Abstract
A rotatable barrel assembly, generally referred to as a metal finishing barrel, includes a latch assembly that selectively secures or latches the door during a portion of the barrel rotation. In a preferred arrangement, a latch member of the assembly is weighted so that a latch finger prevents movement of the door from its open position. As rotation of the barrel continues, the weighted latch member then pivots to a second position where the door is free to open and allow unloading of the contents of the barrel.
