Abstract: A tool retrieves material from a well. The tool has a cylindrical tool body, malleable members, and a cylindrical jacket. The tool body defines a chamber adapted to receive material for retrieval. The malleable members are on the lower end of the tool body and preferably are made of a relatively hard, tough malleable material such as steel. They are bendable from an open position allowing material to enter the chamber to a closed position capturing the material. The jacket is mounted on the exterior of the tool body and has a mill surface which is adapted to bend the malleable members from the open position to the closed position. Relative axial movement of the jacket and the tool body causes the malleable members to bear on the mill surface and bend to the closed position.

Abstract translation: 用于从井中检索材料的工具。 该工具具有圆柱形工具主体，可锻制构件和圆柱形外套。 工具主体限定适于接收用于检索的材料的室。 可锻制构件位于工具主体的下端，并且优选地由相对硬的韧性有韧性的材料制成，例如钢。 它们可以从打开位置弯曲，允许材料进入腔室到捕获材料的闭合位置。 护套安装在工具主体的外部，并且具有适于将可延展构件从打开位置弯曲到关闭位置的铣削表面。 护套和工具主体的相对轴向运动导致韧性部件承受在磨机表面上并弯曲到关闭位置。
