ABSTRACT:
A manually operable device for metering air through a valve system for drawing into, retaining and evacuating material from a chamber having a first air passageway operatively connected to the chamber and exposed to the atmosphere for transporting the material, a second air passageway operatively connected to the chamber, an oscillating air source for moving air within the second air passageway and a valve mechanism operatively connected to the second air passageway which when in a first position upon actuation of the oscillating air source moves air creating a partial vacuum within the chamber causing material to be drawn into the chamber, and when in a second position upon actuation of the oscillating air source causes air to be introduced under positive pressure into the chamber evacuating the material from the chamber into the first conveying mechanism and a third air passageway coupled to the valve assembly which allows the second air passageway to vent to the environment.
