. X3ZT INCHES O I 2 I â â â t - â -1 . TXT L LlL Fig. 5. Scale drawing of the Type II Recorder seen from in front with part of the towing eye D removed to show the details of the vertical fin assembly hehind. The internal details of the forward casting A and the internal mechanism frame are shown in broken line. For letter references see text. By means of these screws they may be fixed at any desired angle, so that the pitch of the blades may be altered to give varying speeds of revolution in relation to the passing water, and thus a varying speed of winding to the gauze bandings in the internal mechanism. Each section on the gauze may therefore be made to represent one or more miles of sea traversed as A numbered scale is provided on the boss against each blade, so that each may be correctly adjusted by bringing an engraved line on the blade opposite a particular point on the adjacent scale. The boss is drilled to slide on to the propeller shaft to which it is secured by two set screws. The tail end of the propeller shaft is drilled to take a split pin which is inserted as a safety measure. 1 Seep. 495.
