TELETYPE MODEL 15 KSR - COPYING ITTY - MUSEUM OF COMMUNICATIONS, SEATTLE

This is the last Model 15 KSR in service (PNB) on the Transmountain Pipeline. It began its service in
the mid 1930s and ran until 1984. Does it get a 50 year service pin?

Sadly my old 15 got moved out into the barn when the PCs took over. Bought it in 1972 at the Ft Wayne, Indiana hamfest for my ham radio station. My baby boy used to get the biggest kick when the bell would ring. Thanks for the video, ...music to MY ears!

WOWEE.... My dad was a telegraph operator for the Missouri Pacific for 28yrs. His office was just full of these teletype machines up until 1969 or '70. As a kid, i was mesmerized by the machinery and sounds. You had to SHOUT to be heard in his office area. Up until that time, there was still the wooden sounder-box for the telegraph key messages, btw. THANK YOU so much for posting this video. Wunderful ! I recall he used to complain about 'wire thieves' along the tracks too! All Aboard!

@douro20 The horizontal bars are called vanes and are positioned by sword shaped levers in the selector magnet area. I don't remember which position is 1 or 0. The bell crank levers glide along the vanes and position the crescent shaped notched bars on the carriage. A selected pull bar will fall into aligned notches and become operated by the pull bar bale. The pull bar is geared to a type bar and a character will then be printed.

amazing...

As I understand it, the horizontal bars are solenoid driven and carry commands to the printing mechanism in Baudot code. Am I correct to assume that an upwards position represents a '1' and a downwards position represents a '0' or is it the other way around?

A lot of people who own teletypes use them with a current-loop translator connected to a PC...

When I worked at a radio station years ago I love to hang around the news room listening to these things. There was just something hypnotic about their rhythmic clacking. I even like the unique smell of the ink and oil. Then they took these out and replaced them with much smaller machines that used some sort of dot-matrix print head. They just made little grunting sounds like a ginny pig. Life was never the same after that. :-(

As a longtime radio and TV guy ... I sure miss that sound!

And you would occasionally come in in the morning and find that the paper had jammed, filling the cabinet with an incredible amount of ink soaked paper shreds...but the motor still churning on...although too hot to touch.
