Ice.MaklBg and Refrigernting Machinery on
Board a Ship.
Yesterday new invention in the shape OF ma
chinery for making ice and performing the rcriger
atng process was tested on board the ship william
TaDer lying ut the foot Of Nineteenth street, Eas
river in the presence Of number Of scientific and
mechanical gentlemen, to whom invitations had
been extended. The ship already named has been
thoroughly lifted with this apparatus for the pre-
servaton, during transportation, OF fresh beef and
other perishable food for long period, and she
will sal for Texas some day next week,
to return with q large cargo. The properties and
designs OF this novel invention may be briefly stated
as folio 8s:-The inventor has contrved series Of
pumps, by means OF which he obtains pressure on
the carbonic acid gas generated in the process Of
working. which was before obtained by the action
OF oil OF vltriol on carbonate Of lime. When these
two properties are brought together they must,
under this process, decompose. He has reduced the
carbonic acid precisely in this way and allows to
escape into bags. BY the application OF
the pumps, which are surrounded with
water, he reduces 1t to liquid state.
The first pump, under this pressure, carries
rs pounds to the square INCH the second 800 and tine
the third II capable Of 1.2v0 pounds to the incn.
which pressure Is amply sufficient to lqufv carbOnlc
acid gas. Having reduced 1t to liquid form 1t
necessarily becomes deprived OF al - calorlc, aud
the moment 1t becomes bera.ed Il again assumes its
gaseous form and takes calOrc from all surrounding
points 1he inventors first idea was to utilize car
bOnic acid gas for the production OF lce One OF the
principal features In the apparatus Is an irOl case
nned W tn copper and through which are copper
tubes SET Ia the top and running clear through
well packed by .otner material to prevent
1t IRON receiving calorlc from the outside. The
tubes are filled with water, which soon becomes
converted into ice. Another novel feature l this In
ventiOn ID that after the gas has performed its office

tity OF water into Ice The expense is limited to the
interest upon tine apparatus used the cost OF given
quantity OF carbonlc acid gas and the cost OF rum
nIng steam engine AMI apparatus to liquify 1t and
turn 1t into gaseous form again. Fifty dollars worth

application Of pumps to the liqueaction Of carOonic
acid gas; and second, the remaking OF 1t into gas

ing the inventor also found that the passage OF
current OF air through the tubes produced an In
tense Cegree OF cold and the idea at once occurred
to him that he could by means OF q .bl0wer,"
