Patent abstract
An improved top pot assembly utilizes an attachment body for attaching the rubber to a bearing assembly for rotation with the inner barrel. The attachment body simplifies the replacement of the rubber on the drilling assembly. The attachment body provides a guide that slopes downward into the central aperture and the bore to guide the mandrel and drilling string towards the bore. The attachment body also provides a stripper receiver for attachment of the rubber to the attachment body. The attachment body attaches to the housing which attaches to the bearing assembly for rotation of the rubber and the inner barrel.
