Temperature Ice House 30 Sept 1796
Below the Ice
House, room for
a Balneum Conservatory.
The Balneum
a Binn, in which
the Barrels im (immersed
in water)
may be ranged as at
present in a Cellar
[upon wooden stands.]
The depth of the
Binn such, that
the water may cover
the largest Barrels
intended to be
used.
The floor of the Binn may
be sunk more or
less below the floor
on which a man
will stand to get the
a Barrel out of the
Binn.
To save economize
the Cold, the only
entrance into the
Conservatory may
be down from the
Ice House:
-Or the only entrance
into the Ice
-house, up from
the Conservatory
Means of keeping
the Water of the Balneum
at its level
As the Ice from the
Ice-House melts &
drops into it, it will
rise: and for every
Barrel
Barrel taken out
of it, it will sink.
The entrance should
be through the Conservatory
up into
the Ice House::because
a deficiency
in the cold of the
Ice House can not
be supplied: whereas
so long as there
is cold enough in
the Ice House, any
deficiency of cold
in the Conservatory
may be supplied
from thence: and
heat may be let
in there if wanted
without
The Receptacle
for the Ice being
conical pyramial
cuneiform
or Maximise less
at bottom than at
top, where is it less
a part of the height
of the Conservatory
may be taken out
of the Ice House
This part will
afford room for
a man to mount
up byto a broad ladder
to a door opening
laterally from the
Conservatory below
into the Ice House
above.
The Ice House
may be lighted from
above by a Skylight
pane or two
which may be in
the manner of a
2ble or even a 3ble
window: with a
flap over the outside
pane, by
way of a shutter,
to be opened
only when light is wanted
—
The BalneumWater
Conservatory would
answer the purpose
of a drain to the
Ice House, till the
Water got above
the highest temperature
meant to be
kept up.
It might then
be kept at that
temperature by a
piece of Ice from
time to time thrown
from the Ice House
The accession of
Water from the Ice
Reservoir would
be so gradual, even
in the hottest weather
that no
drain would be
necessary. A pint
of Water in a day
taken out of the
Water Conservatory
would probably more
that counterbalance
it. This quantity
would be of use in
the way of watering
to the ground: after
standing to acquire the temperature.
Whatever space
was not occupied
by the Water, might
be filled with
Stilons and used as
a Dry Conservatory,
excepting the Space
necessary for passage
and for doing the
work in.
The Water Conservatory
might
consist if different
Binns or Cisterns
wooden, kept up to
so many different
degrees of temperature.
The temperature
might be kept
up by periodical
infusions
(daily or oftener)of
hot (suppose
boiling) water.
The quantity already
in each
Cistern being known
andas also the temperature,
the change of temperature
that would
result from the
infusion of a given
quantity at
a given temperature
might be
previously ascertainable
by calculation.
Tables for this
purpose should
be prepared, & kept
hung up in the Conservatory.
The change of
temperature produced
by the presence
of a given
person for a given
time should be
observed and allowed
for.
The moveable covers for the
temperated cistern
should not cover
the whole of it:
part being reserved
for the thermometer
Doors, two: with
room between them
for a person to
stand to open
the inner door,
after the outer one
has been shut.
To hold the Ice,
instead of Brick,
a wooden Vessel, tarred
& sanded? It
would both take up
less room, and probably
cheaper.
So, the Binns.
The constancy evenness of the
temperature would
preserve the wood
from putrefaction, and
will the constancy of it,
from swelling & shrinking.
