Abstract: A self-contained activated slide apparatus of the single or double bar configuration. The apparatus includes a housing which is slidable relative to a bar, or vice versa. The housing may be fixed to an external element, or the bar may be so fixed. The length of the slide stroke may be controlled by the use of stops on single bar slides, and by the use of adjustable end bar assemblies and stops on the two-bar units. The slide apparatus may be activated and controlled from within by the use of a fluid power medium. Slide action may be fully controlled by controlling the pneumatic or hydraulic power source and flow.
