Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 418 words
A harpoon-type conveYor, comprising: means defining an elongated conveyor trough; elongated post means fixedly secured to and extending upwardly from the bottom of said conveyor trough means and extending longitudinally of said conveyor trough means, said post means comprising substantially vertically extending plate means and cylindrical rail means fixedly connected to said plate means adjacent the upper end thereof; at least one hollow cylindrical conveyor rod having an elongated slot-like opening extending longitudinally along the lower portion thereof, said opening having a pair of laterally spaced edges, the spacing between said edges being sufficient to receive said plate means therebetween; said hollow cylindrical conveyor rod being disposed in surrounding relationship to said cylindrical rail means for permitting said conveyor rod to move back and forth relative to said elongated post means, said conveyor rod having an internal diameter substantially larger than the external diameter of said cylindrical rail means whereby the upper inside surface of said hollow conveyor rod is slidably supported on the upper surface of said rail means with the remaining inside surface of the hollow conveyor being substantially spaced from and free of contact with the exterior surface of said rail means, whereby said conveyor rod tends to pivot about the area of engagement of said conveyor rod with the upper surface of said cylindrical rail means, the magnitude of pivotal movement being sufficient to tend to cause an engagement of said edges of said opening with the laterally facing side surfaces of said plate means; conveying means mounted on said hollow conveyor rod for movement therewith; and slide bar means mounted between said edges of said opening in said conveyor rod and said laterally facing side surfaces of said plate means for minimizing wear of said laterally facing side surfaces of said elongated post means due to engagement of said edges of said opening caused by a pivotal movement of said conveyor rod relative to said post means; said slide bar means including a pair of substantially parallel wear plates disposed between the edges of said opening and fixedly secured to the opposite side surfaces of said plate means, the combined thickness of said pair of wear plates and said plate means being less than the width of said slot-like opening as defined between said spaced edges, whereby said edges are normally spaced from the external side faces of said wear plates, said edges being engageable with said side faces in response to pivotal movement of said conveyor rod relative to said rail means.
Claim 2
Dependent Claim 418 words
A harpoon-type conveYor, comprising: means defining an elongated conveyor trough; elongated post means fixedly secured to and extending upwardly from the bottom of said conveyor trough means and extending longitudinally of said conveyor trough means, said post means comprising substantially vertically extending plate means and cylindrical rail means fixedly connected to said plate means adjacent the upper end thereof; at least one hollow cylindrical conveyor rod having an elongated slot-like opening extending longitudinally along the lower portion thereof, said opening having a pair of laterally spaced edges, the spacing between said edges being sufficient to receive said plate means therebetween; said hollow cylindrical conveyor rod being disposed in surrounding relationship to said cylindrical rail means for permitting said conveyor rod to move back and forth relative to said elongated post means, said conveyor rod having an internal diameter substantially larger than the external diameter of said cylindrical rail means whereby the upper inside surface of said hollow conveyor rod is slidably supported on the upper surface of said rail means with the remaining inside surface of the hollow conveyor being substantially spaced from and free of contact with the exterior surface of said rail means, whereby said conveyor rod tends to pivot about the area of engagement of said conveyor rod with the upper surface of said cylindrical rail means, the magnitude of pivotal movement being sufficient to tend to cause an engagement of said edges of said opening with the laterally facing side surfaces of said plate means; conveying means mounted on said hollow conveyor rod for movement therewith; and slide bar means mounted between said edges of said opening in said conveyor rod and said laterally facing side surfaces of said plate means for minimizing wear of said laterally facing side surfaces of said elongated post means due to engagement of said edges of said opening caused by a pivotal movement of said conveyor rod relative to said post means; said slide bar means including a pair of substantially parallel wear plates disposed between the edges of said opening and fixedly secured to the opposite side surfaces of said plate means, the combined thickness of said pair of wear plates and said plate means being less than the width of said slot-like opening as defined between said spaced edges, whereby said edges are normally spaced from the external side faces of said wear plates, said edges being engageable with said side faces in response to pivotal movement of said conveyor rod relative to said rail means.
Claim 3
