Improvements in Stoke Holds.
I, DAVID WILLIAMS, of Reefton, in the Colony of New Zealand, Engineer,
do hereby declare the nature of this invention to be as follows:-
The objects of my invention are to provide a convenient stoke hold more
especially applicable to steam ships and which can be maintained at a reduced
temperature by simple means such as by a circulation of sea or fresh water or other
fluids, cooled air, or fluids artificially cooled.
I attain these objects by constructing the stoke hold in the form of a chamber
the walls of which are of metal plates and within this chamber I construct
another and similar chamber but smaller in size so that one chamber is fixed
within the other leaving a water tight space between them in which cool fluids may
circulate.
I have therefore a stoke hold around which a circulation of cooling fluid can be
circulated thus maintaining its walls at a reduced temperature. In the side facing
the furnaces I form orifices through which stoking can be conveniently performed
and I also construct orifices through which the connection for the gauge glasses,
gauge cocks, pressure gauges, or other fittings may pass so that the whole of the
said fittings may be within the cooled chamber.
In ordinary climates I circulate sea water around the stoke hold by a com-
munication to the sea placed (by preference) in the bows of the vessel below the
water line and making its exit at any convenient place, but it is evident that I may
use either fresh or sea water and make use of a pump or other mechanical means to
circulate the fluid. In some cases I propose to refrigerate the fluid more especially
in vessels where refrigerating machinery is made use of or I can make use of the
water used in the process of refrigeration.
I prefer to regulate the circulation of the fluid by baffle or guide plates so that
a uniform temperature may be produced. In new vessels the improved stoke hold
may be erected in the course of the construction of the vessel but for vessels already
made I propose to make them in sections and put them together.
The air for combustion in the furnaces may be either admitted directly into the
stoke hold through the usual cowls used for the purpose or circulated around the
outside of the chamber before admission.

COMPLETE SPECIFICATION.
Improvements in Stoke Holds.
I, DAVID WILLIAMS, of Reefton, in the Colony of New Zealand, Engineer,
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, that is to say :-
The objects of my invention are to provide a convenient stoke-hold more
especially applicable to steam ships and which can be maintained at a reduced
temperature by simple means such as by a circulation of sea or fresh water or other
fluids, cooled air, or fluids artificially cooled.

page_text: I attain these objects by constructing the stoke hold in the form of a chamber
the walls of which are of metal plates and within this chamber I construct
another and similar chamber but smaller in size so that one chamber is fixed
within the other leaving a water-tight space between them in which cool fluids may
circulate.
•
I have therefore a stoke hold around which a circulation of cooling fluid can be
circulated thus maintaining the walls at a reduced temperature. In the side facing
the furnaces I form orifices through which stoking can be conveniently performed
and I also construct orifices through which the connection for the gauge glasses,
gauge cocks, pressure gauges, or other fittings may pass, so that the whole of the
said fittings may be within the cooled chamber.
In ordinary climates I circulate sea water around the stoke hold by a com-
munication to the sea placed by preference in the bows of the vessel below the
water line and making its exit at any convenient place, but it is evident that I may
use either fresh or sea water and make use of a pump or other mechanical means to
circulate the fluid. In some cases I propose to refrigerate the fluid more especially
in vessels where refrigerating machinery is made use of or I can make use of the
water used in the process of refrigeration.

a uniform temperature may be produced. In new vessels the improved stoke hold
may be erected in the course of the construction of the vessel but for vessels already
made I propose to make them in sections and put them together.
The air for combustion in the furnaces may be either admitted directly into the
stoke hold through the usual cowls used for the purpose or circulated around the
outside of the chamber before admission.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved stoke holds having double walls the space between which is kept
cool by the circulation of water or other fluid, substantially as described.
