Specification of Letters Patent.

Patented sept. 19, 1911.

Application mea october e, 1909. Serial No. 521,189.

Be it known that we, PETER ZnMPoL and CHARLES ZAMPOL, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Aeroplanes, of which the followmg 1s a specilicatmn. i

Our mventionrelates to improvements 1n aeroplanes and it consists inthe combinations, constructions, and arrangements of parts herein described and claimed. An object of our invention is to provide supporting planes of such construction that they tend to maintain the equilibrium of the machine as la whole.,1

` .A furtherpbjectofour invention is to provide supporting planes and side planes so disposed toward each other that not only 20 is the equilibrium of the device maintained but each serves asa lifting or resistance element. Y

A further object of our invention is to provide means for protecting the ends of the supporting -planes in case 'the latter ated on one side 4of the center of t should dip downwardly and come in contact with an obstacle in vits path.

Further objects. and advantages will appear in the following specification and the 30 novel features of th device will be particu larly pointed out in Athe appended claims.

Our invention is illustrated in the accompanying drawings, in which- Figurey 1 is a plan view showing one em- 35 bodiment of our invention, Fig. 2 is a front view, Fig. 3 is a section along the line 3-3 of Fig; 1,'and Fig. 4 is a section through one of the main supporting planes from front. to rear.

Incarrying out our invention, We provide a frame which may be of any approved construction. In the drawings we have shown this frame as comprising the four vrods l,

2, 3, and 4, secured together by the braces 5.

45 In the main frame is disposed4 a driving motor M which may also be of any approved type. This motor 1s connected to the shafts 6 and 7 bearing the propellers 8 and' 9,v respectively. 3The motor 1s preferably e machine, as shown in Fi 3. The operators seat l0 is on the opposite side of the center'.

The construction thusfar described is ordlnary, and forms no part of our invention.

At A and B, we have shown the main sup- "porting planeswhich are disposed at the front and rear of the device, as shown in Figs. 1 and 3. These planes are warped in a double curve Fig. 4 shows a sect1on of one 'of these planes. It will be observed that the front portion is curved upwardly, as shown at a so as to form an inclined surface, oiTeriug resistance to the air. The rear por- .tion azvis curved in the opposite direction.

At the ends of the planes A and B, we provide a flexible portion C; It consists of the flexible ribs c covered with canvas or other material d. The normal position of this flexible portion c is that shown in Fig. l, but it may beclosed together 'like a web, a1-

ways extending again when the closing pressure is relieved.

Secured to each end of the plane A and extending downwardly are the side planes E and F, while similar side planes H and K are secured to the ends of the plane B. `The rear edge of these planes comes out to the y ends of their respective supporting planes to which they are joined at their tops, but are inclined inwardly, as shown in Fig. 2, so that their forward edges contact with the main supporting plane nearer to the center of the device. Thus the forward edges of the planes E and F contact with the main supporting plane A at e and f, respectively, while their rear edges contact with the plane at c and f. Below the main plane A is av when the machine tips, there will be a resist-- ance against the lower surface of the side plane, on theside'which is tipping downwardly and also a resistance on the upper surface of the side plane which is being tipped upwardly. Moreover, the motor and frame v-work being the heavy parts of the device tend to make the center of gravity low, and

.these parts tend to deseen when any tipping occurs, thus automatically righting the machine. The side planes, as stated before, are ,inclined inwardlyso as to present a resistance, or lifting surface when the machine is being urged forward.l The rearward in- Aclination of side,` .planes tends strengthen the device, since the greater part of the" strain comes in a horizontal direction,

and thereifore, .partxoffthis strain is taken;

lu'p `in direct tension'- on the side planes'. I

Incase :the I'nacline should descend and' tipr'so 'that one o f the supporting planes' ,strikes the groundfor any other, obstacle-,the
