PROVISIONAL SPECIFICATION.
Improvement in Apparatus for Liquoring Sugar.
I, FRITZ SCHEIBLER, of Burtscheid-Aachen, Kingdom of Prussia, Sugar
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the liquoring of blocks of sugar contained in molds
which are open on two opposite sides, and the improvement consists in the con-
struction of an apparatus in which a plurality of such blocks of sugar still con-
taining the green syrup, are brought on one side in contact with fine liquor under
pressure, while on the other side they are exposed to the action of a sucking
appliance.
The apparatus comprises two sets of open frames corresponding to the size and
shape of the sugar-molds and having each two perforated lugs by which they are
strung on horizontal bars fixed between standards, the frames being thus movable
on the said bars. Moreover there are two head-plates having each a shallow
recess of the same height and breadth as the inside of the frames, one of these
head-plates being integral with one of the standards, while the other one is strung,
alike to the frames, by means of perforated lugs on the horizontal bars. In alter-
nation with the frames and the head-plates there are mounted movably on the
horizontal bars carriers for the sugar-molds. Of the frames and the head-plates
the alternate ones, say the frames of odd numbers, are connected at the bottom by
means of flexible tubes to a pipe leading to an overhead reservoir containing fine
liquor, while the two head-plates and the frames of even numbers are connected
at the top by flexible tubes to a pipe leading to a vessel communicating with the
suction device. The former frames I shall call the liquor-frames, the latter the
syrup-frames.
When this apparatus is to be used, the molds filled with the sugar to be liquored,
are placed on the said carriers, and all the frames and the molds are pushed in
contact with each other and with the fixed head-plate, and finally pressed together
by the movable head-plate and a screw working in the standard in rear of the
movable head-plate. By means of packings complete tightness of the joints
between the frames, the molds and the head-plates is secured. Now the fine
liquor is admitted to the liquor-frames, while the air is allowed to escape through
vent-cocks until the frames have become filled; on the other hand the sucking-
device is caused to act on the syrup-frames. The fine liquor will then pass from
one side into each of the sugar-blocks, while the green syrup flows out from the
other side to collect in the syrup-frames and finally to rise into the aforesaid vessel
in which its quantity may be determined by means of a gauge-glass.
At the end of the operation the liquor and the green syrup contained in the
frames and the head-plates are drawn off separately, the movable head-plate is
screwed back, and the frames and mold-carriers are shifted apart in view of allowing
the molds with the liquored sugar to be removed.

Improvement in Apparatus for Liquoring Sugar.
I, FRITZ SCHEIBLER of Burtscheid Aachen, Kingdom of Prussia, Sugar
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is performed to be particularly described in and by the following
statement :-
My invention relates to the liquoring of blocks of sugar contained in molds
which are open on two opposite sides, and the improvement consists in the con-
struction of an apparatus in which a plurality of such blocks of sugar still con-
taining the green syrup, are brought on one side in contact with fine liquor under
pressure, while on the other side they are exposed to the action of a sucking
appliance.
The apparatus comprises two sets of open frames corresponding to the size aud
shape of the sugar-molds and having each two perforated lugs by which they are
strung on horizontal bars fixed between standards, the frames being thus movable
on the said bars. Moreover there are two head-plates having each a shallow
recess of the same height and breadth as the inside of the frames, one of these
head-plates being integral with one of the standards, while the other one is strung,
alike to the frames, by means of perforated lugs on the horizontal bars. In alter-
nation with the frames and the head-plates are mounted movably on the horizontal
bars, carriers for the sugar-molds. Of the frames and the head-plates the
alternate ones, say the frames of odd numbers, are connected at the bottom by
means of flexible tubes to a pipe leading to an overhead reservoir containing fine
liquor, while the two head-plates and the frames of even numbers are connected
at the top by flexible tubes to a pipe leading to a vessel communicating with the
suction device. The former frames I shall call the liquor-frames, the latter the
syrup-frames.
In order to make this Specification more easily intelligible reference is had to
the accompanying drawings in which similar letters denote similar parts throughout
the several views.
Fig. 1 is a longitudinal section through the apparatus and Fig. 2 a transverse
section.
The frame is similar to that of a filtering press and consists of the rear stationary
head-piece T having a standard P affixed thereto and the front plate T¹ mounted
on standard P', the said standards being connected together by rods G G¹. On
these bars G G are strung alternatively by means of perforated lugs h¹ the liquor
and syrup frames C and V and furthermore the supporting angles S for the molds,
said supporting angles alternating with the frames C and V. The frames C are
connected by a pipe system C to a vessel C containing fine liquor whilst the
frames V are connected by a second pipe system V' to the vacuum appliance. The
supporting frames S are each adapted to hold two molds arranged one above
the other, said molds being filled with sugar still containing green syrup. The whole
series is closed by the moveable head plate T having screw spindlet rigidly attached
thereto and loose nut t¹ mounted in the standard P and provided with a hand
wheel by means of which the said head plate may be closed up or withdrawn.
The stationary and moveable head plates T and T' also form half frames V which
are connected to the pipe system V. All the frames V and C as also the half
frames at T T are provided with india rubber packing onto which the edges of
the molds M close leaving the two open sides of each mold free to communicate
with the frames V and C respectively. When all the frames and molds are
arranged in their respective places the move-head plate T¹ is closed onto the
series by means of the hand wheel and thus all joints tightened up. Thus each
mold will communicate on one side with a liquor frame C on the other side with a
syrup frame. The frames V and C are advantageously connected to their respective

page_text: pipe systems V¹ and C¹ by means of flexible tubes and co. The pipe V¹ leads
to a receptacle V2 which is provided with a graduated gauge glass V through
which the amount of green syrup expressed may be read off, and a cock v¹ by
means of which it may be placed in communication with a suction pump or
appliance for the purpose of exhausting the syrup frames V. The pipe C¹ leads
to the receptacle C for the fine liquor and is provided with a stop cock c¹. Both
the liquor and the syrup frames are provided with outlet cocks c and the former
communicating by short pipes with a collecting trough C³ the latter by means of
pipes and gutters us with a separate trough V, so that all frames may be emptied
after the completion of the process. The surplus liquor collected in the trough C³
may be pumped back into the reservoir C².
In order to keep the amount of surplus liquor down to a minimum the frames C
are only allowed sufficient capacity to enable the liquor to act equally on the whole
crystalline surface exposed thereto.
As the frames C are emptied separately each is provided with a vent cock &³,
having cup but as the frames V are exhausted simultaneously and in common
with the pipe system V₁ and vessel V' it is only necessary to provide the latter
with a vent cock v.
In order to loosen all the frames simultaneously, after the operation has been
completed, two rods H H' are passed through second perforations in each lug of
every frame and supporting angle, said rods having collars ¹ between each lug and
a head to engage behind the moveable head plate T' so that, on retracting the
said head plate by means of the screw spindle, all frames will be drawn apart by
the collars.
When the apparatus is to be used, the molds M filled with sugar to be liquored
are placed in the carriers S and all the frames C and V and the molds M are pushed
together and against the stationary head plate T and finally pressed together by
the moveable head plate T¹, screw spindle t and handwheel t. By means of the
packings complete tightness of all joints is secured. The cock is now opened
and fine liquor from the receptacle C' admitted at a pressure of about 1 atmo-
spheres to the frames C, the air being allowed to escape through the vent cocks c³
until the frames are full, which can be seen by the fine liquor entering the cups
of said cocks. The suction appliance is now put into action thus exhausting the
receptacle Vs, pipe system V₁ and frames V. The fine liquor will then be pressed
from one side into each of the sugar blocks, thus driving out and taking the place
of the green syrup, which flows out from the other side to collect in the syrup
frames V and finally to rise into the vessel V' in which its quantity, may be
determined by means of the graduated gauge glass V*.
At the end of the operation, the liquor and the green syrup contained in the
frames V and C and the head plates are let off separately into the troughs C
and V, the moveable head plate T¹ is screwed back and the frames and mold
carriers shifted apart in view of allowing the molds with the liquored sugar to be
removed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is performed, I declare that what I
claim is:
1. The combination of the liquor frames C having vent cocks c³, syrup frames V,
strung alternately on horizontal guide rods G G', the sugar molds M supported by
angles E also moveable on said rods G G and arranged so that the molds sup-
ported on each angle lie between a liquor frame and a syrup frame, the stationary
head plate T and moveable head plate T¹, elastic packing surfaces between the
said molds and frames, pipe connections from each frame C to the liquor vessel C³,
pipe connections V₁ from the frames V to the suction appliance and means for
letting off the contents of frames V and C after completion of the process substan-
tially as described.
2. The combination of liquor frames C, and syrup frames V, and molds M

page_text: arranged as described, on rods G G¹, stationary head plate T and moveable head
plate T¹ having spindle t, nut t¹ mounted in standard P₁ and worked on said
spindle t by handwheel t, pipe connections C' with stop cock from frames C to
the liquor reservoir C, pipe connections V' from chambers V to the vacuum
appliances, and a syrup receptacle V having graduated gauge glass V4, stop
valve v and vent cock, said receptacle being arranged in the pipe system V
substantially as described and shown."
