Attempts were made with the models 32 and 33 to produce a reasonably reliable but simpler mechanism which could operate at the same speed- this uses a type cylinder rather than a type bar. However, this proved not to be as reliable, and the Model 35 was made using similar mechanics to the Model 28.
The Model 28, along with the 32, 33 and 35 are the fastest machines Teletype made. The Model 28 (shown here) and the Model 35 use a type box which is carried on a shuttle moved around by levers and cables. Special care was given to the shuttle which carries the type box to ensure that it was as light as possible without sacrificing rigidity.
I use to install and work on these things back in the late 70's early 80's along with the Model 33, 35 and 40, I can still take one of these things apart right from the face plate down to the main shaft and all of the cluthes and lets not forget the stunt box where all of the function bars resided,
In the 60s I was running the ground station for Tacamo flights. The Tacamo Planes (Hercules) would fly out over the Gulf and deploy a 7 mile long trailing
antenna (Honest) They had a very powerful VLF transmitter. I had a Model
28ASR and I sent Quick Brown Fox to them on HF. they relayed it back to me
Toured the USS Turner Joy in Bremerton, WA. The radio room is normally locked off, but they let me in. The TTY's are all still there, along with the rest of the radio gear. Go take the tour if you ever get the chance!
I was a teletype technician in the AIr Force 66-70 in the Air Force and 70-74 for RCA .. Model 19's, 28',s 33's, 35's, & Kleinshmidts .. that brought memories back for me as well. At my first base after tech school, Seymour Johnson, my trainer gave me a box full of 28 parts and said 'make it work.' I did
Dang, where can I get one of these? I'll bet when they were first introduced, some old timer said, "Why do we need one of these fancy machines? We have the Pony Express!"
When a teletype was sent overhauled/repaired it had to have a minimum of 72 points of range at 35 percent distortion. Those parameters also had to be met at an insurv inspection. I repaired them for 15 years in the USN and one year at a shipyard that overhauled them.. To learn how to fix them is easier then you would think. You learn all the sub assemblys's Then how they all work together. Trivia the clutch's on the tty are exactly the same as drum brakes on a car
MSTLOM - The head of the TTY school at Sheppard while you were there was probably MSgt Hill. I served under him at Hahn AB.
I originally trained on DSTE, but helped replace it with SRT after I arrived at Hahn. I then cross-trained into Teletype, working on M-28s and Teleautowriters.
The story I heard several times was that the M-28 had more moving parts than an F-4 Phantom II.
I was trained in the USAF at Sheppard AFB back in 1987 on the Model 28ASR. Most the M-28 was easy to learn and understand the the engineering of. But the Printing Unit was what blew my mind. I mean, there is heck of alot going on to print one character! After Sheppard I was sent to Vandenberg AFB and was trained on the Standard Remote Terminal.
I used similar machine when working for Tropical Radio-Telegraph Company in New Orleans. Don't know how they work, can't fix them, but I love being around them!
I don't know why... something about the way they look, the grey color, and the sound they make.
I used to take naps with my head resting against one of those machines. When a message came in, it would wake me up!
Brings back memories of my old model 19 and my model 28 ksr with Hal ST-5 interfaced to my Central Electronics 100V transmitter and my old R-390 receiver. my first machine was an old 1B that was a tape reader and I had to remove the tape from the machine, then stick it to a piece of paper if I wanted to keep a copy. Funny now but at the time I wanted a Drake "C line". but now I'd trade my "C line" for that old 100v and R-390. LOL
My father was a teletype operator for United Press International in Albany N.Y. then at Washington D.C. from 1951 to 1991 (40 1/2 years), until he got laid off. During my childhood, I got to go with him on the weekends and I went to the Smithsonian museums and we played co-ed softball with other news companies across the street from the White House in the ellipse park. Those were some fun days.
Once a col. complained to my husband that his copy of a message was blurred and commanded my husband (NCOIC of the Com. Cntr.) to change the carbon paper. So, my husband unrolled an entire length of the big roll of teletype paper, using headquarter's main hallway to do this. The thing unrolled right past the general's office (Gen. Caldwell [maybe related to the present Gen. Caldwell]).
"Bert!" yelled the general "What do you think you're doing?". "Colonel's orders, Sir".
Neat! I was once a teletype operator when stationed with the 5th Region Air Defense Command @ Fort Sheridan, IL. My MOS was 722.10; the NCOIC of the Crypto Cntr. is now my husband of fifty years. Does this punch out tape that can then be fed back in? Thanks for posting.
This is a 28KSR that doesn't have the tape perf. or reader. I have a model 28ASR that needs some work that has two tape perfs and a reader. I'll post a video as soon as I have it running. I also have another video of a 35ASR that shows it cutting a tape and reading it back in.
Spinning disk on end of motor houseing had three circular timing dots spaced equidistant around the circumference. Appropriate Tuning Fork was struck and sighted through. When motor was timed correctly, spinning timing dots appeared to be stationary while sighting through vibrating Tuning Fork. Speed was adjusted via button in the center of spinning disk. An accoustic version of mechanics strobe timing light. Hope this helps.
I bought it on the e-place for $50 plus a 200+ mile drive. The guy was about to throw it in a dumpster because he had it posted locally for a year with no takers. I hate to see such an incredible piece of engineering go to the dump.
I worked on these at the Spangdahlem AB (1984-86) in the weather station and base ops, and did ASRs there as well. We also had a few Kleinschmidts, and Telautowriters (DY-2, I think). I worked on ASRs for a few years in the 5th Combat Comm (1986-1989).
Maintained Klienschmidt machines also. Very dependable, Robust, and simple to repair. Adjusted motor speed with tuning fork. There was also a "minaturized" TTY Machine called a AN-TCC-14 or something like that. If it was not the keyboard contacts or something simple, could be difficult to repair in the field. I vaguely remember a FSK converter; I believe it was called a TH-5. Not sure, it's been a few decades. Also maintained Crypto Equipment. Thank you.
There was a ST-5 converter that was featured in "Ham Radio" magazine, I believe. It used CMOS Op Amps and could be built on a small (4" x 5") circuit board. I built and used some of these and have a couple PC boards in the junk box. They worked fine (for that vintage and simplicity).
I haven't heard that sound since 1972! Good grief, what memories that brought back from Sheppard AFB (1969), Kwangju AFB (1970-1971), and Wurtsmith AFB (1971-1972).
Does anyone have any of the old maintenance manuals from tech school? Remember the Klienschmidt? That was something else!
Superb Machine, maintained them in the Miliatary. Low Level models also. If you have one around with the tape perforator and reader, pop the hood on it and show the Folks some serious mechanical engineering. Brings back memories. Thank you.
I do have the military version of the 28ASR with two tape perforators and a tape reader. Once I have it cleaned up I'll make some videos of it. I have a 35ASR running right now that I'll probably make some videos of. I also want to create another one of this teletype running at a slower speed -- I think that will make it easier to see the incredible mechanics involved.
I'm running a program called Heavy Metal on the PC that this teletype is connected to. Heavy Metal lets you print news reports, TTY art and even read and send e-mail from the teletype.
