Improvements in Apparatus for Producing Ice Cream and
the like.
We, GEORGE ALBERT AMOS of 165 Vickerys Chambers Pitt Street Sydney in
the Colony of New South Wales Inventor JOHN MILTON BROWN of Mosman's
near Sydney aforesaid Gentleman and NUMA AUGUSTUS JOUBERT of Hunter's
Hill near Sydney aforesaid Steam Boat Proprietor 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 object of this invention is to provide an apparatus of simple construction
for the instantaneous freezing of liquids or semi-liquids and thereby producing ice
cream and the like.
Hitherto, to freeze cream and the like and produce ice cream, considerable time
and labour are spent.
Now this invention enables cream and the like to be frozen instantly and with
considerable saving in the amount of freezing materials required. But in order
that this invention may be more fully understood reference will now be made to
the accompanying sheet of drawings in which;
Figure 1 is a perspective view of this improved apparatus.
Figure 2 is a longitudinal sectional elevation of this improved apparatus.
A is an oblong box preferably constructed of wood, but may be constructed of
any other suitable material having a concave top B, which is detachable from the
lower part of A. C is a cylinder which may be constructed, of glass, porcelain,
metal or any other suitable material, provided with a large opening D at one end,
the other end having a central projection. The cylinder revolves inside the
apparatus, and is supported by bearings provided in each side of the box A, a
cap E provided with a washer is placed over the opening D. The crank handle F
is so shaped that when placed over the cap E and the wing nut G will securely
clamp the cap E and the crank handle F. This handle may be attached to the
other end of the cylinder if desired the cap E would then be clamped over the
opening D in any suitable manner.
A transfer roller H constructed of glass, wood, or any other suitable material is
supported in oblique bearings in which a small spiral spring is placed in somewhat
the position shewn in Figure 2.
This transfer roller H is provided with parallel grooves or notches I and is so
placed that when the cylinder C revolves the spring bearings will cause the roller H
to press against the cylinder C and revolve in the opposite direction. Another
roller J with smooth surface is supported in bearings similar to those of roller H,
and is placed somewhat in the position shewn in Figure 2, pressing against the
cylinder C.
Above the roller H is placed a device preferably made of metal and vulcanite
but may be made of any other suitable material which is supported upon two
rods K in such a manner that the vulcanite strip L presses against the periphery
of the cylinder C.
A peculiarly constructed tray M is placed beneath the cylinder and rollers, in
the box A. It will be seen on reference to Figure 2 that the bottom of this tray
is sloped from either end to a line immediately below the centre of the transfer
roller H. One side of this tray is slightly covered so that the apparatus may be

page_text: turned on its side without fear of spilling any small quantity of liquid that may be
in the tray.
The opening N in the top of the box A as shewn in Figure 2 is for the
purpose of providing an inlet for the cream or other substance to be frozen.
In the concave top B, a sheet of glass, O is placed in such a position that the
person working the apparatus, without removing the cover B, may observe its
operation.
To operate the apparatus it is necessary. to remove the cap E from the
opening D, in the cylinder C and to fill the said cylinder with pieces of ice and
salt which when charged and the cap E and the handle F secured is placed in its
bearings in the box A. The substance to be frozen such as cream or the like is
poured into the tray M, through the opening N. The handle F on being turned
revolves the cylinder C in the direction shewn by arrows in Figure 2 the transfer
roller H revolving in the opposite direction picks up the substance to he frozen in
the grooves or notches I, and transfers it to the periphery of the cylinder C, it is
then carried round until the roller J is met, this roller acts as a compresser and
spreads the substance to be frozen in a very thin layer on the periphery of the
cylinder C when it becomes instantly frozen. The cylinder C does not at any time
come in contact with the substance placed in the tray M, excepting when transferred
from the roller H.
The vulcanite strip L pressing against the cylinder C acts as a scraper removing
therefrom the substance being treated in a frozen state, which on its removal falls
down the shute P into the receptacle Q.
The end R of the box A is so constructed that it can be opened or lifted up to
permit of the withdrawal of the tray M, and the receptacle Q
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is;
1st. In apparatus for freezing liquids or semiliquids and producing ice cream
and like, the combination and arrangement with a cylinder such as C, a transfer
roller such as H, with grooves or notches such as I and a plain roller such as J
substantially as herein described, explained, and illustrated in the drawings.
2nd. In apparatus for freezing liquids or semiliquids a box such as A having a
cover such as B, with a glass section such as O, an inlet such as N, substantially
as herein described, explained, and illustrated, in the drawings.
3rd. In apparatus for freezing liquids or semiliquids the combination and
arrangement 'th a cylinder such as C, a scraper such as L a shute such as P, a
receptacle, su as Q, substantially as herein described explained and illustrated
and for the purpose set forth.
4th. In apparatus for freezing liquids or semiliquids the combination and
arrangement with a cylinder such as C, rollers such as H and J, having spring
bearings a tray such as M, and a feeding channel or inlet such as N, substantially,
as herein described, explained, and illustrated in the drawings.
5th. The combination and arrangement of the mechanical parts herein described,
explained and illustrated all together forming the improved apparatus for producing
ice cream and the like.
