  Device for preventing inhalation of dust or the like.



   The device consists of a metal drum n which is provided with several openings in the upper part. A fan wheel r is inserted into this drum, which rotates rapidly when breathing and prevents dust from entering the drum.



   An ebonite cap v, which is also inserted into the drum n, has two types of inclined openings; only through the outer d does the air flow when exhaling sud drives the wheel) '; the inner, smaller openings d have the purpose of reducing the counterforce exerted on the wheel? 'during inhalation, and are provided on the inside with a flap c which covers these smaller openings during exhalation.
