Abstract
The barrels orbit to create a centrifugal force on the barrel contents while the barrels are concurrently rotating about internal axes counter to the orbital movement, utilizing endless members to impart both the orbital and counter rotating movement to a plurality of the barrels.
Claims6
In a surface finishing machine of the type having a stationary frame and a rotary turret, a finishing barrel supported on the turret for orbital movement in one angular direction about a first axis to impart a first centrifugal force on contents of the barrel, the improvement comprising sling mounting means carried by the turret and engageable with the barrel for supporting the same for radial movement relative to the first axis, said sling mounting means including an endless continuous drive member having a loop in which the barrel is slung and limiting radial displacement of the barrel from a stationary starting position upon orbital movement thereof while causing the barrel to rotate continuously in the opposite angular direction sufficiently to impart a second force on contents thereof to modify the effect of the first centrifugal force and wherein said machine has a plurality of said barrels each of which is slung in an individual loop of said endless member.
