Threading for
Silent Pictures
Draw off about five feet of leader. In
sert the leader between the upper
sprocket and clamp, engage the perfo
rations with the sprocket teeth, and
close the clamp. (See Figure 5.)
Place the leader between the top
and bottom edge guides of the chan
nel. Form the upper loop as shown
and close the gate by pressing on the
gate latch.
Form the lower loop as shown and
thread the leader between the lower
sprocket and clamp. Engage the per
forations with the sprocket teeth and
close the clamp.
Turn the trial thread knob to en
gage the pulldown claw in the leader
perforations.
Pass the leader over the snubber
roller and under the two rollers on the
bottom of the master-control cover.
Insert the end of the leader into the
slot in the core of the take-up reel.
Take up the slack between the lower
s !"Ocket and the take-up reel.
While the projector is running for
ward, set the speed selector at SI
LENT. Be sure to turn the motor off
momentarily after changing from
sound to silent speeds unless the shut
ter has been locked in the 3-blade posi
tion as shown in Figure 12. (See
KODAK SUPER-40 Shutter, page 12.)
Note: Project at SILENT speed; rewind at
SOUND speed.
Check Setup and Run the Show
Turn the trial thread knob clockwise
a few times to check the threading.
The pulldown claw must engage the
perforations and the sprockets must
feed the film.
The loops must be maintained in
their correct sizes. The leader should
be taut between the supply reel and
the upper sprocket.
Move the master control toward the
right to MOTOR and check to see that
the film is running through properly.
Move the master control lever to
PROJECT.
Focus the image on the screen.
Turn the FRAMING SCREW (Figure
5) to eliminate any blank strip on the
edge of the next picture that shows at
the top or bottom of the screen image.
Adjust the volume control to pro-
vide comfortable listening for the
@
dience. Focus the sound optics to
t the best quality of sound repro
ction by moving the FIDELITY LEVER
and down.
Check to see that the film is being
taken up properly.
For sound projection only:
Check
the lower loop. If necessary depress
and release the loop-forming roller.
This may be done with the projector
running, if desired.
To operate the projector in reverse,
move the master control to the left,
past OFF to MOTOR, and to PRO
JECT if desired. When the projector
is running in reverse, the sound will
be reversed as well as the action. To
eliminate the disturbing sounds that
occur, temporarily turn the amplifier
off by depressing the amplifier power
button. Turn the amplifier back on
when returning to forward operation.
When the last frame of the picture
has passed through the projector
gate, move the master control lever
left to the MOTOR position. This will
move the lamp douser into position
and block off the distracting glare of
white light on the screen. Depress the
amplifier power button to turn off the
amplifier and eliminate the disturb
ing sounds that sometimes occur when
the end of the film is going through
the sound system. When the end of
the film comes out of the projector,
move the master control to the OFF
position, change reels of film, and
thread the projector. If there are no
additional reels to be run, turn off the
lamp switch and rewind the finished
reel of film.
