Bartletts Tongs

A couple of years before he died (at the age of 99) Tommy Bartlett
sent in a tip to Model Engineer regarding a pair of tongs he had made
earlier in his life as an aid to silver soldering. The clamping ends
were graphite rods and I seem to remember that the device had an 'over
centre' arrangement so it was self holding. Intended to clamp small
parts together whilst silver soldering, the graphite neither got fixed
with the braze nor conducted too much heat away.
I cannot track down the details - does anyone else remember it or have
the article that they could scan for me?

ps he worked for Morganite Carbon for many years when they were in
Battersea, hence the use of graphite!
