Abstract: A machine for applying sub-atmospheric pressure through a filter to pull material from a hopper laterally into a non-rotatable chamber at a presettable volume and after the chamber is filled blowing the material out of the chamber through the filter out of a discharge nozzle at the bottom of the chamber into a receptacle. In a preferred embodiment, the material is a pulverulent material which is fluent en masse and the material is aspirated into the measuring chamber by applying a sub-atmospheric pressure above a variably positionable head in the chamber which head has a filter in it through which the suction is drawn. After the chamber is filled, a super-atmospheric pressure is applied over the head to shoot the mass of particulate material out of the discharge nozzle, the particulate material having been held back by a discharge valve prior to the application of the super-atmospheric pressure.
