ABSTRACT:
An improved crank adapter mounts on the end of a milling machine worktable and enables the operator to adjust the worktable lateral position with a forward facing crank. This relieves the need for the operator to reach past the worktable end and manipulate a sidewards facing crank. The crank adapter mechanism includes a bevel gear mounted on the end of the worktable lead screw which engages a second bevel gear driven by a forward facing crank. The crank adapter mechanism can be mounted on either or both ends of the worktable after removal of the existing end plate or end plates.
