[GreenKeys] Hughes Printing Telegraph

[W2HX]

Here are more pictures.  I have a basic understanding of how the machine
works having played with it for several hours today.  Also, I found the
following document that describes EXACTLY this machine.  Even the photo
(fig. 1) is my machine exactly. There was some discussion back when the
machine first surfaced whether or not this was a Hughes, Siemens or Groos &
Graf (Gross & Graf).  I am convinced this is a Hughes based on this PDF.  I
will add that I believe Groos and Graf were contract manufacturers probably
building this for Hughes. Siemens did create an improvement over the weight
driven Hughes system using a motor (46 VDC) and the regulator (governor)
tower and some other improvements which is why their name is shown on the
regulator tower. (From The Worldwide History of Telecommunications By Anton
A. Huurdeman)

Although I didn't post any pictures, it is clear that my unit was once
weight driven but had been converted at some time.  On the cast iron base,
there is a pivot for the pedal (to pull up the weight again). Also there are
large holes in the ebonized base to allow for the rope? Cable? to feed
through.

More to come!

Hi all, I wanted to thank John Nagle for pointing out that Hughes printing
telegraph that was on auction in Germany.  I was able to negotiate with the
auction house after it failed to bring the opening bid.  It has arrived
today and it is now on the driveway in the crate as I slowly and carefully
unpack it. 

So far, I have only taken out the regulator tower (an enhancement designed
by Siemens for use with an electric motor (governor essentially)). Take a
look at some photos. The first few are pictures from the auction site. Then
some of the crate.  The best part is a  video showing how easily the
regulator tower spins as if it were manufactured yesterday! Really
incredible. I'll post more as I uncrate more!
