Abstract: A power shovel is disclosed for loading and unloading cargo. The bucket includes a first bucket half and a second bucket half wherein each bucket half has a top, a closed bottom, a front wall and a back wall which are spaced apart from each other, a closed outside wall and an open inside. The bucket halves are pivotally secured together at their tops so that the bucket halves are movable between an open and a closed position. In their closed position, the open inside of the bucket halves register with each other so that cargo is contained within the bucket. A head is disposed above the bucket and is attached to the bucket by four elongated cables. Two cables are attached to the outside corners of one bucket half while, similarly, the other two cables are secured to the outside corners of the other bucket half. One end of a closure cable is secured to a winch so that the cable extends through a swivelable pulley assembly, around pulleys in each bucket half, and then exits through a second swivelable pulley assembly. The other end of the closure cable is attached to the crane or a further winch. Upon activation of the winch, the closure cable moves the bucket from its open to its closed position while the swivelable pulley assemblies prevent galling of the cable by the bucket.

Abstract: A clamshell bucket assembly including first and second pivotally connected steel bucket halves rotating between open and closed positions and including sediment retention bars secured between the overlapping sides define a scoop for permitting outflow of water while retaining a volume of a dredged material. Weld rivets provide reinforced securing of the side and bottom steel portions of each bucket half and extend a thickness of the bucket halves to prevent fracturing at the welded interface. Upper and lower sheave assemblies provide increased durability and wear resistance during repetitive opening and closing of the mechanical bucket halves. The sheaves each include a central pin supporting hub collar formed from a plurality of progressively inwardly stepped and stacked disc shaped plates, these being initially sectioned from a hardened steel sheet and welded to form the hub at the highest zone or area of stress exerted upon the sheave during operation of the bucket.

Abstract: A tilt adjustable head attachment assembly for a clamshell style bucket for orienting first and second bucket halves at an angle relative to a length axis extending through an elongated and rigid attachment associated with a piece of power equipment, for supporting and manipulating the bucket. A frame has a three dimensional body, upwardly extending pillar mounts located at upper ends of the body and incorporating support shafts for receiving overlapping hinged locations associated with support arms for each of the first and second clamshell bucket halves. A platen is positioned pivotally arranged between the pillar mounts and includes an upper location engaged by an end projection of the elongated attachment. A cylinder is connected to a fixed underside location of the frame at a first end and to the platen at a second end and, upon being actuated, pivotally displacing the platen to in turn angle the frame and supported clamshell bucket halves relative to the excavator attachment according to a desired orientation.

Abstract: A dredging bucket having a head subassembly including an inner rotatable head and an outer head angularly supported by the inner head between level and tilted orientations. First and second opposing bucket halves supported by the outer head and pivotally actuating between closed and opened positions. A pair of T-links incorporated into spaced apart and coaxial pivot locations defined between the bucket halves, each of the T-links having a central stopping bar which, upon the bucket halves rotating to a maximum degree associated with the opened position, contacting end locations defined in upper edge profiles of the bucket halves in order to prevent further opening rotation.
