Abstract: Wood chips or other fluent materials are stored in an annularly shaped pile by means of a boom mounted, pneumatically fed pipe. The boom is supported by a stationary tower, and the boom and pipe are provided with coincident pivotal and rotational joints which permit the boom and pipe assembly to be driven in vertical and horizontal planes separately or simultaneously by drive mechanism located on the tower to control the annular ad transverse dimensions of the pile.
