ABSTRACT:
Apparatus for removing the outer casing from the rim of a wheel so that each part of the wheel may be recovered separately for purposes of salvage or repair. The wheel is laid on its side upon a worktable having a circular opening formed therein with the rim of the wheel being positioned over the opening. A cylindrical clamping tool is brought down over the rim to engage the casing and securely clamp is against the top surface of the table. A knockout bar is passed down through the cylindrical clamping tool to contact the rim close to the bead-forming joint between the casing and the rim. Extension of the arm causes the bead to be broken and the rim to be forced away from the casing whereupon it falls through the opening in the worktable.
