Abstract: 190,486. Verdaguer, F. Dec. 22, 1921, [Convention date]. Aeroplanes; planes, arrangement of; propelling; steering and balancing.-A n aeroplane has front and rear biplane wings 2, 2<1>, 4, 4<1>, divided along the e longitudinal vertical plane of the machine and adjustable at will in the same and opposite directions about transverse axes 41, 41<1>, 43 by connections to an elastically and adjustably supported control-plate which allows of an automatic distribution of lifting force on the wings when it is left free. A rudder 29 is coupled to a pair of front steering- wheels 28, which are filled in to act as additional surfaces. Propellers 27, 27<1> are driven by engines 26, 26<1>. The axes 41, 41<1>, 43 are situated at the approximate centres of pressure of the wings, and are supported by struts 21, 21<1> connected to the fuselage by stays 37, 37<1>, one strut being provided to each pair of upper and lower wings which are coupled together to move in unison by links 47, 48. By withdrawing pins 50 the wings may be removed. The lower planes have levers 46, 46<1> connected by links 45, 45<1>. bell crank levers 51, 51<1>, and links 30, 30<1> to a hand wheel 24 universally mounted on a ball 25, Fig. 4. The ball 25 is supported from a sleeve 11 sliding within a sleeve 15 which slides in a part 22<1> on the fuselage. An elastic connection 7 to an adjustable screwed rod 8 tends to raise the ball 25 and press the wheel 24 against stops 17 on the sleeve 15. The sleeve 11 has a closed end 9, bored for the passage of the rod 8, which carries an abutment 10 to prevent undue fall of the wheel 24 should the connection 7 break. When in flight, the air pressure on the wings causes the wheel 24 to be pulled away from the stops 17 against the action of the elastic connection 7, the angle of incidence of the whole of the planes being adjustable simultaneously by raising or lowering the sleeve 15. The sleeve 15 is raised or lowered by a pulley 31 which engages a screw on the outside of the sleeve, the pulley, being turned by a cord 6 controlled by the pilot. Stops 18 and cables 19 limit the upward and downward movement of the wheel 24. The front stops 17, 18 are lower than the rear stops so as to cause the machine to take a downward inclination when they contact with the wheel 24. The links 30, 30<1> are adjustable in length bv nuts 23, 23<1>. and the wheel 24 is elastically held in its normal position by springs 14, 14<1> connected to spindles 13 having adjusting nuts 13<1>. The pilot balances the machine by tilting the wheel 24, but a gust acting on any of the wings is automatically transmitted through the wheel 24 to all the other wings subject to the elastic control of the springs 14, 14<1>. The rudder 29 and the front wheels are operated by a separate rudder bar 34, 35. Land wheels.-The front swivelling-wheels 28 and rear wheels 28' are a considerable distance apart, and the rear wheels are fitted with brakes.
