Abstract

17,388. Hennah, W. H., and Rissel, A. K. W. July 26. Course-recording apparatus.-Should the ship deviate from its course, one of a series of points c on the compass card contacts with one of two terminals g, h to close the circuit of one of the two relays ,j, k and thus energize one of the magnets p, r, which acts on the corresponding disk w or r to cause a braking action in one of the two sets of gearing t, u, so that differential action takes place and the shaft 4 is positively rotated; the indicating-arm 5 moves over the recording-drum, therefore showing that deviation has taken place. If this deviation is continued for a certain time, or increases to a predetermined extent, the end of the arm 5 contacts with a stop 9 or 10 to complete circuit and give an alarm.
