DESCRIPTION
Machine 15-90,
for family use, has an oscillating
shuttle on a horizontal axis and makes the lock stitch.
It has reverse feeding mechanism by means of
which the machine stitches as readily in a reverse
direction as it does in a forward direction.
It is especially designed for operation by elec-
tricity, having an electric motor attached to the
upright part of its arm. The motor drives the ma-
chine through a belt.
It is also equipped with an electric Singerlight.
Before starting to darn or embroider, make the
simple adjustment on the machine, as instructed
on page 33.

Motor Can be Operated on Either Alternating
Current or Direct Current
The electric 'motor, which is located at the back
of the machine, can be operated on either alternat-
ing current or direct current, as desired. The
standard windings of the motor are for 110 volts,
and motors can be furnished for any voltage be-
tween 100 and 250.
Special motors for 32 volts direct current, and
for 50 volts alternating current and direct current,
have also been developed and are available.
Points to Determine Before Connecting
Motor to Electric Service Line
Obtain the following'information from the Elec-
tric Light Company which supplies the electric
current for the circuit to which the motor is to
be connected:
1.
If current is direct, what is the voltage? The
voltage must be within the range stamped on the
name plate of the motor.
2.
If current is alternating, in addition to the
voltage, what is the number of cycles? The number
of cycles must be within the range stamped on the
name plate of the motor.
The voltage of any circuit and, if alternating
current, the number of cycles, can be verified by
looking at the name plate on service watt meter
installed by the local Electric Light Company.

To Prepare for Sewing
With the left hand, hold the end of the needle
thread, leaving it slack from the hand to the needle.
Turn the bal-

ance wheel
over toward you
until the needle
moves down and
up again to its
highest position,
thus catching the
bobbin thread.
Draw up the
needle thread
and the bobbin
thread will come
up with it through the 'hole in the throat plate,
as shown in Fig. 13. Lay both threads back
under the, presser foot di-
agonally across the feed,
as shown in Fig. 13A, to
the right or left, depend-
ing upon which side of the
needle the material is to
be located, so that when
the presser foot is lowered,
the threads will be firmly

To Commence Sewing
Place the material beneath the presser foot, Power
the presser foot and commence to sew.
When sewing thick material, it may be necessary
to turn the balance wheel over toward you byhand
to start the machine. This should also be done if
the machine stops when sewing across thick seams.

To Remove the Work
Stop the machine with the thread take-up lever
(5, Fig. 12) at its highest position, raise the presser
foot and draw the fabric back and to the left, pass
the threads over the thread cutter (A, Fig. 13) and
pull down lightly to sever them. Leave the ends of
the threads under the presser foot.
To Turn a Corner
'Stop the machine when the needle is commencing
its upward stroke. Raise the presser foot and turn
the work as desired, using the needle as a pivot,
then lower the presser foot.
To Regulate the Pressure on the Material
For ordinary family sewing, it is seldom necessary
to change the pressure on the material. If sewin
fine silk or flimsy material; lighten the pressure b
turning the thumb screw (A, Fig. 24) on the top o
the machine over to the left so that it screws up. Tc
increase the pressure, turn this thumb screw over t
the right so that it screws down. The pressur
should be only heavy enough to prevent the materia
from rising with the needle and to enable the feed t
move the work along evenly. The heavier the ma
terial, the heavier the pressure; the lighter th
material, the lighter the pressure.

To Regulate the Direction of Feed
To feed the goods from you,
push down the
stitch regulator lever (B, Fig. 14) as far as it will go.

raise the stitch
egulator lever (B) as high as it will go.

The direction of feed can be reversed at any point
f a seam without removing the work from the
`achine.
, Back tacking is therefore readily accomplished
nd the fastening of the ends of seams is made easy.
