The Singer B.U.K. Sewing Motor.
   THIS efficient motor has been specially designed
     for the operation of Singer Family SewingT
     Machines, its speed being at all times under
the perfect control of the operator.

    Instructions for Attaching the Motor.

   First remove the machine belt, then fix the motor,
by its supporting bracket, to the back of the machine
arm.
  To fit the bracket, remove the japan from the
edges of the tongue (A, Fig. 1) on the machine arm,
over which the slot in the motor bracket will fit.

This is necessary so that the bracket will slide up
and down freely.

  Place the motor bracket on the tongue, as shown
in Fig. 2, so that the hole (B, Fig. 1) in the centre
of the tongue can be seen through the slot (C, Fig. 2)
in the motor bracket; then insert the screw (D,
 Fig. 2) and, after moving the motor upwards as
 far as it will go, tighten the screw.

            Putting on Fabric Belt.
    Place the fabric belt over the top of the balance
  wheel into the groove at its back, as shown in Fig. 3,
  and then force it into the groove in the motor pulley,

  in the manner shown in Fig. 4. The latter is easily
  accomplished by placing the belt half over the motor
  pulley (E, Fig. 4) and holding it firmly in position

with the thumb and forefinger of the right hand;,
  • a slight turn of the balance wheel will then cause
  it to spring into position

5
       Regulating the Belt Tension.
  To adjust the belt tension, loosen the screw (D,
Fig. 5); this will allow the motor to drop down-
ward. Now firmly retighten the screw, and the
belt will be found to have the correct tension.

        Applying the Singerlight.
                   (See Fig. 6)

  Remove the screw (M, Fig. 6) which holds the
cover plate (P, Fig. 6) in position, and place the
ring bracket (N, Fig. 6) over the opening, having the
two small lugs (O, Fig. 6) in the position shown.
These lugs are intended to maintain the Singerlight
in the horizontal position. Place the cover plate
(P) over the ring bracket and insert the screw (M)
through the holes in both and into the hole in the
arm of the machine. Turn the cover plate down
to its normal position, and retighten the screw.

             Electrical Connections.

supplied fitted with flexible cords for making the

insulated thumb nuts (U, Fig. 8). It will be noticed
that the terminal block has three screw posts, and
that those to the outside have distinctive coloured
spots against them.
  The leads for the motor are coloured red and
black.The eyelet of the red lead should be placed
on the post nearest the red spot, and the eyelet of
the black lead on the centre post.
   Place the eyelet at the red end of the Singerlight
lead on the post nearest the red spot and the eyelet
of the yellow end on the post nearest the yellow
spot.

Replace the three thumb nuts (U), tightening the
latter securely ; then, with the screw (S), fasten the
terminal block to the motor bracket, as shown in
Fig. 7.

             Foot Controller.

  The foot controller. should be placed on the floor
in a convenient position for the user's right foot.



                   Speed.

  The speed of the machine is at all times under
perfect control. Pressure of the foot on the lever
of the foot control will set the machine in motion,
the speed being regulated by the amount of pressure
applied to the lever.
  Speeds varying from bare movement up to 1000
stitches per minute can be obtained, as required
by the work in hand. Immediately the pressure
on the lever is withdrawn, the machine will stop.
 It is not necessary to touch the balance wheel as
the machine will always start in the right direction.

11
         Embroidery and Darning.

   For embroidery and darning, the machine requires
  to be operated at a low speed. Light pressure of the
 foot on the foot control lever will set the machine
 in motion at a low speed suitable for the convenient
 handling of materials being darned or embroidered.

  To prepare the machine for this work, remove
 the presser foot and raise the presser bar. Then
 adjust the stitch-regulating screw, so that the feed
 will be inoperative.

    It is advisable that the throat plate be covered
 with the supplementary plate made for the purpose,
 and it is essential that an embroidery hoop be used
for clamping the material. The purpose of the
 latter is to keep the work taut and to permit of it
being conveniently moved backward and forward
and from side to side by hand between the stitches.

  Feed cover plates and wooden hoops can be
obtained at any Singer Shop or of any Singer sales-
man at small cost.

  Darning by machine, when well done, is almost
imperceptible. It is far stronger and better than
hand work, and is much more quickly executed.

        To Lubricate the Motor.
  When sent from the factory the motor is lubri-
cated sufficiently for approximately six months' use.
 A tube of Singer Motor Lubricant is furnished
with each outfit. This tube has a tip which will
 fit into the two lubricating holes (W.W., Fig. 10)
leading to the motor bearings.
  Never under any circumstances apply oil to
any part of the motor.   Singer Lubricant, which
 is specially compounded for use with Singer motors,
 will remain just where it is wanted in the motor
bearings, while oil would work its way into the com-
mutator and brushes, giving rise to considerable
 trouble and vexation, such as difficulty in starting,
 over-heating, smoking, etc.

13
          To Remove the Bulb.

   To remove the bulb, hold the Singerlight socket
  tightly with one hand, and with the other turn the
  shade half-way round until the pin in the socket is
  opposite the slot in the shade collar. Then gently
  pull the shade forward and allow it to hang free,
 as shown in Fig. 11.

                             Fig. 11.


   Press the bulb into the socket, and, at the same
time, turn it away from the machine until the bulb-
pin is out of the notch. Then withdraw the bulb
and shade.

14
         To Replace the Bulb.
  Pass the metal end of the bulb through the collar
of the shade, with the slot in the shade collar up-
ward.  Hold the socket tightly with one hand, and
with the other hand press the bulb into it, with the
bulb-pin in the slot of the socket. Next, turn it
towards the machine until this pin is in the notch ;
then slip the shade over the socket, with the socket-
pin in the slot of the shade collar. See that the
shade is pressed well home, so that the pin is
opposite the ridge in the shade collar. Then turn
the shade until it is at the top.

          To Light the Lamp.
  To obtain light, push the small knob on the top
 of the lamp over towards the lamp shade.
