Itis assumed in this example that the car is moving,
  • a further factor in the design of this arrangement is the lever 17. If the probe system could be mounted symmetrically about the central transverse axis of the car this lever would not be required and a simple link between the two probe arms would sufiice. However, since in any recording car there will be more than onersuch set of probes and since only one of these sets could be mounted in-the central position, the other sets have to be arranged either fore craft of the central transverse axis and compensationhas to be provided for the varying distances between the rails as measured along a transverse axis ofthe car as it goes round a curve. Such compensation is provided by connecting the probe arms 11 and 15 at spaced points on the lever 17 which itself is pivotally mounted at its end on the car.

  • the three-point mounting'thus provided for the rod plate assembly ensures that while it is held in the required position it can move relative to the car frame if this frame twists, that is to say if one side of the frame rises or falls relative to the other.
  • the jack carrying the measuring probe is connected by a link 45 with'the freeend of a lever 46 which is pivotally mounted at the other end 47 in a frame 48 carried on the rods 31 to 34, and this link isprovided with a turnbuckle device 49 whereby its length can be adjusted.

  • the link 50 will transmit the movement of the guideprobe 27 to control the positionof the measuring an arrangement, when the car is on a curved section of the track the inclination of the lever 17 with respect to the. central longitudinal axis of the car will change and this will vary the space between the two probes as measured in a direction transversely of the car.
