Page 249 - Rule three. All ocean-going steamers, and steamers carrying sail, shall, when under way, carry — (A) At the foremast head, a bright white light, of such a character as to be visible on a dark night, with a clear atmosphere, at a distance of at least five miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of twenty points of the compass, and so fixed as to throw the light ten points on each side of the vessel, namely, from right ahead to two points abaft...
Page 249 - ... light, so constructed as to show an unbroken light over an arc of the horizon of twenty points of the compass, so fixed as to throw the light ten points on each side of the vessel, namely, from right ahead to two points abaft the beam on either side, and of such a character as to be visible at a distance of at least five miles.
Page 250 - Here the two colored lights visible to each will indicate their direct approach "head and head" toward each other. In this situation it is a standing rule that both shall direct their courses to starboard and pass on the port side of each other, each having previously given one blast of the whistle.
Page 249 - ... miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of ten points of the compass, and so fixed as to throw the light from right ahead to two points abaft the beam on their respective sides.

They will require to be fitted each with a screen, of wood or canvas, on the inboard side and close to the light, in order to prevent both being seen at the same moment from any direction but that of right ahead to 2 points abaft the beam.
Page 253 - This will be readily understood by a reference to the preceding illustrations, where it will appear evident that in any situation in which two vessels may approach each other in the dark the colored lights will instantly indicate to both the relative course of each; that is, each will know whether the other is approaching directly, or crossing the bows either to starboard or port. This intimation, with the signals by whistle, as provided, is all that is required to enable vessels to pass each other...
Page 238 - ... premature ignition. The carbon from the oil will deposit on the head of the piston in cakes and lumps, and will not only increase the compression but will get hot after running a short time and will ignite the charge too early, and thereby produce the same effect as advancing the spark too much. If this is the cause the pounding will cease as soon as the carbon deposit is removed from the combustion chamber. Badly worn or broken piston-rings. Improper valve seating. A badly worn piston. Piston...
Page 250 - SITUATION In this situation the red light only will be visible to each, the screens preventing the green lights from being seen. Both vessels are evidently passing to port of each other, which is rulable in this situation, each pilot having previously signified his intention by one blast of the whistle. THIRD SITUATION...
