DESCRIPTION
HIGH SPEED MACHINE 143G2 has an aluminium alloy vibrating
needle bar frame and a rotary hook, and is intended for over-
seaming and zigzag stitching on fine lingerie, general fabrics
and light weight leather. It has ball bearings on the rear end
of the arm shaft and hook drying shaft. The needle has a maxi
mum throw of 3/16 inch, vibrating both sides of a centre line.
The speed of this machine is especially valuable in zigzag
work and long overseaming in fine fabrics such as women's under
wear, slips, also reducing corsets, dresses, etc. It is success
fully used in general tailoring work and the manufacture of
articles such as trousers, coats, gloves, and for certain opera
tions in the manufacture of shoes, such as attaching side and top
facings to the linings and butting canvas or felt toe pieces to
the end of the vamp.
In the manufacture of table covers, draperies, scarfs, etc.,
an ornamental effect can be produced by overseaming a cord with
thread of a contrasting colour. The raw edges of fabric may be
overseamed by taking one stitch in the fabric and the other over
the edge.
MACHINE 143G3 is similar to Machine 143G2 except that the
needle has a maximum throw of 5/16 inch. It is designed for
basting and tacking coat pads.
Speed
The maiimuiD speed recommended for either machine Is 3000
stitches per minute, the speeds dep^dlng on the material being
sevc. The machines should be run slower than the maximum speed
at first until the parts which are In moving contact have become
glazed by their action on each other. When the machine Is In
operation, the machine pulley should turn over toward the oper
ator.

Needles
Needles for Machines 143G2 and 143G3 are Catalogue 1901
(l35x7), made In sizes 7,8,9,10,12,14,16,18,20,22 and 24.
The size of the needle to be used should be determined by the
size of the thread which roust pass freely through the eye of the
needle. If rough or uneven thread is used, or If It passes with
difficulty through the eye of the needle, the successful use of
the machine will be Interfered-with.
Orders for needles must specify the QUAWTITY required, the
Si;2! and also the Catalogue number.
The follovflng is an example of an intelligible orderi
"100 size U, Catalogue 1901 Needles".

To make a
smooth, even stitch with your sewing machine, use
good, firmly twisted and smoothly finished thread, that passes
freely through the eye of the needle.
From the library of: Superior Sewing Machine & Supply LLC

In using slack twist or uneven silk,should It be frayed or
roughened, see whether the needle Is too fine or too sharp, or
has ahooked point, made by striking the throat plate.
For ordinary work use the same size of thread on the bobbin
as In the needle. Always use soft finished thread on the bobbin.
Thread
Left twist thread should be used In the needle,
or left twist thread can be used In the bobbin.
Either right
Fig. 7. How to Determine the Twist
Hold the thread as shown above. Turn the thread over toward
you between the thumb and the forefinger of the right hand; If
left twist, the strands will wind tighter; If right twist, the
strands will unwind. Use soft finish thread of the same size for
the needle and the bobbin.
Fig. 8. Removing the Bobbin case
To Remove the Bobbin Case
Lift the bobbin case latch, as shown In Fig. 8, and draw the
bobbin case out from you, turn Its open end down and release the
latch and the bobbin will drop out.

To Wind the Bobbin
(See Fig. 9)
Fasten the bobbin winder to the table with its driving pulley
in front of the machine belt so that the pulley will drop away
from the belt when sufficient thread has been wound upon the
bobbin.
Fig. 9. Winding the Bobbin
Place the bobbin on the bobbin winder spindle and push it on
as far as it will go.
Pass the thread down through the thread guide (1) in the ten
sion bracket, aromd the back and between the tension discs (2).
Then wind the end of the thread around the bobbin a few times,
push the bobbin winder pulley over against the machine belt and
start the machine.
When sufficient thread has been wound upon the bobbin, the
bobbin winder will stop automatically.
If the thread does not wind evenly on the bobbin, loosen the
screw (a) in the tension bracket and move the bracket to the
right or left as may be required, then tighten the screw.
The amount of thread wound on the bobbin is regulated by the
screw (B). To wind more thread on the bobbin, turn the screw (B)
inwardly. To wind less thread on the bobbin, turn the screw out
wardly.
Bobbins can be wound while the machine is stitching.
