  • Patent number: 6996935
    Abstract: A gate regulator increases the productivity of unloading agricultural material from forage boxes. The gate regulator enables a box gate to swing open without restriction, but the gate is controlled for slow swinging closed. At a gate release position, the gate regulator releases control of the gate such that it swings freely by gravity from the release position to the closed position. The freely swinging gate has enough momentum to automatically relatch the gate closed. In one embodiment, the gate regulator includes a fluid cylinder with a cylinder pin that is received in an L-shaped slot on the gate. During controlled swinging closed, the cylinder pin is within one of the slots of the L-shaped slot. At the gate release position, the junction of the two slots is at the cylinder pin, which then has room to move freely in the other slot and thereby release the slot from the cylinder pin.

  • Patent number: 4854076
    Abstract: An air cylinder operates a loose link cam fixed to a rod which pivots the hatch cover which is normally latched closed. As the cylinder is operated, the first portion of the movement unlatches the cover and the remainder of the movement swings the cover up to an over centre position whereupon it falls by gravity to the fully opened position without any further movement of the cylinder. The loose link cam permits the cover to move through approximately during the opening motion. when closing the cover, the same action takes place with the latch moving to the closed position by means of a spring and being displaced by the cover falling to the closed position by gravity once it has been moved by the loose link cam to the over centre position. The upper surface of the latch hook is curved so that the edge of the cover cross bar strikes the latch and displaces same as the cover closes and which is then returned to the latching position by the spring.

  • Patent number: 4782628
    Abstract: A housing and telescoping arm are supported by a shaft pivot pivotally mounted in the ground. The telescoping arm includes a rotating rod actuator journalled for rotation in a bearing mounted atop the shaft. The rod includes a threaded portion extending longitudinally from the shaft to the gate. A traveling tubular member is mounted concentrically with the rod and includes a block having a threaded bore for receiving the threads of the rod. The arm is connected to the gate through a pinned connection between one end of the traveling member and a lower rail of the gate. Relative rotation between the rod an the traveling member is prevented by the pinned connection. As a result, the traveling member extends outwardly and retracts inwardly in response to the counter-clockwise and clockwise rotation respectively of the rod. A motor and transmission for driving the rod in rotation are mounted in the housing along with a motor control circuit.

  • Patent number: 4598496
    Abstract: Disclosed here is a lid moving mechanism for use with a storage bin. A hinge arm is pivoted at one end to a fixed point on the bin top, and a free end is attached, by a boom, to the lid. A jack device rotates the hinge arm and lid between opened and closed positions. The jack takes the form of a tube, within which is fixed an open-center helical spindle. A turning tube is inserted into this spindle, and a pin engages the spindle windings. When the turning tube is rotated, it is drawn into or forced out of the helical spindle and jack tube, and the hinge arm is correspondingly moved. An extension is attached to the turning tube so that the jack can be operated, and the lid moved, from a remote location.
