12 Claims. (01. 244-154) This invention relates to kites and its object is sembled, extend 12" each from the center of the to provide a kite having the appearance of an block. The stem is'shorter than the other airplane which, when flown in attachment to a Spars, and extends forward from the center ,of, thread or string, will rise and fly like an airplane the block a distance of about 6". A considerglider, steadily, without diving or traveling forable part of this length is in front of the forward 5 ward against the wind.

'The kite here illustrated is constructed of a secured by a gummed tape 8. This shortens the 5 light wooden frame, paper wings, a paper tail, forward edge and makes a shallow pocket midstifiening ribs, and gummed paper tapes asconway between the ends and slightly forward of the necting means. The frame consists of a con middle point between the forward and rear edges necting block I a longitudinal beam 2, wing ribs Such pocket enables the wing blank, when, placed 40 3 and 4, and a forward stem 5.

These holes enter the by placing it thereunder and connecting its op- 50 block from the corners and on the diagonals posite ends to the rib ends by patches I3 and thereof, at an inclination of approximately 11 M respectively of gummed paper. These ends with the top and. bottom planes of the block. are thus connected successively and the wing is The beam 2 and wing ribs 3 and 4 are equal to drawn taut after being thus attached to one end,

The forward and rear edges of the wing blank are then connected to the stem and longitudinal beam by similar gummed paper patches l5 and it respectively. In making these latter attachments, the edges of the wing blank are pinched around the under side of the spars far enough to take up any slack which there may be in the edges, so that after the gummed patches have been applied, the edges are stretched taut and straight so that they cut the air cleanly without fluttering.
Fig. 4 illustrates in principle how the rear edge of the wing blank may be thus caused to embrace partially the beam 2. The operator in making the connection presses upward with the thumb and finger of one hand on opposite sides of the beam beneath the wing, and downwardly on the beam with a finger of the other hand while laying the adhesive tape on the upper side of the wing across the beam and holding it until the adhesive sticks firmly. Either or both edges may be thus bent around the beam and stem respectively to a greater or less extent, depending on how loose the edges may have been initially. There may be no embracing whatever of the spar by the edge of the wing; but the capacity for doing so, in the manner described, affords ameans by which the desired condition of tautness of the edges, and particularly of the forward edge, may be obtained.
The tail is made from a blank of paper which is folded double on the middle line and bent outwardly at each side on lines equidistant from the outer edges so as to form an upright rudder vane l1 and two horizontal stabilizer vanes l8 and 9.
. In the present illustration the tail blank is approximately a semicircle and is folded on approximately radial lines so spaced as to divide the blank into approximately equal Sectors, the middle sectors of which form the vertical rudder and the outer sectors the fan shaped stabilizer vanes. The fold between the sectors which form the rudder is reinforced and stiffened by a gummed tape 20 which is folded double and applied to the outside of the fold between the rudder sectors. To apply this tall assemblage to the frame, the parts at the base of the rudder are spread apart as shown at Fla and l lb in Fig. 5 so as to straddle the rear partof the beam 2, and these embracing parts are then secured by gummed tapes 2| and 22 which are stuck to the sides of the beam and overlap the parts Ila and Nb to a sufficient extent. The stabilizer vanes are braced and held substantially in a horizontal plane near their rear edges by a stiffener 23, which may be a hexible and resilient reed like the wing braces 9 and I passed through a hole in the beam and extended at opposite ends over the vanes 18 and I9, to which it is secured at a sufficient number of points by gummed patches 24 and 25. The tail vanes are notched to permit placement of this brace on the upper side of the stabilizer vanes. By means of the brace 23 and the reinforced fold between the panels of the rudder, the rudder and stabilizer vanes are adequately held substantially in the vertical and horizontal planes respectively when the kite is in the air, or nearly enough so to keep it steady in direction and elevation.
The foregoing detailed and specific description is intended to give complete information enabling the artisan to put the invention into prac- 70' tice. But it is not to be construed as limiting my claimed protection to all details of such description. Many variations in dimensions, proportions and construction of the various parts of the kite may be made within the scope of such protection. For instance, the kite may be made larger or smaller than indicated, the proportion of length to width of the wings may be considerably varied in both directions, and the shape and construction of the tail vanes may be varied. The wing surfaces may be made of two pieces of paper or equivalent fabric instead of one piece as previously described, each of the two pieces being attached at its tip to the rib end and at its base near the forward and rear edges respectively to the longitudinal beam. Each marginal part of the wing base may be thus attached by means of gummed tapes, and in being attached is stretched tight, so that the same ultimate effect as previously described in respect to the firm edges, the up tilted forward margin, and the pocket effect in the combined wing structure, is obtained as already described. Other equivalent modes of forming and connecting the members of the frame may also be used. For instance, the two longitudinal spars 2 and may be made in a single integral piece, and so may the two wing ribs 3 and 4, or a plurality of ribs may be provided to support and brace each wing.
Principles which I consider important and desire to protect broadly are the following:-
The forward edge and an adjacent area of the wings is tilted up at an angle of substantial magnitude with respect to the rear portion thereof in the fore-and-aft dimension of the kite, sufficient to prevent forward flight of the plane beyond the control of the string to which it is attached and to prevent a down draft of air on the top of the wings. the wing area is thus tilted upward; but this proportion is not a narrowly limiting factor. It should be less than one half, but not less than one fourth. Due to the particular construction here shown,.thc angle of up tilt is greatest in the middle of the kite and diminishes gradually toward the wing tips. Due to this up tilt the kite always fiies somewhat to leeward of the person controlling it and maintains a light strain on the string. That is, it does not travel to windward enough to slacken the string or cause the pull of the string to tilt the kite downward and make it diveu But at the same time the up tilt is small enough to provide a smooth air flow surface on the under side of the wings and enable the impingement of air on the rear fraction of such surface to lift the kite.
The formation of a pocket by slitting or notching and shortening the forward edge and adjacent area of the wings is an important factor in accommodating such an inextensible material as paper simultaneously to the dihedral angle of the wings and the up tilt of the forward fraction of the wings. The angle between the wing ribs, which in this case is 158 and may be slightly greater or less, establishes a dihedral wing angle which insures stability.
The plane of the stabilizing vanes is approximately coincident with or parallel to the front to rear elements of the wing surfaces in rear of the ribs 3 and 4. There need not be an exact paral lelism, but there is such a near approach to parallelism that the stabilizing vanes hold the kite substantially level in the front to rear dimension,
I consider that my invention comprises both generic principles or features as above stated, and also the specific details herein disclosed.
What I claim and desire to secure by Letters Patent is:
