Historical information

Smokers are used to calm bees. This is done by putting some kind of fuel into the chamber (pine needles, hessian, anything that smokes a lot when it burns), lighting it, then puffing the bellows to bring forth the smoke. The smoke has a calming influence over the bees, and helps stop them from stinging.
The guard around the outside is to prevent burns via contact with the hot chamber.
