Abstract: Vibratory finishing equipment including a cylindrical drum having its axis set horizontally. The drum is resiliently mounted on a base. The base is equipped so that the drum can be tilted at a desired angle. The vibrators are mounted in an upper quadrant of the drum. The position of the vibrators in the upper quadrant of the cylindrical drum provides a unique combination of rotary, lateral and longitudinal motion which assures that all of the pieceparts are properly finished by the media within the drum.

Abstract: A vibratory finishing system including a tub-like container mounted on resilient means. The top to bottom center line of the container is at an angle to the vertical. The top of the container slants downward from the rear to the front of the container. The interior of the container is substantially linear at the front thereof and arcuate at the rear thereof cooperating to amplify media and piecepart activity. The side walls flare outward to actuate transverse movement of the media and pieceparts. Tandem vibratory means are coupled at the rear of the container above the center line thereof. The plane of the tandem vibratory means can be varied from a position parallel to the top to bottom center line of the container to a position normal to the horizontal. The location of the tandem vibrators enables finishing heavy pieceparts without crushing the media and minimizing contact between the heavy pieceparts themselves and between the heavy pieceparts and the walls of the container.
