ABSTRACT:
A machine for washing the internal surfaces of hollow bowl-shaped bodies has a housing whose cover is movable between open and closed positions and has devices for releasably holding and centering a body thereon. The housing supports a driven shaft which carries and rotates two parallel motion mechanisms for brushes extending in parallelism with the axis of the shaft and moving outwardly into engagement with the adjacent portions of the internal surface of a body in the housing when the shaft is driven by a motor. The parallel motion mechanisms are deformed by centrifugal force to move the brushes outwardly in automatic response to rotation of the shaft. The shaft is assembled of sections which are slidably telescoped into each other, and the outermost section carries a further brush which engages the innermost portion of the internal surface of a body which is held by the cover while the latter dwells in the closed position. If the bottom wall of the body is relatively thick, it bears against the further brush and shortens the shaft. The latter has an axial passage connected to the outlet of a pump which feeds a stream of liquid against the internal surface of the body in the housing. Such liquid flows onto the bottom wall of the housing and into a trough to be recirculated into the housing by way of the axial passage in the shaft.
