PROVISIONAL SPECIFICATION.
Improved Construction or Arrangement of Apparatus for Making
Ices, Edible and other.
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, the construction and employment of one or more
tubes with a handle, or handles at or from the upper part, and with a screw valve,
or valves, at, or near the lower part. Each tube has a closed bottom, and the top
is open for the insertion of a perforated or openwork plunger, the rod of which
may have a flanged, or other disc to serve as a cover to the tube to retain the cold
air within it.
The invention thus described is applicable for making frozen sticks, or columns
of substances, or liquid, such as for edible ices, or for plain ice as desired, either
by a freezing mixture composed of salt and ice, or by chemical mixtures when no
ordinary ice is available.
the
The tube or tubes when charged with the substance, or liquid, is immersed in a
jar or pail, and by slight agitation of the contents, a rapid congelation occurs,
air being extracted by motion of the plunger.
When the substance or liquid in the tube is sufficiently "sett," (which can be
ascertained by a pressure on the plunger, or by sight, if the cover or the plunger
be withdrawn), the tube is removed and dipped in a pail of water of a higher
temperature to free the stick, or column from the inner surface of the tube, the
tube is then tilted for the stick or columu to slide out, which it will do on the
bottom valve being opened to let air in under it.
It is not essential that the plunger rod be central therewith, it may be at the
side, so that if the plunger be left at the bottom of the tube, the stick or column
can be lifted by it.'

Improved Construction_or Arrangement of Apparatus for Making
Ices, Edible and other.
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 ascertained in and
by the following statement:-
This invention has for object, the construction and employment of one or more
tubes with a handle or handles at or from the upper part, and with a screw valve
or valves at or near the lower part. Each tube has a closed bottom, and the top
is open for the insertion of a perforated or openwork plunger, the rod of which
may have a flanged or other disc to serve as a cover to the tube to retain the cold
air within it.

page_text: The invention thus described is applicable for making frozen sticks or columns
of substance or liquid, such as for edible ices, or for plain ice, as desired, either by
a freezing mixture composed of salt and ice, or by chemical mixtures when no
ordinary ice is available.
The tube or tubes when charged with the substance or liquid is immersed in a
jar or pail, and by slight agitation of the contents a rapid congelation occurs.
When the substance or liquid in the tube is sufficiently "sett" (which can be
ascertained by a pressure on the plunger, or by sight if the cover or the plunger
be withdrawn), the tube is removed and dipped in a pail of water of a higher
temperature to free the stick or column from the inner surface of the tube, the tube
is then tilted for the stick or column to slide out which it will do on the bottom
valve being opened to let air in under it.
It is not essential that the plunger rod be central therewith, it may be at the
side so that if the plunger be left at the bottom of the tube the stick or column can
be lifted by it.
My invention will be clearly understood by referring to the annexed drawings.
Figure 1 is a section of my apparatus in complete form.
Figure 2 a detached view of the plunger and the closing disc of thimble like
formation.
Figure 3 a separate view of the tube of circular shape.
Figure 4 represents a rectangular shape of tube.
Figure 5 a detached view of the plunger and closing disc for such shape
of tube.
Figure 6 is a plan of the tube and plunger of rectangular shape.
Figure 7 represents another form or shape of tube. with the plunger rod at the
side of the plunger and within a channel or groove shaped in the tube.
Figure 8 indicates a section of a many sided tube in which a plunger of corre-
sponding shape can be operated.
The examples given are intended to prove that I do not limit myself to any
particular form or contour of tube or tubes for the purpose of effecting the object
I have in view and such as I have herein before described.
A is a tube closed at bottom. B handle affixed thereto. C thimble shaped disc
fitting open end of tube A and serving as a guide for the motion of the plunger
rod D, the plunger of which is perforated, or of open worked metal, and has cutting
edges as at E, and fits the tube loosely when moved up and down by the knob F.
G is a perforated projection at the bottom end of the tube A, said perforation
being closable by the screw valve H.
The method of making edible ices by my invention is as follows;-A pail is
prepared with ice and salt, or with a freezing mixture in a well known manner, and
the tube is nearly filled with the liquid or semi-liquid to be frozen or congealed the
plunger is inserted and pushed down within the tube, and the thimble shaped disc
pushed home to enclose the liquid or semi-liquid, the valve at the bottom of the
tube having been previously closed.
The tube thus charged is immersed into the mixture of ice and salt, or of the
freezing mixture as the case may be, and left there a few seconds, the plunger can
now be raised and the amount of congelation ascertained by the touch, this not
only serves to indicate the condition of the contents of the tube but cuts away and
separates the outer crystals globules, or particles, and remixes them, so that the
middle of the partly congealed body can be the more effectually exposed to the
action of the cold which penetrates through the metal of the tube from the contents
of the pail.
The plunger can remain at the upper part, or be again lowered or
forced down the tube until the required amount of freezing has taken place, which
generally occurs in about five minutes (more or less) after this the tube is removed
from the freezing pail and dipped in a pail of water of ordinary temperature for
the particles adhering to the inner wall of the tube to become dislodged by the
slight warmth imparted by the water. On the tube being removed from the pail,
it is wiped, the screw valve loosened to let air into the tube, and the thimble

page_text: shaped disc removed to enable the frozen stick of edible or other body to be-
withdrawn by the plunger, or by turning the tube upside down the stick will slide
out on to a plate or dish set for its reception, the tube being then refilled for the
preparation of another stick, and so on.
With a little practice and ordinary skill, an unlimited supply of edible ices in
stick like form and of different kinds can be maintained during the hottest weather,
by having a number of tubes charged and immersed in the same or in different
pails within ready reach of an attendant such as could be arranged in a tent or
booth at a fancy fair, a bazaar, a race meeting, a school treat, a public or private
dinner party, or other place, or where an assemblage of persons can be temporarily
brought together.
I have described and shown single tubes but they can be arranged in couples, or
in groups with one handle for a series of them.
I wish it to be understood that I make no claim to the invention or use of a tube
under my Patent Rights, nor to the use of a plunger in a tube, but
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 combination of a tube, a perforated plunger, a valve, a thimble shaped.
disc, as an apparatus in or by which sticks of congealed liquid or semi-liquid known
as edible ices can be produced in a simple yet rapid manner, as described.
2. The manufacture and employment of an apparatus, such as is shown on the
annexed drawings, for making edible and other ices in stick like form, as set.
