John Tann Isolator Boltwork

[Huw Eastwood]

I have seen the Ratner one, but not the Tann one, do you have any info as to how it worked or what it was fitted to?

Gary what's the Ratner version like?

Don't know of any Tann version of an isolator boltwork.

This is the Ratner Lee-Matic :-

and Patent illustration.

Thanks safeman, Gary mentioned the Ratner Lee-Matic recently in a different post and I wondered what it referred to. Have seen a real mixture of Ratner's but have never seen one of those.
