Apparatus for sampling fibers which is simplified over previous apparatus for like purpose. A part of the fiber collecting chamber is movable to form a valve for admitting or excluding cotton; a part of the collecting chamber acts as dogs to hold the cotton in the sample chamber with each stroke of a platen; each stroke of the platen cleans the side walls of the collecting chamber; and means is provided for packaging the sample. The apparatus lends itself to automation so that it will collect a sample and eject and package the same after a predetermined number of strokes of the platen. |
