Abstract
Abstract A power actuated cleaner for cleaning the threads on the ends of tubular members including a housing having a rotatable disc in the housing with power means connected to the disc for rotating the disc. A plurality of cleaning brushes are provided, each of which is connected to one of a plurality of brush adjusting arms. The brush arms are pivotally connected to the disc with a releasable connection between the adjusting arms and the disc whereby the arms may be rotated on the disc for moving the brushes for coacting with different sized pipe. The housing includes an opening at one end with a plurality of guide adjusting arms, each of which supports a guide support for a pipe, pivotally connected to the housing about the opening. A releasable connection between the adjusting arms and the housing allows the guide arms to be rotated on the housing for guiding and aligning different sized pipe into the opening. Coacting indicators are positioned between the brush adjusting arms and the disc and between the guide adjusting arms and the housing indicating the adjusted position of the arms. A conduit extends from the outside to the inside of the housing and is carried by the rotatable disc. An air supply and a solvent supply is connected to the conduit with a valve which may be alternately actuated to spray solvent on the threads or blow cleaning air on the threads.
