Abstract
The invention contemplates a gas-torch construction wherein independent flows of combustible gases are maintained up to the point of mixing within the nozzle of the torch, virtually at the location of discharge from the nozzle. The nozzle is removably connected to an elongate intermediate or adapter member, and the latter is removably connected to the torch body. The separate flows of the gases are maintained independent of each other, from the torch body, through the adapter member, and into the upstream end of the mixing nozzle. Individual radially spaced manifolds at the adapter-to-nozzle connection assure independence of the gas flows and a non-critical angular relation when the nozzle is replaced. The invention is described in application to a powder-spraying gas torch, as for torch deposition of metal coatings.
