  • Manifold for maintaining a latch actuator under pressure and accommodating leaks
    Patent number: 6431049
    Abstract: A double acting actuator is used for operating a pair of latches, and is controlled through a manifold that will permit a base end of the actuator to remain under pressure, and accommodate valve and piston leakage by connecting the rod end of the actuator to drain through a small orifice. The manifold additionally has relief valves for providing different pressures for the rod and base ends of the actuator, and a flow divider that provides a low flow to the actuator while the main flow from a pump is used for other hydraulic components.

  • Vehicle stabilizer attachment and method
    Patent number: 4583760
    Abstract: A stabilizer attachment for a work vehicle. The attachment is linear in operation and when it is attached adjacent one end of a vehicle and is then extended it raises the adjacent wheel off the ground. Another stabilizer attachment on the other side of the vehicle when operated raises the corresponding wheel on the other side off the ground. With the two wheels off the ground more down pressure is exerted on a ground engaging implement and the stabilizers act as a brake securing the work vehicle in position during operation of the implement.
