Description: Patent for a new and improved dredging-scraper. This design "has for its object the production of a marine plow which shall serve to raise and remove obstructions and accumulations from the beds or channels of rivers, bays, harbors, and other water-courses; and the invention consists in a device for this purpose of novel construction . . . The plow, which is to be drawn over the bed of the water-course to be cleared—as, for instance, by drag chain or cable attached to a steamboat—operates to raise a few inches in depth of the deposit each time it passes over the bed or bottom of the water-course" (lines 9-22).
