearance of the steam.
The quantity of water to be extracted by evaporation from the fresh
bagauze to make excellent fuel of it is from 40%. The current of air
between the inlet E and the outlet G produced by the rotation of the
helix in its cylinder facilitates the expulsion of this steam through the
steam pipes during the operation of the drying. The lower part of
the cylinder rests on two iron supports Y.
The rotating motion is imparted to the helix by means of the gearing U,
to which the motion is transmitted by a pulley mounted on the axis of
the sugar cane cylinder. The motion of the divider X depends on the
gearing U.

The apparatus may be if desired surrounded by a double casing or
jacket, made of wood or sheet iron, to prevent the radiation of the heat.
Between this jacket and the casing A an annular space from 0-03 to 0.05
is left, which will be filled with an insulating compound formed of two
parts of clay or silicious sand and one of sawdust treated with sulphate
of copper mixed up and reduced to a damp paste strongly compressed in
the above-mentioned space.
Having thus described the nature of the said Invention, and the manner
of carrying it into effect, I would have it understood that I do not confine
myself to the precise details above enumerated, as these may obviously
be modified without departing from the principle of the Invention, but

page_text: what I claim and desire to secure by the said Letters Patent is a new
and improved stationary or portable apparatus surrounded by an insu-
lating compound for the purpose of dessicating the bagauze, constructed
and arranged as above described, and represented in the accompanying
Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereunto set my hand and seal, this Twentieth day of October, in
the year of our Lord One thousand eight hundred and seventy-
four.
