Abstract A weapon for producing a nonlethal, voluminous fog of tear gas or riot control agents or material for controlling one or more persons is provided with a two-cycle internal combustion engine that drives an air blower. A manifold is connected to the engine exhaust to cause the exhaust gases to turn at least 90*, and pass through a pipe to be discharged in the outlet opening of the blower. The liquid to be produced as a fog is drawn or injected into the manifold, and is vaporized by the hot exhaust gases. This vapor is discharged or drawn from the pipe by the air blown by the blower and further atomized to efficiently produce a dense, voluminous fog containing air, the vaporized and atomized liquid material, and the engine exhaust gases.
The improved weapon of claim 1 wherein said blower is a squirrel cage-type of blower.
