Especially in aerial navigation for instance, the form and means of action of the propelling der 5 do not answer Very well to the requirement for stability and security, which is sought for.

The present invention has for its object a-device for obtaining in the, above mentioned transformations of work a better uti lization and, especially in the case of aerial navigation, to re to the device more powerful means 0 action, a greater stability and, consequently, a more extended sphere of action.

Propelling apparatus have already been devised in which the active elements come,

' during the working or active period, in the mum resisting required position-so as to ive the maximum useful efiect and, during tie inactive period, in the position which necessitates the ministress. But in the known de vices, these e ements are moved to their position under the controlled action of me chanical members.

In the present invention','it is the forces generated by the very movement of the machine, reaction of the fluids, under the influence of the s eed and centrifugal force which place t e elements in their most advantageous position either for supplying or generating work or for offering the m1n1- mum resistance to the movement. 7

The present type of a paratus is con structed according to the ollowing' consid- -.erations:- Say a surface A (Fig. 1) of de-- Aerial Navigation, of which the following.

termi-necl shape, 'forinstancea curved rectangle, sus ended by-two of its sides and at determine points of its width a a, can rotate freely about these oints which are connected by two rigid ro s a 11 a b to a fixed axisb b For simplifying the demonstration, the surface or plate is illustrated hereafter by its profile A, the axis of rotation a" a by the point-a, the fixed axis 6 12 by the point 5 and" the two rods a 5, a Why the line a b (Fig. 2) This plate bein exposed to a stream of'air of determine -intensity and direction illustrated by the arr0w c ,-1t will take in the space a certain setting so as to *make "with the direction of 0 a determined angle a. If instead of bein held fixed, it is on the contrary supposed t at the plate A is given a peculiar movement, for instance a continuous gyration about an axis 12 through the medium of therod a b and in the direction .of the arrow '9 (Fig. 3), it will take of'itself a setting corresponding to the mini- ,mum resistance to the reactions of the air produced by the eliect of the relative speeds of the air and of the plate and the result ant of which is illustrated by the arrow h and will tend to cause rotation of the plate about the axis b.

If the plate A is accompanied b an abutment d (Fig. 4') it will be stopped in its rotary motion about itssuspension axis a, at the moment when, under the eflect of the reactions of the air, its setting will have plate. Being no longer held, said plate will pivot about its suspension axis a and the same cycle will be produced at each revolution the plate will make about the axis of rotation b.

The thrust due to the resistance opposed by the air to the movement of the plate stopped by the abutment is, for a form of plate suitably chosen, sensibly at right angles to the plane of the abutment and nearly constant in intensity. This thrust is transmitted by the rod a b to the axis b which becomes the seat of a traction and it may be understood that the system of which it would constitute a part and to which it would be connected, can be impelled or moved in space by this traction. The plate A will act .in this case as a kind of wing, by

resting or pressing upon the air with variable incidences, for .producing during the active period of its displacement a traction directed in a direction determined by the position of the abutment andmoving about its axis of suspension during the inactive period to such a position that it opposes to the air only the minimum resistance, these two periods succeeding alternately one another and in a continuous manner. By arranging abont one and the same axis several plates having with a common movement about said axis and each provided with an adjustable abutment, a traction can be generatcd which is not only constant in direction but also in intensity and can be directed at will in a determined direction by the position of its abutment. Thisarrangement,,utilizing a propert of the action of the air upon movable sur aces, can serve for obtaining a propellin driving or air displacing apparatus. Barticularly, by mechanically putting into practice the cycle just described, it will be possible to'produce a propelling apparatus and Fig. 5 illustrates diagrammatically, by way of example, a means of realization of an apparatus comprising six plates B, B B B B, B symmetrically arranged about an axis projected at C and by means of which said lates can receive a common movement 0 rotation while being capable of rotating themselves about their axes of suspension KQK, K K K, K which are rigidly connected to the central axis G either by arms, or by a disk, rigidly mounted on said axis and which are not illustrated in the drawings. On the other hand, abutments I, 1 I 1, lb, 1* are arranged so as to be able to rotate also about axes K to K The abutments correspond to hearing members m, m m m m, m secured to the plates so as to be able to press upon the abutments which are connected by trnnnions at, W, 71- 725, n, n and arms 0, 0 0 0 0, 0 to central hub p. The latter rotates on a pivot q, fitted in one of the arms of member r having the shape of a crank and which can loosely rotate on the shaft 0 driving the plates in its movement of rotation. The second arm of the member 1' is provided with a pivot s on which is mounted an operating rod 25, through the medium of which it is possible to modify at will the position of the crank r and to hold it in a determined position without stopping the rotary movement of the axis C. This operation may be controlled by hand by the pilot of the apparatus either directly or through the medium (if any mechanical operating device, actuated by the motor which imparts the rotary movement to the apparatus, or also by an automatic steering device. In the example chosen and for simplifying the demonstration, the setting is given integrally and simultaneously to all the abutments together, but each abutment can be provided with an independent opcrating device, so as to be able to give to each of the plates a certain setting at a determined point of its travel, in view of applications for which this would be recognized necessary or advantageous. The apparatus described being at rest and the crank r placed and held so as to maintain the abutments I to I in the nearly horizontal position of Fig. 5, if a movement of rotation is imparted to the shaft C in the direction of the arrow u, the plates will take positions such as B, B B B B In the case considered, the speed of the relative displacement of the air and of the plates is directed according to the tangent to the circumference described in the space by a point of the latter. The plate B has freely set itself according to the angle which corresponds to its minimum resistance, as above set forth, under the influence of its speed, shape and weight, which may be supposed negligible relatively to the other forces to which it obeys. The plate B which obeys the same law has come little by little nearer to the abutment I with which it comes into contact at last when it occupies the position B From this moment its rotation about its axis of suspension ceases, but it continues to be driven by the shaft O and by reason of its setting, which now remains constantit makes with the direction of the speed of its move-.- ment about C an angle which goes on increasing. Consequently, from the moment the plate has come into contact with the abutment, the air opposes to it a resistance which increases very rapidly and causes a pressure the resultant of which is exerted upon its axes of suspension and which remains sensibly constant and perpendicular to the direction of the abutment. that is to say, in the case under consideration, nearly vertical. This state of things lasts until the direction of the speed of the plate being then nearly horizontal, the pressure of the air will act upon its opposite face by causing it to rock about its suspension axis and by releasing it from its abutment. This will happen at the moment the plate will occupya position adjacent to B Said plate will pivot between the posit-ions B and B and will take again the setting corresponding to its least resistance, until, in the course of its movement about the shaft C and under the command of the forces acting upon it and to which it can freely obey, it will have moved toward the abutment and pressed on the same and where the. cycle described will recommence.

By a judicious choice of the shape of the plate, its center of gravity can be so placed that the resultant of the forces generated by the movements of the plates contributes: 1st to hold the plate pressed on its abutment during the active phase and 2d to release it from its abutment and to set it in its direction of least resistance during the inactive period.

The six plates B, B B B B, B ass successively inthese two situations a ter-- nately active and inactive, and there results therefrom a continuous traction which is transmitted to the shaft C by means of the rigid connection of the suspension axes of the plates with said shaft. In the particular case under consideration, this traction is directed vertically and upwardly. Its intensity depends on the speed and on the surface of the plates in action and it may be considered as directly proportional to these two factors.

The propelling device thus described being supposed placed on a system of supporting and steering planes, will take with it an ascensional movement through the effect of the vertical traction directed upwardly and determined by the resistance of the air on the plates in movement. If then, and without stopping the apparatus, the operating rod t s gaated upon and the crank 1" caused to rott'ltea bout the shaft 0 for bringing it in the positionillustrated in Fig. 6, the abutments I and I will take an inclined direction through the effect of the traction exerted upon the same through the medium of the arms 0 to 0 thus determining a new setting of the plates during the active phase and, consequently, a new direction of the thrust on their axes. The whole of the system can then take, under its action, a new direction in the space.

The apparatus which has just been described possesses the main following advantages:

lst.'The active member, the plate, is arranged in such a manner as to be capable of placing itself, during the period of work, in such a position as to always give the maxinnnnnseful client and to be capable, at the moment its eti'cct becomes null, of setting itself in the position which necessitates the 'work or operate in this case for slowin down the descent.

minimum resistin stress. The result is a very good utilization of the work.

2d. It permits iving at any moment to the force produce the most advantageous direction in view of the effect to'be obtained and without sacrificing the output.

3d. It possesses inherent stability which is the consequence of its conception and mode of operation by means of plates bearing or resting on the air. Considered as an aerial propelling device it will cooperate to produce general stability of any apparatus to which it will be adapted. By means of an adjusting device within reach of the pilot, it will-be able to produce at will its entire force for the vertical ascent, or for traveling diagonally under any angle, or for traveling horizontally; the setting of the plates can, in each particular case, be given for the obtention of the full output. It will always be possible to put in agreement the direction of the stress given by the propelling device with that given by the rudders of the apparatus, which will allow more rapid evolutions and greater security.

4th. By coupling two devices on one and the same apparatus and by animating them with speeds in reverse direction, it will be understood that, by setting their plates so that the thrusts which are exerted upon the same combat the effects of the gravity and of the wind and that the horizontal result- .ants be equal and of reverse direction, it is posslble to hover over a sp The very high useful effect of the plates of the propelling device will permit obtaining with a motive power even limited to the powers actually in use, an ascensional force sufficiently high for being able to rise vertically, either from the ground or from the surface of the water, and to consider the lifting or carrying of heavier weights and of imore powerful aerial machines than up to now. Also the landing can be effected vertically by a suitable setting of the plates of the propelling device which will be able to (Y If the apparatus is prd vided with two propelling devices capable if necessary of rotating in reverse direction, the pilot will have still more complete control than what has been stated above.

Figs. 7 to 9 illustrate the mechanical realization of an aerial propelling device based on the preceding principles. This propelling device comprises two series of six plates B placed on the right and left of the motor. These plates may be made either of wood or of sheet aluminium or any other suitable metal or alloy. They are securely attached to the enlarged parts of the pivots a. which can rotate freely in boxes I). The pivots are each provided with a cam shaped stop m which can press on the abutment I arranged inside the box. The boxes can thus rotate in rin s hub p through the medium of an device with its abutment-s c symmetrically mounted in the two plates D arranged at the right and lett side of the motor M on the shaft 0 to which they are keyed and which imparts to them its movement of rotation. Eachbox is rovided with a crank pin a through W ich they are maintained in an invariable setting, during their actuation by the .disks, by means of a member 0 having the shapeof a six branch star extending radially about the which constitutes an eccentric strap and can loosely rotate on the disk '1 the latter being also loosely mounted on the shaft C. 1

The disk r is provided with an operating stud e by means of which it will be possible, operating device (which is not illustrated), to vary the sets tin the boxes b and abutments all together Fig. 7 is an end view of thepropelling held horizontally.
