CASE

~o all whom it ~a~ ~nc~n~
Be it known
that I~ OaAzIo
LuGo~
of Flush-
in~ Long I~and~:New
York~ have invented
ce~n hnprovemen~ in E~c~odes for Em-
ployment
in the Production
of Electric
Ligh~
of which
tim ibl~wing
is a spe~ficafion~
My improvemen~
r~ate to the in~oduc~on

making my e~odes tubular or in combim
~g each of them with a tube w~ch is whoJly
or parg~ly
su~ounded
by the carbon
or other
m~e~ of which .the electrode
is composed~
~r the purpose
of affording
a chann~
through
which air or Other
fluids
may be conducted.
~]d may be discharged
~om the p~n~ of the
electrodes
into the ~ect~c
arc.
In another
application
of even date here-
with, de~gnated
as" Case A/I have desc~bed
the use of electrodes
of porous ma~ and
Mso tub~ar
~e~rodes
contusing
fibrous
wick-
lug ~r convey~g
a hydrocarbon
or other com-
bu~i~e
fluid
into the electro
arc by capillary
action.
In my present inven~on I may make my
tubular
electrodes
open at bofl~
ends~
and r~y
upon the naturM
dra~ for creating
a current
of Mr through
them~ or I may connect
them
with pipes~
through
which
~r or any desired
fluid or fluids
may be forced
~om a di~ant
p~nt or p~n~ into and through
the ~ec~odes
with any given
pressure.
The accompanying
drawings

improved
~ec~odes
are as tbHows:

tbr the purpose
of suppling
it w~h fluids
~om two different
sources.
