AIRPLANE TYPE KITE Filed March 21, 1947 Patented Jan. 3, 1950 AIRPLANE TYPE KITE Alphonse J. Tomczyk, Chicago, and Melvin C. Spreitzer, Des Plaines, Ill.

Application March 21, 1947, Serial No. 736,210 claims. (ol. 244-454) f, The present invention relates generally to kites. More particularly the invention relates to that type of kite which is shaped or des-igned to simulate a conventional single Wing variety airplane, consists of a longitudinally extending beam, an empennage in the form of horizontal and vertical fins, a pairA of complemental, oppositely extending wing sections on the front end of the beam, and a body or fuselage simulating strip along the beam, and is so constructed that the Wing sections and the vertical fin are detachable in order that the kite may be transported or stored in knock-down form and when in such form is capable of being retained in a small sized container.

One object of the invention is to provide a kite of this type which is an improvement upon, and has certain inherent advantages over, previously designed kites of the same general character and is characterized by the fact that it is essentially simple in design and construction and possesses extremely desirable flying characteristics.

Another object of the invention is to provide an airplane type kite of the last mentioned character in which each of the wing sections comprises in addition to a covering a single or one-piece U- shaped frame forming wire and is connected to l the front end .of the longitudinally extending beam by Way of a pair of brackets to which the ends of the Wire are removably attached.

Another object of the invention is to provide a kite of the type and character last mentioned in which the coverings of the wing sections are in the form of elongated envelopes which have open inner ends, are adapted to be mounted in place by sliding them inwards around the U- shaped frame forming wires, and provide spaced apart upper and lower surfaces for the wing sections.

Another object of the invention is to provide an airplane -type kite of the type and character under consideration in which the inner open endsr `piece of comparatively stii cardboard vand are bonded or adhesively connected to the bottom face of the longitudinally extending beam.

.f A still further object of the invention is to provide an airplane type kite which ls generally of new and improved construction and by reason of its specilic design is capable of being produced at a comparatively low cost.

Other objects of the inven-tion and the various advantages and characteristics of the present airplane type kite will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.

In the drawing which accompanies andforms a part of this specification or disclosurev and in which like numerals of reference denote corresponding parts throughout the several views:

Figure 1 is a perspective of an airplane type kite embodying the invention, certain parts being broken away for purposes of illustration;

Figure 2 is an enlarged fragmentary plan view of the front end of the kite, illustrating in detail the manner in which the ends of the U-shaped frame forming wires of the wing sections are detachably connected to the front end of the longitudinally extending beam, and also the manner in which the inner open ends of the envelopes constituting the coverings for the wing sections are connected together;

Figure 3 is a vertical transverse section through one of the Wing sections;

Figure 4 is an enlarged side view of one ofthe brackets 'whereby the wing sections are detachably connected to the front end of the longitudidesigned to simulate a monoplane, i. e., a conventional single wing variety airplane. As its prinf cipal components or parts the kite comprises a` longitudinally extending beam 6, an empennage or tail structure 1, a pair of wing sections 8, and a body or fuselage simulating strip 9.

The beam 6 is preferably formed of wood. It I constitutes the main supporting or reenforcing instrumentality of the kite and is square in cross section.

The empennage 1 serves as the tail of the kite and consists of a horizontally extending iin i0... Both are and a vertically extending vfin Il. formed of comparatively stiff cardboard.v The rudder of the empennage of aconventional airl *Y plane. It is centrally positioned with respect to the horizontal fin and extends upwards from, jand is suitably connected to, the rear end of the Y Y longitudinally extending beam 6. Preferably the; vertical n II is connected to the beam'byhavv ing the bottom Vmargin thereof confined and tting within a vertical longitudinally extending slit I2 in the rear end of the beam. This ar rangement makes it possible to detach the vertical fm from thevbeam in connection with transporta-V tion'or storing of -the kite as a whole. It is con-V templated that thekite will be merchandised in knock-down form and assembled for use. If, inY

connectionwith assembly, it is desired permanently to'secure the vertical n II in place Yit is only necessary to cement or adhesively connect the bottom margin of Vsuch iin to the facesof theA beam'that define the slit` I2i. As an alternative, brads (not shown) :may be driven transversely through the slitted `rear end of the beam 6 and positioned so as to pass through the confined lower margin of the n. 1

Thewing sections 8 are located at the 'front end of, andV project outwardsin opposite directions from, the front end ofthe longitudinally extending beam 6 and are complemental. They serve as the main supportingV surfaces for the kite and,4 as hereinafter described,V are detachably` connected to said frontend ofthe beam 6. Each wing consistsv of. a single or one-piece U-shape'd` frame forming vwire I3 and vacover formingen- Vvelope I4. lil/hen the wing sections 8 are Yin attachedfor connected relation with the beam the ends of thewires I3 are disposed adjacent the front end ofthe beam.; `The front legsofthe wires formfthe'front spars of the wing sectionsA and the rear legs of the' 'Wires form the rear spars. VIhecurved or rounded intermediate portions of the wires constitute the tip portions of the, frames ofV the wingv sections.l The ends of the wiresv I3 -iitislidablywithin'the ends of a 'pair of tubes I5.' 'The latterioverlie .andY extend transversely of the front 'end of the'beam 6.v

By providing the frontlegs. of the wires I3 with a rear sweepback sliding of the envelopes I4 into place is facilitated.

The length of the envelopes I4 is such that when the envelopes are in place'the open inner'ends terminate adjacent theVv ends of Vthe frame form-J ing wires I3.
