NEW SMELLING METHODS
JOhRSon'S Oil Burner Will ReVOIu-
tiOnize Mining:

( An invention which promises to rev.
olutionize smelling and at the same
/ time furnish . new market for crude
I petroleum was thoroughly tested and
( its workings fully demonstrated a few
weeks ago in San Francisco before L
large audience OF scientists and promi-
nent mining engineers.
Among these present were Mr.. Rapp.
Of the Selby Smelling works, ]. w.
Waite, of the Western Refinery Co. Mr..
Shafter Howard, Mr.. Nathan Dodge, of
the Spence Mineral Co, D. Martin. an
Arizona mining man, and many others.
whose technical knowledge of such
things made the gathering a notable
one.
The invention is known as Johnson's
oil burner and the simplest principles of
mechanism are involved in the device
which affords the highest heat attain
able from a composition of oil and air.
A small five-ton snelter was roughly
constructed for the experiment. The
first test was on lot of copper ore be-
longing to VIM. Robinson of Barstow,
California. This was followed by a lot
of iron ore furnished by the Spence
Milling Co.
The tests proved to the utmost sat
isfactiOn of the critical audience that
the burner was all that had been claim
ed for it by its inventor.
Speaking Of the invention the Daily
Record of San Francisco, says:
The device is simple in its workings
=
coke Of from 40 to 50 per cent on a San
Francisco basis as to the price of the
two fuels.
1t consists of a novel construction OF
mixing and burning tubes with a pecu-
Darly shaped discharge nozzle, with the
means such as a damper for regulating
the quantity and force of air. which is
supplied by an ordinary rotary blower
The construction is such as to cause a
YapoTization of the oil and mixture
18th the air, which is injected into the
furnace By the continuous blast of the
blower. 1t must be borne in mind that
this device GCes rot require the use of
suN-r-ht atcd air or steam. but is only
combioatiCI Of air, as il comes from
tie blower, and the oil that trickIes
down iHtO the valves of the nozzle by
EiiNitaticn. The result of this simple
heat predicting formula is wonderful in
lis inteEs.ty-a stream of fire that con-
VeTts the most rebellious ore into mol
ten metal can be thrown a distance of
Efty Feet. or by a simple turn of the
damper regulating the air passages the
flame may be reduced to Pickering
light.
THE burner can be attached to any
snelter and can be operated by a
child. 1t is in it's economy and use of
a portable fuel that the invention COM
mencs Itself. In remote and inaccessi-
bic sections where the cost of transpor-
taticn fCrbids the successful treatment
OF rebellious ores this device makes pos
sible the profitable operation of a
smelter. Using crude oil, IN place of sx-
pensive and bulky coke. the johnson
burner will revolutionize mining and
bring into activity and successful oper-
alton thousands of mining properties of
low-grade ore which are abandoned as
aifording no profit to work.
1t performs its task rapidly. and
with the utmost economy; the oil
flows down from barrel by gravita-
ticn, the turn of a faucet and the fuel
flows or is shut off. An ordinary
blower Of eight ounce pressure, and
there is the apparatus ready for
work, or center shut off without loss of
drop Of fuel or a moments delay.
Tt gives forth the highest heat pos
siole to attain and it can be employed
with success and economy under
kilHs, pottsries, cTucible furnaces,
and in any furnace where high heat is
