A Multiple Pole Lifter has two or more Vertical Supports. The model to the left has the Tilt Assembly at the top and is moved back and forth by the Drive Wheel in the middle. On the other side of the Tilt Assembly Support is where the power is applied. Tension Tilt Cables are shown off to the side. They could be used for manual operation instead of the Drive Wheel. The small wheels at each end of the Tilt Assembly are ratchet gears with the cable held in place by friction and the Tension Tilt Cables. They allow only one direction of travel while the Carriage is being tilted. When the Carriage is in its upper position they will have their direction of rotation reversed so as to allow the Carriage to be free to drop. This is also true of the ratchet gears under the Carriage as they rotate one way only when the Carriage is going up and reverse when the Carriage is lowered.

The Tilt Assembly uses a Whitworth Quick Return Mechanism. It is by no means the only way of converting a rotational force to horizontal motion. A search on the internet will result in many designs of reciprocating machines. Any such assembly might be used as they are applicable to the Lifter design chosen.
