Lewis 150-2 - Page 20

When sewing hems, ribbon hems, and knit materials,
special care must be taken to adjust the retainer close to the
needle. lined up with the ridge forming disc, and with enough
spring pressure to clamp the work firmly against the disc to
overcome the thrust of the needle when piercing the material.
TIMING SKIP STITCH GEARS - See Plate 7
The timing of the skip stitch gears is relative to the
ridge forming disc eccentric. The gear driven pin 22-126 has
a line marked on it. This line when it is at its highest position
and directly over the center of the main shaft should be in line
with the spot screw 18-700 in the eccentric which is spotted on
the main shaft. The timing is made through the small gear on
the main shaft.
Skip stitch LEWIS models may be set to sew so that
the needle penetrates the base lay of the work on every stitch
by setting the stitch selector located on top of the cylinder
base.
