  • Patent number: 4838411
    Abstract: A lift and carry accumulating conveyor having a frame with a pair of elongated, spaced apart and parallel stationary rails. A pair of elongated, spaced apart and parallel movable rails are mounted to the frame so that the movable rails are movable between a forward and a retracted position as well as between an upper and a lower position and so that the movable rails extend generally parallel to the stationary rails. A shaft is rotatably mounted to the frame and is rotatably driven by a motor. A disk is obliquely attached to the shaft and is mechanically coupled to one end of the lever while the other end of the lever is attached to the movable rails to move the movable rails between the forward and retracted position upon rotation of the shaft. An eccentric cam is also attached to the shaft and, through a plunger attached at one end to the movable rails, vertically moves the movable rails between the upper and lower position upon rotation of the shaft.
