Re: [time-nuts] IBM TYpe 37 Master was Re: IBM's Clock Corner
Hi, Russell, I just recently sold my IBM Type 37 to a collector in the Los Angeles area. I have the factory documentation for it. If you send me your snail mail address, I will run off a copy for you. This is indeed a fabulous clock. Mine was built in 1957. It used the 3-minute 600Hz. tone that WWV used to send to synchronize itself every hour. The 3-minute tone was validated by using a rotating cam switch driven by a separate synchronous motor. WWV changed its broadcast format a few years later to send one-minute tones instead of 3 minute. There is one of these on display in the lobby of the NIST labs in Boulder, Colorado. email me at couchclocks at yahoo dot com (make the obvious changes in the email address).

[time-nuts] IBM TYpe 37 Master was Re: IBM's Clock Corner
I've actually had reason to reference this IBM resource myself recently. Unfortunately they don't have much in the way of detail on the Type 37 Master. I just acquired on of these Type 37 masters and I am looking for technical information on it. I've found ONE reference on the NAWCC forums to someone who scanned the service information for it and put it on the web, but that link is no longer working. Wnd while I did send an email to the person who had it up, I have yet to hear a reply. I called up Simplex (who bought the IBM clock business) and the person I spoke to was very friendly and spent some time looking for older service information, but didn't have anything readily available for a 50 something year old clock... So, I turn to my fellow time nuts and ask if anyone here might be able to help. Incidentally, for those who have never heard of it, the Type 37 is a rather interesting clock for time nuts. It's an electro-mechanical master clock, with a nice Invar pendulum, several Telechron style 60 hz synchronous motors, AND a late 50's vintage vacuum tube radio to receive the late 50's vintage WWV signal. A commercially made radio controlled pendulum master clock, very nifty :) When this was built, WWV was broadcasting out of someplace much further east than Colorado (Maryland if memory serves) and was broadcasting time signals using what I have seen described as railroad morse code rather than today's more familiar mix of digital and analog signals. -- Russell ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
