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.
Claims14
A rotatable barrel assembly used for surface treatment of workpieces comprising:
- a generally cylindrical barrel adapted for rotation about an axis;
- an opening defined through a sidewall of the barrel through which workpieces may be loaded and unloaded;
- a door that moves relative to the barrel for selective covering relation with the opening;
- and
- a weighted latch assembly that engages the door to the sidewall during only a selected portion of the barrel rotation to preclude door separation from the opening.
A barrel assembly used for surface treatment of workpieces, the barrel assembly comprising:
- a barrel having a sidewall that extends between a pair of end walls and includes an opening through a portion thereof for loading and unloading workpieces into the barrel;
- a door mounted on the barrel for movement along a generally arcuate path for selectively covering and uncovering the opening;
- and
- a latch assembly operatively associated with the door for precluding movement of the door from its covering position over the opening during only a portion of the barrel rotation.
