INTRODUCTION

A

wire stitcher, like

any

other machine,

will

give

satisfactory

results

to its

owner only

if

properly

installed,

regularly

lubricated,

intelligently adjusted,

and

carefully maintained. Moving parts will wear

in

time

and

require replacement, while others

may

break

through

accident.

Trained

service

men are

available

but not

always

to be had at a

moment's

notice,

and a

knowledgeof

thefunctionsof

themore

important parts

of a

stitcher

is

therefore most

desirable

for

every person responsible

for its

operation,

in

order

to

know what

to do in

case

of

trouble.

We

have, therefore, gathered together

the

com-

bined

experience

of our

engineers

and

service

men

and

have attempted

to

present

the

information

in a

manner

that

will

make

it

quickly available

and

readily

understood.

We

would urge, however,

in any

case

of

serious

difficulty that

you

notify

our

nearest sales office,

sending samples

of the

defective work

and

describ-

ing the

trouble

in

detail,

so as to

obtain

the

benefit

of

their experience

in

arriving

at the

proper solution.

Be

sure

to

report

the

serial number

and

model

of the

machine when corresponding

in

regard

to

equip-

ment,

so

that

it may be

identified quickly.

2.

INSTALLATION

(See

charts

and

parts lists

for

locations

and

names

of

parts referred to.)

Any

machine

can be

seriously damaged during

its

installation

if it is not

properly

set up;

therefore,

we

recommend close adherence

to the

following

procedure:

(a)

After

uncrating

machine,

examine carefully

for

any

breakage

in

transit.

If

such

be

found,

do not

attempt

to run

machine

but

report

at

once

to the

selling agent.

If our

service

man is

present,

let him

examine

machine

and

then report

to the

manufac-

turer.

(b) See

that motor

is

free

to

revolve

when

large

pulley

or

flywheel

is

turned

by

hand.

If

tight,

clutch

is

perhaps

engaged,

in

which case shaft

will

turn

also.

Turning pulley

or

flywheel

one

revolution

will

release

clutch.

(c)

Examine name plate

on

motor

and see

that

its

specifications

are the

same

as

those

of the

power

to

be

used.

If

not,

do not

attempt

to

operate

the

machine.

(d)

Place

the

machine

on a

level

floor,

using

shims

under base

if

necessary

to

prevent

any

movement

or

rocking.

(e)

Lower clincher

to

at

least

2"

below

the

stitcher

head,

by

means

of

adjusting sleeve

on

post type

stitcher,

orclincherbracketadjustingscrewon

type stitcher.

(f)

Be

sure

that

the

machine

isoiledthoroughlyat

all

points before operating.
Run a little

oil on

coil

of

wire,

which

helps

to

lubricate

wire feed tubes

and

also

the

formers

and

driver,

which

are

tight-fitting when new.

Tie a

piece

of

cloth temporarily around

the

wire above

the top

end

OT

tne

upper wire

Teed

tube

to

remove

dirt

and

excess

oil and

thus prevent soiling

the

work.

(g)

Connect motor cord

to

power outlet

and

start

motor.

See

that

it

runs freely, without

undue

noise,

and

that

the

large pulley

rotates

clockwiseasviewed

from

the

front

of the

machine. Should

it

rotate

counter-clockwise, motor

wiring

should

be re-

connected

by an

electrician

in

order

to

reverse

direction

of

rotation.

(h)

Push down foot switch treadle

and

thus start

machine operating, starting

and

stopping several

times.

(i)

Stop motor,

and

with

connecting link

arm

pulled down, turn pulley

by

hand until

driver

is at

lowest

point.

(j)

With driver

in

lowest position

and

work

to be

stitched

under same, raise clincher post, bracket,

or

arm,

until work

is

held firmly. Then lock post,

bracket,

or

arm,

in

position.

.(k)

Place a spool

of

wire

of

proper

size

on the

spoolholder,

the

wire leading

to the

left

from

top of

spool, then tighten

spool-holderspindlejam

nut

just

enough

to

give a slight drag

to the

rotation

of

spool

and

prevent

the

wire

uncoiling.

If

it is too

tight,

the

wire

will

bind

and

catch

between

the

coils

and

thus

may

cause uneven

staple

legs.

If too

loose,

the

spool

may

unwind, causing

snags

in the

wire.

Cut

binding

wires

on

wire

coil

and

bend same

back

over edge

of

spool,

holding

free

end of

wire

in

the

hand

to

prevent unwinding

and

tangling.

Cut off

bent

and

twisted

end of the

wire, then straighten

out

about

6". The end of the

wire

to be

inserted

in

machine must

be

just

as

straight

as

possible.

Open wire feed gears

by

raising idler feed gear

throwout handle

and

insert

end of

wire through

eye

on

upper

end of the

spring

wire

guide. Enter

the

end

of

the

wire into

the

upper

wire tube, push down

between

the

wire feed gears, then through

the

lower

wire tube

and

between

wire

straightener

rolls. Push

it

into

the

hole

in the

stationary cutter, raising

the

end of the

wire slightly

if

necessary

for

proper

entrance,

then turn

down

the

idler feed gear

throwout handle, thus engaging

the

feed gears.

WARNING:—NEVER

OPERATE MACHINE WITH

WIRE

FEEDING

AND NO

MATERIAL

ABOVE

CLINCHER. SERIOUS DAMAGE

MAY

RESULT.

(I)

Start motor

and

drive

a few

stitches into

material and,

if

necessary, adjust clincher height

to

get

desired tightness

of

clinching.

See

instructions

for

adjusting clincher.

(m)

Adjust

for

proper length

of

wire

by

loosening

lock screw

and

moving wire feed guard casting

to

rightor

left

along gauge marks

on

upper

part

of

head

casting. Moving

to

left reduces wire draw while

moving

to

right increases

it.

When

set at

mark "0",

head

will

draw

one

inch

of

wire

and

each mark

indicates

an

additional 1/8"

in

length. When proper

length

of

wire

is

being drawn, tighten lock screw

in

place firmly.

(n)

Drive several rows

of

stitches into material

to

be

used, examining crown

and

legs

for

proper

appearance.

If not

satisfactory, adjust machine

in

accordance with directions given hereafter.

NOTE:—When

changing length

of

wire draw,

the

first stitch

driven,

and

perhaps

the

second,

will

beof

the

previously used

length

since

it is

formed from

a

piece

of

wire already

cut and

held

in the

anvil.

The

third

stitch,

however,

will

be of the new

length.

(c)

Stitching

Wire

When

stitching

metal

it has

been found

that

#18

wire

is

best suited

to the

majority

of

work. This

wire

can be had in

various

degrees

of

hardness

or

temper,

such

as #18

Bookbinders wire, which

is the

softest,

#18-230, #18-260, #18-290

and

#18-330.

It

is

impossibletogivethe

exact

thickness

of

metal

which a given temper

of

wire will penetrate.
Roughly, Bookbinders wire will penetrate a single
thickness

of

.020 soft steel;

#18-230,

two

thicknesses

of

.020 (total

.040);

#18-260,

two

thicknesses

of

.040

(total .080); #18-290,

one

thickness

of

.060 plus .030

(total

.090); #18-330

two

thicknesses

of

.060 (total

.120).

If

the

metal

is too

hard, there

may be

trouble

in

stitching

so

great a thickness;

on the

other hand,

if

the

metal

is

soft,

the

thickness

may be

increased.

When stitching a soft material like fibre

or

rubber

to

metal,

especially

if

this material

is

thick, there

may

be

trouble

in

penetrating

the

metal

due to

lack

of

support

for the

wire

in the

soft material.

For

this

purpose,

the

#18-290 wire

may

help,

in

which

case

special

spool

holder

equipment will

be

required.

It is

best

to use the

softest wire that will penetrate

the

work safely,

as the

harder wire will cause more

wear

on the

machine.
