Abstract

16,529. Dillberg, G., and Petersson, C. July 15. Course recording apparatus.-The compass-card u, disk c, arithmetical spiral d, and the braking-disk e moving in an oil-bath g are all firm on the spindle b, so that when, by means of clock-work, the disk b is intermittently held fast by the brake-surfaces r and the arm h is released from the action of the cam o so as to be free to move under the influence of the spring p, this arm h moves in till the pin k contacts with some point of the spiral, the inner end of the line thus drawn on the travelling-sheet m by the marking-point l then giving the momentary course steered.
