NOVEMBKR:29, I913. smaller without danger of interference, or, in other words, for the same gap and chord a greater lift is obtained. Two pairs of A struts of spruce connect the main planes and the fuselage. Four more pairs of struts connect the planes in the usual way, whilst near the tip of the lower wing is a single strut running to the rear spar of the upper plane. From the joint of this single strut to the lower plane a steel tube runs up to the leading edge of the upper plane. Very stout stranded cable is used for the diagonal bracing of the wings as well as for taking the drift. Other cables run from the/use/age at a . point near the beginning of the tail plane to the _ inter-plane struts, thus bracing the wings back wards to the fuse/age. (/JJGHT] are, comparatively close to the main planes. The chassis is of the wheel and skid type, with two stout ash skids supported on three pairs of struts of spruce. A " Flight " Copyright One of the elevator crank levers on the H.P. biplane. One of the accompanying illustrations is a diagram matic sketch of the fuselage, and shows the shape of that structure. Constructionally it consists of four longerons ot ash connected by struts and cross-members of spruce, the whole being made rigid by means of the usual diagonal cross bracing. To a steel capping plate bolted to the front of the four longerons is secured the engine— a 100 h.p. 10-cyl. Anzani, which drives an Integral pro peller of 8 ft. 6 ins. diameter, 5 ft. 6 ins. pitch. The pilot's and passenger's seats are arranged tandem fashion, the pilot occupying the rear seat. Both seats are supported on the lower longerons, and the legs of the occupants project down into the boat-shaped structure underneath the fuselage. One of our sketches illustrates the controls, " flight" Copyright. The tail skid of the H.P. biplane. single axle carrying the wheels is slung from the skids by means of rubber shock absorbers, and two radius rods from the front struts to the axle keep the latter in place. Diagonal cross wiring and cables running to the lower extremities of the two first pairs of the inter-plane struts prevent the chassis from giving laterally. A short strong ash skid protects the tail planes against contact with the ground. In front of the pilot is to be fitted a dashboard with all the usual instruments, such as aneroid, clock, compass, revolution indicator, and air-speed indicator. The tanks contain sufficient petrol and oil for a four hours' flight, and the weight of the machine with this and pilot and passenger is 1,775 lbs. The speed of the machine has not yet been ascertained, but she appears to be fairly fast, and seems to climb very well. She has been designed for exhibition work, and the conditions to be fulfilled are good climbing capacity—in order to be able to get out of "Flight" Copyrigl;!. DiaRrammatic sketch of the fuselage, and on the right the tail planes on the H.P. biplane. which consist of a rotatable hand wheel operating the elevator and ailerons, and a foot-bar for actuating the rudder. The tail planes, it will be noticed, are similar to those on the monoplane, and are made of ample size in order to render them more effective, situated as they small fields—and slow landing speed. The machine has been built for an exhibition company in the north ot England, and as soon as she has been put through her trials by Mr. Wbitehouse, she will be delivered to the purchasers. 1299
