Improvements in Ice Cream Freezers and the like.
JEHU BAXTER SCHÄFER, Commercial Agent, 21, Pine Road, Cricklewood, London,
N.W., do hereby declare the nature of this invention to be as follows:-
The following is a detailed description of the above, and the manner of working.
Salt and ice is placed in a long narrow cylinder which is called for reference sake,
No. 1, tapering towards the bottom. Near the top of the cylinder No. 1, on the
outside is a wire ring from which projects three or more wires or a flange. On
the top is placed two lids, not necessarily air tight. A wire handle is fixed in such
a position so as it will clear the two lids and lay flat when not required.
This cylinder No. 1, is now placed in a larger cylinder No. 2, so as there is a
space left between where the custard to be frozen is placed.
Then two lids are placed on cylinder No. 2. This cylinder No. 2 is now placed
in a wire ring which is suspended near the top of a still larger insulated cylinder
No. 3, in such a manner that salt and ice can be put all round, and over the top
of cylinder No. 2, which if required can be completely surrounded by ice and
salt. An insulated lid is then placed on the insulated cylinder No. 3, and the
whole left until it freezes.
In a short time the lid of No. 3 is taken off, and the ice and salt pressed below
the ring in No. 3.
The
The lids of No. 2 are then taken off, and No. 1 cylinder lifted right out.
custard will be frozen immediately round where No. 1 cylinder has been and
round the sides of cylinder No. 2.
In order to get it frozen right through, it is cut off, and worked up and down
by a specially made mixer which is in the shape of a tapering cog wheel, having
a long handle.

JEHU BAXTER SCHÄFER, 21, Pine Road, Cricklewood, London, N.W., Com-
mercial Agent, 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 for improvements in ice cream freezers and the like, has for
its object to provide a freezer that will freeze the ice cream without turning, and
that fresh custard can be added to that already frozen.
In one way of carrying out this invention, the double lined case A is provided
[Price 8d.1

page_text: near the top with a wire ring supported by flanges from the sides. Into this ring
is inserted a cylinder B3 which is meant to contain the custard and the like that
is to be frozen. There is a space thus left between the cylinder B and the inside
or the double lined case. The custard to be frozen is placed in the cylinder B
and in order to make it freeze quicker another cylinder C is filled with ice and salt
and placed in the middle of the custard. 2 lids are now placed on cylinder C and
also 2 lids on cylinder B. Ice and salt is now placed in the space that is left
between the cylinder B and the inside of the double lined case. It is quite possible
to fill the ice and salt in this space and completely surround the cylinder B and
over the top as well, in order to start the ice cream and the like freezing when
the machine is filled up and the lid A' is placed on it is then left for a short time.
The lid A' is then removed. The ice and salt brushed off the cylinder B the lids
taken off and the inside cylinder C taken out. The ice cream and the like is then
mixed up with a suitable knife when it will be uniformly frozen. In order to
Keep on freezing it is only necessary to add fresh custard until the strength in
the ice and salt gets exhausted, or if you add fresh ice and salt you can keep on
freezing continously.
In a modification Fig. 2 it shows another way of suspending the cylinder B
by flanges from the inside of case A and the side of cylinder B which overlap
each other. These two flanges have a hole in each, the lower one having a screw
nut fixed immediately under the hole, so as when in position the screw will go
through the 2 flanges and fasten tight into the nut underneath.
Fig. 3 shows a plan of a double freezer having 2 cylinders supported as in
Fig. 2 so as different kinds of ices and the like can be made at once.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what
I claim is
1. An ice cream freezer or the like provided with 2 movable cylinders.
2. An ice cream freezer or the like having a cylinder suspended in such a
manner that ice and salt can be placed all round, and completely cover the said
cylinder.
3. An ice cream freezer or the like having a cylinder in the middle, which is
suspended in such a manner that ice and salt can be placed all round and over the
top of the said cylinder.
4. An ice cream freezer or the like having cylinders as above each cylinders
having 2 lids.
5. An ice cream freezer or the like the arrangement substantially as described
so as ice cream and the like can be frozen.
6. An ice cream freezer or the like the arrangement substantially as described,
so as, as the ice gets exhausted the middle cylinder can be placed in the partially
frozen custard and refrozen.
7. An ice cream freezer or the like substantially as described in Fig. 1 and Fig. 2
and in the plan of the double freezer.
