AEROPLAN E Application filed November 13, 1929. Serial No. 406,746.

Another object of my invention is the provision of an aeroplane of simple and 1nex-.

pensive construction, yet durable and efiicient in its operatlon.

A further ob ect of the invention is the provision of a sul. stantiall v square shaped aeroplane equipped with a stabilizing plane or wing, and horizontal and elevation steering means and with ailerons for controlling the rolling motion of the plane and braking its landing force, as well as a pontoon for floating on water.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds,

as and will then be specifically defined in the .appended claims.

In the accompanying drawings, forming a material part of this disclosure:

Fig. 1 is a top plan view of an aeroplane 3g constructed according to my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a fragmentary sectional top plan view of the plane illustrating the wing operating mechanism on a somewhat enlarged scale, with wings spread. I

Fig. 4 is a front end elevation thereof with the wings closed.

Fig. 5 is a sectional detail top plan view of the rear landing gear, and triangular pontoon for floating on water.

Fig. 6 is a perspective view of the wings.

As illustrated, the body of the aeroplane in form of a cabin 10, has at its front one starting and landing wheel 11 and at its rear landing and starting wheels 12 at the ends of an axle 13 journaled in a bearing formed by a. substantially triangularly shaped pontoon 14.

A stabilizing plane or wing 15 has the cus- 60 tomary rudders l6 pivoted to vertical pins 17 provided at the rear end thereof, while an elevation rudder is indicated at 18 and ailerons at 19. i

A pair of triangular wings 20, 21, having a suitably curved body are at their inner meeting edges secured on rods 22, 23, the straight front ends of which project from the wings while their rear ends are somewhat curverh'as at 24, and then end in straight extremities 25 journaled in suitable bearings it? on the aeroplanes fuselage.

The straight front ends carry gears 27,28,

and in front of them the ends of shafts orrods 22. 22' are united by a member 29 the front end of which is pivotally secured, as at 3t), to the lip of a sleeve 31, provided with inner thread adapted to engage the threads of a transverse bar 32 carrying a hand wheel 33.

The gear 27 is also in mesh with a larger gear ill on a shaft 35 journaled in a bracket 36. Shaft 35 carries also a bevel gear 37, in mesh with a bevel gear 38 at the end of a shaft :39 carrying at its opposite end another bevel gear in mesh with a bevel gear 40 on a shaft 41 equipped with a hand wheel 42.

The shaft 39 of gear 38 carries also a bevel gear 43 in mesh with a bevel gear 44: on they shaft 45,'the motor 46 is provided on a bracket 47 attached to the front end of the body 10 and said motor drives a propeller 48 and can be controlled from the cabin.

The operation of my device will be entirely clear from the above description and by simultaneous inspection of the drawings. The aeroplane is started in the usual manner by the operation of propeller 48. The steering is done in the customary well known manner, but the side steeringon either side, for left side left steering, for the right sidev the right steering (16).

It will be clear that in emergency cases the pontoon will keep the craft afloat and the sails in this case when properly set will allow a propulsion of the craft in case of motor. defects.

It will be understood that I have described and shown the preferred form of my invention only and that Imay make such changes in" its construction as come within the scope of the appended claims withoutdeparture ,from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An aeroplane comprising a body, means for propelling said body, steering means, danding gears, a pair of wings, adapted to 'act as sails, means for setting the same, and w a triangularly shaped pontoon to float the craft on water.

2. An aeroplane comprising a body including a cabin, stabilizing means connected therewith, steering and landing gears, a pair of wings of substantially triangular shape,

rods to'which said wings are secured at their inner meetiri'g edges, and means to operate said rods z'lor'tilting up said wings, and set the same for acting as sails.

3. An aeroplane comprising a body, a front landing wheel, a pair of rear landing wheels, a triangular pontoon member carrying said rear landing Wheels attached to the body, horizontal and elevation rudders, a propeller,

tilting wings, and means for operating said wings.

4. An aeroplane of the class described comprising a. cabin body, a pair of substantially triangular wings rods to which the inner 39 meeting edges 0 said wings are attached,

arings for said rods, the rear ends of said rods curved and straight, a train of bevel gearsfor allowing a tilting of said wings, and means on front end of said wings to move the tilted up sail wings to the left or ri ht.

5. In an aeroplane of the clas'sdescrib a pair of wings, means to which said wings are connected to allow a. tilting up of the same, a member to which said means are pivotally 40 connected, a transverse threaded rod carrying said member, and provided with a hand wheel, for allowing a lateral displacement of the wings, with respect to the body of the aeroplane.

6. In an aeroplane of the class described, a pair of win rods carrying the inner side edges of sai wings, bearings for said rods, a train of gears connected with said rods, means 7 for allowing a lateral displacement of said rods and wings, and a means for setting said wings.

In witness whereof I have signed my name to this specification.

EMIL JUST.
