MARCH 14, 1918. AN ALBATROS FIGHTING BIPLANE. Continued from page 255.) THE cockpits of the Albatros are arranged in the fashion now universally adopted for two seaters, by Allies as well as by the enemy, i.e., the pilot in front and the gunner in the rear cockpit. The pilot's seat is mounted, in the Albatros, on the main petrol tank, which has two annexes on top, one on each side of the seat. This arrangement is clearly indicated in Fig 12, in which the small clips preventing the seat from sliding about on the tank will be noticed. The filler cap is mounted on a tubular projection extending through the fuselage covering, thus enabling the tank to be refilled from the outside. A smaller auxiliary tank is mounted above and to the rear of the main tank, in the the gunner's cockpit, as a matter of fact. Both tanks are connected up to a by-pass or distri- butor, so that both or either tank can be connected up to the engine, two pumps being provided for maintaining the necessary pressure, one driven by the engine and the other hand operated. Thus, whatever tank is being used, petrol is fed to the carburettor under pressure. This has probably been a necessary provision, as the tanks are placed relatively low and gravity feed would, therefore, be apt to be unreliable when the machine is climbing at a fairly steep angle. Constructionally the petrol tanks are of interest in that they have been internally braced by rods running across from side to side, the attachment of the rods being visible on the outside of the tank as shown in Fig. 12 (p. 285).

In the top left-hand corner is shown the pulley over which the elevator cable passes after leaving the crank lever on the rocking shaft (see Fig. 13). The pulley in the top right-hand corner isbolted to the middle longeron just ahead of the tail plane, and serves to guide the elevator cable. In the bottom left-hand corner is shown the pulley mounted on the top longeron in front of the tail plane, overwhich passes the elevator control cable, and the pulley shown in the bottom right-hand corner guides the rudder cable in front of the foot bar, where its direction changes from a lateral to a longitudinal one. 286
