WILLIAM WHITWORTH NIGHTINGALE, Manager and Secretary of the Southport
Glaciarium and Ice Making Company (Limited) of Southport in the County of
Lancaster. "IMPROVEMENTS IN MEANS OR APPARATUS FOR THE MANUFACTURE
OF BLOCK AND OTHER ICE."
In the manufacture of block Ice it has been usual to place the boxes with the
moulds within them in tiers, one tier arranged above the other and the brine or
freezing mixture is forced with a pump or other suitable forcing means through
the successive tiers and any surplus freezing liquid or medium that did not pass
into the boxes to act on the respective moulds passes up into a vessel or reservoir
overhead to return again to a lower level to be again forced through the
refrigerators and then again to the boxes to act on the moulds by pumping or
otherwise.
According to my improvements I place all the boxes with the moulds on or
about the same level and the brine or refrigerating medium simply flows from one
tank or reservoir to the respective boxes or moulds and the overflow therefrom
after it has passed through the boxes to the moulds returns along an open trough
enclosed only by slight covers to keep out dirt and warmth therefrom to another
tank at a lower level from which it is again passed through the refrigerating
means to be again conducted to the reservoir for supply to the moulds and boxes.
I also apply taps to the supply to each mould so as to afford facility for readily

page_text: shutting off or controlling the supply to any of the moulds when sufficient ico
has been produced therein thereby removing unnecessary pressure from such
moulds.
I also apply fins or dividers in the boxes to control more efficiently the direction
of the water to be frozen in its progress.
I also allow the refrigerating mixture to flow from the mould boxes into the
pipes used to effect surface freezing for surface ice adapted for skating, curling or
Buch like uses.
Thus the surplus power in the freezing munchine is utilized by working the
block ice machinery at the same time and with the same circulation both open
and closed,

WILLIAM WHITWORTH NIGHTINGALE Manager and Secretary of the Southport
Glaciarium and Ice Making Company (Limited) of Southport in the County of
Lancaster IMPROVEMENTS IN MEANS OR APPARATUS FOR THE MANUFACTURE
OF BLOCK AND OTHER ICE'
In the manufacture of block ice it has been usual to place the boxes with tho
moulds within them, in tiers, one tier arranged above the other, and the brine or
freezing mixture is forced with a pump or other suitable forcing means through
these successive tiers and any surplus freezing liquid or medium that did not pass
into the boxes to act on the respective moulds passed up into a vessel or reservoir
overhead, to return again to a lower level to be again forced through the
refrigerators and then again to the boxes to act on the moulds by pumping or
otherwise.
According to my improvements I place all the boxes with the moulds on or
about the same level and the brine or refrigerating medium simply flows from one
tank or reservoir to the respective boxes or moulds and the overflow therefrom
after it has passed through the boxes to the moulds returns along an open trough
enclosed only by slight covers to keep out dirt and warmth therefrom to another
tank at a lower level from which it is again passed through the refrigerating
means to be again conducted to the reservoir for supply to the moulds and boxes.
When employing two or more separate boxes or series of compartments for
moulds, it often happens that the ice becomes formed in the moulds, in one box or
series of compartments for moulds sooner than in another, or others, and I find it
convenient to be able to open one box or series of compartments of moulds without
disturbing the other or others.
For this purpose I provide the passage for the brine from the respective boxes
or compartments for moulds with slides or stop valves capable of boing readily
applied to the passage for the brine from the box or compartment to be opened
previous to letting in the warmer brine for the purpose of loosening the blocks
of ice in the respective moulds of that box or compartment to facilitate the removal
of such blocks.
By these means I am enabled to prevent the mixture of such warm brine with
the cold brine in the main cold brine tank and the consequent injurious increase
of the temperature of the brine in that main tank intended for the manufacture
of ice and I provide an extra passage or passages for the passing away of this
warner brine to a separate small tank provided for the purpose. Taps or valves
are provided to these extra passages to regulate or control the flow through
them.
I also apply taps to the supply to each mould so as to afford facility for readily
shutting off or controlling the supply to any of the moulds, when sufficient
ice has been produced therein thereby removing unnecessary pressure from such
moulds.
I also apply fins or dividers in the boxes to control more efficiently the direction
of the water to be frozen in its progress.
I also allow the refrigerating mixture to flow from the mould boxes into the
pipes used to effect surface freezing for surface icc adapted for skating curling or
such like uses.

page_text: Thus any surplus power in the freezing machine is utilized by working tho
block ico machinery at the same time and with the same circulation, as for the
surfaco icc.
Having thus described my improvements and means which I adopt in carrying
the same into effect I would have it understood that I do not confine myself to
particular incans for carrying the saune into effect But what I do claim is the
arranging or combining parts forming means or apparatus for the manufacture of
block and other ice substantially as described.
In witness whereof 1 the said William Whitworth Nightingale havo
hereunto set my hand and seal this thirteenth day of October One
