TO
ADJUST
THE
FEED
DOG
The
feed
dog
should rise
and
show a full
tooth
above the
throat plate as the eyes of the needles come up level with the
plateafter
forming
the third stitch in the
opening.
The
feed
dog
should not begin to move forward for the next opening until the
needle points are clear of
the
goods.
The
feed dog
must
be kept level so as to afford the best
condition for handling the material. To level the feed dog use
adjusting screw at (ee, see Fig. 2) and secure by check nut.
TO
RAISE
OR
LOWER
THE
FEED
DOG
See
Fig.
2
Clean the lint and dirt from
it;
tip back the machine and
turn the balance
wheel
toward you until the
feed
is at its highest
position; loosenthe screw of crank (dd) and
move
it up or down
until the feed is at the desired height and tighten the screw in
crank
(dd).
The feed dog does not require adjusting except for some
unusual
kind
of
work
or
if
badl}*^
worn.
FEED
ADJUSTMENTS
See
Fig.
2
The
feed
adjustments
which
follow
are
seldom
required,
but, if an adjustment becomes necessary, take care that the
position of the other parts is not changed.
To
cause
the
feed
to start
earlier
after the
feed
dog
is up
and the needles are clear of the goods, carefully loosen the screws
in feed driving gear (ii) and slightly turn the top of the feed driv
ing gear toward you, which sets cam and gear (jj) forward, be
careful not to make too great a change, then tighten the screws
firmly.
If the
feed
does
not start as early as
required,
repeat
the
operation. To make the
feed
start later
move
the top of
feed
driving gear (ii) slightly
from
you. Any change made in the
time
of
cam
and gear (jj)
may
necessitate
a
change
of the
posi
tion of feed lifting cam
(V).
For an
earlier
drop
of the
feed
dog,
move
or set the
top
of
cam
(V)
from
you,
and for a later
drop
of the
feed
dog,
move
or
set
it
toward
you.
