"IMPROVEMENTS IN APPARATUS FOR OBTAINING EXTRACTS OR INFUSIONS FROM
TEA, COFFEE, AND OTHER SUBSTANCES, PREPARING AERATED DRINKS, MIXING
PAINTS, AND FOR OTHER PURPOSES."
The Invention has for its object improvements in apparatus for obtaining
extracts or infusions from tea, coffee, and other substances, preparing aerated drinks,
mixing paints, and for other purposes.
The apparatus consists of an inner and an outer vessel of any convenient
shape.
The outer vessel is provided with an opening in the upper part through which
the water or other liquid is supplied thereto, and with a tap at the lower part
thereof or with a spout by which the contents may be drawn or poured off
therefrom.
The inner vessel is supported at a short distance from the bottom of the outer
vessel, and is of such proportions as to leave a space around the same in order
that it may be completely immersed in or surrounded by the water or other
liquid contained in the outer vessel.
In the interior of the inner vessel is mounted a stirrer or agitator which is
capable of being rotated by a wheel, knob, or handle at the top of the cover.
The inner vessel may be formed of wire-work or of perforated metal or other
material, and it may be lined or covered with any suitable permeable fabric or
material, the meshes of the wire-work, the perforations of the metal or other
material, and the permeability of the living or covering fabric or material being of

page_text: such a character as to permit of the liquid in the outer vessel coming freely into
contact with the contents of the inner vessel and yet prevent any of the solid
substances passing out therefrom.
The inner vessel is formed with capability of being readily opened and closed,
and it is by preference entirely removeable from the outer vessel for filling, emptying,
and cleaning the same. The lower part of such inner vessel may be supported by
a foot or other support from the bottom of the outer vessel, in which case the
cover and agitator would be carried by the cover of the outer vessel, or it may be
entirely supported by the cover of the outer vessel, so as to be inserted into and
removed from the latter by the act of applying and removing the cover thereof.
Other modes however of mounting the inner vessel may be employed provided
it can be readily opened, closed, and cleaned, and the agitator or mixer can be
operated in the manner described.
The inner vessel or its cover is connected with the cover of the outer vessel by
a tube or by other supports, within or between-which the spindlo for operating
the mixer or agitator passes.

The Invention has for its object improvements in apparatus for obtaining
extracts or infusions from tea, coffee, and other substances, preparing aerated
drinks, mixing paints, and for other purposes.
The apparatus consists of an inner and an outer vessel of any convenient shape.
The outer vessel is provided with an opening in the upper part through which the
water or other liquid is supplied thereto, and with a tap at the lower part thereof
or with a spout by which the contents may be drawn or poured off therefrom.
The inner vessel is supported at a short distance from the bottom of the outer
vessel, and is of such proportions as to leave a space around the same in order
that it may be completely immersed in or surrounded by the water or other liquid
contained in the outer vessel.
In the interior of the inner vessel is mounted a stirrer or agitator which is
capable of being rotated by a wheel, knob, or handle at the top of the cover.
The inner vessel may be formed of wire work or of porforated metal or other
material, and it may be lined or covered with any suitable permeable fabric or
material, the meshes of the wirework, the perforations of the metal or other
material, and the permeability of the lining or covering fabric or material being
of such a character as to permit of the liquid in the outer vessel coming freely
into contact with the contents of the inner vessel, and yet prevent any of the
solid substances passing out therefrom.
The inner vessel is formed with capability of being readily opened and closed,
and it is by preference entirely removeable from the outer vessel for filling, emptying,
and cleaning the same. The lower part of such inner vessel may be supported by
a foot or other support from the bottom of the outer vessel, in which case the cover
and agitator would be carried by the cover of the outer vessel, or it may be
entirely supported by the cover of the outer vessel so as to be inserted into and
removed from the latter by the act of applying and removing the cover thereof.
Other modes however of mounting the inner vessel may be employed provided
it can be readily opened, closed, and cleaned, and the agitator or mixer can be
operated in the manner described.
The inner vessel or its cover is connected with the cover of the outer vessel by a
tube or by other supports, within or between which the spindle for operating the
mixer or agitator passes.
And in order that my said Invention may be more clearly understood and
readily carried into effect, I will proceed aided by the accompanying Drawings
more fully to describe the same.

is the body or outer vessel of the apparatus, and b is the inner vessel.
The outer vessel is provided with an opening a¹ in the upper part through
which water or other liquid is supplied thereto, and with a tap or spout a² at
the lower part thereof by which the contents may be drawn or poured off
therefrom.
The inner vessel b is supported at a short distance from the bottom of the outer
vessel a, and is of such proportions as to leave a space around the same in order
that it may be completely immersed in or surrounded by the water or other liquid
contained in the outer vessel a.
In the interior of the inner vessel b is mounted a stirrer or agitator c, which
is capable of being rotated by a wheel, knob, or handle c' at the top of the
cover d.
The inner vessel 6 may be formed of wire work or of perforated metal or other
material, and it may be lined or covered with any suitable permeable fabric or
inaterial, the meshes of the wirework, the perforations of the metal or other
material, and the permeability of the lining or covering fabric or material being
of such a character as to permit of the liquid in the outer vessel coming freely into
contact with the contents of the inner vessel, and yet prevent any of the solid
substances passing out therefrom.
The inner vessel 6 is formed with capability of being readily opened and closed,
and it is by preference entirely removeable from the outer vessel a for filling,
emptying, and cleaning the same.
The lower part b-of-such inner vessel b may, as represented at Figure 3, bo
supported by a foot or other support e from the bottom of the outer vessel a, in
which case the cover b² and agitator or stirrer c would be carried by the cover d
of the outer vessel a, the two parts of such inner vessel b being fitted together so
as to securely retain therein the material or materials under treatment.
Or the inner vessel b may be entirely supported by the cover d of the outer
vessel a, as represented at Figures 1, 2, 8, 9, and 10, so as to be inserted into and
removed from such outer vessel a by the act of applying and removing the cover
thereof.
The inner vessel 6 or its cover 6° is connected with the cover d of the outer
vessel a by a tube for by other supports, within or between which the spindle c*
of the mixer or agitator passes.
In the arrangement represented at Figures 4, 5, 6, and 7, the inner vessel b is
shown to be supported by a cross bar c³ resting in suitable recesses formed in the
neck or opening a' of the outer vessel, and in such case the upper end of tho
spindle c, and the lower end of the knob or handle c¹, are formed or provided
with clutch surfaces to enable motion to be communicated when desired from tho
knob or handle c¹ to the agitator or stirrer c, and yet permit the cover d to be
hinged to the outer vessel a as usual, such arrangement permitting the inner vessel b
to be entirely removed from the outer vessel a without necessarily removing the
cover d therewith.
In the arrangements represented at Figures 1, 8, 9, 10, 11, 12, 13, and 14, the
upper part 6 of the inner vessel b is provided with a flange 63 formed with
openings b', and the lower part b6 of such inner vessel b is provided with a flange b
formed with catches 66, which, when passed through the openings 6* in the flange b³
and then partly turned round, hold the two parts b', 62, of the inner vessel b closely
together.
In the arrangements represented at Figures 2 and 4, the two parts 61, 62, of the
inner vessel b are hinged together at 67, and are provided with a fastening at 68 to
enable the same to be opened and closed as required.
The apparatus represented at Figure 8 for preparing ‘aerated waters has an air

page_text: tight cover capable of being firmly fixed in position and removed when required,
and such cover is provided with a safety valve g.
The apparatus represented at Figure 10 being intended for the infusion of
drugs and chemicals, the outer vessel a is preferably made of pottery.
In the arrangement, represented at Figure 9, for the mixing of paints, the wheel c'
is shown to be rotated by a wheel h¹ fixed to a shaft h, which is capable of being
rotated by a handle h², and I have also shown the spindle c² of the stirrer or
agitator c extended below the bottom of the inner vessel b, and fitted with a stirrer
or agitator c working in the fluid contained in the outer vessel a in order to
ensure an intimate mixture of all the ingredients used.
When employing apparatus of large dimensions steam or other power may be
employed to work the stirrer or agitator when such is required, and if desired a
pump may be connected with the apparatus to draw off the contents thereof for
bottling or otherwise.
I would here remark that other modes than those herein shown and described
of mounting the inner vessel b may be employed, provided it can be readily
opened, closed, and cleaned, and the agitator or mixer c can be operated in the
manner described.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect, 1 would have it understood that I do not claim the
employment of an inner vessel for containing the solid materials under treatment
separately considered, nor do I clain the employment of a stirror or agitator when
such does not work within the said inner vessel, but what I do claim is the
combination with an outer vessel of an inner vessel provided with a stirrer or
agitator, mounted and operated in manner substantially as herein shown and
described and for the purpose stated.
In witness whereof, I, the said William John Clapp, have hereunto set my
band and seal, this Seventeenth day of January, in the year of our Lord
0.
