    摘要： A grindstone or like block of abrasive material is affixed at the lower end of a first support rod slidably received in a vertical sleeve. A second support rod coupled to the sleeve at a right angle thereto is also slidably received in a hollow offset arm at the upper end of an upright standard. An electromagnet is clamped to the standard for releasably mounting the commutator grinder on a desired commutator machine. The commutator grinder is further equipped with an infeed mechanism and a traverse feed mechanism which enable the grindstone or the like to be fed toward and in the traverse direction of the work. The infeed mechanism comprises a handle, worm gearing, and a feed rod screwthreadedly received in a hollow formed axially of the first support rod, such that the rotation imparted from the handle to the feed rod via the worm gearing is translated into the up-anddown motion of the first support rod relative to the sleeve. The traverse feed mechanism also comprises a handle and a feed rod screw-threadedly received in a hollow formed axially of the second support rod, the rotation of the second mentioned feed rod being likewise translated into the back-and-forth motion of the second support rod relative to the offset arm.

    摘要翻译： 研磨材料的磨石或类似块被固定在可滑动地容纳在垂直套筒中的第一支撑杆的下端。 以直角连接到套筒的第二支撑杆也可滑动地容纳在直立标准的上端的空心偏移臂中。 电磁铁被夹紧到标准，以将换向器研磨机可释放地安装在所需的换向器机器上。 换向器研磨机还配备有进给机构和横动进给机构，使得磨石等能够朝着工件的横向方向进给。 进给机构包括手柄，蜗杆传动装置和进给杆，其螺纹地接收在第一支撑杆轴向形成的中空部分中，使得通过蜗轮传动装置从手柄向进给杆施加的旋转被转换成向上 第一支撑杆相对于套筒的下降运动。 横向进给机构还包括手柄和进给杆，该进给杆螺纹地容纳在第二支撑杆的轴向形成的中空部中，第二提及的进给杆的旋转同样被转换成第二支撑件的往复运动 杆相对于偏移臂。

    摘要： This invention relates to a large diameter pipe cutting device for cutting a large diameter steel or cast pipe by moving a cutting machine vertically and bilaterally along the outer periphery of the pipe, said cutting machine including a twoparallelly opposed legged plate support and a cutter driven by an electric motor, said plate support being guided along the outer periphery of the pipe by a bush chain or chains wound tightly on the pipe in a relation forming a vertical plane meeting at right angles with the axis of the pipe.

    摘要： Disclosed herein is an apparatus for removing the imperfect, runout threads in large diameter, internally threaded stud holes. The apparatus comprises a tool-holder assembly provided for automatically locating the thread-grinding tool with respect to the thread to be operated on and means for accurately guiding the tool along a helical path corresponding to that of that thread upon rotation of the tool holder.

    摘要： Apparatus for cleaning the braking surface of a brake disc without dismounting the disc or completely dismantling the brake installation is disclosed. A pair of grinding chocks or pads having a grindstone plaque or layer mounted upon a backing plate via a layer of thermal insulation is substituted for the brakeshoes or is retained against the discs and pressed against the area to be cleaned while the disc is rotated via an auxiliary motor frictionally engaging the periphery of the disc or through the axle of the disc.
