u' , In accordance with the invention, the improved
revaporizer is adapted for use in any liquefied 'gas
system, more particularly _in _connection lwith the
dispensing apparatus disclosed in my copending
application. SerfNo. 98,048. ñled August 26, 1936.
n ji'_.j~Referring mòre- particularly to the drawing,
_ - there is shown a well known commercial liqueñed
' gas system comprisingl a .storage tank ,in_buried
f iii the groundand from which vaporized-gas is
delivered through a‘n underground main or» con
g5' duit. herein shown as being composed o! lsub-
stantially horizontal and‘vertical pipes il and
` i2 leading to the various gas appliances within a
. house i3.
The liquefied gas is stored under pres
sure in the tank id and is vaporized in the tank.
w It is adapted to be delivered from the tank
through a standpipev il, nipple i5,e thence, down
into the pipe 2i where it will be revaporized by
absorbing heat from the surrounding-earth.
To increase the heat exchanging surface of the
pipe 2|, radial iinsß are secured to or formed
on the, pipe, the fins preferably extending nearly 15
the full lengthI of the pipe. The pipe i2 is shown
_ as being surrounded with heat insulating` mate
rial 2l betweenthe ground level and the bottom
of the house to protectthe pipe from freezing .
and to prevent recondensation of the gas at this 20 ‘
point.
_
_
,
At the upper end of the pipe i2 and within
the house, there is shown'an ordinary T 25 hav
ing a short lateral nipple 2t leading to a suitable
cut off valve 21 from which apipe 28 leads to 25
the various gas appliances. 'I‘he upper branch
of the T .2l normally is closed by an ordinary
screw plugl 29 which, however,__'may be removed
so that any condensate from' a poorîgrade-of fuel
which will not revaporize in coldíweather can be '30
' pumped out of the main.
