Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed July 24, 1918. Serial No. 110,850.

To all whom it me concern:

Be it known t at I, Fnnmuco Caraom, a subject of the King of Italy, and resident of 28 Via S. Gregorio, Milan, Italy, have invented certain new and useful Improvements inFlying-Machines, of which the following is a specification.

The object the invention IS the constructiomof a multiplane flying machine of great power and efficiency and capable of maintaining great stability in the air and also permitting of easy landing.

The improvements are connected wlth the arrangement of the engines, the sustaining planes, the landing carriage frame and details of constructions of such mentioned various parts of the apparatus.

In the annexed drawing is re resented by way of example a triplane em odying the improvements that form the object o the present invention.

Figures 1, 2 and 3 represent respectively a front elevation, a plan view and a side elevation of a triplane;

Figs. 4 and 5 represent on a larger scale a side View and a plan view of an essential part of the landing carriage;

Fig. 6 is a detziil view of a portion of said carriage on a larger scale.

The triplane comprises two fuselages 1, 2, symn'ietrically arranged with res set to the center line of the ap aratus. Suc 'fuselages are fixed by their ore-ends to the forward body formed b sustaining planes 4, 5, 6. At the rear on of the fuselages 1, 2, are mounted the following planes: A tail plane 7, a horizontal'rudder 3, rotatably coni nected to the horizontal axle 8, three vertical rudders 9, rotatably mounted on axle 10 and joined to one another by means of wires 11, with the view to realizing a simultaneous rotation of same.

The rudder 9 is,' operated by means of wires 12 which extend to points ad'acent the aviators seat where suitable mcc anism is provided for operating the wires. The ruder 3 is operated in a similar way by wires not shown.

The arrangement of the planes 4, 5,

6 is secured by means of two kinds of uprights 13 and 14, arranged in two rows respectively on the front and on the rear of the forward body. The uprights 13 are fixed by their ends 15, 16 respectively to the forward longitudinal frames of the planes 4 and 6 and at tached at their center to the plane 5. The

uprights 14 are connected at their centers 17 to the rear longitudinal frames of the central plane 5, and by their ends 17 to the longitudinal frames of the planes 4, 6.

On metallic cross-pieces at the points 15 and 17 are joined the stays 18 forming the diagonal members of the chassis of the for ward body.

The angles of incidence of the lanes 4, 5, 6, and their curvatures are di erent and established in such a way as to obtain a convenient distribution of the pression and depressions on said planes.

The angle of incidence of the upper plane 4 is smaller than that of the lower plane 6, and the intermediate plane 5 has an angle of incidence comprised between those of the other two. Moreover, the curvature on the back of surface shall be such as to cause the highest depression, while the curvature underneath the'surface 6 shall be such as to cause the highest compression.

The car 19 is mounted through the front body and comprises the aviator-seat, the control devices and rearward the motor 20 driving the propeller 21. Two furthermotors 22, 23, are arranged on the forward ends of the fuselages 1, 2, which ends project outside the front frame.

The motors 22, 23, are connected directly to-the pro ellers 24, 2 5.

The an ing carriage comprises three sets of wheels 26, 27, 28. The sets 26, 27, are alike and are mounted underneath the front body symmetricall arranged in respect to the central line of the apparatus, and the uprights 14 and fuselages 1, 2. The frames 0 such sets of wheels are so constructed as to distribute the several strains caused by landing and besides to reduce the resistance of air to progressive movement. The fitting up of wheels on their frames is effected by suitable elastic means in order to have a convenient elastic reaction to the strains caused by landing.

The frames 29 are so made of compound wood that they will be free from distortion and are fiat in form. Said flat frame is fixed its upper end to longitudinal frame 30 32 by means of upright 33. Between the longitudinal frames 30 and 32 and the center of arm 31 are rigidly arranged the strengthening bars 34, 35.

The axles, 36 37 of the two couples of wheels 38, 39 (Fi 5) are sup orted at their centers by arm-'3 and are tie up by cables or elastic bands, preferably consisting of caoutehouc, The axles 36, 37, are connected to one another by means of metallic rods 42, through a joint, such rods being surrounded by elastic bands 43 that tie them up to arms 31. The fore axle 36 is connected by means of rods 44 to the ends of a rocking member 45, such member bei-n connected by its center through a joint 6 to support 47, fixed on the curved part of frame 29.

Underneath each rod 42 is arran ed a stay 48, as well as an extensible uprig t 49, such arrangement having for its 0b ect to conveniently distribute strains onsaid rod.

The chassis of the landing carriage comprises further a forward pair of wheels 28 their axle 51 being elastically connected to frame 52. Frame 52, formed as a doublearmed lever, is connected to a.suppo rt1n g body of which the main upright 54 1S elastically connected to the upper end of frame 52 by means of elastic ties 55; 56 1s a stay to balance the strain on the elastic tie 55 caused by landing.

The rear skid.57 is joined to frame 58 in the same way as frame 52 to the body .53, 54,

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare that what I claim is 1. A multigil'ane flying machine comprising in com ination two fuselages symmetrically arranged with respect to the center line of the apparatus, two motors arranged on the forward ends of said fuselages, propellers attached to said motors, a tail plane and a horizontal rudder mounted at the rear end of said fuselages, three vertical rudders rotatably mounted at the rear end of said fuselages and means to rotate said vertical rudders simultaneously; afront body consisting of three lanes arranged one above the other and w erein the angle of incidence of the upper plane is smaller than that of the lower plane and the middle lane has an an 1e of incidence comprised beween those of t e others, two series of uprights for securing the said arrangement of the planes arranged in two rows respectively on the front an on the regrof the said forward body, the first row of upri hts havin their ends fixed respectively to t e forwar longitudinal frames of the upper and lower lane and their center attached to the middle plane, the second row of upri hts havin one end connected to the rear ongitudina frames of the central plane and havin the other ends connected to the longitu inal frames of the upper and lower planes, diagonal members consisting of stay wires, metallic cross pieces for fixing stay wires so that they adjoin the ends of said uprights, a car mounted through the front body and comprising the aviator seat, the control devices, and rearward a third motor on said car driving a propeller.

2. A landing carriage for a multiplane flying machine comprising in combination a chassis formed of compound wood which is fiat in form and constitutes a frame, three sets of wheels to said chassis, two sets being alike, a lower frame curved rearward and formed into an arm, longitudinal members on the chassis, an upright for connecting the said arm to one of sa1d longitudinal members, strengthening bars rigidly arranged between said arm and said longitudinal members of the chassis, axles for the two sets of wheels, bearings for said axles on the center part of the frame arm, metallic rods connecting said axles to one another, elastic bands for connecting to ther the frame, the axles and the metallic rods, a rocking member on the frame, rods connecting said member to the fore axle, a support fixed 'on the flat frame and connected at its center through a joint to the said rockin member, a sta member underneath eac metal ic rods, an upright member for stretching said stay, a frame for the third pair of wheels in the form of a double armed lever, means for connecting the axle of the said wheels elastically thereto, a supporting bod connected to the said frame a main u rig t on the said body, means for elastica 1y connecting the u per end of the said double armed lever to the main upright and a stay to balance the strain on the said elastic connection.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses FEDERICO CAPRONI.
