    • A pile sizer for reducing the lateral extent or diameter of the upper end of a submerged pile. A vertically extending elongated anchor rod is threadedly secured to the upper end of the submerged pile along the central axis of the latter and an elongated tube is swingably secured to said anchor rod by arms to permit orbital movement of said tube about the centerline of the pile. An elongated shaft is rotatably supported within the tube and is formed with a milling cutter at its lower end for cutting the pile and is connected at its upper end to a motor mounted on the upper end of the tube. The operation of sizing the pile to a predetermined diameter can thus be performed from above the water line.
    • 一种用于减少潜水桩上端横向或直径的桩分选机。 垂直延伸的细长锚杆沿着后者的中心轴线被螺纹地固定到浸没桩的上端,并且细长管通过臂可摆动地固定到所述锚杆上,以允许所述管围绕桩的中心线轨道运动 。 细长轴被可旋转地支撑在管内,并在其下端形成有铣刀,用于切割桩,并且其上端连接到安装在管的上端的马达。 因此,可以从水线上方进行将桩的尺寸调整为规定直径的动作。

    • A safety guard structure including a guard member adapted to be interposed between a mechanism such as a punch press and the operator thereof to protect the operator from injury. In one form of the invention the guiding frame for guiding the guard member between its upper and lower positions is swingably connected to the mechanism to be guarded to permit the entire guiding frame to be swung upwardly so as to present no interference when it is desired to modify the mechanism or to change the dies thereof. In another form of the invention the guide structure for the guard member is entirely positioned above the area to be protected so as to present no interference when it is necessary for operators to work around the machine. An interlocking device is provided to prevent operation of the mechanism except when the guard member and its guide structure are in proper operating position.
    • 一种安全保护结构,包括适于插入诸如冲压机的机构和操作者之间的保护构件,以保护操作者免受伤害。 在本发明的一种形式中,用于引导保护构件在其上部和下部位置之间的引导框架可摆动地连接到待保护的机构,以允许整个引导框架向上摆动,以便当期望不会产生干扰 修改机构或改变其模具。 在本发明的另一形式中,用于防护构件的导向结构完全位于待保护区域上方,以便当操作者需要在机器周围工作时不会产生干扰。 提供一种互锁装置,以防止机构的操作,除非防护件及其导向结构处于正确的操作位置。
