Application led August 10, 1908. Serial No. 447,813.

To all whom it may concem: f

Be it known that I, SILAs J. CONYNE, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and yuseful Improvement in Kites, and declare the following to be a full, clear, and exact description of the the art to which it pertains to make and use the same, reference bein had to the aecompanying drawings, whic form a part of this specication.

'My invention has for its object to reduce a kite which combines lightness wit great lifting power.

A further object of my invention is to provide means for edectively balancing a kite lwithout materially increasing the weight of the kite above the weight of the 'parts which exert the lifting power.

A further object of my invention is to produce a kite which shall `be simple in construction, cheap, durable, and efficient in operation. v

The various features of novelty lwhereby my invention is characterized will be hereinafter pointed out with particularity in the claims; but for a full understanding of my invention and of its various objects and advantages, reference is to be had to the lfollowing detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a rear elevation of a kite arranged in accordance with one form of my invention; Fi 2 is a` front elevation of the same; Fig. 3 1s a bottom plan view; Fig.,4: is a top plan view; Fig. 5 is a section taken on line 5 5 of Fig. l; Fig. 6 is a front ele-.

vation of a second form of my invention; Fig. 7 is a bottom plan view of the device shown in Fig. 6; and Fig. 8 is a section taken on a plane passing through the longitudinal center of Fig. 6.

Referring to the drawings, and especlally to Figs. 1 to 5, A is a kite, B is a keel extending along the lo member A, and C is a bridle connected at its ends to the keel and at an intermediate point to a captive line D. The keel 1s preferabl of a peculiar construction, decreasing gradually "from the lower end where 1t takes the form of a V-shaped roj ection to a vanishing point at the top o the kite. In other words, at the top of the kite tudinal center of the' there is little or nothing of the nature of a keel while, as the lower end is approached, a keel of gradually increasing proportions rises from the front of the kite. By this arrangement the kite is guided in its travel -and a powerful influence is exerted to maintain its longitudinal axis in a vertical plane. The keel need not, of course, extend throughout the entire length or height of the kite2 nor need it be triangular in crosssection. Such an arrangement is, however, a convenient and natural one where the simple and inexpensive mode of construction of the apparatus which I have illustrated is adopted. v

Inpthe apparatus as illustrated there isha suitable frame a of the requisite strength and lightness, a keel backbone I), and a covera. The cover is stretched across the frame so as to be moderately taut except throughout a longitudinal central panel, the portion forming this panel being preferably moderately taut at the top and becomin looser and looser toward the bottom unti at the bottom, a degree of looseness is attained which permits the cover to be bellied out to a considerable extent. The corners of the panel are indicated byaz, a", a4, and a5, respectively. The keel backbone lies upon t-he longitudinal center of the central panel and is preferably secured thereto. By taking hold of the backbone itv may be moved in a plane'passing through the center of the kitel and at right angles thereto until the central portion of the cover is drawn into a tautridge which decreases gradually from the lower end toward the u per end. This ridge forms the keel.v It willpbe seen that the Iridge-like keel may be produced and maintained automatically in the act of iiying the kite by simply :tastenin the bridle to the backbone of the keel. Vhen the kite is notl being flown the keel collapses and leaves the device flat and capable of being entirely collapsed in any suitable manner.

` It will then be seen that a prominent and highlyV effective keel is provided without adding more weight to the kite than is due to the slightly increased amount of covering material necessitated by the fullness of the central panel. Moreover the entire cover may be applied as a single piece, if desired, making production of the apparatus simple and inexpensive. I prefer to cut the cover in a single piece so shaped that when it is secured at the corners of the frame, the two side port-ions will l'be stretched tightly while the central panel is left loose as previously described. If desired the cover may be fastened to` the two frame members extending from a2 to a1 and from a3 to 0)?, respectively, since the keel will thereby be more sharply defined.

The frame is preferably so formed that it affords anchoringY points at a* and a'S respectively, and also so 'as to 'ermit the cover to be secured inplace along ines connecting the corner a2 with the corner a* and the corner as with the corner a5. The keel may thereby besharply defined. Atie member E is preferably arranged between the corners a4 and a5 so as to prevent them from spreading and permitting the keel to flatten out under the strain to which it is subjected during the flying of the kite.

In Figs. 6 to 8 I have shown a slight modification. The aeroplane A andthe keel B are the same as in the other form except that a strip F is placed upon the member A in rear of the keel so that the kite Viewed from the rear presents a continuous plane surface. This .forms a pocket G within the keel and, as this pocket might catch the wind and cause the kite to get beyond the control of the operator, I form an outlet. B2 in the keel at a point between the ends thereof.

While I' have described in detail only those forms of my invention which I now deem to be the most practical, I do not desire to be limited to these specific forms since, in its broader aspects, my invention may take various other forms as will be evident from the terms employed in the definitions of my invention constituting the appended claims.

Having now fully described my invention,

what I claim as new and desire to secure by 2. A kite comprising an aero lane anda keel extending longitudinally t ereof, said keel having a triangular cross section atv the lower end of the aeroplane and decreasing gradually in width and in height until itv vanishes adjacent to the'upper end of the aeroplane, and a bridle connected to vthe lkeel along the center line thereof.

3. A kite comprising a frame, a cover secured to said frame so as to leave a' cent-ral portion increasing gradually in looseness from the top toward the bottom, and a bridle arranged upon said central portion at the longitudinal center line thereof.

4. A kite comprislng a frame, a cover secured to said frame so as to leave a central portion increasing gradually in looseness from' the top toward the bottom, a stiffening rib extending down the center of said cen' 6. A kite comprising a frame, a coverv secured to said frame so as to leave a central portion which at the top lies Vsubstantially taut in the lane of the main portion and increases gra ually in looseness toward the bottom, a stiiiening ribl extending along the longitudinal center of said central portion, and a bridle secured to said rib.

7. Al kite comprising 'a frame, a cover secured to said frame so .as to leave a central portion which at the top lies substantially taut in the plane of the main portion and increases radually in looseness toward the' bottom, a ridle secured to said central portion at the longitudinal centerline thereof, and a tie member extending across thelower end of said central portion, saidtie member bein shorter than the width of said central portion at that point.

8. A kite comprising a fiat bod member anda hollow keel extending longitudinally thereof, said keel increasing gradually in size from a vanishing point at the top of the body toward the bottom, and being open at the bottom, and having an opening through the front face between the ends thereof.

9. In a kite, a framecomprising two arallel members and a cross member, a s eet secured to the ends of said members so as to form taut portions outside of said two .parallel members and a portion extending between said parallel members and increasin graduallyin looseness from the top towar the bottom, and a fourth frame member lying between and parallel with said two parallel members and secured to the loose portion of said sheet.

10. In a kite, a frame having at least six corners four of which formy the corners of a toward the other and the portions outside of the rectangle taut, a stiffening member extend-l. ing lengthwise of and secured to said loose portion at the center thereof, and a bridle connected to said stiflening member.
