SIXTH VANE EX'l'ENSION Sffi!NG COMPRESSION
(Figure
25)
On
typing units equipped wi th the new style sixth vane extension,
(a formed pi ece of steel mounted on the sixth vane by means of shoulder screws
and compression springs), measure the compression df the springs as follows:
Back orr the left pilot screw (Figure
24)
and remove the sixth vane
from the typing unit. With the vane held in a horizontal position and with
the vane extension extending upward, hook an
8
oz. scale over the upper end ot
the extension.
Pulling at right angles and toward the front or the vane, it
should require
3/4
to
1-1/4
ozs. to start the extension moving away from the
vane.
Check this spring compression in the opposite direction by hoold.ng the
scale over the end of the extension and pulling toward the rear edge of the
vane." Replace the sixth vane.
SIXTH VANE ADJUSTMENT
(Figure
24)
There should be
.008"
to
.030"
clearance between the right edge of
the sixth vane extension arrl the right end of the slot in the unshift push bar.
The vane should have some em pla_y, not more than
.-004".
To adjust, loosen the
vane clamping screws
and
position the sixth vane
by
.means of its pilot screws.
Tighten the clamping screws.
SELECTOR VANES ADJUSTt\ENT
(Figure

The forked arms of Nos.
1, 2, 3, 4,
and
5
vanes should line up with
their respective T levers. When the printing bail is in its extreme rear .posi
tion, each vane should have some end play, not more than
.004*'•
To adjust,
loosen the vane clamping screws and position the vanes by means or their pilot
screws. Tighten the clamping screws.

With the function bail in its extreme rear position, unhook the
function bail spring from the front spring post and hook
a
4
lb. ,scale in the
spring eye. It should require
2
to
3
lbs.
to
ext;eBi the spring to its position
length.

extreme
rear
posi. tion. Hook a
12
lb. scale over the left end of the adjusting lever,
so
that the hook on the scale engages the lever directly in the rear or the spring
notch in the lever, and pull in line with the spring. It should require
6-1/2
to
8-1/2
