Improvements in Apparatus for use in Making and Dispensing
Infusions.
We, VICTOR GEORGE OSTERROTH, of 15, Foulden Road, Stoke Newington, in
the County of London, Gentleman, WILLIAM JOSEPH BROWN, of 75, Elmir Road,
West Green Road, Tottenham, in the County of Middlesex, Engineer, and Jous
ROBERT BEER, of 26, Victoria Avenue, East Ham, in the County of Essex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for use in making and dispensing infusions
such as infusions of tea or of coffee or the like in shops or in cases where a
considerable quantity has to be made at one time and the said invention has for
its object to provide apparatus by means of which clearer infusions are made and
the water in the boiler is prevented from becoming contaminated by the in-
fusions and to generally improve and render such apparatus more efficient.
According to this invention a passage for the water from the boiler, to the
infusing vessel or to each infusing vessel is provided separate from that, or those,
which leads, or lead, to the container. The strainer into which the water from the
boiler passes is situated in the upper part of the infusing vessel or vessels, the tube
supplying the water at the upper part of the said infusing vessel or vessels and
into the said strainer and any fur or other like impurity cannot get into the
infusion when it is passed from the infuser or infusers into the container. To
keep the water in the boiler at a uniform level a separate feed valve is used in a
casing connected to the boiler by tubes at top and bottom and provided with a
float te regulate the water supply so that the float and working parts of the
valve are not liable to be corroded or coated with fur or deposit as has hitherto
been the case because the water in the valvular arrangement being placed at any
convenient distance from the boiler can be maintained at a much lower tem-
perature than that in the boiler. Moreover this arrangement allows of ready
access being had to the valve for repairs.

ROBERT BEER, of 26, Victoria Avenue, East Ham, in the County of Essex,
Engineer, do hereby declare the nature of this invention and in what munner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to apparatus for use in making and dispensing infusions;
such as infusions of tea, or of coffee, or the like in shops or in cases where a
considerable quantity has to be made at one time; and the said invention has
for its object to provide apparatus by means of which clear infusions are made
and the water in the boiler is prevented from becoming contaminated by the
infusions and to generally improve and render such apparatus more efficient.
According to this invention a passage for the water from the boiler to the infusing
vessel or to each infusing vessel, is provided separate from that, or those, whien
leads, or lead, to the container. The strainer into which the water from the
boiler passes is situated in the upper part of the infusing vessel, or vessels, the
tube supplying the water at the upper part of the said infusing vessel or vessels,
and into the said strainer, and any fur, or other like impurity, cannot get into
the infusion when it is passed from the infuser, or infusers, into the container.
To keep the water in the boiler at a uniform level a feed valve is used in a casing
situated at any desired distance from the boiler and connected to it by tubes at
top and bottom and provided with a float to regulate the water supply so that
the float and working parts of the valve are not liable to be corroded or coated
with fur, or deposit, as has hitherto been the case, because the water in the
valvular arrangement being placed at any convenient distance from the boiler
can be maintained at a much lower temperature than that in the boiler. More-
over this arrangement allows of ready access being had to the valve for repairs.
We will describe with reference to the accompanying drawings an apparatus
constructed in accordance with this invention provided with two infusing vessels
and one container. Figure 1 is a side elevation and Figure 2 is a sectional eleva-
tion of the infusing and containing vessels and the controlling devices in con-
nection therewith these parts being conveniently situated above the counter.
Figure 3 is a vertical section on the line 1, 2 Figure 1. Figure 4 is a horizontal
section on the line 3, 3. Figure 1 and Figures 5 and 6 are part vertical sections
respectively on the lines 5, 5 and 6, 6 Figure 4. The section of this part shewn
in Figure 2 passes through the line 4, 4 Figure 4 shewing the various passages
between the boiler the infusing vessels and the container and means for con-
trolling them as hereinafter described. Figure 7 shews the boiler and adjuncts
connected therewith, these parts being conveniently arranged below the counter
but they may all be in any other convenient position.
The two infusing vessels A A¹ are supported in brackets B projecting from a
column C which carries a container D into which the infusion of coffee, tea, or
other matter after being made in either of the infusers A A' is passed. This con-
tainer 1) is preferably screwed onto the column Cat & so that it can be readily
removed for cleaning. The passages which afford communication between the
boiler and either of the infusers A A' and between the infusers A A' and the
container D are governed by two cocks E as hereinafter described.
The boiling water is forced from the boiler by the pressure of the steam therein
up the pipe a which leads by passages in the column C and passages in the
brackets B and by a pipe to the upper part of each infuser into which it is
discharged into and through a sieve or perforated box F secured to the upper part
of the infuser. Communication between the passages a¹ and a² is established by
the passages a through each of the cocks E.
Each infuser A A is made in two parts the upper part being hinged at b to
the bracket B and secured by a catch engaging with an eye on the bracket B,
a passage being provided at 62 to establish communication between the passages a
and the pipe a³. The coffee, tea, or other matter from which the infusion is to

page_text: be made is placed in the lower part of the infusers, a porous material being
secured at bottom by a ring, or grid 63 to prevent the ground coffee or the like,
from getting in the passages.
After either of the infusers becomes full of liquid the overflow passes through
the sieve and by a pipe c (see Figure 2) arranged by the side of the pipe
and by a passage in the bracket B through the passage 2 in the cock E and
flows out of a pipe which thus indicates that the infuser is full, the strainer pre-
venting fur, or other matter likely to clog, or contaminate the passages from
passing thereinto.
The cock E is then turned from the position shewn at the right hand side of
Figures 5 and 6 so as to cut off the supply of boiling water to the infuser and the
overflow and so as to cause the passage in the cock E to establish communica-
tion (as shewn at the left hand of Figure 5) between the passage and a passage c
leading into the interior of the column which is in connection with the steam
space of the boiler by a pipe J. Steam then passes by the passages J c c² c¹ and c
to the top of the infuser and exerts pressure upon the surface of
the infusion therein. When either of the cocks E is in this position
another passage d therein establishes communication between the infuser A or A¹
as the case may be, and the container D, the passage d connecting a passage d'
in the bracket (into which an opening at the bottom of the infuser opens) and
another passage d² in a bridge between the two casings of the cocks E. A tube g
leads from this passage to the upper part of the container and is fitted with a
spreading device at . When therefore either of the cocks E is in the position
described the steam pressure acting on the surface of the infusion in the infuser
will force it therefrom into the container D) from which it can be drawn by the
tap II on the pipe h. The tube g is surrounded by another tube g² (closed at top)
into which steam is admitted from the steam space in the column C to keep the
infusion hot and in proper condition. A vent pipe g leads from the upper part
of the space within the tube g² to a tap g (see Figures 2 and 1) to enable the air
to escape from the said space. g is a vent at the top of the container D) to allow
air and steam to escape. I is a tap to enable boiling water to be drawn directly
from the boiler when required the said water rising through a pipe passing
through the steam pipe J. A gauge K is provided to enable the amount of in-
fusion in the container to be ascertained.
When it is desirable to infuse less than a full charge in either of the infusers
say a quarter or half the charge small cocks are provided in the infuser so
that when open they will indicate when the liquid has reached the required level.
Cocks L are also provided in the infusers to enable the liquid to be drawn off
directly without first being passed into the container and also to allow the steam
to escape before the infuser is opened after the infusion has been passed therefrom
into the container. Referring to Figure 7 the boiler M is shewn as being heated
by a ring of gas burners N the supply of gas to which is controlled by an auto-
matic device shewn at 1'. In this a valve 2 is caused to close more or less on to
its seat in the gas passages by the steam pressure from the boiler entering by
a pipe in and acting on a flexible diaphragm n and so regulate the quantity of
gas supplied according to the steam pressure in the boiler. A second diaph-
ragm is provided between which and the diaphragm is a distance piece ³so
as to form a space between the two diaphragms which space is in communication
with the atmosphere. By this means should the diaphragm be ruptured by
excess pressure or wear the steam will escape without passing into the gas pas-
sages. The spring p³ acts to normally open the valve the sensitiveness of which
can be regulated by a screw p³.
A float Q is provided to automatically regulate the supply of water to the
boiler the float being supported in a casing Q outside the boiler and at any
desired distance therefrom and in communication at top and bottom with the
boiler by pipes q q¹ so that the float will rise or fall according to the level of the
water in the boiler. The float is provided with a valve which when the float

page_text: rises, scats itself against a seating around the water exit from the supply
pipe R and so prevents any further supply of water to the boiler until the level
again falls. T is a cock provided with passages to simultaneously control both
the water and gas supply through the passages R and s.
Although we have shewn two infusing vessels it is to be understood that
either one or two may be used but two is generally preferable as the infusions
may be made in them alternately to maintain a continuous supply.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. An apparatus for making and dispensing infusions consisting of the arrange-
ment and combination of parts substantially as hereinbefore described and illus-
trated in the accompanying drawings.
2. In apparatus for making and dispensing infusions separate passages leading
from the boiler to the infusing vessel or vessels and from the infusing vessel
or vessels to the container and means for controlling them substantially as herein-
before described and illustrated by the accompanying drawings.
3. In apparatus for making and dispensing infusions the combination with a
boiler and an infusing vessel or vessels and a passage or passages between the
boiler and the infusing vessel or vessels and a strainer situated in the upper part
of the said infusing vessel or vessels above a passage leading into the container
substantially as hereinbefore described and illustrated in the accompanying
drawings.
4. In apparatus for making and dispensing infusions the combination with
the boiler of a casing outside the boiler and in communication with the boiler at
top and bottom and provided with a valve and float to regulate the water supply
substantially as and for the purpose herein before described.
5. In apparatus for making and dispensing infusions the combination of an
infusing vessel or vessels and a container and boiler with separate passages lead-
ing from the boiler to the infusing vessel or vessels and from the infusing vessel
or vessels to the container and means for controlling the said passages a strainer
into which the passage from the boiler opens and situated above the passage from
the infusing vessel or vessels to the container and a casing outside the boiler and
in communication therewith at top and bottom and containing a float and a valve
for regulating the inlet of water all substantially as herein before described.
