The spout folds to a stored position and the cover member moves to closed position when the cylinder is reversed in direction of operation.，下面是Hydraulic operated dumping spout and cover for side dump box专利的具体信息内容。
1. A dumping box tiltable about an axis extending along one side thereof and above the lower portions of the box to permit dumping material from the box along one upper edge, including a dumping spout member mounted adjacent said one upper edge having a wall positionable in a first spout position to extend the effective dumping edge of the box outwardly from said one upper edge, a cover member for said box, means to mount said cover member on said box for movement relative to said box from an open to a closed position, linkage means connected to said cover member and to said dumping spout member, power actuating means, and means to connect said power actuating means to control movement of said dumping spout member and said cover member between their respective positions through said linkage means.
2. The combination as specified in claim 1 wherein said dumping spout member comprises a first wall member, said first wall member being movable from a position overlying said box when the dumping spout member is in a second stored position, to a position to receive material discharged from said box when the box is tilted, and to guide material from the box laterally outwardly from the one upper edge of said box in the first spout position.
3. The combination as specified in claim 1 wherein said means to mount said cover member comprises a plurality of pivoted links, said links being pivotally mounted to said cover member and to said box to provide guidance of said cover member as said cover member is moved to its open position.
4. The combination as specified in claim 3 wherein said linkage means includes an actuator link connected between said dumping spout member and said pivoted links.
5. A dumping box having sides and an open top and including a frame, means to pivotally mount said box to said frame for pivotal movement about a first axis positioned above the bottom of the box and along a dumping side of the box, power means to tilt said box about said dumping axis, and a dumping spout and cover combination for said box comprising a cover member of size to fit over at least a portion of the open top of said box, and a dumping spout member, means to mount said dumping spout member to said box adjacent the dumping side thereof to be movable from a stored position to a dumping position, means to mount said cover member to said box for guidably supporting said cover member for movement from a closed position wherein said cover member is over the top of said box to an open position where said cover member is clear of a substantial portion of the top of said box, linkage means connecting said dumping spout member and said cover member whereby pivotal movement of said dumping spout member and movement of said cover member occur simultaneously, and power means connected to actuate said dumping spout member and said cover member to positions wherein said cover member is in Its open position, and said dumping spout member is in its dumping position to form an extension from the dumping side of said box.
6. The combination of claim 5 wherein said means to mount said cover member include a plurality of links for supporting and guiding movement of said cover member to its open position, means to pivotally mount first ends of said links to said cover member and means to mount second ends of said links to said box.
7. In a box having sides and an open top and including a frame, a cover member of size to fit over at least a portion of the open top of said box, means to mount said cover member to said box comprising first pivoted link means attached to said cover member adjacent a first edge of the cover member and to said box, and second pivoted link means attached to said cover member adjacent a second opposite edge of said cover member and to said box, said first and second link means being of different lengths and guiding said cover member for movement from a closed position wherein it is over the top of said box to an open position where it is clear of a substantial portion of the top of said box and said second edge and a major portion of the cover member are between a plane passing along the top of the box and the normal bottom of the box and are laterally offset from the box a distance substantially less than the distance between the first and second edges, power means, and means connected between said power means and said cover member whereby actuation of said power means controls movement of said cover member between its closed and open postions.
