' AERQPLANE.

To all whom it may concern:

' e it known that I, VICTOR H. LATnNDonr, having declared my intention of becoming a citizen of the United-States, and resident'of Bayonne, county of Hudson and State of New Jersey, have-invented certain new and useful Improvements .in- Aeroplanes, of which the following is a specification. This invention relates to airships, and more particularly to the type of heavier? than-air machines usually called. aeroplanes. ,The improvements constituting the inven tion are particularly, though by no means exclusively, adaptedto the mono-plane form of aeroplane. i

The object of the invention is to produce an aeroplane presenting wings which will closely reproduce the qualities of the wings of soaring birds, with-a view, to securing the best results in the way of sustaining power and stability.

To these ends, the invention consists in the matter described andin the claims. more I he accompanying drawings illustrate what is believed. tube the best form of the invention; but it should be understood that many, apparently different, embodiments of the invention may be constructed without dcpartingfrom the scope thereof.

In these views, wherein similar characters of reference indicate similar parts in all side elevation of I Specificationof Letters Patent. Application filed April 5, 1910. Serial No. 553,523.

taken on. the line 2-2 of'Fig. 1'; Fig. 3 is a der and the stabilizing surfaces in midposition: F 1g. 4 1s a plan view, showing the rudder moved to one side and the stabil- 1 between thev frame members lzing surface at thatsiue projected; Fig. 5 isa detail elevation on an enlarged scale of I the parts for supporting and actuating the one of the stabilizing. shown in vertical cross-seclongitudinal sectional elevation of the parts at the forward part of the" aeroplane; Fig. 7 is a'perspectivefview of lowering planes and immeparts; and Figs. 8 and!) right angles showing one of the frame" members;

In these views, the numeral 10 indicates a" supporting plane, consisting of two wings ll and '12. These wings extend outward and slightlyupward from a longitudinal median line, which median line, in the best form of the invention, dips gradually to the rear, as clearly shown in Fig. 1. These w ngs will usually be made of canvas or other flexible material stretched between frame members, the preferred arrangement of which willnow be described. A central longitudinal frame member 13, which defines the median line referred to, extends from front to rear of the plane and is slightly arched. In accordance with the invention it is arranged so that from a point in rear of its front end, but materially nearer said front endthan its rear end, it is dishmvn in Fig. 4. Side frame. members 15 PatentedJuly30,1912.; i

dlverge rearward from the front end of the;

central frame member13; the front ends of. being suitably these three frame members united together in any usual or approved manner. In accordance with the best em bodiment of the invention, these side frame members 15 are bowed or curved slightly, in an outward and upward direction, that is, their curves lie in inclined planes. The rear ends of the side frame members 15 are con nected with the rear end of the central frame member l2b'y rear frame members 16, which converge rearward.-' These members 16 are straight-in the, best form of the invention. 1 The angle between these rear frame members 16 .is materially greater than stretching the canvas or similar material as described, andfparticularly when the aeroplane is in motion, with the canvas somewhat bellied upward under the air pressure, they closely correspond in action tothe wings of soaring birds..- The side members nected with the central frame member 13 by straight brace-members'17.

A propeller 18 may be mounted on the plane 10' at either end thereof, or may be supportedor mounted'in anysuitable or apby a motor 19, which I is supported on a platform 20 for the operator.

When the rudder is swung to one side or other, tendency of the plane to tip to that side isneutralized by the transverse shifting of the stabilizer.- The aeroplane I may rest upon the ground upon wheels 46, for the purpose of securing a running start. Having thus described my invention, what I claim as new, anddesire ters Patent, is: a

As shown, this rudder has its yertical rudder surface disposed over the rear part of the plane 10, and is connected pivotally with the mast 21 by long supporting rods 24:.

This frame may comrise three parallel rods, a rod 37 which is journaled in the 'bracket 36, and top and bottomrods 38, to which may be secured operating ropes or the like 43, which extend to an operating wheel on the platform. Theends of the.rods-.37 and 38 maybe con.- nected by brace rods 40, and b ace rods or ropes 41' may connect the ends 0. these rods 40 with the front and rear edges of the planes 34-. In passing downward to the operating wheel 39, the ropes 43 may pass over widely varied. As shown, it comprises two stabilizing surfaces 28, 28, which are connected by a rope wire, or other means, 29 to move together. These stabilizing surfaces may, however, be distinct. These surfaces 28 are shown as mounted to slide transversely beneath the plane 10 in a suitable member and dis osed at a slightly greater elevation, rear rame members connecting the rear ends of'said central-"and side frame members, and material supported by said frame members and constituting wing surfaces.

4. In an aeroplane, a supporting lane comprising a central longitudinal rame member which, from a point in rear of its front end but materially nearer its front than its rear end, extends gradually downward and curving to the rear, diverging side the aeroplane, by reason of longitudinal junctlon and thence extended outward and slightly upward to diverging rear, diverging side 45 are shown connecting the several angles .A guy'- to secure by Letcurving from the front of said central frame side frame members, and material stretched between said frame members and constitutlng Wing surfaces which extend outward and.
