Abstract
1,188,536. Measuring length. MARCONI CO. Ltd. May 25, 1967 [Aug. 25, 1966], No.38207/66. Heading G1M. In a length measuring apparatus a wire anchored to a reference point at one end, extends at the other end through a hollow screw 3 to be clamped in a chuck mounted at the end of the actuating shaft 5 of a dial indicator 6 which is mounted on a slidable carriage 8. A spring 13 surrounds the other end of the actuating shaft 5 and lies compressed between the indicator 6 and a plate disc 12 which contacts the end piece 19 of the actuating shaft of a further slidably mounted dial indicator 14. In use, the wire is attached to the reference point and the end piece 20 checked on a point at the required distance from the reference point to zero the indicator dials. The piece 20 is then moved to another point on the surface of a radioreflector, and, if necessary, screw 3 is adjusted to bring indicator 6 to its zero point (thus ensuring the same tension in the wire as before) and then any difference in the reading of dial 14 indicates the difference between the distances from the reference point to each of the two points where piece 20 was applied.
