[GreenKeys] Teletype model 15 article

[Larry Rice]

=46ellow Greenkeyers,

I'm the editor of a club newsletter sent out to ex-telegraphists
and I'm writing down a few notes for a future article about the
introduction of the Teletype model 15 into Australia. If any
Greenkeyer has any trivia about the machine, humorous, "well I
never!", statistical content, or  correcting any data I've
written, I'd be grateful to receive it.  eg. anyone know the
weight of one?
Thanks chaps.   Larry Rice=20

These are the notes I have so far:-=20
(bear in mind it's written for Australian readers).

=46ollowing up the Merredin article in the last issue, MZ eventually
lost their morse circuits in May 1960, its replacement was a large
black box which was otherwise known as a Teletype Model 15. This
was a heavy duty printer which commenced volume production in 1930
until 1954 by the Teletype Corp. of Chicago U.S.A.=20

By the 1950=92s, the teleprinter was the main telegraph terminal
device in use in the telegram service.=20

Alongside morse equipment prior to World War 2, Creed
teleprinters were installed when the traffic warranted it, e.g.,
even in the 1930=92s, the No. 17 line was teleprinter equipped to
=46remantle. =20
The Creed factory had difficulty in maintaining exports early in
World War 2 due to the British war effort so when the U.S. Army=20
arrived in the early 1940=92s,  they considered Australia=92s
communications =92backward=92 and promptly brought in their own
equipment. The PMG acquired its own Teletype teleprinters as war
surplus from the departing U.S. Army, still labelled 'U.S. Defense
Department' on the inside and later the machines were purchased
direct from the United States. =20

=46rank Bailey from the Sydney Telegraph Subscriber Maintenance
Department recalled the early days of the Teletype.=20
'They were treated like babies in those days. They were stripped
down every six months and examined for wear,' he said. 'They were
built to last just like a fine watch', he added.

A striking example of mechanical simplicity versus mechanical
complex:=20
1) There were 2 moving parts needed for a morse circuit:=20
One for the pivot of the morse key and one for the armature of the
sounder.
2) There are about 486 parts in a Teletype model 15.

Some reckon as long as they were properly serviced and maintained,
they could still be chugging out commercial copy today if
technology had not overtaken them.

When the Teleprinter Reperforator Switching System (TRESS) was
introduced in 1959, telegs may recall the Number Bulletin printer
was a Teletype 15.=20
