Abstract
16,156. Adrianoff, W. de, and Bernstein, F. July 13. Magnetic compasses.-A sighting compass' for hand use is provided with a clamp for fixing its rotating parts after an observation has been made, and thus permit exact reading. The base 1, Fig. 2, having a ribbed edge 2 is formed in one piece with the box 3. This box has formed in its outer wall a groove 4, and on its inner side a projection which supports the limbus 5, which is of aluminium or other non-magnetic material. The casing 6 carries a glass disk on its upper side, and has pins 4<1> formed on it which engage in the groove 4 and thus permit rotation. Attached to the casing 6 are two rings 10, 11 of the shape shown in Fig. 3, which can be rotated and are such that when vertical the point a and the point of the notch a<1> are in a plane parallel to the plane of the apparatus. The points a, a' are sighted on the object, and the box 3 is rotated until the zero of the limbus comes under the needle, when it is fixed by rotating the disk 14 which works on a screw-thread attached to the pin 12.
