[GreenKeys] Kleinschmidt Type Wheel

[Steve Garrison]

That style of typewheel was introduced a good while before 1965, I'd guess
more than 10 years earlier, and is in the M28 reperfs as well.

 

I trained on them in early 1966 and if they had just been recently
introduced I would not have been seeing them everywhere in the comm centers
I worked.

All;

 

Based on dates in Army FM it appears that the introduction/use of the
Kleinschmidt type wheel (ca. 1965), instead of the standard type-basket seen
in typewriters and Teletype M14/15/19 equipment, follows the introduction by
IBM of the "golfball" typewriter mechanism (1961), and predates mechanisms
like the daisy wheel (Diablo, 1970) and spinwriter (NEC, 1977).

 

How far off-the-mark am I in that statement?  Would anyone care to elaborate
on the why's and wherefores regarding types of printing mechanisms in the GK
repertoire?  (Yes, to include the "type pallet" design :->.)

 

I'm curious.  The Kleinschmidt type wheel seems to have the type-basket
approach beat hands-down, at least in the restrictive context of a
tape-printer mechanism.

 

Thank you,

paul
