army came to MisSOula and made
demonstration before the officials of
the forest service here with the field
signal instruments in use by the army /
which. it is thought might be adopted |
with telling effect by the forest serv-
ice to use in the national forests dur
ing the summer months and fire sea-
sons. their use to help in the matter
of fire patrol. After the demonstration
and field tests Forester W. &. Greeley
of this district prepared a detailed re-
port of the results and made some
recommendations. submitting the same
to the forester at Washington. For
ester Greeley's report in full, follows:
The Cavalry euzzsr.
| On October 10, Lieutenant Standi-
| forle explained to several members OF
the forest service in the district office
at Missoula the uses made ty the sig
nal corps of the cavalry buzzer, the
! field Duzzer, the light buzzer wire and
the 11-strand field wire.
The cavalry buzzer was shown to be
a telegraph and telephone instrument
| combined. 1t weighs seven pounds Is
carried in leather case with a strap
over one shoulder, and works on
either a grounded or metallic circuit
through high resistance. The buzz
is made by pushing a button in the
top of the instrument When the in
strument is used for telegra phing, the
buzzing is sent over the line In a Sc
ries of longs and shorts, in the Morse
code. There are two cups attached to
the instrument ky braided WIRE
which are the telephone transmitter
and receiver. Attached to the trans
mitting cup is little button. which
throws the receiver and transmitter in
and out of the circuit in aOout the
same manner as lifting the receiver off
the hook Of an ordinary telephone In
strument. The buzzer has no bell or
magnetic, and can not ring the tell of
! an ordinary 1900 chm. telephone in
. strument It is made by a foreign
, firm, costs $25 and can probably be
obtained from the disbursing officer
Of the signal corps. United States
. army. Batteries cost 60 cents and last
about six months.
The Field euzxer.
The field Duzzer, model 1908, Is a
, larger and heavier instrument. weighs
pounds, costs $40 and is patented
by the signal corps. 1t is carried in
a square leather case with one shoul-
der strap. 1t is a combination tele-
nhone and telegraph instrument The
buzzing is made by telegraph key
instead of by a button. It's only ad-
vantage over the cavalry buzzer is that
a telegraph operator prefers the tele-
= graph key to the hutton. 1t is not as
II suitable to carry on horseback as the
: cavalry ouzzer.
The light buzzer wire is a three
: stranded insulated wire, containing one
:, strand OF copper and two Of steel
weighing 20 pounds and costing $40. AZ
e per mile. The insulation consists OF
. layer of cotton, layer of rubber
e and layer of saturated braid. A
reel holding one half-mile of wire Il
9 about six inches in diameter and three
: inches wide. The wire can be strung
g on the ground from horseback or h.,
g a person on foot. A playout handle
q is used, costing 40 cents. It has {
d steel shank and fits in.o square holA
q in the center of the reel. A breas
r wheel and crank made especially fo
IT the purpose. are used to reel the wir'
: up. 1t is attached to persons breas
ny strap, and reels up about a!
fast as man can walk The reel cost
$840 Both the reel and the ligh
'buzzer wire are sold by the Nortl
Electric company of Cleveland. Ohio
Lieutendant Standiforde stated tina
1 the buzzer would send a telephone mes
sage over about Is miles of the ligh
L buzzer wire and tuzz over 80. Th
wire will stand a tensile strain of 6
pounds. 1t is merely laid on the groun'
X when used. lieutenant standiford'
u stated that 1t would probably last tw
: field seasons If reeled up in the fall an
:" relaid the following spring; that o.
= account of high voltage of the ouzze
1t would transmit over this wire un
der very adverse circumstances, even
= the wire becomes grounded Oy the in
sulation being broken off, or if tn
40 w.re is broken and the ends touch we
- ground.
&c Eleven. Strand Wire.
