vides adequate protection in localities
where there are
no electric
light or power circuits.
The No. 60-AP protector (see
figure 9) is of the
openspace
cut-out type. It consistsof a baseand cover,
mounting 4 protector blocks. Two of the protector
blocks are of carbon and are assemblednearest
the center
of the protectbr. The other two protector blocks consist
of carbon inserts mounted in porcelain in such a manner
that they are slightly depressedbelow the surface of the
porcelain
on the side adjacent to the plain carbon
block,
thus forming the open spaceacross which high potential
currents may escape to the ground. The porcelain
blocks containing the carbon inserts are placed outside
the other blocks with the springs resting in the grooves
(see
figure 9).
If there is danger from power and light circuits as
well as from lightning, the No. 58-AP protector or the
No. 58-B protector, which contain fuses
in addition to
the openspace cut-outs,
should
be used. The No. 58-AP
protectbr uses the same type of protector blocks as the
No. 60-AP protector. The No. 58-B protector employs
four metal blocks, two of which are grooved and are
assembledoutside of the other blocks, with the springs
,
resting in the grooves. A specially prepared piece of
mica, known as a No. 10 protector mica is assembled
betweeneach.
pair of metal blocks.
Connecting the Telephone Set
The telephone line wire should be connected to the
protector as shown in figure 10 in the caseof a metallic

In order to make a good
connection
with the ground
rod, clean
the surface
of the rod and then twist tlie bare
wire around
the rod five or six times and solder.
If it is desired to use a water pipe for the ground
connection,
a ground clamp should bs fastened s6curely
to the water pipe or to someother pipe which makes'a
g_ood
connect:ion with the ground'.
' Clean the pipe
thoroughly so that a good electrical contact may be
made, then fasten the ground clamp securely to the
pipe and solderthe ground wire to the clamp.
The ground wire should be led with as few bends
as
possible
from the protector to the ground connection.
Connecting the Dry Cells
The dry cells should be connected
in series,i.e.,
connect
the center terminal of the first cell to the outside
terminal of the second
cell (in
the caseof three cell sets.also
connect the outside terminal
of the third cell to the center
terminal of the second
cell).
The remaining
two terminals
should be connected to the
two wires which extend into
the battery compartment (see
figure 12), as shown on the
circuit label nasted on the
inside
of the cover.

ADJUSTING NO. 131?
TELNPIIONE SETS
When the telephone set leaves the factory, all parts
are adjusted to operate satisfactorily under ordinary
conditions. The apparatus
neednot be disturbed unless
it does not operate properly, but if it is necessaryto
change the adjustment, the following rules should be
observed:
Bingcr AdJustment
The movement of the clapper ball of the ringer
shown
in figure 13 should be l/L6". If the movement
requires adjustment,
turn the screw "4"
(see figure 13) to the

stroke,
until a movement of
L/L6" is obtained.
The clapper ball
should strike the gongs
but should not rest
against them when
thrown to either side.
The adjustment for this may be made by loosening
the two clamping screws "B" and turning the two ec-
centric screws
"C" until the correct nosition is obtained.
Then tighten the clamping
screws
"B' (see
figure L3).
Note: In ease the ringer is of the design shown in
figure 14, the movement of the clapper ball
sllould be 5/64". If the movement requires

If the ringer is equipped with a biasing spring "S"
as shown in figure 14 (i.e., a spring which holds the
clapper ball toward one of the gongs),
the tension of the
spring should be such that when the armature is forced
away from the pole-piece
against which it normally rests,
and is returned by'the spring tension, the clapper ball will
strike the gong, but will not rest against the gong. The
tension of the spring is adjusted by turning the adjusting
stud to which one end of the spring is fastened.
IIow to Install a Condenser
It is sometimesdesirable to connect a condenserin
series
with the receiver in order to insure that the bell
can be rung even if the receiver is left ofr the hook.

TESTING NO. 1317 TELNPHONN SNTS
How to Make Test
After installing the telephone
set, it should be tested
as
follows:
1. Turn the handle of the generator. This should
cause
the bell to ring.
2. Take a short niece of wire and connect one end
to the terminal
marked "Line 1" (or "L1") and the other
end to the terminal marked "Line 2" (or "L2"). Turn
the handle of the generator. It should now turn harder
than beforeand the bell should not ring.
3. Leave the short piece
of wire connectedto "Line
1" and "Line 2." Take the receiver off the hook and
hold it to the ear. Then talk into the transmitter or
move the switchhook up and down. Soundsshould be
heardin the receiver
If the above tests show the telephone set to be in
proper working condition, remove the short piece
of wire
mentioned above and connect the two wires of the tele-
phone
line to the terminals marked "Line 1" and "Line2"
(or "L1" and "L2") as
shown
in figure 10. When there
is only onewire, connect
as
shown
in figure 11.
The telephone set is now connected and ready for
use. To call central or subscribers on the same line, give
the handle of the generator two or three turns. If there
are a number of subscribers on the same line, a pre-
arranged
code of signals is neeessary,usually a series of
long and short rings to indicate which subscriber is being
called.

IIOIV TO CLEAB TROUBLE
If the telephone set does not work properly, the
trouble
may be out on the line, in the interior wiring in
the building, in the ground connection
or in the telephone
set. The following paragraphs outline various possible
troubles and the methods to be used in correcting them:
1. You cannot ring up anyone. Your generator
handle turns hard. Your bell does not ring when
you turn the generator handle.
When testing to discover the cause
of this trouble
be sure to leave the receiveron the switchhook.
Disconnectthe two wires.
which enter
the telephone
set,
from the terminals markbd "Line 1" and "Line 2"
(or
"L1" and
"L2") and make surethat the wires
leading
from the ringer are tightly connected to these terminals.
Turn the generator handle. If the handle turns easily
and
the bell
on
the telephone
setrings,
the
trouble is not in the
telephone set. Connect the line'wires again to the ter-
minalsmarked
"Line 1" and
"Line 2" (or "L11'and "L2")
and disconnectthe line wires from the protector. The
wires
from the telephone set
to the protector
should
not
be removed. Turn the generator
handle and if it turns
hard, remove the protector blocks from the protector
and ihen turn the ^generator
handle again. If- it turns
easily, examine the protector blocks to see that they
have not been damaged
so
that the carbon insert touches
the adjacent carbon block when mounted in the pro-
tector. Clean the protector blocks with a stiff brush
and put them. back into the protector. (In the case
of the No. 58-B protector, be sure to place the thin
piece
of mica between them). After replacing the blocks,
turn the generator handle again and if it operates
easily,
connect the line wires to the protector and then see if
the telephoneset works properly.
19
G

If, after the protector blocks have been replaced,
the generator handle turns easily when the line wires
are disconnected
at the proteetor, but turns hard when
the line wires are again attached, the trouble is either in
the line or in the wiring or apparatus of one of the other
telephone
sets on the line. Examine the wiring and line
carefully for a place where one wire crossesanother or
a place where two wires have been fastened under the
same staple. If no trouble is found with the wiring,
look for a place where the telephone line comes
in con-
tact with a tree or the ground, or where one
wire touches
another.
If, with the wires disconnectedfrom terminals "Line
1" and "Line 2" (or "L1" and "L2") in the telephone
set, the generator handle turns hard and the bell does
not ring, it indicates that the trouble is in the set, and
that the wiring of the set may have become damaged
in
unpacking or installing. The wiring should be in ac-
cordancewith the diagram fastenedto the inside of the
door of the telephoneset.
2. You eannot ring up anyone. Your generator
handle turns easily. Your bell rings when you
turn the generator handle.
Look for a looseconnectionat terminals "Line 1"
and "Line 2" (or "L1" and "L2") of the telephoneset.at
the terminals irf the protector, or where
the inside wiring
is connectedto the outside wires. If the trouble is not
located at these points, look for a broken wire or poor
ground connection,
S. You cannot ring up anyone. Your generator
handle turns easily. Your bell does not ring when
you turn the generator handle.
Look for a loose
connection
or a broken
wire in the
telephone
set. It may be that one of the wires to the
-20

e
ii'
e
generator is disconnected
or one of the line wires or one
of the ringer wires may be loose. :
4. You cannot ring other bells on the line
very well. Your bell rings when you turn the
generator handle.
Look for a loose connection at terminals "Line 1"
and
"Line 2" (or "L1" and "L2") of the telephone
set,
at
the terminals of the protector, where the inside wiring is
connected
to the outsidewiresor at the ground
connection.
It is possible
that the trouble may be due to a poor splice
in the line wire or to contact between the line wire and
trees.
5. Your bell does not ring but you are able
to ring up other stations on the line.
Look for a broken wire or loose connection in the
wires leading from the ringer. If the connections and
wiresare
in good
condition,see
that the ringer
is
properly
adjusted. (See
"Ringer Adjustment," page
15.)
If the bell will not ring, the fine wire used for winding
the ringer coils may be broken or burned out. If such is
the case,
new
ringer
coils
will be required. Sendthe ringer
to the nearestdistributor listed in this bulletin for repairs.
6. You can hear others but others cannot
hear you.
Look for a looseconnection
or a broken wire leading
from the transmitter, or battery. Examine the wires
connecting the dry cells. Seeif the connections
to the
induction coil are made in accordancewith the diagram
fastened to the inside of the door of the telephone set.
If this examination does
not disclosethe troubie, tap the
underside of the transmitter lightly with the hand. If
this does
not remedy the trouble, it may be due to ex-
2l
|. "*.

hausted dry cells. This condition may be quickly de-
termined by meansof a Western Electric No. 35 battery
gauge. When it is necessaryto replace the dry cells,
be surethat they are fresh and replaceall the cells at one
time. Never connecta new
cell
to old cells.
7. You cannot hear others but others can
hear you.
Look for a loose connection or broken wire leading
from the receiver, switchhook, or induction coil. Be sure
that the ear cap of the receiver is screwed
up tight, if
not, it may be
the cause
of the trouble. If the ear cap
is
tight, the trouble may be in the diaphragm. Remove
the ear cap from the receiver and clean the diaphragm.
If the diaphragm is bent or otherwise injured, a new
one will be required
If this does not remedy the trouble, remove the
receiver cord from the terminals marked "REC" and,
while holding the receiver to the ear, touch the two
terminals of the receiver cord to the terminals of one of
the dry cells. If a click is heard in the receiver whenever
this connection to the dry cell is either made or broken,
the receiver
is in good condition. If no click is heard,
the receiver or the receiver cord is probably damaged
and should be replaced.
8. Neither you nor others can hear distinctly.
This is an indication of loose
connections
or poor
joints either in the wiring of the telephone set or in the
liue,
