Clock for Torpedominen

[Antoon]

Hello,

Who has information about this clockwork as used bij German Frogman in there "Torpedominen" during the attack on the Waal-river bridges in the Netherlands, after Operation Market Garden?

It does look a lot like a regular UES (Uhrwerkseinschalter), are there any markings on the baseplate ?

Best regards,

Zünder

Oeps, Not available. Will ask the museum if they have a picture of the bottom.

Is there documentation available?

Yes,

see: https://www.scribd.com/document/734410407/Op-1673a-German-Underwater-Ordnance
Starts at page 235

There's also a Kriegsmarine manual: M.Dv. Nr. 658, but i am still looking for that one.
A good book to have is Wolfgang Thamm's "Einsatzfähige deutsche Fernzündgeräte", which describes german WW2 fuzesystems for naval and aircraft mines as well as clocks like the UES.
It was/is published by comprints.de, ISBN 3-86611-108-8.

Groeten,

Thanks for sharing, the To-Minen is a tough subject.
According to what I've learnt, a few models were designed in the period ranging from June to October 44; the late Nipolit model used to be fitted with Italian 10hrs clockworks (the same fitted on the minor charges) but I've found also early references about 6hrs devices, which might well be yours. May I kindly ask who links this devices to the To-Minen?

Someone who is writing a book about the attacks by Sondereinsatzgruppen on the Waal-river bridges in September 1944.

As far as I know the clock is in the Liberation museum in Groesbeek (NL) and is donated by someone who defused one of these Torpedominen. Will ask for the exact story.

the UES II as mounted in the TMB II and TMC I:


But they were used also in other mines like the SMA:

Are these sterilization devices right? I assume with days long delays, while Antoon's one has a hourly graduation in quarters with a safety of 30 minutes.
This is the first time I've found an evidence of the 6hrs clockwork, encased into the original device. I'm wondering if this was fitted before the introduction of the Italian clockwork or if both were fitted together, one being the sterilizer. Looking forward for Antoon's story.

Schärfereinrichtung means, that it was used to arm the mine after a set delay time.

Here is another clock, this time from a drifting mine (sic), and recovered from the Seine, Orival Bridge, but similar time, 17/9/44.
