PROVISIONAL SPECIFICATION,
Improved Apparatus for Percolating and Expressing Tinctures, Fluid
Extracts, or Concentrated Infusions.
I, FRANK TEBBUTT Manufacturing Chemist 52 Huddleston Road Tufnell Park
London N. do hereby declare the nature of this invention to be as follows:-
This Apparatus consists of a Covered Cylinder through which Cover a Screw
resting on a Perforated Plate is inserted for the purpose of keeping the Ingredients
to be operated on pressed tightly during the process, and lastly "by substituting a
Plate not Perforated " for pressing out the remaining Fluid in the Solid Ingredients.
The cylinder is fitted with a False Bottom Perforated resting on studs to raise it from
the Real Bottom. On the outside of the Cylinder is fixed a Pipe running from its
extreme top and terminating at the bottom, where it communicates with the inside of
the Cylinder. The Pipe is for the purpose of admitting the Fluid wherewith to make
the Preparations. The Fluid enters at the bottom, passes through the Perforated
False Bottom & percolates upwards through the Solid Ingredients, and is collected in
the upper part of the Cylinder from whence it is drawn off by means of a Spout fixed
in the side. Iu the Centre of the Bottom of the Cylinder is fixed a Tap by means of
which the last portions of Tincture, Fluid Extract or Concentrated Infusion are
drawn off.

I FRANK TEBBUTT Manufacturing Chemist, 52 Huddleston Road, Tufnell Park,
London, N., 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 statenient :-
This Invention relates to improved apparatus for percolating and expressing
tinctures, fluid extracts, or concentrated infusions whereby such processes are per-
formed in a very perfect manner by upward percolation and with great saving of time,
spirit, and labour, the entire process being completed in one apparatus of very simple
construction and working.

Figure 1 represents a side elevation of an apparatus embodying my invention;
Figure 2 a sectional elevation through the same.
A indicating a cylinder through the cover a of which passes a screw B, resting on
a perforated plate C between which and a perforated false bottom E are placed the
ingredients D to be treated; F is a supply or liquor pipe opening into the cylinder in
the space between the false bottom E and the actual bottom of the cylinder, rising
outside the cylinder to any desired height above it, and terminated by a funnel G ;
His a spout or draw off and I a drain cock; K is a plate being the actual bottom of
the cylinder A, and of sufficient diameter to form a flange k by which the apparatus
may be screwed on to a table or stand; L is a stay for giving rigidity to the pipe F.
The screw B works in the screw threaded bearing band the cover a screws on to
the cylinder A. The pipe F is jointed at f, or in any suitable part, so that the
funnel G may be removed and a flexible or other tube be substituted if desired.

page_text: De working is as follows :-
The cover a is removed from the cylinder A and the perforated plate C also
withdrawn therefrom, the ingredients to be treated (D) are then placed upon the
false bottom E in suitable quantity, the plate C placed thereupon, the cover a
replaced and the screw B brought down upon the plate C. The alcohol or other
fluid wherewith to make the preparation is then introduced into the funnel G, from
whence it passes by the pipe F into the cylinder A, beneath the false bottom E
through which it percolates upwards through the soiid. ingredients and plate C to
the upper part of the cylinder, from whence it passes off by the spout H into any
suitable vessel. At any time during the process the solid ingredients may be sub-
jected to suitable pressure by simply turning the screw B, and when the process
of upward percolation is completed I may place a non-perforated plate upon the
plate C and thereby express a further portion of tincture, fluid or concentrated
infusion from the solid ingredients, drawing it off by opening the tap I.
I may make the vessel A and the plates or diaphragms within it of metal,
porcelain, earthenware or any suitable material, and of any desired shape and
dimensions and I may substitute for the metal pipe F and funnel G a rubber or
other tube leading to any convenient vessel or reservoir above the cylinder. I
may also extend the spout within the cylinder, slightly curving it at that end io
receive a flexible or other tube, and provide the spout on the exterior with a pippet
thereby forming a syphon.
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. Improved apparatus for percolating and expressing tinctures, fluid extracts or
concentrated infusions, consisting of a vessel or chamber having a perforated false
bottom, provided with a screw or press by which the ingredients to be treated may be
compressed between this false bottom and a perforated plate, a pipe or tube leading to
a funnel or reservoir above the percolating vessel or chamber containing the fluid to
be passed through said vessel, a spout or syphon, from which the tincture, fluid
or infusion may pass or be drawn off and a drain cock, substantially as hereinbefore
described.
2. The improved apparatus for percolating and expressing tinctures, fluid extracts
or concentrated infusions herein before described and illustrated upon the accompanying
Sheet of Drawing.
