Abstract

28,590. Capone, F. Dec. 30. Aerial machines without aerostats; aeroplanes; cars; propelling; steering; shock of landing, deadening.- The aerial machine is provided with an aeroplane 1, Fig. 1, and is raised by rotary propellers 54, the blades of which are feathered and caused to vibrate. The main part of the apparatus is situated below the aeroplane, to obtain a low centre of gravity. The aeroplane is braced by rods 4, and an horizontal rudder 3 is hinged at the rear of the plane. Sails 11, 12 are placed at the front and rear of the aeroplane, and can be taken in to correct lateral wind pressures. Rollers 91 fixed to the front of the plane lessen the shock of landing. The machine may travel on land, being driven by pedals or by the motor 6. A hood 8 is provided for the aeronaut. The shafts 53 of the propeller blades are mounted on two forks 44, Figs. 5 and 8, which are rotated by a shaft 43 driven from the motor 6. Each of the forks supports a coupling-box 46 on which rings 47 are fixed. Rods 48, 49, provided with rollers 50 engaging with inclined guideways 51, 52, are secured to the rings 47 and serve to turn the propeller blade about its shaft 53 to obtain a feathering motion. The blades also have a vibratory movement about a pivot 60 on the shaft 43, which movement is caused by the engagement of the tail 55 of the wing shaft with a curved guide 56, adjustable by a screw 58, Fig. 7. A similar arrangement may be employed to adjust the guideways 51, 52. Uprights 59, having a curved end, engage with grooves in the forks 44 so as to retain the blades in their proper positions. In order to prevent the coupling-boxes from turning when the rollers are on the flat portions of the guides 51, 52, a catch 29 engages with a rack 30 on the forks 44 ; but when the rollers are on the inclined portions of the guides the catch 29 is freed from the rack.
