Abstract
This relates to an abrasive cleaning machine wherein there is mounted within a suitable frame or housing a work supporting conveyor which is mounted for both reciprocatory and rotational movement. When the conveyor is in the form of a rocker barrel, the rocker barrel is only oscillated. On the other hand, when the conveyor is in the form of a cage-like conveyor, the conveyor is continuously rotated. The principal feature is the mounting of the conveyor for such rotary and reciprocating movement. This includs a support structure in the form of a support sleeve mounted for rotation and a support shaft mounted within the support sleeve for relative reciprocatory movement. The support shaft carries a pair of longitudinal ribs which are engaged by rollers carried by the support sleeve to transmit rotational movement from the support sleeve to the support shaft. Thus the supporting of the conveyor is simplified. When the conveyor is of the cage-like type, it may be provided with a suitable gate and pusher arrangement for discharging workpieces at the terminal end thereof.
