PROVISIONAL SPECIFICATION.
An Appliance for Making Infusions or Extracts of Vegetable or
other Matters.
I FRANCIS THOMAS BOND M.D. of Llanthony House Gloucester do hereby
declare the nature of this invention to be as follows:-
For the purposes of this invention I construct a cylindrical metallic vessel of any
convenient size, by taking a hollow metallic cylinder and adapting to one end of it,
by a water-tight joint, a metallic pipe open at the one end and by the attached
end communicating with the interior of the cylinder. I then adapt to the free end
of the cylinder a loose rim with a circular plate attached thereto, so as to form a
lid or cover.
The flat part of the cover I perforate with small holes; or I may
use instead thereof a piece of metallic gauze, so as to act as a strainer. I also fix
transversely in the neck of the cylinder, where it is connected with the pipe, a
diaphragm of metallic gauze for a similar purpose.
To use the vessel thus constructed for purposes of infusion I put the material to
be infused into the interior of the vessel and, after affixing the cover, I immerse it
into the liquid to be used for making the infusion or extract. The vessel is then to
be raised and lowered successively in the liquid so as to cause a flux and reflux of
the liquid through it so long as may be necessary to obtain the required result.
The rapidity of the process may be much increased by attaching to the open end
of the pipe an elastic ball, bottle or capsule, or a cylinder with a piston, by the aid
of which the infusing liquid can be rapidly pumped backward and forward through
the vessel and its contents, and a more expeditious result obtained than is obtainable
by simply raising and lowering the vessel in the liquid.

An Appliance for Making Infusions or Extracts of Vegetable or
other Matters.
I FRANCIS THOMAS BOND of Llanthony House in the City of Gloucester,
Doctor of Medicine, 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 :-
For the purposes of this invention I construct a cylindrical vessel, preferably of
metal, and of any convenient size, by taking a hollow cylinder and adapting to one
end of it a pipe, open at one end and attached by the other in a water-tight manner
to one end of the cylinder. I then adapt to the other end of the cylinder a loose
rim, with a circular plate attached thereto, so as to form a lid or cover. The flat
part of the cover I perforate with small holes; or I may use instead thereof a
piece of metallic gauze, so as to act as a strainer. I also fix transversely in the
neck of the cylinder, or at any convenient part in the body thereof, a diaphragm of
metallic gauze for a similar purpose.
In the accompanying drawings
Fig. 1 represents a longitudinal section of my appliance, in which A¹ is the body
of the cylinder, B is the pipe or tubular portion thereof; C is the lid or cover, the
flat part of which (only shown in the drawing in section) is to be perforated with
small holes, so as to allow of the ingress of the infusing liquid and to prevent
egress of the material to be infused. A diaphragm of a perforated metallic plate,

page_text: or a piece of wire gauze, is to be placed at D in the neck of the vessel, or at some
other convenient place, as at E, to prevent the material to be infused, A, from
escaping by the tubular aperture B.
Although I prefer to construct the appliance of metal, for the sake of stability,
I may also make it of glass or earthenware; and in that case I prefer to use a cork
with a tubular hole in it, to the inner end of which a piece of metallic gauze is
adapted, instead of a perforated lid.
Fig. 2 is a representation in section of a vessel constructed of glass or metal in
which the letters indicate parts corresponding to those in Fig. 1, except that
C represents the perforated cork stopper, and in which F represents au elastic
capsule, attached to the tubular portion of the cylinder.
Fig. 3 is a longitudinal section of a modification of my appliance in which
G represents a cylindrical elongation of the neck of the appliance, in which a
piston H is made to work so as to draw the infusing liquid into the vessel when the
piston is drawn towards the neck of the vessel and to force it back through the
material to be infused and through the apertures in C when the piston is again
forced inwards. In other respects the letters in Fig. 3 have the same interpretation
as in Figs. 1 and 2.
To use the vessel thus constructed for purposes of infusion I put the material to
be infused into the interior of the vessel and after affixing the cover or inserting
the perforated stopper, I immerse it in the liquid to be used for making the infusion
or extract. The vessel is then to be raised or lowered successively in the liquid, if
it be constructed as shown in Fig. 1, so as to cause a flux and reflux of the liquid
through the material to be infused, so long as may be necessary to produce the
desired result. By adapting an elastic capsule to the neck of the cylinder, as
shown in Fig. 2, or a pistou as shown in Fig. 3, the infusing liquid can be more
rapidly pumped backward and forward through the material to be infused and the
desired result more expeditiously obtained.
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
The use of a cylindrical vessel, of such a size that it can be employed con-
veniently by hand, for the purpose of making infusions or extracts of vegetable or
other matters by forcing the liquid to be infused through the material contained in
the body of the vessel substantially in the manner hereinbefore described and
illustrated in the drawings hereto attached, either by alternately lifting and
depressing the vessel in the liquid to be infused or by more forcibly producing the
same result by means of a pumping action through the agency of an elastic
capsule attached to the upper end of the vessel or of a piston working in the upper
part of the cylinder through the tubular part thereof.
Dated this 8th day of August 1893.
