15 It is well known thalfto sustain an aeropla-ne the upward pressure ol? the air upon lts planes moet; he equal .in li'oreey 'to the Weight of the machine. From this it will be readily appreciated that the, shape and curvature of the planes upon which the air pressure is directed is of utmost importar-lire and it is my aim to provide planes designed so as to :secure the utmost lifting; power with the minimum amount of air pressure.

In carrying out my invention, I provide a transverse plane7 which will be termed a ear rier, plane, haring' a eonenre upper surl'zmo, and guide planen seein-srl at their edgar; afl-- ja'eent the forward ends thereoh to the transverse pinnev said ,guide planes conrergiine' rear-wardly and being eo'nneetfnl to eaeh other at their rear extremitiee. rlhefse tfHf-l planes are ilonhly ein-ved7 hai/iin; their upper surfaces adjacent their forward ends concave, and adgaeent their rear ends con- Vex. This structure insnree` a steady pr sure 0i? air upon the under surfaces o'l the planes, 'in such n manner as to iu'ipart lo the forward ends thereof, a lifting loroe.

The invention also aime` to provide finit-- able means whereby the machine may he ensilj.Y controlled,

1With these and other objects in View as will become more :apparent ae the flowerintion proceeds, the .invention consists in eertnin novel features of combination, eonsl'ruation, and arrangement of parts`- which will be hereinafter fully described and claimed.

The hare l to which the forward ends ol `the guide planes 10 nrc secured, arey essentially` straight and inclined slightlyY upwardly from their inner ends. The frame bars 2 and .5 entend downwardly and forwardly from their extremities in regular curves and have secured between them, the carrier plane ll. The ends of this plane are attached to the frame bars 6. The Guide planes 10 are attached, as is clearly shown in Fig. l, to the frame bars 1, 3 and 7, said last mentioned bar being essentially straight and inclinedv downwardly and rearwardly. lt will be apparent that an upward air pressure on the carrier plane 1l, will tend to support the aeroplane and the same pressure acting upon the guide planes l() will give to the machine a forward motion. The manner in which the guide lanes converge rearwardly also increases the tendency of the machine to a forwardmotion when acted upon by a lifting air pressure.

A car frame is supported by the frame bars 2 and 5. The car frame comprises top parallel bars 12, front downwardly converging bars 13, an angular centrally positioned bottom bar 14, and rearwardly converging end bars 15. rlhe top bars 12 are connecte to the frame bars 2 and 5, by means of suitable straps 16 and the various bars forming the car frame are connected by couplings,

as clearly shown in Fig. 4. If desired, preferably canvas strips 17 may be employed to form the walls ofthe car. A11 engine 18 is suitably secured within the car and drives the shaft 19 to which is secured the fly-wheel 2O and pulleys 2l. Belts 22 are employed to drive the propeller shafts 23, through the medium of the pulleys 24, which are rigidly secured upon sald shafts. The shafts 23 are secured to the bars 12, by means of the hangers 25, said hangers being formed upon sleeve members 26, which are secured in position by set screws 27. The aeroplane may bel guided and vertically supported by the rudders 28 and 29, which comprise preferably canvasv strips secured within suitable frames. A central rod 30 extends longitudinally of each of the rudders through a suitable bearing 32. Steering rods 33 are connected to the cranks 32 and to suitable levers 34. These levers are positioned adjacent a seat 35 and are pivotally connected at their lower ends to a bar 36, said bal being provided with two pairs of spaced ears 37. It will he seen that this construe tion perniits the operator to readily shift the rudders either simultaneously or individually, so as to direct the machine as desired. l

Supporting wheels 38 are journaled. within the lower ends of standards 39.

' It is to be understood that l do not wish to be confined tothe exact curvature of the sideplanes herein described, but may change them as well as the carrier plane, provided the changes fall within the spirit and scope of the invention.
