Hi James. Welcome to the list. This is a great group of people who are always willing to help. 

I just checked out your page on qrz.com.  Fantastic. I loved the pumpkin. 

73,

In 1928, they shortened their name to the Teletype Corporation. The 2-B was designed for Western Union for their Telegram service. The 2-B printed on gummed tape which was then pasted onto the Telegram message blank. The advantage of printing the message on tape instead of directly on the message blank was that if some of the message was garbled, only part of the message needed to be resent. Then they could "cut & paste" the correction. Also they did not have to waste time sending carriage return and line feed commands that would be required on a page printer. WU was very interested in maximum efficiency in sending messages.

The signalling system runs on a 60 ma loop, the same as the telegraph did. You will need a DC power supply of 50-150 VDC, current limited to 60 ma. This is a current-operated device, so the current is more important than the voltage. If there is a keyboard, it can be wired in series with the selector magnets (the big solenoids on the top).  The selector magnets are what converts the current pulses into mechanical motion to select the proper type pallet to strike the paper tape.

I have been helping clean out the home of a dear friend who passed away suddenly a few months ago and I came across a Western Union Simplex Printer 2-B (which looks like some kind of teletype machine?) and a Northern Radio Company Diversity Converter type 174. I put these aside from going to the scrap metal / recycling pile as they may have some value to someone.
