  • Patent number: 5582287
    Abstract: A zero-pressure accumulating conveyor including a bed defined by rotatable rollers mounted in parallel sidewalls and powered by an endless drive chain. Pneumatic actuators lift the drive chain into engagement with the rollers to empower same. Sensor rollers divide the bed into distinct zones. Sensor rollers are retained in operative position relative to the conveyor bed by unique sensor brackets. A primary sensor roller bracket includes a bore with a piston movable there within; the cooperating secondary sensor roller bracket is spring biased in a first direction. Valves, and pneumatic circuitry controlled by such valves, extend along the length of the conveyor. Such valves are operated by the primary sensor roller brackets to regulate the flow of air pressure into the bores of the brackets and into the actuators. The actuators, when the pressure therein is bled-off, allow the chain in a particular zone to drop out of contact with the rotatable rollers.

  • Patent number: 4697977
    Abstract: A stacker-retriever lift carriage is disposed to be raised, lowered and positioned, in selected positions with respect to a pair of spaced support masts, by a flexible wire cable one end of which is connected to a lift carriage drive and the other end of which is connected to the lift carriage through a pair of four bar linkages pivotally connected together in spaced parallel relationship to form a safety brake operating mechanism. The upward pull by the cable upon the brake operating mechanism retracts a pair of opposed brake arms, pivotally carried by the brake operating mechanism, to a brake deactivated position with the back ends of each brake arm abutting each other. Loss of the pull of the cable on the lift carriage, as would occur if the cable severed or if the lift carriage hung up, permits a spring housed between the brake arms to move the brake operating mechanism and the brake arms to a braking position with brake pads carried by the brake arms in friction engagement with the support masts.
