A finishing device in the form of an annular bowl adapted to house media and parts to be finished and means for imparting vibratory energy to the bowl to cause the media and parts to progress in agitated movement about the bowl, means for unloading the parts without removal of media from the bowl in which use is made of barriers introduced to extend angularly into the bowl with the barriers spaced one from the other across the bowl by an amount greater than the maximum cross-section of the media but less than the cross-section of the parts whereby the parts are retained by the barriers and caused to travel up the inclined barriers while the media continues through the barriers for continued excursion about the bowl.

In a finishing device having an annular bowl adapted to contain a charge of treating media and work pieces or parts of larger cross-sectional dimension than the media, and means for vibrating said bowl to cause the media and parts to travel circumferentially about the bowl, a means for unloading the parts without removal of the media from the bowl comprising a plurality of elongate rigid bars spaced one from the other across the bowl by an amount greater than the cross-sectional dimension of the media but less than the cross-sectional dimension of the parts, means mounting the bars for rocking movement between a raised position above the level of the parts and media in the bowl and a lowered position in which the bars extend angularly downwardly into the bowl in a direction opposite the direction of movement of the parts and media about the bowl and in which the bars are dimensioned to have a length to extend from the bottom of the bowl to a level above the parts and media in the bowl when in lowered position, whereby the media passes between the bars for continued excursion about the bowl while the parts are diverted by the bars for travel on the surfaces of the inclined bars up the incline, and a means at the upper level of the bars for receiving parts displaced on the bars to the upper level.
