    Abstract: The linear traversing apparatus (10) includes a lead screw (12) formed from a plurality of lead screw segments (14, 16, 18) which are supported at regular intervals, that is, at the intersection of adjacent lead screw segments, along a span by fixed hollow cylindrical splice points (20, 22). The lead screw segments (14, 16, 18) include external threading which engages the internal threading of a C-shaped spanning nut (28). The C-shaped spanning nut (28) has a circumferential portion removed so that the spanning nut (28) can clear the fixed hollow cylindrical splice points (20, 22) and associated support structure (24, 26) as the spanning nut (28) traverses the lead screw (12) in response to the rotation of the lead screw (12) and the inhibition of rotation of the spanning nut (28). The rotation of the spanning nut (28) is inhibited typically by mechanical communication with an instrument or other device which is engaged by a rail or a slot parallel to the longitudinal axis of rotation of the lead screw (12).

    Abstract translation: 线性移动装置（10）包括由多个导螺杆段（14,16,18）形成的导螺杆（12），该螺杆段以规则的间隔被支撑，即沿相邻的导螺杆段的相交处沿着 通过固定的中空圆柱形接合点（20,22）。 导螺杆段（14,16,18）包括接合C形跨接螺母（28）的内螺纹的外螺纹。 C形跨接螺母（28）具有去除的圆周部分，使得跨越螺母（28）可以将固定的中空圆柱形接合点（20,22）和相关联的支撑结构（24,26）清除为跨接螺母（28） ）响应于导螺杆（12）的旋转并阻止跨接螺母（28）的旋转而横穿导螺杆（12）。 通常通过与平行于导螺杆（12）的纵向旋转轴线的轨道或狭槽接合的仪器或其他装置的机械连通来防止跨接螺母（28）的旋转。
