FWIW - - -

Most radio wire machines ran 24/7, as the radio wire was seldom dead - 
they ran 24/7.

The press service 6-level machines on the teletypesetter circuits would 
have motor controls, as the teletypesetter service usually had hours 
that would assure that all stories for consumption were sent well ahead 
of press time, and the machines did not have to run 24/7.

Commodity News Service machines had motor controls, as they were not 
watched 24/7, but when the commodites markets (pork bellies, cow 
tongues, and such) were watched during normal slaughter hours. This 
aided in watching labor costs as they did not have to run the kill 
systems after their days run was completed.
