[GreenKeys] Teletype Model 242 (?)

[Don Robert House]

Hi Ken,

Yes,  The model 242 was submitted by TTY Corp for use in U.S. Navy P2V  
Neptune aircraft.  Approximately 50 plus machines were built.
The two I had are still at the museum in storage among hundreds of  
other interesting equipment items at the San Diego State University  
Library.
I bought the two machines from an eBay seller back in 1999-2000  
timeframe from a surplus guy in Jacksonville, Florida.
As I recall I paid $25. plus shipping for the two.  The manual was  
interesting as it was an original typewritten copy with  8 x 10 glossy  
photos.
As George mentioned the machine resembled the later production M32 and  
M33 as far as the platen, typewheel and ribbon mechanism.
Also interesting was the reuse of certain model 28 components such as  
the carriage return dashpot.
When I served in VP-16 at NAS JAX we had the MITE on our P2V5s and  
also on our P3A Orions.  George and I believe the 242 failed to
meet the Navy's requirements due to the primitive gearing which was an  
arrangement with three directly interfaced gears.
Any friction or binding in the machines mechanism would cause the  
gears to strip teeth.
After the trial TTY Corp presumably saw the design error and came up  
with the belt drive and clutching mechanism we are familiar with since  
1963.

I will send you a couple of poor images of the 242 that I still have  
on my computer somewhere here, if I can find them.

Best regards,

Hi all GK’ers...

A few days ago, George Hutchinson in one of his great posts, described  
a Teletype Corp’n.
Model 242, which was to compete with the Mite teleprinter...I have  
been familiar over the
years with just abt everything TTY Corp’n built, but this one escapes  
me!

I wud like to hear more abt this particular machine...Apparently Don,  
had one or more of these machines.

I did hear some yrs ago, TTY designed a printer (Similar to the M32?),  
for the US Miltitary...Was this the same
one?

Thank you for any info you guys can share with me re: this mysterious  
printer.

Cheers!
