TIMEGRAPHER MODEL P-61

IMPORTANT

FEATURES

:

1.

Extra

small

and

lightweight:

Made

light

for

portability.

Occupies

little

space,

and

is

easy

to

carry.

2.

High

efficiency

:

Further

technical

improvements

have

been

made

due

to

our

long

experience

and

continuing

research.

3.

Carrying

case

unnecessary

:

The

machine

case

is

also

a

carrying

case

.

4.

Stand

microphone

:

By

changing

the

position

of

the

milk,

it

is

possible

to

change

the

position

of

the

watch

being

tested.

5.

Easy

operation

:

Starting

has

been

further

simplified.

Operation

is so

easy

that

even

a

layman

can

use

it

.

PRINCIPLE

AND

CONSTRUCTION

The

use

of

a

highly

efficient

quartz

crystal

ploys

on

important

role

in the "

TJME

-

GRAPHER" . The

exacting

signal

standard

obtained

from

use

of

the crystal,

is

compared

with

the ticks

of

the

watch

and

the result

is

recorded

. Thus

on

accurate

test

of

the w

at

ch

IS possible.

The

frequency

of

the crystal

is

5,280

cycles (5,280

vibrations

per

second),

and

th

is

frequency

is

reduced

to

60

cycles to

synchronize

with

the

moto

r. The

motor

turns the

spiral

roller

(

wtth

2

projections

)

at

a speed

of

15

rev.

or

16

.5

rev

.

per

second (

change

being

mode

by the crystal selector switch).

The tick

of

the

watch

acti

vates the

printing

bar

,

and

records the

difference

as com-

pared

with

the

frequenc

y

standard

time by

striking

the

projection

of

the spiral

rol

ler, as

in the

Use

of

Earphone :

When

using

earphone

, lift

up

ba

r

of

paper

feed

,

and

stop

the

printing

sound.

and

it

is

easy

to

hear.

Turn

knob

(H)

to

right

and

the

tick

becomes

louder.

By

using

the

earphone

,

the

following

can

be

detected

:

( 1)

touching

sounds

of

hair

spnngs

.

( 2)

unnatural

sound

caused

by

damaged

balance

staff

and

jewel

hole.

( 3)

irregular

so

und

caused

by

improper

meshing

of

gears

of

the

pallet

fo

rk

&

staff

.

( 4)

when

the

balance

with

hairspring

touches

other

parts

and

creates

sounds

.

( 5)

touching

sounds

of

pallet

fork &

staff

and

roller

table.

As

above

, by

using

the

earphone

one

con

find

cause

of

trouble

which

were

never

before

recognized,

such

as

defects

detected

in

the

process

of

changing

the

p

os

ition

of

the

watch

,

which

are

not

re

c

orded

on

the

Non-drying

ink

has

been

us

ed

which

has

, by a

special

method

,

impregnated

deepl

y

into

the

sponge

-like

roller

( W

),

so

that

it will

withstand

long

use.

However

,

if

it s

hould

become

nece

s

sar

y,

apply

a small

amount

of

the

spore

ink

over

the

ro ller with

a

brush

( j

).

Stop

roller

when

inking

and

use

ink

sparingly

.

New

rollers

ma

y

be

obtained

from

us.

Do

not

use

stamp

RECORDINGS

I Principle

of

Recording

The

recording

paper

IS

fed

by

a

paper

feed

roller

(h)

under

the

spiral

roller

at

a fixed

speed

where

the

printing

bar

strikes

the

spiral roller.

When

the

watch

is

faster

than

the

fixed

speed

of

the

revolution of

the

roller,

the

recorded

line

ap·

pears

at

an

inclination

towards

the

right, which

means

that

there

is

a

"gain"

1n

time,

and

the

reverse

recording

shows

a

"lose"

of

time.
