ABSTRACT:
Disclosed is a fluid powered linear slide employing either a rodless or rod-type cylinder. The slide includes a base which has a movable carriage mounted thereon which moves reciprocably in response to pressurized fluid being fed to the cylinder. In the embodiment employing a rod-type cylinder, a pair of tubular rods are mounted on the base in a fixed position and attached to a piston stationarily mounted inside the cylinder which is movably mounted and attached to the carriage. In the other embodiment, the carriage is mounted on a bracket which is attached to the rodless cylinder carried in the housing for the cylinder. The base has linear guideways therein, each guideway carrying one or more stop members which are manually adjustable and electrically or fluidly actuated. The stop members may be moved to any one of an infinite number of stop points along the guideway and are programable to be actuated or deactuated as desired by energizing an electrical coil which magnetizes a block that moves a latch arm into a position to stop the carriage, or filling or removing gas from a bladder which engages and moves the latch arm.
