Claim 1
Independent Claim
196 words
In apparatus for mining solid material from the floor of a body of water, a device for collecting said solid material comprising: a. a framework; b. at least two treads adapted to support said framework on said bottom; c. a basket rotatably attached to said framework; d. means, rotatably attached to said framework and concentric with the axis of rotation of said basket, comprising a plurality of circumferentially spaced blades, the inner edges of said blades being spaced from said axis by a distance slightly exceeding the maximum width of said basket, the outer edges of said blades being adapted to penetrate said floor of said body of water during rotation of said blades about said axis; e. means interconnecting means (d) with said treads whereby the peripheral speed of said blades and the peripheral speed of said treads are substantially equal; and f. means, concentric with said axis and having a radius slightly larger than the outer radius of said plurality of blades, comprising a grillwork extending from a point substantially directly under said axis to a point at least slightly higher than said axis and rearwadly thereof relative to the direction of framework advance.
