[GreenKeys] 1917 thesis on Morkrum

[dmm at lemur.com]

I've just stumbled upon a rather interesting, fairly early study.
It is a 1917 Bachelor's thesis submitted to the Armour Institute of
Technology (one of the predecessors of the Illinois Institute of
Technology by Ralph H. Earle.  The title is:

   "The Morkrum System of Printing Telegraphy"

It has been digitized, and is available online at The Internet Archive:

http://www.archive.org/details/morkrumsystemofp00earl

It is a study of the entire system of equipment.  It has a few
photographs, and a number of drawings.  It doesn't identify the
equipment by model/type number (the page printer shown has a
typewheel mechanism on a moving carriage, and a stationary (well,
rotating but otherwise stationary) platen.  I'd be curious to learn
what the model/type numbers were for the equipment shown.

If you're unfamiliar with The Internet Archive, the page link above
will take you to a general bibliographic page for the item.  On the
left there is a small box which lets you select any of a number of
formats, both for online viewing and downloading.  
If you're on Linux or another system with a nice file grabber such
as wget, it may be convenient to go to the "All Files: HTTP" link,
which gives you a directory of all of the file formats.
The most easily viewable formats are of course PDF and DejaView
(if you have a DejaView viewer installed; it's really quite a nice
format).  You can, as well, download the original images scans
(which are, of course, large).

I apologize if this volume is something that everyone already knows
about.  I'm still very, very new to TTY, and am just discovering the
basic sources.
