Abstract
A barge cover is wound on a roller, mounted on a trolley which may be moved from one end to the other end of a barge hold, deploying or taking up the cover as it moves. The cover may then be sealed around the barge coaming in a weather proof manner. The roller is mounted on trolleys so that two men may deploy or take up the cover with only their muscle power, without requiring either special docking facilities or an independent power source.
Claims14
A hold cover and associated deployment mechanism for use on vehicles especially during the storage or transportation of a product, said hold cover and mechanism comprising straight and horizontally oriented tracks adapted to be mounted on opposite sides of said vehicle with a hold for receiving said product between said tracks, said straight tracks adapted to extend linearly along substantially the entire length of said hold on opposite sides of said vehicle, opposing support means mounted on said tracks for movement along each of said tracks, a roller extending between and carried by said opposing support means, a hold cover wound on said roller to be unwound to cover or wound to uncover said hold as said support means moves linerally and longitudinally along said straight horizontal tracks, one end of said cover adapted to be attached to an end of said hold, means for bringing said roller into a weather proof contact with the other end of said hold, and means adapted to be distributed along the length of said hold for securing edges of said cover in a weather proof manner to opposite sides of said hold.
A hold cover and associated deployment mechanism adapted for use on vehicles especially during the storage or transportation of a product, said hold cover and mechanism comprising horizontally oriented tracks adapted to be mounted on opposite sides of said vehicle with a hold for receiving said product between said tracks, said tracks adapted to extend along the length of said hold on opposite sides of said vehicle, opposing support means mounted on said tracks for movement along each of said tracks, a roller extending between and carried by said opposing support means, a hold cover wound on said roller to be unwound to cover or wound to uncover said hold as said support means moves along said tracks, one end of said cover being adapted to be attached to an end of said hold, means for bringing said roller into a weather proof contact with the other end of said hold,
- said support means being an elongated telescoping arm having said roller mounted on one end thereof, the other end of said arm being adapted to be pivotedly attached to said vehicle, means for extending or retracting said telescoping arm during deploying or retracting of the cover in order to raise said roller above an upper surface of said product heaped in said hold for deploying or taking up said cover and for lowering said roller to enable said cover to lay on said upper surface after said cover is deployed, said support means further comprising a hydraulic ram for swinging said arm on said pivot in order to erect or lower said support arm during said deploying or retracting of the cover, and means distributed along the length of said hold for securing edges of said cover in a weather proof manner to opposite sides of said hold.
A barge cover mechanism, said barge having an elongated hold surrounded by a coaming, said mechanism comprising a trolley track adapted to be mounted on each side of said hold, said trolley track being adapted to be attached to and extend along substantially an entire length of said coaming, a trolley for each side of said hold, said trolley being mounted for movement along the length of said track, an elongated support arm for each side of said hold, each of said arms being pivotally mounted on an individually associated trolley to swing between substantially vertical and substantially horizontal positions, a roller extending across said hold and being mounted on said elongated support arms whereby said roller is raised or lowered by swinging said arms between said vertical and horizontal position, said roller having a hold cover wound thereon, and means for deploying or taking up said hold cover while said trolley is moving along said track.
A barge having a hold surrounded by a coaming;
- a roll of sheeting cover material means movably mounted for travel along said barge over an entire length of said hold;
- and manually operably means for deploying said sheeting cover from said roll and over said hold, and bring said roll into a tight weather proof sealing contact against one end of said coaming, or taking up said cover and wrapping it on said roll on an opposite end of said coaming;
- and tracks on said barge which extend along the length of said hold, said roll being mounted on a trolley which travels over said tracks, a hydraulic ram mounted on said trolley for raising or lowering said roll, and telescoping means for further raising or lowering said roll, whereby said hydraulic ram may lower said roll and said telescoping means may pull said roll into said weather proof sealing contact against said coaming.
