  • Orbital barrel finishing machine and automated system therefor
    Patent number: 4718199
    Abstract: An orbital barrel finishing machine employs rotatable drums which are removable from the machine. A coupling member mounting a plurality of angularly spaced axially extending pins engages slots of a second coupling member to provide a rotational drive engagement for the removable drums. The drums are uncoupled from the drive engagement by axially displacing the drums. A releasable latch assembly is employed to secure the drums in the coupled drive position. The orbital barrel finishing machine is employed as a component of an integrated automatic finishing system wherein the rotatable drums may be automatically removed from the machine, unloaded, loaded and returned to the machine.
