  • Patent number: 4088025
    Abstract: A device for collecting and removing samples by vacuum suction created in a tube with an opening at the bottom. The opening communicates with a connecting chamber that separates the vacuum tube fron two tubes, one inside the other, used to gather the required sample. An orifice permitting a jet of air to cross the connecting chamber and enter the vacuum tube aids in removing the sample from the two tubes. Angled partitions inside the inner tube aid in dumping the sample through aligned openings in the two tubes into the connecting chamber. The tubes are kept at a desired angle when inserted by a spring assembly. The spring assembly also allows break-away movement should the device hit an obstacle.
