lparatus and their functions inct29:
ing the inhalation cooler, the ex-
hilation cooler. the breathing bag
the weighted bumper, admission
valve and the safety valye. The
oxygen In the apparatus is % per
cent oxygen and contains from q
to 8 cubic feet. BY valves the
enormous pressure 10 reduced so
as It ran he breathed. In It's travel
around the apparatus the exhtla-
tion air comes in contact with
causic soda which has a great
affinity for the carbon monoxide
and absorbs It. In passing MI.
Forbes discussed mine fires and
explosions at some length.
At the class session the instruc-
tor. Adam Crawford explained the
EAckroyd & Best safety lamps, one
approved by tho United States
bureau Of mines. This is the Eng
llsh type Of lamp, which Is used
In the mine sof Great Britain. Sew
eral of the lamps we're exhibited,
iand partially assembled. It has an
electric relighter and has a COM
lbustion chimney similar in many
respects to the Muese!er type of
lamp. 1t Is not underfed. 1t does
not shed as much light as some OF
tho other lamps and may not be as
sensitive TO gas as some Of the
others although experts do not
agree as to his. The class vas
given a test In giving the parts
,of a Koehler lamp.
Chief points made in instruct
ions of the safety lamp by MI.
Crawford wero as follows: Always
keep tho gauzcs perfectly clean so
las to be free OF SCOT or grease on
thoth the inside and outside; keep
the lower gauze ring brushed and
clean: burn new gauzes before
placing them in tile lamp as they
may smoke the glass: keep this
globe clean by wi2tng with a damp
rag but drying with a dry rag;
remove the SCOT from the bonnet
and when filling the lamp never
put more fuel in the front than
fills the absorbent cotton and pour
off the excess. Be careful and In
rpect your gauzes and G that the
IS mesh wire is intact and not
punctured and that the 7S4 apera-
lures to the square inch are per
feet. Never uso q defective pat in
safety lamp. After d%Iscarding
gauze crush them so no one else
gets the defective gauze. The
globe, gasket and igniter should
nlso he in working order. He eX-
planned the old flame test for gas
US well as the cap test.
Always carry the lamp steadily
and lower cautiously II you strike
d gas pocket. Don't play with
gas" was his admonition because
the flame may pass the sauzes and
1T may prove dangerous In an eX-
plosive mixture.
A new model OF the American
Wolf lamp was showed to the
class. In many respects 1t and the
Koehler are SIMILAR. The rev
Wolf has the expansion ring in
the top of the lamp, the gauzes are
similar to those in the Koehler,
and It is closely bonneted which
perhaps does not give as free II
circulation OF air and the flame
may not be as sensitive to gas as
In tho lamp which is not bonnent-
ed too close.
The class enrolled two members,
Paul c.. Sullivan, Fairmont, repres-
ontative Of the Equitable Fuel
Company, Baltimore. and G. A.
Bennett, FaIrmont, OF the Consol-
tdation Coal Company. The class
now has so members enrolled but
MS some of the members have
missed six weeks an effort will be
made to check up on them before
the list is revised. The class ex-
tended a rising vote Of thanks to
Mr.. Forbes for his address.
