TO OPERATE THE MACHINE

NEEDLES

1. Raise feeding foot A, Fig. 5 by moving lifter B

upward.

2. Place both feet upon the treadle.

3. Turn top of hand wheel over toward you to

start machine. (If hand wheel is fitted on front of

machine, turn top of hand wheel from left to

right to start machine.)

4. Allow the feet to move freely with the motion

of the treadle. Continue this motion with an

alternating pressure of heel and toe until a

regular easy movement is acquired and the

hand wheel is kept in continuous rotation by use

of the feet alone.

5. When familiar with the treadle movement, and

you are able to re-start the machine without

turning the hand wheel in the wrong direction,

place a piece of material under the feeding foot.

6. Lower feeding foot by lowering lifter and oper

ate machine until you have become accustomed

to guiding the material.

Material is moved along by the feeding foot only,

and, the direction of stitching can be changed as de

sired, by turning wings. Fig.32. To make a curved line

of stitching, operate machine slowly and, without

turning work, turn the revolving wings enough to pro

duce the desired curve.

Feeding foot rises between each stitch while needle

is in the material. With needle serving as pivot, ma

terial can be turned in any direction. When desired,

the feeding foot may be fixed to work in a straight

line, in any direction, by tightening the knurled screw

A, Fig. 22.

Never turn the work or alter the direction of the

feed while the foot is pressing on the material, as this

may cause missed stitches and damage the surface

of the work.

Needles for MACHINES 29K71, 29K72 and 29K73

are of Class and Variety 29 x 3 for cloth and 29 x 4

for leather. Needles 29 x 3 are made in sizes 11, 14,

16, 17, 18, 19, 21, 22, 23, 24 and 25, Needles 29 x 4

are made in sizes 9, 11, 14, 16, 18, 19, 21, 22, 23,

24 and 25.

The above needles regularly have nickel finish but

can be supplied with chromium finish if ordered.

The size of the needle to be used should be deter

mined by the size of the thread which must pass freely

through the eye of the needle. Rough or uneven thread,

or thread which passes with difficulty through the eye

of the needle will interfere with the successful use

of the machine.

Orders for needles must specify the Quantity re

quired, the Size number, also the Class and Variety

numbers separated by an x.

The following is an example of an intelligible order:

"100 No. 16, 29 X 3 Needles", for cloth.

"100 No. 16, 29 X 4 Needles", for leather.

The best stitching results will be obtained by using

the needles sold by Singer Sewing Machine Company.

THREAD

Left twist thread should be used in the needle.

Either right or left twist thread can be used for the

bobbin.

To determine the twist, hold the thread as shown.

Turn the thread over toward you between the thumb

and forefinger of the right hand; if left twist, the

strands will wind tighter. If right twist, the strands

will unwind.
