Abstract

See full text

An apparatus for unloading a stuffing box is formed from a resiliently deformable material. It features a base and a plurality of elongate finger elements. The finger elements are supported about the periphery of the base, and define outer boundaries of a hollow interior region. Each finger element supports an externally projecting lip. In the relaxed position of the apparatus, the lips project outside the cross-sectional profile of the base. In a compressed configuration, the lips are fully contained within the base's cross-sectional profile. When the apparatus is inserted into a stuffing box loaded with coaxially aligned annular packing elements, it assumes a compressed configuration until the lips clear the lowermost packing element to be removed. The apparatus then assumes a relaxed position with the lips engaging the underside of the lowermost packing element. The apparatus and the engaged packing elements are then withdrawn from the stuffing box.
