    • A mechanism for moving a cross slide in a multiple-spindle automatic machine has a rotary face cam which is driven by a gear and is angularly adjustable with respect to the gear, a first lever which is pivotable on a first shaft parallel to the axis of the cam and which has a first arm carrying a roller follower for the cam and a second arm having a slot for a sliding block which is mounted on a pin-shaped carrier. The carrier extends through one or more slots of a second lever which is rigid with a second shaft, and the carrier can be fixed to the second shaft in a selected position by means of washers and nuts. The second shaft is rigid with a gear segment which meshes with a toothed rack affixed to and adjustable lengthwise of the slide. The first lever may be a bell crank lever or a straight two-armed lever, and the second lever may have a single arm with a single slot for the carrier of the sliding block or a bifurcated arm with two aligned slots for the carrier.
    • 用于在多主轴自动机器中移动十字滑块的机构具有旋转面凸轮,该旋转面凸轮由齿轮驱动并且可相对于齿轮成角度地调节;第一杆,其可在平行于 凸轮,其具有承载用于凸轮的滚子从动件的第一臂和具有安装在销状托架上的用于滑块的槽的第二臂。 托架通过与第二轴刚性的第二杆的一个或多个槽延伸,并且托架可以通过垫圈和螺母在选定位置固定到第二轴。 第二轴是刚性的,齿轮段与固定在滑块的纵向可调节的齿形齿条啮合。 第一杠杆可以是曲柄杠杆或直的二臂杆,并且第二杆可以具有单个臂,其具有用于滑块的承载件的单个槽或具有用于承载件的两个对准槽的分叉臂。
