Teletype Model 28 KSR
Typing Unit
The typing unit is by far the most mechanically interesting part of the Teletype, due to the sheer number of functions it contains and the complexity of decoding a 5-bit serial word into a type box position. It contains a main shaft with no fewer than six clutches controlling various functions as well as a secondary drive shaft at a right angle to the first that transfers power to the mechanism that moves the printing carriage. The bulk of the complexity in terms of parts count is divided between the decoding mechanism and the type box positioning mechanism, with the remainder of the TU being relatively simpler.
The structure of the typing unit is provided by two sheet metal frame pieces, one on each end of the unit, and a number of functional structures and support rods that spread between those frames. It is held to the keyboard unit by four screws, and removing these four screws allows it to be lifted out of the Teletype machine as an assembly for maintenance or repair. The keyboard is non-functional with the typing unit removed, as drive power for the keyboard is transferred through the drive shaft of the typing unit.
The main shaft of the typing unit is readily visible from the bottom. Power is transferred into the unit from the motor output gears via a large nylon gear. The rotational speed of this shaft sets the timings for everything in the unit, so the gearing between the 3600 RPM motor and the nylon drive gear on the main shaft in the typing unit determines the rate of the unit. For 60 WPM (as used in Amateur service), the main shaft of the typing unit rotates at 368 RPM. The keyboard unit is driven from the main shaft of the typing unit at a right angle by a helical gear, such that the keyboard unit and typing unit operate at the same speed. Power for the carriage mechanism is also taken off the main shaft at a right angle via helical gears to the spacing shaft.
A series of six normally-open clutches ride on the main shaft, each one engaging for 1/3, 1/2, or one full rotation when tripped. One full rotation of the main shaft corresponds to a single character decode, so no single operation driven by this shaft requires more than one rotation to complete.
Incoming signals pass into a selector magnet assembly on the right-hand side of the typing unit (all references to position are from the operator’s seat point of view) just behind the carriage mechanism. The armature on that assembly depresses or does not depress a series of levers that are pushed one at a time by a series of rotating cams, depending on whether the signal line holds a mark or a space at that instant in time. The rotating cams are on a clutch on the main drive shaft that is released by the start bit and that rotates exactly once per incoming character, triggering each bit lever in turn. These levers set up a bank of bars that run the width of the typing unit and are used to locate the type box for the hammer strike at the end of the character.

CHAPTER 12
The highways to the park were wide and comfortable to drive on, and the signs easy to follow even for those who didn't speak Spanish. About the only hazards were the huge tourist buses, which moved along at over 150 kilometers per hour, like land-bound ocean liners, their windows full of people, many of them children who waved down at the drivers of the passenger cars. The drivers waved back with smiles of their own, and allowed the buses to plow on, exceeding the speed limit as though it were their right to do so, which the car drivers didn't want to risk. They had plenty of time. They'd planned their mission that way.
Tomlinson reached down to his left leg and grimaced. Chavez dropped back from the morning run to make sure he was okay.
"Still hurts?"
"Like a son of a bitch," Sergeant Tomlinson confirmed. "So go easier on it, you dumb bastard. The Achilles is bad thing to hurt."
"Just found that one out, Ding." Tomlinson slowed down to a walk, still favoring the left leg after running over two miles on it. His breathing was far heavier than usual, but pain was always a bad thing for the endurance.
"See Doc Bellow?"
"Yeah, but ain't nothing he can do 'cept let it heal, he says."
"So, let it heal. That's an order, George. No more running until it stops hurting so much. 'Kay?"
"Yes, sir," Sergeant Tomlinson agreed. "I can still deploy if you need me."
"I know that, George. See you in the shooting house."
"Right." Tomlinson watched his leader speed up to rejoin the rest of Team-2. It hurt his pride that he wasn't keeping up. He'd never allowed any sort of injury to slow him down-in Delta Force he'd kept up with the training despite two broken ribs, hadn't even told the medics about it for fear of being thought a pussy by the rest of his team. But while you could conceal and gut out bad ribs, a stretched tendon was something you couldn't run on - the pain was just so bad that the leg stopped working right, and it was hard to stand up straight. Damn, the soldier thought, can't let the rest of the team down. He'd never been second-best in anything in his life, back to Little League baseball, where he'd played shortstop. But today instead of running the rest of the way, he walked, trying to maintain a military one-hundred-twenty steps per minute, and even that hurt, but not enough to make him stop. Team-1 was out running also, and they went past him, even Sam Houston with his bad knee, limping as he ran past with a wave. The pride in this unit was really something. Tomlinson had been a special-ops trooper for six years, a former Green Beret drafted into Delta, now almost a college graduate with a major in psychology - that was the field special-ops people tended to adopt for some reason or other - and was trying to figure out how to complete his studies in England, where the universities worked differently, and where it was a little unusual for enlisted soldiers to have parchment degrees. But in Delta they often sat around and talked about the terrorists they were supposed to deal with, what made them tick, because in understanding that came the ability to predict their actions and weaknesses-the easier to kill them, which was the job, after all.
