Abstract
A pipe cleaning brush assembly for attachment to the rotatable face plate of a pipe facing machine for rotation therewith to clean the outer surface of a large diameter pipe section proximate the end thereof simultaneously with the machining of the pipe end face. The assembly includes a clamp having an inverted U-shaped member for placement over the edge of the face plate with a clamp jaw lock acting as a vise to grip the face plate and a clamp wedge lock engaging the face plate to resist centrifugal forces developed during rotation. A brush arm is pivotally mounted to the clamp, with a brush attached at one end and a cam at the other. The cam upon rotation causes the brush arm to pivot between a retracted position wherein the brush is held above the pipe surface to be cleaned and a position wherein the brush rests on the pipe surface.
