the former the present invention is charac-A terized by a single spar or Outriggerl rearwardly extending from the hull at or near its amidships section, to the empennage. This spar reinforces and strengthens the tail structure of the hull, which is comparatively light, takes up the inertia of the empennage in landing, and carries the major portion of the lift load of the tail unit or empennage under certain conditions of flight. The invention is further characterized by an im'- proved and somewhat different type of en-v gine mounting. Instead of the conventional V-support a substantial M-support is provided. The upwardly converging legs of the M-support are fastened to the respective engine bed'beams by suitable fittings common to the adjacent struts. This M-brace or support together with a forwardly and downwardly inclined post brace take up not only the inertia stress in landing but the thrust eifort of the power plant while the machine is in Bight. The power plant is of the single unit type and consists of a highpowered motor, afuel supply system (including lubricant tanks) a radiator and propeller. The radiator is mounted at the forward end of the engine-bed and the propeller (of the pusher type) at the opposite end thereof. The general arrangement of the various elements of the power plant and Ithe relative location of these elements with respect to the supporting surfaces and en' gine bed constitute further features of novelty which will be hereinafter more fully explained. v

spar, during flight of the aeroplane, not only braces the tail unit but, as before intimated,
takes up the entire inertia stress set up by rudder as well is increased'and the desired lift of the fin 23 assured.
Between the supporting surfaces. 15 and 16 and in the longitudinal vertical plane of the fore and aft axis of the craft the motor 17 is located. It is supported in place by engine vbed beams 26 arranged in parallelism. The engine bed beams arein turn supported by substantially M-braces or supports 27 founded uponthe respective wing beams of the lower wing.' The forward M-brace is inclined slightly rearwardly from the vertical plane to engage the beams 26 at points directly beneath the forward end'of the The M-brace 27 is more nearly vertical and likewise engages the` motor crank ca se.
beams 26 at points near the rear end of the motor crank case. The center legs of the M-braces and the outer legs of the M-braces are brazed or welded together at their upper ends to fittings 28 of substantially U-form which embrace the respective wing beams at the points mentioned. In other words, .one socket is provided for two legs of each brace. In addition to the forward M-brace 27 which takes up some slight portion ofthe Linertia stress of the motor mass and the thrust effort of the propeller there is provided a` forward diagonal post brace 29. At. its forward lower end it is carried into the fore body of the hull and anchored by any suitable means to the hull bottom. At its rear upper end it is equipped witha Y-fitting 30, the diverging legs of which extend tothe respective engine bed beams where they are fastened as at'31 at points slightly removed from the points of attachment of the forward M-brace 27. A suitable socket 32 is provided for attaching the post brace 29 to the Y. The function of the post brace' is to carry the thrust effort of the propeller and the 'inertia stress of the motor mass into the fore body of the hull where it is distributed over the hydroplaning area of the hull bottom.
Inverted V-braces or struts 33 interconnect the engined bed beams with the upper supporting surface 15. They are suitably spaced fore and aft to accommodate the motor 17, and inthe embodiment disclosed are sli htly out of vertical alinement with ,the M- races 27. Both of them are slightly forwardly inclined from the engine bed for attachment with the wingbeams 34 Of the -twice the strength and may upper wing. By thus inclining them to be vertical they are caused to'take up -a small with the M-braces in order that the motor' ma be accommodated between them.
Xt the extreme forward end of the en-V gine bed a radiator bracket 35 is provided. Its construction issuch `that the beams 26 are cross-braced and the radiator supported above them rather than at a forward point. Lugs 36 formed upon the bracket overlap the respective engine bed beams and with that portion of the bracket arranged between theL beamsl they constitute a rigid beam connection and brace. designated as 37 is supported upon the bracket and its size is ,such that the cap 38 islet through the nose end of the upper supporting surface 'as illustrated in Figs. v3 and 4. It is` thus conveniently situated and partly inclosed within the confines of the upper wing.
A streamline gravity fuel feed tank 39 is mounted upon (the upper supporting surface 15 directly above the motor. It is 'of substantially streamline form except for its sump 40. The sump however is let into the upper supporting surfacel where it is removed from the line of air rush to minimize head resistance in flight.'v The depth of the sump is such that its connection 41 with the feed line (not shown) to the motor extends beneath the under surface of the ring.
In addition to the gravity fuel feed tank 39 smaller tanks 42 are provided. :These tanks contain lubricant and are disposed symmetrically at opposite sides of the. engine bed for attachment with its respective beams by straps 43 and brackets 44. The straps embrace vthe tanks 42 and the brackets contact the beams. The tanks 42 The radiator are also of substantially streamline form.
The provision of M-braces beneath the engine bed is desirable in view of the fact that the weight of the motor Amass is distributed over a wider area of the hull and at points best designed to` carry it. The diverging legs of the Mbraces engage'the respective wing beams of the lower wing at points in substantiall the vertical plane of the hull sides and t e converging legs at points substantially in the vertical plane of the fore and aft axis of the hull, z'. e., its
keel line which is strongest.'Y Their connec.
tion with the wing beams issuch that the vibrational strains of the motor will not tend to loosen or weaken them. In other words the M-braces support the single centrally located engine bed so that 1t is of support twice lao - versely thereof, an empennage, and a brace.
various changes and modifications may be made therein without departing from' the spirit or 'scope thereof, and I aim in the appended claims to cover all suchmodifications and changes.
vWhat is claimed is.;
l. Anv airplane comprising a-4 body, an aerial supporting surface arranged transfor the empennage extended at its forward end into the body at or near the point of intersection of the supporting surface.
2. An airplane comprising a body, an aerial supporting surface arranged transversely thereof, a beam incorporatedin the supporting surface and extended into the body, an empennage, and a brace for the empennage extended at its forward end into the body for connection with the beam.
3; An airplane comprising a body, superposed aerial4 supporting surfaces arranged transversely thereof, a beam incorporated in the lower supporting surface and extended through the body, an empennage, and a brace for the empennage extended at its forward end into the body for connection with the beam.
