IMPROVEMENTS RELATING TO THE MANUFACTURE OF ICE AND APPARATUS THEREFOR
Year: 1885

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS RELATING TO THE MANUFACTURE OF ICE
AND APPARATUS THEREFOR" to be as follows:-
This invention relates to the manufacture of ice, and to apparatus therefor.
According to this invention the cooling water necessary for the proper operation
of the ice machine is utilized, through the medium of jet-apparatus, for withdraw-
ing the air from the water to be conveyed to the freezing cells, or contained in the
latter, by reducing the pressure.
In this manner an advantageous utilization of the cooling water is rendered
possible for making crystal-ice, and the employment of complicated apparatus for
withdrawing the air from the water is obviated. The jet-apparatus supplied with
cooling water can be connected either with the receptacles designed for holding the
water to be introduced into the freezing cells, or directly with the freezing cells
already filled with water.
According to the first arrangement two closed receptacles are advantageously
employed from which the freezing cells can be filled alternately through pipes
hereinafter termed outlet pipes provided with cocks, and which can be supplied
through other pipes, hereinafter termed inlet pipes, provided with cocks but
connected with the jet-apparatus by other pipes, hereinafter termed jet-pipes.
The jet-apparatus is fed with cooling water through a delivery-pipe, whilst
another pipe termed the discharge pipe communicates with the condensers of the
ice-machine. In each of the jet-pipes is inserted a three-way cock from which
extend branch pipes, the latter enabling the receptacles to be brought into com-
munication with the atmosphere. When filling the receptacles, the cocks in the
outlet pipes are closed, the cocks in the inlet pipes opened, and the three-way cocks
so placed that the air from the receptacles can escape through the branch pipes, the

page_text: latter permitting at the same time, the filling of the receptacles to be observed.
After the filling of the receptacles the cocks in the inlet and outlet pipes are closed
and the communication between the receptacles and the exhauster is established by
suitably turning the three-way cocks. When the withdrawal of air is completed,
the water contained in the receptacles can be let into the freezing cells after
closing the three-way cocks or placing the same so that communication is estab-
lished between the receptacles and the atmosphere through the branch pipes and
by opening the outlet cocks. The duplication of the receptacles and appurtenances
enables the alternate employment of the same, and accordingly the continuous
operation.
If desired, a single receptacle can be employed or the jet-apparatus can be
connected with more than two receptacles.
If the air is to be drawn directly from the freezing cells, a loose cover is used,
which is provided upon its under side with elastic material such as caoutchouc,
leather or the like, and with a tubular arm which permits the connection of the
cover with the jet-apparatus by means of a tube or hose. The said cover is placed
loosely upon the freezing cell and is held, during the operation of the jet-apparatus,
by suction.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
This invention relates to the manufacture of ice, and to apparatus therefor.
According to this invention the cooling water necessary for the operation of ice
machines, is utilized, through the medium of jet apparatus, for withdrawing the air
from the water to be conveyed to the freezing cells, or contained in the latter, by
reducing the pressure.
In this manner an advantageous utilization of this cooling water is rendered
possible in the manufacture of crystal ice, and the employment of complicated
apparatus for withdrawing the air from the water is rendered unnecessary.
The
jet-apparatus supplied with cooling water can be connected either with the recep-
tacles designed for holding the water to be introduced into the freezing cells, or
directly with the freezing cells already filled with water.
Both arrangements are represented in the accompanying drawing.
As shewn in Figure 1, two closed receptacles e, e¹ are employed from which the
freezing cells are filled alternately through pipes provided with cocks f, f¹. The
said receptacles are supplied with water through pipes provided with cocks g g¹ and
connected with the jet apparatus a by the pipes m and m¹.
The jet apparatus a is supplied with cooling water through a delivery-pipe b
whilst the pipe c communicates with the condensers of the ice-machine. In the
pipes m, m³ are inserted three-way cocks d, & from which extend the branch
pipes h, h¹, the latter enabling the receptacles e¹ to be placed in communication
with the atmosphere. When filling the receptacles, the cocks fand flare closed
and the cocks g, g' opened; and the cocks d, d' are placed so that the air from the
receptacles can escape through the pipes h h¹, the latter permitting at the same
time the filling of the receptacles to be observed.
After the filling of the receptacles the cocks g g¹³, ff¹ are closed and the
communication between the receptacles and the exhauster is established by turning
the cocks dd to the proper positions. When the withdrawal of air is completed,
the water contained in the receptacles can be let into the freezing cells, after
closing the cocks & d, or placing the same so that communication is established
between the receptacles and the atmosphere through the pipes h h³, by opening the
cocks ff¹.
The duplication of the receptacles e e¹ and appurtenances enables the alternate
employment of the same, and accordingly the continuous operation.
If desired a single receptacle e can be employed, or the jet apparatus can be
connected with more than two receptacles.
If the air is to be drawn directly from the freezing cells, a loose cover P.
figure 2 is used, which cover is provided, upon its under side, with elastic material i

page_text: such as caoutchouc, leather or the like and with a tube r which enables the connec-
tion of the cover with the jet-apparatus by means of a pipe or hose. The said cover
is placed loosely upon the freezing cell and is held, during the operation of the jet-
apparatus, by suction.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated
to me by my foreign Correspondent, I'declare that what I claim is
First. The employment of the cooling water used in the operation of ice-
machines, for feeding a water jet apparatus for the withdrawal of the air from
the water used in the production of ice.
Second. The employment of closed receptacles serving to receive the water from
which the ice is made, which receptacles can be placed in communication with the
jet-apparatus and with the freezing cells; or of a loose cover p Figure 2, provided
with a joint-tube and elastic packing material, and which is placed directly upon
the freezing cells filled with water, for the purpose specified.
Dated this 14th day of December 1885.
