Improvements in Apparatus for Automatically Manufacturing Cold
Syrups of a Determined Density.
We HERMANN KLEIN and GEORGES DETHAN, Builders, of Rue Baudin, Paris
in the Republic of France, 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 :-
This invention for improvements in apparatus for automatically manufacturing
cold syrups of a determined density has for its object to produce automatically and
continuously and in any desired quantity according to the dimensions of the
apparatus and the quantity of materials employed clear and colourless cold syrups
of a predetermined density not containing the slightest trace of glucose and not
liable to evaporation: and consists essentially of two vessels separated by a
filtering medium, the upper vessel serving to contain the ingredients employed and
the lower vessel serving to receive the manufactured syrup and being provided with
a draw off cock, with a means for indicating when the required density is attained
and with an inlet for air.
In the accompanying sheet of illustrative drawings
Fig. 1 shows in vertical section and in horizontal section one form of apparatus
constructed according to this invention, and
Fig. 2 shows in similar views a inodified construction.
The perforated cylinder F is supported by its rim from the upper edge and
within the cylinder A made of silvered copper or other suitable material not acted
upon by the ingredients employed. The sieve II of metallic wire, perforated sheet
iron or other suitable material is suspended in the cylinder A below the bottom of
the perforated cylinder F, and is surrounded by a felt cloth, flannel or other suitable
fabric I. The sieve H serves to support paper pulp or other suitable filtering
medium and above it but below the bottom of the cylinder F is a second sieve G.
The glass tube B communicates with the cylinder A and indicates the level of the
liquid therein and also by means of the float 6 having the desired density when the
liquid has attained that density. The tube B. is provided at its lower end with a
three-way cock so that the contents of the tube can be emptied and fresh syrup be
admitted from the cylinder A to determine its density. Air is admitted to the
lower part of the cylinder A but above the surface of the syrup contained therein
by means of the tube C. The contents of the cylinder A are withdrawn as desired
by means of the syphon tube D and cock E.
In the arrangement shown in Fig. 2, the cylinder A¹is of glass provided at its
bottom with a draw off cock E' and is not provided with a glass tube, the density
being indicated by a float within it. The cylinder F is made of earthenware or
other suitable material and rests by its rim on the upper edge of the cylinder A¹.
It is open at the bottom where it is provided with an internal rib serving to support
the sieves H and G. Air is admitted to the surface of the syrup in the lower part
of the cylinder A through the holes C¹ in the upper edge of the cylinder F'.
The operation is as follows
―:
The apparatus is mounted in any convenient manner and filtering medium is
inserted between the two sieves G, H and the cylinder F or F¹ containing the
ingredients for producing the syrup.introduced in place as shown. When the syrup
has attained the predetermined density the float rises and indicates the height to
which syrup of this density extends, and this quantity can then be drawn off by
means of the cock E or E¹.
It is thus possible without taking any notice of the quantity of the ingredients or
of the syrup formed to draw off syrup of the required density.

page_text: 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. The arrangement of apparatus for automatically manufacturing cold syrups of a
determined density consisting of the perforated cylinder For the bottomless
cylinder F supported within the upper part of the cylinder A or A and of the
means for admitting air to the lower part of the cylinder A or A¹ substantially
as hereinabove described.
2. The arrangement of apparatus for automatically manufacturing cold syrups of
a determined density consisting of the perforated cylinder For the bottomless
cylinder F supported within the upper part of the cylinder A or A' and of the two
sieves between which is a filtering medium which separates.the contents of the two
cylinders substantially as herein before described.
3. The arrangement of apparatus for automatically manufacturing cold syrups
of a determined density consisting of the perforated cylinder For the bottomless
cylinder F supported' within the upper part of the cylinder A or A¹, of the two
sieves G and H between which is a filtering medium separating the contents of the
two cylinders, of the means for admitting air to the contents of the oylinder A or A',
and of the means for drawing off the syrup substantially as hereinbefore described.
4. The arrangement for determining when the syrup has attained the required
density consisting of a float of the required density in an indicator tube provided
with means for drawing off and replacing from the vessel the contents or in the
vessel itself substantially as hereinbefore described.
5. The apparatus for automatically manufacturing cold syrups of a determined
density substantially as hereinbefore described with reference to the drawings.
