  • Patent number: 4861226
    Abstract: An apparatus for stacking small articles in a side-by-side stack and feeding the stacks to a discharge conveyor. A plurality of articles, such as small video cassette containers, are conveyed in an upright end-to-end relation on a first conveyor. As each article approaches the downstream end of the conveyor, it is pushed laterally across a platform against a movable backstop to form a side-by-side stack of articles. The stack is then transferred into a movable carriage and the carriage is moved to a position over a discharge conveyor. The end of the carriage facing downstream in the direction of movement of the discharge conveyor is provided with a movable gate and after the carriage is in position over the discharge conveyor the gate is opened to release the stack for movement on the discharge conveyor.
