Abstract
Abstract A conveyor assembly comprises an unloader, particularly for the unloading of bulk materials from ships, comprising a traveling member carrying a boom with a hollow jib which pivotally supports the upper end of a generally vertically extending hollow chute or column of a first conveyor structure which includes an endless conveyor member arranged within the hollow chute and the jib and extends from an annular hopper at the lower end of the chute to its inner discharge at a vertical shaft of the traveling unloader. A support is rotatably mounted at the lower end of the hollow chute and carries a second endless member conveyor. The second endless member conveyor is guided at its lower end over a pulley which is located below the lower end of the chute, and on the side opposite to the rotational axis of the support, there is a deflecting pulley on the end of a pivotal boom which may be adjusted in a vertical plane in order to vary the position of the lower end of the second endless member conveyor which may, for example, be a bucket conveyor. The second endless member conveyor is arranged so that it empties the material conveyed thereby into a central hopper below the chute so that the first endless member conveyor picks it up and transports it through the chute and the jib to the receiving shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
264 words
A conveyor assembly, comprising a support structure, a first conveyor mounted on said support structure and being positionable in a substantially vertical position, a supporting frame mounted around said first conveyor adjacent the lower end thereof, said frame and said first conveyor being relatively rotatably movable in respect to each other so that there is a relative rotation about the axis of the first conveyor in respect to said frame, a second conveyor comprising a bucket chain conveyor having an endless chain with a plurality of buckets therealong and being carried on said supporting frame and including a lower reach extending laterally of said first conveyor and below said frame, a guide roller for said second conveyor carried by said supporting frame and being located below and on one side of said first conveyor, and a pivot arm rotatably supporting said deflecting roller and pivoted on said supporting frame to extend outwardly from said frame on the opposite side of said frame from said guide roller, said second conveyor chain being guided over said guide roller and said deflecting roller through a path which may be shifted laterally and vertically by adjustment of the angular position of said pivot arm by pivoting said pivot arm, and means on said supporting frame for pivoting said pivot arm, said second conveyor also including an upper portion located above said supporting frame, and a receiving conveyor located on said supporting frame below the upper portion of said second conveyor in a position to receive material from said buckets and to deliver the material to said first conveyor.
Claim 2
Dependent Claim
264 words
A conveyor assembly, comprising a support structure, a first conveyor mounted on said support structure and being positionable in a substantially vertical position, a supporting frame mounted around said first conveyor adjacent the lower end thereof, said frame and said first conveyor being relatively rotatably movable in respect to each other so that there is a relative rotation about the axis of the first conveyor in respect to said frame, a second conveyor comprising a bucket chain conveyor having an endless chain with a plurality of buckets therealong and being carried on said supporting frame and including a lower reach extending laterally of said first conveyor and below said frame, a guide roller for said second conveyor carried by said supporting frame and being located below and on one side of said first conveyor, and a pivot arm rotatably supporting said deflecting roller and pivoted on said supporting frame to extend outwardly from said frame on the opposite side of said frame from said guide roller, said second conveyor chain being guided over said guide roller and said deflecting roller through a path which may be shifted laterally and vertically by adjustment of the angular position of said pivot arm by pivoting said pivot arm, and means on said supporting frame for pivoting said pivot arm, said second conveyor also including an upper portion located above said supporting frame, and a receiving conveyor located on said supporting frame below the upper portion of said second conveyor in a position to receive material from said buckets and to deliver the material to said first conveyor.
Claim 3
Dependent Claim
68 words
A conveyor assembly, according to claim 1, wherein said support structure comprises a movable crane, a jib supported on said crane, means at the outer end of said jib pivotally supporting said vertical conveyor, said first endless member conveyor including a closed tubular chute having an endless member conveyor elevator operable therethrough and through said jib, means at the inner end of said jib for receiving material therefrom.
Claim 4
Dependent Claim
62 words
A conveyor assembly, according to claim 2, wherein said supporting frame is rotatably mounted at the lower end of said chute, said receiving conveyor being rotatably supported on said supporting frame for rotation around said chute, said second conveyor having a deflecting roller located over said annular conveyor so that the buckets of said second conveyor are emPtied into said annular conveyor.
Claim 5
Dependent Claim
207 words
A conveyor for delivering bulk material from a storage space particularly for unloading ships, comprising means defining a first conveyor adapted to extend generally vertically into the storage space, a support adjacent the lower end of said first conveyor, at least one second conveyor comprising an endless member having buckets therealong and being carried on said support and including a plurality of guide pulleys rotatably mounted on said support, said endless member travelling over said guide pulleys, a third annular conveyor carried by said support and located below at least one of said guide pulleys in a position to receive material from said second conveyor when said endless member and the buckets move thereover, at least one of said guide pulleys being mounted below the bottom end of said first conveyor, a swing arm pivoted to said support for angular movement and having an outer free end, a deflecting pulley rotatably mounted on said swing arm adjacent the outer free end and engaged with said endless member, means to pivot said swing arm to deflect said endless member selectively laterally and downwardly to facilitate the positioning of the buckets so that they may reach the material located both below and to one side of said first conveyor.
Claim 6
Dependent Claim
207 words
A conveyor for delivering bulk material from a storage space particularly for unloading ships, comprising means defining a first conveyor adapted to extend generally vertically into the storage space, a support adjacent the lower end of said first conveyor, at least one second conveyor comprising an endless member having buckets therealong and being carried on said support and including a plurality of guide pulleys rotatably mounted on said support, said endless member travelling over said guide pulleys, a third annular conveyor carried by said support and located below at least one of said guide pulleys in a position to receive material from said second conveyor when said endless member and the buckets move thereover, at least one of said guide pulleys being mounted below the bottom end of said first conveyor, a swing arm pivoted to said support for angular movement and having an outer free end, a deflecting pulley rotatably mounted on said swing arm adjacent the outer free end and engaged with said endless member, means to pivot said swing arm to deflect said endless member selectively laterally and downwardly to facilitate the positioning of the buckets so that they may reach the material located both below and to one side of said first conveyor.
Claim 7
Dependent Claim
15 words
A conveyor according to claim 4, wherein said support is rotatable around said first conveyor.
Claim 8
Dependent Claim
71 words
A conveyor according to claim 4, wherein said support is rotatable around said first conveyor about the axis of said first conveyor, said support having a portion spaced outwardly from the axis of said first conveyor with depending support carrying one of said guide pulleys, said swing arm being pivoted on said support and extending outwardly from said support in an opposite direction to said depending support for said guide pulley.
