An auger drive means is supported on a cross beam at the top of the bowl; and the upper bearing housing and the drive means have generally coaxial opposed square stub shafts which are loosely but non-rotatably engaged by square sockets in the bottom and top of an auger shaf...

An excavating and loading system includes an excavating wheel assembly at the front thereof and a plurality of conveyors for conveying the material from the excavating wheel assembly upward and rearwardly. The excavating wheel assembly includes at least one excavating wheel which is angularly disposed with respect to the direction of travel to form an excavation and has digging surfaces on the forward extending end of the excavating wheel. The wheel forms an excavation wider than the following p...

An underwater mining or dredging apparatus having a supporting vessel and a continuous loop to which is attached a number of containers. In one embodiment, the loop is hollow and has a ballasted fluid in a lower portion while the descending portion is buoyant. This will reduce the likelihood of entanglement of the loop. In another embodiment, a weight sled is used to help gather the underwater aggregates and prevent wear of the loop. The loop may be designed to hydrodynamically resist entangleme...
