3. OPERATION c. The selector switch lock component of the
"cam and hub assembly, counter wheel" (Item
2, Fig.
The Model
5210 Wall Box is mechanically operat-
5) is the next to function by releasing the "arm, hub,
ed by its drive motor (Item
2, Fig. 4), through one and roller assemhly" just enough to permit latching
complete cycle of operation for each selection made, of the selector switches. The "lock bar and adjustinp
-
screw assemhly"(1tem 1, Fig. 3)is actuated bymove-
mentof the arm(Item 6)to produce the latching action
described above.
d. The next action will he produced, again, by
the "cam, hub, and pin assembly" (Item
5, Fig. 6)
to actuate the "lifter lever assembly" (Item 7) and the
"coin feelerand lever assembly" (Item 6). This action
moves the coin feeler (Item 1) across the three coin
exits of the slug rejector and the feeler therefore
is
intercepted in one of three different positions. The
opposite end of the "feeler and lever" (Item
8) is thus
positioned
in one of three different planes to engage
the "coin counter wheel and plate assemhly"(Item
9).
e. As the cycle advances, the "cam and hub as-
semblyV(Item
2, Fig. 5) again acts to further release
the button latch bar and produce complete locking of

In mechanical sequence, the function of the
"cam, hub, and ptn assembly" (Item
1) is first to re-
lease the "slug rejector lock assembly" (Item 6) and
effect coin return during the selection cycle, also to
prevent acceptance of more than one coin at a time.

g. Further action ol the coin counter cam actu-
ates the "arm and link assembly" (Item
4. Fig. 7).
The arm and link, heing linked to the "coin counter
p
wheel and plate assemhly", will rotate the wheel to
be engaged hy the end of the "coin feeler and lever
assemhly" as described in "d". The "arm and link
assemhly"
is provided with a yielding link (Item 3)
and spring(Item 5) to permit continuation of the cam
action without advancing the counter wheel beyond its
point of engagement, with the end of the "coin feeler
and lever assemhly" (Item 6).
h. As the coincounter cam passes its maximum
point of actuation the cam follower on the yielding
memher of the "arm and link assemhly" drops down
the "quick returnWsideof the cam, returning the coin
counter plate group to its "at rest" position and leav-
ing the coin counter wheel, held hy the detent spring,
ata pre-determined position as set up hy the credit
settings of the coin counter disc group. Pressure is
thus released from the "coin feeler and lever as'-
sembly".

i. The next action takes place due to the "quick
return" side of the "cam, hub, and pin assembly"
which started its functions in "h". The "lifter lever"
is thus released and the "coin feelerand lever assem-
hub, and pin assemhly". The round head of the screw,
at this time, engages the cam shaped end of the "coin
paddle mounting bracket" (See Item
2, Fig. 7) and
swings the coin paddle from under the coin exits of
the slugrejector to drop the coin (See Items
4 and 3,
Fig. 6).
k. Concurrently with the "coin drop" action,
cancel action
is provided by the return of the cancel
cam component of the "cam, hub, and pin assemhly"
to its original "at rest" position (See Item
1, Fig. 5).
1. The next phase provides return of the coin
paddle under spring loading (Item
2, Fig. 6) due to
passing of theround head screwbeyond thecamshaped
end of the coin paddle mounting bracket.
m. The final phase for the "cam, hub, and pin
assembly" re-engages the pin with the actuating arm
of the slug rejector lock assemhly (Item
4, Fig. 5).
n. Concurrently with the action described in
"m" the "selector switch lock"component of the "cam,
and hub assembly, counter wheel" actuates the "arm,
hub, and roller assemhly" to again release the se-
lector buttons to their "at rest" or "make selection"
positions, as determined hy the electrical condition
of the key switch.
'
o. The electrical conditions pertaining to the
various phases of the cycle may he obtained by noting
the functional schematic (Page 13)and watching the
position of the "coupling, insulator and spring as-
sembly" with relation to its accompanying "contact
plate assemhly".
p. During one complete cycle as described a-
hove, the coin counter wheel and plate assemhly will
function to set up credits in accordance with the de-
nomination of the coin which intercepts the coin feel-
er. The credit action for a nickel has been described
in "d", and shown as Item
9, Fig. 6.

5. ADJUSTMENTS
a. Slug Rejector.
The slug rejector
is a product of National
Rejectors, Inc. of St. Louis, Missouri. Information
may be obtained from any of their branch offices by
sending for their "Rejector Manual". Adjustments
should bemade in accordancewith their recommenda-
tions.
b. Coin Switch Adjustment. (Fig. 10)
To adjust the coin switch, the mechanism
should be in its "at rest" position with the slug re-
jector in place.
(1) Located in theright hand bracket for the
selector button assembly, there
is a slide switch
(Item 3, Fig.
10) for use in servicing the mechanism.
Turn this switch off and insert a coin in the slug re-
jector.
(2) Loosen the coin switch mounting screws
(Item 2, Fig.
10) and move the switch on its mount-
f-* ing plate to a position that will provide actuating
overtravel of the switch arm (Item 1) when the coin
paddle(Item 4)is depressed by an accepted coin (Item
5). The amount of overtravel should be about equal
when the switch actuates in either direction.

Cancel Teeth of Coin Counter Wheel
(1) Set the main shaft and cam assembly m
a position where the cancel slide (Item 2) is actuated
to maximum. The cancel slide must float freely in
a
lateral direction on its lower guide (shoulder screw,
,?
Item 6). The cancel slide actuating spring (Item 1)
functions to engage the slide and bracket assembly
with the cancel teeth (Item
9) of the coin counter
wheel.
(2) Set the coin counter wheel in its fbst
detent position (no credits) and adjust the bracket
(Item
5) to provide engagement with the first cancel
tooth(Item 4) to a depth no greaterthan one
half of the
depth of the tooth (Item 3). At this setting the cancel
slide should be at
its extreme lateral position toward
the counter wheel as indicated
by arrow (Item 7).
(3) Tighten the two mounting screws (Item
8) and re-inspect for correct setting.
(4) Checkoperation, under power, atvarious
detent positions. Cancellation should be one full de-
tent position for each cycle of operation. Any varia-
tion should be corrected by repeating steps
(1) to (3).
h. Slug Rejector Stop Bracket Adjustment.
(Fig. 16)
(1) Adjust the slug rejector stop bracket
(Item 6, Fig. 16)to position
its under surface 1/16"
below the parallel lower surface of the three coin
exits. When properly adjusted, the coin feeler
will
-
slide freely over the stopbracket and will also slide
freely under the three coin exits of the slug rejector
without interference with coin paddle function.
i. Coin Drop Adjustment. (Fig. 18)
(1) Advance the cycle to a point where the
round head screw (Item 3, Fig. 18) causes maximum
deflection of the cam shaped end of the coin paddle
mounting bracket (Item
2).
(2) Loosen the lock nut (Item 4) and adjust
the round head screw to provide 1/8"minimum clear-
ance (Item
5) between the coin paddle arm and the
coin switch.
(3) Insert a quarter and power operate the
mechanism, observing the clearance between the coin
(Item 1)and the coin paddle (Item
6) at the coin drop
phase of operation. The coin must be freely released
to drop
in the coin box.
j. Cam
Shaft End Play Adjustment.
On the left of the main cam shaft assembly
is a collar with a socket head set screw. This collar
rr,
should be positioned and locked to the cam shaft at a
point where clearance hetween the collar and the
flanged surface of the left end hearing will be .003"
to .007".

in the "at rest." phase of the cycle, set the ad-
justing screws(Item 3, Fig. 20)to just produce latch-
ing action of the switch rods (Item 3, Fig. 21) when
buttons
are pressed.
(2) Slowly turn the adjusting screws in until
the latched button
is released.
(3) From this point, turn the screw
in one

(5) During the selection phase of the cycle,
when thecam follower
is on the lowsection of the cam
(Item
4, Fig. 19), the selector switches will be latch-
ed to the full depth as shown at Item 2, Figure 21,
where no buttons may bepressed andnone may be re-
leased. Under operating conditions, release of the
buttons must not occur before the selector contact of
the "coupling insulator and spring assembly" has
passed the last pulse patch on the contact plate.
1. Test Requirements, Mechanical.
For trouble free operation, the wall box
should meet the following test requirements:
(1) With power off, place the cam shaft in
the normal "at rest" phase.
(2) Drop a dime into the slug rejector. With
the dime resting on the coin paddle, advance the cycle
until the coin feeler rests against the dime, and the
ten cent coin counter disc
is approaching the right
hand tip of the coin feeler lever. There should be
1/32" to 1/16" clearance between the tip of the coin
feelerlever and thesurfaceof the five centcoincount-
er disc as descrLbed in paragraph f, (2). Continue
advancing the cycle until the coin counter.disc stops
against the tipof the coin feelerlever.
In this position
the detent spring should be resting in the second or
third detent for one or two plays asdesired.
(3) Test the coin counter action for quarter
play in the same manner described
in (2). The detent
spring should be resting in the fourth, fifth, sixth or
seventh detent for 3,
4, 5, or 6 plays, as desired.
m. TestRequirements, Electrical.
(1) Set the coin switch ihthe "Off" position
and the key switch open.
(2) Set the mechanism
in the "at restMposi-
tion and the service switch
"On", and manually turn
the "coupling, insulator, and springassembly", in
a
clockwise direction, asviewed from the motor end,
?
until the rotor contacts completes a circuit to the
motor, which
will tend to drive the coupling in the
opposite direction. This action must occur when the
long contact arm
is still on the "at rest" patch of the
contact plate.
(3)
Turn the service switch "off and man-
ually turn the "coupling, insulator, and springassem-
bly" counter-clockwise, as viewed from the motor
end, until the cam follower of the "arm, hub, and
roller assembly" is on the hi&est point of the '%utton
latch cam". Turn the service switch on. The motor
must drive thecontact arm on to the "make selection"
patch, and the "button latch cam" to the "make se-
lection" position.
(4) Turn the senrice switch "off". Set the
long contact arm in the blank space between the "at
rest" and "make selection" patches. Turn the ser-
vice switch "on". Power must drive the long con-
tact arm on to the "make selection" patch.
(5) With the mechanism in the "make se-
lection" position, turn the service switch "off" and
turn the cam and shaft assembly clockwise, asview-
ed from the motor end, until stopped against the high
point of the button latch cam. Turn the service switch
n
"on". The long arm contact must still be on the
"make selection" patch.
(6) With the power
still on, advance the long
arm contact along the "make selection" patch in its
normal direction. Before the contact leaves the "make
selection" patch, the motor must start and drive the
mechanism through onecycle to the "at rest"position.
NOTE:
The timing factor is determined by fixture
88semhlv in oroduction.

Failure to perform as deacrlbed above may
indicate bentcontact arms, bentdrive pinor electrical
6. MAINTENANCE
For trouble free operation of this equipment,
"preventive service" or well organized maintenance
is recommended.
(1) Cams, linkage, detent and cancel teeth of the
coincounterwheel, and gearteethshould be lubricated
with Houghton Absorbed Oil, Type

2. OPERATION
Both of the stepping units (Fig. 25) function in
the same elecnical and mechanical manner.
a. The step magnet (Item
9) pulls the armature
(Item
7) down, actuating the driving pawl (Item 1)
and closing the pulse switch (Item 10). As the driving
pawl engages the ratchet wheel (Item
4) the stepper
contact arm (Item
8) is advanced. Due to closing of
the contacts of the pulse switch, the release relay
(Item
2) will be energized and the holding dog (Item
3) engaged with the ratchet wheel to hold the ad-
vanced contact blade for succeeding selection pulses.
h. The timtng relay (Item
10, Fig. 23) and the
P
releaserelaywill hold their charge for a short period
after their coil circuits have been opened. This de-
layed action permits rapid release and re-energizing
of the step magnet to advance the stepper arm as
desired.
The Rudolph Wurlitzer Co. Model
2000
c. The transfer relay, shown at Item
9, Figure
23, shifts the wall box pulse circuit from the letter
stepping unit to the
number stepping unit to provide
for selection of the proper number group.
d. The
500 Mfd. capacitor, shown at Item 2,
Figure 24, provides current for holding the letter re-
leaserelay until the number group has heen selected
and their associated "common contacts" (Items
6 and
7) pass current to the selected number group relay
and the selected letter latch coil of that particular
number group. The rotory contact armsfunction as
an integral part of theratchet wheel and shaft ilssem-
bly. These arms are retracted to their original
positions by torsion springs when the release relays
are de-energized and the holding dogs (Item
3, Fig.
25) released from the ratchet wheels.

opening of contacts
1 and 2 isolates the 24V. A.C.
circuit to be used later for operation of the transfer

1 is thus energized
and provided with
500 Mfd. as a D.C. power supply,
to keep it energized during the transferfrom letter to
number stepping phases.
h. When release relay number 1
is energized,
its contacts
1 and 2, and also 6 and 7 are opened.
Contacts
3 and 4 close. Contacts 1 and 2, having per-
formed their function in Phase
2, isolate that section
of the circuituntil all phases of the sequence arecom-
pleted as shown in Phase
1. The latching action of re-
lease relay No. 1 will prevent the letter stepping arm
from return action until after
all pulses from thewall
box have been completed. The stepping arm
will
therefore advance to the selected letter contact and
remain there until the selection pulse has been com-
,-
pleted.
