ABSTRACT:
A unique shroud assembly covers the outlet nozzle of a high pressure hand held discharge device. The shroud assembly has a stationary tubular sleeve spaced generally circumferentially about the outlet nozzle and a pivotable tubular end cuff that is spaced from and encircles the outlet end of the stationary tubular sleeve. The pivotable tubular end cuff is capable of pivoting along the longitudinal axis of the outlet nozzle of the spray device. This enables the operator to hold the outlet nozzle at a plurality of angles with respect to the surface being treated while maintaining the necessary flush contact of the outlet opening of the discharge device with the treated surface. Additionally, the stationary tubular sleeve is provided with a laterally positioned outlet for attachment to a vacuum source to suction expelled fluid carrying loosened debris from the treated surface. The pivotable tubular end cuff may have ball bearings provided on an end surface that is in sliding contact with the treated surface in order to reduce surface friction.
