FOCUSING TUBE ASSEMBLY.
On each side of the opening into which the focus-
ing tube assembly (figure 9) is to fit, the outside
edge of the flange projects about 1/ 16 inch for a
distance of about 1 1/ 2 inches . Coat the inside of
the flange at these pOints with black wood lacquer
dope.
Remove the inside focusing tube from the outside
focusing tube.
Turn back the focusing tube insert until it fits
tightly against the focusing tube flange with the stop
stud on the bottom. Do not exert too much pressure
on the insert; otherwise its shape may be distorted,
causing binding of the focusing tube assembly after
it has been reassembled to the camera.
Line up the focusing barrel in the case so that
the stop stud will be on the right-hand side of the
stop plate located in the bottom of the camera case.
Do not attempt to insert thefocusingbarrel into the
case. While in this position, the cutout portion on
the insert is lined up directly above the built-up
portion of the case, and the insert is pencil marked
in this position. The insert is then turned approxi-
mately half way back on the focusing barrel with
the stop stud on the right-hand side of the stop plate.
The focusing barrel is inserted in the case until
the stop stud is beyond the tube opening shoulder of
the case. The insert is then turned back until the
pencil mark on the insert is lined up with the built-
up portion of the case. The tube is then pushed into
the case until it locks into position. Then the re-
taining ring is screwed into position using special
tool No. 501-B.
With the outer tube fully extended, insert the
inside focusing tube in such a manner that when the
inside tube is screwed all the way in, the shutter
operating lever is at the top and the inner end of
the inside focusing tube extends s lightly farther into
the case than the focusing tube flange. To do this
will usually require several trials, starting the
inside focusing tube on different threads of the outer
tube.
Replace the retaining ring lock screw.
Fasten the focusing tube guide assembly (figure
10) to the inside focusing tube with the two upper
focusing tube guide screws (figure 9) and the four
lower focusing tube guide screws (figure 10). The
inner end of the shutter operating lever and end as-
sembly must extend through the slot in the shutter
operating lever slide . Fasten the focusing tube guide
lug assembly to the focusing tube guide assembly
with the two focusing tube guide lug screws. Hook
the guide lug spring over the studs on the focusing
tube guide lug assembly and on the right shutter
operating lever lug assembly.
REPLACEMENT OF SHUTTER (See figure 9).
Insert the shutter light guard in the focusing
tube assembly with the smaller opening toward the
back of the camera and with the large cutout portion
directly in the center of the shutter operating lever
and end assembly.
CAUTION: The shutter light guard is
made of thin metal and should be handled
with care .
If
it is bent by rough handling,
it may bind on the shutter operating disk
and cause faulty operation of the shutter.
Replace the shutter complete in the focusing
-tube-guiding the end of the wire through the open-
ing in the shutter light guard at the sametime guid-
ing the end of the shutter operating lever and end
assembl through the hole in the shutter operating
disk figure 10). Seat the shutter firmly with the
caDre release nut in the cutout slot in the focusing
tube.
With a jeweler's screwdriver, turn on the shut:.
ter retaining ring .
Insert the contact wire, which comes out of the
shutter, into the left side hole of the focusing tube
guide assembly. Insert the ground wire, which ex-
tends from the shutter light guard, in the hole on
the right side of the focusing tube guide assembly .
Fasten the long contact wire to the left side of the
contact plate on the focusing tube guide assembly.
Fasten the ground wire to the contact plate on the
right side of the focusing tube guide assembly .
PARTS ON MECHANISM PLATE.
The range finder couplet bar (figure 11) will fit
into the case with the end having the cutout toward
the back. Push the range finder couplet bar shaft
through the couplet bar until the back end is flush
with the end of the couplet bar.
Extend the focusing tube assembly to the limit
of travel. The front end of the range finder couplet
bar shaft fits in a hole in the front of the case which
is located near the top right corner of the focusing
tube guide assembly. This hole extends through
the case and on the front of the case is covered only
by the leather. With the free end of the range finder
couplet bar spring turned toward the top of the case
and resting against the right-hand spool housing
assembly, insert the projecting end of the range
finder couplet bar shaft in the hole in the case.
Then, allowing the leather covering on the front of
the case to be pushed out, push the front end of the
shaft far enough into the hole so that the back end
of the shaft can be slipped past the overhanging back
edge of the mechanism plate. Guiding the back end
of the shaft into the hole in the mechanism plate,
push down the leather on the front of the case with
the flat side of a screwdriver blade.
In
order to prevent the range finder adjusting
screw bracket (figure 1) from catching on the range
finder couplet bar and throwing the range finder out
of adjustment, follow the instructions givenonpage
4.
Check the focusing tube assembly to make sure
that it operates smoothly, without binding or side
play. Since the upper guide rod is eccentric at one
end, it provides an adjustment of the sidewise mo-
tion of the focusing tube assembly as the latter is
extended or retracted . By means of the screw-
driver slot in the back end, turn the guide rod as
required for smooth operation of the focusing tube
assembly . If not enough adjustment can be obtained
with the guide rod, loosen the two focusing tube guide
lug screws (figure 10), the focusing tube guideTug
assembly as required , and tighten the screws.
Place the key post gear (figure 8) over the pin
on the key complete. The flattened sides of the key
post gear pin must be turned vertically to allow the
gear to seat properly over the pin. Then place the
key post wa1lher over the key post gear and replace
