Abstract: An excavating machine has a stick arm to which is connected a bucket assembly. The bucket assembly has a bucket which is openable and closable by means of fluid pressure applied to one and the other end of a cylinder. The assembly includes a joint which allows free rotation of the bucket through 360* relative to the stick arm, meanwhile providing that the fluid pressure may pass through the joint to one or the other side of the cylinder, irrespective of the rotative position of the bucket. Fluid pressure is supplied to the joint through hose couplings which themselves allow a degree of pivoting of the hose ends relative to the joint. However, the design of the joint provides that these hose ends do not rotate with the bucket as the bucket is pivoted. A valving system is included for providing rapid opening of the bucket, and stops are associated with the bucket to limit the opening movement thereof. A cushion stop is provided to cushion the movement of the bucket assembly toward the stick arm.
Abstract translation: 挖掘机具有一个连接有铲斗组件的杆臂。 铲斗组件具有通过施加到气缸的一端和另一端的流体压力可开启和关闭的铲斗。 组件包括一个接头，该接头允许铲斗相对于杆臂自由旋转360度，同时提供流体压力可以通过接头到达气缸的一侧或另一侧，而与铲斗的旋转位置无关 。 流体压力通过软管接头提供给接头，这些接头本身允许软管端部相对于接头的一定程度的枢转。 然而，接头的设计提供了当铲斗枢转时，这些软管端部不会与铲斗一起旋转。 包括用于提供铲斗快速打开的阀门系统，并且止动件与铲斗相关联以限制其开启运动。 提供缓冲止动件以缓冲铲斗组件朝向手臂的运动。

Abstract: A clamshell bucket assembly includes a joint which allows free rotation of the bucket through 360*, meanwhile providing that fluid pressure may pass through the joint to one or the other side of a cylinder for opening and closing the bucket, irrespective of the rotative position of the bucket. The joint includes a tubular member and a shaft rotatable within the tubular member, and a fixed frame is included for generally fixing the tubular member in position relative to such frame.
