Abstract: A power door system for actuating door panels between closed and opened positions. An operator arm telescopically supports a push rod. A housing is secured to the operator arm. A spring pin extends through apertures in the arm and the push rod. A release cable extends from the housing and is movable to retract the pin, permitting inter-telescoping motion of the push rod relative the operator arm, in turn permitting manual displacement of the doors. A compression spring supported within the housing influences the pin into engagement with the operator arm and push rod. A locking pin and guide is incorporated into a cable mounting guard below the spring pin, the locking pin displacing with the spring pin to a retracted position in response to actuation of the release cable, a successive actuation of the release cable releasing the spring pin and lock pin to reengage the apertures in the arm and the push rod.

Abstract: A gate system (10) includes two spaced sides (12, 14) defining a work area (16) between the sides (12, 14). A first opening (18) is defined between first ends of the sides (12, 14), and a second opening (38) opposite to the first opening (18) is defined between second ends of the sides (12, 14). Two gates (82, 92) for opening/closing the first and second openings (18, 38) are respectively coupled with two shafts (40, 50) rotatably supported by one of the sides (12, 14). The shafts (40, 50) are rotatably interconnected wherein pivoting of one of the gates (82, 92) in a direction causes pivoting of the other gate (82, 92) in an opposite direction. Each gate (82, 92) includes a groove (85, 95) that receives a vertical beam (60, 62) of the other side (14) when the gate (82, 92) is in a closed position. Biasing elements in the form of gas cylinders (110, 120) between the side (12) and the gates (82, 92) prevent the gates (82, 92) from slamming into their closed positions.

Abstract: A mechanism for closing in sequence a first door (D1) and then a second door (D2) has pivot pins (40) mounted to the door frame. Each pin engages a cam plate (30), so that the plate can rotate. Linkages, such as doors arms (20) hinged from each door to the corresponding cam plate, cause the doors to close when the cam plates rotate. A pair of crossed shuttle arms (50, 60) are rotatably coupled to the cam plates. On the first cam plate the shuttle arms are fastened at a radial distance (d/2) from the pivot pin, and on the second the shuttle the shuttle arms are fastened at a greater radial distance (D/2). The two different distances cause the cam plates, as linked by the shuttle arms, to rotate at different angular rates. The door linked to the cam plate with the smaller distance closes first. The mechanism is asymmetrical with the distances from the pivots to the door arms, the lengths of the door arms, and the attachment points of the hasps on the two sides being in general unequal.

Abstract: A drop center livestock trailer is provided with a deck which is vertically adjustable within the trailer body to two separate positions for accommodating various forms of livestock and freight. A sectional gate structure which extends for either the full or a part of the inside trailer width is incorporated in the trailer for assuming a first position in which it acts as a gate limiting the movement of livestock in the trailer and a second position wherein it supports a ramp for facilitating the loading and unloading of the livestock. The ram is pivotally attached to one end of the movable deck and is supported by a lower section of the sectional gate structure. The ramp is allowed to drop from its normal horizontal to an inclined position by moving the lower section of the gate structure to an inclined position. Connected to the lower gate section is an upper gate section which is pivotally connected to the sidewalls of the trailer.

Abstract: A door opener mechanism for the side doors in a feed or grain elevator or conveyor in which the doors are hinged to the sides of the conveyor includes a crank arm pivotally connected to the conveyor at a point intermediate the side walls to provide rotation of the crank arm about a vertical axis. The crank arm is connected to the hinged doors by links and the crank arm is connected to a control arm by a link. The control arm is arranged to be connected to ropes for remote control of the door opening device. The control mechanism employed provides a relatively low profile, thus enabling placement of the conveyor and door opening mechanism close to a ceiling, which is desirable in places of limited space such as old barns.
