Today's picture is from 1908, and shows a man operating a Printing Telegraph. The device looks like it is something of an early version of a teletype. I found the conversation yesterday about Ticker Tapes very interesting, but will admit I was a bit confused, as the conversation began to center on Telex . . . is that the same thing as a ticker tape?Thursday, March 4, 2010

WOW, that sure looks like a lot of things to mess with for one telegraph.
ReplyDeleteIt looks like there are 36 butons on that face plate, I suppose one for every letter, and 10 numbers.
Yes, that was what was confusing me also.
ReplyDeleteYou post a photo of a ticker tape machine, and the next thing you know, people were talking about telex machine.
And the explanation were very confusing if your mind was thinking about ticker tape machine.

This link describes telegraphy (communicating at distance by use of code) with descriptions of morse code and telex. Both telex and morse code could be sent via either wire or radio.

The old telex machines I learned to use in the 90's were like this: http://tinyurl.com/ykntrj6
The segué to telex was natural.
ReplyDeleteTicker tape is the printout of a ticker machine which is a receiving device. Where did the data come from? Telegraphy!

This is a telex machine bank, which is similar to what I learned to use in the 90's. (The machines are very sturdy indeed! I think a few are still stored in some of our facilities they are 70's vintage.)

They are all evolving means of communication that resolve into the computers we use today, really. The ticker tape received and printed messages in a single line on a spool of paper. Early software programs were similar in that they were a single line on a spool of paper, but they were punches.
ReplyDeleteIt would be nice if PJM would correct the header. It's Telegraph.
ReplyDeleteJust think, data storage and transmittal started with the jacquard loom. http://www.makingthemodernworld.org.uk/icons_of_invention/technology/1820-1880/IC.031/
The spinning and weaving industry would also be an interesting topic for OPOD.
Wait a minute... what's that guy doing with the scissors?
ReplyDeleteJoe in NC: That's a novel coming over the telegraph. He's cutting to the chase. I kill myself.
