The present invention is directed to flying machines and more particularly is concerned with an improved serviceable toy airplane and the objects, advantages, and features thereof will be apparent from a careful consideration of the following detailed disclosure viewed in the light of the accompanying drawing wherein:

Illustrative of the embodiment disclosed, the knock down toy airplane according to the invention is generally denoted A and comprises an elongated substantially V shaped channeled one piece body or chassis C having the inclined but diverged sides II provided with outwardly and downwardly turned flanged or hooked tracks 12 spaced from companion sides H and defining therewith longitudinally disposed grooves i3. These tracks and grooves are utilized to slidably but frictionally guide the hollow propeller carrier P, the hollow front wing mount S, and the hollow rear wing carrier R, longitudinally of the channeled body C.

For this purpose it will be observed that the propeller carrier P, the rear tail carrier R, and the front wing or intermediate carrier S each includes turned over flanges Hi. In case of the propeller carrier P, flanges or hooks l4 extend upwardly and outwardly and are integral with the laterally projecting lugs [5 (Fig. 3) forming an integral part of casing 16 of the propeller carrier or mount P and this casing includes a plurality of struck out tapered and hollow and alined nipples l1 through a pair of which bent terminals I8 of sides I9 of a wire bail or loop 20 are threaded and appropriately rotatably sustained and it will be noted that one end 25 of a helicoidal spring 22 is disconnectably fastened to the swingable loop 20 while another end 23 of spring 22 is appropriately threaded into a transverse brace 24 sustained by swingable legs 25 of a pivoted truck generally denoted T having a lower fixed brace 26 provided with fixed shaft extensions 21 for rotatably supporting wheels 28. However it should be observed that the upper ends of legs 25 include concavo-convex ears 29 rotatably held against bearings 30 by suitable upset fulcrum pins 3| secured to these bearings Which form a part of the front wing carrier or mount S.

The inclined flanges M of the hollow mount S and the rear wing hollow carrier R are also frictionally and slidably guided within channels l3 and on track l2 and in the case of hollow mount S (Fig. l), flanges M are integral with the in- 20 clined sides 32 of the irregularly shaped casing 33- provided with the longitudinally arranged dome shaped wind chute 34 integral with laterally extending shoulders 35 provided with laterally projecting lugs 36 fixedly carrying the front wings 3'? each appropriately reinforced by the several ribs 38.

In the case of the rear wing mount R (Fig. 5), the inclined hooked flanges M are integral with and spaced from the inclined sides 39 of the hollow casing llil. Thus as in the case of the propeller mount P and the front wing mount S, a suitable slidable but frictional connection defined by the interhooking and overlapping flanges E2 of the channeled member or body In and the several flanges M of the mounts P, S and R and consequently each of the latter may be adjustably moved and set longitudinally of the channeled supporting member 10. It follows that each and every of these aerofoil mounts may be readily slidably removed from the channeled member Hi. It should be noted however that casing Ml of the rear mount R is provided with flanges M to which the rear wing 42 is fixedly secured.

Extending upwardly from the rear wing 42 is the steering fin 43 having flange 44 secured to central depressed portion 45 of the wing i2 and the central part 46 of casing 40 by suitable pins 46. Wing 42 is preferably stamped out of relatively thin aluminum stock and is suitably embossed as at 41 to provide rigidity and it will be observed that fin 43 includes a rear tail portion 38 or rudder which can be swung and set frictionally relative to the fixed fulcrum pin 49 carried by fin 43. Hence the rudder 48 may be adtowards the left or right. The rear wing 42 is also provided with a reduced tail or rubber 55 which maybe hinged and frictionally set in respect to fixed'fulcrum pin 5|. Rudder 50 may be considered as the steering means to' direct the plane in a vertical direction. If rudder 59 or elevator steering means is tilted slightly upwardly the plane will elevate. On the other hand if the steering elevator is set to a downwardly inclined position the plane will move in va downward direction.

Associated with the channeled body ID in the longitudinal groove thereof is a motor 5| taking the formof a plurality of sensibly resilient but relatively durable elastic cords, the ends of which are attached to the front and rear connectors 52 and 53 each provided with a lug 54. The lug 54 of the rear connector 53 is fixedly fastened by a rivet 55 to the chassis or channeled member m while lug 54 of the front connector 52 is also perforated to threadably receive first the rear curved portion 56 and subsequently the rectilinear portion 5i of the hook generally denoted H which includes a downwardly directed and inclined part 58'merging with arectilinear shank or shaft 59 integral with a loop shaped driving head or connector broadly designated 60 disposed substantially normal to shank 59 and comprising the rectilinear curved part 6|, the intermediate curved part 62, the rectilinear part 63 disposed laterally of shank 59, the curved part 64, the rectilinear part 65 and therearwardly extending projection or nose 66. In other words parts 6| to 55 may be considered as spaced loop shaped arms disposed transversely of shaft 59 and constituting abutment means against the stop 61 struck out ofpropeller 68.

If shaft 59 be rotated, the propeller is rotated and if the latter be rotated, shaft 59is rotated. This action results in the connection between the connector or hook H and the propeller. During the unwinding of the motor 5| shaft 59 drives the propeller by reason of pinor nose 65 passing into an'opening in portion 61 of the propeller and the spacer 69 which is also caused to rotate, and the'latter is held yieldingly against bearing 10 by the elastic motor 5|. Conversely, if the propeller is rotated towind up the motor 5|, such action causes hook H or connector to rotate bodily and of course the spacer 59 rotates relative tobearing I0. Thus on winding of the motor the rear eye of the connector or hook H characterized by parts 56, 51 and 58 rotate the front connector 52 and the latter twists the cords of the elastic motor to the desired tension.

With suflicient energy stored up in motor 5|,

' the airplane may be allowed to fly. upon releasing of the propeller. Thus the motor starts to lose its energy although the propeller is rapidly rotating. During such rotation the longitudinally disposed bore of the dome or wind channel 34 of the front wing mount S allows air currents to pass therethrough in respect to obtaining increased lifting power and stabilizing the flying action of the plane and the same of course may be said of the vents defined by-nipples l1 and it will be observed that the 'rear end of propeller mount P and the front end of the rear wing mount R each includes a top fin H and the side fins I2 and if desired side fins 12 of the mount P may be diverged sufficiently to frictionally straddle legs 25adjacentthe spaced rotatable ears 29 (Fig. thereof to set the truck T in a desired tilted position against the energy of the spring 22 which cushions the shock imparted to" the wheels 28 on landing of the plane.

The stabilized cabin S according to Fig. 10 is along the lines of the stabilized casing 33 illustrated in Fig. 4 and differentiates therefrom in the provision of a'pair of spaced but fixed partitions dividing the cabin or casing 33 into three longitudinally disposed and separate compartments of which the central compartment 34' may be considered as the wind channel or chute while the side compartments 35' if desired may have their outer ends closed as is well understood to simulate passenger cabin means.

In the broader aspects of the invention, I do not desire to be understood as limiting the embodiment thereof to details herein shown'illustratively as a wide variety of modifications may be made within the scope of the appended claims without departing from the spirit of the invention.
