Cutting Iron With Acctylene.
Indeed. the iron-working machinery
at GorGona is wonderful. You can
See every form Of iron AND steel ere
alton. They have an iron foundry
mere. where they make about 100000
pounds Of casting in i month. The
work IS done by Jamaica negroes IN
der the SUPERVISION Of Americans.
have also brass ~foundries and
everything connected with copper and
tin.
In the iron works l saw them cut
ting immense blocks Of steel with /
blowpipe. The flame fas a mixture
OF oxvgen and acetylene. and Il melt
ed right through the iron as though
the latter were butter. was told
that the principle Was that If the
bloWplpe, and that the pipe was fitted
WITH 4 doubte nozzle. the first Of
which carried oxygen and ac.txlent
and turned the iron to a red heat.
The second nozzle carried 4 stream Of
pure oxygen. and his plaNin1 on the
heated non made II burn like wood.
1t was lust like cutting 4 piece Of
pine with a red-hot poker. SAVE that
the work was more quickly done.
The steel block | saw curt was about
eight inches thick. The man who
handled the hloWpipe wore green
goggles. incascd IN dust projectors. 10

As | saw this flame cutting into the
ircn l asked the engineers whether it
WOuld not be possible TO use the in
Vention in cracking 4 safe. and was
old that the burglars who ecentIy
got away with $4,000 in gold from
sone of the Panama banks had planned
TO Go this on that lob. They came
here to Gorgona ana inquired how
this flame was operated, and they had
even ordered the oXygen and machin-
cry for the work from the states
claiming that they were going to use
it III cutting the girderS Of an old
pier in Ecuador. The Gorsona en-
eineerS kindly showed them the pro
cess, and they We're fully equipped
for using it in that safe burglary. In
deed, the operating machine and the
gases were found in the tunnel otter
they left. They had expected that the
safe floor would be steel, and to USE
this for melting it. But the floor
was only cement. and it broke dowT
uDon them before they knew it was
coming. The resuit was that they
rushed off with their gold, leavins
the machine behind.

During my visit to the Gorgons
shops [ went through the pattern de
partlncnt. in which Uncle Sam ia.
about 10000 patterns of machiner,
and parts Of machinery. These pat
terms are Stlmate to be worth some
thing like $1,000 h models o
all the inventions made by employee
are kept here. and also those of tn,
parts Of patented machines now il
use.
The latter are used for repairin,
big machines. and that because Of tn,
great cost of repair parts. A ma
chine itself may be sold at a profit @
Is to 20 per cent. while the repal
parts for that machine are often sole
at a profit Of 100 or 200 per cent.
Now by our patent laws. if | an
rightly informed here. a man has
right to use a patent machine as lon
as q bit Of the original machine /
left. He could build up the whole in
vention provided he used a bar, Dol
or a nut Of the patented article h
bought and provided he did not HAY
a greater number of such patente'
machines than he had actually pur
chased. OF course it would not b
possible to tear up one machine an
make a lot Of new ones in his way
but one has the right to build ND Oh
machines provided he uses some @
the original parts and does not Great
a numbe of complete ma
chimes than his PURCHASES shows. Tn
Gle Sam finds it cheaper to max
these new parts and repair the oil
machines rather than buy new one
or new parts. Moreover, il
