    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).
