Improvements in or relating to Infusing and like Apparatus.
I, PIERRE EUGÈNE SYLVAIN BARBÉ, of 1, Rue Alphonse, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to the methodical washing of substances: heating in a
water bath in the infusing apparatus itself: uniform wetting: straining and
generally the continuity of operations necessary, whereby simplicity, rapidity,
and simultaneousness of operations is obtained.
Fig. I of the accompanying drawing is a central vertical section through the
apparatus.
Fig. II is a sectional plan of the distributor K.
Fig. III is a plan view of the strainers, l' for coffee and Q for tea.
The left hand portion of Fig. IV is a half plan of a closed geyser and the
right hand portion a half plan of an open geyser.
The left hand strainer P having a complete or large straining area is for
coffee etc. (and would be replaced by a strainer Q for tea). Its position under
the largest hole corresponds to fresh substance.
The right hand strainer Q with a reduced straining surface is for tea (and
would be replaced by a strainer P for coffee). Its position under the smallest
hole corresponds to substances which have already been used.
The straining surface preferably consists of a metallic netting called "reps," i.e.,
a netting having warp and weft formed by threads of different diameters."
In the left hand half section (Fig. 1) the boiler part and the "pouring out"
apparatus are connected only by a series of soldered joints V, the length of which
regulates owing to its conductivity the temperature of the water falling on the
material treated by retarding it and the infused liquids in the pouring out
apparatus from cooling.
In the right hand half section the two parts are connected by a continuous soldered
joint.
The left hand section represents a closed geyser G comprising several or double
walls and without a float.
The right hand section shows an open geyser with single walls and provided
with a float F.
Water boils and is projected on the substances in drops or spray passing through
holes M. A methodical automatic circulation is obtained by means of the vessel G
which I call a 61
geyser" surrounding an inner portion of water in the boiler C,
which becomes slowly heated and communicates with the external portion through
the holes g.
The outer layer or portion of the water boils first and rises through
the central tube H. The water thus removed from the outer part of the geyser
is replaced by a corresponding amount entering from the inner part through the
holes g, stopping the ebullition and the ascension of the boiling water, until the
levels being reestablished the water boils again part of it rises and so on.

page_text: To make an infusion, the water required is introduced through the branch D
or the cock-gauge E and the burner is lit. The strainer containing the exhausted
residue is withdrawn and its contents thrown away the apparatus being turned
through half a revolution to bring the remaining strainer into position. Another
strainer with fresh substances, coffee, tea etc. is placed at the place that it before
occupied. The distributor K is put in place with its cover I and the stopper D
is inserted. The water rises owing to the pressure of the steam produced in the
tube H, and passes through the holes and h¹ of different diameters the greater
being at the side above the fresh substance: and falls into the compartments
of the distributor K: and from there into the strainers Por Q and thence into
the pouring out apparatus Q.
When steam issues from under the cover, the flame should be lowered and
the apparatus then acts as a water bath, or another operation is made. The
infused substance is poured out through the cock S.
Having described the general operation of the apparatus its constituent parts
will now be referred to more in detail with reference to the drawing.
A is any suitable source of heat.
B is the base forming a casing for the burner. Holes for the admission of
air can be closed or partly closed by a metallic netting for regulating the supply
of air to the burner.
F is a float-hollow or solid-for preventing the water from becoming too
quickly heated by the condensation of steam. is the upper hole of the closed
geyser to enable the water to escape. is an inner flange on the cover for pre-
venting water from being projected outwards. are depending walls on the
cover preventing water from splashing inwards. L are partitions dividing the
distributor into as many compartments as there are strainers.
M are hollow grooves of small section for ensuring the water--however small
the quantity may be-to pass uniformly and simultaneously through all the
holes in the distributor.
N are the lower projecting flanges of the holes which prevent the water from
falling in other than a straight line. O is a central tube secured to the-dis-
tributor K and placed round on the tube H.

Improvements in or relating to Infusing and like Apparatus.
I, PIERRE EUGENE SYLVAIN BARBÉ, of 1, Rue Alphonse, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
This invention relates to the methodical washing of substances; heating in a
water bath in the infusing apparatus itself: uniform wetting: straining and
generally the continuity of operations necessary, whereby simplicity, rapidity,
and simultaneousness of operations is obtained.
Figure I of the drawings left with my Provisional Specification is a central
vertical section through the apparatus.
Figure II is a sectional plan of the distributor K.
Figure III is a plan view of the strammers, P for coffee and Q for tea.
The left hand portion of Figure IV is a half plan of a closed "geyser" and
the right hand portion a half plan of an open "geyser."
The left hand strainer or filter P, Figure 1 having a complete or large straining
area is for coffee etc. (and would be replaced by a strainer Q for tea). A strainer P
(or Q) containing fresh material is placed under the large hole h, whilst a strainer
containing material which has already been used is placed under the small hole h'.
In Figure I in order to save space on the drawing, both a
"
coffee strainer and
tea" strainer are shown, but, in practice only one material would be employed
in the apparatus described.
a
The filter Qis preferably of conical or cylindro-conical shape, the straining
section being smaller than the general section of the filter.
The straining surface preferably consists of a metallic netting called "reps," i.c.,
a netting of wire gauze having warp and weft formed by threads or wires of
different diameters. The gauze may be of cupro-nickel or pure nickel or its
alloys.
"
In the left hand half section (Figure I) the boiler part and the pouring
out" apparatus are connected only by a series of soldered joints V, in order-by
reducing the extent of metallic connection between the two parts-to prevent
the liquid in the lower part of the container from being overheated and to allow
air to enter the "geyser" apparatus.
In the right hand half section the two parts may be connected by a continuous
soldered joint.
The left hand section shows a closed geyser or water container G provided
with double walls and having top inlet openings and outlet opening g at the
base.
The right hand section shows an open geyser with single walls and provided
with a float F, and similar outlet opening g
**
When water is poured in the apparatus through the branch it fills the
chambers G G and also surrounds them. Upon a lamp being placed beneath
the apparatus the outer layer or portion of the water is first caused to boil, and
ascends the central tube H and passes out in sprays through the openings hh'
and thence to the strainers, the water thus removed from the outer part of the
geyser is replaced by a corresponding amount from the chambers G, which
water being cooler than the outer portion momentarily stops the ebullition and
ascension of the water, until, the levels being re-established, the water boils
again, and part of it ascends the tube H and passes out through the holes h h¹.
To make an infusion, the water required is introduced through the branch F,
or the cock-gauge or measurer E, or a vessel containing the exact amount of
water required, to facilitate filling and to save time, and the burner is lit. The
first strainer containing the exhausted residue is withdrawn and its contents
thrown away, and the second remaining filter is turned in the apparatus half a
revolution. Another strainer or the original first strainer with fresh material,
coffee, tea etc. is then placed in the position that the preceding filter occupied
before. The distributor K is put in place with its cover I and the stopper D is
inserted. The water ascends (owing to the pressure of the steam produced) in
the tube H, and passes through the holes and h¹ of different diameters the

page_text: greater being at the side above the fresh substance and falls into the compart-
ments of the distributor K and from there into the filters P or Q and thence
into the pouring out apparatus R.
When steam issues from under the cover, the flame should be lowered and
the apparatus then acts as a water bath, or another operation is carried out. The
beverage or liquid is poured out through the cock S.
Preferably the parts in contact with the liquid such as the walls of the strainers
or filters, pouring out part, rising and heating tubes, boiler and geyser" are
constructed of or lined with enamelled sheet metal, or glass.
Having described the general operation of the apparatus its constituent parts
will now be referred to more in detail with reference to the drawing.

strainers. are the feet or supports of the geyser and S an optional pourer
addition which may be of any desired form of construction.
Although only two strainers are shown arranged side by side in the drawing,
it is evident that three or more could be used, their shape in cross-section would
then be that of sectors of a circle instead of half-circles.
