1, JOHN MONTGOMERIE, of Virginia Place 361 Dumbarton Road, Partick
Lanarkshire, Baker, do hereby declare the nature of my said invention, to be as
follows:-
This Invention has reference to and comprises a new or improved construction of
portable vessel and its fittings for easily and expeditiously freezing or refrigerating
alimentary substances such as strawberry, venilla, lemon and other ices for table use,
and other liquid eatables, and which will be more suitable for family use and for
confectioners and others, than freezing or refrigerating vessels have been as heretofore
constructed.
According to this invention one simple construction of vessel for carrying my
improvements into practice would consist of a vertical cylindrical or bucket shape,
with a bow folding handle for portably carrying it about, and a removable flat lid on
top. A vertical rotating spindle would be fitted within this vessel working in a deep
steadying footstep or bush bearing at its lower end, and guided through a collar or
bush bearing in the centre of the lid, or frame with feathers, at top through which the
driving end would project and have a handle for rotating it by hand. This vertical
spindle would be fitted with duplex or lower and upper sets of one, two, three, or inore
horizontal projecting rings in galleries concentrically and balanced round the spindle,
to carry the moulds or vertical cylindrical close vessels with removable lids in which
are placed the table ices or substances to be refrigerated or cooled. In the outer vessel
or case is placed the salt and ice or other freezing mixture, and when the vertical
spindle carrying the moulds or vessels is rotated by the land lever above, the substances
within the moulds are refrigerated or cooled in a very short space of time, and can be
easily removed by taking off the lid and lifting the moulds out of their carrying rings
individually as required.
The outer vessel and lid might be made of copper or other metal and tinned on the
inside either cased or lagged on the outside or not to prevent radiation, or made of

page_text: .
wood, while the moulds or vessels for containing the frozen mixtures and their carrying
galleries might be made of brass or other metal all tinned to resist the action of the
salt freezing mixtures.
When these refrigerating vessels were desired to be made of a large size the vertical
rotating spindle may be driven by bevel wheel gearing, either single or double acting,
from a horizontal spindle mounted in bearings on or over the lid or frame. These
improved freezers or refrigerators may also be made in the form of one large central
mould or cylindrical vessel within the outer freezing vessel, such as for cream or
other liquids in larger quantities, this vessel would have a hollow spindle for the
driving solid central spindle to pass up through and rotate the cream vessel, by a
feather or key secured at the lower end of tube. The stationary hollow tube or
frame would project down, from the lid or spindle bush within the cream vessel, and
have a number of blades or stirrers secured to it, which when the central spindle and
cream cylinder were rotated, would agitate and mix the cream or other liquid.

1, JOHN MONTGOMERIE, of Virginia Place, 361 Dumbarton Road, Partick,
Lanarkshire, Baker, do hereby declare the nature of my invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement in writing, reference being had to the accompanying
Sheet of Drawings, and to the letters and figures marked thereon, that is to say :-
This Invention has reference to and comprises a new or improved construction of
portable vessel and its fittings, for easily and expeditiously freezing or refrigerating
alimentary substances such as strawberry, venilla, lemon, and other ices for table use,
and other liquid eatables, and which will be more suitable for family use and for
confectioners and others than freezing or refrigerating vessels have been as heretofore
constructed.
And in order that my said invention and the manner of performing or carrying the
same into effect or practice may be properly understood, I have hereunto appended an
explanatory Sheet of Drawings, in which the same reference letters are used to indicate
corresponding parts in all the figures where shown. Figure 1 is a sectional elevation,
and Figure 2a plan, of a refrigerating or freezing outer vessel A constructed in
accordance with my invention, and in which three vertical removable vessels Care
shown for containing the mixtures or ices to be frozen. Figure 3 is a sectional
elevation, and Figure 4 a plan, of a combined agitating or stirring and refrigerating
vessel A, C, constructed in accordance with my improvements. Figures 5 and 6 are
an elevation and plan respectively, to an enlarged scale, of the fixed agitating frame or
stirrer 1) within the inner vessel C, shown in Figures 3 and 4. And Figure 7 is an
elevation half in section, of the lid of the inner mixing vessel C, shown in Figures 3 to 6,
and showing a journal cap D2 which is fitted round the spindle B, to fill up the space
and guide the spindle when the fixed stirring frame D is removed; while Figure 8 is
a plan view of the journal cap D2 shown in Figure 7.
A
Referring to these Drawings:-According to this invention one simple construction
of vessel for carrying my improvements into practice shown in Figures 1 and 2,
consists of an outer vertical cylindrical or bucket-shaped vessel A, with a bow folding
handle A2 for portably carrying it about, and a removable capped lid A¹ on top.
vertical rotating spindle B is fitted within this vessel A working in a deep steadying
footstep or bush bearing B' in the centre of the lower domed end A", of the outer
vessel A, and guided through a collar or bush bearing Bin the centre of the lid A',
or frame through which the driving end would project, and with feathers B on the
spindle B at the top outside, and on which a handle B³ is fitted for rotating it by hand.
This vertical spindle B is fitted with duplex, or lower and upper sets of one, two,
three, or more horizontal projecting rings in gallery arms & concentrically and
balanced round the spindle B, three being shown in Figures 1 and 2, to carry the
moulds or vertical cylindrical close vessels C, with removable lids C, and which rotate
with the spindle B, and into which the table ices or mixed substances are placed to be
refrigerated or cooled. In the outer vessel or case A, is placed the salt & broken
ice, snow or other freezing mixture, and when the vertical spindle B, carrying the
moulds or vessels C, rotated inside the vessel A, by the hand lever B³ outside, the
substances within the moulds C are refrigerated or cooled in a very short space of
:

page_text: time, and the rotative motion keeps them loose and porous, and prevents them from
freezing into a solid mass; and the vessels or moulds C can be easily removed by
taking off the lid A¹ and lifting the moulds C, out of their carrying rings b, 61,
individually as required, and taking off their lids C".
The outer vessel A and lid A', might be made of copper or other metal, and tinned
on the inside and either cased or lagged on the outside, or not, to prevent radiation,
or made of wood; while the moulds or vessels. C for containing the frozen mixtures
and their carrying galleries b, b¹, might be made of brass or other metal, all tinned or
electro-plated to resist the action of the salt freezing mixtures in the outer vessel A.
When these refrigerating vessels Care desired to be made of a large size, the vertical
rotating spindle B may be driven by bevel wheel gearing (either single or double
acting) from a horizontal spindle mounted in bearings on or over the lid or frame A³,
which could be shifted on end to put either wheel in action and turned by a handle
at the one end. As shown in Figures 3 to 8, these improved freezers or refrigerators
may also be made in the form of one large central cylindrical mixing vessel C, fixed
by a screw at 11 to the lower end of its driving spindle B, within the outer freezing
vessel A, such as for cream or other liquids in larger quantities. This vessel C, would
be rotated by the central spindle B, and handle B³ in a similar manner to that described
in reference to Figure 1; and the rectangular blade fixed stirrer or frame D would
be mounted loose on the inner part of the spindle B, and held stationary from turning
by feathers on its upper bush eye D' fitting into grooves in the bush B of the lid A
of the outer freezing vessel A, the upper end of the spindle B being steadied and
turned within the eye D. When the central spindle B and cream cylinder Care
rotated inside the vessel A, by the handle B3 outside, the stationary frame or stirrer D),
would agitate and mix the cream or other liquid in the cylinder C, working close to
the sides and bottom of the vessel C, and keep the mass from freezing into a solid
block. When the agitator D is desired to be removed, to turn the vessel and the
ices in it without the stationary stirrer, a cap bush D², shown in Figures 7. and 8, is
mounted over the bush C2 of the lid C₁ of the vessel (', to fill up the eye B" in the
onter lid A, and steady and guide the upper part of the spindle B and vessel while
being rotated.
When these vessels are made of large size, as stationary vessels instead of portable,
they might be secured to a basement frame, table, or bench, and turned by pulleys
and bands in place of by the handle B³.
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
First. The construction and use of a freezer or refrigerator, consisting of an outer
vessel containing salt and ice or other freezing mixture, within which is fitted and
rotated one, two, three, or more removable inner vessels containing ices or other
alimentary substances to be frozen, substantially as and for the purposes herein
described, in reference to and shown in Figures 1 and 2 of the accompanying
Drawings.
Second. In freezers or refrigerators, the combination of an outer freezing vessel
within which is fitted and rotated an inner vessel having a fixed agitating frame or
stirrer mounted within it,. for mixing the cream or other alimentary substances to be
frozen, substantially as herein described, in reference to and shown in Figures 3 to 8
of the accompanying Drawings.
