Patent 24761/93. Price 3Os.,
This is the only perfect Mixed Jet which can be worked with coal-gas taken direct from the town supply, and oxygen at
high pressure from acylinder. It combines the full efficiency of a mixed jet with the safety, economy and convenience of
a blow-through. Blow-through jets are quite superseded by it. An ordinary mixed jet which will produce aay given
candle-power when supplied with both gases under pressure will, when fitted with our Injector, give the same Power
when taking its coal-gas supply from house the service-pipa. When required the jet can be worked with both gases taken from cylinders just as an ordinary mixed jet.
