Patent for an acetylene gas generator. Illustration included.
Acetylene-Gas Generator.
Patent for an improved acetylene-gas generator "which is kept in a relatively-cool condition by a surrounding bath of water and which generator is removable at will from the floatable bell of the tank. A further object is to prevent the waste carbid from dropping into the water of the expansible tank and to provide for the free discharge of gas from the generator [...] while [...] permitting the expeditious removal of said generator for the purpose of cleaning and recharging" (lines 13-24).
Acetylene-Gas Generator.
Patent for an acetylene gas generator, which is chiefly operated by the fall of a gas-bell.
