Abstract
A hatch anti-accumulator constructed from a suitable plastic material formed into a rectangular sheet. Slots designed to accommodate fasteners are provided near each end of the material. The rectangular sheet is then bent or rolled to form a short cylinder or ring conforming to the shape of a loading hatch and/or nozzle, and forming a bib or sleeve around the exterior of the hatch and/or nozzle. The bib is then secured in position by installing fasteners through the slots provided. The anti-accumulator fits around the loading nozzle (or hatch coaming) on the top of cement hopper cars to allow accumulated cured particulate matter to be easily released from the nozzle.
