Improvements in and connected with Centrifugal Machines for
Sirups and other Liquids.
I HERMANN ANDREE of Schulan near Wedel in the Province of Sleswig-
Holstein Empire of Germany Manufacturer 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 relates first to a device for rendering regular and at the same time
accelerating the flowing-off of the sirups from centrifugal machines so as to obtain
a better separation of the same, and secondly to an arrangement whereby the
centrifugal machine having several outflow grooves and pipes of similar shape is
combined with a funnel capable of being rotated below which there are provided
several collecting grooves from whence the sirups of different degrees of
concentration are driven by means of pumps into separate vessels
afterwards into receiving pipes connected to a piping supplied with compressed
air the sirups being thus forced into the centrifugal machines in much less time
than hitherto.
and
In ordinary centrifugal machines the outflow grooves of the machine (when
arranged with opposite inclinations) does not allow of a regular discharge of liquid
quick enough to insure a good separation of the sirups, as the wind produced at the
circumference of the machine during its rotation accelerates the flowing off, of
the sirups on the inclines descending in one direction whilst it retards the flowing-
off on the inclines in the opposite direction. In order therefore to obviate this
and to obtain a completely uniform flowing-off of the sirup I make the outflow
grooves all inclined at the same side, as hereinafter more clearly described and
by this means also the flowing-off of the sirup is accelerated as a greater
inclination can be arranged than is possible in machines with slopes opposite to
each other.
I will now proceed to describe a centrifugal machine made and worked
according to my improvement reference being made to the accompanying sheet of
drawings.
Fig. 1 is a cross-sectional elevation of my improved centrifugal machine.
Fig. 2 is a sectional plan taken on line Y, Y of Fig. 1.
Fig. 3 is a plan showing the arrangement of the outflow and collecting grooves
and
Figs. 4 and 5 are respectively side and front elevations illustrating the general
arrangement and connection of the several parts.
Similar letters of reference denote corresponding parts in each view.
The collecting-casing a of the centrifugal machine is provided with four
slopes all inclining to the same side and extending to the middle height
of said casing a. At the lowest points of these slopes there are arranged
pipes, leading to the funnel e which latter is arranged with suitable
gearing and and a handle as shown at Fig. 4 so that it may be easily
rotated when required and have its discharge end placed over any one of the
collecting grooves c¹ c² c³ c¹ or c². From these grooves the sirup is by means of
pumps 3 and 4 forced through suitable pipes into the vessels k¹ k² k³ k^
and and finally into the receiving pipes which are connected to the piping n
containing compressed air.
The operation and working of my said improvements is as follows,
The sirup flowing off from the centrifugal machine by the slopes ² and
(the quantity flowing off being the same on the four slopes in consequence of their
similar inclination) and of the action exerted equally on each of them by the wind

page_text: caused by the rotation of the machine, flows through the pipes b', 62, 63, and 64 and
through the funnel e into one of the grooves c¹ c2 cc or according to the position
of the discharge end of the funnel e so that a separation of sirups of different
degrees of concentration is easily effected. Thus the sirups according to their
degree of concentration are pumped by means of pumps ³ ³ ³ h or h³ into
the vessels 1, 2, 3 kork and thence into the receiving pipes and are
finally by the pressure of the compressed air flowing through the piping n
driven back into the centrifugal machine where they are to be employed as treacle
sirup.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In centrifugal machines for sirups and other liquids: arranging the collecting
casing a with several slopes for the outflow of the liquid all the said slopes
being inclined to the same side, in combination with outflow pipes arranged at
the lowest point of each slope substantially as described and used for the purpose
specified.
2. In combination with the casing slopes and pipes as aforesaid, the employment
of a funnel e capable of; being rotated so that its discharge end can be placed over
any of the collecting grooves c¹ c² c³ct and cand of pumps 2 h³ or serving
to drive the treacle sirups into the vessels kl k² k³ kand and into the receiving
pipes which are connected to the piping n supplied with compressed air all
arranged substantially as described and used for the purpose set forth.
