illinois.. have far. remise, and exheing had to the ing a part of or the type @ne ot the objects of Y roride ari improved 'lich i'nay oe readily Conno' only as to lateral bnl-ence but as att balance. aown for the purpose of di5elosing inj.' invention one f nhmlinient thereof in thev aeronimnying drawings. in whiche l is a top plan view of iny inven- :2 is a small -view showing a plan of tl e liottoni plane ot' iny invention; Fig. 3 is a de levni'ion: t is a front elemtion; Fig. i3 is a side. view ot the propeller used in Connection with my {lying machine; and, Fir'. f3 is a front View of the propeller.

'i'he structure shown i ie drawings coinri.I :1 framework, orei which is stretched i upper plane 2 and a lower plane 3. This BO ai trameworli preferably comprises the upper lateral spare l and 5, which are spaced apart at their ends' .by tore and att struts G and 7 d are connected to siinilarliottom lateral y i d tor connecting the .i ,ars together. Connected to ng longitudinally of the lateral upper longitudinal sparsi lO which are epaced apart at their forr ends hy lait ral sparers l2 and mineeted to similar bottom spars posts i5. The Yframework the shape in plan, in efellelograing one extendotlier overlapping the and extending' transi' the struts 3 and 7, n.. of the machine, are 5C t s i6 and l?, which are Letters Patent.

toot lever 22 mounted in drivers seat 23.

The upper plane may be termed of any Suitable fabric. such as Canvas or other material. and takes the general shape of a. triangle havingr its hase projected slightly and provided with a. bea 24. The extreme lateral ends: ot the plane are connected 'to the ends ot the hell eranlr levers 16 and l?. The edge of the plane is Connected, as et 25 and 26, to the rear upper spar t ofthe traineworl and the rear end of the canvas is Connected, at 2?, 'to the spacer l2. The front of the small heal' 24 is connected to the end of the bell Granit lever :20, while the side portions or inner ends of the beek are eenneeted at 27a. to the front spacer 18. lt will thus be seen that the lateral edges or ends oit the top plane form a pair of movable tips and the iront beak 2l likewise forms e movable heal; or tip in front ot the machine. By operating the lever 19 one of the inevahle side tips may be depreseed and at the same time the opposite tip will be elevated. Also, by operating the toot lever 22 the front beak or tip 2l may be depressed or raised.

Extending rearwardly from the treme# worlr above described is a. framework oomprising4 the upper and lower side Spzirs 28 and 25) and the top and bottoni spacer bars 30. The inner ends of the side spare are secured to the rear Yertieal posts l5 and vertieel posts 3l extend between the rear ends o the upper and lower side Spare 28 and 29. rihis tan tail freine is covered on all sides except its front end hack by e. suitabley ineproximity to the .teriah which ma. be the same as the top planej and in e eet forms a fan tail '00X open at front'and back. lt will thus he Seen that in top plan the upper plane, including the tan-tail box, resembles very closely `the shape of a bird with its wings outspread.

The bottom plane, which may be formed of the saine materiales the top plane, conforms to the outline of the framework and has its front edge slightly roundedv @if and .stitl'ened, as at. 39.

irrrangeo in the front portion of the fair tail box. on each side7 is a pair of vertically arranged, rearwardly extending;7 angniarly lisposed planes 33, which are stationarily mounted, and pivoted between the lop and bottom spacers l2 is a pair of vertically arranged movable planes 234 which may be moved so that their rear edges engage the -rear edges of the planes 33 and thereby completely close"the b'ox,.,or which may be adjusted in such position that a wide space is lett between the planes 33. 'These planes 34 are provided with 'a pair of lintermeshing 4segmental Agears 34C, so that the two planes `wili operate .1n synchronism, although 'in mechanism 38 connected with an operating handle 39.

Extending between the vvertical struts connecting. the rear upper and lower lateral spars ista propeller shaft 40 on which are mounted propellens l2 and 4:1. These pr0 pellers are of peculiar Aform and are preferably constructedA in the formlof tapering lhelices, such as illustrated in Figs. 5 and 6,

having their edges beveled as at 42, which.

edgesl during the rotation of the propellers l tend to -force the machine forward. Ex-

tending transversely of the langer portion of the helices is a vertical blade 43 which also aids in propelling ,the machine forward.

'The shaft 4() is driven from a suitable engine 44 by means of: gear mechanism A5.'

While I have shown and described the preferred embodiment of'my invention in the accompanying drawings and specifica- A' tion, it will be understood that various modifications and changes may -be made therein without departing from the spirit of my invention as set fort-h inthe accompanying drawingsf Having l. ln `a flying machine, the combination with a lower plane having lateral rectangular wings, ya rearwardly extending rectangu-` lar tail-piece and a fan-shaped extension of said tailfpiece, and an upper plane substantially triangular in shape. having. a fan` tail extension from the apex of the triangle u and a triangular beak extending drwardly from the basorof the triangle.

2. A vflyiriglmachineV comprising` a lower plane having transverseV rectangular wings,

arearward rectangular extension from said vwing'. an upper plane substantial] trianvular at its front and back connected'atthe apex of vthe upper plane and to the rear of the rearward extension ofthellower plane. m18. In a flying machine, the combination .with an upper and lower frame forming a transversely extending parallelogram anda rearwardly extending parallelo ram, a dCovl ering for the bottomv frame, co orming substantially to the vshape there0f,-and a suit-e.

able cover extending over the top frame, .sub-

stantiallytriangular in Shapeand having,

its ends projecting beyond the sides of the frame and having a triangular beak extending beyond the front or the frame,4 and means for raising and lowering theends and it. Ina flying machine, the combination witn a lowerplane havin lateral rectangu-A lar wings and a rearwar ly-extending tail piece, a top plane substantially triangular in shape, a box fan-tail open at its front and rear connected to the rear-of said plane, and

in shape, and a box fan-tail open means for controlling thesizeoi the opening 1n said box. A I

5.'ln' a iying machine, the combination with av lower plane having lateral rectangular Wings and a rearwardly extending tail piece, an upper plane substantially triangular in shape and a box fan-tail secured to the rear of said plane, angularly disposed planes arranged between the top and bottom of said? lbox, fan-tail, a pair ot planes pivoted at;

. their center and so arranged that theirrear' edges will respectively engage the ed es of Y, said ldiagnallyfv4 `arranged planes an l -jt-he thus described my invention,I what I claim as new anddesire to secure by'.
