    Abstract: A self-centering boom for self-propelled agricultural sprayers having a double-acting hydraulic cylinder and a magnetically actuated electrical position sensor and control for sensing and moving the boom to a centered position. The electro-hydraulic control circuit senses boom position when the boom is at or near a centered position with respect to the sprayer and automatically centers the boom when the sprayer drive train is out of a neutral condition. The hydraulic system includes a pair of pressure relief valves to allow the boom to deflect due to inertial forces when turning or when contact is made with an obstruction, with the control system returning the boom to a centered position after turning or when the boom is clear of the obstruction. A flow restricting orifice cooperates with the pressure relief valves to automatically adjust the pressure at the inlet of the relief valve to retard rapid boom movement, while not interfering with slow boom movement.

  • Patent number: 4079555
    Abstract: A flagpole assembly for automatically displaying and furling a flag. The assembly is formed of a first hollow vertical slotted pole mounted concentrically inside a second slotted hollow pole with both poles mounted to a base. A cable, mounted on pulleys extends inside the first pole with the flag fixed to the cable, and extending through the slot of the first pole, and when displayed, extending through the slot of the second pole. The second pole is rotatably mounted to the base. A motor unit serves to wind the cable pulleys and rotate the second pole for furling or unfurling the flag, with associated sensors and limit switches serving to furl the flag during periods of darkness and periods of rain.

  • Patent number: 3977531
    Abstract: A stiff-leg crane for use in handling loads in the erection of buildings and the like, including a base rotatable on a bearing, a vertical mast rigidly mounted at a lower end at the center of rotation of the base, a boom pivoted at a foot end along one end of the base, boom support and load handling lines from the top of the mast to the boom, a pair of adjustable lay leg mast braces for boom and mast support from either the crane base or the structure being erected by the crane, and means for securing the lower free ends of the lay legs to either the base or the structure being erected. The lay legs are adjustable both in length and the angle between the lay legs and the mast. Additionally the lay legs are fully rotatable about the mast and may swing between the mast and the boom for relocation from one side of the mast to the other without interference with the boom or the boom support and load handling lines.

  • Patent number: 3968884
    Abstract: A mobile crane has a multisection telescopic boom and an optionally useable lattice jib storable alongside the boom with the base end of the jib adjacent the point end of the boom. Improved jib storage support means are provided to facilitate storing and installing the jib. Thus, one side of the boom base section is provided with a pair of longitudinally spaced apart jib storage support assemblies. Each support assembly is pivotally mounted so that it can be swung between a jib-supporting position and a stored position. Each support assembly includes a laterally extending member which is tiltable between a horizonal and a downward position so that the jib can be easily swung thereonto for storage and then subsequently locked into horizontal position, whereupon locking brackets secure the jib on the support assembly.
