PROVISIONAL SPECIFICATION.
Improved Means and Apparatus for Rapidly Cooling and Congealing
Liquids or Semi-liquids.
I JAMES OSBORN SPONG of 226 High Holborn, London, Domestic Appliances
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention has for object cooling and congealing liquids and semi-liquids in
a tube or casing for the manufacture of edible ices, the tube or casing being
provided with a perforated or loosely fitting plunger operable by a handle for
disturbing the atoms of the liquid or semi-liquids during the process of cooling
and congealing when such tube or casing is immersed in a vessel containing the
usual freezing mixture.
The tube or casing is provided with a removable plug or stopper at one end and
with a stuffing box or liquid tight gland at the other through which the plunger
rod can be worked. I prefer to fit a handle to the tube or casing covered with
felt or other non-absorbent to enable the tube or casing to be handled so that
after it is charged with, say, cream, or a mixture, and the plug or stopper inserted
it can be wriggled into a pail or vessel of ice and salt or other freezing agent
and the plunger moved up and down when desired to separate and recombine the
atoms for an equal action of the outer cold upon the contents.
If several of such tubes or casings be used for the same pail or vessel a
succession of congealed bodies in stick shape can be obtained on the removal of the
plugs, and a push action on the plungers.
Dated this 7th day of March 1903.

COMPLETE SPECIFICATION.
Improved Means and Apparatus for Rapidly Cooling and-Congealing
Liquids or Semi-liquids.
I, JAMES OSBORN SPONG, of 226 High Holborn, London, Domestic Appliances
Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascer
tained in and by the following statement :-
This invention relates to certain construction or arrangement of apparatus, in
or by which edible and other ices can be expeditiously prepared in small quantities
for table, and also for medical purposes.
The apparatus consists of a tube of regular or irregular shape, within which the
cream, water, or other media can be retained by a stopper, or end cover for the
insertion of the tube into a pail, or other vessel containing a freezing mixture,
such as chemicals which are well known, or the ordinary salt, and small pieces of
broken ice can be used as the freezing mixture.
The cream, or other liquid or semi-liquid body is disturbed or churned by a
loose fitting piston within the tube in order that the coldness of the mixture in
the pail can be imparted to the substance as it becomes congealed, said piston
Co

page_text: being used to expel the frozen substance after the stopper or end cover is
removed.
It is well known that edible ices at present produced in hotels, and at other
public resorts, as well as those prepared for families, are mostly of such a
character that the outer surface is more hard by crystallization than the interior,
and in consequence it has to be exposed for a time for the crystallization to
disappear, so that the congealed piece may be of uniform consistency and tem-
perature, and in the proper condition for consumption.
By my invention, sticks and other moulded forms of edible ices can be rapidly
made of uniform temperature and softness for immediate use and made only at the
time required for consumption.
The construction of apparatus will be clearly understood from the annexed
drawings.
Figure 1 section of regular shaped tube.
Figure 2 elevation of same.
Figure 3 section of mould for forming edible ices, after the style of blanc-manges,
ready to be placed upon a table.
Figure 4 is an underside view of the mould showing the loose fitting piston with
different shaped holes to enable it to pass through, the substance being frozen, and
for ensuring the coldness of the surrounding mixture being imparted to the contents
of the mould.
Figure 5 represents a vessel with one of my tubes within it, and with the parts
grasped by the hands of an operator during the freezing operation.
Figure 6 indicates the apparatus as removed from the vessel, and the frozen
contents being forced out of the tube by pressure on the plunger.
To enable my apparatus to be manipulated, I have an elongation of the tube,
and cover it with felt, wood, or other material as a hand bold, the knob on the
piston rod serving for the other hand to move the piston up and down, and also for
forcing the frozen contents out of the tube.
The same letters of reference apply to all the figures.
A is the tube. B stuffing box. C piston. D rod. E knob thereon. Felongation
on handle of tube A covered with felt, wood, or other material G. H stopper, or
end cover.
"
To use my invention, I, after removing the stopper, or cover H, invert the
tube A, and fill it with, say, cream for making cream ice, the stopper H is placed
in position, and the tube A immersed in the freezing mixture, the plunger C after,
say, one minute, is drawn up and down to agitate the cream while coagulating, the
plunger being then drawn up, and left in that condition for the cream to "
sett,'
the tube A, when removed from the freezing mixture, is dipped in water, the metal
of the tube being thereby raised in temperature to relieve the ice from the inner
side of the tube ready, when the stopper is removed, for the plunger to push the
stick, or moulded form of ice out on to a plate.
Where quantities of ices are required, a number of tubes can be arranged in the
same freezer pail, and be filled, and emptied in succession.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The apparatus shown on the annexed drawings in or by which cream, or other
agent can be formed solid by coagulation, and in small quantities for the making of
edible, and other ices in the manner described.
2. The hereinbefore described process for making edible and other ices in small
quantities in a tube A, or its equivalent provided with a loose fitting plunger C
having a rod D passing through a stuffing box B and hollow handle F covered with
felt G, or other non-conductor of heat, said tube or its equivalent being provided
with a stopper, or end cover H, as set forth.

page_text: 3. The apparatus constructed and arranged substantially as shown in the annexed
drawings, and manipulated substantially in the manner described for rapidly
cooling and congealing liquids or semi-liquids, as set forth.
