SUPPORTING DEVICE FOR AVIATION.

S'pecification of lletters Patent. Patel lied une 13,1911- Application filed-June 4, 1910. Serial No. 565,111.

Toall wlwm it may engineer, a: citizen of the Republieof r y g France, resident-of Marseille, Bouches-du- Rhone, France, have invented new and useful Improvements in Supporting Devices for Aviation, which improvements are fully set forth in the following specification.

The present invention relates to an improved supportingdevice for aeroplanes and which constitutes a reotangularplane one relatively to the other, two bends or rolls of variable size and conical inv form arranged above the supporting plane. a

The object. of the invention is to provide an aeroplane or like apparatus with improved means for obtaining perfect stability for facilitating steering and for preventing falls;

The device asawholc is intended tocarry goods or passengers-in theair for traversing the ground, water-courses, lakes, seas, etc. or for scientific war-like or other apparatus with or' without passengers, or experiments or for'toys of similar form and of larger or 7 smaller size constructed of any appropriate material.

The subject matter of the present invention is illustrated byway of-example in the accompanying drawing, in whidli:-

r thejsupporting or stabilizin cones. Fig. 3.

- Figure 1 1s a plan viewof the supporting device; Fig. 2 is a side elevation of one of is an elevation of the rear 0 the supporting plane.

' straight or slightly concave.

-' The supporting plane is constructed of light material of any suitable kind provided it is ofsufiicient strength.

The improved device consists of a supporting plane 1 of rectangular form .and of any sultable size according to the load to be arranged at the front end of the supporting 'olaneand their base at the rear end of-this 1 same plane. Be it known that/I, GEoBons' BARB-sum,

at its ends and arranged inversely They may T to; supporting, plane, or they mayconstitute a contlnuatlon thereof according some method of manufacture employed. The

front part4- of the supporting i planef l hi sl ghtly ralsed viz., to the extent-ofaabout 1/30 to 1/20 of its widthfaccordihgitp the angle of attack of the air to be obtained, for

efliclentoperation of the aeroplane. 1

.It will be readily understood from the following remarks that the. cones 2 andfB act upon the air as safety means 'fonmaintaining the equilibrium of'the supporting plane 1 in its normal position in caseof 'ac- 7o cident or impossibility ofjsteeri it..

It is to be observed that the outer walls 1" of a cone when arra'ngedat one of the ends of the wings of a supporting plane, en-

counter the more or less regularly. arranged 76 or normal particlesof theatmosphere and the pressure of these particles toward the 7 rear becomes increasingly vigorous in proportion as the speed of the apparatus is augmented. The forceof suchaction owing, to 80 the construction is transmitted almost .entirely toward the rearfof the supporting plane. The rear part of the" supporting .plane being thus maintainedin its horizontal line of flight relatively to the front part 8 it becomes obvious that the front part will. have a tendency to rise. If the rear part which is retained by the conical arrangement horizontal relatively to the front .part

of the plane, should-rise, the latter would in this case become directed much 'more speedily toward the ground in as much as the apparatus loses a part of the support ofv the plane, and as theweight of the appliances and motors are located in such a man ner as to increase the velocity of the fall. which becomes inevitable unless something immediately comes into action to stop this fall. It is such a fall that I propose to prevent by causing the front part f th paratus to rise in all cases. By means of the arrangement of the more or less closed cones this function is performed and without the intervention of any mechanism whatever that might possibly be out of order when necessary for preventing-a fall.

Taking into account that the resistance to forward displacement plays a large part in I the art of aviationit will be understood-that. 1 I if one of my improved conical devices were no fitted on the left hand side the apparatus u would constantly turn toward the right; "on

the other hand, if one of such cones were fitted on the right hand side the apparatus would constantly turn toward the left. Therefore in these conditions if the two cones are similar, the apparatus carried along by its head-in forward weight would proceed straight ahead. Consequently, ifwhen traveling at full speed the relative sizes of the cones are varied, the aeroplane will turn to one side or the other, according to the maneuvers, taking for its pivot or turning base the cone-whose surface presents the greatest resistance in the air, the other side traveling quicker owing to this. This changing or varying of the size of the cones to the right and left can be performed in various ways. By their action at the end of the supporting planes these cones serve to impart stability and to effectively prevent falls.

The changes of direction in elevation, steering to the right, steering to the left, restarting forward, running or any adjustment of the aeroplane may be obtained by the means heretofore employed for ,aero planes or similar apparatus. Changes in direction may, however, be obtained in this type of aeroplane by enlarging or reducing the dimensions of the cones 2 and 3 by any suitable means. Left hand turns are made by opening out the right cone and right hand turns by opening out the left hand cone, by reversing the gear used for this purpose.

' Forward travel in a straight line is effected by bringing the right or left hand cone (according to the maneuver that has just been effected) back into its normal position in such a manner as not to steer the eeaeee aeroplane either to the right or to the left, L

merely allowmgthe two cones to serve their purpose as safety cones.

T he phenomenon arising during the turning will be readily understo od. The cone at the extremity of the wing which is depressed as a result of the turn forms a point of support for the apparatus as a whole, while the cone which is situated in the turn at the upper end of the wing which arises, acts as a suspension hook.

Propulsion maybe effected by any known means.

' Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. An apparatus of the character described,"

comprising a plane having a substantially conical surface at each end, one side of each of said conical surfaces being a continuation of the surface of the plane.

An apparatus of the character described, comprising a plane ha ing upon its upper part, at each end, a flexible substantially conical surface.

3. An apparatus of the character described, comprising a, plane, said plane having tlcxible ends which are curved upwardly and inwardly of the plane to form incomplete 'conical surfaces.

In testimony whereof I have signed this spec1ficat1on 1n the presence of two subscrib- 111g Witnesses.
