a

small

rod

inside

the

Key

which

in

turn

transmits

motion

to

the

Segment

Release

Mechanism

andtothe

Zero

so

that

it

moves

out

from

under

the

Selection

the

Segment

actuated

by

a

spring,

is

stopped

by

the

Number

Pin.

Again

the

Multipliex

and

depress

the

Numeral

Key;

and

note

that

the

small

the

Key

also

actuates

the

Escape-

ment

Pawl

downward

until

the

Holding

Pawl

moves

out

of

a

Tooth

in

the

Escapement

Bracket.

As

the

Key

is

released,

the

Multiplier

Selection

Unit

is

allowed

ta

move

to

the

left

the

space

of

one

Tooth,

We

have

now

completed

the

Selection

of

the

Num-

her

Linthe

Multiplier

Selection

Unit.

This

places

the

Multiplier

1

in

the

first

column

of

the

Multi-

plier

Unit.

Depress

the

Numeral

2

and

note

that

the

Unit

has

now

moved

to

the

second

position,

and

the

first

number

selected

has

now

been

placed

in

the

second

colurnn

of

the

Multiplier.

As

each

digit

of

the

Multiplier

is

selected,

the

column

position

of

the

previous

digits

moves

one

space

to

the

left.

Thisis

easily

séenqnacovered

ma-

chine

by

noting

the

numeral

on

the

Decimal

Point~

er

Bar

in

line

with

the

first

number

selected;

thus,

if

you

depress

the

|

Key

three

times,

the

first

1

selected

will

be

in

line

with

the

figure

3

on

the

Decimal

Pointer

Bar.

Thus,

whenyou

se-

lect

a

Multiplier

in

the

Multiplier

Key

Board,

you

would

put

it

in

as

you

would

read

it;

that

is,

for the

Multiplier

125,

you

would

depress

the

1,

then

the

2,

and

then

the

5.

GENERAL:

The

foregoing

descriptive

drawings

and

text

are

merely

an

effort

to

start

you

on

your

way

toa

fuller

understanding

of

the

Friden

Calen-

lating

Machine.

Apply

these

principles

to

other

HOW

MACHINE

operations;

trace

these

operations

through

the

machine

so

you

will

KNOW

what

is

taking

place

in

your

machine

when

any

one

of

the

Control

Keys

isdepressed.

After

youhave

masteredthis

phase

of

the

work,

there

should

be

little

ta

bother

you

in

making

accurate

diagnosis

of

machine

troubles

and

locating

the

proper

part

or

place

to

make

correction.

When

making

corrections

in

adjustments,

and

in

particular

in

the

case

of

Sequence

Adjustments,

be

SURE

to

follow

the

line

of

adjustments

all

the

way

through

to

determine

where

adjustment

or

correctionis

needed.

Many

times

machine

trou-

bles

are

multiplied

when

the

mechanic

starts

making

adjustments

without

first

determining

WHERE

correctionisneeded.

Make

sure

of

your

diagnosis

before

doing

anything

to

a

machine;

your

corrections

will

be

far

easier,

more

effi-

cient

and

quicker.
