    • The invention comprises an improved multiple toothed slotting cutter and cut-off saw which utilizes replaceable and indexable inserts of a novel configuration retained by mechanical fastening means and novel insert locating means. Each insert has a narrow cutting edge and a wide cutting edge and in combination with the locating means can be positioned for a narrow cut at a slightly larger radius than the broad cut. In the preferred embodiment, the inserts are alternately positioned for wide and narrow cut around the periphery of the cutter, thus providing a very efficient configuration for a cut-off saw. When the insert cutting edges are dulled the inserts are merely reversed end for end to provide fresh cutting edges with the same alternating positions.
    • 本发明包括一种改进的多齿开槽切割机和切割锯,其利用由机械紧固装置和新颖的插入定位装置保持的新颖构型的可更换和可转位的插入件。 每个插入件具有窄的切削刃和宽的切削刃,并且与定位装置组合可以定位成比宽切削稍大的半径的窄切削。 在优选实施例中,插入件交替地定位成围绕切割器的周边进行宽而窄的切割,从而为切割锯提供非常有效的构造。 当插入件切削刃变钝时,插入件仅仅是端部的相反端,以提供具有相同交替位置的新鲜切削刃。

    • The invention comprises an improved axially compensating tap driver having a recirculating anti-friction bearing engagement between axially telescoping portions. The bearing race comprises an elongated endless race directly machined in the cylindrical surface of the male portion and a longitudinal channel directly machined in the concentric cylindrical female portion with antifriction bearings interengaging the adjacent opposed longitudinal race surfaces. The telescoping portions are retained together for controlled axial movement and recovery therebetween by elastic means. The bottom of the channel preferably engages the male member thereby providing a substantially full radial support engagement of simple geometry and exceptionally economic manufacture.
    • 本发明包括一种改进的轴向补偿分接头驱动器,其具有在轴向伸缩部分之间的再循环抗摩擦轴承接合。 轴承座圈包括直接加工在阳部件的圆柱形表面中的细长环形座圈和在同心圆柱形阴部分中直接加工的纵向通道,其中抗磨摩擦轴承与相邻的相对的纵向座圈相互接合。 伸缩部分保持在一起,以通过弹性装置来控制其轴向移动和恢复。 通道的底部优选地接合阳构件,从而提供简单几何形状和非常经济的制造的基本上完全的径向支撑接合。

    • An end mill that uses a pair of flat sided diametrically opposed throwaway cutting inserts and is made by cutting a slot opening comparable to the thickness of inserts used, through the end of a shank member and then fixing a slightly thinner anvil locator centrally within the slot opening to provide insert receptive pockets on relatively opposite sides of the tool shank while still retaining a clevis space to be closed by a cross screw to clamp and hold the inserts in place.
