Abstract: Positioning apparatus is disclosed which positions an object with respect to two predetermined lateral positions. In addition, the object is indexable by the apparatus in a step-by-step manner in an incidental direction with respect to each of the two lateral positions. It includes an endless sprocket chain entrained about two sprocket wheels. The chain carries a first member which is pivotably connected to the chain. A second member is affixed to the first member and is adapted to support the object. The second member is slidably mounted to a movable third member which in turn is guided by guiding means such as rails that guides the third member means in a predetermined aligned relationship with the reaches of the chain. In addition, chain guide means guide the chain along the first and second reaches. Driver means are coupled to one of the sprocket wheels to drive the endless chain. In response to the movement of the chain, the first member is capable of movement to and along each of the chain's first and second, i.e., two, reaches. The object in turn is thus positionable with respect to the first and second positions when the chain carries the first member along the first and second reaches, respectively. In the preferred mode of operation, the chain is driven in one direction to move the object from the first position to the second position and in the reverse direction when the object is returned from the second position to the first position.
