Abstract: A device for removing foreign matter that collects on a cleaning bar in an apparatus for cleaning fibers of material. The device includes a scraper slidably mounted on a cleaning bar, such as a grid bar in a lint cleaner for scraping foreign matter and lint off the grid bar when the scraper slides along the length of the grid bar. The scraper includes a scraper bar that is in sliding contact with a top surface of the grid bar. The edges of the scraper may be sharp to improve the scraping efficiency. A scraper back plate extends from the scraper bar. The scraper and back plate are mounted on the grid bar using a guide block so that the scraper is slidable along a length of the grid bar. A guide rail may be mounted first on the grid bar to facilitate mounting of the scraper on the grid bar.

Abstract: Apparatus for removing foreign matter from cotton comprising a plurality of extractor cylinders in series, and a plurality of reclaimer cylinders in parallel, one for each of the extractor cylinders, wherein the first reclaimer cylinder directs reclaimed cotton to the second extractor cylinder in the series.

Abstract: An apparatus for sampling dust from lint cotton is disclosed. Air is blown through a known sample of lint cotton positioned in a holding fixture to remove the dust. A suction means is provided to move and direct the dust removed from the lint cotton sample to a filtering means which gathers the dust for subsequent weighing. This accurate dust sample is then used to program experiments for improving the health and safety conditions in the lint cotton process as well as the efficiency of the machinery used in lint cotton processing.
