[TheForge] Gas miser ?

[Dan Armstrong]

I saw Dave Thompson in Oregon using a device where he could hang up his oxy-acetylene torch and it would shut off the gas thus allowing both hands for riveting and such. I think there may even have been a quick way to re-light. I recall someone refer to it as a gas miser but damned if I can find any reference to such a thing online.

Anybody know what I'm talking about and where to find same ??
