Complete Specification Left. 17th July. 1893-Accepted. 19th Aug. 1893
PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for the
Manufacture of Ice.
We, ARTHUR THOMPSON, FREDERICK WILLIAM THOMPSON and HERBERT
THOMPSON all of Luddenden near Halifax in the County of York Engineers
do hereby declare the nature of this invention to be as follows:-
The object of our invention is to more economically mould blocks of ice so as to
be without air spaces and clear of sediment.
We construct our moulds with the freezing plate at the top so freezing from the
top in the natural manner and dispense with the numerous agitators now employed,
the sediment settles by gravitation to the bottom of the mould, and is carried off
by the unfrozen water. If necessary a gentle stream of water may be passed
through the mould during the freezing operation.
A series of baffle plates may be used to effect the equal distribution of the
freezing liquor or brine.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for the
Manufacture of Ice.
We, ARTHUR THOMPSON, FREDERICK WILLIAM THOMPSON and HERBERT
THOMPSON all of Luddenden near Halifax in the County of York, Engineers, 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 our invention is to more economically mould blocks of ice so as to
be without air spaces and clear of sediment.
We construct our moulds with the freezing plate at the top, so freezing from the
top in a natural manner, and dispense with the numerous agitators now employed,
the sediment settles by gravitation, to the bottom of the mould and is carried off
by the unfrozen water. If necessary a gentle stream of water may be passed
through the mould during the freezing operation.
A series of baffle plates in the freezing chamber may be used to effect the equal
distribution of the freezing liquor or brine.

Fig. 1. is an end elevation of our apparatus for moulding ice.
Fig. 2. is a section of Fig. 1.
Fig 3 is a plan of inside of ice mould or boa.
A is a watertight mould box made preferably much deeper than is required
to be frozen, B is the freezing plate or cistern containing the brine. The
freezing plate B is placed at the top of the mould box, so that the water freezes
from the top in a natural manner.
C is the door placed at the side of the mould box for facilitating the exit of the
ice block. C' is the pipe forming both water inlet and outlet, the mould a made
taper by means of the pieces marked D or by other similar means, so that the

page_text: block of ice will readily leave the mould and drop down on to the wood crosspieces
marked F.
E is a double feeler or indicator by which it can be ascertained how thick the
ice is frozen, or what unfrozen space is left at the bottom of the mould box during
the operation.
The mould box is filled with water, and the freezing commences from the top,
dispensing with the use of the agitators usually employed, the sediment settles by
gravitation to the bottom of the mould, and is carried off by the unfrozen water.
When the block is frozen a sufficient depth the freezing is stopped and the
mould may be opened, and the block of ice drops on to the cross-pieces F, it is
then drawn out, and the mould box again refilled with water, and the process is
repeated.
By our aforesaid improvements we obtain large blocks of solid clear ice, free
from air bubbles.
Having now fully described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we
-claim is :-
1. Manufacturing blocks of artificial ice, by freezing from the top of the ice
boxes, so getting rid of the sediment and air bubbles, substantially as shown and
.described.
2. Ice boxes A tapered at the sides, constructed with top freezing plates B, side
doors C, as and for the purposes shown and described.
