12 Claims.

This invention relates generally to improvements in ilying'devices and pertains particularly to a model or toy type o f such device which is designed for direct vertical ascent and descent.`

A primary object of the present invention is to provide an improved flying device which is designedv to rise or descend vertically by the provision of wing sections which are mounted upon or connected with the fuselage of the plane to rotate above the fuselage, thereby substantially functioning as an air screw, the said Wing sections being caused to move through theair by propeller units rotatably mounted thereon and driven from a sourceof power which turns with the Wings and which isl supported on the axis of rotation thereof, so that a balanced condition will be maintained and the effects of centrifugal force will be reduced to a, minimum.

Another object of the invention .is to provide a vertically ascending or descending flying device propelled in the manner above stated wherein the wing sections by which the ascent and descent of the device is eected are oscillatable on axes perpendicular to the axis of rotation to facilitate the adjustment of such wing sections to any desired angle of attack within a prescribed range.

A further object of the invention is to provide a flying device ofthe character stated wherein the axis of oscillation for the wing sections is at an oblique angle to the length of the sections thereby facilitating the adjustment of the angle of attack and at the same time facilitating the transmission of power to air screws rotatably mounted upon the leading edges of the sections.

A still further object oi' the invention is to provide in a flying device of the character stated. a coupling between the pivotally or oscillatably mounted wing sections which produces an equalization of adjustment of the sections through torque strain applied to the sections upon the operation of and by the power mechanism by which rotary motion is transmitted to the air screws mounted upon the leading edges of the ving sections.

The invention will be best understood from Aa consideration of the following detailed descrip-A tion taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the inventionis not to be confined to any strict conformity with the showing of the `drawings but may be changed or modified so long as such changes or modifications mark no material departure from Fig. 2 is a view in side elevation of'th'e same'- showing the rotatable wing sections in fore and aft position.

Fig. 6 is a view on an enlarged scale partly in top plan and partly in horizontal section of the power transmitting coupling between the prime mover and an air screw.

Fig. 7 isa sectional view on the line 'l-l of Fig. 4.

Fig. 8 is a sectional view on the line 8-8 of Fig. 2.

Referring now more particularly to the drawings, the numeral I generally designates a fuselage structure of a conventional design, such structure being equipped with an air screw 2 at its forward end to facilitate horizontal or forward flight movement oi' the structure and with vertical and horizontal rudders 3 and 4 for con- No details of construction of the fuselage are shown as. this forms no part of the present in vention. Any suitable fuselage or body structure 5. vmay be made use of so long as the same is equipped at its center of gravity With a vertical post or. mast 5 upon the upper end of which the wing structure is mounted.

In accordance with the present invention there is provided upon the upper end of the mast 5, a step bearing 6 in which is supported for rotation the vertical axle l. Fixed to the Iupper end of this axle 1 are the two opposite and radially directed sockets 8, each of which at its outer end is provided with the oppositely disposed notches 9 which are in a vertical plane, as shown in Fig. 7.

The wing structure for the present ying device ls made up of two wing bodies, each of which is indicated generally by the numeral I0. Each of these wing bodies or members is of elongated form having the front and rear longitudinally spectively, which are joined together by the inner and outer bars 'I3 and I4, respectively. Crossy arms or braces l! connect the front and rear bars of the wing frame and the frame is covered by a suitable covering material or fabric I6.

` Each wing body or member is shaped so that the front and rear bars or edges, while substantially equidistantly spaced throughout their lengths, are angularly related, thus giving to the wing a slight twist on its long axis with the result that when the wing members are `set for the ascent ofthe device, as shown in Figs. 1 and 2, the outer portions of the wings will be substantially horizontal while the inner portions will have the leading edge at an elevation above the trailing edge. When the wing members are set for descent of the device, as hereinafter described, then the inner end portions of the members will be substantially in a horizontal plane and the outer end portions will be at an angle to the horizontal, the leading edge at the outer end portion being at a lower elevation than the trailing edge.

Secured to the frame oi each wing member is a spar I1 which extends obliquely of the wing from adjacent the longitudinal center at the inner end thereof toward the leading edge of the wing. The outer end of each spar is braced to the outer cross bar il of the wing by the oblique brace bar I 8.

'I'he inner end of each spar I1 extends beyond the inner end of the wing member to which it is attached forming the supporting foot i3 which is designed to position in a socket 8. By this means the wing members arev coupled with the rotating vertical axle 1 supported upon ,the mast 5.

Disposed beneath the sockets 8 and extending substantially parallel therewith is an equalizing bar 20 which is freely pivcted on the axle 1 substantially midway of its ends and at each outer end of this bar, a. slot 2l is formed.

The foot portion I3 of each spar carries a transversely extending pin 22 which, when the foot is placed in the socket, engages in the slot 2i in the adjacent end of the equalizing bar 20. 'I'he notches 9 in the ends of the sockets 3 are of sufficient Width to receive the pins 2| and to permit limited turning movement of the foot in the socket, but the pins are relatively tightly held in the slots 2| of the equalizing bar and thus it will be apparent that when a wing member I is oscillated, the pin 22 connected therewith will swing in a manner to cause the equalizing bar 20 to turn slightly on the axle 1, and this turning movement will impart corresponding swinging of the opposite pin 22 and a corresponding oscillation oi the other wing member. Consequently the wing members will always be maintained in the same relativek angular disposition and when the angle oi' one wing member alters, it will automatically alter `the angle of the other member.

Adjacent each of the slots 2i of the equalizing bar, there is ilxed to the equalizing bar a latch'- ing ilnger 23, which has a hook 2l adapted to engage across the adjacent pin 22 for the purpose of holding the pin and the wing member with which it is connected from shifting outwardly or lengthwise of the adjacent socket.

thereto of a contractile strand 25' which normally functions to urge the wings to oscillate to the descending position. Obviously when the plane is in motion and the wings are being 'rotated under the action of the air screws 23, the twist or torque action imparted to the wings along the lines of oscillation therefor will cause the wings to oscillate to the ascending position. Obviously the strand 25' will not be of such strength as to prevent the torque action of the twisted rubber stand 35 from oscillating the wingsto such 'ascending position.

Adjacent to or slightly outwardly from the transverse center of each wing member, there, is. mounted upon the ktop of the wing, a. base or bracket plate 26 supporting the bearing 21 in which-is mounted a shaft 23. Upon the forward end of the shaft 23 there is mounted the air screw 29 which is set forwardly of the leading edge of the adjacent wing member to' rotate on an axis'extending transversely of the member. Inwardly of each air screw shaft 23 there is supported upon the bracket 26, a rotary power transmitting unit which is -indicated generally by the numeral 30 and which4 is here illustrated as consisting of a number of. bearing posts 3|, throughl each of which extends the rotatably supported stub shaft 32, each end of which is vformed to provide an eye 33 which constitutes one element of a universal coupling. Between the stub shafts the adjacent eyes 33 are connected by a link 34, which forms the other element of the universal coupling and the shaft 28 is connected with the eye of the stub shaft 32 nearest thereto, as is clearly shown in Fig. 6.

As has previously been stated, a principal object of the present' invention is to provide a rotatable wing structure in which the driving means for the air screws and for the wing sections or the prime mover, is mounted together with the other parts in such manner that the weight of the parts will be distributed so as to prevent undesired strains being developed as a result of centrifugal action or, in other words, the weight of the parts is equalized and the power means or prime mover is mounted to turn with the air screws and the Wing members and to be disposed above the latter so that all of the weight will be distributed above the wings and evenly with respect thereto.

As a means for eilecting the turning of the air screws 23 and the rotation of the wing members on the center of the axle 1, there has here been illustrated a rubber strand, which is indicated generally by the numeral 35. This strand has connected with each of its ends, a' hook 38 which is designed tov be engaged through an eye 33 of the innermost one of the stub shafts 32. This strand extends obliquely across the two wing members or the wing structure and extends over the upper end of the axle 1, being above and parallel with the alined spars I1 of the two wing members. The sockets at their joined ends support a guide ring 31 and. this is alined with other guide rings 33 which are supported upon the spars of the wing members. These guide rings have the resilient or-rubber strand 3l extended therethrough and they function to pre-A vent the strand, when it has been twisted so as to build up the necessary power to effect the rotation of the air screws with which \it is connected, from lmposingn upward pull upon the wing members which Vwould place undesired strains upon the same.

The twisted rubber .strand Il will function effectively to turn the air screws 29 at a suitable speed to cause them to pull the wing members around' on the axle 1 so as to thereby lift the craft into the air vertically.v When this is occurring, the torque strain which will be applied to the spars and consequently to the wing members will tend to raise the advancing edges Il of the wing members and since the wing members are coupled together by the equalizing bar 2G, the degree of pitch which the wing members will assume will be the same. Fig. 5 shows the appearance of one wing member when looking lengthwise thereof from adjacent the rotary center of the wing structure, when the wing member is pitched for ascent. In this View it will be seen that the leading edge i I at lthe inner end is raised while the trailing edge I2 is depressed and the outer end portion of the wing member is substantially'horizontal. The dotted outline D of this ligure illustrates the position of the wing member when it has been shifted to the descent position where it will be noted that the inner transverse edge or bar I3 is substantially horizontal and consequently the inner end portion of theA wing member is horizontal while the outer end portion is on a slope, the leading edge Il being depressed-while the trailing edge I2 is raised. This shift in the positions of the wing members may be brought about by a yieldable or a contracting connection between the arms 25, which are connected with the equalizing pins 22 or it will occur in the following'manner. When the craft is ascending, the torque exerted upon the Wing members by the tensioned and untwisting or turning rubber strand keeps the advancing edges ofthe wing members elevated as previously stated. However, when this torque strain relaxesor ceases to exist, the pressure of the air against the under face of each wing member adjacent the trailing edge and adjacent the inner ends of the members will tend to force the trailing erige of each wing member upwardlyso as to dispose the inner endsof the wing members in the same horizontal plane. As a result, the outerV end portions of the wing members will turn so that the leading edges Il will be depressed to an elevation below the trailing edges l2. When this occurs, the wing members which previously had functioned as a screw to raise the aircraft, will now function as a screw to move' the. aircraft downwardly or allow it to descend. While there has been here illustrated a prime mover or power unit in the form of a twisted rubber strand, it is to be understood that the invention is not to be limited to .the

use of this specific form of power developing means Yas it is possible to employ other forms of prime movers supported to turn-with the wing members upon the axis of rotation therefor and, therefore, it is to be understood that in' the appended claims, the use of theterm power generating means o r prime mover is intended-to cover any and all suitable types of mechanisms for operating the air screws.

A particularly important feature of the invention is the provision of power delivering means for the propellers which results in the propellers being differentially driven. 'This will be apparent Y when it is considered that lthe -twisted rubber strand will naturally deliver the most power to the propeller oering the least resistance. This helps to equalize the power on the air screws at While in the illustration and description ofthe invention the prime mover for the air screws, here shown as being in the -form of a'twisted rubber strand 35, has been shown and described as lying above the wings, it is to be understood that the invention is not to be limited in respect to this location of the air screw driving means as it is contemplated to place the prime mover or driving means for the air screws beneath thewings or in the case where wings of the airfoil type may be employed, the strand may extend through the wings or, in other words, may lie between the top and bottom surfaces thereof. In the placement of the strand 35 beneath the wings, it will, of course, be understood that the stabilizing bar 20 willl be disposed above the sockets for the ends of- ,with a ring or an eye through which the strand may pass. In other words, the parts as now illus- 'trated would be merely reversed so thatv the strand 35, the air screws and the driving connection between the ends of the strand-and theA air screws will be disposed upon the underside of the wing sections instead of upon the top thereof.

It is also to be understood that whereas the'de- .vice as herein illustrated obviously constitutesmerely a toy or a model of an aircraft, by the use of other types of prime moversvfor eecting the rotation of the air screws, thegstructure may be built of a size to be suitabley for commercial and other uses.
