LOMBARDI FLYING MACHINE Filed Jan. 28,. 1928 4 Sheets-Sheet 4 0/20; amn- Patented Dec. 10, 1929 LAMBERTO LOMBARDI, OF ROME, ITALY FLYING MACHINE Application filed January as, 1928. Serial No. 250,291.

This invention relates to flying machines say, that they may be set horizontally or vertically or at any intermediate angle withthe horizontal, the first position being used when flying, the second one at starting or descend- 3 ing vertically, the third one when it should be desired to fly up in a more or less inclined direction.

According to this invention the wings, motors and screws constitute a unique block V or unity that can rotate an angle of 90 degrees around an axis normal to the longitudinal axis of the body of the flying machine. This rotation permitting the wings to take, as already said, a horizontal position, a vertical or an intermediate position, whilst the motors and screws remain in an unchanged relation with the position of the wings.

The invention will be better understood with reference to the accompanying drawings, in which Figure 1 is a left side view of the machine when flying,

Figure 2 being a front view of same,

Figure 3 is a left side view showing the 30 block of wings, screws and motor rotated 90 degrees, that is, with the wings in a vertical position, the screws being of course in a horizontal plane, I

Figure 4 is a top plan view of the whole machine, 4

Figure 5 is a view of one of the wheels by means of which the rotation of the block is operated,

Figure 6 shows a detail of the operating wheel of Fig. 5,

Figure 7 is a plan view of one of the vertical rudders, v

Figure 8 is a front View showing the relati ve arrangement of the motors and operating wheels, w

Figures 9, and 11 show a modified form of the block operating device in which the wheels are suppressed and the rotation of the block takes place on a central shaft supporting arrangement,

Figure 12 shows the sector that transmits the rotatory movement to the block.

Mounted fixedly on a keelson or body 1, which on the drawings has been represented as of the floating type, but that may obviously be of any type whatever, is a standing double support 2, each support being U shaped, the upstanding legs being connected to one another by a half circular band or guideway 3, so made that inside each guideway 3 a wheel 4 may freely rotate, said rotation being made easy by rollers or the like not shown in the drawings. On the shaft 5 of said wheels 4, the whole block of the wings, motors and screws is conveniently mounted as better seen in Fig. .8, in which however the wings and screws are not represented.

As shown in the figures, 6 are the wing supporting arms; 7 are the motors; '8 the screw shafts; 9 the screws; 10 are the drums or circular casingsinside of which the screws rotate 11 are the wings, the flying machine being preferably of the double deck system.

With hydroplane type of flying machines according to this invention, four floating bodies (two on each side) as 12 and 12 are added, these being intended to balance the machine when afloat, both with the wings in the horizontal and vertical position, such floating bodies being of course dispensed with on over land flying machine.

At both sides of the block is mounted a vertical rudder 13, and a tail horizontal rudder 16 is hingedly fixed to the machine as in ordinary cases.

The peculiar and substantial features of the flying machine according to this invention are Firstly, that, as stated above, the wings, motors and screws are connected in a unique block rotatably mounted on the machine body, so as to take any desired position with respect to a horizontal plane, so that, when the wings are set vertically theyoppose no resistance to the raising of the machine, which however can be raised vertically under the action of the screws that work in this case as lifting propellers, and besides, when flying, said wings can be set at any desired angle in order 100 to fly at that angle,

Secondly, that the propelling screws are enclosed each in an annular casing of convenient height which prevent the air sucked by the screws from escaping laterally, so that the screwing effect of the propellers in the air is fully utilized both for horizontal and vertical propulsion, the latter permitting the machine to vertically move upwards and downwards. The flying machine according to this invention is apt therefore to start in a vertical or inclined direction necessitating no starting run on the ground or the water nor any large spaces before it on landing or descending aground or on the water.

A horizontal rudder 16 apt to take any desired position in respect to the horizontal, is added to the machine, as usual in any other flying machine.

Having now described and ascertained the nature of myinvention and in what manner it is to be performed, I declare that what I claim is:

1. In a flying machine, a main body, uprights on said body, guides carried by said uprights, wheels mounted to turn in said guides, planes carried by said wheels, a shaft connecting said wheels, and propelling motors supported by the shaft outwardly of the wheels.

2. An aeroplane (a as claimed in claim 1, characterized by the provision of floating bodies carried by the planes and arranged in sets, one set being operable when the planes are in a horizontal and the other set when the planes are in a vertical position.

3. In a flying machine, a main body, uprights on the body, guides carried by said uprights, planes mounted to turn in said guides, propelling motors mounted to turn with the planes, and floating bodies carried by the planes and arranged in sets, one set being operable when the planes are in a horizontal and the other set when the planes are in avertical position. y

In testimony whereof I have aflixed my signature.

LAMBERTO LOMBARDI.
