    Abstract: A lip for an excavating bucket has a row of sockets in each of which a respective excavating tooth is mounted, the center of the lip being relieved (i.e., offset with respect to the corners thereof) in two mutually perpendicular planes, such that the corner teeth do the initial excavating without interference from the center teeth, in both forward and lateral movements of the bucket. The combination of the shorter teeth used in the center of the lip plus the relief mentioned causes the corner teeth to engage the working face in advance of the other teeth, in both forward and lateral bucket movements.

    Abstract translation: 用于挖掘铲斗的唇缘具有一排插座,其中每个插座具有相应的挖掘齿,在两个相互垂直的平面中唇部的中心被释放(即,相对于其拐角偏移),使得角部 在铲斗的前后运动中,牙齿进行初始挖掘而不受中心齿的干扰。 在唇部中心使用的较短的牙齿与所提及的浮雕的组合使得角部齿在前进和后部铲斗运动中在其它齿之前啮合工作面。
