NEEDLES
(Continued)
Selection
of
the
proper
needle
size'is
determined
by
the
size
of
thread
used.
Thread
should
pass
freely
through
needle
eye
in
order
to
produce
a
good
'stitch
formation.
ORDERING
REPAIR
PARTS
ILLUSTRATIONS
This
catalog
has
been
so
arranged
as
to
simplify
the
ordering
of
repair
parts.
EXploded
views
of
the
various
sections
of
the
mechanism
are
shown
so
that
the
parts
may
be
seen
in
their
actual
position
in
the
machine.
On
the
page
opposite
the
illustration
will
be
found
the
listing
of
the
parts
with
their
part
number,
descrip-
tions,
and
the
number
of
pieces
required
in
the
particular
View
being
ShOWn.
The
numbers
in
the
first
column
are
reference
numbers
only,
and
indicate
the
position
of
that
part
in
the
illustration.
The
reference
number
should
never
be
used
in
ordering
parts.
Always
use
the
part
number
shown
in
the
second
column.
Those
component
parts
of
sub-
-assemblies,
which
can be
furnished
for
repairs,
are
indicated
by
the
fact
that
their
descriptions
are
indented
under
the
descriptiOn
of
the
main
sub-
-assembly.
Example:

It
will
be
noted
in
the
above
example
that
the
eccentric
and
bearing
are
not
listed.
The
reason
for
this
is
that
the
replacement
of
any
of
these
parts
individually
is
not
recommended
and
the
complete
sub-assembly
should
be
ordered.
In
those
cases
Where
‘
a
part
is
common
to
all
of
the
machines
covered
by
this
catalog,
no
specific
usage
will
be
mentioned
in
the
description.
However,
when
the
parts
for the
various
machines
are
not
the
same,
the
specific
usage
will
be
mentioned
in
the
descriptions,
and
if
necessary,
the
difference
will
be
shown
in
the
illustration.
At
the
back
of
the
book
will
be
found
a
numerical
index
of
all
the
parts
shown
in
the
illustrations,
which
will
facilitate
locating
the
illustration
and
description
when
only the part
number
is
known.
IDENTIFYING
PARTS
Where
the
construction
permits,
each
part
is
stamped
with
its
part
number.
_
On
some
smaller
parts,
and on
those
where
the
construction
does
not
permit,
an
identification
letter
is
stamped
to
distinguish
the
part
from
similar
ones.
All
part
numbers
represent
the
same
part,
regardless
of
the
catalog
in
which
they
appear.
