Japanese Patent JPS5085526
Kind Code:
A
Abstract:
A rotatable barrel for the surface treatment of particulate matter enclosed therein including a generally round perforated barrel with end elements. An opening is provided in the side for the insertion and discharge of particulate matter and a door for opening and closing said opening is mounted on lever arms to swing in an arc between open and closed positions. The lever arms are mounted on hubs extending from the ends of the barrel along its axis of rotation and are mechanically, rigidly attached to gears spaced from the ends of the barrel. A limitation is placed on the arc through which the door may swing relative to the barrel; stop means are provided both adjacent one edge of the opening and remote from the other edge of the opening whereby the door may swing into closed position in abutment with the one stop means adjacent the opening and may swing completely out of the opening into engagement with the other stop means. The door serves as the driving mechanism for turning the barrel in response to the direction of gear rotation.
