Abstract
A carry scraper ship having a tug lighter for towing, a device for scraping and lifting earth and sand accumulated on ground under water, a bucket conveyor for conveying earth and sand scraped and lifted from ground under water to an atmospheric environment above water, a belt conveyor lighter for discharging earth and sand conveyed from under water to the atmospheric environment onto earth carriers, and a structure for linking the tug lighter, the device for scraping and lifting, the bucket conveyor and the belt conveyor light together in operative relationship.
Claims17
A carry scraper ship comprising:
- a device for scraping and lifting earth and sand accumulated on ground under water;
- a tug lighter having means thereon for bearing against ground under water to thereby advance the tug lighter and tow the device for scraping and lifting,
- said bearing means comprising an elongate element with a length and a drive mechanism for angularly reorienting the length of the elongate element relative to the tug lighter both with and without the bearing means bearing against ground;
- a bucket conveyor for conveying earth and sand scraped and lifted from ground under water to an atmospheric environment above water;
- a belt conveyor lighter for discharging earth and sand conveyed from under water to the atmospheric environment onto earth carriers;
- and
- means for linking the tug lighter, the device for scraping and lifting, the bucket conveyor, and the belt conveyor lighter together in operative relationship.

A carry scraper ship comprising:
- a tug lighter having steel rods thereon that can be raised and lowered and swung relative to the tug lighter, there being an oil-pressurized winch to which the steel rods are connected, said oil-pressurized winch set on a box that is slidable relative to the tug lighter, with there being an oil-pressurized cylinder operatively connected to the box;
- a device for scraping and lifting earth and sand accumulated on ground under water;
- a bucket conveyor separate from the device for scraping and lifting for conveying earth and sand scraped and lifted from ground under water to an atmospheric environment above water;
- a belt conveyor lighter separate from the device for scraping and lifting for discharging earth and sand conveyed from under water to the atmospheric environment onto earth carriers;
- and
- means for linking the tug lighter, the device for scraping and lifting, the bucket conveyor, and the belt conveyor lighter together in operative relationship.

A carry scraper ship comprising:
- a tug lighter for towing;
- a device for scraping and lifting earth and sand accumulated on ground under water, said device for scraping and lifting having a front and rear and a replaceable blade at the front of the device for scraping and lifting having a squared scraper to engage ground under water, said device for scraping and lifting further having lifting bases inclined from front to rear and covers for the lifting bases;
- a bucket conveyor separate from the device for scraping and lifting for receiving from the device for scraping and lifting earth and sand scraped and lifted from ground under water by the device for scraping and lifting and conveying earth and sand scraped and lifted from ground under water to an atmospheric environment above water;
- a belt conveyor lighter for discharging earth and sand conveyed from under water to the atmospheric environment onto earth carriers;
- and
- means for linking the tug lighter, the device for scraping and lifting, the bucket conveyor, and the belt conveyor lighter together in operative relationship.
3 more elements
A carry scraper ship comprising:
- a tug lighter having steel rods that can ascend and descend relative to the tug lighter and are operatively connected to an oil-pressurized winch that is in turn connected to a sliding box operatively connected to an oil-pressurized cylinder;
- a device for scraping and lifting earth and sand accumulated on ground under water, said device for scraping and lifting having a front and rear and lifting bases that incline between the front and rear of the device for scraping and lifting, there further being covers each with spaced openings for the lifting bases so that earth and sand being lifted by the lifting bases passes into one of the spaced openings to and out of the other of the spaced openings in the covers and is substantially covered between the openings in each of the covers;
- a bucket conveyor for conveying earth and sand scraped and lifted from ground under water to an atmospheric environment above water;
- and
- a belt conveyor lighter for discharging earth and sand conveyed from under water to the atmospheric environment onto earth carriers.
