摘要： A tapered thread cutting machine includes a multi-part rotary machining head, one part including a through-recess and another being a separable interior wear plate. Interacting chaser holders are mounted in the recess and include angled V-shaped slots in which block type chasers may be secured between clamps and locating pins enabling the chasers to be removed and replaced without removing the holders from the recess. The holders are driven by a linear cam for opening and closing movement through a thrust block mounted on a guide rod, such thrust block being fitted in a slot in one holder but otherwise not secured thereto so that binding in the opening and closing of tool holders is minimized.

摘要： A ground rod, coupling therefor and method of making that coupling are disclosed providing both strength and improved conductivity. Ground rods are usually copper coated or plated steel rods formed in sections which are driven or, perhaps more correctly, pounded into the ground to form grounding or earthing connections for dissipation of electrical current into the earth. The coupling includes co-extensive inner and outer sleeves of copper and a corrosion resistant metal such as stainless steel, respectively, which are mechanically interlocked along their axial lengths. The inner copper sleeve is formed with threads or oppositely directed cones after the two sleeves are interlocked and in so doing the interlock between the sleeves is enhanced. If the connection of the coupling to the rod is threaded or a simple cone friction fit, the connection and/or driving of the rod sections yet further works the internal copper sleeve enhancing both copper-to-copper electrical conductivity and the interlock of the inner and outer sleeves.
摘要翻译： 公开了一种接地棒，其联接器和制造该联接器的方法，提供了强度和改善的导电性。 接地棒通常是铜或镀钢钢棒，形成在被驱动或可能更正确地撞击到地面中的部分中，以形成用于将电流耗散到地球中的接地或接地连接。 联轴器分别包括铜的共同内部和外部套筒以及耐腐蚀金属（例如不锈钢），它们沿其轴向长度机械联锁。 在两个套筒互锁之后，内部铜套筒形成有螺纹或相对定向的锥体，并且这样做使得套筒之间的互锁被增强。 如果联接器与杆的连接是螺纹或简单的锥形摩擦配合，则杆部分的连接和/或驱动进一步工作在内部铜套筒上，从而增强铜对铜的导电性和内部 和外套。

摘要： A machine and process for forming a high strength precision bar joint and more particularly for forming rolled tapered threads on a bar end such as the tapered end of a reinforcing bar used in concrete construction. Such machine and process employs opposed oppositely rotating die disks which have conical opposed die surfaces. A thread form die is provided on the conical die surfaces in the form of thread form spirals which bear against the opposite sides of the tapered bar surface as the die disks rotate. The die surfaces include opposed recesses into which the bar end is inserted. The bar may be held for rotation against a stop as the die disks oppositely rotate. Alternatively the bar end may be held against rotation and the die disks orbited around the bar end as the die disks oppositely rotate. A tapered surface is formed on the bar end prior to roll forming of such threads as by hot or cold forging or by cutting. The bar is held by a transfer vice for transfer from the tapered surface forming operation to the thread rolling operation to ensure that the tapered surface is properly centered while the threads are formed.
摘要翻译： 用于形成高强度精密棒接头的机器和方法，更具体地说，用于在诸如用于混凝土结构的钢筋的锥形端部的杆端上形成轧制锥形螺纹。 这种机器和工艺采用具有锥形相对的模具表面的相对的相反的旋转模具盘。 螺纹成形模具以锥形螺旋形式设置在圆锥形模具表面上，螺纹形螺纹在模盘旋转时抵靠着锥形杆表面的相对侧。 模具表面包括杆端部插入其中的相对凹部。 当模具盘相对旋转时，杆可以保持用于旋转而停止。 或者，杆端可以保持抵抗旋转，并且当模盘相对旋转时，模具盘围绕杆端部旋转。 在通过热或冷锻造或通过切割进行这种螺纹的辊轧成型之前，在杆端部上形成锥形表面。 该条由转印件保持，用于从锥形表面成形操作转移到螺纹滚动操作，以确保锥形表面在形成螺纹时适当地居中。

摘要： A ground rod electrical connection bracket (10) includes a bent sheet metal receiving member (12), the end (13) of which are bent into opposed semi-cylindrical shapes and provided with screw threads (18). The ends (13) are provided with a rim (19) and by pinching the ends, a ring (14) may be positioned behind the rim around the semi-cylindrical ends. A corrosion resistant bolt (17) engages the screw threads to clamp a connecting wire (16) against the ground rod (15). The connecting wire is seated between the ground rod and an acute corner (22) of the receiving member.
