  • Patent number: 11821188
    Abstract: A drain cleaning machine for moving a snake in a drain. The drain cleaning machine includes a rotating shell, a motor, radial drive mechanism, a translate mechanism, and a selection mechanism. The selection mechanism includes an actuating lever moveable between an activated position and a deactivated position, a selection plate moveable between a radial drive position and a translate position, and a push plate. The push plate is moveable in a first direction relative to the selection plate in response to the actuating lever moving to the activated position, and is moveable in a second direction relative to the selection plate in response to the actuating lever moving to the deactivated position. When the selection plate is in the radial drive position and the actuating lever is moved to the activated position, the push plate moves toward the selection plate to switch the radial drive mechanism to an engaged state.
