"Pneumatic probe sampler" means a device for taking samples of grain and other particulate material from the bottom of a bin comprises two concentric tubes spaced sufficiently apart to permit passage of the material when entrained in a stream of air. The outer longer tube has a serrated edge to enable it to penetrate dense sections, while the inner, shorter tube is provided with helical vanes. Air, blown down the outer tube is caused to swirl in a vortex by the helical vanes, thereby entraining material lodged near the bottom of the outer tube. The air, together with entrained material, passes up the inner tube and is conducted to a cyclone separator to recover the sample. (U.S. Patent, US3580084A, May 25, 1971, Expired)
