PROVISIONAL SPECIFICATION.
An Improved Combination Cocoa-pot and Agitator for same.
I, CAROLINE MARY BLAGDON of 23 Glen Street, Hawthorn, in the County of
Bourke, Colony of Victoria, Gentlewoman, do hereby declare the nature of this
invention to be as follows:-
-
The object of my invention is to provide a vessel in which the prepared cocoa
can, by a handle and beaters, be instantly agitated.
Hitherto when cocoa has been prepared in a vessel for ordinary use the lighter
constituents only have been suspended in the water, the heavier parts falling to the
bottom. Unless aroused by a spoon, or some other somewhat imperfect device, the
most nutritious parts of the compound there remained.
By the use of my device the liquid whilst in preparation and before being
poured out for use, can be vigorously stirred, thereby assuring both a rapid and
perfectly thorough distribution of the constituents of the beverage before it is
drunk.
My combination consists in a vessel which has on its inside bottom a recess or
bearing hole, into which a spindle is deposited. This spindle carries two or more
beaters which in diameter are almost the same size as the interior of the vessel and
in length are somewhat shorter, a cover fits onto the top of the vessel and through
the centre of this the spindle, with a handle on the top of it is carried. The beaters
may be spirally fitted to the spindle, may be flat with holes through, S, or other
shaped, and may (if need be) be attached to a footstep in lieu of bearing hole in
bottom of vessel.

1, CAROLINE MARY BLAGDON of 23 Glen Street, Hawthorn, in the County
of Bourke, Colony of Victoria, Gentlewoman 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 :-
The objects of my invention are to provide a vessel in which the prepared cocoa,
by a handle and beaters can be instantly agitated before each discharge of its
contents.
Hitherto when cocoa has been prepared in a vessel for domestic table use the
lighter constituents only have been suspended in the outflowing liquid and the
heavier and most nutritious parts have uselessly remained unremoved at the bottom.
Unless aroused by a spoon or other such crude device the most health yielding
portions of the beverage have been wasted. By the use of my device the liquid
not only whilst it is in preparation but also before each discharge can without any

page_text: trouble be vigorously stirred. A perfect assimilation of the constituents of the
compound are thereby assured.
My first combination consists of a metal vessel which may be used either to
contain hot water or to prepare cocoa and the top of it is covered by two shutters
hinged at the circumference and with their meeting edges across the middle. A
lifting knob, with locking arm is attached to one of them and through the middle
of the meeting edges (and therefore in the centre of the vessel) is a hole, half in
each shutter, to admit the spindle of the agitator. This spindle falls into a hole at
the bottom of the vessel and has almost sweeping the same one or more paddles or
agitators secured to it. These agitators or paddles, which may be filled with
perforations, are either parallel to the spindle or arranged spirally as a corkscrew.
At the top of the spindle is a crank handle and beneath it and beneath the meeting
edge of the shutters is a cross or bearing bar the two outside ends of which fall
into suitable recesses in the top edge of the vessel. By unlocking and opening the
shutters the whole of the agitating device may be instantly removed for cleansing
or other purposes.
My second combination consists of an agitating attachment, which is applicable
to any ordinary cocoa or other vessel that may be employed, and into which it may be
placed or from which it may be removed without either time, trouble, or incon-
venience. It consists of a flat round plate (with one side cut away to clear the
vessel handle) which plate is placed over the top of the vessel. In its middle is
a hole through which the agitating spindle passes and is guided. Rivetted or
otherwise attached beneath the said cover are three or more pieces of elastic metal
(in one or more lengths) which not only adjust themselves to the mouth of any
sized vessel but also form the bottom bearing for the spindle. The spiral or plain
agitators aforesaid are attached to the spindle and beneath the said springs.
But in order that my invention may be more clearly understood I will now refer
to the accompanying sheet of drawings which are to be taken as part of this
Specification and read therewith.
Similar letters of reference indicate similar or corresponding parts where they
occur in the several views.
Fig. 1 represents a side view partly in elevation and partly in section of a
cocoa vessel and agitators in which A is the vessel and B and C the shutters
forming the cover, D is the lifting knob by which the cover C is raised, and E the
locking arm for locking the two covers when closed. F is the spindle which is
rotated by the crank handle G (screwed or otherwise fixed to F) and rests at its
bottom in the hole H. I are the agitators which are perforated with holes J, and
are spirally arranged around the spindle F.
Fig. 2 is a plan of Fig. 1 with the shutter B raised and shewing the cross bar K
by which the spindle F is retained in the centre. This cross bar K is let into
slots L.
Fig. 3 is a view partly in elevation and partly in section of my second combination
in which the cover M is composed of one piece of plate and has attached to it
three or more pieces of elastic metal N bent as shewn. These pieces of metal (each
of which may be in one or more lengths) answer the dual purpose of a bottom
guide for the spindle F, and a spring arm O, by which the attachment will centrally
adjust itself to the mouth of any sized vessel. P is a tubular distance piece, by
varying the length of which, the distance of the agitators 1 from the bottom of the
vessel may be regulated.
Fig. 4 represents a plan of Fig. 3 shewing one side cut away as at Q in order to
clear the handle.
Seeing that the agitators have a greater tendency to elevate and distribute the
heavier constituents contained in the cocoa when they are arranged spirally, (as
shewn in the drawings) rather than when they are parallel to the spindle, I
generally prefer to arrange them as shewn. But I find that by holes such as J in
a four armed agitator and with two of the said arms straight and parallel with the
spindle, results equally as good may be obtained. 1 therefore may make the

page_text: agitators plain or spiral or the same alternately whatever the number of paddles or
agitators may be.
On reference to Figure 3 it will be seen that the attachment is perfectly inde-
pendent of the vessel and in order to make it applicable to the necks of any sized
vessel I provide the pieces of elastic metal N with spring arms O. I also provide
a tubular adjusting piece P beneath the handle G which can be increased or
diminished in length and the agitators thus kept off the bottom of shallow vessels.
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 :-
1stly. In vessels for preparing cocoa, the combination of a crank handle G,
driving a spindle F, on which are fixed three or more perforated or unperforated spiral
or straight (or spiral and straight alternately) agitator arms I. as and for the purposes
hereinbefore set forth and as illustrated in Figures 1 and 2 of the drawings.
2ndly. In vessels for preparing cocoa, the combination of a crank handle G,
driving a spindle F resting in a hole H, on the bottom and steadied at its top by a
cross bar K, with its ends sunk into pocket L, on the rim of the vessel onto which
spindle is attached three or more perforated or unperforated spiral or straight (or
spiral and straight alternately) agitators; a cover formed by two shutters B and C
to the latter of which the lifting knob D and locking arm E are attached sub-
stantially as herein before described and as illustrated in Figures 1 and 2.
3rdly. For use in vessels for the preparation of cocoa, the combination of a crank
handle G, turning a spindle F, with three or more perforated or unperforated
spiral or straight (or spiral and straight alternately) agitator arms I, a cover M
with removed side Q to which cover are attached three or more divided or undivided
pieces of elastic metal each bent to form a half bearing for the bottom of the
spindle K and with a spring arm substantially as herein described and as
illustrated in Figures 3 and 4 of the drawings.
4thly. The combination of the whole of the parts set forth upon Figures 1 and 2
and 3 and 4 of the accompanying drawings constituting "An improved combination
cocoa-pot and agitator for same.'
