Improvements in Means or Apparatus for Drying Slabs of Sugar,
Applicable for Heating and Cooling other Articles and for
Analogous Operations.
I BENJAMIN EDWARD REINA NEWLANDS of 27 Mincing Lane in the City of London
Analytical Chemist do hereby declare the nature of this Invention to be as follows:-
1. My Invention has for its object to provide simple and efficient apparatus especially
adapted for effecting the drying of slabs or sticks of sugar but applicable also to
analogous operations such for example as to the drying or cooling of other substances
or articles or the subjecting of them to the action of gases or to the baking of
biscuits or operations of an analogous character in a continuous and automatic manner.
According to my invention I provide an endless band of carriers moving first in one
direction and then in the opposite direction in ducts or casings. These ducts or
casings are most conveniently arranged parallel to each other and connected at top
and bottom of each end by a curved portion so that the said ducts or passages
conform to the path taken by the carriers as they pass in endless band fashion over
pulleys. At a convenient portion of the ducts or casings there is a feeding inlet into
which the articles are fed so that they are received by the carriers and by them
taken through a portion of the ducts or passages in one direction and then are taken
by the said carriers in the other direction through another portion of the ducts or
passages they, as the band of carriers change their direction of travel, falling over
onto their other sides and when the said carriers reach any convenient point of their
travel the articles they support slide or are moved off from them and pass through a
discharge outlet into a receiver or into a receptacle. The ducts or passages com-
municate with an inlet and an outlet for the heated air or other agent. The carriers
are preferably perforated or reticulated and the, feeding may be effected by an
automatic feeding device which is moved to cause a slab or the like to be fed onto
oach carrier as it is presented at the feeding opening. The feed and outlet openings
may be covered by flaps which are opened by the slabs or the like as they pass onto
and from the carriers.

Improvements in Means or Apparatus for Drying Slabs of Sugar,

Analogous Operations.
I BENJAMIN EDWARD REINA NEWLANDS of 27 Mincing Lane in the City of London
Analytical Chemist do hereby declare the nature of this Invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
My Invention has for its object to provide simple and efficient apparatus especially
adapted for effecting the drying of slabs or sticks of sugar but applicable also to
analogous operations such for example as to the drying or cooling of other substances
or articles or the subjecting of them to the action of gases or to the baking of
biscuits or operations of an analogous character in a continuous and automatic manner.
According to my Invention 1 provide an endless series or band of carriers moving
first in one direction and then in a returning or opposite direction in ducts or a
casing. The ducts if not made as one casing are most conveniently arranged parallel
to each other and connected at top and bottom of each end by a curved portion se

page_text: that the ducts or passages conform to the path taken by the carriers as they pass in
endless band fashion over pulleys. At a convenient portion of the ducts or casings
there is a feeding inlet into which the articles are fed so that they are received by the
carriers and by them taken through a portion of the ducts or passages in one direction
and then are taken by the said carriers in the other direction through another
portion of the ducts or passages they, as the band of carriers change their direction
of travel, falling over onto their other sides and when the said carriers reach any
convenient point of their travel the articles they support slide or are moved off from
them and pass through a discharge outlet into a receiver or into a receptacle. The
ducts or passages communicate with an inlet and an outlet for the heated air or other
agent. The carriers are preferably perforated or reticulated and the feeding may be
effected by an automatic feeding device which is moved to cause a slab or the like to
be fed onto each carrier as it is presented at the feeding opening. The feed and
outlet openings may be covered by flaps which are opened by the slabs or the like as
they pass onto and from the carriers.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
The accompanying drawings illustrate sections at right angles to each other of an
apparatus constructed according to my Invention.
A is a casing provided at B with an inlet for the hot air or other agent to the
action of which the substances under treatment are to be subjected. C is, an outlet
for the said air or agent. D is the opening for the introduction of the articles or
matters to be treated and E is the outlet for them. Within this casing a duct a is
formed through which the substances to be treated are caused to pass in contact with
the hot air or agent.
In the casing A are mounted upon shafts F sprocket wheels or drums G over
which are passed chains H to which are secured the carriers or boxes I for carrying
the articles to be treated. These carriers or boxes are preferably made of perforated
corrugated sheet iron. They can most conveniently be attached to the chains_by
bolting them to flanges formed on the links of the chain. Either of the shafts Fis
driven by any suitable motor at a slow rate or in accordance with the time during
which the articles are to be submitted to the action of the hot air or the like.
carriers or boxes have openings at their ends into which the articles or matters to be
treated are fed and as the said carriers or boxes are carried upwards they pass over
the upper sprocket wheels and are turned over and then the carriers or boxes descend
and the articles or matters are discharged from the carriers or boxes as they move
over the lower sprocket wheels.
The
The sprocket wheels may have either a continuous motion or they may have an
intermittent motion so that the boxes or carriers stop for a short time for feeding the
articles or matters into them. If automatic feeding be resorted to it may be done by
any suitable arrangement such as is well known in connection with printing machines
for feeding sheets of cardboard intermittently.
The feed and outlet openings for the articles or matters under treatment may be
covered by flaps which are opened by the articles or matters as they pass into and
from the carriers or boxes.
I have shown the apparatus as arranged in a vertical position but it is not essential
that it should be arranged in that position. For instance it may be arranged
horizontally and then in order to prevent the slabs or articles in the carriers or boxes
from dragging against the bottoin of the casing A there may be an endless web
arranged as a false bottom to follow the movement of the carriers or boxes as the
slabs or articles rest upon them.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
T
.

page_text: matters to be treated so arranged in a casing that they move round in endless band,
fashion substantially as herein before described.
2. In an apparatus for the purposes indicated perforated or reticulated carriers or
boxes arranged upon endless bands or webs and having motion imparted to them so
that they move round in endless band fashion in a casing and are presented before a
feed opening then pass along in one direction and turn over and pass in the opposite
or return direction and then are presented before a discharge opening substantially as
hereinbefore described.
3. The arrangement and combination of parts constituting the apparatus herein-
before described and illustrated in the accompanying drawings.
